| Abstract | The adverse influences of insufficient food and toxins on Daphnia carinata's body growth, reproduction and tolerance were investigated in the laboratory. Different concentrations of Scendesmus obliquus and a mixture of S. obliquus and microcystin (MC)-containing Microcystis aeruginosa PCC7820 were used to feed D. carinata. Glutathione S-transferase (GST) activity towards five chemical compounds (substrates) was measured and used as an indicator of their tolerance. Body growth rate and clutch size of D. carinata decreased with declined concentration or decreased proportion of S. obliquus in the diet. GST activity decreased with ageing in D. carinata. However, GST activity to several chemical compounds increased when food quantity or food quality decreased. Adult D. carinata had a lower GST activity towards p-nitrophenenzyl chloride (PNBC) than juveniles and exhibited a sharp decline (P < 0.001) in GST activity towards PNBC as the animals aged. It is suggested that the age-specific decrease in GST activity is a possible mechanism for the high morality of adult D. carinata in the summer of eutrophic lakes. |
