摘要1989年9月，对美国加州近海的纳米浮游生物群落进行了定性和定量调查，发现了一个由40多个类群组成的多样的鞭藻群落，其中3个为新种（Acanthocorbis haurakiana sp. nov、Parvicorbicula zigzag sp. nov和Stephanoeca apheles sp. nov）。对物种分布模式的生物地理学分析表明，加利福尼亚鞭藻动物群由准世界性分布的物种组成，在其上叠加着一些与温暖水域有关的物种。基于相对丰度计数的站间聚类分析表明，陆上站与海上站形成的聚类显著不同。物种矩阵对物种PSI值的聚类显示了两个显著的聚类，一个是由整个研究区发现的物种组成的，另一个是由整个研究区发现的物种组成的。
Abstract A qualitative and quantitative survey of nanoplankton communities at offshore Californian localities sampled during September 1989, has revealed a diverse choanoflagellate community consisting of more than 40 taxa, three ofwhich are described as new species (Acanthocorbis haurakiana sp. nov., Parvicorbicula zigzag sp. nov. and Stephanoeca apheles sp. nov.). A biogeographic analysis of the distributional patterns of species encountered indicate that the Californian choanoflagellate fauna consists of species with quasi-cosmopolitan distribution, on top of which is superimposed a contingent of species otherwise associated with warm water regions. A station by station clustering analysis based on the relative abundance counts showed that onshore stations formed a cluster that was significantly different from that formed by offshore stations. Clustering of the PSI values for the species by species matrix revealed two significant clusters, one formed by species found throughout the study area, and one ...
