| Abstract: | Inducible responses in prey to predation risk can influence species interaction strength, with significant ecological consequences. Much of the past research on interactions in aquatic ecosystems has focused on remote stimuli (e.g., diffusible chemicals emitted from predators and injured conspecifics, which easily propagate through environmental water), as cues triggering trait responses in prey, and has overlooked the importance of proximate stimuli (e.g., physical disturbance and less-diffusible chemicals), which occur in attack or direct contact to prey by predators. Proximate stimuli from predators as well as remote stimuli may induce significant responses in prey functional traits such as behavior, morphology, and life history and, therefore, act as an important mechanism of top-down effects in aquatic ecosystems. In this opinion paper, we argue that studying the effects of proximate stimuli is essential to better understanding of individual adaptation to predation risk in nature and ecological consequences of predator-prey interactions. Here, we propose research directions to examine the role of proximate stimuli for phenotypic plasticity and interaction systems. |
