Sakashita W, Imamura N, Sato T, Yagihashi T, Tsuneoka R, Sakata T, et al.
J Environ Radioact . 2025 Mar; 285:107656. PMID: 40058331
Accurate measurement of the amounts of radiocesium (Cs) that transfer from the canopy to the forest floor at the recent quasi-equilibrium state is crucial for improving the accuracy of long-term...

Sakashita W, Manaka T, Tsuneoka R, Sakata T, Imamura N, Nagakura J, et al.
J Environ Radioact . 2025 Mar; 284:107653. PMID: 40037134
To accurately predict long-term Cs activity concentrations in stem wood, it is crucial to assess whether the Cs cycle in forests has reached quasi-equilibrium between trees and forest soil. A...

Ohmae Y, Sakashita W, Sakata T, Imamura N, Miura S, Akama A, et al.
J Environ Radioact . 2024 Jan; 273:107390. PMID: 38295586
Removal of litter-associated Cs from the forest floor (litter removal) can reduce the Cs uptake by plants; however, the proposed effective period for litter removal was 1-2 years after the...

Sakashita W, Imamura N, Sakata T, Tsuneoka R, Shinomiya Y
J Environ Radioact . 2024 Jan; 273:107385. PMID: 38244324
The radiocesium (Cs) activity concentration in stemflow, which is an element of the Cs cycle in the forest, is determined by the supply of Cs from the outer bark and...

Manaka T, Araki M, Ohashi S, Imamura N, Sakashita W, Ogo S, et al.
Sci Rep . 2023 Jun; 13(1):9144. PMID: 37277410
Radiocesium (Cs) released in the Fukushima Dai-ichi Nuclear Power Plant accident is still cycling in the forest ecosystem. We examined the mobility of Cs in the external parts-leaves/needles, branches, and...

Zheng J, Sakata T, Sukartiningsih , Fujii K
Sci Total Environ . 2022 Dec; 862:160916. PMID: 36526175
Tropical regions are hotspots of increasing greenhouse gas emissions associated with land-use change. Although many field studies have quantified soil fluxes of nitrous oxide (NO; a potent greenhouse gas) from...

Manaka T, Komatsu M, Sakashita W, Imamura N, Hashimoto S, Hirai K, et al.
J Environ Radioact . 2022 Aug; 251-252:106967. PMID: 35930867
To elucidate interannual changes in the vertical distribution of Cs in forest ecosystems contaminated by the Fukushima Dai-ichi Nuclear Power Plant accident, we investigated Cs inventories in forest soils (both...

Ishihara Y, Sakai S, Yamakawa T, Inoue T, Suzuki M, Sakata T, et al.
Annu Int Conf IEEE Eng Med Biol Soc . 2020 Jan; 2019:4372-4375. PMID: 31946836
In this study, a multimodality probe that simultaneously measures electroencephalograms, cerebral hemodynamics, and brain surface temperature was developed. This probe has six channels, and each channel has a platinum electrode...

Sakata T, Oda S, Tsunaga Y, Shomura H, Kawagishi-Kobayashi M, Aya K, et al.
Plant Physiol . 2014 Feb; 164(4):2011-9. PMID: 24569847
Microsporogenesis in rice (Oryza sativa) plants is susceptible to moderate low temperature (LT; approximately 19°C) that disrupts pollen development and causes severe reductions in grain yields. Although considerable research has...

Exp Appl Acarol . 2012 Sep; 59(4):391-408. PMID: 23011106
The community structures of Mesostigmata, Prostigmata, and Oribatida in the soil of broad-leaved regeneration forests and conifer plantations of various ages were assessed alongside soil and plant environmental variables using...
