Explaining the variation in 137Cs aggregated transfer factor for wild edible plants as a case study on Koshiabura (Eleutherococcus sciadophylloides) buds
Autor: Seiji Hayashi, Mirai Watanabe, Masami Kanao Koshikawa, Momo Takada, Seiichi Takechi, Mai Takagi, Masaru Sakai, Masanori Tamaoki
Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-10 (2023)
Abstract The aggregated transfer factor (Tag) is commonly used to represent the actual transfer of radiocesium from soil to wild edible plants, but the values have shown substantial variation since the Fukushima nuclear accident. To elucidate the fac

Publikováno v: Nature-Based Solutions, Vol 4, Iss , Pp 100080- (2023)
Managing legacy nitrogen (N) that has accumulated over decades of intensive agriculture is necessary to balance agricultural production and environmental conservation. Using legacy N as a resource can reduce extant legacy N. The uplands of Japan's La

Publikováno v: Geophysical Research Letters, Vol 50, Iss 8, Pp n/a-n/a (2023)
Abstract We assessed how warm air temperatures, high solar radiation, and weak wind speeds might induce hypoxia in a shallow lake during a heat wave. We simulated bottom‐water dissolved oxygen concentrations and compared concentrations in 2022 with

Varying sensitivity of mountainous streamwater base-flow $${\bf{N}}{{\bf{O}}}_{{\bf{3}}}^{-}$$ N O 3 − concentrations to N deposition in the northern suburbs of Tokyo
Autor: Kazuya Nishina, Mirai Watanabe, Masami K. Koshikawa, Takejiro Takamatsu, Yu Morino, Tatsuya Nagashima, Kunika Soma, Seiji Hayashi
Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-9 (2017)
Abstract Ecosystems of suburban landscapes (i.e., forest, inland water ecosystem) are threatened by high nitrogen (N) loadings derived from urban air pollutants. Forest ecosystems under high chronic N loadings tend to leach more N via streams. In the

Matsuzaki, Ayato Kohzu, Taku Kadoya, Mirai Watanabe, Takeshi Osawa, Keiichi Fukaya, Kazuhiro Komatsu, Natsuko Kondo, Haruyo Yamaguchi, Haruko Ando, Koichi Shimotori, Megumi Nakagawa, Toshikazu Kizuka, Akira Yoshioka, Takahiro Sasai, Nobuko Saigusa, Bunkei Matsushita, Noriko Takamura
Publikováno v: Ecosphere, Vol 10, Iss 11, Pp n/a-n/a (2019)
Abstract Agriculture faces the great challenge of developing strategies to maintain production while simultaneously reducing environmental impacts. The trade‐off between crop production and water quality services is one of the most serious issues f

Impact of clearcutting on radiocesium export from a Japanese forested catchment following the Fukushima nuclear accident.
Autor: Tatsuhiro Nishikiori, Seiji Hayashi, Mirai Watanabe, Tetsuo Yasutaka
Publikováno v: PLoS ONE, Vol 14, Iss 2, p e0212348 (2019)
Changes in 137Cs export over time following clearcutting were investigated in a Japanese forested catchment affected by the Fukushima nuclear accident. A total of 13% of the catchment area was clear-cut 2 years after the accident. Annual suspended so

Publikováno v: New Phytologist. 235:993-1004
In forest ecosystems, understanding the relationship between the vertical distribution of fine roots and residual soil nitrogen is essential for clarifying the diversity-productivity-water purification relationship. Vertical distributions of fine-roo

Convenient Sampling of Xylem Sap from Adult Tree Trunks and Analysis of Its Components
Autor: Takejiro Takamatsu, Mirai Watanabe, Masami Kanao Koshikawa
Publikováno v: Forests
Volume 14
Issue 2
Pages: 389
Sampling xylem sap, especially from adult tree trunks, is a major challenge. In this study, we developed a new sampling method and tested its efficacy for sampling xylem sap from deciduous Quercus serrata and evergreen Cryptomeria japonica. The water
