Dimensions Project

The aim of the project, a large, NSF-funded effort, is to figure out how communities of arthropods come together over time – is there a predictable sequence of arrival (both in the short- and long term) and does this differ between trophic levels? Is there a point at which biodiversity reaches a stable state and prior to this, are communities more vulnerable to invasion? The particular importance of the work is that it will provide understanding of how communities come together, and the role of ecology (migrating into a community, trophic level) and evolution (adaptation and speciation) in determining the composition of species in a community. This in turn will provide information on sensitivity to invasion and probability of speciation and extinction.
