title: Data from: Testing frameworks for early life effects: The developmental constraints and adaptive response hypotheses do not explain key fertility outcomes in wild female baboons

description: In evolutionary ecology, two classes of explanations are frequently
 invoked to explain "early life effects" on adult outcomes.
 Developmental constraints (DC) explanations contend that costs of early
 adversity arise from limitations adversity places on optimal development.
 Adaptive response (AR) hypotheses propose that later life outcomes will be
 worse when early and adult environments are poorly "matched."
 Here, we use recently proposed mathematical definitions for these
 hypotheses and a quadratic-regression based approach to test the long-term
 consequences of variation in developmental environments on fertility in
 wild baboons. We evaluate whether low rainfall and/or dominance rank
 during development predict three female fertility measures in adulthood,
 and whether any observed relationships are consistent with DC and/or AR.
 Neither rainfall during development nor the difference between rainfall in
 development and adulthood predicted any fertility measures. Females who
 were low-ranking during development had an elevated risk of losing infants
 later in life, and greater change in rank between development and
 adulthood predicted greater risk of infant loss. However, both effects
 were statistically marginal and consistent with alternative explanations,
 including adult environmental quality effects. Consequently, our data do
 not provide compelling support for either of these common explanations for
 the evolution of early life effects.
description: These data sets correspond to the analyses described in Rosenbaum et al.
 2024, “Testing frameworks for early life effects: the developmental
 constraints and adaptive response hypotheses do not explain key fertility
 outcomes in wild female baboons.” (BIORXIV/2024/590627) All three of the
 below data sets are described in detail in Section 2 and Tables 2 and 3 in
 the main text of the paper: Conception data set
 (conception_data_4.16.2024.dta OR conception_data_4.16.2024.csv) Live
 birth data set (live_birth_data_4.16.2024.dta OR
 live_birth_data_4.16.2024.csv) Infant survival data set
 (infant_survival_data_4.16.2024.dta OR infant_survival_data_4.16.2024.csv)
 The below data set is described in Section D and Table A5 in the
 supplementary materials: Restricted version of the conception data set
 (conception_data_restricted_4.16.2024.dta OR
 conception_data_restricted_4.16.2024.csv) Outcome variables (1 per data
 set; “conception” is the outcome in both conception_data_4.16.2024 *and*
 conception_data_restricted_4.16.2024) conception: did the female subject
 conceive in the calendar month that corresponds with this observation,
 given that she was cycling on the first day of the calendar month (0=N,
 1=Y)? livebirth: did the female subject give birth to a live infant, given
 that she was pregnant (0=N, 1=Y)? infsurvival: did the female subject’s
 infant live to 70 weeks, given that she gave birth to a live infant (0=N,
 1=Y)? Predictor variables (common to all four data sets) age: age of the
 female subject when the fertility event occurred (described in detail in
 supplementary Table A.4) age2: age variable squared group: identifies the
 social group the female subject lived in when the fertility event occurred
 grp_size: total number of animals living in the female subject’s social
 group when the fertility event occurred (described in detail in
 supplementary Table A.4) id: identity of the female subject e0rank:
 proportional rank that the subject’s mother held in the year following the
 subject’s birth (i.e., early life rank; described in detail in
 supplementary Tables A1-A3) e1rank: proportional rank that the subject
 held when the fertility event occurred (i.e., adult rank; described in
 detail in Table 3 and Figure 1 in the main text, and in supplementary
 Tables A1-A3) e0rain: mean monthly rainfall (in mm) in the first 12 months
 of the subject’s life (i.e., early life rainfall; described in detail in
 supplementary Tables A1-A3 ) e1rain: mean monthly rainfall (in mm) in the
 12 months preceeding the fertility event (i.e., adult rainfall; described
 in detail in Table 2 and Figure 1 in the main text, and in supplementary
 Tables A1-A3) rain_analysis_sample: indicates whether a given observation
 was used in the analyses that examine the effects of rainfall (0=was not
 used, 1=was used). In cases where this variable = 0, e0rain will be
 missing. To replicate the analyses presented in the paper, please see the
