[Long-term results of biological control by predation. Experimental study of population development of several species of snails (author's transl)].
The evolution of malacological fauna, which is subject to prediation of Zonitidae snails, is studied on two types of habitats of Lymnaea truncatula: swampy meadows and banks of river maintained by a periodical grass-mowing. Two years are necessary for obtaining an entire elimination of Lymnaea truncatula. Then other species of Lymanaeidae and Succinea are affected by predation, but Succinea snails do not pass away completely. The other snails are not affected or little by predation.
