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

open access: yesScientific 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]

open access: yesPlant 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.

ANALYZING OR EXPLAINING BETA DIVERSITY? COMMENT [PDF]

open access: yesEcology, 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).

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

open access: yesFrontiers 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.

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

open access: yesGlobal 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]

open access: yesThe 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.

Different responses of incidence-weighted and abundance-weighted multiple facets of macroinvertebrate beta diversity to urbanization in a subtropical river system

open access: yesEcological Indicators, 2022
Urbanization is one of the major drivers of biotic homogenization (i.e., decrease in beta diversity) in freshwater systems. However, only a few studies have simultaneously examined how urbanization affects multiple facets (i.e., taxonomic, functional and

Putting beta-diversity on the map: broad-scale congruence and coincidence in the extremes. [PDF]

open access: yesPLoS Biology, 2007
Beta-diversity, the change in species composition between places, is a critical but poorly understood component of biological diversity. Patterns of beta-diversity provide information central to many ecological and evolutionary questions, as well as to ...

Effects of environment and metacommunity delineation on multiple dimensions of stream fish beta diversity

open access: yesFrontiers in Ecology and Evolution, 2023
IntroductionBeta diversity represents changes in community composition among locations across a landscape. While the effects of human activities on beta diversity are becoming clearer, few studies have considered human effects on the three dimensions of ...

Functional and taxonomic beta diversity of butterfly assemblages in an archipelago: relative importance of island characteristics, climate, and spatial factors

open access: yesEcological Indicators, 2022
Islands host a disproportionate fraction of global biodiversity and provide ideal systems for investigating the factors affecting patterns of biodiversity. However, islands are also vulnerable systems and epicenters of biodiversity loss.
