PRENATAL INFLUENCES ON REPRODUCTIVE LIFE-HISTORY STRATEGIES

Over the past two decades, evolutionary and behavioural ecologists have become increasingly interested in the adaptive consequences of intraspecific variability in life history and behavioural strategies. Recently, behavioural endocrinologists have begun to uncover surprising relationships between levels of prenatal exposure to gonadal hormones and variation in reproductive behaviour in adulthood. Such relationships may provide a causal explanation for many variations in adult phenotype that are of interest to behavioural and evolutionary ecologists.
