These challenges can range from predators to harsh environments and limited resources. Parental care helps increase the survival chances of young by providing food, protection, or guidance.
Furthermore, Judson explores how parental care can differ between species based on their ecological niches and reproductive strategies. Cooperative breeders, such as naked mole rats, live in colonies where only a few individuals reproduce while others assist in caring for the young. Alternatively, brood parasites, like cuckoos, lay their eggs in the nests of other species, tricking them into providing parental care.
The chapter concludes by underlining the trade-offs faced by parents engaging in care. While investing in parental care provides benefits to offspring, it also comes at a cost to the parent’s own survival and reproduction. Ultimately, parental care in the animal kingdom is a complex and dynamic phenomenon that has shaped diverse strategies for optimizing reproductive success and ensuring the survival of future generations.
