Data from: Offspring fitness and the optimal propagule size in a fluctuating environment
Propagule size is an important maternal effect on offspring fitness and phenotype in birds and other oviparous animals. The performance of propagules often increases with size, but a fluctuating environment may introduce temporal variation in the optimal phenotype. Understanding these mechanisms wil...

Propagule size is an important maternal effect on offspring fitness and phenotype in birds and other oviparous animals.
