The purpose of this research is to elucidate the                           relationship of male parental care and sexual selection in two                  species of midwife toads (alytes obstetricians and A.                           cisternasii,  Anura, Discoglossidae).  Evidence for partial or                  total sex role reversal will be sought through the                              quantification of intrasexual competition for mates and mate                    choice selectivity.                                                                  The project will involve 1) Monitoring of natural                          populations of marked individuals. 2) Laboratory analysis of                    caloric content to determine the relative energetic cost of                     reproduction in each sex. 3) Laboratory and field observations to               determine the intensity of intrasexual competition for mates in                 both sexes. 4) Laboratory and field experiments with synthesized                calls to determine selectivity based on acoustical communication.                    The comparison of the two species will constitute a unique                 test of the hypothesis which states that relative parental                      investment determines sex roles and hence determines which sex                  will be more subject to sexual selection.  The results obtained                 will permit the discrimination between the effect of male                       parental investment on sexual selection and on its outcome.
