Evolution of research on global amphibian declines
Conservation Biology, Volume 40, Issue 1, February 2026.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 ...

Occupancy and Niche Dynamics of Iberian Freshwater Fish Across 25 Years
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 10, October 2026.ABSTRACT Global change is reshaping biological communities, leading to shifts in community composition, species distributions and species realized niches. These processes are especially relevant in freshwater ecosystems, where vertebrate declines are particularly severe and dispersal is naturally constrained by drainage basins.
