【 摘 要 】

ABSTRACT: For many biological resources, larger males are more likely to be harvested than smaller ones. In such harvested populations, the remaining males are relatively small and participate in more matings than in pristine populations. Because the number of sperm passed to females generally decreases with decreasing male body size and increasing male mating frequency, the reproductive success of females in populations subjected to such harvesting patterns can be restricted due to sperm limitation. The Japanese population of the coconut crab
