Divergent Paths, Convergent Heads: Morphological Adaptation of Head Shape to Habitat Use and Diet in Snakes

open access: yesJournal of Morphology, Volume 286, Issue 11, November 2025.
Snake head shape is weakly constrained by phylogeny but strongly influenced by ecology. Significant convergence was detected in fossorial and aquatic snakes, while diet mainly drove morphological variation without convergence. ABSTRACT Morphological convergence—where distantly related species evolve similar traits in response to shared ecological ...

Surface Topography and Ultrastructure of the Spectacular Cells in the Eyes of Land and Sea Snakes (Squamata, Reptilia): Functional Adaptations of Micro‐Ornamentation

open access: yesJournal of Morphology, Volume 286, Issue 9, September 2025.
ABSTRACT Although the surface micro‐ornamentation of the scales within the skin of snakes has been the subject of many previous studies, there has been little work done on the spectacle, a protective (keratinised) goggle separated from the underlying cornea by a sub‐spectacular space. The surface ultrastructure of the “Oberhäutchen” of the spectacle is

Trophic Ecology of the Cuban Boa, Chilabothrus angulifer (Boidae)

open access: yesReptiles & Amphibians, 2020
The Cuban Boa (Chilabothrus angulifer) is a top terrestrial predator in Cuba. References to prey species consumed by this boa date to when the first Europeans arrived in the region more than 500 years ago. However, long-term studies on its trophic ecology do not exist.

Effect of Soil Properties on Species Richness of Fossorial Squamate Reptiles

open access: yesJournal of Biogeography, Volume 52, Issue 6, June 2025.
ABSTRACT Aim Species richness varies greatly over geographic gradients. Climate and other above‐ground attributes are the most common variables used to explain animal richness patterns. However, soil properties may play an important role in shaping the richness of species living underground.

Biogeographic Implications of Biodiversity Shortfalls in a Mid‐Altitude Desert Ecotone of the Arabian Peninsula

open access: yesDiversity and Distributions, Volume 31, Issue 3, March 2025.
ABSTRACT Aim Macroscale biodiversity inferences are critical for spatial conservation planning, yet they are affected by the limitations of global datasets and the paucity of genetic data. In this study, we conducted a comprehensive sampling campaign and explored how biodiversity shortfalls impact spatial diversity metrics across a mid‐altitude desert ...
