Led description). Phylogenetic fuzzy weighting was performed inside the R environment (available at http:rproject.org), employing the package SYNCSA .three.2 ([5], obtainable at http:cran.rproject.orgwebpackagesSYNCSA). Pairwise phylobetadiversity involving plots was obtained by computing squaredrooted BrayCurtis dissimilarities (or other acceptable resemblance measure, see Legendre Anderson [52]) for every single pair of plots in matrix P (Table ). We adopted this approach to analyze phylobetadiversity because it enables to decompose phylogenetic gradients across an array of plots into orthogonal eigenvectors and, much more importantly, to evaluate which clades are related to each phylogenetic eigenvector [24]. We achieved this by performing a PCoA [53] according to the squarerooted BrayCurtis dissimilarities amongst pairs of plots previously computed on matrix P. Such procedure generatedPLOS One plosone.orgprincipal coordinates of phylogenetic structure (PCPS) for every floristic plot. Every PCPS is really a vector describing an orthogonal phylogenetic gradient in the dataset [8,23]. The PCPS with all the highest eigenvalue describes broader phylogenetic gradients related to the split with the deepest tree nodes across the dataset, for instance that connecting conifers and angiosperms. As the eigenvalues from the other PCPS reduce, finer phylogenetic gradients related to splits of shallower nodes (e.g. families, genera) are described [8]. By relating the correlation among species from big clades and also the PCPS eigenvectors, we can draw a scatterplot relating directly sites and species grouped in clades. PCPS evaluation was performed working with the package PCPS (available at http:cran.rproject.orgwebpackagesPCPS) on the R atmosphere (offered at http:rproject.org). Further, PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/23467991 we compared the forest kinds in relation towards the PCPS eigenvectors containing a lot more than 5 of total variation in matrix P utilizing oneway ANOVA. Pvalues had been obtained by a permutation test with 999 iterations [37]. Such analysis permitted us to define which phylogenetic gradients had been largely associated with distinctive Atlantic forest types. ANOVA was performed within the R environment (out there at http:rproject.org), applying package vegan 2.00 ([39], offered at http:cran.rproject.orgwebpackages vegan). Furthermore, we employed other 4 wellknown phylobetadiversity measures to compare the forest sorts inside the Southern Brazilian Atlantic Forest (see Table ). COMDIST is a phylobetadiversity measure that computes the mean phylogenetic distance among species occurring in two unique internet sites [44]. Because of this, this phylobetadiversity measure captures variation connected with all the a lot more basal nodes linking species [3]. Computing COMDIST values with out contemplating the variation in species abundances is equivalent to compute the phylogenetic distinctness (Rao’s D) proposed by Hardy Senterre [50]. As a result, we opted for making use of only the former in this study. However, by standardizing Rao’s D values by the imply withinsite phylogenetic diversity it truly is achievable to receive one more phylobetadiversity measure (Rao’s H, [50]), which captures phylobetadiversity patterns related to additional terminal nodes inside the tree [3]. COMDISTNT [44] measures the mean phylogenetic distance involving every single species inside a plot along with the nearest phylogenetic neighbor in a further internet site (Table ). It truly is, as a result, a “terminal node” metric [3]. The last phylobetadiversity system used in this study was UniFrac [49], which measures, for each and every pair of websites, the fraction.
