Too Hot to Eat: Wild and Lab-Bred Lymnaea stagnalis 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) Lymnaea stagnalis, whereas the first-generation offspring of freshly collected wild (F1 D-strain) snails raised and maintained under similar laboratory conditions did not show any alterations. The W-strain snails might have inadvertently been selected against heat tolerance since they were first brought into the laboratory many (∼70) years ago. We also posit that the F1 D-strain snails do not perceive the heat shock as a sufficient stressor to alter their feeding response because their parental populations in wild environments have repeatedly experienced temperature fluctuations, thus becoming more tolerant and resilient to heat. The different responses exhibited by two strains of the same species highlight the importance of selecting the most appropriate strain for addressing questions about the impacts of global warming on organisms' physiology and behavior.
期刊介绍:
The Biological Bulletin disseminates novel scientific results in broadly related fields of biology in keeping with more than 100 years of a tradition of excellence. The Bulletin publishes outstanding original research with an overarching goal of explaining how organisms develop, function, and evolve in their natural environments. To that end, the journal publishes papers in the fields of Neurobiology and Behavior, Physiology and Biomechanics, Ecology and Evolution, Development and Reproduction, Cell Biology, Symbiosis and Systematics. The Bulletin emphasizes basic research on marine model systems but includes articles of an interdisciplinary nature when appropriate.
