We are focusing on three integrated researchareas, namely the biology (autecology) of marine invertebrates, the ecology of coastal habitats and the biodiversity of coastal ecosystems. We are using an approach looking from small aspects to increasingly larger scales. Understanding the autecology of selected species helps us to understand ecological relationships in their habitats. Revealing important ecological process in particular habitats allows us to unravel important processes influencing local diversity in marine ecosystems. Main funding for these projects is received through FONDECYT, SHOA and other national and international funding sources.
