Partitioning multiple facets of beta diversity in a tropical stream macroalgal metacommunity
(2020-08-01)
Aim: 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 ...
Patterns of species turnover in plant-pollinator communities along a precipitation gradient in Patagonia (Argentina)
(Wiley Blackwell Publishing, Inc, 2009-12)
Recent studies have assessed the influence of different types of gradients (e.g. altitudinal, latitudinal and temporal, among others) on the structure and function of community-level plant-pollinator webs. Although the ...
Stochastic species loss and dispersal limitation drive patterns of spatial and temporal beta diversity of fish assemblages in tropical agroecosystem streams
(2020-01-01)
Beta diversity quantifies changes in assemblages among sites and can identify how anthropogenic changes affect species distributions patterns. We investigated how spatial and temporal beta diversity of fish assemblages ...
Beta Diversity of Plant-Pollinator Networks and the Spatial Turnover of Pairwise Interactions
(Public Library Science, 2014-11-10)
Interactions between species form complex networks that vary across space and time. Even without spatial or temporal constraints mutualistic pairwise interactions may vary, or rewire, across space but this variability is ...
The importance of local environmental, hydrogeomorphological and spatial variables for beta diversity of macrophyte assemblages in a Neotropical floodplain
(Wiley Blackwell Publishing, Inc, 2019-02)
Questions: Understanding the processes that determine the variation in community composition (β-diversity) is a major challenge in ecology, evolution, and conservation. Here we assess the importance of abiotic variables ...
Macrofaunal assemblages associated with coralline turf: Species turnover and changes in structure at different spatial scales
(Inter-Research, 2008-07)
Our aim was to analyse changes in species turnover and structure of macrofaunal assemblages associated with intertidal coralline algal turfs at 4 spatial scales along the coast of Argentina (southwestern Atlantic): provinces ...
Bird diversity along a gradient of fragmented habitats of the Cerrado
(Acad Brasileira De Ciencias, 2018-03-01)
Understanding the factors that affect biodiversity is of central interest to ecology, and essential to species conservation and ecosystems management. We sampled bird communities in 17 forest fragments in the Cerrado biome, ...
Turnover, richness difference and nestedness of rodent assemblages along the southern Andes elevation gradient
(Wiley Blackwell Publishing, Inc, 2021-04)
Beta diversity in ecological communities can reflect adaptations of species to differences in climate, environmental characteristics and site history, as well as local ecological dynamics. These dissimilarities among ...
