Advances in the Study of Behavior presents its first thematic volume, focusing on the physiological and behavioral mechanisms underlying parental care. The book discusses parental care both within and across taxa, with coverage of invertebrates and early vertebrates, fishes, amphibia, reptiles, mammals, birds, and nonhuman primates. A running theme throughout the chapters shows that parental care is anchored to the ecology, reproductive physiology, and embryonic development of a species.

The expansion is closely linked with human health requirements and societal needs for various goods and services provided by marine ecosystems.
