“…In the case of very young mating partners, a number of studies have showed that the ability to mate successfully is no guarantee of full reproductive maturity. For example, in the male hide beetle Dermestes maculatus (Jones et al 2007) and both sexes of the common lizard Lacerta vivipara (Richard et al 2005), young individuals produce fewer and less viable offspring. Old mating partners, on the other hand, are less likely to be virgin, and thus perhaps more likely to be gamete-depleted or to carry sexually transmitted diseases.…”

The potential for sexual conflict to influence the evolution of life span and aging has been recognized for more than a decade, and recent work also suggests that variation in life span and aging can influence sexually antagonistic coevolution. However, empirical exploration of these ideas is only beginning. Here, we provide an overview of the ideas and evidence linking inter-and intralocus sexual conflicts with life span and aging. We aim to clarify the conceptual basis of this research program, examine the current state of knowledge, and suggest key questions for further investigation.S exual conflict arises because the sexes maximize their fitness via different, and often mutually incompatible, strategies, and its signature has been detected across a wide range of morphological, physiological, behavioral, and life-history traits in many species. A number of investigators have suggested that sexual conflict could play an important role in the evolution of two particularly interesting life-history traits: life span and aging (Svensson and Sheldon 1998;Promislow 2003;Bonduriansky et al. 2008;Maklakov and Lummaa 2013). Sexual conflict can affect life span and aging rate at both proximate (within-generation) and ultimate (evolutionary) scales. Sexually antagonistic behavioral or physiological interactions that increase mortality rate in one or both sexes (interlocus sexual conflict) could drive the evolution of faster life histories. Moreover, sex-specific optimization of reproductive strategies may often result in sex differences in life span and aging rates, and sexually antagonistic selection on shared genetic architecture can displace one or both sexes from their sex-specific optima for these traits (intralocus sexual conflict). Conversely, a change in life histories because of environmental fluctuations could affect the degree of sexual conflict in a population and influence sexual coevolution. Although evidence for sexual conflict is rapidly accumulating, our understanding of its relationship to life span and aging remains rudimentary. In this review, we provide a critical review of recent literature and highlight areas that require further investigation.

“…D. maculatus aggregates in groups of 1e13 adults on patchy resources for feeding and mating McNamara et al, 2004;Jones et al, 2006Jones et al, , 2007McNamara et al, 2008). Adults of D. maculatus are sexually dimorphic with females having a considerably larger size than males (Archer and Elgar, 1998).…”

“…Adults live 4e6 months under laboratory conditions (McNamara et al, 2004) and females can oviposit throughout that time (Woodcock et al, 2013).

“…Male fertilization success and sperm quality is largely unaffected over a male's lifetime (Hale et al, 2008), even when mating with multiple females (Jones et al, 2007), and males of an intermediate age (47 days after adult eclosion) have the highest rates of fertilization success (Jones et al, 2007). Males most often initiate mating but there is female choice , exerted with behaviors such as leaving the male or raising her abdomen to dislodge the male (McNamara et al, 2004).…”

“…Male ageing may have the potential to increase kin tolerance towards younger relatives. When old males are unable to fertilise all available eggs due to declining male fertility (Jones et al 2007;Møller et al 2009;Dean et al 2010), the relative cost of allowing a related male to mate (particularly in situations with no sperm competition, e.g. with a novel female) may be lower for old males compared to young males.…”
