Abstract:

The oxygen consumption of Drepanopus bispinosus and its relationship to the environmental parameters were determined from Burton Lake,a meromictic saline lake in Antarctica. The resuls direct that animal's respiration is decreasing when they overwinter. It was 0. 2775(μl·mg-1 wet·h-1)in August and droped down to 0. 1412 when it was December. This could relate with seasonal change of the lake conditions, mostly with the decreasing of dis solved oxygen in the eater. Further,the respiration rate decline sharpiy from December to January in 66. 93%. This could be lerated with animal's senescence and its' failing physiological function. The Q10 of the copepod female adults was 1. 90 in August and 3. 13 in January with natural conditions.
