Though usually considered separately, predation and parasitism are parallel consumer-resource interactions. Both predators and parasites can reduce victim fitness, regulate victim populations, and alter interactions between victims and other members of the community. Recent studies suggest that, like predators, parasites might even shape ecosystem structure and function through their top-down effects. However, despite these similarities, theory developed to study predator-prey interactions must be applied judiciously when studying parasite-host interactions, due to inherent differences between consumer types. For example, parasites attack a single host per life stage, whereas predators consume multiple prey individuals during each life stage. Predators are immediately lethal to their victims, whereas parasites are not. Parasites share an intimate and durable interaction with their victims, whereas predators do not. Parasites are usually smaller than their hosts, whereas predators are usually larger than their prey. Finally, on average, parasites are more host-specific than predators are prey-specific. Speakers in this session will use concepts, tools, and frameworks from predator-prey theory to illuminate parasite-host interactions, making explicit comparisons between predation and parasitism. Topics to be covered include direct (consumptive and nonconsumptive) and indirect (density-mediated and trait-mediated) effects, behavioral responses of victims, consumer-resource models, metabolic theory, food webs, and conservation. Speakers will highlight recent advances at the intersection of predator-prey and parasite-host ecology, thereby contributing to a general consumer-resource framework.
