Shuitu Baochi Xuebao, 2006 拟议中的“引江济淮”调水工程涉及到长江、淮河两大河流，瓦埠湖为其中的一个重要湖泊，其水质是否受到调水的影响为该工翟关注的环境问题之一。分析了外界环境因子变化对瓦埠湖底泥在不同环境条件下以及干、湿沉积物样品磷释放的差异，环境因子分别选取了不同磷浓度的上覆水、光照、pH、温度、DO、微生物、水体扰动等。结果表明：湿样释磷能力明显高于风干样品；上覆水体磷的浓度对底泥释磷能力有较强的调节作用；光照对底泥释磷影响不明显，但温度对底泥的释磷有较明显的影响，磷的最大释放量与之呈正相关 ...

Studies on Reproductive Behavior, Embryonic Development and Gonad Development of the White-spotted Bamboo Shark（Chiloscyllium plagiosum Bennett, 1830）in the Southern Waters of Fujian [PDF]
, 2010 本文以条纹斑竹鲨（Chiloscylliumplagiosum）为研究对象，在暂养条件下观察和记录其生殖行为、胚胎在孵化期内不同时间的发育状况；并运用组织学方法研究了条纹斑竹鲨原始生殖细胞（PGCs，primordialgermcells）的形成和变化，及其性分化的过程。本实验的主要结果如下： 1、条纹斑竹鲨的求偶和交配过程可以分为游弋、雄性鳍脚弯曲、雌雄交配和雄性鳍脚抽离四部分。游弋在整个过程中占的时间最长；雌、雄鱼在确认交配信息后，雄鱼鳍脚发生弯曲；随后不久，进行交配；交配完毕后 ...
