I study aquatic ecology and biogeochemistry in northern lakes and brackish water coastal ecosystems, focusing on benthic processes. I mainly focus on the lower trophic levels in aquatic food webs, i.e. algae and bacteria, but also their relative contribution to higher trophic levels. More specifically, I study how biotic and abiotic factors influence the metabolism (primary production and respiration), biomass development and species composition of algae and bacteria in various aquatic ecosystems. Within this context, I also investigate the structural difference between benthic and pelagic habitats, and how environmental factors control the distribution of metabolic processes between these habitats. On a larger scale, I am interested in how aquatic ecosystems are affected by input of terrestrial organic matter, the role of aquatic environments in the global carbon cycle, and also winter (under ice) processes.
The Limnology and Oceanography Research Exchange (LOREX) is a formal training and professional development program in international research collaboration in the aquatic sciences offered by the Association for the Sciences of Limnology and Oceanography (ASLO).
The participants came to our station to do field work related to their research. They’ve shared their research as well as cultural experience they gained through this exchange programme in blog posts, videos, pictures, on our social media, in public talks, science seminars, and through their contribution in our podcast.
The Limnology and Oceanography Exchange (LOREX) programme encourages students from the U.S. to gain international experience through collaborations and projects with partners abroad. This year, CIRC will host PhD students participating in the project.
My research aims to better understand how primary production in lakes is affected by climate change. I am looking into both direct and indirect effects of climate change on pelagic and benthic algae production, and what potential implications these have on energy- and nutrient transfer to higher consumers in lakes.
