Webdistinct (containing no species in common) to about 1 (Morisita 1959b, p. 69, 75) when the samples are identical with respect to proportional species composition. Morisita's formula can be simplified by use of an estimate of A appropri-ate for a model of sampling with replacement, rather than that given by Simpson.

WebWhen α < 1 and β < 1, the PG index is less affected than the Morisita-Horn index by the overlap of the most abundant species, whereas the opposite is true when α > 1 and β > 1. It follows that, similarly to the Renyi entropy, the PG index puts more weight on rare or abundant species, depending on the values of the parameters α , β . WebMorisita, Horn--Morisita, Binomial, Cao and Chao indices should be able to handle different sample sizes (Wolda 1981, Krebs 1999, Anderson & Millar 2004), and Mountford (1962) and Raup-Crick indices for presence--absence data should be able to handle unknown (and variable) sample sizes. Most of these indices are discussed by Krebs (1999) and ...

WebAug 29, 2024 · The Morisita–Horn index assesses the similarity between sample sets. It ranges from 0 (no common species between the two samples) to 1 (all species are equally present in the two samples).

WebThe Morisita-Horn index is a popular angular overlap measure used both in ecological and immunological literature. It quantifies overlap as cosine of an angle between two standardized population vectors. It ranges between zero (no overlap) and one (perfect overlap). MH tends to be over-sensitive to abundant species. For details see Rempala and …
