Species packing and the latitudinal gradient in beta-diversity [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2020
Abstract The decline in species richness at higher latitudes is among the most fundamental patterns in ecology. Whether changes in species composition across space (beta-diversity) contribute to this gradient of overall species richness (gamma-diversity) remains hotly debated.

Consequences of hydrological alteration for beta diversity of fish assemblages at multiple spatial scales

, 2021
Effects of dam operation and extraction of water from rivers on spatial variation in hydrological regimes, and consequences for freshwater biodiversity, are widely predicted but seldom assessed empirically. Evidence of linkages between hydrology and beta

An operational, additive framework for species diversity partitioning and beta‐diversity analysis [PDF]

Journal of Ecology, 2007
Summary An important goal of community ecology is the assessment of factors that are likely to influence the spatio‐temporal distribution of species assemblages and diversity. Surprisingly, most statistical methods devoted to this have remained poorly interconnected, as well as poorly connected with the popular metrics of diversity estimation.

Functional Diversity Plays a Role in Driving Beta-Diversity-Or Does It?

, 2018
Patrick and Brown (2018) suggest that functional diversity of the species pool has an important role in generating beta-diversity. Using a combination of path analysis and model selection, they ostensibly provide support for this hypothesis; however ...

Global variation in the beta diversity of lake macrophytes is driven by environmental heterogeneity rather than latitude [PDF]

, 2017
Aim: We studied global variation in beta diversity patterns of lake macrophytes using regional data from across the world. Specifically, we examined 1) how beta diversity of aquatic macrophytes is partitioned between species turnover and nestedness ...

Fast Computations for Measures of Phylogenetic Beta Diversity

PLOS ONE, 2016
For many applications in ecology, it is important to examine the phylogenetic relations between two communities of species. More formally, let [Formula: see text] be a phylogenetic tree and let A and B be two samples of its tips, representing the examined communities.

MBI: an R package for calculating multiple-site beta diversity indices [PDF]

, 2013
Beta diversity is one of most important features in community ecology. Indices for pairwise comparison of beta diversity have been extensively developed, but the ones specifically designed for multiple-site comparison of beta diversity are still limited.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Beta Diversity of Stream Fish Communities: Partitioning Variation Between Abiotic and Spatial Factors [PDF]

, 2016
Variation in species composition of assemblages within a region is known as beta diversity. Beta diversity contributes to regional diversity (gamma), and understanding the factors that maintain it and explain variation of it are necessary for conserving ...
