Historical Legacies in World Amphibian Diversity Revealed by the Turnover and Nestedness Components of Beta Diversity
Historic processes are expected to influence present diversity patterns in combination with contemporary environmental factors. We hypothesise that the joint use of beta diversity partitioning methods and a threshold-based approach may help reveal the effect of large-scale historic processes on present biodiversity. We partitioned intra-regional beta diversity into its turnover (differences in ...
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 کاملGraphs whose edge set can be partitioned into maximum matchings
This article provides structural characterization of simple graphs whose edge-set can be partitioned into maximum matchings. We use Vizing’s classification of simple graphs based on edge chromatic index.
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 کاملRevealing Beta-Diversity Patterns of Breeding Bird and Lizard Communities on Inundated Land-Bridge Islands by Separating the Turnover and Nestedness Components
Beta diversity describes changes in species composition among sites in a region and has particular relevance for explaining ecological patterns in fragmented habitats. However, it is difficult to reveal the mechanisms if broad sense beta-diversity indices (i.e. yielding identical values under nestedness and species replacement) are used. Partitioning beta diversity into turnover (caused by spec...
