Because biodiversity is multidimensional and scale‐dependent, it is challenging to estimate
its change. However, it is unclear (1) how much scale‐dependence matters for empirical …

Current interest and debate on pollen-assemblage richness as a proxy for past plant
richness have prompted us to review recent developments in assessing whether modern …

Integrons are flexible gene-exchanging platforms that contain multiple cassettes encoding
accessory genes whose order is shuffled by a specific integrase. Integrons embedded within …

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 …

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 …

As part of national biosecurity programs, cargo imports, passenger baggage, and
international mail are inspected at ports of entry to verify compliance with phytosanitary …

Species richness (the number of species) in an assemblage is a key metric in many
research fields of ecology. Simple counts of species in samples typically underestimate the …

Paleobiologists are reaching a consensus that biases in diversity curves, origination rates,
and extinction rates need to be removed using statistical estimation methods. Diversity …

Globalization and economic growth are recognized as key drivers of biological invasions.
Alien species have become a feature of almost every biological community worldwide, and …

Clones are the fundamental building blocks of immune repertoires. The number of different
clones relates to the diversity of the repertoire, whereas their size and sequence diversity …
