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...
