Peculiarities of the species composition and seasonal dynamics of ciliofauna in summer-autumn period in freshwater reservoirs of the lower current of the Taranay river (southern part of Sakhalin island)
Background. Despite the wide distribution of many types of ciliates, ciliate communities in each regionare formed with their own characteristics, depending on the specific environmental conditions. Study of the freshwater ciliofauna of Sakhalin island before our research has not been conducted. For...

Despite the wide distribution of many types of ciliates, ciliate communities in each regionare formed with their own characteristics, depending on the specific environmental conditions. Study of the freshwater ciliofauna of Sakhalin island before our research has not been conducted. For the first time, on the example of three small reservoirs and two watercourses, the features of the ciliate community of freshwater objects in the autumn in the southern part of Sakhalin island were investigated.

The material was collected in 2020 by randomized sampling in small water bodies of the old type and in watercourses located in the lower reaches of the Taranay river (southern part of Sakhalin Island). Samples were taken into plastic non-specialized wide-mouth samplers with a volume of 500 ml by scooping up water together with a small layer of soil and dead macrophytes, as well as 100 ml by spilling 20 liters of water from the reservoir through the Apshtein plankton net.

Of the species discovered in autumn, only 53 were found in this area in the summer. 115 species of ciliates in the study area in total were found.
