Abstract
A survey of the available molluscan literature shows that reproductive effort is higher in semelparous species (29.90%) than in iteroparous species (18.21%), and that in iteroparous species reproductive effort increases with successive breeding seasons. Oviparous species were found to divert considerably more into reproduction than viviparous species, with 24.24% and 5.25% channeled respectively.
摘要
对现有软体动物文献的一项调查表明，一次性繁殖物种的繁殖投入（29.90%）高于多次繁殖物种（18.21%），并且在多次繁殖物种中，繁殖投入会随着连续繁殖季节而增加。研究发现，卵生物种用于繁殖的投入比胎生物种多得多，分别为24.24%和5.25%。
