Taxonomic, functional, and phylogenetic beta diversity in the Inner Mongolia grassland

Global Ecology and Conservation, 2021
Beta diversity, which measures the variation in community composition along environmental gradients, has great significance for biodiversity conservation and nature reserve construction.

Disentangling niche theory and beta diversity change [PDF]

The American Naturalist, 2021
Abstract Beta diversity describes the differences in species composition among communities. Changes in beta diversity over time are thought to be due to selection based on species’ niche characteristics. For example, theory predicts that selection that favours habitat specialists will increase beta diversity.

Gamma diversity and under-sampling together generate patterns in beta-diversity [PDF]

Scientific Reports, 2021
Beta diversity represents how species in the regional pool segregate among local communities and hence forms a link between local and regional species diversities.

A phylogenetic approach identifies patterns of beta diversity and floristic subregions of the Qinghai-Tibet Plateau [PDF]

Plant Diversity
Patterns of taxonomic and phylogenetic beta diversity and their relationships with environmental correlates can help reveal the origin and evolutionary history of regional biota.

How does invasion degree shape alpha and beta diversity of freshwater fish at a regional scale? [PDF]

Ecology and Evolution, 2022
Freshwater ecosystems appear more vulnerable to biodiversity loss due to several anthropogenic disturbances and freshwater fish are particularly vulnerable to these impacts.

Global beta-diversity of angiosperm trees is shaped by Quaternary climate change. [PDF]

Sci Adv, 2023
As Earth’s climate has varied strongly through geological time, studying the impacts of past climate change on biodiversity helps to understand the risks from future climate change. However, it remains unclear how paleoclimate shapes spatial variation in

Dispersal limitation and environmental filtering effects: The taxonomic and functional beta diversity of ground beetles along the altitudinal gradient in Chinese warm‐temperature forests [PDF]

Ecology and Evolution
Beta diversity patterns along environmental gradients and underlying mechanisms constitute key research inquiries in biogeography. However, ecological processes often also influence the functional traits of biological communities, making the assessment ...

ANALYZING OR EXPLAINING BETA DIVERSITY? COMMENT [PDF]

Ecology, 2008
ion is alpha diversity, as in LBPa, rather than community composition, as in TR. In fact, alpha diversity is also level-1 data in the TR scheme. This is because alpha diversity can be presented in a sites 3 alpha diversity table, which is an observation units 3 descriptors table, which in turn is the basic format of level-1 data (Fig. 1).

Biotic homogenisation and differentiation as directional change in beta diversity: synthesising driver–response relationships to develop conceptual models across ecosystems

Biological Reviews of The Cambridge Philosophical Society, 2023
Biotic homogenisation is defined as decreasing dissimilarity among ecological assemblages sampled within a given spatial area over time. Biotic differentiation, in turn, is defined as increasing dissimilarity over time.

Community vertical stratification drives temporal taxonomic and phylogenetic beta diversity in a mixed broadleaf-conifer forest

Frontiers in Ecology and Evolution, 2023
Temporal change of beta diversity provides a better understanding of the extent and consequences of species composition in forest communities with the ongoing global climate change.
