title: Data from: Differential effects of early life adversity on male and female rhesus macaque lifespan

description: 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. Our study
 shows profound immediate effects of insults at birth on female infant
 cohorts and suggests that affected female adults are more robust. In
 contrast, adult males who experienced harsh conditions early in life
 showed an increased mortality risk at older ages as expected from
 hypotheses within the life course perspective. Our analysis suggests
 sex-specific selection pressures on life histories and highlights the need
 for studies addressing the effects of early life adversity across multiple
 life stages.
description: # Data from: Differential effects of early life adversity on male and
 female rhesus macaque lifespan --- 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. ##
 Description of the data and file structure Code files: 1-male infant
 survival analysis.R - These codes provide the workflow for the survival
 analysis of male infants. 2-female infant survival analysis.R - These
 codes provide the workflow for the survival analysis of female infants.
 3-male adult survival analysis.R - These codes provide the workflow for
 the survival analysis of male adults. 4-female adult survival analysis.R -
 These codes provide the workflow for the survival analysis of female
 adults. Data files: infant_survivalELA22.RData - These data describe the
 sex, fate, and adversities at birth experienced by individuals. mom:
 unique identification number of the mother of the focal individual
 exit_age: age at exit through death or right censorship of focal
 individual death: 1=focal individual died; 0= focal individual was right
 censored new_age: age at death or age at right censorship (i.e., 1 year of
 age, removal). Monkeys that survived to age one were treated as censored
 individuals and their age was floored at 1 female: 1=focal is female;
 0=focal is male first_time_mom_1: 1=yes, the mother of the focal
 individual is primiparous, I.e., the individual is a firstborn offspring;
 0=no imm_mom_death: impending maternal death, 1=yes, the mother of the
 focal individual died within one year of the individual's birth; 0=no
 hurricane_environment: 1=yes, the focal individual was born within one
 year of a hurricane event; 0=no n: number of adult females present during
 the onset of the focal's birth season q3density: 1=yes focal was born
 in birth season where ≥ 349 adult females were present; 0=no new_imm_CAI:
 sum of individual adversities experienced; individuals who experienced 3+
 adversities were grouped in "2+ adversity" category
 adult_survivalELA22.RData - These data describe the sex, fate, and early
 life adversities experienced by individuals who survived to adulthood (3
 years of age). mom: unique identification number of the mother of the
 focal individual age: age at exit through death or right censorship of
 focal individual death: 1=focal individual died; 0= focal individual was
 right censored female: 1=focal is female; 0=focal is male n: number of
 adult females present during the onset of the focal's birth season
 q3density: 1=focal individual was born in high density birth (≥ 349 adult
 females); 0=focal individual was born in regular season seasonsib: 1=focal
 individual had a younger sibling that was born a consecutive season after
 their own birth season; 0= focal individual did not experience a competing
 younger sibling Hurricane_Exp: 1=focal individual experienced a major
 hurricane event in their first three years of life; 0=focal individual did
 not experience a major hurricane event Maternal_Loss: 1=focal individual
 experienced maternal loss through maternal death or permanent removal
 during their first three years of life;0=focal individual did not
 experience maternal loss through maternal death or permanent removal
 first_time_mom_1: 1= focal individual had a primiparous mother, I.e., the
 individual is a firstborn offspring; 0=focal had an experienced mother
 New_CAI: sum of individual adversities experienced; focal individuals who
 experienced 4+ adversities were grouped in "3+ adversity"
