Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

The Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

The Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Human-Wildlife Conflict at a Suburban–Wildlands Interface: Effects of Short- and Long-Distance Translocations on Red Diamond Rattlesnake (Crotalus ruber) Activity and Survival

Diversity, 2022
The mitigation of human-rattlesnake conflicts often involves euthanizing or translocating the offending rattlesnake. Although translocation is generally considered more humane, especially by the general public, it may negatively impact the translocated ...

Comparative sex chromosome genomics in snakes: differentiation, evolutionary strata, and lack of global dosage compensation. [PDF]

PLoS Biology, 2013
Snakes exhibit genetic sex determination, with female heterogametic sex chromosomes (ZZ males, ZW females). Extensive cytogenetic work has suggested that the level of sex chromosome heteromorphism varies among species, with Boidae having entirely ...

Classroom boundaries and teacher agency: Challenges of implementing Ireland's new primary curriculum

The Curriculum Journal, EarlyView.
Abstract This article reports on a doctoral study examining teacher agency in one Irish primary school at a timely moment ahead of the implementation of the new Primary Curriculum Framework in September 2025. The framework embeds teacher agency as a central professional principle, yet findings from this study reveal a more cautious and bounded reality.
