Intermittent breeding is associated with breeding group turnover in a cooperatively breeding bird

Oecologia, 2020
Intermittent 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.

Cooperative breeding

2005
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.

Cooperative breeding

1999
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 ...

Cooperative Breeding instead of Cooperative Killing

2015
Foreword | In his outstanding target article on”The Ritual Origins of Humanity”, Matt Rossano presented empirical findings and theses from the forefront of interdisciplinary anthropological studies, ranging from biology to psychology and sociology. But I will argue that he has inherited a classical bias that is unfortunately still alive in evolutionary

Cooperative Breeding and Adolescent Siblings

Current Anthropology, 2009
In humans, alloparents are usually thought to be grandmothers and adolescent girls. Although many studies have examined the influence of grandmothers on child outcomes, fewer have explored the effect of adolescents on such outcomes. We tested the hypothesis that in a community of Ecuadorian Shuar horticulturists, adolescent girls would have a positive ...

Advancing cooperative breeding research with a peer-reviewed and “live” Cooperative-Breeding Database (Co-BreeD)

AbstractResearch on cooperative breeding (a system with the core characteristic of individuals providing care for the offspring of others) is important for understanding sociality and cooperation. However, large-scale comparative analyses on the drivers and consequences of cooperation frequently use considerably inaccurate datasets (e.g.

Cooperative Breeding in Mammals

1996
Cooperative breeding refers to a social system in which individuals other than the parents provide care for the offspring. Since individuals delay breeding and invest in the offspring of others, cooperative breeding poses a challenge to a Darwinian explanation of the evolution of social behaviour. The contributors to this book explore the evolutionary,

Cooperative and Communal Breeding

2019
The study of cooperative breeding in birds has a long history in the New World tropics, beginning with Alexander Skutch’s seminal observations of helpers at the nest. Recent studies of Neotropical birds have revealed a diversity of cooperative systems, ranging from small family groups to complex societies composed of relatives and immigrants.
