Postprandial 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 کاملMicrurus ibiboboca (Serpentes, Elapidae) is not a Guiana Shield Species
( ) Coral snakes (Micrurus) are a diverse group of Neotropical squamates. Similarities in morphology and coloration can make identification difficult, especially in areas of species sympatry. Species with triad-type coloration, approximately 30% of all Micrurus species, are among the most difficult to identify. Micrurus ibiboboca Merrem, 1820 is an east Brazilian species with triad-type colorat...
متن کاملPhylogeography 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...
