Strategic sperm allocation and a Coolidge effect in an externally fertilizing species

Original language description

Because sperm is costly and limiting, males are predicted to allocate sperm differentially across matings, according to the level of sperm competition, female reproductive quality, and female novelty. We investigated sperm allocation in the European bitterling (Rhodeus amarus), an externally fertilizing species of fish that spawns and incubates its eggs in the gills of freshwater mussels. We predicted that males would allocate sperm differentially according to the quality and novelty of mussels. Dominant males responded to rivals by increasing both sperm investment and aggression, whereas subordinates responded chiefly through sperm investment. Dominant males invested more sperm in novel mussels in accordance with predictions for a Coolidge effect, themussel representing a new fertilization opportunity. However, subordinate males were not influenced by mussel novelty but were responsive to order of mating. Males did not allocate sperm according to mussel quality, suggesting that certa
