Spatial Structure Explains Morphological Variation Better Than Climatic Gradients in the South American Rattlesnake (<i>Crotalus durissus</i>). [PDF]

Ecol Evol
We evaluated whether climatic gradients or spatial structure better explain body size variation in the South American rattlesnake (Crotalus durissus) across its wide geographic range. After explicitly accounting for spatial autocorrelation, climatic variables were not significant predictors of body size in either sex, whereas sex‐specific spatial ...

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.

Intraspecific Differences in the Venom of Crotalus durissus cumanensis from Colombia. [PDF]

Toxins (Basel), 2022
Biochemical and biological differences in the venom of Crotalus durissus cumanensis from three ecoregions of Colombia were evaluated. Rattlesnakes were collected from the geographic areas of Magdalena Medio (MM), Caribe (CA) and Orinoquía (OR). All three regionally distributed venoms contain proteases, PLA2s and the basic subunit of crotoxin.

Pharmacodynamics of propofol and alfaxalone in rattlesnakes (Crotalus durissus) [PDF]

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2021
To characterise the effect of two common induction agents, propofol and alfaxalone, on mean arterial blood pressure (MAP) and heart rate (HR), we equipped 19 adult South American rattlesnakes (Crotalus durissus) with an indwelling arterial catheter approximately 24 h prior to recording of baseline resting values. Then, seven snakes received alfaxalone (

Geographic variation of individual venom profile of Crotalus durissus snakes. [PDF]

J Venom Anim Toxins Incl Trop Dis, 2020
South American rattlesnakes are represented in Brazil by a single species, Crotalus durissus, which has public health importance due to the severity of its envenomation and to its wide geographical distribution. The species is subdivided into several subspecies, but the current classification is controversial. In Brazil, the venoms of C. d.
