摘要

由于生殖衰老,通常假设雄性年龄的增加会降低雄性的生育能力和后代的质量。然而,男性年龄增长对生殖能力和后代质量的影响并不总是有害的。例如,年长的父亲可能会通过长期投资于生殖来缓冲生殖衰老的影响。同样,年老时还能存活下来进行繁殖的雄性,可能携带着赋予高生存能力的等位基因(生存能力选择),然后由后代继承,也可能具有高繁殖潜力(选择性消失)。要区分这些机制,需要对父代的存活率、生殖能力以及后代的质量进行综合实验研究,而目前还缺乏这方面的研究。通过对黑腹果蝇的横断面研究,我们检验了父代受孕年龄(PAC)对父代生存和繁殖成功率以及子代寿命的影响。我们发现,高龄交配与未来雄性存活率下降有关,这表明交配引起的死亡率可能是由于高龄父亲体弱所致。我们没有发现终端投资的证据,并表明父亲的生殖衰老直到成年晚期才开始。此外,我们还发现,随着父亲寿命的延长,其生育后代的概率也会增加,这仅适用于年长的 PAC 处理。最后,我们还发现,由于生存能力的选择,年长父亲所生的儿子比年轻父亲所生的儿子更长寿。总之,我们的研究结果表明,父亲年龄的增加并不一定会对后代产生有害影响,甚至可能导致年长的父亲生出更长寿的后代。

What does not kill you makes you stronger? Effects of paternal age at conception on fathers and sons.

Advancing male age is often hypothesized to reduce both male fertility and offspring quality due to reproductive senescence. However, the effects of advancing male age on reproductive output and offspring quality are not always deleterious. For example, older fathers might buffer the effects of reproductive senescence by terminally investing in reproduction. Similarly, males that survive to reproduce at an old age might carry alleles that confer high viability (viability selection), which are then inherited by offspring, or might have high reproductive potential (selective disappearance). Differentiating these mechanisms requires an integrated experimental study of paternal survival and reproductive performance, as well as offspring quality, which is currently lacking. Using a cross-sectional study in Drosophila melanogaster, we test the effects of paternal age at conception (PAC) on paternal survival and reproductive success, and on the lifespans of sons. We discover that mating at an old age is linked with decreased future male survival, suggesting that mating-induced mortality is possibly due to old fathers being frail. We find no evidence for terminal investment and show that reproductive senescence in fathers does not onset until their late-adult life. Additionally, we find that as a father's lifespan increases, his probability of siring offspring increases for older PAC treatments only. Lastly, we show that sons born to older fathers live longer than those born to younger fathers due to viability selection. Collectively, our results suggest that advancing paternal age is not necessarily associated with deleterious effects for offspring and may even lead to older fathers producing longer-lived offspring.
