WebSundblad et al. 2014). By definition, nursery habitats promote greater densities, faster growth rates, and/or higher survival than other habitats, and thus provide a greater contribution of juveniles to the adult por-tion of populations (Beck et al. 2001). Many species exhibit an ontogenetic shift between different habitats as they develop. Two ... 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 insects and a few groups of vertebrates, especially fish and amphibians, where … Ver mais
WebGuill (2009) also investigated the effects of an ontogenetic shift in habitat or diet for a consumer population that in the juvenile stage exploits a different resource than during adulthood. He modeled consumer dynamics using the same stage-structured biomass model that we have used in this and previous chapters.

Web26 de dez. de 2024 · Furthermore, the ontogenetic shift in the root/shoot ratio indicates shifts in the balance between water uptake and carbon acquisition in individuals, in addition to shifts in whole-plant structures and functions. The capacity for water uptake and carbon acquisition at the individual level from seedlings to mature trees needs elucidation.

Web5. Ontogenetic shifts in ecological strategies appear to have been selected as a re-sponse to ontogeny-dependent filters. Thus, strategies that favour less costly leaves and faster growth rates (relatively R-selected) in juveniles shift towards C and/or S strategies in adulthood, depending on habitat productivity. Nevertheless,
