| 摘 要： | 高州水库(1988)发现的44种轮虫中有8种为优势种。它们是螺形龟甲轮虫、针簇多肢轮虫、圆筒异尾轮虫、奇异巨腕轮虫、裂痕龟纹轮虫、卡顿圆筒异尾轮虫、卵形彩胃轮虫和真翅多肢轮虫。它们中除奇异巨腕轮虫、裂痕龟纹轮虫和真翅多肢轮虫外,其余的种类全年出现。8种的种群密度为46.1个/升。它们的个体数量占轮虫总量的83.8%。一年中以夏、秋密度最高,分别占41.2%和39.6%,而春、冬密度最低,各为10.7%和8.5%。文中还讨论了这八种轮虫各种高峰形成的量适温幅以及它们的分布与水质的关系。

| Abstract: | This paper is the second part of Rotatorian survey in Gaozhou Reservoir(1988).Among the 44 recorded Rotatorian species,8 species of them are dominant Rotatoria,suchas Keratella cochlearis(Gosse),Polyarthra trigle Ehrenberg,Trichocerca cylindrica(Imhof),Pedalia mira(Hudson),Anuraeopsis fissa(Gosse),Trichocerca cylindrica chattoni(De Bea-uch),Chromogaster ovalis(Bergendal)and Polyarthra euryptera(Wierzeiski).They occurthe whole year except Pidalia mira(Hudson),Anuraeopsis fissa(Gosse)and Polyar-thra euryptera(Wierzeiski).The population density of the eight species was 46.1 ind/1.the number of individuals of them were 83.8 percent of the total sum of Rotatoria,There were two maxima of the population density-41.2% in summer and 39.6% in au-tumn,and two minima-10.7% in spring and 8.5% in winter.In this paper,we also discuss the optimum temperature ranges formed by the eightrotifers during the maxima of each one and the relationship between their occurence andwater quality. |
