Epixylic diversity in an old-growth boreal forest is influenced by dynamic substrate attributes
Quantifying the factors influencing wood-inhabiting species in boreal forests is crucial for better understanding of their ecology and conservation needs. We estimated the influence of substrate attributes on epixylic diversity on logs of Picea abies, Betula pubescens, B. pendula, Populus tremula an...

Quantifying the factors influencing wood-inhabiting species in boreal forests is crucial for better understanding of their ecology and conservation needs. We estimated the influence of substrate attributes on epixylic diversity on logs of Picea abies, Betula pubescens, B. pendula, Populus tremula and Pinus sylvestris in a mixed European old-growth boreal forest with high substrate availability and continuity. The number of species of different taxonomic and substrate groups in respect of log attributes was estimated with generalized linear models. The composition of epixylic communities was analysed using non-metric multidimensional scaling with subsequent environmental fitting. Additionally, we calculated species interaction networks of log (tree) species and epixylic plants and lichens.
