摘要：

A comparison was made of the evolutionary patterns among the larviparous and oviparous species of the family Ostreidae. The data reveal that larviparous species have experienced a wider range of environmental variables, life history traits, and levels of genetic variation than have oviparous species. Non-parametric correlation coefficients were obtained among fifteen variables (i.e., two genetic, four environmental and nine life-history variables). Among the life-history variables, mode of larval development, fecundity, egg size, initial size of the planktonic larva and planktonic larval period were found to covary significantly with the genetic variables. In a comparison of environmental and life-history variables, the mode of larval development and habitat water depth were found to covary. The implications of these results are discussed with reference to the evolution of the family Ostreidae.
