Ontogenetic niche shift
Ontogenetic niche shift (abbreviated ONS) is an ecological phenomenon where an organism (usually an animal) changes its diet or habitat during its ontogeny (development). During the ontogenetic niche shifting an ecological niche of an individual changes its breadth and position. The best known … Ver mais The ontogenetic niche shift is thought to be determined genetically, while also being irreversible. In complex natural systems the ONS happens multiple times in lifetime of an individual (in some examples the ontogenetic niche … Ver mais For communities It is thought that almost every organism shows some kind of ontogenetic niche shift. The ONS, which is responsible for causing a noticeable Ver mais • Life history theory • Niche differentiation • Alternative stable state Ver mais Even though the occurrence of ontogenetic niche shifting is thought to be widely distributed, the best known representative taxa with extensively studied ONS are … Ver mais Web20 de dez. de 2024 · Applying this multi-variate approach to 2,272 individuals from 13 taxonomic and functional distinct species (Amphibia, Hemiptera, Coleoptera, Odonata) sampled in natural pond communities allowed me to: (1) describe and quantify the diversity of trophic niche shift patterns over ontogeny in multi-dimensional space, and (2) identify …
