title: Monogamy and long-term pair bonding in vertebrates.
abstract: The term 'monogamy' represents a complex of mating systems that has been relalively neglected. Monogamy is generally associated with significant biparental care and is most common among birds. Recent work has addressed such aspects as the evolutionary incentives for (and value of) contributions by the male parent, how the distributions of females and critical nesting resources can promote monogamy, male defense of genetic paternity, the causes of long-term mate-retention in certain species, and the subtle means by which sexual selection operates within basically monogamous systems. New advances in testing genetic relatedness, especially DNA fingerprinting, promise much for the assessment of individual costs and benefits of monogamy.
