Conservation evaluation and phylogenetic diversity

Biological Conservation, 1992
Protecting biological diversity with limited resources may require placing conservation priorities on different taxa. A system of priorities that reflects the value of taxonomic diversity can be achieved by setting priorities such that the subset of taxa that is protected has maximum underlying feature diversity. Such feature diversity of taxon subsets

Modelling phylogenetic diversity

Resource and Energy Economics, 2004
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,

Using functional and phylogenetic diversity to infer avian community assembly along elevational gradients

Global Ecology and Biogeography, 2019
Aim: We present the first global analysis of elevational gradients in functional and phylogenetic diversity of birds and test for signals of deterministic processes (i.e., environmental filtering and limiting similarity) in community assembly.

The global loss of avian functional and phylogenetic diversity from anthropogenic extinctions

Science
Humans have been driving a global erosion of species richness for millennia, but the consequences of past extinctions for other dimensions of biodiversity—functional and phylogenetic diversity—are poorly understood.

Relative reduction of biological and phylogenetic diversity of the oral microbiota of diabetes and pre-diabetes patients.

Microbial Pathogenesis, 2019
BACKGROUND A reciprocal relationship between oral health and systemic disease, such as type 2 diabetes, has been suggested, whereby a systemic disease is a predisposing factor for oral infection.

High phylogenetic diversity among corticioid homobasidiomycetes

Mycological Research, 2004
Homobasidiomycetes display a variety of fruit body morphologies. Examples include gilled mushrooms, coral fungi, polypores and puffballs but also species with simple crust-like basidiomata, usually called corticioid fungi. The latter group has largely been neglected in recent studies of homobasidiomycete evolution.

Phylogenetic diversity of termite gut spirochaetes

Environmental Microbiology, 1999
A molecular phylogenetic analysis was done of not‐yet‐cultured spirochaetes inhabiting the gut of the termite, Reticulitermes flavipes (Kollar). Ninety‐eight clones of near‐full‐length spirochaetal 16S rDNA genes were classified by ARDRA pattern and by partial sequencing.

Computing Phylogenetic Diversity for Split Systems

IEEE/ACM Transactions on Computational Biology and Bioinformatics, 2008
In conservation biology it is a central problem to measure, predict, and preserve biodiversity as species face extinction. In 1992 Faith proposed measuring the diversity of a collection of species in terms of their relationships on a phylogenetic tree, and to use this information to identify collections of species with high diversity.

Phylogenetic Diversity of LHRH

1987
Early studies suggested mammalian hypothalamic luteinizing hormonereleasing hormone (here referred to as gonadotropin-releasing hormone (GnRH)) was a unique molecular form, but research over the past eight years established that there is considerable diversity in the structure of the corresponding releasing hormone in other species.
