Habitat fragmentation (Sensu lato) represents a landscape-scale process involving both habitat loss and the breaking apart of (habitat per se). In ecological studies, understanding impacts se on biodiversity remains critical challenge. While previous research has explored effects various ecosystems, significant gaps remain in our its bryophyte assemblages. To explore assemblages subtropical forests, we investigated bryophytes environments 18 fragmented forest landscapes (including 166 islands) Thousand Island Lake, China. Landscape-level environmental variables included island number, mean area, area variability, shape irregularity, isolation degree. amount was represented by total within study landscape. We species richness (SR) coverage edge zones interior thirteen islands to forests bryophytes. Variance partitioning revealed that independently explained 38.92% variation SR 36.5% composition (SC). 6.2% 5.9% SC variation. Among associated with se, number irregularity were identified as most significant, explaining 16.2% 15.5% SR, respectively. variability 5.3% 2.1% variations A linear increase observed while nonlinear relationship detected variability. influenced similar extents, 6.6% SC. Consequently, had pronounced forests. Such likely due positive Our findings suggest that, secondary reserve for better contain numerous patches irregular shapes, large moderate area.
