Population Effects Signal Ecologists Isolate S Order Nature

en In order to understand the nature of the ecologist's investigation,we may think of the density-dependent effects on growth parameters as the “signal” ecologists are trying to isolate and interpret,one that tends to make the population increase from relatively low values or decrease from relatively high ones, while the density-independent effects act to produce “noise” in the population dynamics.

解释: 句子不仅很长,而且有两个地方看上去不舒服:第一,think of...不是很常见,其实think of这个词组就等于consider、imagine,加上后面的as,就是把……认为是……的意思。第二个不习惯的地方是“signal”后面的大段修饰语,不但长度很长,而且在signal后面还省略了一个that ,正常应该是the “signal” that ecologists are trying to isolate and interpret。与以前见过对that的省略不同的是,这次that在句中不是句子的宾语,而是不定式动词的宾语。
