In the periods of peak zooplankton abundance,that is,in the late spring and in the summer, Haney recorded maximum daily com-munity grazing rates,for nutrient-poor lakes and bog lakes,respectively,of 6.6 percent and 114 percent of daily phytoplankton production.
在这个时期浮游动物数量的高峰期,即在春末和夏季,Haney记录了最高的每日群落食草速率,对于贫养湖和沼泽湖而言,分别为,6.6%和114%每日浮游植物繁殖量的。
Studies by Hargrave and Geen estimated natural community grazing rates by measuring feeding rates of individual zooplankton species in the laboratory and then computing community grazing rates for field conditions using the known population density of grazers.
研究由Hargrave和Geen所进行的,估计了自然群落的食草速率通过测量捕食速率浮游动物个体的在实验室内,然后通过计算群落的食草速率实地状况下的利用已知的食草动物种群密度。
