EcoCatch - Stream Ecology and Catchment Biogeochemistry - is the new group name of the former working group BERG. Since Jakob Schelker took over the lead of the group from Tom Battin two years ago, the focus has shifted towards investigating the importance of soil-stream connectivity and in-stream processing for landscape biogeochemistry. Main research topics of EcoCatch are biogeochemistry, stream ecology, microbial ecology and biodiversity of streams, cycling of carbon, nutrients and metals.
