Postprandial thermogenesis in Bothrops moojeni (Serpentes: Viperidae)
Provedor de dados: Journal of Venomous Animals and Toxins Including Tropical Diseases
Autores: Stuginski,DR; Fernandes,W; Tattersall,GJ; Abe,AS.
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% of their body weight and were observed for 72 hours, in which thermal images of each snake were taken with an infrared camera in a thermostable environment with a constant air temperature of 30°C. The results showed a significant increase in snake surface temperature, with a thermal peak between 33 and 36 hours after feeding. The meal size had a great impact on the...

Circadian pattern of Bothrops moojeni in captivity (Serpentes: Viperidae)
Provedor de dados: Journal of Venomous Animals and Toxins Including Tropical Diseases
Autores: Stuginski,DR; Sant'Anna,SS; Fernandes,W; Abe,AS.
Members of the subfamily Crotalinae are considered to be essentially nocturnal and most of the data about these snakes have been collected from the field. Information on how nutritional status affects the movement rate and activity patterns is a key point to elucidating the ecophysiology of snakes. In this study, we distributed 28 lancehead Bothrops moojeni into three groups under distinct feeding regimens after a month of fasting. Groups were divided as follows: ingestion of meals weighing (A) 40%, (B) 20%, or (C) 10% of the snake body mass. Groups were monitored for five days before and after food intake and the activity periods and movement rates were recorded. Our results show that B. moojeni is prevalently nocturnal, and the activity peak occurs in...
