Interactive influence of biotic and abiotic cues on the plasticity of preferred body temperatures in a predator?prey system

Popis výsledku v původním jazyce

The ability to modify phenotypes in response to heterogeneity of the thermal environment represents an important component of an ectotherm?s non-genetic adaptive capacity. Despite considerable attention being dedicated to the study of thermally-induced developmental plasticity, whether or not interspeciWc interactions shape the plastic response in both a predator and its prey remains unknown. We tested several predictions about the joint inXuence of predator/prey scents and thermal conditions on the plasticity of preferred body temperatures (Tp) in both actors of this interaction, using a dragonXy nymphs?newt larvae system. DragonXy nymphs (Aeshna cyanea) and newt eggs (Ichthyosaura alpestris) were subjected to Xuctuating cold and warm thermal regimes(7?12 and 12?22°C, respectively) and the presence/absence of a predator or prey chemical cues. Preferred body temperatures were measured in an aquatic thermal gradient (5?33°C) over a 24-h period. Newt Tp increased with developmental temp
