“…In the treatment phase, all snails were ranked according to size and allocated to either an isolated treatment or a paired treatment, ensuring each treatment had a similar range in body size. The pairs were matched according to size (±1 mm), thereby removing size effect between partners (Nakadera, Swart, Maas, et al, ). As above, the standardization period was followed by a treatment week, during which time all egg masses laid by isolated and paired snails were collected twice to determine treatment effect on egg laying (Figure ).…”

Sexual conflicts often arise between mating partners because each sex tries to maximize its own reproductive success. One major male strategy to influence a partner's resource allocation is the transfer of accessory gland proteins. This has been shown to occur in simultaneous hermaphrodites as well as in organisms with separate sexes. Although accessory gland proteins affect the investment of resources in both male and female function, we here specifically focus on female investment. In the great pond snail, Lymnaea stagnalis, previous studies found that the accessory gland protein ovipostatin reduced female fecundity by suppressing egg laying in the partner in the short term (days). To investigate whether this reduction in egg laying is a commonly found effect of mating in freshwater snails, we compared egg output for evidence of suppression in isolated and paired snails of eight pulmonate species. Furthermore, we determined whether the suppression of egg laying caused a shift in resource allocation to the eggs. We found that in five of the eight species egg laying was suppressed, with fewer and lighter egg masses being laid when they had access to a mating partner. In mated pairs of L. stagnalis and Biomphalaria alexandrina, allocation of resources to the eggs was altered in opposite ways: individuals of L. stagnalis laid fewer but larger and heavier eggs; individuals of B. alexandrina laid smaller and lighter eggs, with no change in egg numbers. Such changes in the female function are most likely the result of combined effects of receiving accessory gland proteins, and the cost of mating in both male and female roles. Thus, effects of the maternal environment, including the receipt of accessory gland proteins, on offspring investment are not restricted to species with separate sexes.

“…1). The effect of body size on role selection is well documented in simultaneous hermaphrodites (see Table 2 in Chaine and Angeloni, 2005; (Dillen et al , 2008; Dillen et al , 2010; Nakadera et al , 2015); however, the relationship has not been strongly supported in A. californica (Zaferes et al , 1988; Pennings, 1991; Angeloni et al , 2003). Nevertheless, potential mates were selected so that the percent difference in mean body mass between them did not exceed 30%; otherwise, pairs were established by random selection.…”

In simultaneous hermaphrodites, a clear conflict exists between sperm donor and sperm recipient roles; however, how such conflict is mediated remains up for debate. This study recorded and observed mating role selection as a function of resource availability in the simultaneous hermaphrodite, Aplysia californica. When food was plentiful animals participated in both sperm donor and recipient roles at relatively even frequency. However, when half of the mating pairs were placed on restricted diets, food limited animals participated in the sperm donor role at a significantly (p<0.05) greater frequency than their ad libitum partners; however, the frequency of total successful mating events remained the same. The mass and frequency of eggs laid were also significantly (p<0.05) correlated with parental food intake. These results demonstrate how mating strategies can change relatively quickly as a result of shifting environmental conditions and calls for a diverse framework to address these issues in simultaneous hermaphroditic mating systems.

“…We therefore urge further studies on the topic, especially at the population level and/or in natural conditions, to complement the current detailed knowledge of cell-, molecular-, and organismal-level of the reproductive biology and behaviour of L stagnalis (e.g. ter maat et al 1989, 2007, Janse et al 1990, hermann et al 1997, Koene 2010, naKadera et al 2015.…”

A note on oviposition by Lymnaea stagnalis (Linnaeus, 1758) (Gastropoda: Pulmonata: Lymnaeidae) on shells of conspecifics under laboratory conditions

Oviposition by Lymnaea stagnalis (L.) on shells of conspecifics has been reported anecdotally from laboratory observations. In order to gain the first quantitative insight into this behaviour, we have quantified the proportion of individuals bearing egg clutches in a long-term monospecific outdoor laboratory culture of L. stagnalis during two consecutive late-summer months. The snails were assigned to size classes based on shell height. Differences between the size class composition of clutch-bearers and of the general population were statistically compared by means of Pearson's distance χ² P analysis. Egg clutches were laid on snails of shell height >15 mm (i.e. reproductive-age individuals), with significant selection for the larger size classes (shell height 25-40 mm). While the mechanisms of and reasons behind such behaviour remain unknown, selection of larger adults as egg-carriers may have ecological implications at the population level.
