Determinants of paternity in the garden snail Helix aspersa
Abstract. Despite the likely importance of post-copulatory sexual selection in simultaneous hermaphrodites, the factors influencing sperm competition in these organisms are generally unknown. We haveExpand

Dart receipt promotes sperm storage in the garden snail Helix aspersa
Abstract. During courtship, many helicid snails attempt to pierce the body walls of their mating partners with mucus-coated calcareous darts. The mucus covering the dart induces conformationalExpand
