摘　　要：Predation is a pervasive selection pressure,shaping morphological,physiological,and behavioral phenotypes of prey species.Recent studies have begun to examine how the effects of individual experience with predation risk shapes the use of publicly available risk assessment cues.Here,we investigated the effects of prior predation risk experience on disturbance cue production and use by Trinidadian guppies Poecilia reticulata under laboratory conditions.In our first experiment,we demonstrate that the response of guppies from a high predation population(Lopinot River)was dependent upon the source of disturbance cue senders(high vs.low predation populations).However,guppies collected from a low predation site(Upper Aripo River)exhibited similar responses to disturbance cues,regardless of the sender population.In our second experiment,we used laboratory strain guppies exposed to high versus low background risk conditions.Our results show an analogous response patterns as shown for our first experiment.Guppies exposed to high background risk conditions exhibited stronger responses to the disturbance cues collected from senders exposed to high(vs.low)risk conditions and guppies exposed to low risk conditions were not influenced by sender experience.Combined,our results suggest that experience with background predation risk significantly impacts both the production of and response to disturbance cues in guppies.
