Too Hot to Eat: Wild and Lab-Bred Differ in Feeding Response Following Repeated Heat Exposure.

AbstractAcute extreme heat events are increasing in frequency and intensity. Understanding their effects on ectothermic organisms' homeostasis is both important and urgent. In this study we found that the exposure to an acute heat shock (30 °C for 1 hour) repeated for a seven-day period severely suppressed the feeding behavior of laboratory-inbred (W-strain) , whereas the first-generation offspring of freshly collected wild (F D-strain) snails raised and maintained under similar laboratory conditions did not show any alterations.
