AbstractConceptions in mammals may depend on a variety of factors including mate familiarity, age, sociosexual experience and female mate choice. We tested predictions for the effects of these factors on pregnancies in a captive colony of grey mouse lemurs (Microcebus murinus). The succession of oestrous cycles and pregnancies was analysed for a total of 26 different females that were housed together with 33 different males over a total of 124 oestrous cycles between 1995 and 2001. In addition, sexual behaviours were recorded and analysed over 13 oestrous cycles of 9 different females. An effect of mate familiarity on pregnancies could be detected by a frequent delay of pregnancies to the second cycle of the season (66.7% of the possible cases). Female age influenced pregnancies as the 2-3-year old females were less likely to become pregnant than females of other age classes. This reduced rate of pregnancies, however, was probably due to the lack of previous sociosexual experience with males. Females that have not been housed with males within their first reproductive season, needed one or two years of sociosexual experience before their first successful impregnation. These findings are discussed as a side effect of the ontogenetic development of female dominance. Female mate choice could be deduced from the succession of pregnancies and the strong responsibility of the females for the termination of matings.

Abstract In haplodiploid species, daughter production, but not son production, is sexual, requiring paternal contributions. Females may use male signals to choose a mate with better daughter-production potential, if the choice facilitates her production of adaptive sex ratios, e.g., female-biased sex ratios in systems operating under local mate competition (LMC). In the parasitoid wasp Urolepis rufipes, females preferred pheromone markings from males that had mated once versus multiply, were young rather than old, and were uninfected rather than infected when infection was low, but not when infection was high. Mates of singly-mated males had more female-biased offspring sex ratios than those of multiply-mated males, whereas there was no difference for mates of young versus old males. Thus, female preference for singly-mated males appears to provide indirect fitness benefits. A preference for young males, was not beneficial in the laboratory, but in nature young males may have mated less.

Abstract The Iberian wall lizard Podarcis hispanica forms part of a species complex with several morphologically and genetically distinct types and populations, which may or may not be reproductively isolated. We analyzed whether female mate choice based on males’ chemical signals may contribute to a current pre-mating reproductive isolation between two distinct populations of P. hispanica from central Spain. We experimentally examined whether females choose to establish territories on areas scent-marked by males of their own population, versus areas marked by males of the other population. Results showed that females did not prefer scent-marks of males from their own population. In contrast, females seemed to attend mostly to among-individual variation in males’ pheromones that did not differ between populations. Finally, to test for strong premating reproductive isolation, we staged intersexual encounters between males and females. The population of origin of males and females did not affect the probability nor the duration of copulations. We suggest that the different environmental conditions in each population might be selecting for different morphologies and different chemical signals of males that maximize efficiency of communication in each environment. However, females in both populations based mate choice on a similar condition-dependent signal of males. Thus, male signals and female mate choice criteria could be precluding premating reproductive isolation between these phenotypically “distinct” populations.
