1. Cytochrome P-450 in Drosophila melanogaster : activity, genetic variation and regulation
Abstract : The cytochrome P-450 enzyme system in the fruit fly, Drosophila melanogaster, was shown to be inducible, to consist of several isozymes and to have the capacity to metabolize a variety of substrates, thus resembling the corresponding mammalian system. These similarities strengthens the value of Drosophila test systems for the detection of indirect carcinogens and mutagens. READ MORE

2. Hitting the mark : studies of alterations in behaviour and fertility in ethinyl estradiol-exposed zebrafish and search related biomarkers
Abstract : In this thesis, we have analysed the effects of EE2 on non-reproductive behaviours and fertility. We have showed that two doses of EE2 in male adult short-term exposures evokes opposite behaviours in the novel tank test. READ MORE

3. Selective serotonin re-uptake inhibitors in the environment : Effects of citalopram on fish behaviour
Abstract : Selective serotonin re-uptake inhibitors (SSRIs) are a class of anxiolytic and anti-depressant drugs. SSRIs act on the evolutionarily ancient serotonergic system which is virtually identical throughout the vertebrate phylum. READ MORE

4. Genetic Aspects of Environmental Disturbances in Marine Ecosystems : Studies of the Blue Mussel in the Baltic Sea
Abstract : Anthropogenic environmental changes can serve as drivers for evolutionary responses in wild populations. To predict the long-term impact of anthropogenic changes on populations, it is crucial to understand the genetic effects caused by these disturbances. READ MORE

5. Endocrine disruption in fish : Effects of 17α-ethinylestradiol exposure on non-reproductive behavior, fertility and brain and testis transcriptome
Abstract : Aquatic environments are the end recipient for most anthropogenic chemical pollutants. One common chemical pollutant found in the aquatic environment is 17α-ethinylestradiol (EE2), a synthetic estrogen used in contraceptive pills. READ MORE
