Shannon richness

Webb13.2.1 Species Richness This is the oldest and the simplest concept of species diversity - the number of species in the community or the region. McIntosh (1967) coined the name species richness to describe this concept. The basic measurement problem is that it is often not possible to enumerate all of the species in a natural community or region, Webb8 maj 2024 · The Shannon diversity index (a.k.a. the Shannon–Wiener diversity index) is a popular metric used in ecology.
