“…It is not known if they are genetic, a result of phenotypic plasticity with great reaction norms, or an effect of genotype-environment interactions (FALCONER & MACKAY 1996, LYNCH & WALSH 1998. The Roman snail lays eggs several times during one season , STÊPCZAK 1992; eggs laid by breeding snails in the spring, summer and autumn differ in quality and quantity (LIGASZEWSKI et al 2007). The date of egg-lying may thus influence the size and number of eggs.…”

“…Being synanthropic in much of its range, the species is naturally influenced by anthropogenic factors. Its biology (KILIAS 1960, URBAÑSKI 1963, DZIABASZEWSKI 1975, ecology, and economic importance have been extensively studied (CADART 1955, TURÈEK 1970, £OMNICKI 1971, POL-LARD 1975, STÊPCZAK 1976, CHMIELEWSKI 2005, LIGASZEWSKI et al 2007). H. pomatia shows a wide range of shell size variation (URBAÑSKI 1963, STÊPCZAK 1982, DYDUCH-FALNIOWSKA et al 2001, ANDREEV 2006; the growth rate varies individually even among snails from the same clutch (POLLARD 1975).…”

The experiment on adult Roman snails (Helix pomatia L.) and their offspring showed a positive correlation between the mean egg size and the parent body size. There was no correlation between the parent size and the number of eggs. A trade-off between the egg size and the clutch size was observed. The body size of juveniles at early growth stages was correlated with the parent size; later (offspring aged 2 and 3 months) there was no such correlation, suggesting maternal effect. The results are relevant to estimating the reproductive success and offspring survival rate at early stages.

“…In studies conducted earlier, in 2003, among the population from Balice discussed here it was determined that the shell diameter was correlated in ascending order in a highly statistically significant manner with such features of the clutch as clutch weight and mean weight of an individual egg. The Roman snails gathered during that study had a mean shell diameter of 24.1 mm (Ligaszewski et al, 2007), while the snails used in the study currently under discussion from 2006 had a smaller diameter amounting only to 33.9 mm on average. Therefore, such features of snail egg clutches in greenhouse conditions as clutch weight, number of eggs in a clutch, mean weight of an individual egg, and ration of clutch weight to breeder weight were generally lower values in the snails discussed in this study than in the study conducted three years earlier (Tab.…”

“…These were successfully continued in conjunction with multi-year studies aimed at developing principles for active protection of a selected local natural population of Roman snails. The basis for this protection was the introduction into the natural habitat of partially reared hatchlings from this same population which had been obtained on a mass scale in farmed conditions (Ligaszewski et al, 2005, Ligaszewski et al, 2007, Ligaszewski et al, 2014a, Ligaszewski et al, 2014b, Ligaszewski et al, 2016. These studies allowed for the determination of the precise values and fluctuations of such values as clutch weight, number of eggs in clutch, mean weight of a single egg, ratio of clutch weight to breeder weight, and seasonal variability in the intensity of reproduction.…”

The aim of this study was to compare the quality of clutches and reproduction results of two groups of Roman snails (Helix pomatia) from the same local population, laying eggs simultaneously in semi-natural farm conditions and in a natural habitat. The study material were Roman snails aged 2 or more years which had entered the third phenological season of their life and thus the first season of sexual maturity. Observations were conducted at an earthen enclosure in a greenhouse belonging to the experimental farm for edible snails at the National Research Institute of Animal Reproduction in Balice near Kraków (Poland) as well as at a site where a local population naturally occurs in the uncultivated park surrounding the Radziwiłł Palace. In the June-July season, differences among such parameters as weight of clutch, number of eggs in clutch, mean egg weight, and hatchling percentage when compared to the total number of eggs in the clutch were compared. It was determined that clutches of eggs from the natural population laid in the greenhouse were of lesser weight (P<0.01), contained fewer eggs (P<0.05), and the mean weight of individual eggs was less (P<0.05) than in clutches laid simultaneously in a natural habitat. Both in the greenhouse and the natural habitat, in the first phase of laying eggs (June) the weight of the clutch and number of eggs its contained were greater than in the second phase (July). However, only for snails laying eggs in the greenhouse were these differences statistically significant (P<0.05) and highly significant (P<0.01), respectively. Statistically significant differences were not observed in hatchling percentage between eggs laid in the greenhouse and the natural habitat. The lower number of eggs laid in the farmed conditions of the greenhouse was successfully compensated for by the absence of mass destruction by rodents which occurred in the natural habitat.

“…Besides the size-specific fecundity, size was experimentally shown to have a directional effect on batch size, hatching success and juvenile mortality (wolda 1970, yom-tov 1972, ooSterhoff 1977, reichardt et al 1985, lazaridou-dimitriadou et al 1998, ligaSzewSKi et al 2007. It is possible that the density of land snail populations may be regulated through growth rate, adult size and fecundity.…”

Mechanisms which govern patterns of intra-specific vatiation in land snails were traced within areas of different size, using Brephulopsis cylindrica (Menke), Chondrula tridens (O. F. Müller), Xeropicta derbentina (Krynicki), X. krynickii (Krynicki), Cepaea vindobonensis (Férussac) and Helix albescens Rossmässler as examples. Morphometric shell variation, colour and banding pattern polymorphism as well as genetic polymorphism (allozymes and RAPD markers) were studied. The results and literature data were analysed in an attempt to link patterns to processes, with the following conclusions. Formation of patterns of intraspecific variation (initial processes of microevolution) takes different course at three different spatial scales. At micro-geographical scale the dominant role is played by eco-demographic characteristics of the species in the context of fluctuating environmental factors. At meso-geographical scale a special part is played by stochastic population-genetic processes. At macro-geographical scale more or less distinct clinal patterns are associated with basic macroclimatic indices, while the stochastic processes tend to lose importance. The basic factors of microevolutionary process which act at different spatial scales result from processes which progress over different lengths of time: micro-geographical variation patterns reflect processes which are in progress at the moment; meso-geographical variation is to a larger extent determined by processes which occurred in historic past; macro-geographical variation reflects processes which coincided with formation of the respective landscapes or climate zones.
