| Description
| - 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 temperature irrespective of the presence/absence of predator cues. In dragonXies, thermal reaction norms for Tp were aVected by the interaction between temperature and prey cues. SpeciWcally, the presence of newt scents in cold regime lowered dragonXy Tp. We concluded that predator–prey interactions inXuenced thermally-induced plasticity of Tp but not in a reciprocal fashion. The occurrence of frequency-dependent thermal plasticity may have broad implications for predator–prey population dynamics, the evolution of thermal biology traits, and the consequences of sustaining climate change within ecological communities.
