Updates to betapart (from newest to oldest)

betapart 1.4 (2017-jan-24) New!

Version betapart 1.4 extends the partitioning framework to abundance-based multiple-site dissimilarity. The functions (betapart.core.abund, beta.pair.abund, beta.multi.abund, and beta.sample.abund) allow the decomposition of the multiple-site versions of Bray-Curtis and Ruzicka indices of dissimilarity into two separate components accounting for (i) the dissimilarity derived from balanced variation in abundance between sites, and (ii) the dissimilarity derived from unidirectional abundance gradients. The methods are fully described in Baselga 2017 (Methods Ecol. Evol.)

betapart 1.3 (2013-dec-12)

Version betapart 1.3 extends the partitioning framework to phylogenetic beta diversity. The functions (phylo.betapart.core, phylo.beta.pair, and phylo.beta.multi) allow the partition of the dissimilarity in phylogenetic composition between communities into a phylogenetic turnover and a phylogenetic nestedness-resultant component. This method is fully described in Leprieur et al. 2012 (PLoS ONE 7(8): e42760).

betapart 1.2 (2013-feb-12)

Version betapart 1.2 extends the partitioning framework to functional beta diversity. The functions (functional.betapart.core, functional.beta.pair, and functional.beta.multi) allow the partition of the dissimilarity in functional composition between communities into a functional turnover and a functional nestedness-resultant component. This method is fully described in Villeger et al. 2013 (Global Ecol. Biogeogr. 22: 671–681).

Moreover, version betapart 1.2 also provides an analogous partition for the pairwise abundance-based Bray-Curtis dissimilarity. The new function (bray.part) allows the decomposition of the popular Bray-Curtis index of dissimilarity into two separate components accounting for (i) the dissimilarity derived from balanced variation in abundance between sites, and (ii) the dissimilarity derived from unidirectional abundance gradients. This method is fully described in Baselga 2013 (Methods Ecol. Evol. 4: 552–557).
