摘　　要：Assessing the determinants of reproductive success is critical but often complicated because of complex interactions between parental traits and environmental conditions occurring during several stages of a reproductive event.Here,we used a simplified ecological situation-an amphibian species lacking post-oviposition parental care-and a laboratory approach to investigate the relationships between parental(both maternal and paternal)phenotypes(body size and condition)and reproductive success(fecundity,egg size,embryonic and larval duration,larval and metamorphic morphology).We found significant effects of maternal phenotype on fecundity,hatching success,and tadpole size,as well as on the duration of larval development.Interestingly,and more surprisingly,we also found a potential contribution of the paternal phenotype occurring during early(embryonic development duration)offspring development.Although our study focused on life-history traits such as body size and development duration,additional mechanisms involving physiological costs of development may well mediate the relationships between parental phenotypes and offspring development.Future studies are required to decipher the mechanisms underlying our findings in order to clarify the mechanistic basis of the links between parental phenotypes and offspring development.
