摘要: Abstract Phylogenetically related species are assumed to be ecologically similar. Ecological similarity might lead competition and low distributional overlap. Therefore, if competitive interactions drive assemblages, we expect a decrease in overlap with increasing phylogenetic relatedness over-dispersion assemblages. We tested this hypothesis by evaluating the mean distance of bat assemblages within grid cells ≈36 km 2 across Bavaria, Germany (887 grids; 20,023 records). To calculate between species, used tree derived from sequences three mitochondrial genes (cytb, COI, ND1), two nuclear-protein-encoding (vWF, RAG2) encoding16S rRNA, 12S rRNA tRNA-Val. Overall, co-occurring were more similar than expected null models (phylogenetic clustering). This suggests that on considered scale, triggered environmental filters competition. Furthermore, decreased amount anthropogenic habitats grids. contrasts richness bats, which increased habitats.
