Abstract excerpt
Antagonistic trade-offs between early-life fitness and somatic maintenance are predicted to maintain variation in longevity, yet empirical support is scarce. Shephard et al. (2026) experimentally tested whether such trade-offs are concealed under typical developmental conditions using Mexican spadefoot tadpoles (Spea multiplicata) reared on typical or atypical diets. The atypical diet revealed cryptic genetic...
