Early life adversity has sex-dependent effects on survival across the lifespan in rhesus macaques

Sam K. Patterson,

et al.

Abstract: Exposure to adversity during early life is linked to lasting detrimental effects on evolutionary fitness across many taxa. However, due to the challenges of collecting longitudinal data, especially in species where one sex disperses, direct evidence from long-lived species remains relatively scarce. Here we test the effects of early life adversity on male and female longevity in a free-ranging population of rhesus macaques (Macaca mulatta) at Cayo Santiago, Puerto Rico. We leveraged six decades of data to quan… Show more

“…Unlike previous studies in other mammals (e.g. [ 24 , 27 , 52 ]), we found no evidence for sex differences in the relationship between wELA and adult lifespan. Although males were less likely to survive their first winter and had shorter adult lifespans than females when they did survive, both sexes exhibited reduced longevity associated with cumulative exposure to harsh environmental conditions in early life.…”
