The internal structure of metacommunities [PDF]
Oikos, 2020 Current analyses of metacommunity data largely focus on global attributes across the entire metacommunity, such as mean alpha, beta, and gamma diversity, as well as the partitioning of compositional variation into single estimates of contributions of space and environmental effects and, more recently, possible contributions of species interactions ...

A Metacommunity Approach to Improve Biological Assessments in Highly Dynamic Freshwater Ecosystems
BioScience, 2020 Rapid shifts in biotic communities due to environmental variability challenge the detection of anthropogenic impacts by current biomonitoring programs.

Ecosphere, 2021 According to metacommunity theory and previous experiments, inter‐patch dispersal rates may alter species diversity at local to regional scales. In this study, we tested the predictions of metacommunity theory regarding the effect of dispersal rates on ...

A global database for metacommunity ecology, integrating species, traits, environment and space
Scientific Data, 2020 The use of functional information in the form of species traits plays an important role in explaining biodiversity patterns and responses to environmental changes. Although relationships between species composition, their traits, and the environment have

Ecology Letters, 2021 Dispersal and dormancy are two common strategies allowing for species persistence and the maintenance of biodiversity in variable environments. However, theory and empirical tests of spatial diversity patterns tend to examine either mechanism in ...

Evolution in metacommunities [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2011 A metacommunity can be defined as a set of communities that are linked by migration, and extinction and recolonization. In metacommunities, evolution can occur not only by processes that occur within communities such as drift and individual selection, but also by among-community processes, such as divergent selection owing to random ...

Recent advances in metacommunities and meta-ecosystem theories [version 1; referees: 2 approved]
F1000Research, 2017 Metacommunity theory has provided many insights into the general problem of local versus regional control of species diversity and relative abundance. The metacommunity framework has been extended from competitive interactions to whole food webs that can

Biodiversity on island chains: neutral model simulations
, 2010 A neutral ecology model is simulated on an island chain, in which neighbouring islands can exchange individuals but only the first island is able to receive immigrants from a metacommunity.

The response of neotropical dragonflies (Insecta: Odonata) to local and regional abiotic factors in small streams of the Amazon [PDF]
, 2019 Since the relative role of local and regional abiotic factors on the Odonata diversity in rainforest streams is still poorly understood, we evaluated the effects of these factors on adult Odonata (Insecta) from preserved and altered streams in the ...
