Species divergence and the measurement of microbial diversity

WebAbstract: We developed a theoretical framework based on phylogenetic comparative methods to integrate phylogeny into three measures of biodiversity: species variability, … Web1 mei 2002 · Phylogenetic diversity (PD) is a biodiversity measure that takes account of phylogenetic relationships (hence evolutionary history) between taxa. It may therefore provide a better currency for conservation evaluation than taxonomic richness. Here, we demonstrate that, contrary to recent assertions, optimisation tools can be used to … laundry room with mud room area pics

WebAbstract. The discovery of small 142 Nd anomalies in early Archean rocks has brought about a revolution in our understanding of early planetary differentiation processes. 142 Nd is a radiogenic isotope produced by the decay of now-extinct 146 Sm in crustal and mantle reservoirs. Given that 142 Nd heterogeneities can be produced only prior to 4. ... Web- 4 - future option values – require phylogenetic diversity measures that incorporate species importance values. Rao’s quadratic entropy Q (Rao 1982), a generalization of the Gini-Simpson index, was the first diversity measure that accounts for both phylogeny and species abundances. Webphylogenetic diversity quantify the difference. Differences among species can be characterized by measuring any number of traits, such as body size and shape, … laundry room with office
