Data from: Variation in offspring development is driven more by weather and maternal condition than predation risk
1. Variation in offspring development is expected to be driven by constraints on resource allocation between growth and maintenance (e.g., thermoregulation). Rapid post-natal development decreases predation risk, while inclement weather likely prolongs development. For taxa with parental care, paren...
