摘要:
本研究利用水产试验所研究船“水试一号”于2006年冬(1月)夏(7月)两季在台湾海峡海域进行水文探测及浮游动物采样, 以探讨浮游翼足类群聚组成与丰度之时空分布及其与水文环境的相关性。结果发现浮游翼足类夏季的丰度及多样性指数明显较冬季高, 而种类数则差异不大; 两季间优势种类组成相似但优势排名略有不同, 夏季主要优势种为棒笔帽螺(Creseis clava)、尖笔帽螺(C. acicula)和马蹄螔螺(Limacina trochiformis), 合占所有翼足类丰度的97%, 其中仅棒笔帽螺就占了总丰度的62%; 冬季主要优势种为胖螔螺(Limacina inflata), 占翼足类丰度的72%。翼足类丰度在空间上的分布亦有明显的季节差异, 夏季时以台湾海峡北部较高, 冬季则以南部较高。种类数与物种多样性指数则均以海峡南部较高。由水文站群分析及各站群生物及水文特征结果显示, 台湾海峡季节性水团的消长与翼足类群聚分布有十分密切的关联。
