Research interests

A primary goal of ecology is to measure, understand, and predict patterns of biodiversity, which in turn requires investigation of the factors that structure ecological communities. These include not only environmental features, which shape species composition patterns, but also the connectivity of communities by dispersal, which influence species structure. These considerations have given rise to the concept of metacommunity, defined as a set of ecological communities at different sites, potentially but not necessarily linked by dispersal. The term has been applied in studies of the mechanisms underlying the dispersal of organisms, including within the context of community structure. Therefore varying mathematical methods might be used.

However, studies on the mechanisms structuring metacommunities have largely ignored freshwater nematodes. Therefore and because of the ecological importance of this group they are very interesting organism for analysis of distributional pattern in the light of metacommunity theory.

In this context we currently evaluate data on nematode abundances from different aquatic habitats. We hope to determine factors that are important for nematode community structures.
