1. 1.通过对南极和温带陆栖阿卡里的标准代谢（以重量比耗氧量衡量）的比较分析表明，极地隐气门目和中气门目的代谢比正常环境温度范围高2-4倍。2. 2.代谢-温度曲线的极地和温带形式是相似的两组螨。3. 3.南极螨的Q10值从1.28到3.36不等，这对应于温带物种范围的较低部分。4. 4.本文对低温适应变温动物代谢水平的提高进行了综述和讨论。5. 5.目前的证据表明，南极陆栖螨通过提高标准代谢来适应低温环境。
1. 1. Comparative analyses of standard metabolism, as measured by weight specific oxygen consumption, for Antarctic and temperate terrestrial Acari show that polar forms of the Cryptostigmata and Mesostigmata exhibit an elevation of metabolism of 2–4 times over their normal environmental temperature range. 2. 2. Metabolism-temperature curves of polar and temperate forms are similar for both groups of mites. 3. 3. Q10 values for Antarctic mites vary from 1.28 to 3.36, which correspond to the lower portion of the range for temperate species. 4. 4. The elevation of metabolism as a feature of cold adapted poikilotherms is reviewed and discussed. 5. 5. Present evidence suggests that Antarctic terrestrial mites adapt to their low temperature environment by an elevation of standard metabolism.
