Reliable estimates of beta diversity with incomplete sampling

Ecology, 2018
AbstractBeta diversity, the compositional variation among communities or assemblages, is crucial to understanding the principles of diversity assembly. The mean pairwise proportional dissimilarity expresses overall heterogeneity of samples in a data set and is among the most widely used and most robust measures of beta diversity.

Patterns of elevational beta diversity in micro‐ and macroorganisms

Global Ecology and Biogeography, 2012
ABSTRACTAim  While ecologists have long been interested in diversity in mountain regions, elevational patterns in beta diversity are still rarely studied across different life forms ranging from micro‐ to macroorganisms. Also, it is not known whether the patterns in turnover among organism groups are affected by the degree to which the environment is ...

Local and regional drivers of turnover and nestedness components of species and functional beta diversity in lake macrophyte communities in China.

Science of the Total Environment, 2019
Beta diversity describes the variation in species composition between sites and is often influenced by both local and regional processes. Partitioning beta diversity into turnover (species replacement between sites) and nestedness (richness difference ...

Differently dispersing organism groups show contrasting beta diversity patterns in a dammed subtropical river basin.

Science of the Total Environment, 2019
Although it is widely known that dams can have large impacts on the environmental and biological characteristics of downstream rivers, there is a substantial lack of studies focusing on which ecological processes cause longitudinal changes in biological ...

A geometric approach to beta diversity

Ecological Monographs
AbstractBeta diversity—the variation among community compositions in a region—is a fundamental measure of biodiversity. Most classic measures have posited that beta diversity is maximized when each community has a distinct, nonoverlapping set of species.

Phylogenetic and Functional Beta Diversity

2013
The first objective of this chapter is to introduce the conceptual and empirical background for why phylogenetic and functional analyses of beta diversity are of interest to ecologists. This is followed by detailed instructions on how to calculate in R the major metrics of phylogenetic and functional beta diversity that are most commonly employed in ...

Beta diversity for functional ecology

2008
The utility of biodiversity measures that incorporate pairwise species functional differences is becoming increasingly recognized. Functional diversity is regarded as the key for linking community composition to ecosystem processes like productivity, nutrient cycling, carbon sequestration, or stability when subject to perturbations.
