Hydrology and Ecological Evolution in a Permafrost Region in Northeast China Since the Late Pleistocene

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
Continuous hydrology and ecological evolution records of permafrost regions in Northeast China since the late Pleistocene (30 cal. ka BP) are obtained. Responses of hydrology and ecosystem dynamics to the climate cycle on the millennial scale and regional environmental effects related to permafrost.

Antifibrotic Activity of Diarylheptanoids fromBetula platyphyllatoward HSC-T6 Cells [PDF]

open access: yesBioscience, Biotechnology, and Biochemistry, 2012
A chemical investigation of the n-butanol fraction of the inner bark of Betula platyphylla led to the isolation of seven diarylhepanoids, (-)-centrolobol (1), aceroside VII (2), aceroside VIII (3), (3R)-1,7-bis-(4-hydroxyphenyl)-3-heptanol-3-O-[2,6-bis-O-(β-D-apiofuranosyl)-β-D-glucopyranoside (4), 1,7-bis-(4-hydroxyphenyl)-5-hepten-3-one (5 ...

Overwintering foraging tactics of sedentary sika deer in a region prone to heavy snow in northern Japan

open access: yesEcological Research, Volume 40, Issue 5, September 2025.
We present the overwintering foraging tactics adopted by the sika deer recently established in a heavy snowfall region of northern Japan. We found that sedentary deer adopted risk‐averse foraging by switching their dietary compositions to readily available foods under different snow conditions. In particular, when facing extreme snowfall, they depended

Ectomycorrhizal fungal community varies across broadleaf species and developmental stages

open access: yesScientific Reports
Ectomycorrhizal fungi (EMF) play pivotal roles in determining temperate forest ecosystem processes. We tracked root EMF community succession across saplings, juveniles, and adults of three temperate broadleaf trees (Acer mono, Betula platyphylla, and ...

Comparison of genetic and phenotypic variations in disjunct populations of highly polyploid Betula davurica in the Japanese Archipelago with continental populations in a region of northeast Asia

open access: yesPlant Species Biology, Volume 40, Issue 5, Page 439-451, September 2025.
Betula davurica is widely distributed in continental regions of northeast Asia but is disjunctly distributed in the Japanese Archipelago. Disjunct Honshu populations are genetically divergent from continental populations in a continuously distributed region in Primorye although disjunct Hokkaido populations are not divergent. These disjunct populations

Artificial Inoculation of Inonotus obliquus on Betula platyphylla var. japonica [PDF]

open access: yesThe Korean Journal of Mycology, 2008
Inonotus obliquus could be isolated from Betula platyphylla var. japonica with diameter in the range of 613 cm that artificially inoculated by the fungus. The diameter and/or inoculation point of tree did not show any significant relationships with the infection rate of the fungus.

Effects of Niche Marginality on Hotter‐Drought Tree Mortality in Angiosperms and Gymnosperms

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 9, September 2025.
ABSTRACT Aim Current observations of global tree mortality events associated with drought raise concerns about climate change risks to forests' dynamics and function. It is unclear which forests are more susceptible to pulses of mortality under further changing climates.

Cloning and expression of BpMYC4 and BpbHLH9 genes and the role of BpbHLH9 in triterpenoid synthesis in birch

open access: yesBMC Plant Biology, 2017
Background Birch (Betula platyphylla Suk.) contains triterpenoids with anti-HIV and anti-tumor pharmacological activities. However, the natural abundance of these triterpenoids is low, and their chemical synthesis is costly.
