Have you ever wondered how arctic animals cope with climatic variability, extreme light-dark cycles and large seasonal fluctuations in food availability? Or which physiological adaptations aquatic birds and mammals have acquired in diving? By studying arctic animal physiology, you can find the answers as well as contribute to new science.


Our Research Group "Arctic Chronobiology and Physiology" at Dept of Arctic and Marine Biology, UiT - The Arctic University of Norway offers research-based teaching in general and comparative physiology, both at the Bachelor, Master and PhD levels, in which students are also given exclusive opportunities for field experience in the Arctic.
