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。
Eighty-four of the 44 rotifer species found in the Gaozhou Reservoir (1988) are dominant. They are Spiraecoides rotundifolia, Sparus multiforme rotifers, Spindle rotundiformes, Rotifers rotundifolia, Rotiflorus rotundifolia, Rotundiflora rotundiformes, Oviform rotifer and True-wing multiple rotifers. Among them, the remaining species appeared throughout the year, except for the Staghornia brasiliensis, Crataegus pinnata and Triceratops spp. The population density of the eight species was 46.1 individuals / liter. Their individual population accounts for 83.8% of the total number of rotifers. The density of summer and autumn was the highest in one year, accounting for 41.2% and 39.6% respectively, while the density of spring and winter was the lowest with 10.7% and 8.5% respectively. The paper also discusses the amount of suitable temperature amplitude and the distribution of these eight rotifer species and water quality.
