文摘
Impacts of hydrological and land use changes on a floodplain lake were evaluated.
Diatom and geochemical stratigraphic records from floodplain lake were utilized.
Anthropogenic stressors promoted ecological regime shift in the floodplain lake.
Utility of paleolimnological methods to understand ecological evolution was stressed.
Study flags the need to monitor these wetlands under the Ramsar Convention.
