  2. Ecological niche - Wikipedia

    en.wikipedia.org/wiki/Ecological_niche

    It assumes that niche space is largely saturated with individuals and species, leading to strong competition. Niches are restricted because "neighbouring" species, i.e., species with similar ecological characteristics such as similar habitats or food preferences, prevent expansion into other niches or even narrow niches down.

  3. Hutchinson's rule - Wikipedia

    en.wikipedia.org/wiki/Hutchinson's_rule

    The rule's legitimacy has been questioned, as other categories of objects also exhibit size ratios of roughly 1.3. Studies done on interspecific competition and niche changes in Tits (Parus spp.) [4] show that when there are multiple species in the same community there is an expected change in foraging when they are of similar size (size ratio ...

  4. Vacant niche - Wikipedia

    en.wikipedia.org/wiki/Vacant_niche

    A vacant niche or empty niche is an ecological niche in a particular ecosystem that is not occupied by a particular species. The issue of what exactly defines a vacant niche and whether they exist in ecosystems is controversial. The subject is intimately tied into a much broader debate on whether ecosystems can reach equilibrium, where they ...

  5. Realized niche width - Wikipedia

    en.wikipedia.org/wiki/Realized_niche_width

    A species' realized niche is usually much narrower than its fundamental niche width as it is forced to adjust its niche around the superior competing species. The physical area where a species lives, is its habitat. The set of environmental features essential to that species' survival, is its "niche." (Ecology. Begon, Harper, Townsend)

  6. Competitive exclusion principle - Wikipedia

    en.wikipedia.org/wiki/Competitive_exclusion...

    Yellow adapts to a new niche restricted to the top and bottom and avoiding competition. In ecology , the competitive exclusion principle , [ 1 ] sometimes referred to as Gause's law , [ 2 ] is a proposition that two species which compete for the same limited resource cannot coexist at constant population values.

    The regulations appear to focus on chips called GPUs with the most powerful computing capabilities, a critical but niche market with only two meaningful players, Nvidia and AMD.

  8. Competition (biology) - Wikipedia

    en.wikipedia.org/wiki/Competition_(biology)

    The word "niche" refers to a species' requirements for survival and reproduction. These requirements include both resources (like food) and proper habitat conditions (like temperature or pH). Gause reasoned that if two species had identical niches (required identical resources and habitats) they would attempt to live in exactly the same area ...
