Differential effects of early life adversity on male and female rhesus macaque lifespan

Early life adversity predicts shorter adult lifespan in several animal taxa. Yet, work on long-lived primate populations suggests the evolution of mechanisms that contribute to resiliency and long lives despite early life insults. Here, we tested associations between individual and cumulative early life adversity and lifespan on rhesus macaques at the Cayo Santiago Biological Field Station using 50 years of demographic data. We performed sex-specific survival analyses at different life stages to contrast short-term effects of adversity (i.e., infant survival) with long-term effects (i.e., adult survival). Female infants showed vulnerability to multiple adversities at birth, but affected females who survived to adulthood experienced a reduced risk later in life. In contrast, male infants showed vulnerability to a lower number of adversities at birth, but those who survived to adulthood were negatively affected by both early life individual and cumulative adversity.

This is demographic data from a visual census collected and shared by the Caribbean Primate Research Center from the University of Puerto Rico Medical Sciences Campus. These data describe the demographic and early life adversity experiences of Cayo Santiago rhesus macaques.

Data and codes reproduce the survival analyses.

早期生活逆境（early life adversity）可预测多个动物类群的成年寿命更短。然而，针对长寿灵长类种群的研究表明，即便经历了早期生活打击，这些种群仍演化出了有助于恢复力与长寿的机制。

本研究基于卡约圣地亚哥生物野外站（Cayo Santiago Biological Field Station）的50年人口统计数据，对恒河猴（rhesus macaque）的个体性与累积性早期生活逆境和寿命之间的关联进行了检验。我们针对不同生命阶段开展了性别特异性生存分析，以对比逆境的短期效应（即幼崽存活率）与长期效应（即成年存活率）。雌性幼崽在出生时便对多种逆境表现出易感性，但存活至成年的受影响雌性个体在后续生命中的死亡风险有所降低。与之相反，雄性幼崽在出生时仅对较少数量的逆境表现出易感性，但存活至成年的雄性个体则会受到早期个体性与累积性逆境的双重负面影响。本研究表明了深远的[原文截断]……
