Therefore, it is impossible for M. mongolica to dominate in zooplankton community in oligotrophic coastal waters. Our results suggest that ecological effects of M. mongolica on structure and function of food web are neglectful in oligotrophic nearshore waters, however, dynamics of population of this species in eutrophic coastal waters and its ecological effects require a further careful investigation.

根据上述结果我们初步推断：蒙古裸腹溞在贫营养型的海洋沿岸带水域中形成较大的自然种群并对近海食物网结构和功能产生重大影响的可能性不大，但该溞在富营养化近岸水域中的种群动态及生态学效应有待进一步研究。

Induced by 4℃ low temperature, Escherichia coli inoculated in water can enter the viable but nonculturable state; in the room temperature, Escherichia coli may keep culturable state for a long period; eutrophic culture media of TSA can produce more bacteria count compared with oligotrophic culture media of PCA; evaluating the bacteria count Escherichia coli in water by plate count method may underestimate the risk of intestinal pathogen contamination.
