Abstract
Survival of transparent and pigmented Daphnia from alpine as well as arctic habitats, exposed to solar radiation with total or reduced UV-B, was measured. In the alpine pond, survivorship and reproduction of transparent juvenile as well as adult Daphnia were significantly reduced due to UV-B. Transparent adult arctic Daphnia also showed significant reduction in survivorship when exposed to total, when compared with controlled solar radiation. In contrast, heavily melanized adult arctic Daphnia showed no increase in mortality when exposed to natural solar radiation. There appeared to be differences both in tolerance and behavior in the two arctic forms when exposed to solar radiation.
