More specifically, effects of dam construction, sediment release and other human activities on nutrient recycling and physic-chemical characteristics of substrate and its subsequent effects on plant composition of the respective floodplain. I am also interested in the succession, colonization and competition mechanisms of native and exotic invasive plants. Lately I have been working on the phytoremediation of heavy metals from water by using Charophytes. I am also working on the process of mycorrhizal association with riparian plants in a view to investigate the role of mycorrhiza on the succession of these plants. I have also a target to test the heavy metal removal from wetlands and riparian soil by using symbiotic mechanism of riparian plants of arbuscular mycorrhizal fungi.●More research is needed for sustainable environmental restoration.●It is always a better idea to develop a system where the ecosystem can be kept functional by its own. ●Use of plants to remove toxic elements from the environment (phytoremediation) need more study. ●Charophytes absorb hazardous metals (arsenic, cesium, etc.) and clean water.●The metals removal efficiency can be improved by contorting calcification of charophytes.●Decomposition process of charophytes in water body is very slow. Therefore, it can be a potential agent for phytoremediation.【最近の研究テーマ】●Investigation on the effect of monoclonal plantation of mangroves on ecosystem and possible ways of mitigation.●Development of submerged plant distribution model based on stress tolerance??https://www.researchgate.net/prole/Md_Harun_RashidMD Harun OR Rashid(エムディハルンオルラシッド) 助教大学院理工学研究科 環境科学?社会基盤部門 環境科学領域ライフ95
