Abstract A simple analytical procedure to test for differences in beta diversity among sets of plots has been recently presented. Here, we describe an improved randomization procedure that replaces the one previously proposed. This procedure consists of shuffling within‐group dissimilarities among groups and disregarding between‐group

Influence of human land use and invasive species on beta diversity of tropical ant assemblages
Insect Conservation and Diversity, 2021Understanding how biodiversity is distributed is increasingly becoming important under ongoing and projected human land use. Measures of beta diversity, and its partitions, can offer insights for conservation and restoration of biodiversity.

Measuring beta‐diversity from taxonomic similarity
Journal of Vegetation Science, 2007AbstractQuestion: 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 ...

Beta-Diversity in Tropical Forest Trees
Science, 2002The 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.

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,

Partitioning multiple facets of beta diversity in a tropical stream macroalgal metacommunity
Journal of Biogeography, 2020We 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 NeurosciencesAbstract 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.

Environmental and spatial factors are broadly recognized as important predictors of beta diversity patterns. However, the scale at which beta diversity patterns are evaluated will affect the outcoming results.
