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

Diversity, 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.

Changes in woody species beta diversity in forest communities reveal conservation priorities in the southeastern Qinghai-Tibet Plateau

Global Ecology and Conservation, 2023
Studying spatiotemporal changes in beta diversity and its drivers yields meaningful information to promote nature conservation. In this study, we surveyed tree and shrub species diversity in 107 historical plots in the southeastern Qinghai-Tibet Plateau.

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

Frontiers 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 ...

Microbial and metabolic succession on common building materials under high humidity conditions. [PDF]

, 2019
Despite considerable efforts to characterize the microbial ecology of the built environment, the metabolic mechanisms underpinning microbial colonization and successional dynamics remain unclear, particularly at high moisture conditions. Here, we applied

Undersampling and the measurement of beta diversity

Methods 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.

A comparative analysis reveals weak relationships between ecological factors and beta diversity of stream insect metacommunities at two spatial levels. [PDF]

, 2015
The hypotheses that beta diversity should increase with decreasing latitude and increase with spatial extent of a region have rarely been tested based on a comparative analysis of multiple datasets, and no such study has focused on stream insects.

Empirical evaluations between beta-diversity, environmental heterogeneity, and spatial extent among multiple taxonomic groups [PDF]

Acta Limnologica Brasiliensia
Aim Beta diversity is expected to increase due to environmental heterogeneity and spatial extent. However, it remains unknown whether the response of beta diversity to these variables is consistent among different taxonomic groups. I investigated whether

High resolution vegetation assessment with beta-diversity - a moving window approach [PDF]

, 2011
Monitoring designs are often suffering from the inherent non-stationarity of the monitored systems. To overcome this limition, we propose a sampling designs based on high resolution mapping and spatial analyses with double spatial scaling process ...

Diet Diversity Is Associated with Beta but not Alpha Diversity of Pika Gut Microbiota [PDF]

Frontiers in Microbiology, 2016
Wild mammals often consume different food sources as they become geographical available. This change in diet composition is likely to influence the gut microbial community, yet it remains unclear what the relationship looks like-particularly in small herbivores-under natural conditions.

Biodiversity assessment in incomplete inventories: leaf litter ant communities in several types of Bornean rain forest.

PLoS ONE, 2012
Biodiversity assessment of tropical taxa is hampered by their tremendous richness, which leads to large numbers of singletons and incomplete inventories in survey studies.
