Weight at independence and its maintenance into adulthood. (a) Weight at independence is positively correlated with weight at 2 years (REML: χ₁²=36.29, p<0.001). (b) Pups that were supplementally fed during development are heavier at independence (REML: χ₁²=24.11, p<0.001), 6 months (χ₁²=6.79, p=0.005), 12 months (χ₁²=5.11, p=0.027), and 18 months (χ₁²=3.61, p=0.057). Figures show predicted means (±1 s.e.) after controlling for average group size between independence and 2 years (a) and random terms (a and b) (litter identity, p<0.05–0.01; mother and group identity, p>0.9). Values show number of individuals.
