众所周知，生殖是生命中代价高昂的一个阶段，个体会受到伤害、感染疾病和能量的权衡。这些成本的强度应该受到生活史策略的影响，在长寿物种中，雌性可能会被选择来减轻繁殖成本，因为寿命是其繁殖成功的重要组成部分。在这里，我们报告的证据表明，两个成本的繁殖，可能会影响野生雌性狒狒的生存受伤的风险和延迟伤口愈合。基于对肯尼亚安博塞利生态系统29年的观察，我们发现野生雌性狒狒在最有可能排卵的日子里受伤的风险最高。此外，哺乳期女性伤口愈合速度比怀孕或骑自行车的女性，这表明哺乳和免疫功能之间可能存在权衡。我们还发现，受伤风险和伤口愈合与优势等级和年龄的变化：老年和低地位的女性比年轻或高地位的女性更容易受伤，老年女性比年轻女性愈合较慢。我们的研究结果支持了野生非人灵长类动物经历繁殖的能量和免疫成本的想法，它们有助于阐明长寿物种的生活史权衡。
Reproduction is a notoriously costly phase of life, exposing individuals to injury, infectious disease, and energetic trade-offs. The strength of these costs should be influenced by life history strategies, and in long-lived species, females may be selected to mitigate costs of reproduction because life span is such an important component of their reproductive success. Here, we report evidence for two costs of reproduction that may influence survival in wild female baboons-injury risk and delayed wound healing. Based on 29 years of observations in the Amboseli ecosystem, Kenya, we found that wild female baboons experienced the highest risk of injury on days when they were most likely to be ovulating. In addition, lactating females healed from wounds more slowly than pregnant or cycling females, indicating a possible trade-off between lactation and immune function. We also found variation in injury risk and wound healing with dominance rank and age: Older and low-status females were more likely to be injured than younger or high-status females, and older females exhibited slower healing than younger females. Our results support the idea that wild nonhuman primates experience energetic and immune costs of reproduction and they help illuminate life history trade-offs in long-lived species.
