It has been proposed that size-assortative mating should occur in simultaneous hermaphrodites with reciprocal fertilization and size-related fecundity because all individuals invest substantially in mating. Mating patterns were recorded in two species of simultaneously hermaphroditic land snails. In a natural population of Helix pomatia, snails showed a slight (but non-significant) tendency towards size- assortative mating, whereas mating in a population ofA rianta arbustorum was random with… CONTINUE READING
