采用多元回归方法，将上层海洋浮游动物的代谢率（氧摄取、氨排泄、磷酸盐排泄）表示为体重（干、钙、镍、磷）和栖息地温度的函数。用于本分析的浮游动物数据来自不同纬度（栖息地温度范围：-14度）的系统发育混合群（56-143种，代表7-8门，体重范围：6个数量级）。摄氏到三十度。C)。结果表明，84-96%的代谢率变化是由体重和栖息地温度引起的。在各体重单位中，C和N单位对3种代谢率的相关性最好。氧吸收、氨排泄和磷酸盐排泄在体质量效应上相似，但在温度效应上不同。以C或N体-质量体-质量为单位，计算得到的Q10值分别为氧气摄取1.82-1.89、氨排泄1.91-1.93和磷酸盐排泄1.55。体重和生境温度对代谢商（O:N, N:P, O:P）的影响不显著。目前关于臭氧吸收率与体重的结果与Hemmingsen报道的一般变温动物和Ivleva报道的甲壳类动物在相当温度（20度）下的结果没有显著差异。C)。通过对混合类群和选择类群间生境温度效应的评价，说明了体质测量对有意义的比较的重要性。考虑到体重和温度对浮游动物代谢率的主导作用，估算了海洋中净浮游动物群落代谢率的纬度梯度，强调了群落代谢率与净浮游动物常备存量之间的不平行性。
The metabolic rates (O2 uptake, ammonia excretion, phosphate excretion) of epipelagic marine zooplankton are expressed as a function of body mass (dry, Ca, Ni and P weights) and habitat temperature, using the multiple-regression method. Zooplankton data used for this analysis are from phylogenetically mixed groups (56-143 spp., representing 7-8 phyla, body mass range: 6 orders of magnitude) from various latitudes (habitat temperature range: -14.degree. C to 30.degree. C). The results revealed that 84-96% of variation in metabolic rates is due to body mass and habitat temperature. Among the various body-mass units, the best correlation was provided by C and N units for all 3 metabolic rates. O uptake, ammonia excretion and phosphate excretion are all similar in terms of body-mass effect, but differ in terms of temperature effect. With C or N body-mass body-mass units, calculated Q10 values are 1.82-1.89 for O2 uptake, 1.91-1.93 for ammonia excretion and 1.55 for phosphate excretion. The effects of body mass and habitat temperature on the metabolic quotients (O:N, N:P, O:P) are insignificant. The presents results for O2-uptake rate vs. body mass do not differ significantly from those reported for general poikilotherms by Hemmingsen and for crustaceans by Ivleva at a comparable temperature (20.degree. C). The importance of a body-mass measure for meaningful comparison is suggested by the evaluation of the habitat-temperature effect between mixed taxonomic groups and selected ones. Considering the dominant effects of body mass and temperature on zooplankton metabolic rates, the latitudinal gradient of community metabolic rate for net zooplankton in the ocean is estimated, emphasizing the nonparallelism between community metabolic rates and the standing stock of net zooplankton.
