Brief Description of Research Dr. Nohara's expertise lies in wetland ecology, plant ecology, analysis of stable isotopes, and environmental assessment. He has visited most of the waterfronts in Japan, including Kushiro Marsh, Akai Wetland, Ozegahara Marsh, Miomote River, Lake Kasumigaura, Hinuma Bog, Banzu Natural Tidal Flat, Ise Bay, and Ishigaki Island. He has devoted his life to the study of red snow in early spring and Elodea nuttallii in summer in Oze Swamp.
ˇˇRecently, he has been working on biodiversity research. He is also working on a survey of anthropogenic influences on ecosystem functions by extracting the unit construction of salt marshes, tidelands, and marine forests in estuaries from landscape ecological and hydrogeomorphological perspectives using airplane remote sensing, and by clarifying material circulation functions, including primary production and degradation rates, and distribution and community structures for each unit. In addition, he has been assessing the impacts of human disturbance on upstream regions and determining the environmental factors, such as sediment deposition, that may have an effect on ecosystem changes.
ˇˇBased on these studies, he is working on clarifying biodiversity issues and anthropogenic influences on material cycles in salt marshes, tidelands, and marine forests in estuaries according to the stable carbon and nitrogen isotope ratios.
