Dr. Johan Wikner

Biography

Johan Wikner's research focuses on understanding the controls of respiration and growth in Bacteria and Archaea, particularly in the context of their relevance to carbon and oxygen cycles in the ocean. His academic contributions include exploring the ecological roles of prokaryotes in marine microbial ecology, particularly related to organic matter decomposition and associated oxygen consumption. He has specific research interests in the impacts of carbon and nutrient discharge on prokaryotic activity in coastal waters, as well as the influences of shrinking ice cover in the Arctic Ocean on carbon transformations. A notable aspect of his research involves the development of precise methods for estimating oxygen consumption using sensor technology and Peltier-elements, which is crucial for understanding the environmental factors affecting bacterial dynamics across large spatial and temporal scales. As part of his work, he contributes to the Swedish Institute of the Marine Environment, analyzing the status of marine environments to inform national environmental goals related to eutrophication and sustainable water management.
