“…In contrast, Perca pose a large threat to all instars of D. mendotae because they, like Bythotrephes, are not limited by the relatively large size of D. mendotae (Fulford et al 2006). Finally, if D. mendotae are adaptively using predatorspecific cues, rather than relying on the similarity of cue of other predators to respond to Bythotrephes as our results suggest, we would expect Bythotrephes, a visually hunting, shallow-dwelling predator to induce the opposite vertical response than Mysis, a tactile-hunting, deepdwelling predator induces, which is what was observed here and in a previous study (Peacor et al 2005).…”

Abstract. Lack of shared evolutionary history reduces the expectation that native prey will detect and respond to invasive predators. Four mechanisms may explain the adaptive response that is nevertheless seen in various systems: prey may perceive the invasive predator through cue similarity with preexisting predators, cues of conspecifics eaten by the invasive predator, a learned response based on experience with the invasive predator (e.g., cue association), and cues from the invasive predator that are specific to it. We performed laboratory experiments in which zooplankton (Daphnia mendotae) responded adaptively to the zooplanktivore Bythotrephes longimanus (migrating downward), showed no response to taxonomically similar predatory cladocerans, and responded adaptively to more taxonomically distant native fish (migrating downward) and native shrimp (migrating upward). Conspecific cues associated with Bythotrephes predation actually reduced the response of D. mendotae to Bythotrephes. Combined with previous experiments that rule out learning, our experiments rule out the first three mechanisms above, demonstrating that D. mendotae respond to cues specific to and produced directly by Bythotrephes. This finely tuned response may be retained from an ancestral species that coevolved with Bythotrephes in its native range, or may have rapidly evolved due to strong selection by the invasive predator.

“…Gal et al (2004) hypothesized that M. relicta's avoidance of sharp thermal gradients may represent either a direct response to the change in temperature near the thermocline or a response to increasing fish kairomones encountered in warmer waters. High predator densities in upper waters have been shown to influence the position of vertically migrating zooplankton in the water column (Loose 1993;De Meester and Cousyn 1997;Peacor et al 2005). If this leads to movement into lower temperatures, it can result in lower overall growth rates of migratory invertebrates (Moore et al 1996;Fiksen 1997).…”

The extent to which temperature, temperature gradients, predator smell, and prey availability influence the migratory behaviors and vertical distribution of the opossum shrimp, Mysis relicta, was explored through controlled laboratory experiments and comparisons with field distributions of mysids in Lake Ontario. By varying environmental conditions in 2-m tall experimental columns in a temperature-controlled room, we determined that mysids prefer temperatures between 6uC and 8uC with limited movement into waters of 12uC or higher. No mysids moved into waters above 16uC in the absence of prey. However, a higher proportion of mysids moved into temperatures of 14uC and 16uC (but not 18uC) when densities of Daphnia pulicaria exceeding 120 L 21 were present at those temperatures. Mysis avoided waters with kairomones from a primary mysid predator, the alewife (Alosa pseudoharengus). The rate of temperature change with depth did not restrict mysid movements. A temperature preference function based on the experimental data was applied to an existing model of mysid vertical distribution. The modified model predicted the depth of maximum mysid density to within 1 m and yielded high percentage overlap index values when compared with published mysid vertical distributions in Lake Ontario. Our approach may be used to model how diurnal, seasonal, and larger climactic changes can impact both the vertical position and feeding ecology of mysids, a keystone species in many deep-water pelagic food webs.
