Wildlife Letters, EarlyView.Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Dizhen xuebao, 2020 基于广西柳州地区地震安全性评价中实测所获的钻孔资料，利用线性模型、幂函数模型和二次函数模型分别对该地区土层剪切波速与埋深之间的相关性进行了拟合分析，通过对比发现幂函数模型为二者间相关性拟合的最优选择，同时探讨了土体状态对二者相关性的影响。结果表明：除人工填土外，柳州地区内常见土层剪切波速与埋深之间具有较强的相关性，区域性对其相关性也具有影响。最后以实测钻孔为例，验证了本文模型的预测精度和可靠性，而且模型的预测精度可以通过区分土体状态得到明显提高。

Wildlife Letters, EarlyView.Human‐caused leopard deaths in Sri Lanka averaged 9.65 ± 4.5 records year−1 over 17 years (2008–2024; n = 164), with records highly clustered in the central highland mosaic ecosystem. Mortality was dominated by adult males and driven primarily by snaring in plantation landscapes, and indicating an increase approximately 0.7–0.8 deaths per year.

急性脑梗死体积与空腹血糖、血清胰岛素及胰岛素抵抗的相关性研究
Zhongguo shiyan zhenduanxue, 2000 目的全面系统地观察分析空腹血糖（ＦＰＧ）、血清胰岛素（ＦＩＮＳ）、胰岛素抵抗性（ＩＲ）与急性脑梗死体积的相 关性及其意义。方法同步采集急性脑梗死体积（ＣＴ多田氏法计算）、ＦＰＧ（特异性葡萄糖氧化酶法）、ＦＩＮＳ（放射免疫法）、 ＩＲ［Ｉｎ（ １／ＦＰＧ×ＦＩＮＳ）法］的数值，并与急性脑外伤组及正常对照组比较，组间两样本均数比较采用计量资料 ｔ检验，两变量 间关系采用直线相关分析。结果ＦＰＧ、ＦＩＮＳ、ＩＲ在急性脑梗死时与急性脑外伤时一样，与正常对照组相比明显升高 （ｐ＜ ０．０１ ...

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

Zhongguo shiyan zhenduanxue, 2015 目的分析变应性鼻炎血清特异性IgE（sIgE）及皮肤点刺实验与临床症状的相关性。方法选择80例变应性鼻炎患者,检测sIgE,同时进行标准化皮肤点刺试验,同期对患者进行症状进行评分,分析sIgE水平与皮肤点刺试验阳性程度的相关性及其与临床症状的相关性。结果1sIgE阳性强度与皮肤点刺试验阳性强度具有相关性（Kappa=0.558,P0.05）。结论 sIgE阳性强度、皮肤点刺试验阳性强度与临床症状无相关性,但两种检查方式具有一致性,对诊断、鉴别诊断变应性鼻炎具有较高的临床价值。

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root activity creates unique microbial hotspots in the rhizosphere by influencing the metabolic activities of surrounding soil microorganisms, profoundly regulating the dynamics of soil organic carbon (SOC). However, how root economic strategies affect the formation and

Zhongguo shiyan zhenduanxue, 2013 目的探讨原发性宫颈癌人群中NF-κB信号传导通路相关基因多态性与宫颈癌发生发展的关系。方法以广西壮族自治区肿瘤医院2008年9月-2009年9月收治的宫颈癌患者与健康体检者各100名为研究对象,利用限制性片段长度多态性检测法检测研究对象该通路相关基因的基因多态性,进行对比分析。结果 NF-κB信号传导通路相关基因多态性型别在两组研究对象中出现的频率无显著性差别,P>0.05;变异等位基因出现频率与以往结果相一致。结论 NF-κB信号传导通路相关基因多态性与宫颈癌的发生发展无明确的相关关系。

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.
