Bat community assembly in the ecotone of two neotropical biodiversity hotspots is determined by environmental filtering rather than historical factors. [PDF]

open access: yesJ Anim Ecol
We demonstrate that environmental filtering is the primary mechanism shaping bat communities across the Cerrado–Atlantic Forest ecotone. By integrating phylogenetic diversity, environmental gradients, and coevolutionary assembly models, our study provides new insights into the processes maintaining biodiversity in a globally important transition zone ...

Managers employ several mitigation measures to reduce vessel strike risk, including establishing or modifying vessel routing measures, such as shipping lanes. However, most studies utilized to inform the configuration of shipping lanes only consider a limited number of potential lanes, and in ...
