Data for taxon-dependent effects of dispersal limitation versus environmental filters on bryophyte assemblages―Multiple perspective studies in land-bridge islands

Aim: To explore the taxon-dependent contribution of dispersal limitation vs. environmental filters to bryophyte assemblages. Location: The Thousand Island Lake, China Taxon: Bryophytes Methods: We compared the observed beta diversity with the expected values based on six null models (EE, EF, FE, FF, PE, PF) and detected the partial correlation of beta diversity with geographical distances. We quantified the contributions of spatial vs. environmental variables, and island isolation per se to species composition (SC) by using variance partitioning. We modeled the species-area relationships (SARs) for bryophytes and other eight biotas. To explore the taxon-dependent effects of spatial vs. environmental filters on bryophytes, sixteen taxa including five categories (total bryophytes, total mosses, liverworts, acrocarpous and pleurocarpous mosses) and eleven species-richest families were included in the analyses. Results: The observed beta diversity values were significantly different from t..., ,
