Species richness is the number of different species represented in an ecological community, landscape or region. Species richness is simply a count of...

Species richness, or biodiversity, increases from the poles to the tropics for a wide variety of terrestrial and marine organisms, often referred to as...

Meanings of species diversity may include species richness, taxonomic or phylogenetic diversity, and/or species evenness. Species richness is a simple...

contains. For example, species richness (usually noted S) is simply the number of species, e.g. at a particular site. Richness is a simple measure, so...

is a technique to assess species richness from the results of sampling. Rarefaction allows the calculation of species richness for a given number of individual...

estimating abundance. Species evenness is combined with species richness, (the number of species in the community), in order to determine species diversity, which...

diversity of microorganisms in soda lakes is very high, with species richness (number of species present) of individual lakes often rivaling that of freshwater...

Relative species abundance and species richness describe key elements of biodiversity. Relative species abundance refers to how common or rare a species is...

the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area...

An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological...

geographically with each other regarding endemism and species richness. Especially using mammals as flagship species proved to be a poor system of identifying and...

world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward...

disturbance and species diversity. IDH is based on the following premises: First, ecological disturbances have major effects on species richness within the...

replace the more clearly-defined and long-established terms, species diversity and species richness. Other definitions include (in chronological order): An...

body size-species richness distribution is a pattern observed in the way taxa are distributed over large spatial scales. The number of species that exhibit...

mineral-rich water into a fen changes the water chemistry, which can alter species richness and dry out the peat. Drier peat is more easily decomposed and can...

increases (assuming no other species are simultaneously lost). Similarly, when species become extinct, species richness decreases, once again assuming...

introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a...

some phytoplankton models predict an increase in species richness, or the number of different species within a given area. This increase in plankton diversity...

construction. Species richness is usually measured to determine the effect of a dam on the ecosystem surrounding it. To observe the species richness, scientists...

In conservation biology, a flagship species is a species chosen to raise support for biodiversity conservation in a given place or social context. Definitions...

taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness, species richness, and species diversity...

regarding ecosystems include species richness, biomass of productivity and stability/resistant to change. When a species is added or removed from an ecosystem...

scientific literature, r-selected species are occasionally referred to as "opportunistic" whereas K-selected species are described as "equilibrium". In...
