Occurrence and evolution of cannibal behaviour in extant snakes. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Extant snakes (Serpentes) are a highly diverse group of squamate reptiles, which have independently evolved key morphological adaptations to consume a large variety of vertebrate and invertebrate prey. While these predator–prey interactions have been widely addressed by several studies, little is known regarding the occurrence of cannibal ...

A Case Report of Postpartum Hemorrhage Secondary to Snake Bite Envenomation: A Pathogenesis and Current Management Review. [PDF]

Case Rep Obstet Gynecol
Background Snakebite envenomation (SBE) is a tropical disease with significant global morbidity and mortality, particularly affecting low‐resource settings. During pregnancy, SBE poses unique challenges, increasing both maternal and fetal mortality. Limited access to antivenom and delayed treatment further worsen outcomes.

Biodiversity and Conservation Challenges in the Alédjo Wildlife Reserve (AWR) in Togo: Insights From Ethnozoological Surveys. [PDF]

Ecol Evol
The present study analyzes wildlife species use indices and a vulnerability in the Aledjo Wildlife Reserve (AWR) in Togo. The Importance Value‐in‐use Index (IVIUsp) indicates that the most valued species are the patas monkey (Erythrocebus patas), the forest cobra (Naja melanoleuca), and the green mamba (Dendroaspis viridis).

Inside the head of Crotalus durissus LINNAEUS, 1758 (Serpentes, Viperidae, Crotalinae): Macroscopic description of the brain with ontogenetic insights. [PDF]

Anat Rec (Hoboken)
Abstract Neuroanatomy studies in vertebrates have garnered significant attention in recent years, particularly driven by advancements in computerized tomography imaging techniques. Nonetheless, these advancements remain largely constrained to specific vertebrate groups, notably mammals, birds, and fish, leaving studies in reptiles at an incipient stage.
