Capacity of fish to respond environmental stressors. The aim of these studies is to evaluate how fish can respond to different environmental stressors like climate warming, hypoxia, environmental toxins, OA and their interactions. Studies are done from molecular level responses to functional responses evaluating also the transgenerational and evolutionary potential of fish to respond stressors. For the studies we are using e.g. threespined sticklebacks from nuclear power plant areas or hypoxic lakes analysing how decades of warming/hypoxia has influenced their capacity to respond environmental challenges. We are also evaluating thermal tolerances and cardiac capacities of migrating salmonids and performing studies in laboratory environment with zebrafish.
