Integrating Cooperative Breeding Into Theoretical Concepts of Cooperation [PDF]
Behavioural Processes, 2007 In cooperative breeding systems, some individuals help to raise offspring that are not their own. While early explanations for such altruistic behaviour were predominantly based on kin selection, recent evidence suggests that direct benefits may be important in the maintenance of cooperation.

Biological Reviews, 2023 Cooperative breeding (i.e. when alloparents care for the offspring of other group members) has been studied for nearly a century. Yet, inconsistent definitions of this breeding system still hamper comparative research.

Cooperative breeding in mammals
Trends in Ecology & Evolution, 1994Cooperative breeding in mammals covers a diversity of breeding systems. In all cases, however, Individuals assist in the rearing of offspring other than their own. Recent research has highlighted some of the factors responsible for variation both within and between species.

Cooperative Breeding and Monogamy in Mammalian Societies [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2012 Comparative studies of social insects and birds show that the evolution of cooperative and eusocial breeding systems has been confined to species where females mate completely or almost exclusively with a single male, indicating that high levels of average kinship between group members are necessary for the evolution of reproductive altruism.

Cooperative Breeding in Marmots
Oikos, 1999Whenever individuals live in stable social groups and not all individuals breed, group members may breed cooperatively. While well-documented in a variety of birds and mammals, there is some controversy over whether, and to what degree, sciurid rodents breed cooperatively.

Intermittent breeding is associated with breeding group turnover in a cooperatively breeding bird
Oecologia, 2020Intermittent breeding, in which an adult skips a breeding opportunity, can represent a non-adaptive constraint or an adaptive response to the tradeoff between current and future reproduction. In group-living animals, the social group may also affect the frequency of reproduction, but this possibility has received little attention.

Familiarity breeds cooperation
Nature, 1998Many theoretical models have been developed to study the conditions under which unrelated individuals should cooperate or not cooperate. But such behaviour is rarely ‘all or nothing’, and new mathematical models allow the optimal level of cooperation to be determined.

Abstract Cooperative breeding, sometimes referred to as communal breeding, is a rare and specialized phenomenon that occurs in fewer than three per cent of the world’s approximately 9700 species of extant birds. Cooperative breeding is defined by the presence in a stable social unit of non-breeding ‘helpers’, which assist in the care of ...

Abstract Cooperative breeding birds live in social groups. In the group some birds, the “helpers”, help rear the young of other individuals, the breeders. Helpers may provide relief to the breeders by taking part in the care of a brood, and the helpers may increase the number of brood young that survive. This behavior is curious.
