First insights into the phylogenetic diversity of Mycobacterium tuberculosis in Nepal [PDF]

, 2012
BACKGROUND: Tuberculosis (TB) is a major public health problem in Nepal. Strain variation in Mycobacterium tuberculosis may influence the outcome of TB infection and disease. To date, the phylogenetic diversity of M.

Incongruent Spatial Distribution of Taxonomic, Phylogenetic, and Functional Diversity in Neotropical Cocosoid Palms

Frontiers in Forests and Global Change, 2021
Biodiversity can be quantified by taxonomic, phylogenetic, and functional diversity. Current evidence points to a lack of congruence between the spatial distribution of these facets due to evolutionary and ecological constraints.

Optimizing phylogenetic diversity under constraints [PDF]

Journal of Theoretical Biology, 2007
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.

Phylogenetic diversity of the Rickettsiae [PDF]

Journal of Bacteriology, 1989
Small subunit rRNA sequences have been determined for representative strains of six species of the family Rickettsiaceae: Rickettsia rickettsii, Rickettsia prowazekii, Rickettsia typhi, Coxiella burnetii, Ehrlichia risticii, and Wolbachia persica. The relationships among these sequences and those of other eubacteria show that all members of the family ...

Seasonal Variations in Plant Species Diversity and Phylogenetic Diversity in Abandoned Farmland of China’s Huang–Huai Plain

Diversity, 2023
Amidst urbanization and industrialization in China, abandoned farmland plays a crucial role in safeguarding plant diversity within agricultural landscapes. This study aimed to examine the patterns of seasonal variation in plant diversity within abandoned

Changes in taxonomic and phylogenetic diversity in the Anthropocene

Proceedings of the Royal Society B, 2020
To better understand how ecosystems are changing, a multifaceted approach to measuring biodiversity that considers species richness (SR) and evolutionary history across spatial scales is needed.

Effects of phylogenetic reconstruction method on the robustness of species delimitation using single-locus data [PDF]

, 2014
1. Coalescent-based species delimitation methods combine population genetic and phylogenetic theory to provide an objective means for delineating evolutionarily significant units of diversity.

A generalized framework for analyzing taxonomic, phylogenetic, and functional community structure based on presence-absence data [PDF]

, 2018
Community structure as summarized by presence–absence data is often evaluated via diversity measures by incorporating taxonomic, phylogenetic and functional information on the constituting species.

The metagenomics of biosilicification: causes and effects [PDF]

, 2008
In order to determine the links between geochemical parameters controlling the formation of silica sinter in hot springs and their associated microbial diversity, a detailed characterisation of the waters and of in situ-grown silica sinters was combined ...

Expanded Phylogenetic Diversity and Metabolic Flexibility of Mercury-Methylating Microorganisms

mSystems, 2020
Accurately assessing the production of bioaccumulative neurotoxic methylmercury by characterizing the phylogenetic diversity, metabolic functions, and activity of methylators in the environment is crucial for understanding constraints on the mercury ...
