Trade‐offs for butterfly alpha and beta diversity in human‐modified landscapes and tropical rainforests

Assessing conservation regionalization schemes: employing a beta diversity metric to test the environmental surrogacy approach
... The spatially contiguous environmental regionalizations (BCR, ecoregions and species-based) were shown to be more effective at delineating avian beta diversity, based on the GO and GA tests. Conversely, the ...
