This chapter summarizes important advances in the understanding of the mechanisms underlying the costs and benefits of parental care. It starts by analysing the nature of parental resources, addressing also the possibility of cost-free resources. It then reviews short and long-term benefits of parental care and how parents adjust offspring phenotypes to attain such benefits. Similarly, it reviews physiological and non-physiological costs of parental care and the current support for a link with fitness. It concludes that, despite important recent advances, the integration of proximate mechanisms into ultimate explanations is still far from successful.

Keywords:   cost-free resources, parental resources, offspring phenotypes, proximate mechanisms
