Sex and conflict in simultaneous hermaphrodites

In animal species that mate promiscuously, store sperm and fertilise internally, the sperm from two or more donors usually compete for access to eggs. Such sperm competition often leads to sexual conflict, because traits that are advantageous to the sperm donor can be harmful to the recipient. There are many studies investigating how an individual can manipulate its mating partner to its own benefit, but most of these are restricted to species with separate sexes.

One famous example from hermaphroditic animals is the bizarre act of dart shooting in land snails. In many species, a so-called "love dart" is forcefully stabbed through the skin of the mating partner. In Cornu aspersum (previously Helix aspersa) this results in the injection of an allohormone that increases sperm storage and paternity, probably via a decrease in sperm digestion. This project aims at investigating the darts shape, function and use within as well as between species of different families of land snails. Within species nothing is currently known about, for example, the diversity in dart shapes between individuals from different populations. Between species there is a large diversity in dart shapes and numbers and on top of that these darts are stabbed in very different ways. In addition, in none of these species has it been established whether the dart has a similar effect on the recipient as the demonstrated effect in C. aspersum. All this information about darts and dart shooting within and between species is essential for a full understanding of the evolution of this odd reproductive act.
