“…Several authors have reported that motion increases visual conspicuousness of zooplankton (Ware 1973, Kislalioglu & Gibson 1976, Janssen 1982, Wright & O'Brien 1982, Dodson et al 1995, Brewer & Coughlin 1996, O'Keefe et al 1998. The littoral fishes used as predators in these investigations make use of a saltatory search, alternating between swimming short distances and looking for moving prey while remaining stationary (O'Brien et al 1986, 1989, Evans & O'Brien 1988.…”

Abstract-Geophysical and ecological dynamics within lakes of the McMurdo Dry Valleys, Antarctica, are controlled by the presence of permanent ice covers. Despite the importance of the permanent ice cover, there have been no studies that have examined specific couplings between changes in the geophysical properties of the ice covers and dynamic ecological processes within the underlying water column. Herein we present seasonal irradiance and primary production data from Lake Bonney, Taylor Valley, and we show that the phenomena of ''ice whitening'' is caused by changes in the scattering properties within the upper meter of the ice column and that the timing and extent of this phenomena exerts a predominant constraint on primary production and overall phytoplankton dynamics.

“…This shift in diet preference appears to be active predator choice, however, and not the result of crowding behavior in Diaptomus. Feeding rates of planktivorous fish may also be affected by crowding behavior, since faster swimming prey are more visually conspicuous to fish (Wright and O'Brien 1982).…”

Mirrors are used to reflect two orthogonal views of a small aquarium into the lens of a single video camera, thus creating distortion‐free, three‐dimensional images. Zooplankton motion is quantified with computer software that categorizes different zooplankton behaviors and measures parameters such as distance, duration, angle of movement, and overall swimming speed. Using this system, we have found a strong behavioral response of Diaptomus minutus to the presence of conspecifics; Diaptomus greatly increases swimming speed and frequency of jumps under moderately crowded conditions.
