Abstract

The ambient temperature is a decisive factor in many activities of poikilothermic organisms, since it influences the correct development of their vital processes, which implies the existence of an optimal temperature range. The present study describes selected temperatures (Tsel) of R. spinulosa in adult individuals. For this purpose, adults of this species were acclimatized at 10°C and then subjected to a thermal gradient was used in the laboratory. The mean Tsel in the studied individuals was 23.38±2.65°C, with a range from 17.73°C to 28.93°C. Future surveys are suggested to determine the habitat thermal quality and thermoregulatory precision.
