The Elevational Gradient of Bird Beta Diversity in the Meili Snow Mountains, Yunnan Province, China [PDF]

Animals, 2023
Understanding the elevational patterns of beta diversity in mountain regions is a long-standing problem in biogeography and ecology. Previous research has generally focused on the taxonomy facet on a large scale, but was limited with regard to multi ...

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.

Drivers of desert plant beta diversity on the Qinghai–Tibet plateau [PDF]

Ecology and Evolution
The desert ecosystem of the Qinghai–Tibet Plateau (QTP) is an important component of China's desert ecosystem. Studying the mechanisms shaping the taxonomic, phylogenetic, and functional beta diversity of plant communities in the QTP desert will help us ...

Seaweeds in two oceans: beta-diversity [PDF]

Frontiers in Marine Science, 2017
Several species assembly mechanisms have been proposed to structure ecological communities. We assess the biogeography of seaweeds along 2,900 km of South Africa’s coastline in relation to a thermal gradient produced by the Agulhas Current, and ...

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.

Taxonomic dependency of beta diversity for bacteria, archaea, and fungi in a semi-arid lake [PDF]

Frontiers in Microbiology, 2022
Microbial beta diversity has been recently studied along the water depth in aquatic ecosystems, however its turnover and nestedness components remain elusive especially for multiple taxonomic groups.

An attribute‐diversity approach to functional diversity, functional beta diversity, and related (dis)similarity measures [PDF]

Ecological Monographs, 2019
Based on the framework of attribute diversity (a generalization of Hill numbers of order q), we develop a class of functional diversity measures sensitive not only to species abundances but also to trait‐based species‐pairwise functional distances.

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.

Natural succession and clearcutting as drivers of environmental heterogeneity and beta diversity in North American boreal forests. [PDF]

PLoS ONE, 2018
Clear-cutting alters natural ecosystem processes by reducing landscape heterogeneity. It is the dominant harvesting technique across the boreal zone, yet understanding of how environmental heterogeneity and beta diversity are structured in forest ...

Genotypic-Phenotypic Diversity in Beta Thalassemia

Mediterranean Journal of Hematology and Infectious Diseases, 2014
The remarkable variability in clinical severity of the thalassemia reflects both genetic and environmental factors. It is becoming apparent that the genetic element involves many loci, some of which are directly involved with the basic defect in globin ...
