The state can also intervene and terminate parental rights involuntarily if the father abandons, abuses or neglects the child.
Around us in nature, though, we see a vast diversity of parental care strategies. Bird parents, like us, cooperate tirelessly to raise chicks, while most mammal mothers have to suckle alone; insect parents usually abandon their eggs to the elements, but occasionally, very rarely, they tend single offspring intensively.
Fishes may broadcast-spawn millions of eggs into the ocean, but some fathers prepare nests and carefully fan their eggs with oxygenated water until they hatch. Parental care, however defined, is a fundamental investment by an animal into the fitness of its offspring, ranging from the briefest of periods of guarding eggs to intensive tending and feeding of offspring through to adulthood and sometimes beyond.
Parental care occurs all over the animal kingdom and takes many forms, is performed by either or both parents, and is an arena for some amazing stories of cooperation, but it can be the source of extensive conflict.
After an initial rush of theory, empirical descriptions, and physiological measurements, parental care research has now settled into a pattern-finding period in which comparative researchers are identifying tantalizing trends in testing the early theories, behavioral ecologists are providing ever more credible measurements of costs and benefits of different components of care, and recently, perhaps most excitingly, geneticists are beginning to exert their strong quantitative influence on the field.
With these developments, model systems are becoming increasingly important, such as great tits, sticklebacks, earwigs, and burying beetles, all of which play a large part in the literature cited here.
As ever, vast swathes of diversity remain unstudied, and when detailed experimental and genetic manipulations are not possible, the natural historian still has a job making careful observations.
Room remains also for relatively major theoretical advances, as the following sections will show. General Overviews No reader serious about studying parental care should be without Clutton-Brockthe authoritative volume on the subject.
Throughout this article this work will be cited sparingly only when especially relevant, but the reader should consult this book generally as a first step for all sections of this article. For more general context within behavioral ecology, Davies, et al. For an update to Clutton-Brock and for more bleeding-edge research on the topic and summaries of very recent work, including for example the latest genetics, Royle, et al.
Allport is a popular and comprehensive treatment of the topic suitable for dipping into for pleasure. Where relevant, general overviews of topics covered by specific sections are cited in the section in question.
A Natural history of parenting. Engagingly written popular treatment of the topic, suitable for all levels from undergraduate upward, covering many topics addressed here and well worth dipping into for pleasure as well as research. The evolution of parental care. Classic, comprehensive, extremely well-written and interesting text.
The first port of call for anyone seriously interested in this subject from undergraduates to advanced researchers. On technical details it is showing its age slightly and readers requiring the absolute cutting edge should consult Royle, et al. An introduction to behavioural ecology.
Excellent and thoroughly readable introduction to all key concepts in behavioral ecology. This very recent edition provides a useful update to the well-known volume by Krebs and Davies. Contains an entire chapter on parental care and its evolution. Intended for undergraduates but suitable for all levels.
Slightly more in-depth than Davies, et al. Suitable for undergraduates in their final year and more advanced researchers.The Impact of Non-Parental Child Care on Child Development: Evidence from the Summer Participation “Dip” Chris M.
Herbst. Arizona State University. Aug 15, · Neural correlates of human parental care. In recent years, it has been possible to explore the biological correlates of human parenting through a variety of approaches, including brain imaging of the response to infant stimuli, endocrine studies, and gene association studies.
The struggle between the instincts of self-preservation and parental love then became perceptible. They flew round the vessel, then vanished for awhile, then suddenly returned to their hungry family, and stretching their open beaks towards them, seemed to lament that no food was to be found.
