Webontogenetic niche shift. The ecological feedback is incorporated by explicitly taking resource dynamics into account. We assume that individuals exploit one prey type when they are small and another prey type when they are big. The ontogenetic niche shift is 190 Claessen and Dieckmann WebAbstract. The transition to piscivory is a crucial ontogenetic niche shift for many primarily piscivorous fishes. An early transition to piscivory may increase growth, decrease mortality, and therefore enhance lifetime fitness. Although much is known about the extent and causes of variation in the timing of the shift to piscivory among species ...

Webontogenetic niche shift [1], [2]. A key aspect of ontogenetic niche shift is that it divides a population into distinct life-history stages that have different trophic effects on food webs.
