  2. Dominance (ecology) - Wikipedia

    en.wikipedia.org/wiki/Dominance_(ecology)

    Ecological dominance is the degree to which one or several species have a major influence controlling the other species in their ecological community (because of their large size, population, productivity, or related factors) [1] or make up more of the biomass. Both the composition and abundance of species within an ecosystem can be affected by ...

    Dominant species may mean: Dominant species (ecology), one of a small number of species which dominate in an ecological community; Dominant Species (novel) ...

  4. Diversity index - Wikipedia

    en.wikipedia.org/wiki/Diversity_index

    A diversity index is a method of measuring how many different types (e.g. species) there are in a dataset (e.g. a community).Diversity indices are statistical representations of different aspects of biodiversity (e.g. richness, evenness, and dominance), which are useful simplifications for comparing different communities or sites.

    Ecologically distinct species, on the other hand, have a much larger effect. Similarly, dominant species have a large effect on ecosystem function, while rare species tend to have a small effect. Keystone species tend to have an effect on ecosystem function that is disproportionate to their abundance in an ecosystem. [11]: 324

A biological rule which states that two species cannot coexist in the same environment if they are competing for exactly the same resource, often memorably summarized as "complete competitors cannot coexist". coniferous forest One of the primary terrestrial biomes, culminating in the taiga. conservation biology The study of Earth's biodiversity with the aim of protecting and ...

  8. Competitive exclusion principle - Wikipedia

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

    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. When one species has even the slightest advantage over another, the one with the advantage will dominate in the long term.

  9. Intermediate disturbance hypothesis - Wikipedia

    [2] [3] [4] Second, interspecific competition results in one species driving a competitor to extinction and becoming dominant in the ecosystem. [2] [3] [4] Third, moderate ecological scale disturbances prevent interspecific competition. [2] [3] [4] The hypothesis is ambiguous with its definitions of the terms "intermediate" and "disturbance".
