Phylogenetic diversity and biodiversity indices on phylogenetic networks.
In biodiversity conservation it is often necessary to prioritize the species to conserve. Existing approaches to prioritization, e.g. the Fair Proportion Index and the Shapley Value, are based on phylogenetic trees and rank species according to their contribution to overall phylogenetic diversity. However, in many cases evolution is not treelike and thus, phylogenetic networks have been develop...
متن کاملBiological communities as interacting compartments: thermodynamic properties and diversity indices
Diversity indices provide simple and powerful metrics for assessing biological communities. Based on entropy measures, the approach considers statistical and thermodynamic inferences to deduce ecological patterns. However, concerns exist regarding the accuracy of diversity indices. Because relative quantities depend on the sorting of organisms (e.g., guilds and species) and their interactions, ...
متن کاملCombinatorial Scoring of Phylogenetic Networks
Construction of phylogenetic trees and networks for extant species from their characters represents one of the key problems in phylogenomics. While solution to this problem is not always uniquely defined and there exist multiple methods for tree/network construction, it becomes important to measure how well the constructed networks capture the given character relationship across the species. In...
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 کاملRelative Diversity Indices
Diversity indices are frequently applied in the form of ratios of absolute diversity to the maximum diversity possible. Regardless of whether the maximum diversity is defined to be limited by the number of species or by the number of individuals present, the resultant indices can be shown to possess mathematically undesirable qualities. All such indices, including equitability as measured by Pi...
