AB  - Products and regulatory motifs of the mitochondrial and nuclear genomes
   interact closely to enable efficient cellular energy production within
   mitochondria. Although recent evidences support the prediction that
   during evolutionary time combinations of these interactions are
   optimized by selection acting on important life history traits,
   relatively few studies have directly tested it. The goal of this study
   was to test the role of mitonuclear interactions in shaping preadult and
   adult life history traits under age-specific selection in the seed
   beetle (Acanthoscelides obtectus). In order to disentangle the effects
   of mitochondria, nuclei and their interaction in the evolutionary
   response to the long-term laboratory selection for early (E) and late
   (L) reproduction, we used mitonuclear introgression lines in which E and
   L mitochondrial genomes were expressed in both E and L nuclear
   background. We found that mitonuclear genotypes carrying disrupted pair
   of nuclear and mitochondrial genomes mainly affected preadult life
   history traits-egg-to-adult viability and developmental time. Neither
   mitochondria nor their interaction with nuclear genomes had effects on
   realized fecundity of mated females and longevity of virgin beetles.
   However, when involved in reproductive activities females and males with
   disrupted genotypes mostly exhibited reduced longevity. Furthermore,
   since reproduced males exhibited greater longevity cost than females,
   our results are in accordance with the mother's curse hypothesis. Being
   that for the most life history traits we detected smaller additive
   mitochondrial genetic effects compared with epistatic mitonuclear
   effects, we concluded that mitonuclear interactions might be the target
   of age-specific selection.

AB  - We tested mutation accumulation hypothesis for the evolution of
   senescence using short-lived and long-lived populations of the
   seed-feeding beetle, Acanthoscelides obtectus (Say), obtained by
   selection on early-and late-life for many generations. The expected
   consequence of the mutation accumulation hypothesis is that in
   short-lived populations, where the force of natural selection is the
   strongest early in life, the late-life fitness traits should decline due
   to genetic drift which increases the frequency of mutations with
   deleterious effects in later adult stages. Since it is unlikely that
   identical deleterious mutations will increase in several independent
   populations, hybrid vigor for late-life fitness is expected in offspring
   obtained in crosses among populations selected for early-life fitness
   traits. We tested longevity of both sexes, female fecundity and male
   reproductive behavior for hybrid vigor by comparing hybrid and nonhybrid
   short-lived populations. Hybrid vigor was confirmed for male virility,
   mating speed and copulation duration, and longevity of both sexes at
   late ages. In contrast to males, the results on female fecundity in
   short-lived populations did not support mutation accumulation as a
   genetic mechanism for the evolution of this trait. Contrary to the
   prediction of this hypothesis, male mating ability indices and female
   fecundity in long-lived populations exhibited hybrid vigor at all
   assayed age classes. We demonstrate that nonhybrid long-lived
   populations diverged randomly regarding female and male reproductive
   fitness, indicating that sexually antagonistic selection, when
   accompanied with genetic drift for female fecundity and male virility,
   might be responsible for overriding natural selection in the
   independently evolving long-lived populations.
