背景情况:
- 净生态系统代谢 (NEM) 对于评估水产养殖健康和预测长江河口 (CRE) 缺氧风险至关重要.
- 由季风和潮驱动的CRE复杂的水文制度掩盖了高频风和潮变化对NEM动态的影响.
研究的目的:
- 为了研究风和潮变化的影响NEM动态在CRE的鱼水产养殖场.
- 用高频现场测量和DO质量平衡模型阐明NEM波动背后的驱动机制.
主要方法:
- 在2022年9月至10月期间,部署一个高分辨率的现场分析仪,以1分钟的间隔测量溶解氧 (DO).
- 应用一维DO质量平衡模型来量化NEM和分析驱动力.
主要成果:

Osmoregulation in Fishes
50.5K
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Primary Production
24.0K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.
