Gompertz和Weibull等理论模型通常用于研究人类和实验室或圈养动物的生存衰老。对于野生脊椎动物种群，生存衰老更常见的评估方法是拟合生存和年龄之间的简单线性或二次关系。通过对捕获-标记-再捕获（CMR）模型中的生存参数使用适当的约束，我们首次分析了Gompertz和双参数Weibull模型用于描述有蹄类动物自由放养种群中与年龄相关的死亡率的适用性。我们首先展示了如何处理Gompertz和两个参数的威布尔模型的背景下CMR分析。然后，我们进行了比较分析，在两个有蹄类物种的性别衰老模式高度对比，根据性选择的强度。我们的分析提供了支持Gompertz模型描述有蹄类动物的衰老模式。我们的研究结果的进化意义进行了讨论
Theoretical models such as those of Gompertz and Weibull are commonly used to study senescence in survival for humans and laboratory or captive animals. For wild populations of vertebrates, senescence in survival has more commonly been assessed by fitting simple linear or quadratic relationships between survival and age. By using appropriate constraints on survival parameters in Capture-Mark-Recapture (CMR) models, we propose a first analysis of the suitability of the Gompertz and the two-parameter Weibull models for describing aging-related mortality in free-ranging populations of ungulates. We first show how to handle the Gompertz and the two-parameter Weibull models in the context of CMR analyses. Then we perform a comparative analysis of senescence patterns in both sexes of two ungulate species highly contrasted according to the intensity of sexual selection. Our analyses provide support to the Gompertz model for describing senescence patterns in ungulates. Evolutionary implications of our results are discussed
