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 کاملThe additive partitioning of species diversity: recent revival of an old idea
Ecologists have traditionally viewed the total species diversity within a set of communities as the product of the average diversity within a community (alpha) and the diversity among the communities (beta). This multiplicative concept of species diversity contrasts with the lesser known idea that and -diversities sum to give the total diversity. This additi e partitioning of species di ersity ...
متن کاملPartitioning Species Diversity across Landscapes and Regions: A Hierarchical Analysis of a, b, and g Diversity
Species diversity may be additively partitioned within and among samples (a and b diversity) from hierarchically scaled studies to assess the proportion of the total diversity (g) found in different habitats, landscapes, or regions. We developed a statistical approach for testing null hypotheses that observed partitions of species richness or diversity indices differed from those expected by ch...
متن کاملAdditive Partitioning of Species Diversity across Multiple Spatial Scales: Implications for Regional Conservation of Biodiversity
Ecologists and conservation biologists are keenly interested in how patterns of species diversity change across spatial scales. We examined how additive partitioning can be used to statistically evaluate spatial patterns of species diversity and develop conservation strategies. We applied additive partitioning to data on arboreal beetle diversity (richness, Shannon, Simpson) collected from a ne...
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...
