Distribution of phylogenetic diversity under random extinction.
Phylogenetic diversity is a measure for describing how much of an evolutionary tree is spanned by a subset of species. If one applies this to the unknown subset of current species that will still be present at some future time, then this 'future phylogenetic diversity' provides a measure of the impact of various extinction scenarios in biodiversity conservation. In this paper, we study the dist...
متن کاملFast Phylogenetic Biodiversity Computations Under a Non-uniform Random Distribution
Computing the phylogenetic diversity of a set of species is an important part of many ecological case studies. More specifically, let T be a phylogenetic tree, and let R be a subset of its leaves representing the species under study. Specialists in ecology want to evaluate a function f(T , R) (a phylogenetic measure) that quantifies the evolutionary distance between the elements in R. But, in m...
متن کاملOptimizing phylogenetic diversity under constraints.
Phylogenetic diversity (PD) is a measure of the extent to which different subsets of taxa span an evolutionary tree, and provides a quantitative tool for studying biodiversity conservation. Recently, it was shown that the problem of finding subsets of taxa of given size to maximize PD can be efficiently solved by a greedy algorithm. In this paper, we extend this earlier work, beginning with a m...
متن کاملDistribution of branch lengths and phylogenetic diversity under homogeneous speciation models.
The constant rate birth-death process is a popular null model for speciation and extinction. If one removes extinct and non-sampled lineages, this process induces 'reconstructed trees' which describe the relationship between extant lineages. We derive the probability density of the length of a randomly chosen pendant edge in a reconstructed tree. For the special case of a pure-birth process wit...
متن کاملPhylogenetic diversity, functional trait diversity and extinction: avoiding tipping points and worst-case losses.
The phylogenetic diversity measure, ('PD'), measures the relative feature diversity of different subsets of taxa from a phylogeny. At the level of feature diversity, PD supports the broad goal of biodiversity conservation to maintain living variation and option values. PD calculations at the level of lineages and features include those integrating probabilities of extinction, providing estimate...
