Descriptive statistics of relevant life history traits along time.

Note. Sample, sample size; Decade, the decade when mothers gave their first births; M-AFR, maternal age at first reproduction; M-ALR, maternal age at last reproduction; M-span, maternal reproductive lifespan; M-BI, maternal birth interval (calculated by considering only the cases where reproductive span was larger than zero); Quantity, offspring quantity or maternal lifetime fertility; Survival, offspring survival rate at age 15; Breeding, offspring breeding probability; M-LRS, maternal lifetime reproductive success (calculated using the algorithm mentioned in section 2.2.); Correlation, the correlation between the specific traits (M-AFR, M-ALR, etc.) and the year when giving the first birth and is sample estimate of Pearson's correlation coefficient; for weighted traits (offspring survival rate and breeding probability, and maternal lifetime reproductive success), mean and standard error are calculated using weighted formulas (code available from authors); for weighted traits (offspring survival rate and breeding probability, and maternal lifetime reproductive success), correlation coefficients are calculated using only the records of mothers with weight as 1.
