title: [About some observations on aestivation of Lymnaea (Galba) truncatula Müller non- or infested by Fasciola hepatica L. (author's transl)].
abstract: The authors studied vertical and horizontal distribution of L. (Galba) truncatula in two series of dry natural habitats: draining ditches, bovine footprints. The observations show:- the location of most surviving snails on ditch sides and in low parts of footprints; - the presence of broken shells (by predators) on ditch bottom and in high parts of footprints; - the existence of a connection between the infested snails distribution and parasitic development-degree: the mature infested snails are seen in lower parts of habitats than the parts of the immature infested snails.
