"The key point is that the Gulf of Eilat is an oligotrophic sea, a sea that does not have nitrogen at all," Loya explained. 洛亚解释道：“关键是埃拉特海湾是一片营养贫乏、完全不含氮的海域。”
The extremes of the ranges represent relative oligotrophic and eutrophic conditions. 范围的极限代表相对寡营养和富营养的条件。
Nitrates and phosphates are present in oligotrophic systems in low concentrations.They set the environmental carrying capacity. 寡营养体系中硝酸盐和磷酸盐浓度低,这两种物质决定水的纳污能力。
The results showed that C. edule declined in the oligotrophic controls, while macroalgae was dominant in the enriched tanks. 研究结果显示，控制组的食用松藻因低营养盐而于实验期间即死亡消失，营养盐添加组的食用松藻则大量繁生。
We also investigate the effects of phosphorus input conditions, corresponding to oligotrophic, mesotrophic and eutrophic systems on system dynamics. 我们还探讨磷输入条件下，相应的贫营养，中营养和富营养化系统系统动力学。
The results show that the eastern sea area of Xiamen is oligotrophic,while the western sea area is at the stage of phosphorus-limited potent... 与厦门西海域相近，中国近海主要河口、海湾总体上处于磷限制或磷中等限制潜在性富营养水平。
