Abstract

Female common wall lizards (Podarcis muralis) typically reproduce annually and lay more than one clutch per season. In this study, we tested whether females store sperm between clutches and between years by manipulating mating opportunities of females through appropriate experiments. Our results revealed that females are definitely unable to store sperm for medium or long-term, suggesting they necessary need to repeatedly mate with males to fertilize their eggs. Finally, by comparing our results to other similar multi-clutched species, we conclude that sperm storage probably does not constitute a selective advantage for species with a promiscuous reproductive system based on multiple mating in populations with high densities.
