的季节分布的mixotrophic寡毛纤毛虫进行了比较，严格的异养寡毛和自养haptorid中缢虫红色，在表面沿海沃茨的利古里亚海，从1988年3月至1989年12月。结果表明：（1）混合营养型纤毛虫占总生物量的51（2）春季和夏季纤毛虫种群以混合营养型为主（平均> 60%，最高达100%）;在50 μ m的大小范围内，红色占纤毛虫生物体积的主导< 30 and >地位;（4）除了大量的Strombidium spp.，（5）色素纤毛虫的生物量与光照、兼养纤毛虫的生物量与蓝藻的生物量呈正相关。
The seasonal distribution of mixotrophic oligotrichous ciliates was compared to that of the strict heterotrophic oligotrichs and of the autotrophic haptorid Mesodinium rubrum, in surface coastal waters of the Ligurian Sea, from March 1988 to December 1989. The results show that (1) mixotrophic ciliates, which were observed year-round, average 51 % of the overall biovolume (from 45 % for cells 30 to 50 mum to 57 % for cells > 50 mum); (2) mixotrophs dominate the ciliate populations in spring and in summer (average > 60 %, maximum 100 %); (3) pigmented ciliates, mixotrophic oligotrichs and M. rubrum dominate the biovolume of ciliates in the size ranges < 30 and > 50 mum; (4) besides numerous Strombidium spp., 5 mixotrophic species belonging to the genera Tontonia, Laboea and Lohmaniella were observed; and (5) a positive correlation was found between biovolume of pigmented ciliates and light and between biovolume of mixotrophic ciliates and biovolume of cyanobacteria.
