Growth and yield models at different scales are useful tools for forest stakeholders. Adequate simulation of forest
stand conditions after different silvicultural scenarios allows stakeholders to adopt appropriate actions to maintain
forest integrity while forest products and services are obtained to benefit society as a whole. SIMANFOR is a platform to simulate sustainable forest management alternatives, integrating different modules to manage forest inventories, simulate and project stand conditions and maintain systems security and integrity. SIMANFOR output is compatible with an Office environment (Microsoft or Open), allowing users to exchange data and files between SIMANFOR and their own software. New developments are being planned under a web 2.0 environment to take advantage of user input to improve SIMANFOR in the future.

Producción Científica
Context
Information about variations in basic density (BD) and carbon content (%C) along tree stems is key to assessing forest carbon sinks.
Aims
The aim of the study was to determine any differences in %C and BD between different woody tissues (bark,
sapwood and heartwood) in two widespread European oak species (Quercus pyrenaica and Quercus petraea).
Methods
Twenty trees were felled in northern Spain, and 317 discs cut from the trees were dried and analysed to determine %C and BD.
Results
There were significant differences in %C between bark, heartwood and sapwood, and between species. There
were also significant differences in BD between the tissues (heartwood>sapwood>bark), and the BD was higher in
Q. petraea than in Q. pyrenaica. Both %C and BD varied along the stem.
Conclusion
More accurate estimates of carbon contents were obtained by using specific values for different heights and anatomical parts, than by using single values.

In this paper we present a review of forest models developed in Spain in recent years for both timber and non timber production and forest dynamics (regeneration, mortality,..). Models developed are whole stand, size (diameter) class and individual-tree. The models developed to date have been developed using data from permanent plots, experimental sites and the National Forest Inventory. In this paper we show the different sub-models developed so far and the friendly use software. Main perspectives of forest modelling in Spain are presented.

Producción Científica
Environmental variability and site productivity relationships, estimated by means of soil-site equations, are considered a milestone in decision making of forest management. The adequacy of silvicultural systems is related to tree response to environmental conditions. The objectives of this paper are to study climatic and edaphic variability in Mediterranean Maritime pine (Pinus pinaster) forests in Spain, and the practical use of such variability in determining forest productivity by means of site index estimation. Principal component analysis was used to describe environmental conditions and patterns. Site index predictive models were fitted using partial least squares and parsimoniously by ordinary least square. Climatic variables along with parent material defined an ecological regionalization from warm and humid to cold and dry sites. Results showed that temperature and precipitation in autumn and winter, along with longitudinal gradient define extreme site qualities. The best qualities are located in warm and humid sites whereas the poorest ones are found in cold and dry regions. Site index values are poorly explained by soil properties. However, clay content in the first mineral horizon improved the soil-site model considerably. Climate is the main driver of productivity of Mediterranean Maritime pine in a broad scale. Site index differences within a homogenous climatic region are associated to soil properties.

The driest part of the Argentinean pampas is occupied by semiarid woodlands
dominates by Prosopis caldenia Burkart (Calden). Calden pods are a highly valuable
fodder supplement for livestock but its production is highly variable. Our objective was
to analyze and model the temporal pattern in inter-annual variability of Calden pod
production. Our key hypothesis is that weather conditions are the main determinant of the pod masting behavior. Tree size and climatic variables were evaluated as explanatory covariates using a zero-inflated log-normal modelling approach. The proposed final model structure incorporated 25 parameters, including four variance components, two intercepts for both the logistic and the log-normal parts of the model, and nineteen parameters associated with fixed effects. Climate had a strong influence on the flowering-fruiting Calden process and on the inter-annual variability of the final pod production at the tree level. Temperatures during bud breaking, flowering and fruit shedding, together with the precipitation from the final month of fruit shedding and the total amount of the prior vegetative cycle, were the main weather covariates that affect the processes.

Although water deficit and iron deficiency chlorosis are common environmental stresses in the Mediterranean area, few data are reported in the literature on their effects on vineyards, when acting simultaneously. The main objective of this research was to study the combined effects of iron deficiency and water status on vigor, yield and fruit composition in rainfed vineyards. Moreover, the investigation aimed to evaluate the feasibility of using foliar chlorophyll content (Chl) and predawn leaf water potential (LWP), measured at veraison, to assess potential quality of grapes in the framework of precision viticulture. For this, 24 non-irrigated ‘Tempranillo’ vineyard subzones were monitored in Ribera del Duero (North-Central Spain) during three consecutive seasons (2011-2013). The analysis of variance and principal component analysis showed that malic acid concentrations of the must were impacted only by Chl, whereas total soluble solids and total acidity were mainly modified by LWP. Both water and iron status reduced yield and berry weight and had additive effects on extractable anthocyanin content in grapes, total polyphenol index and color density of the must. In all seasons, the ratio Chl/LWP had a better predicting value for quality parameters of these grapes than leaf area index, Chl or LWP individually. The present work demonstrates the potential interest of physiological indexes combining water status and foliar chlorosis as indicators of grape phenolic potential in rainfed vineyards affected by iron deficiency.

Bark beetles (Coleoptera, Scolytinae) carry a diverse filamentous fungal community
sometimes acting as vectors or carriers of phytopathogens. In this study, mycobiota carried by two
Tomicus species (Tomicus piniperda and Tomicus destruens) were investigated through (i) morphological
and molecular identification of taxa; (ii) taxonomic richness, diversity, evenness, dominance
and phoresy indices; (iii) ecological network analysis and (iv) statistical co-occurrence analysis.
The studied mycobiota were formed by eleven taxa and showed a moderate fungal diversity with low
evenness. The fungus Sydowia polyspora was significantly abundant and dominated the community.
All the fungal taxa were randomly associated. Both insect species (T. piniperda and T. destruens) were
collected from plantations of Pinus radiata infected by Fusarium circinatum. The ecological factors that
could drive community ecology and phoretic links between fungi and bark beetles are discussed.

Pine Pitch Canker disease, caused by the pathogenic fungus Fusarium circinatum, affects
conifer species worldwide. However, the virulence of the pathogen may be affected by the presence
of mycoviruses. The aim of this laboratory-based study was to investigate the probability and rate
of transmission of F. circinatum mitoviruses FcMV1 and FcMV2-2 via microconidia. Ten isolates of
mitovirus-infected F. circinatum were subcultured to produce a total of 100 single-spore colonies
(ten replicates per isolate). The total RNA and cDNA obtained from each spore isolate (monosporic
culture) were amplified by PCR with specific primers for detection of F. circinatum mitoviruses FcMV1
and FcMV2-2. The mitoviruses were detected in a high percentage of the individual spore isolates
(between 60% and 100% depending on the fungal isolate). However, the probability of transmission
was not statistically significantly associated with either the F. circinatum isolate or the viral strain.
A high proportion of transmission via microconidia is critical for development of a biological control
program against Pine Pitch Canker (PPC) disease in forests. However, further studies are needed to
establish the effect of these mitoviruses on the virulence of F. circinatum.

Fusarium circinatum is the causal agent of pine pitch canker (PPC), one of the most
devastating forest diseases worldwide. This fungus causes severe damping-off in pine seedlings and
growth reduction, wilting and the development of cankers in pine forests and plantations. A draft of
the complete genome sequence of this phytopathogen was recently made available. This information
was used to annotate in silico the gene Fcrho1 as a putative homolog of Rho1 GTPase genes. In this
study, we generated Fcrho1 deletion mutants in two F. circinatum wildtype strains isolated from
damaged trees in northern Spain. For that, we used a modified version of the OSCAR methodology,
an approach not previously used in F. circinatum that allows the generation of deletion constructs
in a single cloning step. The conidiation and spore germination of the resulting deletion mutants
were not affected, neither the hyphal morphology. However, the mutant strains showed significantly
reduced growth in vitro and more foamy macroscopic hyphal morphology than their corresponding
ectopic and wildtype strains. Finally, an in vivo virulence assay showed that the reduced in vitro
growth rate characteristic to the deletion mutants does not impact their pathogenicity.

Pine pitch canker (PPC) is a major threat to pine forests worldwide because of the extensive
tree deaths, reduced growth, and degradation of timber quality caused by it. Furthermore, the aggressive
fungus responsible for this disease (Fusarium circinatum) can also infect pine seeds, causing damping-off
in young seedlings. This study proposes an approach based on coating treatments consisting of
natural products to ensure seed protection. Seeds from two pine species (the most sensitive to this
disease, Pinus radiata D. Don, and a more resistant one, Pinus sylvestris L.) were coated with single
and binary mixtures of low and medium molecular weight chitosan and/or ethanolic-propolis
extract. The germination rate, pre- and post-emergence mortality, total phenolic content, and radical
scavenging activity were assessed. All treatments, and especially the one based on chitosan oligomers,
had a beneficial impact on P. sylvestris seedlings, significantly enhancing survival rates and displaying
a positive influence on the total phenolic content and on the seedlings’ radical scavenging activity.
Conversely, non-significant negative effects on germination percentages were observed in the case of
P. radiata seeds. The proposed treatments show promise for the protection of P. sylvestris seedlings
against PPC.

The fungal pathogen Fusarium circinatum (Nirenberg and O’ Donnell) is the causal agent
of pine pitch canker (PPC) disease, which seriously affects conifer species in forests and nurseries
worldwide. In Europe, PPC is only established in the Iberian Peninsula; however, it is presumed that its
range could expand through the continent in the near future. Infection caused by this fungus requires
open wounds on the tree, including physical damage caused by insects. Therefore, a relationship
probably occurs between PPC and a wide variety of insects. The aim of this review is to outline the
taxonomic and ecological diversity of insect species with high potential association with F. circinatum
in Europe and elsewhere. The insects were classified as vectors, carriers and wounding agents
according to the association level with the PPC disease. In addition, we discuss the insect-mediated
spreading of PPC disease in relation to the different phases of forest stand development, from seeds
and seedlings in nurseries to mature stands. Lastly, to improve our predictive capacities and to
design appropriate intervention measures and strategies for controlling disease dissemination by
insects, variables such as geographic location, time of the year and host species should be considered,

Fusarium circinatum (Nirenberg and O’ Donnell) is the causal agent of pine pitch canker
(PPC) disease, one of the most devastating forest diseases worldwide. Long-distance spread occurs
mainly through the movement of infected seeds whereas at regional level, the movement of seedlings,
substrates, or containers may play an important role in fungal dispersal. Invasion of nurseries takes
place via infected seeds and further spread can occur by planting contaminated seedlings, especially
due to the possibility of infected plants remaining symptomless. Once established, F. circinatum spreads
by rain, wind, and insects. The natural spread of the pathogen is limited due to the short dispersal
distances of the spores and the fairly short flight distances of disseminating insects. In this review,
we summarize the currently known dispersal pathways of the pathogen, discussing both natural and
human-assisted processes. With the purpose of understanding how to best intervene in the disease’s
development in nurseries and forests, we outline the epidemiology of the pathogen describing the
key factors influencing its spread. Preventive measures to control the spread of F. circinatum locally
and globally are described with special emphasis on the challenges in implementing them.

Fusarium spp., as well as other endophytic or pathogenic fungi that form communities, have
been reported to be phoretically associated with bark beetles (Coleoptera; Scolytinae) worldwide.
This applies to Fusarium circinatum Nirenberg and O’Donnell, the causal agent of pine pitch canker
(PPC), which threatens Pinus radiata D. Don plantations in northern Spain. The main objective of
this study was to study the fungal communities associated with bark beetles and their galleries in
stands affected by PPC, with special attention given to Fusarium species. Funnel traps and logs were
placed in a P. radiata plot known to be affected by F. circinatum. The traps were baited with different
attractants: four with (E)-pityol and six with ethanol and α-Pinene. In addition, fresh green shoots
with Tomicus piniperda L. feeding galleries were collected from the ground in 25 P. radiata plots affected
by PPC. Extracts of whole insects and gallery tissues were plated on agar medium to isolate and
identify the associated fungi. A total of 24 different fungal species were isolated from the bark beetle
galleries constructed in logs and shoots, while 18 were isolated from the insect exoskeletons. Ten
different Fusarium species were isolated from tissue and insects. Fusarium circinatum was isolated
from bark beetle exoskeletons (1.05% of the Pityophthorus pubescens Marsham specimens harboured
F. circinatum) and from the galleries (3.5% of the T. piniperda feeding galleries harboured the pathogen).
The findings provide information about the fungal communities associated with bark beetles in
P. radiata stands in northern Spain.

Fusarium circinatum is the causal agent of pine pitch canker disease (PPC), affecting Pinus
species and other conifers (i.e., Pseudotsuga menziesii (Mirb.) Franco.), forming resinous cankers on
the main stem and branches and causing dieback in the terminal guide. This pathogen is spreading
worldwide, causing economic losses by converting plantations into standing timber without any
potential for future production. The disease was recently detected in Northern Spain in plantations
of Pinus radiata and forest nurseries. The aim of the work reported here was to study the role
of climatic and topographic variables, soil properties, and stand characteristics on PPC. For this
purpose, we surveyed 50 pine stands in Cantabria and quantified the percentage of trees showing
three symptoms in each stand: canker, defoliation, and dieback. We investigated the predictive
power of 30 variables using generalized linear models and hierarchical partitioning. Both approaches
yielded similar results. We found that the three symptoms correlated with different explanatory
variables. In addition, more trees exhibited cankers in the proximity of the coast and the Basque
Country. Additionally, our results showed that low canopy cover is related to a high level of the
dieback symptom. Overall, this study highlights the important variables affecting the distribution of
PPC in Cantabria.

Fusarium circinatum, the causal of pine pitch canker disease (PPC), is now considered among
the most important pathogens of Pinaceae in the world. Although in Europe PPC is only established
in the Iberian Peninsula, the potential endangered areas cover over 10 million hectares under the
current host distribution and climatic conditions. It is therefore a priority to test the susceptibility of
those species and their provenances, within Central and Northern Europe and find biological control
agents (BCAs) against the disease. In this study, the susceptibility of Pinus sylvestris, P. mugo and
Picea abies Romanian provenances to F. circinatum was tested using three inoculum doses. In parallel,
the potential use of Trichoderma atroviride and Trichoderma viride as BCAs against F. circinatum was also
tested. This study has demonstrated, for the first time, the susceptibility of P. mugo to F. circinatum.
Likewise, the susceptibility of P. abies was also confirmed. The fact that the Romanian provenance of
P. sylvestris has not been susceptible to F. circinatum suggests genetic resistance as a potential tool to
manage the disease. This, together with the apparent effectiveness of Trichoderma species as BCAs,
seems to indicate that an integrated management of the disease might be feasible.

Fusarium circinatum Nirenberg & O’Donnel is listed among the species recommended for
regulation as quarantine pests in Europe. Over 60 Pinus species are susceptible to the pathogen and
it also causes disease on Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and species in genera
such as Picea and Larix. The European Food Safety Authority considers the probability of new
introductions—via contaminated seeds, wood material, soil and growing substrates, natural means
and human activities—into the EU very likely. Due to early detection, constant surveillance and
control measures, F. circinatum outbreaks have officially been eradicated in Italy and France. However,
the global spread of F. circinatum suggests that the pathogen will continue to be encountered in new
environments in the future. Therefore, continuous surveillance of reproductive material, nurseries
and plantations, prompt control measures and realistic contingency plans will be important in Europe
and elsewhere to limit disease spread and the “bridgehead effect”, where new introductions of a tree pathogen become increasingly likely as new environments are invaded, must be considered.
Therefore, survey programs already implemented to limit the spread in Europe and that could
be helpful for other EU countries are summarized in this review. These surveys include not only
countries where pitch canker is present, such as Portugal and Spain, but also several other EU
countries where F. circinatum is not present. Sampling protocols for seeds, seedlings, twigs, branches,
shoots, soil samples, spore traps and insects from different studies are collated and compiled in this
review. Likewise, methodology for morphological and molecular identification is herein presented.
These include conventional PCR with a target-specific region located in the intergenic spacer region,
as well as several real-time PCR protocols, with different levels of specificity and sensitivity. Finally,
the global situation and future perspectives are addressed.

Pine pitch canker (PPC), caused by the pathogenic fungus Fusarium circinatum (Nirenberg
and O’ Donnell), is a serious threat to pine forests globally. The recent introduction of the pathogen to Southern Europe and its spread in Mediterranean region is alarming considering the immense
ecological and economic importance of pines in the region. Pines in forests and nurseries can be
infected, resulting in severe growth losses and mortality. The pathogen is known to spread in plants
for planting and in seeds, and results from recent studies have indicated that F. circinatum may also
spread through phoretic associations with certain insects. With this review, we aim to expand the
current understanding of the risk of insect-mediated spread of PPC in different parts of Europe.
Through the joint action of a multinational researcher team, we collate the existing information about
the insect species spectrum in different biogeographic conditions and scrutinize the potential of
these insects to transmit F. circinatum spores in forests and nurseries. We also discuss the impact of
environmental factors and forest management in this context. We present evidence for the existence of
a high diversity of insects with potential to weaken pines and disseminate PPC in Europe, including
several common beetle species. In many parts of Europe, temperatures are projected to rise, which
may promote the activity of several insect species, supporting multivoltinism and thus, further
amplifying the risk of insect-mediated dissemination of PPC. Integrated pest management (IPM)
solutions that comply with forest management practices need to be developed to reduce this risk.
We recommend careful monitoring of insect populations as the basis for successful IPM. Improved
understanding of environmental control of the interaction between insects, the pathogen, and host
trees is needed in order to support development of bio-rational strategies to safeguard European pine
trees and forests against F. circinatum in future.

Deep sequencing of small RNAs has proved efective in the diagnosis of mycovirus infections. In this study, the presence
of mycoviruses in ten isolates of the phytopathogenic fungus Fusarium circinatum was investigated by high-throughput
sequencing (HTS) of small RNAs. The contigs resulting from de novo assembly of the reads were aligned to viral genome
sequences. The presence of each mycovirus detected in the isolates was confrmed by RT-PCR analysis with four previously
described primer pairs and seven new pairs designed on the basis of sequencing data. The fndings demonstrate the potential
use of HTS for reconstructing previously identifed mitoviruses infecting F. circinatum.

There is a growing necessity to replace chemical agents with ecofriendly materials, arising from the impact on the environment and/or human health, which calls for the design of new broad-spectrum fungicides. In this work, chitosan oligomers (COs), propolis (Ps) and silver nanoparticles (AgNPs) mixtures in solution were assessed to control the growth of different phytopathogenic fungi and oomycetes in vitro. Binary solutions of COs-Ps and COs-AgNPs evinced the highest antifungal effect against Fusarium circinatum and Diplodia pinea fungi, respectively, with a ca. 80% reduction in their mycelial growth. The COs solution by itself also proved to be greatly effective against Gremmeniella abietina, Cryphonectria parasitica and Heterobasidion annosum fungi, causing a reduction of 78%, 86% and 93% in their growth rate, respectively. Likewise, COs also attained a 100% growth inhibition on the oomycete Phytophthora cambivora. On the other hand, Ps inhibited totally the growth of Phytophthora ×alni and Phytophthora plurivora. The application of AgNPs reduced the mycelial growth of F. circinatum and D. pinea. However, the AgNPs in some binary and ternary mixtures had a counter-productive effect on the anti-fungal/oomycete activity. In spite of the fact that the anti-fungal/oomycete activity of the different treatments showed a dependence on the particular type of microorganism, these solutions based on natural compounds can be deemed as a promising tool for control of tree diseases.

Fusarium circinatum is a harmful pathogenic fungus mostly attacking Pinus species and also
Pseudotsuga menziesii, causing cankers in trees of all ages, damping-of in seedlings, and mortality in
cuttings and mother plants for clonal production. This fungus is listed as a quarantine pest in several
parts of the world and the trade of potentially contaminated pine material such as cuttings, seedlings or
seeds is restricted in order to prevent its spread to disease-free areas. Inspection of plant material often
relies on DNA testing and several conventional or real-time PCR based tests targeting F. circinatum are
available in the literature. In this work, an international collaborative study joined 23 partners to assess
the transferability and the performance of nine molecular protocols, using a wide panel of DNA from 71
representative strains of F. circinatum and related Fusarium species. Diagnostic sensitivity, specifcity
and accuracy of the nine protocols all reached values >80%, and the diagnostic specifcity was the only
parameter difering signifcantly between protocols.The rates of false positives and of false negatives
were computed and only the false positive rates difered signifcantly, ranging from 3.0% to 17.3%.The
diference between protocols for some ofthe performance values were mainly due to cross-reactions
with DNA from non-target species, which were either not tested or documented in the original articles.
Considering that participating laboratories were free to use their own reagents and equipment, this
study demonstrated that the diagnostic protocols for F. circinatum were not easily transferable to endusers. More generally, our results suggest that the use of protocols using conventional or real-time PCR
outside their initial development and validation conditions should require careful characterization of
the performance data priorto use under modifed conditions (i.e. reagents and equipment). Suggestions
to improve the transfer are proposed.

Aim of the study: To assess the impact on two mycoviruses recently described in F. circinatum mitovirus 1, and 2-2 (FcMV1 and FcMV2-2) on i) mycelial growth, ii) spore germination and iii) relative necrosis.
Material and methods: Fourteen monosporic strains of F. circinatum (one of each pair infected with mycoviruses and the other without them) of the pathogen with and without viruses were selected for the assay. The statistical analysis, were a linear mixed model of analysis of variance considering one between-subjects factor (isolate) and one within-subjects factor with four levels (1=without viruses, 2=only virus FcMV1, 3=only virus FcMV2-2 and 4=both viruses).
Main results: Colony growth rates of F. circinatum isolates were significantly reduced in presence of mycoviruses (p=0.002). The spore germination was also reduced in the F. circinatum isolates containing mycovirus as compared to mycovirus-free isolates (p<0.001). No significant differences in lesion lengths caused by F. circinatum were found in relation to the presence/absence of mycovirus (p<0.61).
Research highlights: Reduction of the percentage of spore germination in the isolates of F. circinatum with mycovirus infections, as compared to free isolates, provides indications of reduction of metabolic activity and plant physiology are discussed. The lack of significant differences found in the length of the lesions caused by F. circinatum with respect to the presence/absence of mycovirus, indicates that further studies with a larger number of variables are required.

Fusarium circinatum is a highly virulent invasive pathogen that causes the disease commonly known as pine pitch canker (PPC). On mature trees, the most common symptoms of PPC include resin bleeding, resinous cankers, wilting of
needles and dieback. In nurseries the main symptoms are yellowish needles, and wilting of foliage and shoots. PPC is
considered one of the most important diseases of conifers globally and at least 60 species of Pinus along with Pseudotsuga menziesii are known to be susceptible. Quarantine regulations are crucial to minimize the risk of new introductions into disease-free countries. However, if these measures fail, implementation of environmentally friendly control
methods is currently encouraged in an integrated management approach that minimizes the use of chemicals in forests.
This review therefore summarizes current knowledge of biological control using endophytic fungi, bacteria and viruses,
and other environmentally friendly methods to control PPC, including thermotherapy, natural products with fungicidal
effects, promoters of innate host resistance mechanisms and breeding for resistance. Key research gaps to be addressed
for improvement of effective management of this disease are discussed.

Fifteen families of mycoviruses have been described and 80% of these catalogued. However, their evolutionary relationship with fungi is not clear. The mycovirus genome can be formed by single- or double-stranded RNA or single-stranded DNA. The effects of mycoviruses range from the induction of a cryptic state (asymptomatic) to promotion of hyper- or hypovirulence in the host. Horizontal transmission of mycoviruses is determined by the presence of different vegetative compatibility types and mating types. Biocontrol of chestnut blight (Cryphonectria parasitica) has been found to be a successful mycovirus-based treatment and is considered a model in forest disease management. Development of this type of biological control tool for use in other forest pathologies requires a sound knowledge of viral symptomatology and transmission. The present review focuses on the application of mycoviruses and the prospects for future use in the biological control of forest diseases as well as on advances in mycovirus-applied research in forestry, landscape and culture of woody plants.

Laccase enzymes (benzenediol: oxygen oxidoreductase, EC 1.10.3.2) play a major role in the degradation of phenolic compounds such as lignin. They are common in fungi and have been suggested to participate in host colonization by pathogenic fungi. Putative mycoviruses have recently been isolated from the causal agent of pine pitch canker disease, Fusarium circinatum Nirenberg & O'Donell. In this study, the effects of single and double mycoviral infections on laccase activity, growth rate and pathogenicity were investigated in fourteen F. circinatum strains. Extracellular laccase activity was analyzed by the Bavendamm test, image processing and a spectrophotometric method. Mycelial growth, in vivo pathogenicity and seedling survival probability were also determined in Monterrey pine (Pinus radiata D. Don) seedlings. The findings showed that (i) mycelial growth of isolates from the same fungal population was homogeneous, (ii) the presence of mycovirus appears to increase the virulence of fungal isolates, (iii) co-infection (with two mycoviruses) caused cryptic effects in fungal isolates, and (iv) laccases embody a possible auxiliary tool in fungal infection. The prospects for biocontrol, the adaptive role of F. circinatum mycoviruses and the importance of laccase enzymes in host colonization are discussed.

The assessment of forest productivity at early stages of stand developmentmay help to define the most appropriate silviculture treatment to be appliedfor each stand. Site index (dominant height at a reference age) is a useful toolfor forest productivity estimation. The aim of this study was to develop amodel to predict site index for Scots pine (Pinus sylvestris L.) plantations innorthern Spain acidic plateau by using soil (physical, chemical and biochemi-cal), climatic and physiographic parameters. To meet this objective, data from35 stands classified into three different site quality classes and 63 soil, cli-matic and physiographic parameters were examined in order to develop a dis-criminant model. After selecting 12 discriminant models which were biologi-cally consistent and presented the higher cross-validated rate of correct classi-fication, a model including four parameters (latitude, inorganic Al, porosityand microbial biomass carbon) as predictors was chosen. The discriminantmodel classified 71% of cases correctly and no inferior-quality stands weremisassigned to the highest quality class. Soil and physiographic parametersincluded in the above model are easily obtainable in the field or by simple la-boratory analysis, thus our results can be easily integrated in operationalforestry to determine site qualit

Water deficit and iron deficiency (iron chlorosis) are common environmental stresses that affect grapevine production in the Mediterranean area. Studies on the impact of both stresses, when they act simultaneously, are rare. The main objective of this investigation was to evaluate the combined effects of the incidence of iron chlorosis and the vine water status on quality of Tempranillo wine. For this, 20 non‐irrigated vineyard subzones (10 m × 10 m each), from non‐affected to moderately affected by iron chlorosis, were monitored in the Ribera del Duero area (north‐central Spain) during two consecutive seasons.
Results. Factorial analyses of variance were performed to study the effects of predawn leaf water potential and foliar chlorophyll content, both measured at veraison, on chemical and sensory characteristics of wine. With an impact much greater than water status, the incidence of iron stress decreased pH of the wine and enhanced sensory attributes as tonality, layer intensity, flavour intensity, and persistence in the mouth. There were increases in red colour, astringency, and persistence of the wine associated with chlorosis, although they might be restricted in water‐deficit conditions.
Conclusion. The results have demonstrated that mild to moderate iron stress can have positive effects on chemical and sensory attributes of Tempranillo wine. Measurements of foliar chlorophyll content at veraison could be very useful to map quality potential in rainfed vineyards affected by iron deficiency.

The Dry Afromontane forests in Northern Ethiopia have been cleared for agriculture and reduced to small and isolated fragments. Most of these forests are located around church territories and are they called church forests. The church forests are known to be biodiversity islands and provide key ecosystem services to local communities. However, to date, the fungal resources of these forests have not been assessed and, therefore, the contribution of fungi to their conservation value is unknown. In 2019, we investigated the fungal diversity of three Dry Afromontane church forests. In each forest, we established nine permanent plots (2 m × 50 m), which were surveyed weekly during the rainy season to quantify the fungal diversity and sporocarp production levels. Explanatory variables were also analyzed to determine their relationship with macrofungal species composition. We collected 13,736 sporocarps corresponding to 188 taxa. Of these, 81% were saprotrophic and 14% were ectomycorrhizal. Sixty-eight species were edible, including economically valuable species such as Tricholoma and Termitomyces. This suggests that these fragmented forest systems could be managed to provide valuable non-timber forest products such as mushrooms and socioeconomic benefits for local communities. Although many species were present in all three forests, some were only found in one forest, highlighting the importance of conserving individual forests. The correlation of the Shannon diversity indices of the two communities showed a positive trend in spite of the lack of correlation between their richness. Macrofungal communities as a whole were influenced by edaphic, spatial and climate variables. This study indicates that church forests support a wide diversity of fungi, including potentially novel fungal species, and highlights the need for forest managers to consider the importance of fungi in forest ecosystem management and to provide habitats that will maintain fungal diversity and sporocarp production when planning conservation strategies.

Wildfire is a recurrent factor that shapes and influences Mediterranean ecosystems where mixed oak (Quercus) forests with a rockrose (Cistus) understory are broadly represented. These ecosystems are also associated with large and diverse fungal communities. These fungal communities play essential ecological roles for the survival of vascular plant, such as the mineral and water uptaking or resistance against pathogens carried out by mycorrhizal fungi, as the saprotrophic fungi are a key factor for the recycling of the dead matter. In addition, edible fungi, such as Boletus edulis, provide a source of income for the nearby rural population. Fuel reduction treatments are applied to reduce the risk of wildfire; however, their potential impact on fungal communities is unclear. Thus, the aim of this work was to investigate the effect of different fuel reduction treatments on fungi associated with Quercus and Cistus. This aim is accompanied by the management-driven objective to obtain data from fuel reduction treatments that will enable managers to find solutions with a balanced approach to maintaining productive areas of edible mushroom production while reducing fire risks across the landscape. Sporocarps were sampled over a five-year period in stands dominated by mature or coppiced Quercus pyrenaica and accompanied by Cistus ladanifer understory. These stands had been subjected to different fuel reduction treatment levels involving moderate- or high-intensity thinning, for Q. pyrenaica, or clearing, for C. ladanifer. The goal was to determine sporocarp production, species richness, and taxonomic composition. Sporocarp production and fungal richness were drastically affected by the fuel reduction treatments but only when C. ladanifer is included in the treatment. Taxa composition was strongly correlated with the treatments applied to the rockrose understory. This was probably due to the large range of associated ectomycorrhizal fungi of C. ladanifer and their high capacity to recolonize an area after disturbances. Based on our results, we conclude that the implementation of moderate-/high-intensity fuel reduction treatments is compatible with the conservation of the fungal community present in these systems. In addition, the creation of a multi-stage mosaic of stands through mechanical management could enable fire prevention to be managed in an effective way while maintaining fungal diversity and sporocarp production, favoring the use of non-wood resources in rural areas and conserving a healthier forest ecosystem.

Quercus pyrenaica-dominated forests are very widely distributed in Mediterranean ecosystems. Traditional forest use, such as coppicing to obtain firewood or livestock grazing under silvopastoral systems, and the current social abandonment of the rural environment have given rise to forest structures of different ages and at different stages of development. Thus, on the one hand, there are large areas of Q. pyrenaica coppice systems that produce a large amount of biomass that have a very high risk of driving forest fires. On the other hand, dehesas, which have very low tree density and are composed of very old trees that are susceptible to different types of environmental stress and have serious regeneration problems and a weak phytosanitary status. In addition, previous studies have suggested that the production of economically valuable edible mushrooms is negatively impacted by silvicultural management. To determine the effects of land management on these ecosystems, we analyzed the soil fungal communities associated with coppice stands (i.e., high-density coppice), high forest stands (i.e., low-density coppice that received silvicultural management 15 years ago to reduce the risk of wildfire), and old stands (i.e., dehesas) to assess their potential ecological roles in their conservation and the diversity of edible mushrooms. We also analyzed the edaphic variables associated with these systems (carbon, pH and the carbon/nitrogen ratio) to understand the dynamics of these fungal communities. We observed two distinguishable communities: pathogen-, parasite-, and endophyte-dominated dehesas and saprotroph- and ectomycorrhizal (ECM)-dominated coppice stands, with a mixed composition in high forest stands. ECM fungi correlated with stand age and structure, showing higher richness levels in high forest stands, particularly ECM fungi with short hyphal exploration type. Finally, the influence of stand age and structure due to land management significantly affected the variety of some edible genera, such as Boletus, Tuber or Terfezia.

In the context of global change, wildfires are not only a threat but are also increasing in their severity in forest ecosystems worldwide, affecting and modifying vegetation, wildlife, and fungal dynamics. Mediterranean ecosystems are frequently affected by fire and prescribed burning is being increasingly used as a tool to reduce the risk and severity of wildfires. Although some of the effects of prescribed burning have been studied, the best moment to perform a prescribed burn to reduce the impact of fire on fungal communities has not been fully investigated. In this study, we analysed the effect of prescribed burning in two different seasons (spring and autumn) on soil fungi associated with natural Pinus nigra forests. Four years after prescribed burning was applied, our analyses showed that the total fungal richness and the composition of fungal communities in spring-burned, autumn-burned, and unburned control plots did not differ significantly. However, analyses of specific phyla and functional trophic groups did reveal some significant differences between spring- or autumn-burned plots and unburned control plots. Valuable edible fungi, which were not affected by the prescribed burning, were also found in the study area. Thus, our results suggest that prescribed burning is not only an interesting tool that could be used to reduce the risk of wildfire but also is compatible with the conservation of fungal communities, and could even promote specific valuable edible species, generating complementary incomes for the rural population. Although further studies are needed, our analyses suggest that the season (spring or autumn) in which prescribed burning is performed does not affect fungal conservation and, therefore, does not need to be one of the factors taken into consideration when selecting the most appropriate time to perform a prescribed burning.

This study aimed to provide baseline information about wild edible tree species (WETs) through surveying of different ethnic groups in dryland areas in Ethiopia. Here the data about WETs are scant, and WETs status is unexplained under the rampant habitat degradation. Use forms, plant parts used, status, ethnobotanical knowledge, conservation needs as well as those threats affecting WETs were reviewed. The study identified 88 indigenous wild edible plants, of which 52 species were WETs. In most cases, fruits were found as the dominant use part, and they were used as raw but were occasionally cooked and preserved. Roots and bark uses are also reported from Ximenia americana and Racosperma melanoxylon respectively. June, July and August were critical periods observed for food shortage in most of the regions. However, in the Gambella region, food shortages occurred in most months of the year. The respondents in this region suggested that WETs could potentially provide them with enough food to make up for the shortage of food from conventional agricultural crops. From the respondents’ perception, Opuntia ficus-indica, Carissa edulis and Ficus vasta were among the most difficult to locate species, and they also received the highest conservation attention. Because of the variety of WETs and existing different threats, a management strategy is required for future conservation, as WETs are vital for the livelihood of local communities and are also necessary to devise a food security strategy for Ethiopia. The lesson obtained could also be useful in other dryland parts in developing countries with similar contexts.

Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae), commonly known as western conifer seed bug (WCSB), is an invasive pest in the Mediterranean, where it has been associated with the decline of Pinus pinea L. kernel production. A biological control of WCSB populations with native egg parasitoids may reduce economic losses. With the purpose to obtaining egg masses laid in situ bags with WCSB, adults were placed, for three consecutive years, in a clone bank, and for 1 year, in a pine forest in Central Spain. To estimate the impact of the parasitoid species on the WCSB population, four parasitism indexes were calculated. The WCSB activity period was estimated for two consecutive years in the clone bank through visual monitoring. Two native parasitoid species were found on the WCSB eggs: Ooencyrtus pityocampae (Mercet) (Hymenoptera: Encyrtidae) and Ooencyrtus obscurus (Mercet) (Hymenoptera: Encyrtidae). The latter parasitoid species represents a new finding for WCSB eggs. In the clone bank, discovery efficiency of the egg masses, parasitism rate of the eggs, impact on host population and exploitation efficiency of the egg masses were significantly higher for O. obscurus than for O. pityocampae. In the pine forest, parasitism index values were also higher for O. obscurus, but significant differences were not found by species. Ooencyrtus obscurus reduced the WCSB population by 6.2%, down to 19.6%, while O. pityocampae reduced it by 1.0%, down to 11.5%. Predated eggs were recorded in both experimental sites in low amounts. Both native parasitoid species could be proposed as biological control agents (BCA) in a biological control programme (BCP) in Europe after measuring their effectiveness with laboratory assessments.

The truffle-plantation «Los Quejigares» was planted in 1971 by AROTZ-CATESA company. It is a 600 ha plot of Quercus ilexmycorrhizated with Tuber melanosporum at 1,250 m a.s.l. on calcareous soil. This plantation is the largest of the world and one of the eldest truffle-plantations of Spain and it is in full production. Knowledge of the mycorrhizal status of a mature black truffle plantation is significant for the improvement of truffle cultivation. Ectomycorrhizae were studied for knowing T. melanosporum persistence and diversity and abundance of other ectomycorrhizal types. Roots of 16 holmoaks
were sampled, 12 trees produce truffle sporocarps and four did not. It was found a mean of about 35% of T. melanosporum ectomycorrhizae in the studied trees, being this significantly higher in the productive trees. Also, 105 more different ectomycorrhizal types were found. In spite of the high number of morphotypes found, it seems that they do not replace T. melanosporum, showing that there is a coexistence between species in the fungal community associated to the roots.
La plantación trufera «Los Quejigares» fue establecida en 1971 por la empresa AROTZ-CATESA. Es una parcela de 600 ha de plantas de Quercus ilex micorrizadas con Tuber melanosporum, que está situada a 1.250 m de altitud sobre suelo calizo. Esta plantación es la más grande del mundo, además de una de las más antiguas de España, y se encuentra en plena producción de trufa negra. El conocimiento del estado micorrícico de las plantaciones truferas maduras es importante para mejorar las técnicas aplicadas en la truficultura. El objetivo de este trabajo es conocer la persistencia de T. melanosporum y la diversidad y abundancia de otras ectomicorrizas que conviven con esta especie. Se muestrearon las raíces de 16 encinas, de las que 12 producían carpóforos de trufa y cuatro no. El porcentaje medio de micorrización por T. melanosporum en los árboles estudiados fue del 35%, éste porcentaje fue significativamente más alto en los árboles productores. Además, se encontraron 105 tipos de ectomicorrizas. A pesar del alto número de morfotipos encontrados, parece que éstos no producen el desplazamiento de T. melanosporum, mostrando que es posible la coexistencia entre diferentes especies pertenecientes a la comunidad de hongos asociadas a las raíces de los árboles.

Agriculture nowadays is facing many challenges, with among the most important to be able to feed the increasing human population through more sustainable and environmentally friendly production. In this context, the use of microorganisms has been extensively studied, both with fungi such as Trichoderma spp. and with bacteria, such as Bacillus spp. or Pseudomonas spp. While inoculation with these microorganisms has a positive effect on crops, their combination offers even greater potential as plant growth promoters and as biocontrol agents, with diverse mechanisms that are thoroughly considered in this review. Synergies between Trichoderma and bacteria cause more benefits than the sum of their parts, and this makes them a promising alternative for managing crops and controlling diseases or pests in modern agriculture. However, more studies are needed to determine the specific mechanisms of this synergistic effect in certain lines of research, since there is extensive data about their use as plant growth promoters or biocontrol agents against diseases and certain pests, but little or no information is available about their use against diseases caused by viruses or the effect on plant tolerance to abiotic stresses.

Mycoviruses are known to be difficult to cure in fungi but their spontaneous loss occurs commonly. The unexpected disappearance of mycoviruses can be explained by diverse reasons, from methodological procedures to biological events such as posttranscriptional silencing machinery. The long-term effects of a virus infection on the host organism have been well studied in the case of human viruses; however, the possible residual effect on a fungus after the degradation of a mycovirus is unknown. For that, this study analyses a possible residual effect on the transcriptome of the pathogenic fungus Fusarium circinatum after the loss of the mitovirus FcMV1. The mycovirus that previously infected the fungal isolate was not recovered after a 4-year storage period. Only 14 genes were determined as differentially expressed and were related to cell cycle regulation and amino acid metabolism. The results showed a slight acceleration in the metabolism of the host that had lost the mycovirus by the upregulation of the genes involved in essential functions for fungal development. The analysis also revealed a weak expression in the annotated genes of the RNA silencing machinery. To our knowledge, this is the first time that a potential residual effect on the host transcriptome caused by the past infection of a mycovirus is reported.

Ethnomycological information was gathered by conducting semi-structured interviews with members of the Amhara, Agew, and Sidama ethnic groups in Ethiopia. A total of 300 individuals were involved in this study. Forest excursions were also undertaken to investigate the habitat and to identify useful wild mushroom species present in the study areas. A total of 24 useful wild mushroom species were identified. Among the three ethnic groups, the Sidama have the most extensive ethnomycological knowledge and over seven vernacular names for useful fungal species were recorded for this group. Collecting mushrooms is common practice among the Sidama and usually carried out by women and children during the main rainy season from June to September. Useful mushrooms are collected in natural forests, plantation forests, grazing areas, home gardens, and swampy areas. In terms of medicinal uses, Lycoperdon perlatum Pers. and Calvatia rubroflava (Cragin) Lloyd. are well-known treatments for wounds and skin disease. Harvest storage of wild mushroom species is unknown. Respondents in the Amhara and Agew ethnic groups were similar in terms of their use and knowledge of mushrooms. Both ethnic groups reported that although wild mushroom species were consumed by their grandparents, they do not eat mushrooms themselves, which could eventually represent a loss of mycological knowledge in these two ethnic groups. Such inconsistency between ethnic groups in terms of their knowledge may also be linked to the social valuation of mushroom resources, which could easily be mitigated by raising awareness. Thus, the baseline information obtained in this study could be useful for further investigations and documentation, and to promote ethnomycological benefits to different ethnic groups in countries with similar settings.

Research Highlights: Litterfall biomass after prescribed burning (PB) is significantly influenced by meteorological variables, stand characteristics, and the fire prescription. Some of the fire-adaptive traits of the species under study (Pinus nigra and Pinus pinaster) mitigate the effects of PB on litterfall biomass. The Bayesian approach, tested here for the first time, was shown to be useful for analyzing the complex combination of variables influencing the effect of PB on litterfall. Background and Objectives: The aims of the study focused on explaining the influence of meteorological conditions after PB on litterfall biomass, to explore the potential influence of stand characteristic and tree traits that influence fire protection, and to assess the influence of fire prescription and fire behavior. Materials and Methods: An experimental factorial design including three treatments (control, spring, and autumn burning), each with three replicates, was established at two experimental sites (N = 18; 50 × 50 m2 plots). The methodology of the International Co-operative Program on Assessment and Monitoring of Air Pollution Effects on Forests (ICP forests) was applied and a Bayesian approach was used to construct a generalized linear mixed model. Results: Litterfall was mainly affected by the meteorological variables and also by the type of stand and the treatment. The effects of minimum bark thickness and the height of the first live branch were random. The maximum scorch height was not high enough to affect the litterfall. Time during which the temperature exceeded 60 °C (cambium and bark) did not have an important effect. Conclusions: Our findings demonstrated that meteorological conditions were the most significant variables affecting litterfall biomass, with snowy and stormy days having important effects. Significant effects of stand characteristics (mixed and pure stand) and fire prescription regime (spring and autumn PB) were shown. The trees were completely protected by a combination of low-intensity PB and fire-adaptive tree traits, which prevent direct and indirect effects on litterfall. Identification of important variables can help to improve PB and reduce the vulnerability of stands managed by this method.

This study is conducted in the short-rotation plantations from the Afromontane Region of Ethiopia. Sporocarps were sampled weekly in a set of permanent plots (100 m2) in young, medium-aged, and mature Pinus radiata (Don) plantations. Fungal richness, diversity, and sporocarp yields were estimated. Composite soil samples were also collected from each plot to determine explanatory edaphic variables for taxa composition. We collected 92 fungal taxa, of which 8% were ectomycorrhizal (ECM). Taxa richness, the Shannon diversity index, and ECM species richness were higher in mature stands. Interestingly, 26% of taxa were classified as edible. Sporocarp yield showed increasing trends towards matured stands. OM and C/N ratio significantly affected fungal composition and sporocarp production. The deliberate retention of mature trees in a patch form rather than clear felling of the plantations could be useful to conserve and promote fungal diversity and production, including valuable taxa such as Morchella, Suillus, and Tylopilus in older stands. This approach has important implications for forest floor microhabitats, which are important for macrofungal occurrence and production. Thus, this strategy could improve the economic outputs of these plantations in the Afromontane Region, while the mature trees could serve as a bridge for providing fungal inocula to the new plantations.

In this study, we evaluated stand status, dendrometric variables, and fruit production of Tamarind (Tamarindus indica L.) trees growing in bushland and farmland-use types in dryland areas of Ethiopia. The vegetation survey was conducted using the point-centered quarter method. The fruit yield of 54 trees was also evaluated. Tree density and fruit production in ha were estimated. There was a significant difference in Tamarind tree density between the two land-use types (p = 0.01). The mean fruit yield of farmland trees was significantly higher than that of bushland trees. However, Tamarind has unsustainable structure on farmlands. Differences in the dendrometric characteristics of trees were also observed between the two land-use types. Predictive models were selected for Tamarind fruit yield estimations in both land-use types. Although the majority of farmland trees produced <5000 fruit year−1, the selection of Tamarind germplasm in its natural ranges could improve production. Thus, the development of management plans to establish stands that have a more balanced diameter structure and thereby ensure continuity of the population and fruit yields is required in this area, particularly in the farmlands. This baseline information could assist elsewhere in areas that are facing similar challenges for the species due to land-use change.

Fusarium circinatum causes one of the most important diseases of conifers worldwide, the pine pitch canker (PPC). However, no effective field intervention measures aiming to control or eradicate PPC are available. Due to the variation in host genetic resistance, the development of resistant varieties is postulated as a viable and promising strategy. By using an integrated approach, this study aimed to identify differences in the molecular responses and physiological traits of the highly susceptible Pinus radiata and the highly resistant Pinus pinea to F. circinatum at an early stage of infection. Dual RNA-Seq analysis also allowed to evaluate pathogen behavior when infecting each pine species. No significant changes in the physiological analysis were found upon pathogen infection, although transcriptional reprogramming was observed mainly in the resistant species. The transcriptome profiling of P. pinea revealed an early perception of the pathogen infection together with a strong and coordinated defense activation through the reinforcement and lignification of the cell wall, the antioxidant activity, the induction of PR genes, and the biosynthesis of defense hormones. On the contrary, P. radiata had a weaker response, possibly due to impaired perception of the fungal infection that led to a reduced downstream defense signaling. Fusarium circinatum showed a different transcriptomic profile depending on the pine species being infected. While in P. pinea, the pathogen focused on the degradation of plant cell walls, active uptake of the plant nutrients was showed in P. radiata. These findings present useful knowledge for the development of breeding programs to manage PPC.

The diameter distributions of trees in 50 temporary sample plots (TSPs) established in Pinus halepensis Mill. stands were recovered from LiDAR metrics by using six probability density functions (PDFs): the Weibull (2P and 3P), Johnson’s SB, beta, generalized beta and gamma-2P functions. The parameters were recovered from the first and the second moments of the distributions (mean and variance, respectively) by using parameter recovery models (PRM). Linear models were used to predict both moments from LiDAR data. In recovering the functions, the location parameters of the distributions were predetermined as the minimum diameter inventoried, and scale parameters were established as the maximum diameters predicted from LiDAR metrics. The Kolmogorov–Smirnov (KS) statistic (Dn), number of acceptances by the KS test, the Cramér von Misses (W2) statistic, bias and mean square error (MSE) were used to evaluate the goodness of fits. The fits for the six recovered functions were compared with the fits to all measured data from 58 TSPs (LiDAR metrics could only be extracted from 50 of the plots). In the fitting phase, the location parameters were fixed at a suitable value determined according to the forestry literature (0.75·dmin). The linear models used to recover the two moments of the distributions and the maximum diameters determined from LiDAR data were accurate, with R2 values of 0.750, 0.724 and 0.873 for dg, dmed and dmax. Reasonable results were obtained with all six recovered functions. The goodness-of-fit statistics indicated that the beta function was the most accurate, followed by the generalized beta function. The Weibull-3P function provided the poorest fits and the Weibull-2P and Johnson’s SB also yielded poor fits to the data.

RNA-based strategies for plant disease management offer an attractive alternative to agrochemicals that negatively impact human and ecosystem health and lead to pathogen resistance. There has been recent interest in using mycoviruses for fungal disease control after it was discovered that some cause hypovirulence in fungal pathogens, which refers to a decline in the ability of a pathogen to cause disease. Cryphonectria parasitica, the causal agent of chestnut blight, has set an ideal model of management through the release of hypovirulent strains. However, mycovirus-based management of plant diseases is still restricted by limited approaches to search for viruses causing hypovirulence and the lack of protocols allowing effective and systemic virus infection in pathogens. RNA interference (RNAi), the eukaryotic cell system that recognizes RNA sequences and specifically degrades them, represents a promising. RNA-based disease management method. The natural occurrence of cross-kingdom RNAi provides a basis for host-induced gene silencing, while the ability of most pathogens to uptake exogenous small RNAs enables the use of spray-induced gene silencing techniques. This review describes the mechanisms behind and the potential of two RNA-based strategies, mycoviruses and RNAi, for plant disease management. Successful applications are discussed, as well as the research gaps and limitations that remain to be addressed.

Ethiopian forests are rich in valuable types of non-wood forest products, including mushrooms. However, despite their nutritional, economic, and ecological importance, wild edible mushrooms have been given little attention and are rarely documented in Ethiopia. In this study, we assessed mushroom production levels in natural and plantation forests and the influence of climate and environmental variables on mushroom production. Sporocarps were sampled weekly from July to August 2019 at a set of permanent plots (100 m2) in both forest systems. We analyzed 63 plots to quantify sporocarp species’ richness and fresh weight as well as to elucidate the degree of influence of forest types and site conditions, including soil and climate. Morphological analyses were used to identify fungi. In total, we recorded 64 wild edible fungal species belonging to 31 genera and 21 families from the plots established in the natural and plantation forests. A significantly greater total number of edible fungi were collected from natural forests (n = 40 species) than from plantations. Saprotrophs (92.19%) were the dominant guild whereas ectomycorrhizal fungi represented only 6.25% of species. Ecologically and economically important fungal species such as Agaricus campestroides, Tylopilus niger, Suillus luteus, Tricholoma portentosum, and Morchella americana were collected. The sporocarp yield obtained from plantation forests (2097.57 kg ha−1 yr–1) was significantly greater than that obtained from natural forests (731.18 kg ha−1 yr–1). The fungal community composition based on sporocarp production was mainly correlated with the organic matter, available phosphorus, and total nitrogen content of the soil, and with the daily minimum temperature during collection. Accordingly, improving edible species’ richness and sporocarp production by maintaining ecosystem integrity represents a way of adding economic value to forests and maintaining biological diversity, while providing wood and non-wood forest products; we propose that this approach is imperative for managing Ethiopian forests.

Fungal endophytes have been found to protect their hosts against multiple fungal pathogens. Frequently, the secondary metabolites produced by the endophyte are responsible for antifungal activity. To develop new bio-products that are more environmentally friendly than synthetic pesticides against Phytophthora cinnamomi, a serious pathogen of many plant species, the antifungal activity of filtrates or extracts from four endophytes was evaluated in different in vitro tests and in plants of Lupinus luteus. In the dual culture assays, the filtrate of one of the endophytes (Drechslera biseptata) completely inhibited the mycelial growth of the pathogen. Moreover, it showed a very low minimal inhibitory concentration (MIC). Epicoccum nigrum, an endophyte that also showed high inhibitory activity and a low MIC against P. cinnamomi in those two experiments, provided a clear growth promotion effect when the extracts were applied to L. luteus seedlings. The extract of Fusarium avenaceum also manifested such a promotion effect and was the most effective in reducing the disease severity caused by the pathogen in lupine plants (73% reduction). Results demonstrated the inhibitory activity of the filtrates or extracts of these endophytes against P. cinnamomi. A better insight into the mechanisms involved may be gained by isolating and identifying the metabolites conferring this inhibitory effect against this oomycete pathogen.

Future climate predictions for the Mediterranean area include prolonged droughts and an increase in the frequency of extreme events. Silvicultural modification of stand density can buffer the response of tree growth to changes in climate by enhancing soil water availability. We analyzed the stem growth dynamics of Pinus halepensis, including the days of the year when 25%, 50% and 75% of the intra-annual basal growth was achieved, considering two different social statuses (suppressed and dominant) under four different thinning intensities (15%, 30% and 45% removal of the basal area) for 8 years, based on biweekly band dendrometer recordings. The moment the trees reached 25% of the intra-annual basal growth was significantly influenced by the amount of precipitation accumulated during the previous winter. On the other hand, the moment the trees reached 75% of the intra-annual basal growth was significantly influenced by water availability in a shorter term, which also affected the length of the growing period. Modification of competition through thinning showed a significantly positive impact on growth, causing a delayed attainment of 50% of the intra-annual basal growth. These results imply valuable information about forest dynamics that will support forest managers’ decisions dealing with low water-availability in forests.

Scots pine (Pinus sylvestris) and Stone pine (Pinus pinea) are two important species used in re-forestation that are subject to damage by damping-off fungi in forest nurs-eries. Twenty-two isolates of Fusarium oxysporum and F. verticillioides from diseased seedlings of eight different hosts were tested for aggressiveness on seeds and seed-lings of both pine species, including the effects on seedling emergence and mortal-ity. Scots pine was more susceptible to damping-off than Stone pine, as indicated both by reduced seedling emergence and elevated seedling mortality. The impact of F. oxysporum and F. verticillioides on seeds and seedlings did not differ significantly for either pine species. Our findings support previous studies that found that these are damping-off pathogens on the studied pines. Whereas most isolates proved to be pathogenic, some isolates of both Fusarium species showed to be non- pathogenic.

The use of mobile laser scanning to survey forest ecosystems is a promising, scalable technology to describe the 3D structure of forests at a high resolution. We use a structurally complex, mixed-species Mediterranean forest to test the performance of a mobile Handheld Laser Scanning (HLS) system to estimate tree attributes within a forest patch in central Spain. We describe the different stages of the HLS approach: field position, ground data collection, scanning path design, point cloud processing, alignment between detected trees and measured reference trees, and finally, the assessment of main tree structural attributes diameter at breast height (DBH) and tree height considering species and tree size as control factors. We surveyed 418 reference trees to account for omission and commission error rates over a 1 ha plot divided into 16 sections and scanned using two different scanning paths. The HLS-based approach reached a high of 88 and 92% tree detection rate for the best combination of scanning path and point cloud processing modes for the HLS system. The root mean squared errors for DBH estimates varied between species: errors for Pinus pinaster were below 2 cm for Scan 02. Quercus pyrenaica, and Alnus glutinosa showed higher error rates. We observed good agreement between ALS and HLS estimates for tree height, highlighting differences to field measurements. Despite the complexity of the mixed forest area surveyed, our results show that HLS is highly efficient at detecting tree locations, estimating DBH, and supporting tree height measurements as confirmed with airborne laser data used for validation. This study is one of the first HLS-based studies conducted in the Mediterranean mixed forest region, where variability in tree allometries and spacing and the presence of natural regeneration pose challenges for the HLS approach. HLS is a feasible, time-efficient, scalable technology for tree mapping in mixed forests with potential to support forest monitoring programmes such as national forest inventories lacking three-dimensional, remote sensing data to support field measurements.

Endophytic fungi have been found to produce a wide range of extracellular enzymes, which are increasingly in demand for their industrial applications. Different by-products from the agrifood industry could be used as fungal growth substrates for the massive production of these enzymes, specifically as a way to revalorize them. However, such by-products often present unfavorable conditions for the microorganism’s growth, such as high salt concentrations. Therefore, the objective of the present study was to evaluate the potential of eleven endophytic fungi—which were isolated from plants growing in a harsh environment, specifically, from the Spanish dehesas—for the purposes of the in vitro production of six enzymes (i.e., amylase, lipase, protease, cellulase, pectinase and laccase) under both standard and salt-amended conditions. Under standard conditions, the studied endophytes produced between two and four of the six enzymes evaluated. In most of the producer fungal species, this enzymatic activity was relatively maintained when NaCl was added to the medium. Among the isolates evaluated, Sarocladium terricola (E025), Acremonium implicatum (E178), Microdiplodia hawaiiensis (E198), and an unidentified species (E586) were the most suitable candidates for the massive production of enzymes by using growth substrates with saline properties (such as those found in the many by-products from the agrifood industry). This study should be considered an initial approach by which to further study the identification of these compounds as well as to develop the optimization of their production by directly using those residues.

This article develops an economic model that compares the option of replacement planting to maintain target density with the option of enhancing seedling survival from the beginning by applying irrigation. The model we develop uses variables common in forestry practice and yields the threshold value of seedling failure at which both alternatives offer the same economic result based on a comparative analysis of costs and benefits. By comparing this threshold with the level of seedling failure expected for an afforestation in the absence of irrigation, the planner can make an informed decision between both alternatives. The model has been applied to thirteen practical cases covering a wide range of plantations with different density, purpose and average annual net income. Based on the results obtained, a k-means clustering is carried out to identify five groups according to their suitability for irrigation. The sensitivity of the model's input variables in respect to the threshold of seedling failure is also analized. Irrigation is profitable when the expected level of seedling failure is high and/or the value of the threshold decision is low. The latter is usually the case at afforestations that require a low acceptable level of seedling failure and/or in productive plantation forestry.

Fusarium circinatum, a fungus that causes pitch canker disease, has been present in Europe
since at least 2003, when it was detected in northern Spain and found to be producing severe
damage in tree nurseries and pine plantations. In this study, we tested a method of biological
control of the disease with Trichoderma viride, a fungal species successfully used against
many other pathogens. In vitro and in vivo assays were carried out to test the efficacy of this
antagonist in controlling F. circinatum. The T. viride isolate exerted a significant effect on the
growth of F. circinatum in the in vitro assay, reducing the length of the pathogen colony by
half. However, although we tested three different concentrations of the T. viride spore solution,
no clear conclusions were obtained with regard to the effects on the Pinus radiata seedlings.
To our knowledge, this is the first study carried out with the aim of using Trichoderma spp.
to control pitch canker disease.

Leptoglossus occidentalis Heidemann (Hemiptera: Coreidae), known as the western conifer seed bug (WCSB), is
a significant pest of the Pinus pinea L. kernel sector in the Mediterranean basin. The egg parasitoid species
Ooencyrtus obscurus (Mercet) (Hymenoptera: Encyrtidae) has been recently recorded on WCSB eggs in Central
Spain. This study defines the influence of the egg cluster size on the parasitism rate of O. obscurus, its reproductive
and demographic parameters with the goal of defining the potential of this species to be a biological control
agent. Ooencyrtus obscurus is weakly synovigenic, with the parasitism period concentrating in the first two
weeks, reaching its maximum level of intensity on the 1st day (30.2 %). The mean oviposition period was
2.3 days, with the mean female longevity being 16.9 days. The mean rate of pre-imaginal survival was high
(96.7 %), with the mean pre-imaginal development time being significantly higher for females than for males.
The sex ratio (% females) was 41.2 %, while the reproductive strategy was defined as being pseudoarrhenotokous
parthenogenesis after comparing mated and unmated female offspring. Regarding demographic
parameters, a single O. obscurus female was able to produce more than 3 female offspring (R0) in a generation
time (T) of 23.96 days, multiply its population 1.05 times a day (λ), and double it in 14.34 days (Td). The
comparison between these results and those established for the main egg parasitoid of the WCSB in its native
area could allow for decisions to be made on the type of biological control program to be applied in Europe.

β-Glucans and soy lecithin were used as encapsulating materials for resveratrol and tebuconazole, in order to test their antifungal activity against Botrytis cinerea. First an oil-in-water emulsion was formed and afterwards the emulsion was dried by spray-drying or by particles from gas saturated solutions-drying (PGSS-drying). β-Glucans were precipitated also by supercritical anti-solvent (SAS), but it was not a suitable drying process for this material. Particles were characterized regarding particle size, morphology, crystallinity, encapsulation efficiency and in vitro activity against B. cinerea. Although the emulsions with β-glucans had bigger droplet size than the ones with lecithin, there was no difference on particle size for each encapsulating material, it was just dependent on the drying process. For all the materials and drying processes, completely amorphous particles were obtained, in spite of the crystalline form of the pure active compounds. Concerning the antifungal activity, the encapsulation of tebuconazole did not improve its action, because it was already very effective. Pristine resveratrol did not reduce fungal growth, but it was inhibited between 50% and 70% with encapsulated resveratrol, which implies the production of an effective fungicide against B. cinerea totally from natural origin substances.

In greenhouse experiments, the ectomycorrhizal fungus Laccaria laccata was evaluated for biological control of preemergence,
post-emergence and late damping-off of Pinus pinea caused by Fusarium verticillioides and F. oxysporum.
In pre-emergence damping-off assays, preinoculation with Laccaria laccata did not significantly improve germination of
seeds and no statistical significant differences were found in Fusarium treatments when compared with controls. At 18
weeks after sowing, inoculation with L. laccata reduced the incidence of post-emergence damping-off but differences were
significant only in F. oxysporum treatments. Pinus pinea transplanted plants were used in late damping off assays, and only
F. oxysporum produced significant damage. Inoculation with L. laccata did not attenuate significantly the virulence of
F. oxysporum. However, the percentage of mycorrhization did not reached significant level, so the amount of mycorrhizal
fungus was insufficient for effective protection. Although very low percentages of mycorrhization were recorded in all
mycorrhized treatments, and Fusarium occurrence significantly reduced mycorrhization, those levels have been efficient to
reduce damage in F. oxysporum post-emergence damping-off assays. In short, pre-emergence damping-off was not found;
only F. oxysporum produced significant damage on P. pinea seedlings and L. laccata reduced damage when the percentage
of mycorrhization reached a significant level. These results have been compared with previous work on P. sylvestris
inoculated with the same mycorrhizae isolate and Fusarium pathogens.

Multiplex 330 (MX) is a portable, non-invasive fluorescence sensor that provides different multiparametric indices that are sensitive to the concentration of chlorophylls, flavonols, and anthocyanins on the leaf surface. This study investigated the use of these indices to assess the variability on free volatile composition of grapes (Vitis vinifera L.) in the field as well as other components of their quality potential in vineyards affected by iron deficiency chlorosis (IDC). Twenty non-irrigated Tempranillo/110 Richter vineyard subzones from non-affected to moderately affected by IDC were monitored in Ribera del Duero area (Spain) during two seasons. The results indicated that MX can characterize the spatial variation of leaf pigment concentrations, agronomic performance, and grape quality in vineyards affected by IDC. The MX indices measured at the leaf level close to harvest had better predictive values for the concentrations of free alcohols, volatile acids, C13-norisoprenoids, esters and acetates in the must than vine vigor, size or degree of technological maturity of the grapes. Our study demonstrates that the MX indices to estimate leaf pigment concentrations can be helpful to assess the technological maturity and free volatile composition of wine grapes in vineyards affected by IDC; nevertheless, the efficacy of the indexes may vary according to the year season.

The scale of opportunity to implement forest restoration exceeds billions of ha worldwide, and a part of this area in northern temperate regions includes formerly oak (Quercus spp.)-dominated ecosystems. The cost of achieving restoration is often high, and tends to increase with severity of ecosystem degradation. Therefore, it is important to develop cost-efficient regeneration practices to support forest restoration. Direct seeding of acorns, one of the earliest artificial forest regeneration techniques developed, offers several benefits including costs that can be about a third of planting oak seedlings. However, direct seeding is presently a more uncertain practice for establishing oak forests and woodlands than is planting seedlings. Much of this uncertainty can be a result of acorn depredation by rodents even though other factors may also limit oak establishment. This review provides a synthesis of foundational knowledge, particularly from Europe and North America, pertaining to the biology and ecology of acorn production, acorn germination, early seedling growth, and acorn depredation by granivorous rodents. We build on this knowledge to review research on operational direct seeding practices and four basic strategies for acorn depredation control (chemical, ecological, physical and silvicultural). We suggest that environmentally sound approaches to minimize acorn depredation and increase seedling establishment currently exists. For example, seeding operations probably hold higher chances for success if scheduled during years of high masting, if applied on open sites (areas with little shrub and tree cover), and if acorn lots are sized and sown at an appropriate depth. Several gaps in our knowledge limit the development of improved operational practices for broader success. We lack information on basic acorn biology and proper handling and storage practices for many of the oaks around the world. And, we need research to support development of new techniques or combinations of strategies and techniques that minimize acorn depredation under a wide range of site conditions. Nevertheless, our synthesis suggests that direct seeding will remain a cost-effective and environmentally sound practice for oak forest and woodland establishment, and it will likely gain expanded use as future research informs innovation that increases seed availability, decreases acorn depredation, and raises predictability of oak seedling establishment.
