Movement of Zooplankton in Diatom Gradients


Hardy and Gunther1 and Harvey et al.2 have proposed somewhat opposing hypotheses in explanation of a phenomenon widely observed in the sea, namely, an inverse correlation in catches of zooplankton and phytoplankton. Hardy's hypothesis, that of "animal exclusion", is supported in some degree by the experimental work of Lucas3; and Harvey's, of the "grazing effect of zooplankton", by various observations on rates of feeding, and statistically by Fleming4 and others.
