The absolute number of species in an assemblage or community.
The number of different species that exist within a given area of community.
the total number of native species within a particular region.
The number of species of organisms living in a region. (Contrast with species diversity.)
a number of species in a community
The simplest measure of biodiversity is species richness. Species richness scores are simple counts of the actual number of species in a given area. The areas considered richest are those with the most species. Therefore an African rainforest would be considered richer than a comparable area in the Sahara desert. more on species richness
A measure of biological diversity referring to the number of species in an area.
The number of species within a region. A term commonly used as a measure of species diversity, but technically only one aspect of diversity.
The number of different species found in a particular environment.
the total number of species in an area
the number of species of a particular interest group found in a given area
The number of species (taxa) present in a defined area or sampling unit.
The number of species present in a community.
The total number of species present. It expresses variety but not relative abundance (Wenger 1984).
The number of species occurring in a particular place (e.g., in an ecoregion).
The number of different species in a community or ecosystem.
the absolute number of species in a given area
Species richness is the simplest measure of biodiversity and is simply a count of the number of different species in a given area. It is referred to in equations as S.
