Environmentally derived stress can diminish the health, survival and reproduction of individuals and populations. Oxidative stress is environmentally derived stress that can be caused directly from the increased metabolism of environmental toxicants; also many chemicals, UV-radiation, metal-ions and hydrogen peroxide are oxidants themselves. Indirectly oxidative stress can be caused by the changes of chemical composition of nutrients and food webs, which can be effected by climate change and eutrophication. In my research I study how environment affects the oxidative stress status of different wild animals. One of the main topics is the temporal and spatial differences in Baltic salmon. In another study on fish I look at how an eye fluke infection affects the reactive oxygen species (ROS) production and antioxidant (AOX) status in lake salmon and arctic char and are the eye flukes themselves affected. I’ve also done studies on birds, comparing the oxidative stress status of different passerine species and studying how heavy metals affect their oxidative stress. I’ve also been involved in studies done on ringed seals, bats and polar bears among others.
