1·This paper reviewed some, recent progress in the assessment of water eutrophication, including model designing, application of trophic and biological indexes.
本文综述了近年来水体富营养化评价的一些进展，其中包括模型制作、营养和生物指数的应用。
2·The ecosystem appears to be a young weak one caused by overfishing, with small and low-valued fishes dominated and low ecotrophic efficiency for trophic level I.
系统受过度捕捞渔业影响很大，并存在营养级I利用效率低和渔业资源小型化、低值化等不稳定的幼态特征。
3·Stable isotopic characteristics of fatty acid and amino acid can reveal trophic structures, matter and energy flow processes of Marine food webs in detail.
通过脂肪酸、氨基酸等分子的稳定同位素特征，可以更细致更准确地了解食物网的营养结构、物质和能量的传递过程。
4·Up-regulation of jejunal IGF-1 and IGF-IR expression during refeeding suggests a role for the IGF action pathway in gut trophic responses to enteral nutrients.
再喂养时空肠IGF-1和IGF-IR表达的向上调节表明，IGF作用途径在对肠内营养物产生肠道营养反应的过程中起作用。
5·Hunting food behavior of natural enemy depends on information from various trophic levels, especially chemical information.
天敌搜寻食物的行为依赖于来自不同营养阶层上的信息，化学信息起重要作用。
