Demography of male reproductive queues in cooperatively breeding superb fairy-wrens Malurus cyaneus.
1. Subordinate helpers in cooperative societies may gain both immediate and future benefits, including paternity and territorial inheritance. However, if such opportunities correlate with rank in the queue, it is unclear why such queues should be stable. 2. In cooperatively breeding superb fairy-wrens Malurus cyaneus, only males are generally philopatric, and form stable hierarchical queues for...
متن کاملCan we measure the benefits of help in cooperatively breeding birds: the case of superb fairy-wrens Malurus cyaneus?
1. Correlational studies of reproductive success are plagued by difficulty over the direction of causation. For example, improved reproductive success with age can result from increased experience or reproductive effort, or selection against low-quality phenotypes that survive poorly. An association between supernumeraries and reproductive success in cooperative breeders can arise either becaus...
متن کاملThe vegetation requirements of Superb Fairy-wrens (Malurus cyaneus) in non-urban edge and urbanised habitats
Urbanisation has created an environment with a broad spectrum of habitats of differing quality for birds. Understanding habitat characteristics is necessary for effective conservation of species in urban environments. We investigated the vegetation requirements of a small, shrub-nesting, Australian bird, the Superb Fairy-wren (Malurus cyaneus), and the relative quality of urban habitats in the ...
متن کاملSubordinate superb fairy-wrens (Malurus cyaneus) parasitize the reproductive success of attractive dominant males.
Explanations of cooperative breeding have largely focused on the indirect benefits philopatric offspring gain from investing in kin. However, recent molecular studies have revealed that in many species subordinates provision unrelated offspring. This has led to the re-evaluation of the direct and indirect benefits of helping behaviour. In this study, we used microsatellite genotyping to assess ...
