Morphology and infraciliature of some soil ciliates (Protozoa, Ciliophora) from continental Antarctica, with notes on the morphogenesis of Sterkiella histriomuscorum
Abstract The morphology of seven soil ciliate species from continental Antarctica was investigated using live observation and protargol impregnation. Observations on two populations of Protospathidium serpens corroborate the view that this species usually has a single, more-or-less nodular, macronuc...
