| 摘 要： | 对南极沿海伯尔顿盐湖浮游桡足类双剌镰状水蚤的耗氧量进行六个月的连续测定,结果表明,动物在越冬过程中氧代谢呈下降趋势,其耗氧量从8月份的0.2775(μl·mg~(-1)wet·h~(-1))到翌年1月份降为0.0467(μl·mg~(-1)wet·h~(-1));其中8—12月耗氧量变化较为平缓,月平均下降率为14.62％;12—1月耗氧量变化较大,下降率为66.93％。动物的耗氧量与盐湖环境的季节变化和动物自身的一些生理变化有密切的关系,在12月份以前动物耗氧量变化可能主要与湖中浮游植物和溶解氧的减少有关,而12月份以后动物的迅速衰老则可能成为动物耗氧量急剧下降的重要因素。

| 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. |
