Formal Links between Feature Diversity and Phylogenetic Diversity [PDF]

open access: yesSystematic Biology, 2020
Abstract The extent to which phylogenetic diversity (PD) captures feature diversity (FD) is a topical and controversial question in biodiversity conservation. In this short paper, we formalize this question and establish a precise mathematical condition for FD (based on discrete characters) to coincide with PD.

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

open access: yes, 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]

open access: yes, 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.

An interchange property for the rooted Phylogenetic Subnet Diversity on phylogenetic networks

open access: yesJournal of Mathematical Biology, 2023
Abstract Faith’s Phylogenetic Diversity (PD) on rooted phylogenetic trees satisfies the so-called strong exchange property that guarantees that, for every two sets of leaves of different cardinalities, a leaf can always be moved from the largest set to the smallest in such a way that the sum of the PD values does not decrease.

Eggshell pigment composition covaries with phylogeny but not with life history or with nesting ecology traits of British passerines [PDF]

open access: yes, 2015
No single hypothesis is likely to explain the diversity in eggshell coloration and patterning across birds, suggesting that eggshell appearance is most likely to have evolved to fulfill many nonexclusive functions.

Functional diversity of Himalayan bat communities declines at high elevation without the loss of phylogenetic diversity

open access: yesScientific Reports, 2021
Species richness exhibits well-known patterns across elevational gradients in various taxa, but represents only one aspect of quantifying biodiversity patterns.

Geo-Distribution Patterns of Soil Fungal Community of Pennisetum flaccidum in Tibet

open access: yesJournal of Fungi, 2022
Pennisetum flaccidum can be used as a pioneer species for the restoration of degraded grasslands and as a high-quality forage for local yak and sheep in alpine regions.

A Note on Encodings of Phylogenetic Networks of Bounded Level [PDF]

open access: yes, 2009
Driven by the need for better models that allow one to shed light into the question how life's diversity has evolved, phylogenetic networks have now joined phylogenetic trees in the center of phylogenetics research. Like phylogenetic trees, such networks

Variation in species diversity and functional traits of sponge communities near human populations in Bocas del Toro, Panama [PDF]

open access: yesPeerJ, 2015
Recent studies have renewed interest in sponge ecology by emphasizing the functional importance of sponges in a broad array of ecosystem services.

A Bayesian phylogenetic hidden Markov model for B cell receptor sequence analysis. [PDF]

open access: yes, 2019
The human body generates a diverse set of high affinity antibodies, the soluble form of B cell receptors (BCRs), that bind to and neutralize invading pathogens.
