Introduction
Marine habitats tend to subject organisms to unique selective pressures that are reflected in the life-history strategies that evolve in this environment (Hendler, 1975; Strathmann et al., 1984; McEdward and Coulter, 1987; Emlet et al., 1987; Strathmann, 1990). For free-spawning marine invertebrates, fertilization via the release of sperm into the water column may lead to distinctive selective pressures on life-history strategies (Ghiselin, 1987; Strathmann, 1990). In particular, recent field experiments and assays of fertilization success in nature have suggested that selection via fertilization processes may profoundly influence both the quantity of ...
