Additive partitioning of a beta diversity index is controversial.
A recent study (1) reports the spatial clustering patterns of the global distribution of human infectious diseases. However, there are some controversial issues that arise from the beta diversity partitioning method used in the paper. To further debate these issues, we follow the same notations in the paper (1) by writing the Sorensen beta diversity index as βsor = ðb+ cÞ=ð2a+ b+ cÞ. Here, a is...
متن کاملReply to Chen and Schmera: Partitioning beta diversity into replacement and nestedness-resultant components is not controversial.
With reference to our recent paper addressing the global biogeography of human infectious diseases (1), Chen and Schmera (2) suggest that our method for evaluating beta diversity and its components is controversial. We used the method developed by Baselga (3) (hereafter, BAS framework) for partitioning compositional dissimilarity into replacement (turnover) and nestedness-resultant components. ...
متن کاملDiversity partitioning without statistical independence of alpha and beta.
Diversity partitioning has become a popular method for analyzing patterns of alpha and beta diversity. A recent evaluation of the method emphasized a distinction between additive and multiplicative partitioning and further advocated the use of multiplicative partitioning based on a presumed independence between alpha and beta. Concurrently, additive partitioning was criticized for producing dep...
متن کاملPartitioning diversity into independent alpha and beta components.
Existing general definitions of beta diversity often produce a beta with a hidden dependence on alpha. Such a beta cannot be used to compare regions that differ in alpha diversity. To avoid misinterpretation, existing definitions of alpha and beta must be replaced by a definition that partitions diversity into independent alpha and beta components. Such a unique definition is derived here. When...
متن کاملAdditive Diversity Partitioning of Fish in a Caribbean Coral Reef Undergoing Shift Transition
Shift transitions in dominance on coral reefs from hard coral cover to fleshy macroalgae are having negative effects on Caribbean coral reef communities. Data on spatiotemporal changes in biodiversity during these modifications are important for decision support for coral reef biodiversity protection. The main objective of this study is to detect the spatiotemporal patterns of coral reef fish d...
