Mechanical Evaluation of the Japanese Larch for Wind Damage

Journal of the Japanese Forest Society, 2008
本研究では, カラマツの風荷重による根返りおよび折損に関する力学的な評価を行うため, 立木の引き倒し試験を北海道十勝管内で実施した。カラマツは, 十勝における主要造林樹種であり, たびたび当地域は台風被害を受けてきた。回転モーメントと傾斜角の関係からは, 最大回転モーメント時の根元の平均傾斜角は 9.7oで, 比較的小さな傾斜角であった。最大抵抗モーメントと立木の諸因子 (胸高直径D, 樹高H, 形状比H/D, 材積D2H, 枝葉重Wcr, 幹重Ws, 全重Wt) との相関分析の結果, 胸高直径Dは, 根返りおよび幹折れのいずれの場合においても相関が高く, 立木の耐風性を示すもっとも重要な指標となることが示された。今回の結果では, 根返りに関しては, 最大抵抗モーメントは, Dの約2.6乗に比例し,

Addressing Uncertainties in Climate–Ecosystem Feedbacks in the Arctic: Ten Priority Research Questions for Integrated Observation and Modeling

Ecological Research, Volume 41, Issue 4, July 2026.
Uncertainties exist in the biosphere–climate feedbacks in the Arctic. Remote and ground measurements play complementary roles in detecting possible changes. A critical next step is identification of key drivers of the global changes for future projections. ABSTRACT Positive biosphere–climate feedbacks are likely to amplify the Arctic warming, yet major

Pest categorisation of Mycodiella laricis‐leptolepidis

EFSA Journal, 2018
Following a request from the European Commission, the EFSA Panel on Plant Health (PLH) performed a pest categorisation of Mycodiella laricis‐leptolepidis, a well‐defined and distinguishable fungal species of the family Mycosphaerellaceae.
EFSA Panel on Plant Health (PLH), Michael Jeger, Claude Bragard, David Caffier, Thierry Candresse, Elisavet Chatzivassiliou, Katharina Dehnen‐Schmutz, Gianni Gilioli, Jean‐Claude Grégoire, Josep Anton Jaques Miret, Alan MacLeod, Maria Navajas Navarro, Björn Niere, Stephen Parnell, Roel Potting, Trond Rafoss, Vittorio Rossi, Gregor Urek, Ariena Van Bruggen, Wopke Van der Werf, Jonathan West, Stephan Winter, Johanna Boberg, Paolo Gonthier, Marco Pautasso   +24 more

Development and Characterization of Polymorphic Genic-SSR Markers in Larix kaempferi

Molecules, 2015
New simple sequence repeat (SSR) markers were developed in the Japanese larch (Larix kaempferi) using unigene sequences for further genetic diversity studies and the genetic improvement of breeding programs. One thousand two handred and thirty five (1235)

H2O2 Activation and Alkane Oxidation by Copper Complexes With R‐dpa N3‐Tridentate Ligands: The Complex‐Based Dicopper Active Species as a Key Feature in the Efficient Alkane Oxidation

Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
Two reaction pathways, Paths 1 and 2, are involved in H2O2 activation by Cu complexes with N3‐tridentate ligands, depending on the ease of bridging structure formation. In Path 1, hydroxy radical (HO•) is formed from a hydroperoxo Cu(II) intermediate. In Path 2, a relevant complex‐based μ‐O• bridged Cu(II)2 active species is formed from a bis‐μ‐oxo Cu ...

Intra‐ and Interspecific Spatial Temporal Interactions Drive Habitat Selection of Three Sympatric Top Predators

Ecology and Evolution, Volume 16, Issue 6, June 2026.
ABSTRACT The population distribution and habitat selection of top predators are critically important for species conservation and habitat management. While previous studies have identified environmental characteristics and food resources as factors influencing animal habitat selection, the roles of potential intra‐ and interspecific competition have ...

Block Shear Strength and Delamination of Cross-Laminated Timber Fabricated with Japanese Larch

BioResources, 2016
Process parameters of cross-laminated timber (CLT) fabricated with Japanese larch were evaluated. The process parameters were designed by using an orthogonal test including pressure, glue consumption, and adhesive. Both delamination and block shear tests

Towards weather‐based forecasting of annual seed production in six European forest tree species

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Synthesis and applications: Seed production can be predictable with a promising degree of accuracy for six European tree species in the year prior to seed rain, if combined with on‐site monitoring of seeds, phenology, and weather. This holds value for seed harvesters, nurseries and forest managers, and may inform orchard management and public health ...

Uncovering temporal patterns of wildlife activity, habitat use and habitat preference from camera‐trap data

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1880-1895, June 2026.
Abstract An understanding of habitat use and levels of active behaviour is foundational to wildlife behaviour, ecology, conservation and management. These variables are commonly measured by tracking individuals in space and time using biologging. In principle, camera‐trap data also contain information about both activity level and habitat use; however,
