Phylogenetic Resolution and Quantifying the Phylogenetic Diversity and Dispersion of Communities
Conservation biologists and community ecologists have increasingly begun to quantify the phylogenetic diversity and phylogenetic dispersion in species assemblages. In some instances, the phylogenetic trees used for such analyses are fully bifurcating, but in many cases the phylogenies being used contain unresolved nodes (i.e. polytomies). The lack of phylogenetic resolution in such studies, whi...
متن کاملQuantifying Phylogenetic Beta Diversity: Distinguishing between ‘True’ Turnover of Lineages and Phylogenetic Diversity Gradients
The evolutionary dissimilarity between communities (phylogenetic beta diversity PBD) has been increasingly explored by ecologists and biogeographers to assess the relative roles of ecological and evolutionary processes in structuring natural communities. Among PBD measures, the PhyloSor and UniFrac indices have been widely used to assess the level of turnover of lineages over geographical and e...
متن کاملMitochondrial Diversity and Phylogenetic Structure of Marghoz Goat Population
The genetic diversity and phylogenetic structure was analyzed in Marghoz goat population by mitochondrial DNA sequences. Phylogenetic analysis was carried out using hyper variable region 1 (968 bp) obtained form 40 animals. Marghoz goat proved to be extremely diverse (average haplotype diversity of 0.999) and the nucleotide diversity values 0.022. A total of 40 Marghoz goats were grouped into s...
متن کاملOpposing phylogenetic diversity gradients of plant and soil bacterial communities.
Plants and soil microbes show parallel patterns of species-level diversity. Diverse plant communities release a wider range of organics that are consumed by more microbial species. We speculated, however, that diversity metrics accounting for the evolutionary distance across community members would reveal opposing patterns between plant and soil bacterial phylogenetic diversity. Plant phylogene...
متن کاملIn situ phylogenetic structure and diversity of wild Bradyrhizobium communities.
Bacteria often infect their hosts from environmental sources, but little is known about how environmental and host-infecting populations are related. Here, phylogenetic clustering and diversity were investigated in a natural community of rhizobial bacteria from the genus Bradyrhizobium. These bacteria live in the soil and also form beneficial root nodule symbioses with legumes, including those ...
