Phylogeography of the Central American lancehead Bothrops asper (SERPENTES: VIPERIDAE)
The uplift and final connection of the Central American land bridge is considered the major event that allowed biotic exchange between vertebrate lineages of northern and southern origin in the New World. However, given the complex tectonics that shaped Middle America, there is still substantial controversy over details of this geographical reconnection, and its role in determining biogeographi...
متن کاملMorphological variation in the lancehead pitviper Bothrops asper (Garman) (Serpentes: Viperidae) from Middle America.
Variation of morphological characters in the pitviper Bothrops asper (Garman) was studied in terms of scutellation, color patterns, and landmark measures for 374 Middle American specimens. Gender, ontogeny, and geographic effects were examined for each character. In this species, females are larger than males and have more ventral and dorsal rows, and can be distinguished by some landmark varia...
متن کاملPostprandial thermogenesis in Bothrops moojeni (Serpentes: Viperidae)
Snakes that can ingest prey that are proportionally large have high metabolic rates during digestion. This great increase in metabolic rate (specific dynamic action – SDA) may create a significant augment in the animal’s body temperature. The present study investigated postprandial thermogenesis in Bothrops moojeni. Briefly, two groups of snakes were fed meals equivalent to 17 ± 3% and 32 ± 5% ...
متن کاملSexual dimorphism in venom of Bothrops jararaca(Serpentes: Viperidae).
Bothrops jararaca is an abundant snake in Brazil, and its venom has been studied exhaustively. The species exhibits adult size dimorphism in which female are larger. We registered the growth in Snout-Vent Length and weight of one litter (with 11 females and 12 males). We compared growth curves and venom profile between male and female of B. jararaca in order to establish the relationship of tho...
