niche -- n. The portion of the environment which a species occupies, defined in terms of the conditions under which an organism can survive, and may be affected by the presence of other competing organisms.
niche The biological role played by a species.
niche overlap The extent to which two species require similar resources; speci?es the strength of the competition between the two species.
Niche: A general term referring to the range of environmental space occupied by a species.
Niche overlap: An overlap in resource requirements by two species.

It is comparatively easy for a poikilotherm to accumulate enough energy to reproduce. Poikilotherms in the same ecological niche often have much shorter generations than homeotherms: weeks rather than years.
There aren't niches that exist in certain areas of the brain like the hippocampus where neurogenesis can occur.
FILLING DIFFERENT NICHES
As Charles Darwin traveled the world, he studied many bird species and saw how they were able fill specific ecological niches that allowed different species to survive.
The evolution of new species or sub- species to fill unoccupied ecological niches. Aerobe. A microorganism that grows in the presence of oxygen. See Anaerobe. Agarose gel electrophoresis.
Vicariant: Refers to species that occupy similar ecological niches but in geographic isolation from each other. Implies a phylogenetic relationship existing between the two species.
Ecological terminology ...
While there are undoubtedly many "niche" applications for high density hybridization arrays to de novo sequencing (e.g., increasing the read length from 500-700 bases to beyond 1 kb would be important in the assembly process), ...
The mammalian fauna of Australia is often cited as an example of this; marsupial mammals fill most of the equivalent niches that placentals fill in other ecosystems.
When two species share overlapping ecological niches, they may be forced into competition for the resource(s) of that niche. This interspecific competition is another density-dependent check on the growth of one or both populations.
The emergence of this strain as a health issue may be an example of exploitation of the bacterium of a new niche; the mass preparation of food.
He proposed that the ancestral finches who came to the islands, found no competitors or predators and that through adaptive radiation they came to occupy the variety of ecological niches on the islands.
Adaptive radiation. The evolution of new species or sub- species to fill unoccupied ecological niches.
Aerobe. A microorganism that grows in the presence of oxygen. See Anaerobe.
There are more species of animals, then in all the other kingdoms combined. From worms, to blue whales, to bald eagles, animals have evolved to fit a wide variety of niches.
And then third, and very important, natural selection operates upon, over those long time periods, the changes that occur, to result in emergence of species that have particular abilities to survive in a niche that the environment has provided.
