Perhaps the fact many of these first studies considered only algae of a size that could be collected in a net (net phytoplankton), a practice that overlooked the smaller phytoplankton (nannoplankton) that we now know grazers are most likely to feed on , led to a de-emphasis of the role of grazers in subsequent research.
可能這樣一個事實，那就是很多這樣的最初的研究只是考慮了那些能夠用網(wǎng)撈起來的大小的水藻，這樣一個忽視了更小的浮游生物(而這些浮游生物我們現(xiàn)在知道是捕食者主要的食物)的做法，導(dǎo)致了在接下來的研究中對于捕食者的作用的貶低。
