“…Overall, this study indicates that the cost of remating increases with the number of rematings, and that remating can be costly to females in the currency of net fitness, and in the context of a short-lifespan demography. We have also shown that the cost of remating can be manifest in the currency of reduced daily fecundity, rather than the reduced survival that has been found in previous studies (Partridge et al, 1986(Partridge et al, , 1987Fowler & Partridge, 1989;Partridge & Fowler, 1990;Trevitt & Partridge, 1991;Chapman, 1992;Chapman et al, 1993Chapman et al, , 1994Chapman et al, , 1995, and we have quantified the accelerating cost of each additional remating. Lastly, we agree with Cordero & Eberhard (2003) that it is impossible to directly extrapolate findings from laboratory populations to wild populations, because of the large differences in environmental conditions.…”

“…One potential complication with the use of the LH M base population is the previous finding, albeit in a different population, that most male‐induced harm to females is attributable only to reductions in their long‐term adult survival (Partridge et al. , 1986, 1987; Fowler & Partridge, 1989; Partridge & Fowler, 1990; Trevitt & Partridge, 1991; Chapman, 1992; Chapman et al. , 1993, 1994, 1995) – a trait that would not be manifest in our short‐lived LH M base population.…”

“…At present, the first approach cannot be feasibly accomplished, at least with the technology currently available. Here we use the second approach by extending prior work of L. Partridge, K.

The cost of mating rises nonlinearly with copulation frequency in a laboratory population of Drosophila melanogaster

Previous studies of Drosophila melanogaster have demonstrated a cost to females from male courtship and mating, but two critically important parameters remain unresolved: (i) the degree to which harm from multiple‐mating reduces lifetime fitness and (ii) how harm from mating might change with successive matings (rematings). Here we use ‘laboratory island analysis’ to quantify the costs that females incur with each remating, in the currency of lifetime fitness and under conditions that closely match those to which the flies have adapted for hundreds of generations. We experimentally manipulated the number of female matings by varying the order of daily 2‐h exposures of females to either sperm‐less males (XO) or intact males (XY). Females that mated more often had substantially reduced lifetime fecundity, and importantly, the fitness cost from remating rapidly accelerated.

“…In the case of fruit flies, lab strains are typically kept in 2‐week culture, where adults are allowed to lay eggs on fresh medium for 1–2 days and then are discarded at the age of 5–7 days. Two‐week culture selects for high early fecundity and, at least in lab populations, fecundity is strongly negatively correlated with survival (Fowler & Partridge, 1989; Trevitt & Partridge, 1991; Chapman et al ., 1993; Cordts & Partridge, 1996; Prowse & Partridge, 1997; Sgro & Partridge, 2000). At the same time that lab culture increases selection on early fecundity, it dramatically reduces the strength of selection to remove deleterious genes expressed later than about 7 days (Promislow & Tatar, 1998).…”

Testing an ‘aging gene’ in long‐lived Drosophila strains: increased longevity depends on sex and genetic background

SummaryMolecular advances of the past decade have led to the discovery of a myriad of 'aging genes' ( methuselah , Indy , InR , Chico , superoxide dismutase ) that extend Drosophila lifespan by up to 85%. Despite this life extension, these mutants are no longer lived than at least some recently wildcaught strains. Typically, long-lived mutants are identified in relatively short-lived genetic backgrounds, and their effects are rarely tested in genetic backgrounds other than the one in which they were isolated or derived. However, the mutant's high-longevity phenotype may be dependent on interactions with alleles that are common in short-lived laboratory strains. Here we set out to determine whether one particular mutant could extend lifespan in long-lived genetic backgrounds in the fruit fly, Drosophila melanogaster . We measured longevity and resistance to thermal stress in flies that were transgenically altered to overexpress human superoxide dismutase ( SOD ) in the motorneurones in each of 10 genotypes. Each genotype carried the genetic background from a different naturally long-lived wild-caught Drosophila strain. While SOD increased lifespan on average, the effect was genotypeand sex-specific. Our results indicate that naturally segregating genes interact epistatically with the aging gene superoxide dismutase to modify its ability to extend longevity. This study points to the need to identify mutants that increase longevity not only in the lab strain of origin but also in naturally long-lived genetic backgrounds.

“…Moreover, the seminal fluid injected by a male affects, often negatively, the fitness of the inseminated female and also the proclivity of the female to mate again. A sort of tug-of-war between the sexes occurs, because the fitness interests of males and females are partly at odds (3)(4)(5)(6)(7)(8)(9)(10)(11).…”

Male mating success is an important fitness component in Drosophila. The seminal fluid conveyed with the sperm inhibits the proclivity of the female to remate and reduces her fitness. Nevertheless, females may remate before they have exhausted the sperm from the first male and consequently use sperm from both males. We have studied concurrent multiple paternity (CMP) in two Drosophila melanogaster populations, from an apple orchard and a vineyard just after harvest. CMP is high in both populations, somewhat greater than 50%; but it is not significantly higher in the vineyard, where the population density is much greater than in the orchard. Population density had been thought to be an important determinant of CMP incidence. We have used four gene loci coding for enzymes as independent markers for detecting CMP.
