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. Therefore, when an animal uses different habitats at different stages, ontogenetic niche shifts have spatially spreading demographic impacts (e.g., [3-6]).
