Potential Causes of Shedding Aggregations in Prairie Rattlesnakes. [PDF]
Ecol EvolThe mechanisms that underpin aggregation behavior in animals—and the cues that elicit it—inform our understanding of how animals resolve tradeoffs among selection pressures. We documented aggregation during ecdysis in a population of asynchronously shedding prairie rattlesnakes (Crotalus viridis) and tested predictions generated from the four ...

Tetrodotoxin-insensitive electrical field stimulation-induced contractions on Crotalus durissus terrificus corpus cavernosum. [PDF]
PLoS ONE, 2017 Reptiles are the first amniotes to develop an intromitent penis, however until now the mechanisms involved in the electrical field stimulation-induced contraction on corpora cavernosa isolated from Crotalus durissus terrificus were not investigated ...

A Review of Rattlesnake Venoms
Toxins, 2023 Venom components are invaluable in biomedical research owing to their specificity and potency. Many of these components exist in two genera of rattlesnakes, Crotalus and Sistrurus, with high toxicity and proteolytic activity variation.

Spatial Structure Explains Morphological Variation Better Than Climatic Gradients in the South American Rattlesnake (Crotalus durissus) [PDF]
Ecol EvolWe 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 ...

Complete Mitochondrial Genome of <i>Ovophis makazayazaya</i> (Viperidae, Crotalinae) and Phylogenetic Analysis. [PDF]
Ecol EvolThis study sequenced and annotated the complete 17,230 bp mitochondrial genome of Ovophis makazayazaya, which contains 13 protein‐coding genes (PCGs), 2 rRNAs, 22 tRNAs, and a D‐loop region, with a significant AT bias (57.2%). Phylogenetic analyses confirmed its placement within Crotalinae, and all PCGs showed evidence of purifying selection (Ka/Ks < 1)

Electrical field-induced contractions on Crotalus durissus terrificus and Bothrops jararaca aortae are caused by endothelium-derived catecholamine. [PDF]
PLoS ONE, 2018 Endothelium is the main source of catecholamine release in the electrical-field stimulation (EFS)-induced aortic contractions of the non- venomous snake Panterophis guttatus.

Guidelines for the diagnosis and differential diagnosis of snakebite envenoming of ruminants in Brazil [PDF]
Pesquisa Veterinária Brasileira, 2022 : In Brazil, snakebites are often cited as a cause of mortality in ruminants, but there are discrepancies in the literature regarding its actual prevalence, either by lack of diagnosis or by mistakes in the differential diagnosis.
