The Evolution and Ecology of Cooperative Breeding in Vertebrates
Cooperative breeding – in which some adults forgo independent breeding and remain as subordinates within a group helping to raise the offspring of others – occurs in between 3% and 10%of vertebrates. The structure of such systems varies greatly, from pairswith helpers-at-the-nest to communal breeders, andmay include younghelpers or post-reproductive ‘grandparents’. That some individuals spend p...
متن کاملTemporal Environmental Variability Drives the Evolution of Cooperative Breeding in Birds
Many vertebrates breed in cooperative groups in which more than two members provide care for young. Studies of cooperative breeding behavior within species have long highlighted the importance of environmental factors in mediating the paradox of why some such individuals delay independent breeding to help raise the offspring of others. In contrast, studies involving comparisons among species ha...
متن کاملThe evolution of cooperative breeding; is there cheating?
Over the past four decades biologists have developed a body of theory to explain the evolution of cooperative behavior. Three key conditions have been modeled in which the fitness of individuals can be enhanced by their cooperative acts. Cooperation can evolve and be stable when (i) cooperative individuals share genes with the recipients (Hamilton, 1964a,b), (ii) when cooperation is a byproduct...
متن کاملBreeding together: kin selection and mutualism in cooperative vertebrates.
In cooperatively breeding vertebrates, nonbreeding helpers raise young produced by dominant breeders. Although the evolution of cooperative breeding has often been attributed primarily to kin selection (whereby individuals gain "indirect" benefits to their fitness by assisting collateral relatives), there is increasing evidence that helpers can be unrelated to the young they are raising. Recent...
متن کاملPredation risk drives social complexity in cooperative breeders.
Predation risk is a major ecological factor selecting for group living. It is largely ignored, however, as an evolutionary driver of social complexity and cooperative breeding, which is attributed mainly to a combination of habitat saturation and enhanced relatedness levels. Social cichlids neither suffer from habitat saturation, nor are their groups composed primarily of relatives. This demand...
