File S1 - Are Temperate Canopy Spiders Tree-Species Specific?

Supporting figures and tables. Figure S1. Map displaying distance between study trees in Poland. The Białowieża forest was the main research area and all forest plots were embedded in the forest matrix. We also collected spiders in the forests of Kampinoski, Borecka and Nurzec which were at least 50 km away from the Białowieża forest. Figure S2. Correspondence analysis displaying deciduous trees with a tree-species-specific pattern. Figure S3. Correspondence analyses displaying presence-absence data (a,c,e) and data without singeltons and tourists (b,d,f) for all data (a,b) and deciduous (c,d) and coniferous trees (e,f) separately. Table S1. Dufrene-Legendre indicator species analysis identifying characteristic species for deciduous and coniferous trees and for tree species. Figure S4. Guild composition differed between tree species as demonstrated by analysis of similarity (ANOSIM). Box-plots show dissimilarity of spider community composition between and within trees. After correcting for multiple testing according to Benjamini-Höchberg, significant differences in guild composition were found for the comparisons of P. sylvestris with A. glutinosa, Q. robur and P. abies (grey). Table S2. Abundance of all 140 spider species sorted according to their total abundance. Abbrev = Abbreviation of species names. A.g. = A. glutinosa, B.p. = B. pendula, C.b. = C. betulus, P.t. = P. tremula, Q.r. = Q. robur, P.a. = P. abies, P.s. = P. sylvestris. (PDF)
