Of your total branch length of phylogenetic tree that is exclusive
In the total branch length of phylogenetic tree that is exclusive to every site (Table ). Because additional basal nodes are most likely to be shared by most species, UniFrac captures phylobetadiversity patterns related to far more terminal nodes [3]. This PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/24367588 strategy is mathematically equivalent to the Jaccard index when a star phylogeny is deemed [49]. UniFrac offers very related (but not exactly comparable) final results when when compared with PhyloSor [3], which can be another wellknown phylobetadiversity measure [54]. For this reason, we opted for utilizing only the former. COMDIST, COMDISTNT and Rao’s H have been computed in the R environment (out there at http:rproject.org), utilizing the package picante .6 ([48], out there at http:cran.at.rproject.orgwebpackagespicante). UniFrac was computed employing the R package GUniFrac .0 (readily available at http:cran.rproject.orgwebpackagesGUniFracindex.html). We carried out Mantel tests [53] depending on Pearson correlations (999 permutations) to evaluate the association amongst pairwise phylobetadiversity values obtained from matrix P and each of the other strategies (COMDIST, COMDISTNT, UniFrac and Rao’s H). Moreover, we performed PERMANOVA with permutation test (999 iterations) [37,38] making use of each pairwise phylobetadiversity technique as resemblance measures, to compare diverse forest typesPhylobetadiversity in Brazilian Atlantic ForestTable .

Whenever a significant Pvalue was obtained for the general model, we performed pairwise contrast analysis to test which group differed from the others [34]. The significance of contrasts was also evaluated by permutation, in a similar way as in PERMANOVA [34].
