Evolutionary dynamics of temporal niche among tetrapods

Jacinta Guirguis, Jhoann Canto, Catherine Sheard, Daniel Pincheira‐Donoso

This study analyzes the evolutionary dynamics of temporal niche use across tetrapods, finding increased diurnality and faster temporal niche evolution in amphibians post-K-Pg extinction.

Generalist temporal niche buffers against extinction risk among non-avian tetrapods

Jacinta Guirguis, Catherine Sheard, Daniel Pincheira‐Donoso

The paper examines how temporal niche (diurnal, nocturnal, cathemeral) affects extinction risk across non-avian tetrapods, finding cathemerality reduces population declines while diurnality increases risk in amphibians.
