- 在NRLP干预之前了解河流的生态状况对于有效的环境管理至关重要.
研究的目的:
- 探索沙尔达河岩层藻类的生物监测潜力.
- 用藻和物理化学参数评估沙尔达河的生态状况.
- 评估各种藻指数对于该地区河流生物监测的适用性.
主要方法:

- 使用等级聚合集群分析 (HACA) 和主要组件分析 (PCA) 的物理化学数据分析.
- 用水质指数 (WQI) 和多种藻指数 (TDI,IPS,IDG,IDSE) 进行生态评估.
主要成果:
- 确定了两个不同的地点组:未受污染的库马昂喜马拉雅山 (KH) 和受污染的泰拉伊平原 (TP).
- 亚原子多样性从KH减少到TP,与水质变量有显著的相关性.
- 具体污染敏感度指数 (IPS) 在地点分类和生态状况确定方面显示出比WQI更好的分辨率.
结论:
- 藻是沙尔达河的有价值的生物监测器,反映了受水体形学和人类活动影响的生态状况.

The deep ocean and its underlying sediments represent vast, largely unexplored microbial habitats that extend far beyond the sunlit photic zone. The photic (euphotic) zone typically spans the upper ~100–200 meters of pelagic waters in the open ocean, but its depth varies geographically and seasonally, where sufficient light supports photosynthetic life. Below this lies the deep sea, spanning roughly 1000–6000 meters (bathypelagic to abyssal zones), with deeper hadal trenches...

Freshwater systems such as streams, rivers, and lakes exhibit distinct physical and biological characteristics that influence their microbial communities. These environments are broadly categorized into lotic systems—those with flowing waters like streams and most rivers—and lentic systems, which include still or slow-moving waters such as lakes, ponds, and marshes.In lentic systems, phytoplankton drive primary production, generating autochthonous organic carbon. In contrast, lotic...
