However, the fact that both benign and harsh, as well as stable and fluctuating, environments can favour the evolution of cooperative breeding behaviour constitutes a paradox of environmental quality and sociality. Kin selection theory provides one important explanation for seemingly altruistic helping behaviour by non-breeding subordinates in cooperative breeding animals. For example, territorial choruses by male lions discourage intruders and are likely to benefit all contributors. In particular, understanding of the factors that promote the expression of helping behaviour in cooperatively breeding species remains weak, presumably because of the diverse nature of ecological and demographic drivers that promote sociality. 3 Cant ... M.A. In particular, understanding of the factors that promote the expression of helping behaviour in cooperatively breeding species remains weak, presumably because of the diverse nature of ecological and demographic drivers that promote sociality. - "PERSPECT IVE The ecology of cooperative breeding behaviour" Figure 1 The expected relationship between group size and productivity (in terms of direct fitness) for cooperatively breeding groups that form due to the two types of grouping benefits under benign (temporal) or high-quality (spatial) (solid lines) and harsh (temporal) or low-quality (spatial) environmental conditions (dashed … Sheng-Feng Shen,* Stephen T. Emlen, Walter D. Koenig and Dustin R. Rubenstein Abstract Ecology is a fundamental driving force for the evolutionary transition from solitary living to breeding cooperatively in groups. Stacey & Koenig 1990). Google Scholar. Ecology is a fundamental driving force for the evolutionary transition from solitary living to breeding cooperatively in groups. I strongly recommend this book to any biologist interested in behavioral ecology, sociality, or ornithology. Cooperative breeding, in which more than a pair of conspecifics cooperate to raise young at a single nest or brood, is widespread among vertebrates but highly variable in its geographic distribution. Learn vocabulary, terms, and more with flashcards, games, and other study tools. It provides an excellent review of many of the primary cooperative breeding studies of the last two decades, points the way to future research, and touches on some of the more general problems in behavioral ecology. Cambridge University Press, Cambridge Google Scholar Stiver KA, Dierkes P, Taborsky M, Balshine S (2004) Dispersal patterns and status change in a co-operatively breeding cichlid Neolamprologus pulcher: evidence from microsatellite analy-ses and behavioural observations. Cooperative behaviour has been shown to provide individuals with either direct fitness benefits (e.g. Ecology is a fundamental driving force for the evolutionary transition from solitary living to breeding cooperatively in groups. Although the evolution of cooperative breeding has often been REVIEW: BEHAVIORAL ECOLOGY Breeding Together: Kin Selection and Mutualism in Cooperative Vertebrates Tim Clutton-Brock In cooperatively breeding vertebrates, nonbreeding helpers raise young produced by dominant breeders. We also suggest that different types of environmental variation (spatial vs. temporal) select for societies that form because of the different grouping benefits, thus helping to resolve the paradox of why cooperative breeding evolves in such different types of environments. Kin selection theory provides one important explanation for seemingly altruistic helping behaviour by non-breeding subordinates in cooperative breeding animals. The cooperative breeding systems of birds have been a fertile testing ground for ideas on the evolution of societies, resulting in some of the most intensive studies of natural populations in ecology (e.g. helping kin to raise offspring) We study the behavioural ecology of cooperative breeding in the cichlid fish Neolamprologus pulcher/brichardi from Lake Tanganyika. It is commonly defined as any adaptation that has evolved, at least in part, to increase the reproductive success of the actor's social partners. The evolution of cooperation is a persistent problem for evolutionary biologists. Cooperative breeding, in which more than a pair of conspecifics cooperate to raise young at a single nest or brood, is widespread among vertebrates but highly variable in its geographic distribution.

Koenig: Libri in altre lingue mutualism, reciprocity) or indirect benefits (e.g. The main aim of behaviour is to increase the survival and reproductive success of individual organisms, so the question arises to what extent is behaviour cooperative, and what alternative theories can be used to understand cooperative behaviour? Start studying Behavioural Ecology - Cooperative breeding. In evolution, co-operation is the process where groups of organisms work or act together for common or mutual benefits.
