Ecological Function and Environmental Adaptation Mechanisms of Pelagic Archaea in Typical Areas of China Seas [PDF]
, 2010 浮游古菌是海洋微型生物的重要组成之一。在真光层以下的深海大洋，海洋泉古菌MarineGroupI（MGI）类群的生物量可占总原核生物量的20%。最近，环境基因组学研究的突破性进展和海洋泉古菌MGI类群纯培养株系的获得揭示出大部分MGI类群都是氨氧化古菌（Ammonia-OxidizingArchaea,AOA）。由于MGI类群是海洋中数量最为丰富的微型生物之一，其必然在海洋碳、氮循环中起着重要作用，目前AOA已成为环境微生物生态学的研究热点之一 ...

New Phytologist, Volume 247, Issue 1, Page 144-159, July 2025.Summary Domesticated chickpea cultivars exhibit limited genetic diversity. This study evaluated the effects of chickpea domestication on phosphorus (P)‐use efficiency (PUE) under low‐P conditions, using a diverse Cicer collection, including wild species. Two wild Cicer species – 54 C. reticulatum accessions and 15 C. echinospermum accessions, and seven

野生动物学报, 2019 大型猫科动物是顶级捕食者，它的存在依赖该地区的整个生态系统，也可以对整个地区的生态系统直接或间接产生强烈的影响。种群遗传学是保护遗传学的一个重要组成部分，对于野外种群来通过种群遗传学研究能了解种群的遗传多样性，种群大小，遗传结构等诸多信息。微卫星标记方法结合非损伤性取样方法在野生大型猫科动物保护遗传学的研究中有着重要地位，它具有诸多优点，广泛应用于种群遗传多样性、个体识别、亲缘关系鉴定等方面的研究。本文回顾大型猫科动物与微卫星标记方法的应用，虽然目前微卫星标记方法仍然具有一定的局限性，但是随着技术的发展，

Genetic Diversity Analysis of Five Populations of Paphia undulata [PDF]
, 2016 采用形态特征和微卫星分子标记对采自菲律宾(PH)、泰国(TH)、福建云霄(YX)、海南儋州(HN)和广西北海(BH)的5个地理群体的波纹巴非蛤(Paphia undulata)进行遗传多样性分析.形态差异分析结果显示,国外群体和国内群体形态差异明显:2个国外群体(PH和TH)形态接近,聚为一支;国内支系中,YX和HN群体的形态较近,先聚为一支,而BH群体的外部形态与前两者差异较大.Hardy-Weinberg平衡检验检测到所有群体在5个位点上均出现不同程度地偏离平衡.5个群体间遗传分化指数(FST,0 ...

小扭口藓(Barbula indica)芽胞发育特征的实验研究 [PDF]
, 2005 在光照培养箱中人工对照培养小扭口藓(Barbulaindica(Hook. )Spreng)的芽胞,显微镜下观察并记录其发育成配子体的全过程。结果表明:小扭口藓芽胞在3 ~4d即可萌发; 10d左右开始分化出绿丝体、轴丝体及假根; 18d,轴丝体上的侧枝顶端细胞以分生缢割的方式产生单细胞或多细胞芽胞; 40d,轴丝体上开始出现配子体原始细胞;之后,配子体原始细胞发育成桑椹状的幼小配子体。还对芽胞形态发育、生理生态及配子体发生过程的特点进行了分析和讨论。，CN 23-1480/

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.
