The physiology group studies the physiology and ecophysiology of various groups of organisms, including birds, fish, insects, and woody plants, at levels ranging from individual cells (insect nerves), through isolated tissues and organs (tree leaves and buds), to whole organisms (insects and birds). There are five subgroups with emphases in bird energetics, fish physiology, insect neurophysiology, insect stress physiology, and plant stress physiology.
The marine biological activities comprise research fields such as ecology, physiology, bio-systematic, genetics of populations and dynamics in marine ecosystems. The Trondheim fjord system serves as a model for many marine biological studies. Aquaculture research aims at a better understanding and exploitation of marine biological resources. A significant part of the research is characterised by interdisciplinary research in the cross-over between marine biology, aquaculture and technological development. Research projects focus on juvenile aquaculture technology, larval nutrition, quality, and developmental biology of species like Atlantic cod, Atlantic halibut and Atlantic salmon, as well as blue mussels. A strategic focus is put on improved area resource management for aquaculture by integrated aquaculture and on exploitation of marine resources for fish feed such as zooplankton. Additionally the group addresses eco-toxicological problems in the sea.
Trondheim biological station (TBS) is the centre for marine biological research at NTNU, while aquaculture research activities are centered at Sealab . Research activities include laboratory studies as well as extensive field work. The research facilities offer good office and laboratory facilities, a research vessel, and are located on the shore of the Trondheim fjord. .
