“…Although some terrestrial gastropods mate randomly with respect to shell size (Wolda 1963;Baur 1992), there is substantial evidence that body size affects mating patterns in several marine gastropods (Crozier 1918;Edwards 1968;Staub & Ribi 1995;Angeloni & Bradbury 1999;Johnson 1999;Pal et al 2006;Zahradnik et al 2008).

“…The evidence for size-assortative mating in simultaneous hermaphrodites remains ambiguous: some studies found positive relationships between partner body sizes in field and laboratory populations of molluscs (Tomiyama 1996;Yusa 1996;Angeloni & Bradbury 1999;Angeloni 2003;Angeloni et al 2003;Pal et al 2006), but most of these correlations were rather weak. Several other studies failed to detect any mating patterns that are consistent with size-assortative mating (reviewed in Chaine & Angeloni 2005;Koene et al 2007).…”

Body size is expected to affect the mating behaviour and mating patterns of simultaneous hermaphrodites, because it can influence fecundity, mate choice and mechanical constraints to mating. However, there is a lack of detailed research on size‐dependent mating patterns in hermaphroditic species, including aquatic pulmonates. We investigated mating patterns and mating success in the simultaneous hermaphroditic pond snail Radix lagotis (Gastropoda: Pulmonata). We found that fecundity increased with body size and we observed a strong pattern of size‐assortative mating across two breeding seasons. Sperm donors were more likely to inseminate large snails than small snails, and pairings between two large individuals were more likely to result in successful copulations than pairings of two small individuals or two individuals of differing sizes. Other possible explanations (mechanical constraint) for these patterns are also discussed.

“…Thus, when mating with a larger animal, more resources should be diverted to sperm transfer than when mating with a small animal (Angeloni et al, 2002;Jordaens et al, 2007). Empirical studies provide ample evidence for the existence of size-dependent mating (DeWitt, 1996;Yusa, 1996;Angeloni et al, 2002;Ohbayashi-Hodoki et al, 2004;Chaine and Angeloni, 2005;Pal et al, 2006;Jordaens et al, 2007) but also non size-dependent mating strategies in hermaphrodite gastropods species (Switzer-Dunlap et al, 1984;Baur, 1992;. It is conceivable, however, that interpretation of some these studies is confounded by the fact that, for many of the species used, size is a covariant of age.…”

SUMMARYIn many mating systems female reproductive capacity is a limiting resource over which males will compete. As a consequence, males and females have usually different fitness optimization strategies which may give rise to sexual conflict. Since simultaneous hermaphrodites have, in theory, the option to mate as male or as female at any time, conflict will occur if partners insist in taking the same role. Several lines of evidence exists that body size influences gender choice. However, growth in many invertebrates is indeterminate and therefore age is generally a covariant of size. We therefore investigated the effect of age on mating choices in the simultaneous hermaphrodite Lymnaea stagnalis. Using fully sexually mature animals sampled from three different age groups we show that copulation frequency declines with age. Specifically, in age-matched couples the frequency of primary and reciprocal copulations declines with age. Furthermore, the younger partner tends to mate as male with greater probability in couples of unequal age. Size was never a factor in the sex role preference of Lymnaea. Thus, young Lymnaea always attempt to copulate as male independent of the age of their partner, whereas senior snails act primarily as female. The sex role choices of middle-aged snails appear to depend on their partnerʼs age. In addition, we demonstrate that the likelihood that an animal will copulate as male is not correlated with prostate gland size but correlates with the level of afferent electrical activity recorded in the nerve originating in the prostate gland. Together, our results indicate the existence of an age-and not sizedependent mating system in Lymnaea.

“…Mating patterns are known only for Siphonaria capensis which gives or receives sperm, but not both, in a single mating (non-reciprocal copulation, Pal et al 2006). In Panama, Levings and Garrity (1986) found that S. gigas mate most often (59/86 cases, 68 %) with their nearest neighbors which typically are so close that their shells touch.…”

“…Size-assortative mating has been described for S. capensis and has been ascribed primarily to the association of limpets of similar size at small spatial scales with a lesser contribution of mate choice and mating constraints among available local partners (Pal et al 2006). Each of these processes could contribute to the formation of pairs of similar size in S. gigas as well.…”
