Arctic carnivore health
Arctic regions are one of the most affected by climate change, first evidences being noted already in the 1980s. However information on wildlife population health is still limited and requires continuous monitoring.

|Understanding wildlife health and disturbed homeostasis|
|Understanding the environmental context|
The arctic fox (Vulpes lagopus) is the only native terrestrial mammal in Iceland. Because of the relatively low biodiversity within Arctic and the involvement of the species in both marine and terrestrial ecosystems, the arctic fox population could serve as sentinel for overall ecosystem health of Iceland. Despite the long-term monitoring of the Icelandic fox population, there is almost no information on the health status of this species. In collaboration with colleagues from the Icelandic Institute of Natural History, we aim to monitor various environmental pollutants, parasites and pathogens which might threaten this and other species, including humans.
Besides providing baseline epidemiological information, we are interested on the physiological consequences (immunology, stress/allostatic load) of the sublethal exposure to environmental pollutants and the potential adaptation of the species to this geologically active environment. Recently we also obtained samples from the long-term project on polar bears (Ursus maritimus) from Svalbard, Norway, where we will measure adaptive and innate immune markers in order to better understand the effect of climate change and anthropogenic activities on Arctic biota.
