Species richness | Definition, Examples, & Facts | Britannica
https://www.britannica.com/science/species-richness
Web ResultSpecies richness, the count, or total number, of unique species within a given biological community, ecosystem, biome, or other defined area. While species richness does not consider the population sizes of individual species in the area (see species abundance) or how even the distribution of each.

Species richness - Wikipedia
https://en.wikipedia.org/wiki/Species_richness
Web ResultSpecies richness is the number of different species represented in an ecological community, landscape or region. Species richness is simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions .

Species Richness - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/earth-and-planetary-sciences/species-richness
Web ResultSpecies richness (S) is the number of species within a defined region. The species richness of a region is obtained through sampling or via a census. Because “region” is defined by the observer, species richness has been further categorized into three components to account for changes in spatial scale.

Web ResultCommunities with the lowest species richness lie near the poles, which get less solar energy and are colder, drier, and less amenable to life. This pattern is illustrated below for mammalian species richness (species richness calculated only for mammal species, not for all species).

Web ResultFeb 9, 2021 · Ecologists may be attracted to species richness as a diversity metric because true richness depends only on the number of species, but not on their relative abundances. However, estimates of richness are, in fact, highly sensitive to the relative abundances of species in the community being sampled.

Web ResultSpecies richness and species evenness are probably the most frequently used measures of the total biodiversity of a region. Species diversity is also described in terms of the phylogenetic diversity, or evolutionary relatedness, of the species present in an area.

Web ResultJan 1, 2015 · Species richness is the simplest way to describe biotic community and regional diversity (Maguran, 1988 ). It refers to the number of species in an area, biotic community, or ecosystem. Species richness does not take into account the abundances of the species or their relative abundance distribution, but rather the …
