Energy density and variability in abundance of pigeon guillemot prey: Support for the quality-variability trade-off hypothesis
Michael A. Litzow, John F. Piatt, Alisa A. Abookire, Martin D. Robards
2004, Journal of Animal Ecology (73) 1149-1156
1. The quality-variability trade-off hypothesis predicts that (i) energy density (kJ g-1) and spatial-temporal variability in abundance are positively correlated in nearshore marine fishes; and (ii) prey selection by a nearshore piscivore, the pigeon guillemot (Cepphus columba Pallas), is negatively affected by variability in abundance. 2. We tested these predictions...
