Spatial Factors Play a Major Role as Determinants of Endemic Ground Beetle Beta Diversity of Madeira Island Laurisilva [PDF]

, 2013
The development in recent years of new beta diversity analytical approaches highlighted valuable information on the different processes structuring ecological communities.

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 ...

Components of beta diversity in hierarchical sampling designs: A new approach [PDF]

, 2013
Diversity partitioning has been generally used to estimate the contribution of different levels of sampling hierarchy to landscape diversity. However, beta diversity values derived by partitioning strongly depend on focus and sample size and the ...

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

Assembly mechanism of macroinvertebrate metacommunities and ecological factors of multiple aspects of beta diversity in a boreal river basin, China

Frontiers in Ecology and Evolution, 2023
The emergence of metacommunity theory has significantly contributed to our understanding of the drivers of community assembly and biome variation. The Network Location Hypothesis (NPH) posits that tributary communities situated at the source regions of a

Unimodal Relationships of Understory Alpha and Beta Diversity along Chronosequence in Coppiced and Unmanaged Beech Forests

Diversity, 2020
Patterns of diversity across spatial scales in forest successions are being overlooked, despite their importance for developing sustainable management practices. Here, we tested the recently proposed U-shaped biodiversity model of forest succession.

Potent in vitro and in vivo antifungal activity of a small molecule host defense peptide mimic through a membrane-active mechanism

Scientific Reports, 2017
Lethal systemic fungal infections of Candida species are increasingly common, especially in immune compromised patients. By in vitro screening of small molecule mimics of naturally occurring host defense peptides (HDP), we have identified several active ...

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.

Does functional soil microbial diversity contribute to explain within-site plant beta-diversity in an alpine grassland and a dehesa meadow in Spain? [PDF]

, 2017
Questions: Once that the effects of hydrological and chemical soil properties have been accounted for, does soil microbial diversity contribute to explain change in plant community structure (i.e. within-site beta-diversity)?

A temporal beta‐diversity index to identify sites that have changed in exceptional ways in space–time surveys

Ecology and Evolution, 2019
Aim This paper presents the statistical bases for temporal beta‐diversity analysis, a method to study changes in community composition through time from repeated surveys at several sites.
