In situ predatory behavior of Mysis relicta in Lake Michigan

Abstract: Selectivity coefficients (W') and predation rates on Lake Michigan zooplankton were determined for Mysis relicta during spring through fall using an in situ method. W' values indicated the following ranked order of prey preference: Cladocera > copepod copepodites and copepod nauplii > adult diaptomids and cyclopoids. With few exceptions, W' values for different prey categories remained fairly constant despite greatly changing relative abundances of prey. Predation rates and prey selectivity were similar in mos… Show more

“…This is because, at night, Mysis migrate up from the hypolimnion and lower metalimnion, into the upper metalimnion and lower epilimnion. D. mendotae have been shown to simultaneously migrate away from the regions inhabited by Mysis to higher regions in the epilimnion (Bowers and Vanderploeg 1982 (Clarke and Bennet 2003) and Flathead Lake, Montana (Spencer et al 1999).…”

“…In aquatic systems, predation risk is believed to be an important factor in determining the vertical position of many species in the water column (Zaret and Suffern 1976, Bowers and Vanderploeg 1982, Ohman et al 1983, Hayes 2003. Predation provides a strong selective force on behavior, and many species respond to environmental cues, migrate according to diel cycles, or respond to changes in light level, in a manner that reduces spatial overlap with visual predators.…”
