In the periods of peak zooplankton abundance, that is, in the late spring and in the summer, Haney recorded maximum daily community grazing rates, for nutrient-poor lakes and bog lakes, respectively, of 6.6 percent and 114 percent of daily phytoplankton production.
开头这个abundance,它为什么放在zooplankton之后,而且前面已经有peak作为修饰词了。
