日本广泛培育的褶皱臀尾轮虫(Brachionus Plicatilis)两个最普通的品系是S型品系和L型品系。由于在一个野生种群中发现了这两个品系,因而在驯化期间其分化的可能性是可以排除的。在自然分布下其分布区重叠也进一步得到证实。但这两个品系的轮虫在野生条件下的生态差异尚未见报道,因此,本文对这两个品系轮虫种群的季节性变动进行了研究。野生褶皱臂尾轮虫采自三重县松坂市金刚川河口附近的一口养鳗池(面积约15亩,已暂停养鳗5
The two most common strains of Brachionus Plicatilis, widely cultivated in Japan, are the S-type and the L-type. Due to the discovery of these two lines in one wild population, the possibility of their differentiation during domestication can be ruled out. In the natural distribution of its distribution overlap is further confirmed. However, ecological differences between the two strains of rotifer in wild conditions have not been reported yet. Therefore, the seasonal changes of rotifer population in these two strains were studied in this paper. Wild cocklebur beetles were collected from a feeding eel pond (about 15 acres) near the Kongcheon estuary of Matsuzaka City, Mie Prefecture. The eel 5 has been suspended
