“…There is, however, evidence of a cost to mating in that mating appears to reduce longevity (Pitafi, 1991;Gilburn & Day, in preparation). A similar relationship has been found in Drosophila melanogaster (Partridge et at., 1987;Fowler & Partridge, 1989). There may also be an energy cost associated with rejecting males, particularly large ones.…”

“…It is therefore paid only by RR females and results in a proportion, m, of females failing to produce progeny. As in other insect species (Partridge et al, 1987;Fowler & Partridge, 1989;Rowe et a!., 1994), mating in seaweed flies carries a cost; Pitafi (1991) found that females allowed unlimited matings died younger than did virgin females. Furthermore, a positive correlation exists between the frequency of rejection and female longevity (Gilburn & Day, in preparation).…”

The evolution of female choice when the preference and the preferred trait are linked to the same inversion system

This study reports results of computer simulations of the evolution of female mating preferences when both the preference and the preferred character are associated with the same chromosomal inversion system. When there is strong heterosis associated with the inversion system and no direct selection acting on mating preferences, a pattern of disassortative mating with respect to the inversion is predicted to evolve. Females mating disassortatively produce highly fit heterokaryotypic offspring. However, when heterosis is weak, Fisherian sexual selection can maintain strong assortative preferences, but the inversion polymorphism is lost. Assortative preferences are only likely to be maintained in conjunction with a polymorphic inversion system if direct sexual selection is operating. The results of this study are discussed with respect to the seaweed fly, Coelopa frigida, in which the preference and preferred trait are associated with the ocfl inversion system.

“…Conversely, an experimental increase in diet quality in field crickets, Teleogryllus commodus, resulted in reduced male longevity but increased reproductive effort (Hunt et al, 2004). Similar trade-offs have been found in other taxa: when reproduction is experimentally limited, survival often increases (Partridge et al, 1987;Tatar et al, 1993;Ellers et al, 2000;Hosken, 2001;McKean and Nunney, 2001). Although our study does not provide direct evidence of a trade-off between fecundity and immunity, previous measurements on the same inbred lines and outbred population of G. sigillatus have demonstrated that inbred individuals have lower reproductive investment than outbred colony individuals (St John JM and Sakaluk SK, unpublished data).…”

Inbred decorated crickets exhibit higher measures of macroparasitic immunity than outbred individuals

Inbreeding is assumed to have negative effects on fitness, including the reduced ability to withstand immune challenges. We examined the immunological consequences of inbreeding in decorated crickets, Gryllodes sigillatus, by comparing lytic activity, phenoloxidase (PO) activity, and encapsulation ability of crickets from eight inbred lines with that of crickets from the outbred founder population. Surprisingly, crickets from inbred lines had a greater encapsulation ability compared with crickets from the outbred population. We suggest that because inbred crickets have reduced reproductive effort, they may, therefore, have the option of devoting more resources to this form of immunity than outbred individuals. We also found that both inbred and outbred females had higher immunity than males in PO activity and implant darkness. This result supports the hypothesis that females should devote more effort to somatic maintenance and immunity than males. PO activity and implant darkness were heritable in both males and females, but lytic activity was only heritable in females. Males and females differed in the heritability of, and genetic correlations among, immune traits, suggesting that differences in selective pressures on males and females may have resulted in a sexual conflict over optimal immune trait values.

“…Here we found that males among species usually differed in both intercepts and slopes, whereas females differed primarily in the slope, or rate of aging. This contrast among sexes may reflect how costs of reproduction have evolved in females relative to males (Partridge et al ., 1987). Future studies will be needed to address this question more directly.…”

Age‐specific metabolic rates and mortality rates in the genusDrosophila

SummaryEarly theories of aging suggested that organisms with relatively high metabolic rates would live shorter lives. Despite widespread tests of this 'rate of living' theory of aging, there is little empirical evidence to support the idea. A more fine-grained approach that examined age-related changes in metabolic rate over the life span could provide valuable insight into the relationship between metabolic rate and aging. Here we compare age-related metabolic rate (measured as CO 2 production per hour) and age-related mortality rate among five species in the genus Drosophila . We find no evidence that longer-lived species have lower metabolic rates. In all five species, there is no clear evidence of an age-related metabolic decline. Metabolic rates are strikingly constant throughout the life course, with the exception of females of D. hydei , in which metabolic rates show an increase over the first third of the life span and then decline. We argue that some physiological traits may have been shaped by such strong selection over evolutionary time that they are relatively resistant to the decline in the force of selection that occurs within the life time of a single individual. We suggest that comparisons of specific traits that do not show signs of aging with those traits that do decline with age could provide insight into the aging process.
