食物链等级体系中的高等级物种平均捕获率(而捕获正在并将持续进行)处于持续上升态势之中——按照所谓食物链等级理论，这应当意味着海洋生态系统的健康平衡发生了变化。
The average trophic level of what is being caught is rising — and this in principle should indicate improving ecosystem health.
如果将关注食物链顶端和底端的方法同时应用到全球性数据上，那么，科学家们得出的结论是，过去10年的工业捕渔更偏向捕食低食物链鱼类，而对高食物链等级的鱼类而言，它们的食物总量减少了将近一半，倘若按照食物链理论的逻辑，现存高食物链等级的鱼类总数是增加了而不是减少了，因此，不能够简单地认为，工业“捕渔”导致鱼类总体的数量减少。
Applying both methods to worldwide data, the scientists say industrial fishing over the past decades has not simply worked its way downwards from the top of the food chain -- it has gone upwards, too.
一个身体产生“生命之热”的数量直接决定了它在“存在之链”中的位置——一个依据个体的完善程度来安排的等级序列。
The amount of "vital heat" produced by a specific body was viewed as a direct index of its place in the "great chain of being", a hierarchical order of rank according to degrees of perfection.
自1990年代起，科学家和区域性管理机构就已经开始了数据收集工作，通过对“食物链等级”上不同种群间的生态平衡变化进行定量研究。
Since the late 1990s, scientists and regional management organisations have used catch data to measure changes in the balance of species across so-called "trophic levels."
根链和贵贱等级症影响着当下人的生存观念和思维模式。

在上一代所有高等级的同类组中，具有相同集合令牌的所有上行链路被集合在一起。
In the parent and all higher-level peer groups, all uplinks with the same aggregation token are aggregated .
对于大学毕业生而言，的确很难从食物链最高等级转换到职场的新人。
It is sometimes hard for recent college graduates to transition from top-of-the-food-chain seniors to professional "freshmen."
