Rarefaction of beta diversity [PDF]

open access: yesEcological Indicators, 2019
Beta diversity has long been used to summarize the amount of variation in species composition among a set of N sampling units. However, while classical beta diversity provides an estimate of multiple-site dissimilarity among all sampling units, it is not informative on the changes of multiple-site dissimilarity as a function of sampling effort.

Turnover Drives High Benthic Macroinvertebrates’ Beta Diversity in a Tropical Karstic Lake District

open access: yesDiversity, 2022
Beta diversity is useful to explain community assembly across landscapes with spatial variation. Its turnover and nestedness components help explain how beta diversity is structured across environmental and spatial gradients.

Drivers of beta diversity in modern and ancient reef-associated soft-bottom environments [PDF]

open access: yesPeerJ, 2020
Beta diversity, the compositional variation among communities, is often associated with environmental gradients. Other drivers of beta diversity include stochastic processes, priority effects, predation, or competitive exclusion.

Relative importance of deterministic and stochastic processes for beta diversity of bird assemblages in Yunnan, China

open access: yesEcosphere, 2021
Evaluating the relative importance of deterministic and stochastic processes underlying taxonomic and functional beta diversity is crucial in community ecology, because it can reveal the dominant processes of community assembly.

Fine-scale bacterial beta diversity within a complex ecosystem (Zodletone Spring, OK, USA): the role of the rare biosphere. [PDF]

open access: yesPLoS ONE, 2010
BackgroundThe adaptation of pyrosequencing technologies for use in culture-independent diversity surveys allowed for deeper sampling of ecosystems of interest. One extremely well suited area of interest for pyrosequencing-based diversity surveys that has

Environmental filtration and dispersal limitation explain different aspects of beta diversity in desert plant communities

open access: yesGlobal Ecology and Conservation, 2022
Environmental filtration and spatial processes are associated with variation in ecological communities and biodiversity; however, their relative importance to species beta diversity at different sampling scales has not been fully explored in desert plant

N90, a Diversity Index Sensitive to Variations in Beta Diversity Components [PDF]

open access: yesDiversity, 2021
Species diversity in a community is mainly related to the number and abundance of species that form it. N90 is a recently developed diversity index based on the results of the similarity percentage (SIMPER) analysis that represents the number of species contributing up to ninety percent of within-group similarity in a group of samples.

Undersampling and the measurement of beta diversity

open access: yesMethods in Ecology and Evolution, 2013
Summary Beta diversity is a conceptual link between diversity at local and regional scales. Various additional methodologies of quantifying this and related phenomena have been applied. Among them, measures of pairwise (dis)similarity of sites are particularly popular. Undersampling, i.e.

Ecological drivers of taxonomic, functional, and phylogenetic beta diversity of macroinvertebrates in Wei River Basin of northwest China

open access: yesFrontiers in Ecology and Evolution
Understanding biodiversity changes, along with its driving factors and mechanisms, is crucial in biogeography and community ecology. Beta diversity is an indicator for discerning the compositional variations among communities and is essential role in ...
