“…Since females largely determine whether copulation occurs or not in Drosophila (Markow 1996), and there are significant costs to females from continuous exposure to male courtship (e.g. Partridge and Fowler 1990;Taylor et al 2008b), they are predicted to respond to preferred males more rapidly. The latency to copulation has been used as a standard measure of female preference across many Drosophila studies (see above).…”

Much of the recent work on the evolution of female choice has focused on the relative influence of direct and indirect benefits, and particularly whether direct costs can be offset by indirect benefits. Studies investigating whether attractive males benefit females by increasing the viability of their offspring often report mating advantages to sons consistent with the Fisher process, while detecting no or weak viability benefits. One potential reason for this is that sons may trade-off viability benefits with investment in costly traits that enhance mating success, leading to the suggestion that viability benefits may be better detected by examining daughters' fitness. Here we investigate the relationship between male attractiveness and daughters' fitness in Drosophila simulans. We measured daughter (and dam) lifetime reproductive success and longevity. We found no evidence that attractive males sire high fitness daughters. Additionally, neither daughters nor dams gained direct benefits from mating with attractive males. However, aspects of daughters' fitness were related to dam characters.

Theory predicts that in monandrous butterfly species males should not invest in a long lifespan because receptive females quickly disappear from the mating population. In polyandrous species, however, it pays for males to invest in longevity, which increases the number of mating opportunities and thus reproductive fitness. We tested an extension of this idea and compared male and female lifespan of two closely related Yponomeuta species with different degree of polyandry. Our results confirmed the theoretical prediction that male lifespan is fine-tuned to female receptive lifespan; once-mated males and females of both polyandrous species had an equal lifespan. However, the degree of polyandry was not reflected in male relative to female lifespan. The observed similar female and male lifespan could largely be attributed to a dramatic reduction of female lifespan after mating.

“…However, such experiments may simultaneously alter other lifehistory traits such as female fecundity or offspring survival (e.g., Fox 1993;Fedorka and Mousseau 2002;Fisher et al 2006;Taylor et al 2008), thereby directly altering sibship structures and relationship frequencies. Furthermore, distributions of relationships and relatedness all depend on population size and dispersal rate, among-individual variation in survival and reproductive success, and variation in prereproductive mortality of offspring sired by different males (e.g., Fisher et al 2006;Gowaty et al 2010;Sardell et al 2011;Hsu et al 2014).…”

Online enhancements: supplemental PDF. Dryad data: http://dx.doi.org/10.5061/dryad.78568. abstract:The evolutionary benefits of simultaneous polyandry (female multiple mating within a single reproductive event) remain elusive. One potential benefit could arise if polyandry alters sibship structures and consequent relationships and relatedness among females' descendants, thereby intrinsically reducing future inbreeding risk (the indirect inbreeding avoidance hypothesis). However such effects have not been quantified in naturally complex mating systems that also encompass iteroparity, overlapping generations, sequential polyandry, and polygyny. We used long-term social and genetic pedigree data from song sparrows (Melospiza melodia) to quantify cross-generational consequences of simultaneous polyandry for offspring sibship structures and distributions of relationships and relatedness among possible mates. Simultaneous polyandry decreased full sibships and increased half-sibships, on average, but such effects varied among females and were smaller than would occur in the absence of sequential polyandry or polygyny. Further, while simultaneous polyandry decreased the overall frequencies of possible matings among adult full sibs, it increased the frequencies of possible matings among adult half-sibs and more distant relatives. These results imply that the intrinsic consequences of simultaneous polyandry for inbreeding risk could cause weak indirect selection on polyandry, but the magnitude and direction of such effects will depend on complex interactions with other mating system components and the form of inbreeding depression.
