The alpha diversity of ecologic communities is affected by many biotic and abiotic drivers
and, in turn, affects ecosystem functioning. Yet, patterns of alpha diversity in host-associated …

Hill numbers or the effective number of species are increasingly used to quantify species
diversity of an assemblage. Hill numbers were recently extended to phylogenetic diversity …

Spatial patterns of biodiversity are inextricably linked to their collection methods, yet no
synthesis of bias patterns or their consequences exists. As such, views of organismal …

One of the most fundamental questions in ecology is how many species inhabit the Earth.
However, due to massive logistical and financial challenges and taxonomic difficulties …

The gut microbiome profoundly affects human health and disease, and their infecting viruses
are likely as important, but often missed because of reference database limitations. Here, we …

We develop a novel class of measures to quantify sample completeness of a biological
survey. The class of measures is parameterized by an order q≥ 0 to control for sensitivity to …

Quantifying and assessing changes in biological diversity are central aspects of many
ecological studies, yet accurate methods of estimating biological diversity from sampling …

On the basis of the sampling data from an assemblage, estimation of species richness
(observed plus undetected) is statistically difficult especially for highly-diverse assemblages …

Plants are a hyperdiverse clade that plays a key role in maintaining ecological and
evolutionary processes as well as human livelihoods. Biases, gaps and uncertainties in …

We propose an integrated sampling, rarefaction, and extrapolation methodology to compare
species richness of a set of communities based on samples of equal completeness (as …
