UV‐induced pigmentation in subarctic Daphnia
The distribution of the planktonic crustacean Daphnia and the occurrence of ultraviolet (UV)‐protective melanin pigmentation in its body wall were studied in relation to the UV transparency in subarctic ponds and lakes in Finnish Lapland. In shallow ponds, Daphnia only occurred in those with suffici...
