| Outline of Final Research Achievements |
In recent years, floating leaved plants such as Trapa spp. have grown abundantly in many shallow lakes of Japan. Toward wise ecosystem management, we examined the influence of floating plant growth on lake ecosystems.
It was shown that dense bed of floating leaved plant causes decrease of dissolved oxygen concentration. On the other hand, investigations at Lake Inba suggested that the beds of Trapa natans provided important habitats for zooplankton, crustaceans, fish and birds. In ecosystem management, it is important to evaluate both positive and negative aspects.
