Ecologists have long been intrigued by the fact that small-scale species richness can vary substantially among WebSpecies richness is the number of different species that occurs in a defined area. In practice, estimates of species richness (or any other metric of species diversity) are typically restricted to a particular taxonomic group (e.g., trees and mammals), or a particular trophic level (e.g., primary producers and herbivores). WebBiodiversity, Species Richness, and Relative Species Abundance. Biodiversity describes a community’s biological complexity: it is measured by the number of different species (species richness) in a particular area and their relative abundance (species evenness).
