  3. Measurement of biodiversity - Wikipedia

    en.wikipedia.org/wiki/Measurement_of_biodiversity

    Biodiversity is usually plotted as the richness of a geographic area, with some reference to a temporal scale. Types of biodiversity include taxonomic or species, ecological, morphological, and genetic diversity. Taxonomic diversity, that is the number of species, genera, family is the most commonly assessed type. [7]

    v is the speciation rate in the model Relative species abundances in the UNTB model follow a zero-sum multinomial distribution. [ 19 ] The shape of this distribution is a function of the immigration rate, the size of the sampled community (grid), and θ . [ 19 ]
