Activity pattern of Crotalus durissus (Viperidae, Crotalinae): Feeding, reproduction and snakebite
One hundred and seventy‐three adults and twenty‐six juveniles of Crotalus durissus were examined by removing the stomach contents and faecal material. Rattlesnakes were most active between April andExpand

Reproductive cycle of the Neotropical Crotalus durissus terrificus: I. Seasonal levels and interplay between steroid hormones and vasotocinase.
Crotaline snakes present delayed fertilization and sperm storage because secondary vitellogenesis is not completed by the time of mating. The release of vitellogenesis and synchrony between ovulationExpand

Phylogeographic patterns of trans-Amazonian vicariants and Amazonian biogeography: the Neotropical rattlesnake (Crotalus durissus complex) as an example
Aim  To investigate the phylogeography and execute a historical-demographic analysis of the Neotropical rattlesnake, Crotalus durissus, thereby testing the hypothesis of a Pleistocene central AmazonExpand

Morphological correlates of incipient arboreality and ornithophagy in island pitvipers, and the phylogenetic position of Bothrops insularis
Morphological differences between two semi-arboreal, bird-eating island pitvipers,Bothropsinsularis andGloydius shedaoensis, and their mainland relatives were investigated. Mitochondrial DNA sequenceExpand

Long-Term Sperm Storage in the Female Neotropical Rattlesnake Crotalus durissus terrificus ( Viperidae : Crotalinae )
This paper reports the muscular twisting and convolution of the uterus in Crotalus durissus terrificus as a strategy to store sperm over winter (long-term sperm storage). Aspects of the femaleExpand

Origin and phylogenetic position of the Lesser Antillean species of Bothrops (Serpentes, Viperidae): biogeographical and medical implications
We use mitochondrial DNA sequences to infer the origin and phylogenetic position of the Lesser Antillean species of the pitviper genus Bothrops , B. caribbaeus and B. lanceolatus . The two speciesExpand

Reproductive cycle of the Neotropical Crotalus durissus terrificus: II. Establishment and maintenance of the uterine muscular twisting, a strategy for long-term sperm storage.
Crotaline snakes store sperm by means of a uterine musculature twisting (UMT). We investigated the influence of plasma levels of estradiol and progesterone and vasotocinase cystine aminopeptidaseExpand
