Beta-Diversity in Tropical Forest Trees

Science, 2002
The high alpha-diversity of tropical forests has been amply documented, but beta-diversity—how species composition changes with distance—has seldom been studied. We present quantitative estimates of beta-diversity for tropical trees by comparing species composition of plots in lowland terra firme forest in Panama, Ecuador, and Peru.

A review of beta diversity studies

Biodiversity Science, 2010
Beta diversity is an important component of biological diversity, measuring compositional change in species assemblages across temporal and spatial scales. Beta diversity concerns not only a number of ecological and evolutionary issues, but can also guide the selection of protected areas and help to optimize conservation networks.

Partitioning multiple facets of beta diversity in a tropical stream macroalgal metacommunity

Journal of Biogeography, 2020
We evaluated different facets of beta diversity (taxonomic, phylogenetic and functional), and its components (spatial turnover and nestedness), of a stream macroalgal metacommunity, as well as the effect of local environmental variables, types of biome ...

Diversity of amyloid beta peptide actions

Reviews in the Neurosciences
Abstract Fibril formation by amyloidogenic proteins and peptides is considered the cause of a number of incurable diseases. One of the most known amyloid diseases is Alzheimer’s disease (AD). Traditionally, amyloidogenic beta peptides Aβ40 and Aβ42 (Aβs) are considered as main causes of AD and the foremost targets in AD fight.

The drivers of multiple dimensions of stream macroinvertebrate beta diversity across a large montane landscape

Limnology and Oceanography, 2020
Environmental filtering and spatial processes have been associated with variation in ecological communities and biodiversity; however, their relative importance on multiple dimensions of beta diversity has not been fully explored in montane streams. Here,

Damming affects riverine macroinvertebrate metacommunity dynamics: Insights from taxonomic and functional beta diversity.

Science of the Total Environment, 2020
Understanding ecological processes that drive metacommunity dynamics is essential for elucidating the mechanisms of community assembly and for guiding biodiversity conservation. This is especially important in dammed rivers.

Local environmental factors influence beta diversity patterns of tropical fish assemblages more than spatial factors.

Ecology, 2019
A major goal in ecology is to understand mechanisms that influence patterns of biodiversity and community assembly at various spatial and temporal scales.

Land use effect on butterfly alpha and beta diversity in the Eastern Himalaya, India

, 2020
Conservation of biodiversity in agroecosystems is a global challenge as conversion of forest to agroecosystems has been one of the major causes for biodiversity loss through habitat transformation.

Measuring beta‐diversity from taxonomic similarity

Journal of Vegetation Science, 2007
AbstractQuestion: The utility of beta (β‐) diversity measures that incorporate information about the degree of taxonomic (dis)similarity between species plots is becoming increasingly recognized. In this framework, the question for this study is: can we define an ecologically meaningful index of β‐diversity that, besides indicating simple species ...
