Relative Abundance Distribution Information
In the field of ecology, the relative abundance distribution (RAD) is a graph of the number of species observed in a field study as a function of their observed abundance. The graphs obtained in this manner are typically fitted to a Zipf-Mandelbrot law, the exponent of which serves as an index of biodiversity in the ecosystem under study.[1]
