Martin Österling

Martin Österling is a Full Professor in Biology at Karlstad University, specializing in freshwater ecology, conservation biology, and the interplay between aquatic species and their environments. His research focuses on understanding ecosystem dynamics, particularly involving freshwater mussels (e.g., Margaritifera margaritifera), their interactions with host fish such as brown trout (Salmo trutta), and the impacts of environmental changes like climate shifts and habitat fragmentation. He has contributed to studies on mussel biology, fish behavior, and the effects of anthropogenic pressures such as dams and pollution.

Key research themes include: 1) Conservation biology of endangered species through captive breeding and habitat restoration, 2) Effects of temperature and predation on fish development, 3) Mussel-parasite-host dynamics and their ecosystem roles, and 4) River management strategies for migratory fish. His work bridges ecology, genetics, and applied conservation, often involving field experiments and multi-institutional collaborations.

Recent articles highlight studies on dam passage challenges for Atlantic salmon, cold tolerance in mussels, and the behavioral adaptations of fish under changing environmental conditions. He has also explored the role of mussels as indicators for water quality and ecosystem health. Collaborators include researchers from institutions across Europe, emphasizing transnational conservation efforts.
