Diurnal patterns of antioxidant activity in alpine and arctic Daphnia under in situ UV-radiation

Autor: Jan Borgeraas, Dag O. Hessen

Publikováno v: Archiv für Hydrobiologie. 156:83-95

Diurnal variation in the activity of the antioxidant enzymes catalase (CAT), glutathione transferase (GST) and superoxide dismutase (SOD) were studied in one arctic Daphnia tenebrosa and two alpine D. longispina populations. Both the alpine ponds wer

To assess their role in photoprotection in the crustacean zooplankton Daphnia spp., activities of the antioxidants catalase (CAT), superoxide dismutase (SOD), glutathione transferase (GST) and content of carotenoids (CAR) were studied in 4 Daphniaspe

Isoenzymes of glutathione transferase (GST) were partially purified from the earthworm species Eisenia andrei and E. veneta using affinity chromatography followed by ion exchange chromatography and reversed-phase HPLC. In E. veneta, five activity pea

UV-B tolerance and susceptibility of high Arctic morphotypes of the Daphnia pulexl D. tenebrosa complex were assessed by in situ experiments at Ny-Alesund, Svalbard (79°N). Animals from local ponds were exposed to ambient light plus additional UV-B
