研究了不同大小级（100-200、200-500和500-1000 μ m）海洋浮游动物的呼吸（R）和电子传递系统（ETS）活性，以确定影响这两个参数之间关系的可变性的因素。WETS比率在文献中观察到的值范围内变化。在较小的尺寸级分中，变异性更明显。我们发现这个比例和初级生产平行变化的发展过程中，在加那利群岛沃茨的冬末水华。观察到较高的比率与较高的初级生产值相吻合。当汇集来自不同海洋环境的数据时，我们发现这些比率与温度呈负相关。WETS比值似乎反映了浮游动物代谢活动的范围。使用一个如何通过系统，我们观察到短期的呼吸速率和ETS活动有关的活动水平的生物体。这表明，两种测量之间的关系的变异性可能是由于使用经典平衡法评估呼吸速率的不足和在Vmax下测量酶的问题。
Respiration (R) and electron transport system (ETS) activity were studied in marine zooplankton of different size classes (100-200, 200-500 and 500-1000 mu m) in order to determine the factors affecting the variability of the relationship between the two parameters. The WETS ratio varied within the range of values observed in the literature. The variability was more pronounced in the smaller size fraction. We found this ratio and primary production to vary in parallel during the development of the late winter bloom in the Canary Island waters. Higher ratios were observed to coincide with higher values of primary production. When the data from different oceanic environments were pooled, we found the ratios to be inversely related to temperature. The WETS ratio seemed to reflect the scope of metabolic activity in the zooplankton. Using a how-through system, we observed short-term respiration rates and ETS activities to be related to the activity level of the organisms. This suggests that variability in the relationship between both measurements could be due to the inadequacy of assessing respiration rates using the classical balance method and the problem of measuring enzymes at V-max.
