Multispecies landscape functional connectivity enhances local bird species’ diversity in a highly fragmented landscape

Local species assemblages are likely the result of habitat and landscape filtering. However, there is still limited knowledge on how functional connectivity complements attributes in mediating local real-world fragmented landscapes. In this study, we set up a non-manipulative experimental design standard production forest to demonstrate determines spatial distribution bird community. We test single- multispecies spatially explicit, models framed within circuit theory, considering also patch describing size quality, weight their effects occurrence community assemblage. found that single-species contributed positively for each species. they rarely provided competing alternatives predicting parameters when compared models. Incorporating showed more consistent all parameters, than models, since overlap between species’ dispersal abilities shows poor agreement. Habitat though less important, were determinant explaining while possibly relating provision suitable nesting foraging conditions. Both filters concur govern assembly, influencing different processes: which can reach patch, quality settle patch. Our results suggest surrogating from single has potential source bias by assuming perceive its barriers similarly. Inference issue must be gathered as much possible.
