Author: А.А. Бобров

Soil samples collected by А.А. Рахлеева.

Soil samples were collected on the Lapshaginskaya Bay coast (a part of the Nilma Bay) - in 9 km south-east of the WSBS. Near the village of the Chernaya River. The studied soil samples were from the following vegetation communities: pine forest with bilberry, сrowberry and lichen; pine and spruce with bilberry, cowberry, Ledum, and green moss; spruce with rare pines, with peat moss, long moss; pine with peat moss and cloudberry; and mesotrophic sphagnum bog.

Phylum Ciliophora Doflein 1901, ciliates

Author: И.В. Бурковский

The list includes 279 species of free-moving ciliates that live in soil and water (including 15 freshwater species, often penetrating to desalinate littoral (in corner bay areas) and tolerant to long-term salinity up to 12-16 ‰. The areas of species registration: the Velikaya Salma, the Rugozerskaya bay, the Kislaya inlet, and the Chernorechanskaya bay. The list does not include free-living ciliate species living on natural or artificial substrates (Peritricha and Suctoria), commensal species (Chonotrichia), symbiotic and parasitic species that require special review and revision. The list is based on the own data of I.V. Burkovskiy, partially published (Burkovskiy, 1970; Burkovskiy and others, 1974).
