To account for the effect of individual females on egg components, egg mass, and hatchling size, we treated female identity as a random effect in linear models and used the residuals of the response variables (ie, egg component masses, egg mass, hatchling mass) from these models in further linear regression analyses. Adopt a sea turtle nest adopt a hatchling the amount of eggs deposited in the nest depends on the species and size of the individual the sea turtle . The primary objective of this study was to identify non‐predation‐related sources of egg mortality in natural nests of the painted turtle (c picta), and evaluate how natural selection operates on maternal reproductive parameters (timing of nesting and egg size) and nest‐site choice because most microevolutionary studies evaluate .
