Evolution of research on global amphibian declines. [PDF]

Conserv Biol
Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

Interplay of diet and sympatry in the morphological evolution of noctilionoid bats

Journal of Biogeography, Volume 50, Issue 12, Page 2084-2094, December 2023., 2023
Abstract Aim The remarkable ecomorphological diversity of the bat superfamily Noctilionoidea is the result of a diet‐mediated adaptive radiation. Stemming from a putatively insectivorous ancestor, noctilionoid bats diversified to adapt to the widest range of dietary ecologies among mammals.
