INFLUENCE OF SOIL ON THE GROWTH OF THE LAND SNAIL HELIX ASPERSA. AN EXPERIMENTAL STUDY OF THE ABSORPTION ROUTE FOR THE STIMULATING FACTORS

Transfer of elements relevant to nuclear fuel cycle from soil to boreal plants and animals in experimental meso- and microcosms

“…P-values b 0.05 are shown in bold font. direct soil contact has been reported also earlier (Gomot et al, 1989). In contrast to U, concentrations of Co, Mo, Ni, Pb and Zn in snail tissues did not depend on the presence of soil in our microcosm experiment.…”

Influence of egg cannibalism on growth, survival and feeding in hatchlings of the land snail Helix aspersa Müller (gastropoda, pulmonata, stylommatophora)

“…In this experiment, assimilation efficiency was similar to those recorded by Charrier and Daguzan (1980) and Lamotte and Stem (1987 (Pallant, 1974 (Desbuquois, 1991) and snails' density (Dan and Bailey, 1982;Gomot et al, 1989;Lucarz and Gomot, 1985) are known to influence the growth of H aspersa. In contrast to this experiment, farm snails are fed with a compound food and maintained in group at an optimum density.…”

How terrestrial snails can be used in risk assessment of soils

“…They are characteristic of the soil surface layer, are saprophagous and phytophagous, and spend a large part of their biological cycle in contact with the soil [5]. Exchanges between soil and snails occur via both soil ingestion and absorption through the moist pedal sole (foot) [5][6][7]. They fully correspond to the criteria for relevant biological indicators [8]: Easy to sample and identify, they are distributed widely and accumulate some contaminants [9][10][11][12][13][14][15][16][17][18][19], and their ecological and physiological characteristics are well known [5].…”
