Johan Wikner serves as Professor in the Department of Ecology, Environment and Geoscience at Umeå University, Sweden. His research focuses on marine microbial ecology, specifically investigating controls on bacterial and archaeal respiration and growth in oceanic systems with critical implications for global carbon and oxygen cycles.
His primary research interests encompass:
- Marine Microbial Ecology
- Ocean Carbon Cycle dynamics
- Bacterial and Archaeal Respiration mechanisms
- Oxygen Dynamics in marine environments
- Climate Change impacts on Arctic and Baltic Seas
- Eutrophication processes
- Environmental Monitoring methodologies
Wikner's recent publications (2017-2024) demonstrate consistent focus on prokaryotic respiration in polar and brackish waters, development of precise oxygen measurement techniques using sensor technology, and climate change effects on microbial carbon processing. His work integrates long-term monitoring data, mesocosm experiments, and field studies across spatial scales to address fundamental questions about oceanic carbon cycling.
As head of the Johan Wikner Lab and member of Umeå Extracellular Vesicle Network and EcoChange research groups, he directs projects examining Arctic prokaryote adaptation, pathogenic fungi roles in carbon cycles, and Baltic Sea oxygen dynamics. Funded by Kempestiftelserna and EcoChange, his research provides scientific basis for environmental policy related to UN Sustainable Development Goal 14 (Life below water) and Swedish environmental objectives.
