六级Co-author Amy Zanne thinks that users probably range from climate-change researchers wanting to estimate how much carbon is stored in biomass, to foresters looking for information on different grades of timber.
合著者艾米·赞恩认为,用户可能包括希望估算生物量中储存多少碳的气候变化研究人员,以及寻找不同等级木材信息的林业工作者。

考研Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time.
他们的方法并不试图估计海洋特定地区鱼类的实际生物量(活生物物质的量),而是估计生物量随时间的变化。

考研According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) in a new fishery is reduced on average by 80% within 15 years of the start of exploitation.
根据他们在《自然》杂志上发表的最新论文,在一个新的渔场中,大型捕食者(杀死和吃掉其他动物的动物)的生物量在开始开采后的15年内平均减少了80%。

考研That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels.
这很重要,因为理论表明,当目标物种的生物量约为其原始水平的50%时,渔业可以获得的最大可持续产量。
