食物网

20世纪60年代,科学家们提出,食物网顶端的捕食者对其他物种（包括它们没有直接攻击的物种）的数量有着惊人的控制力。

In the 1960s , scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species --- including species they did not directly attack ．

通过这些模型,科学家们发现了一些在食物网中运作的关键原理。

With such models , scientists have found out some key principles operating in food webs ．

例如,大多数食物网都包括许多薄弱环节,而不是所有环节都是牢固的。

Most food webs , for instance , consist of many weak links rather than a few strong ones ．

食物网可能主要由许多较弱的食物链构成，因为这种构成方式在长期内更为稳定。

Food webs may be dominated by many weak links because that arrangement is more stable over the long term ．

为了找到答案，科学家们建立了食物网的数学模型，记录下食物链的前后者以及前者的食用量。

To find an answer , scientists have built mathematical models of food webs , noting who eats whom and how much each one eats ．

数学模型也揭示了食物网可能是不稳定的,食物网中顶级捕食者的微小变化会对整个生态系统产生巨大影响。

Mathematical models have also revealed that food webs may be unstable , where small changes of top predators can lead to big effects throughout entire ecosystems ．

所谓鱼类生物操纵（biomanipulation），即通过改变处于食物网、链顶端鱼类的组成，影响河道营养物质水平，达到改善水质的目的。

The biomanipulation of fish was to effect nutritious substance in rivers to improve water quality by changing the composition of fish which lied in the tope of food web .

这样，错综复杂的食物网就大大简化了。

The complexity of the food web is thus greatly simplified .
