[demographic development of lymnaea (galba) truncatula müller in haute-vienne, france. about observations on 4 years (1973-1976) (author's transl)].	notes on the influence of shallow drainage and predation by zonitoides nitidus on lymnaea truncatula populations in 4 types of habitats. the populations of snails are observed with large and perceptibly constant numbers by the regular maintenance of drainage. irregular maintenance is followed by a gradual fall of numbers of snails with their rapid increase in the year following autumnal ditch-digging. grass-mowing of swampy meadows at the beginning of summer drying distinctly restricts numbers o ...	1977	603201
fasciola hepatica: the developmental patterns of redial generations in naturally infected galba truncatula.	a retrospective study on 1,211 snails naturally infected with fasciola hepatica in central france was carried out to determine the numbers of full-grown sporocysts from which infections derived, to specify the developmental patterns of redial generations (normal or abnormal) and to count live and free rediae. in the department of haute vienne (siliceous subsoils), most snails showed single-sporocyst infections, with normal (46.3%) or abnormal (33.9%) development of redial generations. two-sporoc ...	2004	15338285
