An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia). [PDF]

Anat Rec (Hoboken)
Abstract Caecilians comprise a relatively small (~220 species) group (Gymnophiona) of snake‐like or worm‐like, mostly tropical amphibians. Most adult caecilians are fossorial, although some species may live in aquatic or semi‐aquatic environments, either as larvae or adults.

Identifying hotspots of faunal data deficiency to direct urgent research and monitoring

Conservation Biology, EarlyView.
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

Drivers of individual plant species contributions to β‐diversity are scale‐dependent

Oikos, Volume 2026, Issue 8, August 2026.
Species introductions and local extinctions of native species are driving biotic homogenisation in plant communities by reducing β‐diversity. Individual species vary in their contributions to β‐diversity (species contribution to β‐diversity; species‐β), yet our understanding of how species characteristics shape these contributions remains limited ...

Panama Canal expansion and shifts in fishing practices: A social‐ecological network approach

People and Nature, Volume 8, Issue 5, Page 1520-1532, May 2026.
Abstract Species introductions have spiked over the past two centuries due to globalization. These introductions impact ecosystems, but may also have long‐term implications for human communities. In one of the world's hubs for global shipping, the Panama Canal, a recent canal expansion has coincided with an increase in marine fishes entering the ...
