Vegetation history during the last 28,000 years in Tamba Highland, Kyoto, Japan based on multi-analyses of sediment from the Jaga-ike mire

open access: yesQuaternary Environments and Humans
Sediment cores obtained from the Jaga-ike mire, located in the inland mountainous area of the Kinki region in western Japan, date back to 28,000 cal BP. The vegetation history around the Jaga-ike mire since the Last Glacial period was reconstructed using

Genotype and transcriptome effects on somatic embryogenesis in Cryptomeria japonica.

open access: yesPLoS ONE, 2020
Somatic embryogenesis (SE), which is in vitro regeneration of plant bodies from somatic cells, represents a useful means of clonal propagation and genetic engineering of forest trees.

Concentrações de ácido indolbutírico no enraizamento de Cryptomeria japonica. [PDF]

open access: yes, 2015
Cryptomeria japonica is a conifer of great load that detaches for the fast growth and good lumber potential. In spite of could being propagated by seeds, the vegetative propagation of Cryptomeria japonica is justified for the maintenance of the desirable

Local variance of atmospheric 14C concentrations around Fukushima Dai-ichi Nuclear Power Plant from 2010 to 2012 [PDF]

open access: yes, 2017
Radiocarbon (14C) has been measured in single tree ring samples collected from the southwest of the Fukushima Dai-ichi Nuclear Power Plant. Our data indicate south-westwards dispersion of radiocarbon and the highest 14C activity observed so far in the ...

Measurement of Ungulate Palatability and Browsing Pressure on Japanese Flora

open access: yesEcological Research, Volume 41, Issue 1, January 2026.
Estimation of palatability and browsing pressure are key techniques for ecosystem management. We compared four methods to estimate palatability based on browsing scar survey and proposed the reference palatability values for the Japanese flora as plant ecological trait.

Molecular Cloning and Immunochemical Characterization of a New Japanese Cedar Pollen Allergen Homologous to Plant Subtilisin-Like Serine Protease

open access: yesWorld Allergy Organization Journal, 2010
Protease activities in allergen sources are thought to be involved in triggering allergic inflammation through the disruption of epithelial barrier or the induction of proinflammatory cytokines.

Action of Soft Rot- and White Rot Fungi on Partially Delignified Softwoods [PDF]

open access: yes, 1976
この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。Fourty-four species of softwoods were partially delignified with acidified sodium chlorite for 6 hours at 40℃ and exposed to a soft rot fungus, Chaetomium globosum KUNZE, for 8 weeks at 28℃. The weight losses after the

Relative Importance of Resource and Condition Niche for Invertebrates in Water‐Filled Treeholes

open access: yesFreshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Water‐filled treeholes offer an ideal system to disentangle the roles of resource availability and abiotic conditions in community assembly. This study hypothesized that niches related to consumable resources and microhabitat conditions play distinct roles in shaping community structure, with niche differentiation being more strongly ...

Soil pH modulates microbial nitrogen allocation in soil via compositional and metabolic shifts across forests in Japan

open access: yesiMetaOmics, Volume 2, Issue 4, December 2025.
This study reveals how soil pH regulates microbial N allocation in forest soils across Japan. We show that microbial abundance controls the overall rate of N cycling, while microbial composition and metabolic potential determine whether ammonium is released or retained.
