Species Sorting of Benthic Invertebrates in a Salinity Gradient - Importance of Dispersal Limitation. [PDF]

PLoS ONE, 2016
The relative importance of environment and dispersal related processes for community assembly has attracted great interest over recent decades, but few empirical studies from the marine/estuarine realm have examined the possible effects of these two ...

Metacommunity patterns of Amazonian Odonata: the role of environmental gradients and major rivers [PDF]

PeerJ, 2019
Background We identified and classified damselfly (Zygoptera) and dragonfly (Anisoptera) metacommunities in Brazilian Amazonia, relating species distribution patterns to known biological gradients and biogeographical history.

Reserve Size And Fragmentation Alter Community Assembly, Diversity, And Dynamics [PDF]

, 2013
Researchers have disputed whether a single large habitat reserve will support more species than many small reserves. However, relatively little is known from a theoretical perspective about how reserve size affects competitive communities structured by ...

Dirichlet multinomial mixtures: generative models for microbial metagenomics [PDF]

, 2012
We introduce Dirichlet multinomial mixtures (DMM) for the probabilistic modelling of microbial metagenomics data. This data can be represented as a frequency matrix giving the number of times each taxa is observed in each sample.

Functional diversity and community assembly of river invertebrates show globally consistent responses to decreasing glacier cover [PDF]

, 2017
Global change threatens invertebrate biodiversity and its central role in numerous ecosystem functions and services. Functional trait analyses have been advocated to uncover global mechanisms behind biodiversity responses to environmental change, but the

Helminth metacommunity structure of wild rodents in a preserved area of the Atlantic Forest, Southeast Brazil

Revista Brasileira de Parasitologia Veterinária, 2018
The helminth fauna and metacommunity structure of eight sympatric sigmodontine rodents were investigated at the Serra dos Órgãos National Park, an Atlantic Forest reserve located in the State of Rio de Janeiro, southeast Brazil.

The influence of dispersal on a predator-prey system with two habitats [PDF]

, 2016
Dispersal between different habitats influences the dynamics and stability of populations considerably. Furthermore, these effects depend on the local interactions of a population with other species.

Community assembly and coexistence in communities of arbuscular mycorrhizal fungi [PDF]

, 2016
Arbuscular mycorrhizal fungi are asexual, obligately symbiotic fungi with unique morphology and genomic structure, which occupy a dual niche, that is, the soil and the host root.
