La reproducción de la especie ovina se caracteriza por ser estacional. Si bien las razas que se encuentran en el entorno mediterráneo no presentan una estacionalidad muy marcada, lo cierto es que resulta interesante aplicar métodos para inducir y sincronizar celos con el fin de mejorar la prolificidad, fertilidad y fecundidad.
Entre los factores que influyen en la reproducción ovina, se encuentran: el fotoperiodo, la nutrición, el genotipo, la edad, los factores sociales.
Los métodos de control de la reproducción de esta especie, pueden ser naturales (efecto macho, flushing), farmacológicos (progesterona, prostaglandinas, melatonina) o mixtos.
Por último, se muestra una comparativa de diferentes métodos de control y su efecto sobre la fertilidad y la prolificidad.

One of the challenges to continue improving polymeric membranes properties involves the development of novel chemically modified fillers, such as nitrogen-rich 2-D nanomaterials. Graphitic carbon nitride (g-C3N4) has attracted significant interest as a new class of these fillers. Protonation is known to afford it desirable functionalities to form unique architectures for various applications. In the work presented herein, doping of Matrimid® with protonated g-C3N4 to yield Matrimid®/g-C3N4 mixed matrix membranes was found to improve gas separation by enhancing the selectivity for CO2/CH4 by up to 36.9% at 0.5 wt % filler doping. With a view to further enhancing the contribution of g-C3N4 to the performance of the composite membrane, oxygen plasma and hydrazine monohydrate treatments were also assayed as alternatives to protonation. Hydroxylamination by oxygen plasma treatment increased the selectivity for CO2/CH4 by up to 52.2% (at 2 wt % doping) and that for O2/N2 by up to 26.3% (at 0.5 wt % doping). Hydrazination led to lower enhancements in CO2/CH4 separation, by up to 11.4%. This study suggests that chemically-modified g-C3N4 may hold promise as an additive for modifying the surface of Matrimid® and other membranes.

The response of European beech (Fagus sylvatica L.) to climate warming will depend on the ability of their populations to adjust tree performance to water shortage. By exploring inter- and intra-annual variations in secondary growth and mean vessel area (MVA), we assessed the effects of precipitation on cambial activity and hydraulic control during the vessel expansion phase along tree lifes. We sampled beech populations at low and high altitude from four mountain ranges across its southwestern distribution edge. We measured a total of 45,897 rings from 126 trees and 5.5 million vessels from 76 trees. We built chronologies for ring width and MVA between 1950 and 2017, calculated their climate responses and evaluated the effects of region, altitude and chronology type (ring-width vs. MVA) by means of ordinations (PCA) and constrained ordinations (pRDA). Precipitation controlled ring width and MVA along beech's southwestern distribution range, but at different time domains. Ring width responded primarily to summer precipitation during the previous growing season, whereas MVA responded to water availability during the vessel expansion phase, with timing shifting along the ring, according to the moment of vessel expansion. Regional differences were significant, but low, compared with the effect of chronology type. A large part of the variance explained by region was due to the strong difference between Western Pyrenees forests –growing under hyperhumid conditions– and the rest of forests under drier and warmer climate. Only minor differences between altitudes were found for the climate control of ring width and vessel size at annual scale, and no intra-annual effect on climate control of MVA. The stronger effect of chronology type on climatic response compared to the role of geographical location or altitude suggests common climate constraints on secondary growth and xylem anatomy along beech dry edge.

Animal production is one of the largest contributors to ammonia emissions. A project, “Ammonia Trapping”, was designed to recover gaseous ammonia from animal barns in Spain. Laboratory experiments were conducted to select a type of membrane most suitable for gaseous ammonia trapping. Three types of gas-permeable membranes (GPM), all made of expanded polytetrafluoroethylene (ePTFE), but with different diameter (3.0 to 8.6 mm), polymer density (0.45 to 1.09), air permeability (2 to 40 L·min−1·cm2), and porosity (5.6 to 21.8%) were evaluated for their effectiveness to recover gas phase ammonia. The ammonia evolved from a synthetic solution (NH4Cl + NaHCO3 + allylthiourea), and an acidic solution (1 N H2SO4) was used as the ammonia trapping solution. Replicated tests were performed simultaneously during a period of 7 days with a constant flow of acidic solution circulating through the lumen of the tubular membrane. The ammonia recovery yields were higher with the use of membranes of greater diameter and corresponding surface area, but they were not affected by the large differences in material density, porosity, air permeability, and wall thickness in the range evaluated. A higher fluid velocity of the acidic solution significantly increased—approximately 3 times—the mass NH3–N recovered per unit of membrane surface area and time (N-flux), from 1.7 to 5.8 mg N·cm−2·d−1. Therefore, to optimize the effectiveness of GPM system to capture gaseous ammonia, the appropriate velocity of the circulating acidic solution should be an important design consideration.

Understanding the vulnerability of individual trees to climate requires moving from population to individual level. This study evaluates individual tree response in a mixed forest by assessing how size and neighbourhood density modulated growth responses to climate among coexisting tree species. To understand the complete variation in growth responses to climate, it is necessary to consider intrapopulation variability. Trees respond as individual entities, and their response is modulated by their characteristics and neighbourhood context. To assess the individual climate sensitivity, all living Iberian birches, European beeches, and pedunculate oaks trees located in a temperate mixed forest were cored in four 40 m × 40 m plots. Standard ring-width chronologies were built at tree and species level for the 1977–2007 period. Chronologies were related to climatic variables (monthly precipitation, hailstorm and mean temperature, and summer (June–August) precipitation). Growth response to climate varied among species and individual trees. Differences in climate–growth relationship among species could be partially attributed to the different xylem anatomy, since secondary growth of ring-porous pedunculate oak (Quercus robur L.) was mainly dependent on the previous-winter climatic conditions (January temperature), while for the diffuse-porous Iberian birch (Betula celtiberica Rothm. and Vasc.) and European beech (Fagus sylvatica L.), spring temperature and summer precipitation were the major constraining factors of growth. Tree features and identity of neighbourhood modulated climatic response, especially for Iberian birch and pedunculate oak. Dominant trees in less crowded neighbourhoods responded more intensely to climate factors. Understanding the individual variability of growth responses to climate will provide more realistic predictions of forests response to climate change.

Nitrate vulnerable zones (NVZs) are areas considered to be at high risk of water pollution due to an excess of nitrates and, according to European regulations, codes of good agricultural practice are to be implemented by farmers, such as reducing doses of the applied fertilizers, or the use of fertilizers that minimize nitrate leaching. In this work, the influence of organic fertilization with dried pig manure (DPM) as compared to mineral fertilization with ammonium sulfate nitrate with 3,4-dimethylpyrazole phosphate nitrification inhibitor was studied in a barley crop planted in a NVZ in Fompedraza (Valladolid, Spain). Organic and mineral fertilizers were applied at different rates (85, 133 and 170 kg N·ha−1·year−1 vs. 90 and 108 kg N·ha−1·year−1, respectively) over a three-year period, in a randomized complete block design with six treatments and four blocks. DPM-based fertilization resulted in a 65% increase in crop yield as compared to the control soil, reaching 1800 kg·ha−1 for an application rate of 85 kg N·ha−1·year−1. Higher DPM rates were found to increase the electrical conductivity and assimilable phosphorus, potassium, magnesium and organic matter contents, but did not lead to yield enhancements. Final nitrate and ammonium concentrations were lower than 10 mg·kg−1 and 20 mg·kg−1, respectively, and no increase in soil salinity or heavy metal pollution was observed. DPM fertilization should be supplemented with small doses of inorganic fertilizers to obtain crop yields similar to those attained with mineral fertilization.

The relationship between forest structure and plant diversity in Mediterranean Maritime pine stands (Pinus pinaster Ait.) in the Iberian Range (Spain) was studied. Forty eight stands were sampled. In each, a circular plot (15 m radius) and a transect (25*1 m2) were established to estimate stand variables and record presence and abundance of vascular species respectively. Canonical correlation analysis (CCA), simple correlations and multiple stepwise linear regressions were used to explore the relationship between plant diversity and forest structure. Correlation between diversity measurements and stand variables is very weak, but significant correlations were found when evaluating each set of variables separately. Presence and cover of some species (for instance, Veronica arvensis L. or Micropyrum tenellum (L.) Link) is correlated with stand variables; however, determination coefficients found in step-by-step regression are not significant.
En el presente trabajo se ha estudiado la relación entre la estructura forestal y la biodiversidad en rodales de pino negral (Pinus pinaster Ait.) en el Sistema Ibérico, España. En cada uno de los cuarenta ocho rodales muestreados se estableció una parcela circular de radio 15 m y un transecto de 25 por 1 m para estimar diferentes variables dasométricas y anotar la presencia y abundancia de especies de la flora vascular respectivamente. Se utilizaron técnicas de análisis de correlación canónica, correlación simple y regresión lineal múltiple paso a paso para explorar la relación entre la diversidad vascular y la estructura forestal. La correlación entre las medidas de diversidad y las variables del rodal fue débil pero cuando se analizaron cada conjunto de variables de forma independiente se encontraron correlaciones significativas. La presencia y la cobertura de ciertas especies está correlacionada con variables dasométricas pero los coeficientes de determinación de la regresión resultaron no significativos.

Public demand for harvesting wild edible mushrooms has risen in recent decades and currently affects many forested areas around the world. The idea of introducing permits for users has been conceived as a tool for ecosystem management. The problem is that policy-makers lack the necessary means to help guide them when establishing prices for such harvesting permits. Valuing the recreational benefits which mushroom harvesters derive from harvesting wild edible mushrooms may provide certain guidelines as to how much people would be willing to pay and may also justify future payments levied on harvesters. The aim of the present article is to estimate a model for determining citizens’ willingness to pay for a harvesting permit in a forest in Andalusia (Spain) using contingent valuation methods. Results show that mean willingness to pay is 22.61 Euros (USD28.18) per harvester and season. This amount depends on several socioeconomic factors and preferences related to harvesters’ experiences.

Observational trend analysis is fundamental for documenting changes in river flows and placing extreme events in their longer-term historical context. Observations from near-natural catchments, i.e., with little or no alteration by humans, are of great importance in detecting and attributing streamflow trends. The purpose of this study is to analyze the annual and seasonal trends of stream discharge (mean, low and high flows) in a headwater catchment in NW Spain, i.e., in the wettest corner of the Iberian Peninsula. The results showed no significant decrease in the mean annual stream discharge. However, significantly lower summer and autumn mean stream discharge and an increase in low flow period were detected, in addition to lesser autumn high flow. The rainfall pattern followed an upward trend, but was not significant. This different pattern shown by rainfall and discharge indicates that is not sufficient to explain the observed trend in stream discharge. Air temperature, most notably by enhancing evapotranspiration, may explain the altered patterns of stream discharge.

Rainfall is the key factor to understand soil erosion processes, mechanisms, and rates. Most research was conducted to determine rainfall characteristics and their relationship with soil erosion (erosivity) but there is little information about how atmospheric patterns control soil losses, and this is important to enable sustainable environmental planning and risk prevention. We investigated the temporal and spatial variability of the relationships of rainfall, runoff, and sediment yield with atmospheric patterns (weather types, WTs) in the western Mediterranean basin. For this purpose, we analyzed a large database of rainfall events collected between 1985 and 2015 in 46 experimental plots and catchments with the aim to: (i) evaluate seasonal differences in the contribution of rainfall, runoff, and sediment yield produced by the WTs; and (ii) to analyze the seasonal efficiency of the different WTs (relation frequency and magnitude) related to rainfall, runoff, and sediment yield. The results indicate two different temporal patterns: the first weather type exhibits (during the cold period: autumn and winter) westerly flows that produce the highest rainfall, runoff, and sediment yield values throughout the territory; the second weather type exhibits easterly flows that predominate during the warm period (spring and summer) and it is located on the Mediterranean coast of the Iberian Peninsula. However, the cyclonic situations present high frequency throughout the whole year with a large influence extended around the western Mediterranean basin. Contrary, the anticyclonic situations, despite of its high frequency, do not contribute significantly to the total rainfall, runoff, and sediment (showing the lowest efficiency) because of atmospheric stability that currently characterize this atmospheric pattern. Our approach helps to better understand the relationship of WTs on the seasonal and spatial variability of rainfall, runoff and sediment yield with a regional scale based on the large dataset and number of soil erosion experimental stations.

Ammonia losses from manure pose serious problems for ecosystems and human and animal health. Gas-permeable membranes (GPMs) constitute a promising approach to address the challenge of reducing farm ammonia emissions and to attain the EU’s Clean Air Package goals. In this study, the effect of NH3-N concentration, membrane surface area, acid flux, and type of capture solution on ammonia recovery was investigated for a suspended GPM system through three experiments, in which ammonia was released from a synthetic solution (NH4Cl + NaHCO3 + allylthiourea). The effect of two surface areas (81.7 and 163.4 cm2) was first evaluated using three different synthetic N emitting concentrations (3000, 6000, and 12,000 mg NH3-N∙L−1) and keeping the flow of acidic solution (1N H2SO4) constant (0.8 L·h−1). A direct relationship was found between the amount of NH3 captured and the NH3-N concentration in the N-emitting solution, and between the amount of NH3 captured and the membrane surface area at the two lowest concentrations. Nonetheless, the use of a larger membrane surface barely improved ammonia capture at the highest concentration, pointing to the existence of other limiting factors. Hence, ammonia capture was then studied using different acid flow rates (0.8, 1.3, 1.6, and 2.1 L∙h−1) at a fixed N emitting concentration of 6000 mg NH3-N∙L−1 and a surface area of 122.5 cm2. A higher acid flow rate (0.8–2.1 L∙h−1) resulted in a substantial increase in ammonia absorption, from 165 to 262 mg of NH3∙d−1 over a 14-day period. Taking the parameters that led to the best results in experiments 1 and 2, different types of ammonia capture solutions (H2SO4, water and carbonated water) were finally compared under refrigeration conditions (at 2 °C). A high NH3 recovery (81% in 7 days), comparable to that obtained with the H2SO4 solution (88%), was attained when chilled water was used as the capture solution. The presented results point to the need to carefully optimize the emitter concentration, flow rate, and type of capture solution to maximize the effectiveness of suspended GPM systems, and suggest that chilled water may be used as an alternative to conventional acidic solutions, with associated savings.

The identification of the factors controlling the understory species distribution and abundance is essential to understand the ecology and dynamics of natural forests and their management response. We assess the relationships between environmental gradients and shrub functional groups distribution patterns and niche characteristics in a transitional area between the Eurosiberian and Mediterranean biogeographic regions in Northern Spain. Here, 772 plots from the 3rd Spanish National Forest Inventory were used. Shrub functional groups respond to the same complex environmental gradients as trees, i.e., the north-south climatic gradient and a slope gradient. Unimodal response curves of shrub functional groups and families dominate along both gradients, providing evidence of successful functional turnover. Similar to tree species, the niche location of functionally related shrubs is close. Functional groups occupying environments with sharp contrast or transitional environments have the broadest niches, whereas those specialized functional groups occupying localized habitats showed the narrowest niches. The knowledge of shrub species distributions and niche characteristics along complex environmental gradients will improve our ability to discuss potential conservation management goals or threats due to land-use changes and future climate change.

Research Highlights: The regeneration of Quercus species is usually very difficult in many
oak woodlands transformed by livestock farming. Some studies have reported that shrubs can
facilitate regeneration. However, the strength of interaction may vary depending on, among other
factors, the shrub species and the stress tolerance of the oak species. Moreover, further studies are
necessary to clarify the relative importance of the two facilitation mechanisms in the same community.
Background and Objectives: Cytisus multiflorus (L’Her.) Sweet is a predominant shrub species in
the Mediterranean grazed open-oak-woodlands found in the central west of the Iberian Peninsula
(bioclimatic limit) and is present with Quercus pyrenaicaWilld and Quercus ilex subsp. ballota Samp
trees. Thus, we assessed the effect of these native shrubs and acorn size, and the effect of excluding
large herbivores, on the seedling emergence of two contrasting co-occurring Quercus species under
a bioclimatic limit. Materials and Methods: A manipulative field experiment was carried out
considering four treatments as a combination of shrubs (shrub/no-shrub) and fence (fenced/open)
factors. A total of twenty plots, five replicates for each treatment were available. In each plot,
20 acorns were sown: 10 acorns (5 small and 5 large) for each Quercus species. Acorn emergence was
recorded during the first four years following the sowing. Results: Seedling emergence took place
mostly in the spring of the first year after sowing. The presence of shrub was the main significant
factor and incremented the emergence of both Q. ilex and Q. pyrenaica. The effect of the fence
depended on the Quercus species considered, improving only the emergence of Q. pyrenaica. A
negative effect with the small acorns was detected but only for Q. pyrenaica. In all treatments, Q. ilex
emerged more than Q. pyrenaica. Conclusions: C. multiflorus had a clear facilitative effect on the
seedling emergence of Q. ilex and Q. pyrenaica, which was much greater than the physical effect that
acorn size and excluding large herbivores had. As such, this native shrub may have a key role in
oak regeneration in Mediterranean grazed areas. Furthermore, in these areas of contact between
marcescent and sclerophyllous Quercus species, Q. ilex currently emerges more than Q. pyrenaica. This
could be indicative of a shift towards more xeric climatic conditions, which could lead to a change in
the dominant tree species in the future. However, this change could be modulated by the effects of
native shrub and large herbivores.

Tuber melanosporum (Ascomycota, Pezizales) is an ectomycorrhizal fungus that produces
highly appreciated hypogeous fruiting bodies called black truffles. The aim of this paper was
to research the composition of ectomycorrhiza-associated fungal and bacterial communities in T.
melanosporum oak plantations. Results of this paper showed the competitive effect of T. melanosporum
on other fungal species, especially other mycorrhizal and pathogenic species. T. melanosporum
was shown to be associated mainly with bacteria, some of them important for their properties as
mycorrhizal helper bacteria. A dendrogram analysis of co-occurrence showed that T. melanosporum
tended to co-occur with the following bacteria species: Singulisphaera limicola, Nannocistis excedens
and Sporosarcina globispora. In addition, it was linked to fungal species such as Mortierella elongata,
M. minutissima, Cryptococcus uzbekistanensis, C. chernovii and C. aerius. This study provides an
exhaustive analysis of the diversity, structure and composition of fungal and bacterial communities
associated with T. melanosporum to enhance understanding of the biology, composition and role of
these communities in truffle plantations.

Forests cover 31% of the global land area and are home to most of Earth’s terrestrial biodiversity. Forests supply a wide set of ecosystem services, provide livelihoods, mitigate climate change, and are essential for sustainable food production, contributing to the health of the planet. However, deforestation and forest degradation continue to take place at alarming rates in some parts of the world, whereas in others the trend has been reversed with forests expanding over abandoned agricultural areas.

Past studies have revealed the benefits of rodent participation in the colonization process of oak species. Certain rodent species (Apodemus sylvaticus and Mus spretus) partially consume acorns, beginning at the basal part and preserving the embryo. Perea et al. (2011) and Yang and Yi (2012) found that during periods of abundance, the remains left after partial consumption continue to be present on the surface and are not transported to caches, given that they are perceived as leftovers.
These remains, produced after several visits by the cache owner or by thieving conspecifics, also appear in the caches. If they are perceived as offal, they will not be attacked and may remain in these stores for longer periods, serving as resources for the cache builder.
Our objective is to determine whether these remnants are perceived as offal by the rodent generating them or if the remains left by other rodents are considered offal. This is relevant in cases of theft, a common behavior of this species, if the thieving animals reject the remains.
The results suggest that foreign remains and the rodents’ own remains are not rejected, but rather, they are consumed in preference to intact acorns. The intact acorns remain in the cache for longer periods and have a greater opportunity to germinate and emerge. Rodents prefer to consume foreign remains first. This may be due to the fact that, in case of shortage, it is considered advantageous to finish the reserves of a potential competitor before depleting one’s own reserves.

Among the main objectives of Natura 2000 Network sites management plans is monitoring their conservation status under a reasonable cost and with high temporal frequency. The aim of this study is to assess the ability of single-photon light detection and ranging (LiDAR) technology (14 points per m2) and Sentinel-2 data to classify the conservation status of oak forests in four special areas of conservation in Navarra Province (Spain) that comprise three habitats. To capture the variability of conservation status within the three habitats, we first performed a random stratified sampling based on conservation status measured in the field, canopy cover, and terrain slope and height. Thereafter, we compared two metric selection approaches, namely Kruskal–Wallis and Dunn tests, and two machine learning classification methods, random forest (RF) and support vector machine (SVM), to classify the conservation statuses using LiDAR and Sentinel-2 data. The best-fit classification model, which included only LiDAR metrics, was obtained using the random forest method, with an overall classification accuracy after validation of 83.01%, 75.51%, and 88.25% for Quercus robur (9160), Quercus pyrenaica (9230), and Quercus faginea (9240) habitats, respectively. The models include three to six LiDAR metrics, with the structural diversity indices (LiDAR height evenness index, LHEI, and LiDAR height diversity index, LHDI) and canopy cover (FCC) being the most relevant ones. The inclusion of the NDVI index from the Sentinel-2 image did not improve the classification accuracy significantly. This approach demonstrates its value for classifying and subsequently mapping conservation statuses in oak groves and other Natura 2000 Network habitat sites at a regional scale, which could serve for more effective monitoring and management of high biodiversity habitats.

Membrane technologies and chemical precipitation are among the best valued options for their economic and practical feasibility. In this study, the combination of gas-permeable membrane (GPM) technology for the recovery of nitrogen (N) and the chemical precipitation for phosphorous (P) recovery from anaerobically digested swine manure is evaluated. This work studies the effect of the membrane area and the addition of alkali on N and P recovery efficiencies. Specifically, two different membrane area ratios (180 and 100 g of N per m2 of membrane) with and without the addition of alkali were studied. High nutrient recovery efficiencies, of 77% for N and 80% for P, were obtained after 10 days of experiment with a ratio of 180 g N per m2 of GPM and the addition of NaOH (1.5 N), along with the precipitant agent (MgCl2) for P precipitation. Hence, a combined configuration was proposed to perform an effective simultaneous recovery of N and P with the minimum amount of membrane needed in a short time.

This study provides novel information about gregariousness and intraspecific aggression in Iberian bullfinches
(Pyrrhula pyrrhula iberiae) in northwestern Spain. Small monospecific parties never exceeding 10 individuals
were seen throughout the year, larger in winter on average. Males considerably outnumbered females within
the groups. Adult flocks were frequent only in winter. In spring, many of the adult groups were mixed-sex
assemblages composed of pairs plus supernumerary males. Sightings of juvenile groups, up to seven
individuals, were common in summer–autumn. The vigilance role in mixed-sex assemblages, including pairs,
appeared to be the responsibility of males based on sex-specific vigilance rates. The highest frequency of
aggressive encounters, mainly male against male, occurred during the breeding season, associated with mate
defence. Females attacked males, not the contrary, which supports reversed sexual dominance in bullfinches.
Gregariousness probably acted as an anti-predatory and foraging strategy.

The breeding ecology of the Iberian subspecies of the Eurasian
bullfinch, Pyrrhula pyrrhula iberiae, is addressed for the first time.
The studied population occupied a hedgerow habitat in northwestern
Spain. Individuals directly watched in the study area and
details of these sightings were recorded over a six-year period,
and a total of 56 nests were monitored. The earliest date of nest
building was within 11–30 April for all years. Fledglings were
recorded leaving the nest during all the ten-day periods from the
end of May to mid-August. Nest attendance, from the early building
stage to when nestlings were ready to leave the nest, lasted
approximately 36 days. The overall mean clutch size was 4.56
eggs. Clutch size decreased significantly at the end of the breeding
season. For all egg traits, the minimum values for standard deviation
were obtained in the intra-clutch analysis, and egg length was
more variable than width. Nesting success increased progressively
from April–May to June–July and August. The main proximate
cause of nest failure was egg desertion/predation, followed by
nest desertion during nest building and nestling desertion/predation.
Mammals were the main agents in nests where the probable
predator could be identified. Approximately half of the eggs
became fledglings leaving the nest, no significant seasonal differences
being observed for this parameter. In August, the ratio of
juveniles to adults was 2.5–4.1, juveniles representing approximately
70–80% of the individuals seen and identified that month.
The absence of significant interannual variation in important reproductive
parameters could have been due to lack of interannual
variation in the availability of food resources. Compared to other
subspecies, mean clutch size of Iberian bullfinches is the smallest
recorded in the western Palearctic, and they showed an earlier start
to the breeding season and shorter mean egg length than North
European and Russian populations.

Nest-habitat selection and nest design in a Eurasian bullfinch population in the Iberian Peninsula are thoroughly addressed in this study for the first time. Hedgerows and meadows were found around all of the nests and most of them were supported by hedgerows, so bullfinches consistently used the general woody vegetation available as reproduction habitat and site. Also, poplar plantations appeared preferentially in the immediate surroundings of the nests. Partly reflecting these results, bullfinches chose zones with greater shrub and tree cover than that available. Bullfinches placed their nests on a wide variety of plant species, but showed predilection for thorny species. Overall mean height of nests above the ground was 1.43 m and large-sized shrubs/trees were preferred. The most predominant bullfinch nest orientations were S, E and centered, which arguably provided thermal benefits and protected from severe weather. In general, there were no significant temporal variations in nest-site selection. With the exception of thorny support and favourable orientation, acting jointly, there was no significant association between nest-site characteristics and nesting success, presumably because many nests were already located in the most advantageous places at each time, and because despite this, predation pressure was high. Nest external dimensions were relatively variable, whereas internal width was the least variable nest dimension. No significant monthly or interannual variations in nest weight were observed. Larger nests did not hold larger clutches. Successful nests were larger than unsuccessful ones. The bullfinch nests were of simple construction, with two clearly different regions, the outer nest and the internal cup, with no significant temporal variations in the weight of either. The outer, structural nest consisted mainly of twigs, whereas roots and herbaceous shoots were the highest fractions lining the cup. Hair was the only animal-derived material used by bullfinches.

Background: For all vertebrates in general, a concerted effort to move beyond single season research is vital to
improve our understanding of species ecology. Knowledge of habitat use and selection by Eurasian Bullfinches
(Pyrrhula pyrrhula) is limited with regard to the non-breeding season. To date, research on the habitat of the Iberian
subspecies iberiae consists of very general descriptions. In relation to space use, only broad features are available for
the entire distribution range of Eurasian Bullfinches, including Iberia.
Methods: In this study, seasonal preferences regarding habitat and space in a population of Eurasian Bullfinches are
examined for the first time in the Iberian Peninsula, through direct observation during a six-year period. The essential
habitat components, substrate selection and perch height were assessed.
Results: Hedgerows were the key essential habitat component for bullfinches during all seasons. Nevertheless, small
poplar plantations became increasingly important from winter to summer-autumn. Bullfinches perched mostly in
shrubs/trees throughout the year, but there were significant seasonal changes in substrate use, ground and herbs
being of considerable importance during spring-summer. Throughout the year, over half of the records corresponded
to feeding, reaching almost 90% in winter. Generally, bullfinches perched noticeably lower while feeding. Male
bullfinches perched markedly higher than females, notably singing males in spring-summer. Juveniles perched at a
height not much lower than that of males. In all seasons, males tended to feed at greater heights than females. Bullfinches
of different ages and sexes were seen bathing in all seasons except winter.
Conclusions: Hedgerow habitat in general appeared to be valuable for bullfinches throughout the year. In summer
and autumn, they selected sites with an abundance of food and shade, as well as shelter, a much-needed
requirement for fledglings and moulting individuals. There was usually a close link between the most used and most
consumed plant species in each season. Males appeared to assume a more important role in vigilance, and often they
accompanied dependent young in June and July. Bullfinch conservation strategies should consider seasonal demand
for habitat and space.

The first comprehensive approach to the feeding ecology of Iberian bullfinches Pyrrhula pyrrhula iberiae is presented here.
The target population inhabited hedgerows in northwestern Spain. Throughout a 6-year main period, the bullfinches were
directly observed while searching for and consuming food. Interannual variation in diet was irrelevant, so data from all
years were pooled. Availability of plant species and their selection as food resource was assessed. The general categories of
food consumed varied significantly between seasons, with a high contribution of fleshy fruits in autumn–winter, tree buds
in spring, and herb seeds in summer. The breeding season diet included a considerable proportion of invertebrates. Generally,
sex- and age-related variations in diet were not significant throughout the seasons. Bullfinches preferred specific plant
species as a food resource in each season and ignored others. The selected fleshy fruit seeds were small in size, in particular
thickness, which probably made handling easier. The most consumed buds were numerous per cm of twig and were flower
buds, which presumably provided, comparatively, high energy gain per unit time. Generally, favourite herb seeds were contained
in small achenes, easy to handle and dehusk. Invertebrate prey identified was small insects and spiders. Bullfinches
obtained most of their food while perching, regardless of sex or age, but some important fruits, and the arthropods, were
frequently obtained in flight. The high diversity of woody plants and food sources found in hedgerows surely protected fruit
trees from the detrimental effect of bullfinches and provided this passerine species with a wide range of habitat resources.

For the first time, the diet of young Iberian Bullfinches (Pyrrhula pyrrhula iberiae)
is studied, specifically in a hedgerow habitat in northwestern Spain, through stomach
(younger nestlings up to 8 days of age, which died without researcher intervention) and
faecal sac (older nestlings) analysis, and secondarily direct observation (nestlings and
dependent juveniles). Also, for the first time, grit use by bullfinch nestlings is described
in some detail. Bullfinches fed their young with a mixture of seeds and invertebrates,
with greater quantitative importance of the former. The identity of the seeds varied
considerably between spring and summer, and animal fraction gradually decreased from
May to July for older nestlings, in both cases presumably because of the seasonal changes
in food availability. Caterpillars and spiders were the most important arthropod prey in
the diet. Apparently, the young were not fed non-arthropod invertebrates. The relative
importance of invertebrates, which are very rich in proteins, was greater for younger
nestlings than for older ones. Difficult to digest hard-bodied prey, such as beetles, were
not present in the stomachs of the youngest nestlings. The frequency of occurrence and
amount of grit in stomachs increased with nestling age, along with the need to grind
food. There were no remarkable differences in number of units, size, or number of colour
types of gastroliths between months. The high floristic diversity in the study area, which
has great overall conservation value, provides a wide range of resources for bullfinches,
including plenty of food for their young.

Little is known about Eurasian Sparrowhawk Accipiter nisus feeding habits outside the breeding season in its wide geographical range. The present study concerns the autumn-winter and spring-summer diet of this raptor species in Northwest Spain in a hedgerow habitat. A total of 23 avian prey species were recorded, only six of which occurred in both periods of the year. However, Eurasian Sparrowhawks fed mainly on medium-sized birds that often forage on the ground at some distance from shrubs and trees, mostly the Song Thrush Turdus philomelos and the Common Blackbird Turdus merula, both species together accounting for approximately half of the prey in any season of the year. The contribution of larger birds, i.e., pigeons, was considerable in terms of ingested biomass. In spring-summer, the mean body weight of avian prey was over 15 g less than in autumn-winter.

We screened 526 wild small mammals for zoonotic viruses in northwest Spain and found hantavirus in common voles (Microtus arvalis) (1.5%) and high prevalence (48%) of orthopoxvirus among western Mediterranean mice (Mus spretus). We also detected arenavirus among small mammals. These findings suggest novel risks for viral transmission in the region.

Cistus ladanifer scrublands, traditionally considered as unproductive, have nonetheless been observed to produce large quantities of king bolete (Boletus edulis) fruitbodies. These pyrophytic scrublands are prone to wildfires, which severely affect fungi, hence the need for fire prevention in producing C. ladanifer scrublands. In addition, B. edulis productions have severely decreased in the last years. A deeper understanding of the B. edulis life cycle and of biotic and abiotic factors influencing sporocarp formation is needed to implement management practices that facilitate B. edulis production. For example, some bacteria likely are involved in sporocarp production, representing a key part in the triple symbiosis (plant–fungus–bacteria). In this study, we used soil DNA metabarcoding in C. ladanifer scrublands to (i) assess the effect of site history and fire prevention treatment on bacterial richness and community composition; (ii) test if there was any correlation between various taxonomic groups of bacteria and mycelial biomass and sporocarp production of B. edulis; and to (iii) identify indicator bacteria associated with the most productive B. edulis sites. Our results show that site history drives bacterial richness and community composition, while fire prevention treatments have a weaker, but still detectable effect, particularly in the senescent plots. Sporocarp production correlated positively with genera in Verrucomicrobia. Several genera, e.g. Azospirillum and Gemmatimonas, were identified as indicators of the most productive sites, suggesting a potential biological role in B. edulis fructification. This study provides a better understanding of the triple symbiosis (plant–fungus–bacteria) involved in C. ladanifer–B. edulis systems.

Eucalyptus tree species are widely used in Ethiopian plantations, but the impact of these plantations on the soil fungal communities is still unknown. We assessed the changes in diversity, species composition and ecological guilds of the soil fungal communities across tree ages of Eucalyptus grandis plantations by DNA metabarcoding of ITS2 amplicons. Changes in soil fungal species composition, diversity and ecological guilds were related to stand age but also to fertility changes. The relative abundance of saprotrophs and pathogens were negatively correlated with stand age, and positively with soil fertility. In contrast, the relative abundance and diversity of ectomycorrhizal species were higher in older, less fertile stands, including well-known cosmopolitan species but also species associated with Eucalyptus, such as Scleroderma albidum and Descomyces albellus. We show that soil fungal community changes are linked to progressive soil colonization by tree roots but are also related to soil fertility changes.

Ethiopian dry Afromontane forests are complex ecosystems that have important economic and ecological roles. However, recurrent fire has been a source of disturbance for these forests. We assessed the effect of fire on soil fungal communities in a remnant dry Afromontane forest in Wondo Genet, southern Ethiopia, by analysing soil samples collected from unburned stands and from stands one and ten years after fire using DNA metabarcoding of the ITS2 rDNA. The analysis indicated that the soil fungal community was most diverse soon after a fire disturbance and declined over time. Fungal community composition also differed among stands. Our results also indicated that differences in fungal diversity were stand dependent rather than due to the chronology of the fire history in this forest system. We found higher numbers of mycorrhizal species in burned stands, suggesting that these fungal symbionts could compensate for the effects of nutrient stress caused by fire in these areas. Fungal community composition was also significantly correlated with organic matter content, potassium and magnesium in soil. This work could be considered as a case study since the plots were established in a single stand for each treatment in the dry Afromontane forests of Ethiopia. Thus, we recommend further studies and conclusions regarding other stands need to be taken with caution.

Research Highlights: Carpathian forests hold high ecological and economic value while generating conservation concerns, with some of these forests being among the few remaining temperate virgin forests in Europe. Carpathian forests partially lost their original integrity due to their management. Climate change has also gradually contributed to forest changes due to its modification of the environmental conditions. Background and Objectives: Understanding trees’ responses to past climates and forms of management is critical in foreseeing the responses of forests to future conditions. This study aims (1) to determine the sensitivity of Carpathian forests to past climates using dendrochronological records and (2) to describe the effects that climate change and management will have on the attributes of Carpathian forests, with a particular focus on the different response of pure and mixed forests. Materials and Methods: To this end, we first analysed the past climate-induced growth change in a dendrochronological reference series generated for virgin forests in the Romanian Curvature Carpathians and then used the obtained information to calibrate spatially explicit forest Landis-II models for the same region. The model was used to project forest change under four climate change scenarios, from mild to extreme. Results: The dendrochronological analysis revealed a climate-driven increase in forest growth over time. Landis-II model simulations also indicate that the amount of aboveground forest biomass will tend to increase with climate change. Conclusions: There are differences in the response of pure and mixed forests. Therefore, suitable forest management is required when forests change with the climate.

Key message: Acacia melanoxylon produces abundant seeds leading to large seed banks in the soil. These seeds display a large viability and their germination is stimulated by heat. To control the populations, it is necessary to remove adults and young individuals, and to prevent seedling establishment after fire occupying the space with rapid growth and high competitive native species.
Context: Acacia melanoxylon displays a widespread distribution in South West Europe, and an improved knowledge of its reproductive characteristics is required in order to control its expansion.
Aims: This experiment was designed to provide useful indicators for an efficient management of A. melanoxylon populations based on its biological cycle in relation to fire.
Methods: We explored the reproductive biology of A. melanoxylon, from seed dissemination—–quantifying seed rain over a year, their germination with and without fire—the seedling and sapling banks and the structure of the adult population. We analysed the effects of fire, seed maturation and scarification on the viability of seeds and the stimulation of seed germination in the aerial seed bank and in the different strata of the soil seed bank.
Results: Our results indicate that A. melanoxylon produced millions of seeds per ha and per year, half of which germinated and the other half went to the soil seed bank, maintaining the viability many years. The germination was the most critical step in the population dynamics of this species, and fire stimulates germination up to 90%.
Conclusion: A. melanoxylon adults and seedlings removal, followed by colonization of rapid growth and high competitive native species that cover the ground very quickly would be a good control action.
The study formed part of the project GESFIRE (AGL2013-48189-C2-R) financed by the Minister of Economy and Competitiveness, Government of Spain, and by FEDER.

Paraserianthes lophantha (Willd.) I. C. Nielsen is a plant species native to SW Australia that has recently invaded temperate ecosystems in Europe and other areas in the world. Since it has been found in burnt areas and its expansion could be promoted by forest fires, the germination response of seeds to fire factors (heat, smoke, ash and charcoal) was analyzed. Furthermore, stochastic post-fire invasion models were developed to check the impact of one-off and repeated forest fires. The spreading pattern after fire was modeled to provide accurate forecasts for future fires. The model was parameterized using data recorded after the 2013 forest fire in the Natura 2000 site Monte Pindo. Germination response is mainly modified by heat, which breaks seed dormancy at moderate temperature and kills seeds at high temperatures. Smoke, ash and charcoal did not have relevant influence on seed germination except large amounts of ash, which prevented seed germination. Neither charcoal origin (from native or from exotic species) had a significant effect on P. lophantha germination. The invasion model demonstrated the significant role of forest fires promoting P. lophantha spreading. Recurrent fires promote the spreading of invasive species, threatening natural plant communities. However, the expansion of the species was not exclusively linked to forest fires: anthropic systems, edges of agricultural areas and old fields were particularly affected by P. lophantha expansion. Some control methods based on the reproductive behavior and spreading pattern of P. lophantha were proposed in order to prevent new invasions and manage invaded areas.

Tree height measurements are laborious and require more time and effort compared to tree diameter measurements. That being the case, height-diameter (H-D) models are usually used to predict individual tree heights, which are necessary for estimating the tree volume and the site index, as well as for projecting the stand development over time. Using a permanent sampling network (400x400m) from Retezat National Park in Romania, twenty-one (H-D) functions were evaluated for their fit performance, sensitivity to outliers and prediction ability for Norway spruce in mixed uneven aged stands. A set of twenty-three stand variables, both spatial and non-spatial, were used to describe the stand structure, species inter-mingling and competition, in order to be used as stand predictors in a generalized H-D model. Nonlinear mixed effects model was used in modelling the H-D relationship of Norway spruce. We developed the first generalized height-diameter model in Romania using three stand predictors as measures of the stand vertical structure, density and competition. Random and fixed effects calibration techniques were compared, testing various sampling designs in order to improve the height prediction accuracy of the model on a new dataset. Measuring six trees around the median and the thickest tree gave the best result in calibrating both fixed and random effects. On average, the best calibration design increased the accuracy of the prediction by 50 cm compared to the fixed effects prediction. The use of the estimated coefficients and the calibration design will significantly decrease the amount of work done by forest management planners, while ensuring high accuracy and reducing costs.
The dataset used in this study was provided by a Core GENERESERV project supported by the Romanian Ministry of Research and Innovation within the National “Nucleu” Program – project code PN 09460117 aimed at long-term monitoring of the state of forest ecosystems.

Forest ecosystems cover 31% of the world [1], providing a wide range of essential ecosystem services in terms of climate and hydrological regulation, biodiversity protection, timber and food production, or recreation, as well as others. However, forests are subject to changes due to natural hazards and anthropogenic pressures, which are predicted to increase under current climate change and socio-economic demands. Sustainable forest management is paramount to reaching two sustainable development goals (SDGs) set out to be achieved in the 2030 Agenda: take actions for the environment by combatting climate change (Goal 13), and protect, restore, and promote the sustainable use of terrestrial ecosystems (Goal 15). Current and future forestry practices rely on quantitative and qualitative information traditionally collected using field-based surveys, and increasingly complemented or surrogated with remote sensing datasets.
