Consider a stochastic abundance model in which the species arrive in the sample according
to independent Poisson processes, where the abundance parameters of the processes …

How many kinds are there? Suppose that a population is partitioned into C classes. In many
situations interest focuses not on estimation of the relative sizes of the classes, but on …

We wish to estimate the total number of classes in a population based on sample counts,
especially in the presence of high latent diversity. Drawing on probability theory that …

The rRNA approach is the principal tool to study microbial diversity, but it has important biases.
These include polymerase chain reaction (PCR) primers bias, and relative inefficiency of …

We report a ribosomal tag pyrosequencing study of the phylogenetic diversity of Archaea,
Bacteria and Eucarya over a depth profile at the Hawaii Ocean Time-Series Station, ALOHA. …

High animal and plant richness in tropical rainforest communities has long intrigued naturalists.
It is unknown if similar hyperdiversity patterns are reflected at the microbial scale with …

Microbial diversity and distribution are topics of intensive research. In two companion papers
in this issue, we describe the results of the Cariaco Microbial Observatory (Caribbean Sea, …

Microorganisms are spectacularly diverse phylogenetically, but available estimates of their
species richness are vague and problematic. For example, for comparable environments, the …

Purpose To assess if adolescent dating violence was associated with physical intimate partner
violence victimization in adulthood, using a comprehensive propensity score to create a …

Over the past 100 years, Arctic temperatures have increased at almost twice the global average
rate. One consequence is the acceleration of glacier retreat, exposing new habitats that …
