On the Fila Olfactoria and the Cribriform Region of the Crocodylia

Journal of Morphology, Volume 286, Issue 2, February 2025.
The fila olfactoria of Alligator mississippiensis courses through a perforated pad of dense connective tissue to reach the olfactory bulb. The perforations are formed by perineural spaces, which produce continuity between the CSF and the olfactory submucosa.

Breeding bird response to adaptive multi‐paddock and continuous grazing practices in Southeastern United States

Ecosphere, Volume 15, Issue 12, December 2024.
Abstract Grassland bird populations are declining steeply, reflecting the degradation and loss of native grassland habitats. To assess how grazing management affects declining grassland bird populations, we compared breeding avifaunal communities in adaptive multi‐paddock (AMP) grazed and continuously grazed (CG) pastures in the Southeastern United ...

Turbinal bones are still one of the last frontiers of the tetrapod skull: hypotheses, challenges and perspectives

Biological Reviews, Volume 99, Issue 6, Page 2304-2337, December 2024.
ABSTRACT Turbinals are bony or cartilaginous structures that are present in the nasal cavity of most tetrapods. They are involved in key functions such as olfaction, heat, and moisture conservation, as well as protection of the respiratory tract. Despite recent studies that challenged long‐standing hypotheses about their physiological and genomic ...
