“…Beetles from L lines live more than twice as long as those from E lines (Đorđević et al. ). Our results show that the activities of ETC complex I, II, and especially III were higher in beetles from L lines.…”

“…The MN lines studied here were also, in an accompanying study (Đorđević et al. ), characterized with respect to major life‐history traits (i.e., sex‐specific development time, body mass, and longevity). Here, we used this opportunity to ask whether, across MN lines, sex‐specific mitochondrial ETC activity predicted major life‐history traits (data in Tables S1 and S2).…”

“…For example, beetles from L lines live more than twice as long and senesce half as rapidly as do those from E lines (Đorđević et al. ). Importantly, we show in an accompanying study that the L selection lines are now largely fixed for a particular mtDNA haplotype, whereas the E lines are all polymorphic for two other mtDNA haplotypes, by and of itself suggesting a role for mtDNA in the divergent evolution observed (Stojković et al.…”

The role of mitochondrial DNA for the evolution of life-history traits remains debated. We examined mitonuclear effects on the activity of the multisubunit complex of the electron transport chain (ETC) involved in oxidative phosphorylation (OXPHOS) across lines of the seed beetle Acanthoscelides obtectus selected for a short (E) or a long (L) life for more than >160 generations. We constructed and phenotyped mitonuclear introgression lines, which allowed us to assess the independent effects of the evolutionary history of the nuclear and the mitochondrial genome. The nuclear genome was responsible for the largest share of divergence seen in ageing. However, the mitochondrial genome also had sizeable effects, which were sex-specific and expressed primarily as epistatic interactions with the nuclear genome. The effects of mitonuclear disruption were largely consistent with mitonuclear coadaptation. Variation in ETC activity explained a large proportion of variance in ageing and life-history traits and this multivariate relationship differed somewhat between the sexes. In conclusion, mitonuclear epistasis has played an important role in the laboratory evolution of ETC complex activity, ageing, and life histories and these are closely associated. The mitonuclear architecture of evolved differences in life-history traits and mitochondrial bioenergetics was sex-specific.

“…Markedly depressed MR early in adult life was associated with the evolution documented in previous studies of these beetles, i.e. that of longer juvenile development time, larger body size, depressed reproductive effort early in life, prolonged life span and a decreased rate of senescence (see Đorđević et al., ; Stojković & Savković, ; Tucić et al., , , ). Overall, MR was 18% higher early in life in E lines compared to L lines.…”

“…These lines have been selected for >160 generations for reproduction early (E) or late (L) in adult life (Tucić, Stojković, Gliksman, Milanović, & Šešlija, ; Tucić et al., ) and now show dramatic differences in life‐history traits. Most importantly, L line beetles live much longer: the average life span of virgin females is 10.3 days in E lines (rate of senescence = 0.65), 25.6 days in L lines (rate of senescence = 0.23) and 14.6 days in the base population (Đorđević, Savković, Lazarević, Tucić, & Stojković, ; Stojković & Savković, ; Stojković, Šešlija Jovanović, Tucić, & Tucić, ). Further, E line beetles show a more rapid egg‐adult development time and are smaller than beetles from the L lines.…”

The pace‐of‐life: A sex‐specific link between metabolic rate and life history in bean beetles

Metabolic rate (MR) is a key functional trait simply because metabolism converts resources into population growth rate. Yet, our empirical understanding of the sources of within species variation in MR, as well as of its life history and ecological correlates, is rather limited. Here, we assess whether MR lies at the root of a syndrome of correlated rate‐dependent life‐history traits in an insect. Selection for early (E) or late (L) age‐at‐reproduction for >160 generations in the bean beetle Acanthoscelides obtectus has produced beetles that differ markedly in juvenile development, body size, fecundity schedules, ageing and life span. Here, we use micro‐respirometry to test whether this has been associated with the evolution of age‐ and sex‐specific metabolic phenotypes. We find that mass‐specific MR is 18% higher in E lines compared to L lines and that MR decreases more rapidly with chronological, but not biological, age in E lines. Males, under sexual selection to “live‐fast‐die‐young”, show 50% higher MR than females and MR decreased more rapidly with age in males. Our results are consistent with a central role for MR for the divergence in “pace‐of‐life” seen in these beetles, supporting the view that MR lies at the root of ecologically relevant life‐history trait variation within species.

The trade-off between lifespan and reproduction is central to our understanding of life-history evolution.Laboratory selection experiments have been a powerful tool for quantifying this trade-off, but these tend to be restricted in taxonomic scope, which may limit our understanding. In addition, research often focuses on the trade-off between lifespan and reproductive effort in females, and far less data test how lifespan trades-off with different aspects of male reproduction (e.g., pre-and post-copulatory reproductive investment). Here we examined the trade-off between lifespan and reproduction in females and males of the marula fruit fly, Ceratitis cosyra, (Walker) (Diptera: Tephritidae). To do so, we selected downward or upward on age of peak female egg laying in C. cosyra for twenty generations. In multiple generations, we measured female and male lifespan and body size, female daily and lifetime fecundity, male courtship and mating success, as well as the number of sperm transferred at different ages and sperm storage asymmetry in spermathecae. Our selection regime appeared to achieve its aim; egg laying peaked earlier in females from downward selected lines than upward selected lines. The number of sperm transferred by males decreased in the upward selected flies, but other male reproductive traits remained the same across selection regimes. In contrast, with the wider literature, upward-selection did not extend the lifespan of females or males after ten generations of selection.While lifespan in both sexes responded to selection on female egg laying schedules, it did not do so in a straightforward way. Moreover, male investment in reproductive traits was largely independent of selection regime. These counter-intuitive findings highlight the importance of working with a broad range of species and of considering the trade-off between reproduction and lifespan in both sexes. Significance statementThe trade-off between lifespan and reproduction has been extensively studied in model species using various types of laboratory selection. A limited number of species have been considered using this approach, and the majority of the studies have focused on female, rather than male, reproductive effort.Here, we selected downwards and upwards on age of female reproduction in the marula fruit fly and measured survival, female fecundity, reproductive schedule, as well as male sperm transfer, sperm 4 storage asymmetry, mating and calling success. We found a moderate trade-off between lifespan and early fecundity in downward selected flies, whereas no obvious trade-off was observed in upward selected lines. Regardless of the selection regime, reproductive scheduling was affected in females but not in males, while lifespan was affected in both sexes. Our results show that the timing of reproduction can evolve independently across the sexes, highlighting the importance of studying both females and males.
