More Information
Summary:Zooplankton populations in the field display morphological, physiological and behavioral changes as strategies to diminish predation pressure from both invertebrates and vertebrates (Kerfoot and Sih, 1987). Experimental studies on prey-predator interactions have shown that such changes can be induced by the presence of a predator (or chemicals produced by a predator) (Lass and Spaak, 2003). Although such alterations are known to occur in several zooplankton genera, the genus Daphnia has been the most thoroughly studied (Tollrian and Dodson, 1999).
