Homogeneity of multivariate dispersions
Web16 sep. 2024 · For instance, Malavasi et al. showed that functional diversity (i.e., the amount of species distinctiveness in a community expressed as species richness multiplied by funcional evenness and mean trait dispersion) and evenness (i.e., the homogeneity in the abundance distribution of traits in a community) decreased respectively with the increase … WebA homogeneity of multivariate dispersions indicated that these parameters also differed significantly between the NE and SE coasts, with a marked dissimilarity between the beaches studied. Our results will contribute to a better understanding of the biodiversity and biomass of beach-cast seaweeds for possible future economic use (e.g. as fertilizer) in …
