The mean and variability of early-life ecological conditions may have differing effects on life-history trade-offs and can have sex-specific effects. Male banded mongooses born in better early-life conditions invested more in reproduction but lived shorter lives, that is, “live-fast, die-young”; however, males born in more variable conditions lived longer and had greater reproductive success. We found no such effects in females.
