Soil is an immense habitat for diverse organisms across the tree of life, but just how many
organisms live in soil is surprisingly unknown. Previous efforts to enumerate soil biodiversity …

Despite substantial interest in the species diversity of the human microbiome and its role in
disease, the scale of its genetic diversity, which is fundamental to deciphering human …

Aims In ecology and conservation biology, the number of species counted in a biodiversity
study is a key metric but is usually a biased underestimate of total species richness because …

Fungi are highly important biotic components of terrestrial ecosystems, but we still have a
very limited understanding about their diversity and distribution. This data article releases a …

Objective Sample size in surveys with open-ended questions relies on the principle of data
saturation. Determining the point of data saturation is complex because researchers have …

Most eukaryotic organisms are arthropods. Yet, their diversity in rich terrestrial ecosystems is
still unknown. Here we produce tangible estimates of the total species richness of …

Background Biological communities are normally composed of a few abundant and many
rare species. This pattern is particularly prominent in microbial communities, in which most …

A guide to data collection, modeling and inference strategies for biological survey data using
Bayesian and classical statistical methods. This book describes a general and flexible …

A general binomial mixture model is proposed for the species accumulation function based
on presence–absence (incidence) of species in a sample of quadrats or other sampling …

Species abundance distributions (SADs) follow one of ecology's oldest and most universal
laws–every community shows a hollow curve or hyperbolic shape on a histogram with many …
