Using online reports of seahorse seizures to track their illegal trade
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Illegal wildlife trade (IWT) is a persistent and extensive threat to global biodiversity. Hundreds of marine fish species are subject to regulation under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but it is unclear how much protection species gain from CITES because information on marine fish ...

The Expression of PolySia/TriSia Associated Proteins and Genes on Developing Brain and the Effect of Dietary Sialic Acid Intervention in Piglets [PDF]
, 2015 摘要 研究背景：唾液酸（Sialicacid,Sia）是一类九碳单糖神经氨酸的总称，在细胞表面发挥其多种生物学功能。在体内，Sia通常以游离唾液酸、聚唾液酸（多聚/寡聚）、唾液酸衍生物（糖蛋白，糖脂）这三种形式存在。多聚唾液酸（polySialicacid,ploySia），一种唾液酸残基通过α2-8键连接而成的线性聚合物，广泛分布于在哺乳动物神经系统中，它的主要蛋白载体是神经细胞粘附因子（Neuralcelladhesionmolecule,NCAM）。PolySia-NCAM在细胞迁移、神经突生长 ...

Improvements for better scaling of locally managed marine areas
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract To protect and restore ecosystems at the speed and scale required to meet current environmental challenges, a greater understanding of how conservation initiatives spread from existing to new adopters is required. According to the diffusion of innovation theory, positive adopter‐to‐peer communication is a powerful driver of innovation spread ...

Zhongguo shiyan zhenduanxue, 2009 目的探讨运动环境干预对低水平铅暴露小鼠海马神经细胞结构影响的特点。方法将离乳后的40只ICR雄性小鼠,随机分为:对照组非运动环境、对照组运动环境和实验组非运动环境、实验组运动环境四组,每组10只各放入76 cm×61 cm×46 cm的笼子内饲养8周。实验组均饮用铅浓度为0.2%的水染毒建模;运动环境是在设有跑车等运动装置下运动。利用原子吸收法进行血铅和脑海马铅的测定;采用H.E染色法对海马神经结构变化情况进行病理学解析。结果血铅和海马铅水平,实验组明显高于对照组 ...

Integrative Conservation, Volume 4, Issue 3, Page 430-441, September 2025.Our study identifies southern China, including mountainous regions and islands, as key areas rich in phylogenetic diversity, and phylogenetic endemism of lizards that are currently under‐protected. Current protected areas however do not adequately cover regions that are critical for preserving the evolutionary history of lizards.

Integrative Conservation, Volume 4, Issue 3, Page 476-490, September 2025.The leaf functional traits of angiosperms and gymnosperms in mountain ecosystems significantly influence phyllosphere fungal diversity. These traits are critical for understanding fungal stress resistance and elevational adaptation, which aids in predicting plant responses to climate change.

The neuronal cell cycle regulation mechanism and related animal model in Alzheimer’s disease [PDF]
, 2015 阿尔茨海默病（Alzheimer’sDisease，AD）是一种与年龄相关的神经退行性疾病，它的主要临床表现是记忆和认知功能的逐渐衰退。AD是一种严重影响人类健康的神经退行性疾病，至今仍未找到有效的治疗方法。因此从预防和早期治疗角度考虑，对于AD早期病理变化的研究就十分重要。成熟神经元处于细胞周期静止期，而在AD中，大量神经元的细胞周期被重新激活，但这些神经元不会再分裂而是最终走向了凋亡，这是目前在AD小鼠模型中已知最早的细胞功能紊乱。但对细胞周期重新激活导致神经元凋亡的机制目前还不清楚 ...

Wildlife Letters, Volume 3, Issue 2, Page 73-83, June 2025.Blue sheep in Dhorpatan Hunting Reserve prefer alpine grasslands at 3800–4200 m on south‐facing slopes near water resources, favoring areas with low tree cover and dense ground cover, particularly rhododendrons, junipers, and Cyperaceae grasses. Their habitat significantly overlaps with livestock.
