按照答辩会议程，三位博士系统介绍了学位论文的研究背景与意义、技术路线、研究内容、研究结果、研究展望等，展示了自己在博士期间的研究工作与所获得的研究成果：

覃祯俊博士学位论文的题目为：《南海珊瑚对全球气候变暖的适应性：珊瑚-微生物共生体的证据》；

郭靖博士学位论文的题目为：《广西北部湾近岸海域氮生物地球化学过程及营养盐沉积记录》；

黄金清博士学位论文的题目为：《岭鳅属团洞穴鱼类系统演化、分类厘定和动物地理学研究（鲤形目：条鳅科）》。

答辩委员们认真听取了各位博士研究生的汇报，就学位论文的相关内容进行了提问、交流与建议，答辩人对相关问题进行了回答和补充。答辩委员认为三位博士研究生在攻读学位期间取得了显著的成绩，圆满完成了博士研究生阶段的培养内容。答辩过程严谨、规范，同时借助网上平台为学院内外60余名师生提供了观摩和交流的机会，增强了学院的学术氛围。

这是广西大学珊瑚礁研究中心自2014年成立以来毕业的第2批博士研究生，此次博士学位论文答辩的顺利进行再次体现了珊瑚礁研究中心在研究生培养方面的能力。（王浩、周剑/图、文；范天来/编辑）
