Zhongguo shiyan zhenduanxue, 2011 目的探讨丰富环境干预对短暂性全脑缺血大鼠海马形态学的影响。方法将Wistar大鼠分组建立短暂性全脑缺血模型,进行丰富环境干预,进行大鼠海马形态学分析。结果 HE染色显示,与IS组相比,IE组海马CA1区组织的病理损伤明显减轻。锥体神经元排列较规则,肿胀、固缩及脱失神经元数目较少。Nissl染色显示,IS组海马细胞层数减少,神经元细胞间隙变大,排列稀疏,细胞形态异常,尼氏体大量脱失,染色浅谈且出现较多空白区;IE组海马区仅见少量神经元缺失及胶质增生,但细胞形态基本正常,细胞排列较为整齐,尼氏体较清晰 ...

Vulnerability of tropical fish communities across depth in the central Indian Ocean
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

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 ...

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 ...
