Microbial Diversity: Genetic Diversity Vs Functional Diversity
Diversity is the main descriptor of community structure and is a determining factor in the dynamics and function of ecological communities [1]. However, the latter implicitly differs based on the different types of organisms and their relative abundance within the community which is considered to be significant [2]. Research in microbial ecology focuses on the study of microbial community dynam...

متن کاملPhylogenetic diversity within seconds.
We consider a (phylogenetic) tree with n labeled leaves, the taxa, and a length for each branch in the tree. For any subset of k taxa, the phylogenetic diversity is defined as the sum of the branch-lengths of the minimal subtree connecting the taxa in the subset. We introduce two time-efficient algorithms (greedy and pruning) to compute a subset of size k with maximal phylogenetic diversity in ...
متن کاملPhylogenetic diversity–area curves
Phylogenetic diversity–area curves are analogous to species–area curves and quantify the relationship between the phylogenetic diversity of species assemblages and the area over which assemblages are sampled. Here, we developed theoretical expectations of these curves under different ecological and macroevolutionary processes. We first used simulations to generate curves expected under three ec...
متن کاملModelling phylogenetic diversity
The paper proposes a model for measuring and valuing biodiversity based on evolutionary information, called the phylogenetic tree model. While avoiding the strong restrictions of Weitzman’s [Quart. J. Econ. 107 (1992) 363] “cladistic” approach, the phylogenetic tree model retains much of the mathematical simplicity of the cladistic model. In particular, in the phylogenetic tree model the divers...
