Sector of Ecological Physiology and Toxicology
The main research trends – functioning of aquatic animals under conditions of anthropogenic impact, regularities and mechanisms of adaptation in ontogenesis. The effect of pollutants on aquatic animals of various phylogenetic levels, their functional systems and parameters is studied evaluating their sensitivity at different stages of development. Physiological biomarkers of separate pollutants mostly spread in Lithuanian waters are searched. Participating in projects on salmonid populations restoration in Lithuanian inland waters the research of the physiological status of wild and hatchery-reared salmonid fish from the early ontogenesis is performed.
Research on anthropogenic effects on physiological and behavioural responses of aquatic animals, regularities and mechanisms of those responses started at the Laboratory of Ecology and Physiology of Hydrobionts in 1968. In 1970, the Research Group for Investigations into Aquatic Animals Behaviour was established, later the Sector of Ecological Physiology and Ethology, presently the Sector of Ecological Physiology and Toxicology. Up to 1985, mostly hydrobiont electroreception problems, after-effects of electric fields on aquatic organisms of different phylogenetic level were investigated, effective for electrofishing, environmental friendly parameters of the electric current were analised. Ecotoxicological problems were started to study in 1988.
