Non-Consumptive Effects of Cannibalism Elicit a Metabolic Response in Dragonfly Larvae.

ABSTRACT: Predator-prey interactions typically involve changes in metabolic rates associated with hunting, foraging, and activation/maintenance of defense mechanisms. Similar response can result from non-consumptive effects mediated by chemical cues, such as alarm cues (indicating predation), diet cues (signaling food resources), and kairomones (indicating predator or prey availability). While the impact of interspecific chemical communication on energy expenditure is well-studied, the role of conspecific chemical cues is less understood. This study examines non-consumptive effects of cannibalism on metabolic rates in dragonfly larvae (Sympetrum sanguineum). During the respiratory experiment, larvae were exposed to low and high concentrations of conspecific kairomones and kairomones with cues
