Habitat heterogeneity drives bird species richness, nestedness and habitat selection by individual species in fluvial wetlands of the Paraná River, Argentina
(Wiley Blackwell Publishing, Inc, 2016-11)
We assessed the relationship between habitat heterogeneity and bird species richness and composition within wetlands of the floodplain of the Middle Paraná River, Argentina. Given the high habitat heterogeneity in these ...
Species Turnover through Time: Colonization and Extinction Dynamics across Metacommunities
(Univ Chicago Press, 2016-06-01)
Island biogeography and metacommunity theory often use equilibrium assumptions to predict local diversity, yet nonequilibrium dynamics are common in nature. In nonequilibrium communities, local diversity fluctuates through ...
Polyembryony increases embryo and seedling mortality but also enhances seed individual survival in Handroanthus species (Bignoniaceae)
(Elsevier Gmbh, Urban & Fischer Verlag, 2012-01-01)
Polyembryony seems to be advantageous to mother plants in detriment of their siblings which face competition since the beginning of seed development. This competition may limit the turnover of embryos into seedlings and ...

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 ...
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 ...
Alien plants and flower visitors disrupt the seasonal dynamics of mutualistic networks
(Wiley-Blackwell, 2020-01-13)
Alien species can drastically disrupt ecological processes such as those involving plant-pollinator interactions, performing central roles that may affect the structure of native pollination networks. However, most studies ...
