Measuring temporal change in alpha diversity: A framework integrating taxonomic, phylogenetic and functional diversity and the iNEXT.3D standardization

open access: yesMethods in Ecology and Evolution, 2021
Biodiversity is a multifaceted concept covering different levels of organization from genes to ecosystems. Biodiversity has at least three dimensions: (a) Taxonomic diversity (TD): a measure that is sensitive to the number and abundances of species.

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.

Past and future of a century old Citrus tristeza virus collection: a California citrus germplasm tale. [PDF]

open access: yes, 2013
Citrus tristeza virus (CTV) isolates collected from citrus germplasm, dooryard and field trees in California from 1914 have been maintained in planta under quarantine in the Citrus Clonal Protection Program (CCPP), Riverside, California. This collection,

On opportunities and threats to conserve the phylogenetic diversity of Neotropical palms

open access: yesDiversity and Distributions: A journal of biological invasions and biodiversity, 2020
Palms are an ecologically and societally important plant group, with high diversity in the Neotropics. Here, we estimated the impacts of future climate change on phylogenetic diversity (PD) of Neotropical palms under varying climatic and dispersal ...

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

Agriculturally dominated landscapes reduce bee phylogenetic diversity and pollination services

open access: yesScience, 2019
Ancestral history matters Biodiversity is sometimes quantified purely by the number of species within a system that allow it to function to produce ecosystem services. Grab et al. show that simple species counting is too simplistic.
