Dr. Thomas Bøhn holds a Doctorate in Fresh Water Ecology from the University of Tromsø (2002).
Research interests
My research interests are focused on the impact of modern biotechnologies, especially genetically modified organisms (GMOs) on experimental model systems and on real food-webs. I the laboratory I study the food quality and ecotoxicity of GM plants (e.g. maize and soy) in a feeding model using the waterflea Daphnia magna, also in combination with chemical stressors (herbicides used on GM plants, pesticides and other chemical pollutants). Effects and consequences are evaluated at the level of the genotype/ molecular biology (e.g. changes in gene expression, potential uptake, distribution and expression of transgenic DNA and protein), at the phenotype (mortality, growth, fecundity, behaviour), and on a population level using structured population models (population growth rate, sensitivity, dynamics etc.). In the field I work with impacts of modern biotechnologies on biodiversity and food-webs, both in terrestrial and aquatic systems. I also have great interest in evolution, biodiversity, ecological interactions and invasion biology.
