My research interest is in the consequences of environmental change for food webs and ecosystem functions. My research addresses questions in lakes, estuarine-coastal and ocean ecosystems with a special emphasis on planktonic organisms. I conducted post-doctoral research at the University of Washington, Seattle, and at the University of California Davis, and received my PhD in Natural Sciences from the ETH in Zürich.
Konrad Karlsson, Ph.D. student, Stockholm University
Konrad’s PhD project focuses on investigating the adaptive capacity of zooplankton to environmental change. His thesis is connected to the interdisciplinary BONUS project BIO-C3, which focuses on causes, consequences and management implications of biodiversity change in the Baltic Sea. Understanding the capacity for biological adaptation is critical to predict effects of climate change. Konrad’s thesis will enhance the current knowledge on environmental tolerances and preferences of Baltic Sea zooplankton species.
Per Hedberg, Ph.D. student, Stockholm University
The goal of Per’s PhD project is to investigate how shifts in pelagic and benthic species composition can affect the flux of organic matter and nutritional quality of settling material, and feedback loops to plankton. The outcome of this research is expected to yield transformative insight on ecological interactions and the role of organic material and nutrient cycling between the open water and the sediment habitat. This project is supported by the FORMAS project: Responses of pelagic-benthic coupling to environmental change in the Baltic Sea.
Andreas Novotny, Ph.D. student, Stockholm University
In the world’s largest ecosystem, marine plankton form complex trophic interaction networks that are influenced by environmental conditions. The purpose of Andrea’s PhD study is to study zooplankton feeding preferences and hereby their function as intermediates between primary producers and fish communities, through in situ identification of dietary uptake using novel DNA barcoding. This project is connected to the VR project: Consequences of zooplankton feeding strategies on the function of marine ecosystems
Karen Lykkebo Petersen, Ph.D. student, Stockholm University
I am a PhD student in marine biology at Stockholm University. I am interested in the food web interaction between lower and higher trophic levels in the marine plankton ecosystem. Specifically, I study food web interactions between mesozooplankton and ichtyoplankton in the Baltic Sea investigating feeding behaviors using selective DNA barcoding. Further, I investigate the role of parasitism and symbiotic relations in zooplankton and its governance for the food web and ecosystem structure.
