Preliminary Studies on Light Adaptation and Response to Ca2+ and pH Changes in Shallow-water Corals

Abstract

珊瑚礁生态系统拥有很高的初级生产力和生物多样性,是一类具有重要的生态功能且极为特殊的生态系统。同时,珊瑚色彩绚丽,种类多样,也具有极高的观赏价值与经济价值,在水族宠物市场备受关注。由于野外采集珊瑚的不可持续性以及对珊瑚礁生态系统的潜在破坏,目前,国内外越来越多的研究开始关注珊瑚尤其是造礁珊瑚人工养殖的环境影响因素。本文研究了不同珊瑚的光适应性,以及钙离子浓度、pH两个重要环境因子对珊瑚的影响,以便有针对性的优化珊瑚养殖系统,提高珊瑚人工养殖的效率。主要研究内容和结果如下: 1、使用调制叶绿素荧光仪(Pulse-Amplitude-Modulation)对18种常见养殖珊瑚的叶绿素荧光参数(F...Coral reef ecosystem is a type of extremely unique ecosystem in the world, with significant primary productivity, biodiversity and important ecology function. Meanwhile, corals are well known for its gorgeous color and abundant species, so corals are highly concerned in the international ornamental market. Because of the unsustainable of wild collection and potential destruction to the coral reef ...学位:理学硕士院系专业:环境与生态学院_环境科学学号:3312012115164
