| Outline of Final Research Achievements |
Pollen composition in sediments is used for estimating paleoenvironmental change through Quaternary period because of its well preservation. Stable isotopic composition of pollen has also been proposed as paleoclimate indicators such as precipitation while the utility of this approach has not yet been confirmed for many plant species and regions. In this study, modern tree pollens that frequently appear in Holocene lake sediments in Japan were collected throughout the mainland and analyzed for carbon isotopic compositions to test their potential as a paleoclimate proxy. Some tree species such as a pine (Pinus densiflora) showed significant correlation between carbon isotopic composition and several types of meteorological data. The results suggest that carbon isotopic composition of pollen grains of the specific species from sediments could be used as local-scale paleoclimate proxies in Japanese archipelago.
