2020-05-06T12:10:24Z urn:hdl:10324/40818 Sydowia polyspora dominates fungal communities carried by two Tomicus species in pine plantations threatened by Fusarium circinatum Muñoz Adalia, Emigdio Jordan Sanz Ros, Antonio Vicente Flores Pacheco, Juan Asdrúbal Hantula, Jarkko Díez Casero, Julio Javier Vainio, Eeva J. Fernández Fernández, María Mercedes Producción Científica 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. 2020-05-06T12:10:24Z 2020-05-06T12:10:24Z 2017 info:eu-repo/semantics/article Forests, 2017, vol. 8, n. 4. 16 p. 1999-4907 http://uvadoc.uva.es/handle/10324/40818 10.3390/f8040127 eng https://www.mdpi.com/1999-4907/8/4/127 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ © 2017 MDPI Attribution-NonCommercial-NoDerivatives 4.0 Internacional MDPI
