Mesocosm Study Enclosures, China Mesocosms Laboratory Experiments to Tackle China's "Green Monster" Toxic Cyanobacterial Blooms Four out of five of China's largest lakes as well as vast number of its smaller lakes and reservoirs are under siege of rapidly proliferating toxic cyanobacterial blooms (Picture 1); largely attributable to nitrogen and phosphorus over-enrichment resulting from its accelerating urban, agricultural and industrial expansion. Researchers from the Universities of NC-Chapel Hill, Texas, Northeastern, Wright, and Tennessee, Knoxville, are working with Chinese collaborators at the Nanjing Institute of Geography and Limnology Chinese Academy of Science, employing outdoor mesocosms (Picture 2) in which nutrient manipulations (additions and reductions) are conducted to determine which nutrients are controlling or "limiting" blooms and to establish specific nutrient-bloom thresholds as a guideline for setting nutrient reduction targets. They are also investigating cyanobacterial and associated microbial community functional and compositional responses to these manipulations, and the roles of sediments as "internal" stores of nutrients. This work is supported by the US and Chinese National Science Foundations and the Chinese Ministry of Science and Technology.

Water quality managers can use this paper to better understand when and how to utilize algae as indicators of nutrient pollution in stream ecosystems.
