Generation length of the world's amphibians and reptiles

open access: yesEcography, Volume 2025, Issue 7, July 2025.
Variation in life histories influences demographic processes, from adaptive changes to population declines leading to extinction. Among life history traits, generation length offers a critical feature to forecast species' demographic trajectories such as population declines (widely used by the IUCN Red List) and adaptability to environmental change ...

Interplay of Genotypic and Thermal Effects on Sex Determination Shapes Climatic Distribution in Herpetofauna

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 7, July 2025.
ABSTRACT Aim Sex is a fundamental trait of many organisms, and sex‐determination systems are diverse across the tree of life. Environmental temperature can influence sexual development not only in temperature‐dependent sex‐determination systems, but also in species with genotypic sex determination (GSD). Temperature‐induced sex reversal, resulting from

The heart and aortic arches of rhinatrematid caecilians (Amphibia: Gymnophiona) [PDF]

open access: yesZoological Journal of the Linnean Society, 1996
Previous studies have shown there to be considerable inter-specific variation in the cardiovascular anatomy of five of the six families of caecilians. Observations on the previously unstudied Rhinatrematidae reveal this family to be characterized by a number of cardiovascular features that are unique within the Gymnophiona.
