The role of dispersal networks in structuring biotic communities: A tale of streams and metacommunity theory
Identifying the processes and mechanisms that govern communities of organisms is the main goal of community ecology. Locally operating mechanisms such as environmental filtering, in which the environment determines what species are found in a given location, as well as regional processes such as …

Drivers of plant and arthropod diversity and community structure in a grassland ecosystem
… are known to influence species coexistence and community organization, although the relative importance of these forces is debated. While niche-based models emphasize the effect of local processes on community structure, regional species pools and dispersal abilities of organisms are also …

Investigating mechanisms maintaining plant species diversity in fire prone Mediterranean-type vegetation using spatially-explicit simulation models
… systems like those in the Mediterranean Basin and South-Western Australia are global hot spots for plant species diversity. To ensure management programs act to maintain these highly diverse plant communities, it is necessary to get a profound understanding of the crucial mechanisms of …

The population and community ecology of small freshwater ponds: Assigning process to pattern
… patterns of spatial structuring for populations and communities inhabiting natural and, more recently, human-created ecosystems. Empirical and theoretical advancements have highlighted the importance of considering the effects of both historical (i.e., colonization history and priority effects) …
