Females of highly iteroparous, oviparous species must mate multiply and potentially choose mates hundreds to thousands of times throughout their lifespan. Theory indicates that costly female mating preferences may favor low levels of preference in species that have to mate repeatedly. One potential cost of mating preference is overripening, which occurs in some external fertilizers when females ovulate but do not spawn their eggs. Overripening may create a trade-off between the benefits of mate choice (i.e., rejecting males of poor quality) and egg viability. This study tested for overripening as a cost of delayed mating and determined its effects on female mating preferences in the bluefin killifish, Lucania goodei. Female L. goodei often mate multiple times each day across multiple days when gravid. Females were divided into three treatments: mate every day, mate every two days, and mate every four days. In the first experiment, females were paired with either a red or a yellow conspe..., We collected bluefin and rainwater killifish. We conducted two experiments. In the first, females were allowed to mate daily, every other day, or once every four days. The goal was to determine whether egg viability decreased when females were precluded from spawning daily. We also sought to determine whether decreases in egg viability due to overripening caused a decrease in female mating preference. In the first experiment, female L. goodei could spawn with either a red or yellow color morph of their own species. Females were paired either every day, every other day, or once every four days with either a red or yellow male and given the opportunity to spawn for four hours. After this time, the eggs were collected, counted, and their survival to hatching was recorded. In the second experiment, female L. goodei were allowed to spawn with either a conspecific L. goodei male or a heterospecific L. parva male. Again, on spawning days, females could spawn ..., , # Costs of delayed mating opportunities, overripening, and mate choice in Killifish
