灵长类动物的后代往往在断奶后很长一段时间内都要依赖母亲，而在生命早期经历母亲死亡的后代在整个生命周期中都可能遭受健康状况的大幅下降。在这里，我们利用来自8个野生灵长类种群（7个物种）的数据来研究两个未被充分认识的途径，这些途径与母亲早期死亡和后代健康有关，这与孤儿对后代生存的直接影响不同。首先，我们表明，在7个物种中，有5个物种的后代在母亲还活着的时候，在母亲死亡之前的几年里面临着存活率下降的问题。其次，我们在三个物种（猴、狒狒和蓝猴）中发现了早期母性丧失的代际效应，例如，一代经历的早期母性死亡会导致下一代后代存活率降低。我们的研究结果对灵长类动物缓慢生活史的进化具有重要意义，因为它们表明，母亲的状况和生存对后代的适应性比以前认识到的更重要。
Primate offspring often depend on their mothers well beyond the age of weaning, and offspring that experience maternal death in early life can suffer substantial reductions in fitness across the lifespan. Here we leverage data from eight wild primate populations (seven species) to examine two underappreciated pathways linking early maternal death and offspring fitness that are distinct from direct effects of orphaning on offspring survival. First, we show that, for five of the seven species, offspring face reduced survival during the years immediately preceding maternal death, while the mother is still alive. Second, we identify an intergenerational effect of early maternal loss in three species (muriquis, baboons, and blue monkeys), such that early maternal death experienced in one generation leads to reduced offspring survival in the next. Our results have important implications for the evolution of slow life histories in primates, as they suggest that maternal condition and survival are more important for offspring fitness than previously realized.
