人工林における野ネズミの生息状況および微生息環境選好性

, 2006
2006-12人工林の構造の相違と野ネズミの生息状況との関係および人工林内での野ネズミの利用環境,すなわち微生息環境に対する選好性を明らかにし,これらを野ネズミの格間で比較した.捕獲された野ネズミはアカネズミ,ヒメネズミ,およびスミスネズミであった.アカネズミは森林構造の相違に関わらず生息し,さらにその中で様々な微生息環境を利用していた.ヒメネズミは森林構造の相違に関わらず生息していたが,人工林内において倒木の多い場所などを高頻度で利用していたOスミスネズミは沢沿いの調査区のみで捕獲され ...

Wild Pigs (Sus scrofa) Stand Their Ground: Investigating Flight Response, or Lack Thereof, to Perceived Predation Risk 野猪坚守原地:探究其面对感知捕食风险时的逃逸反应 (或无逃逸行为)

Wildlife Letters, EarlyView.
We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.

L2 Chinese Grammatical Acquisition and Processing: A Substantive and Methodological Review

International Journal of Applied Linguistics, EarlyView.
ABSTRACT This study presents a systematic review of 92 empirical studies on Chinese as a second language (CSL) in grammatical processing and development, synthesizing their substantive foci and methodological characteristics. The results reveal consistent scholarly attention to cross‐linguistic topics, with less focus on features that are distinctively

Leaf C:P ratio as a universal indicator of photosynthesis in subtropical woody species: Stoichiometric thresholds and metabolic trade‐offs

Functional Ecology, Volume 40, Issue 7, Page 2332-2344, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric ratios of carbon (C), nitrogen (N) and phosphorus (P) serve as important indicators for assessing nutrient balance in forest ecosystems, but their relationships with photosynthetic dynamics require deeper characterization.

Threats to the World's Bears and Efforts to Conserve Them: Perspectives and Actions of IUCN Bear Specialist Group Members 世界熊类面临的威胁及其保护努力:IUCN熊类专家组成员的观点与行动

Integrative Conservation, Volume 5, Issue 2, Page 177-191, June 2026.
A survey of IUCN Bear Specialist Group (BSG) members revealed that habitat loss, degradation and fragmentation is the greatest threat to each of the 7 species of terrestrial bears. Poaching and human–bear conflicts are also high threats for some of these species.

北海道中央部の針葉樹人工林における風倒被害と樹形 [PDF]

, 2011
本研究では，樹木あるいは林分の風倒抵抗性に対する樹形の効果について検討するため，北海道中央部で2004 年に風倒被害のあった地域の針葉樹人工林で，被害の発生と樹形の関係について調査した。カラマツ，トドマツ，エゾマツ人工林を対象に，風倒後2 〜4 年後に，被害林と無被害林で調査し， 形状比，樹冠長率（樹冠長と樹高の比），相対風心高（風心高と樹高の比）について検討した。カラマッ人工林とトドマツ人X 林では，平均形状比は被害林分と無被害林分で分離し，無被害林分で小さかった。樹冠長率と相対風心高の結果から ...

First‐trimester prediction and prevention of preterm pre‐eclampsia in women with chronic hypertension

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 5, Page 613-622, May 2026.
ABSTRACT Objectives To evaluate the effect of aspirin on gestational age at delivery due to preterm pre‐eclampsia (PE) in women with chronic hypertension (CH), to assess the predictive performance of the Fetal Medicine Foundation (FMF) first‐trimester competing‐risks model for preterm PE in this high‐risk group and to evaluate how parity, previous PE ...

三重大学平倉演習林スギ人工林におけるスギリター被覆率と土砂移動の関係について [PDF]

, 2018
山地斜面において土砂移動の抑制効果が期待される林床被覆状態について，リターが分解・流出しやすいヒノキ人工林や，シカ食害によって下層植生が乏しくなったブナ林での検証事例がある一方，リターが長期的に残存するスギ人工林での検証は多くない。本研究では，スギ人工林斜面に残存するリターが土砂移動を抑制する効果について，リター被覆率と移動土砂量の関係から検討した。その結果，約3年間のプロット観測でスギリター被覆率が大きいとき移動土砂量が少なくなり一定の抑制効果が認められた。また ...

‘The Heart of the Matter’: Grandparent Childcare in Contemporary Chinese Families

Children &Society, Volume 40, Issue 3, Page 556-566, May 2026.
ABSTRACT Grandparent childcare is an international phenomenon, especially within families with children under 3 years old. China is no exception, as shown by a number of quantitative studies. Less clear is our understanding of the actual childcare arrangements involved and how these are negotiated and sustained through the intergenerational ...
