Comparative endocranial anatomy in the crocodylians Leidyosuchus canadensis and Stangerochampsa mccabei from the upper Cretaceous of Alberta, Canada

open access: yesJournal of Anatomy, EarlyView.
Leidyosuchus canadensis and Stangerochampsa mccabei share endocranial features such as posterior projection of a neurovascular canal in the maxilla and a paratympanic sinus system most similar to those of small‐bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.

Illegal trade of crocodylians in Colombia: Spatiotemporal dynamics and implications on conservation efforts

open access: yesConservation Science and Practice, Volume 7, Issue 7, July 2025.
Crocodylian conservation effectiveness has been limited by illegal trade as well as changes in control and trade policies. We assessed spatiotemporal dynamics of illegal crocodylian trade in Colombia from 2010 to 2022 based on data collected by regional and district environmental authorities and discussed its implications on conservation efforts ...

Positive Selection of TLR2 and MyD88 Genes Provides Insights Into the Molecular Basis of Immunological Adaptation in Amphibians

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
We found that recurrent positive selection has acted on TLR2 and MyD88 in amphibians and positively selected sites were mainly located at or close to function domains. Our results suggest that amphibians have adapted to different pathogenic microorganisms during their transition from the aquatic to terrestrial environment and diversification into ...
