Investment Strategies of Breeders in Avian Cooperative Breeding Systems

  • 1 August 1999
An individual's optimal investment in young depends partly on the number of individuals caring for the same brood. In cooperative breeders, the investment strategy of parents with helpers isExpand

Predictable males and unpredictable females: sex difference in repeatability of parental care in a wild bird population
Repeatability of parental care, let alone heritability of care, has been rarely measured, although there has been much research linking sexual selection to male parental care and also examiningExpand

Inclusive fitness theory and eusociality
Arising from M. A. Nowak, C. E. Tarnita & E. O. Wilson 466, 1057–1062 (2010)10.1038/nature09205; Nowak et al. replyNowak et al. argue that inclusive fitness theory has been of little value inExpand

  • 12 November 2009
The evolution of cooperation among animals has posed a major problem for evolutionary biologists, and despite decades of research into avian cooperative breeding systems, many questions about theExpand

Experimental evidence for kin-biased helping in a cooperatively breeding vertebrate
The widespread belief that kin selection is necessary for the evolution of cooperative breeding in vertebrates has recently been questioned. These doubts have primarily arisen because of the paucityExpand

HERITABILITY OF PARENTAL EFFORT IN A PASSERINE BIRD
Abstract The study of the evolution of parental care is central to our understanding of social systems, sexual selection, and interindividual conflict, yet we know virtually nothing about the geneticExpand

A conceptual framework for the colonisation of urban areas: the blackbird Turdus merula as a case study
Despite increasing interest in urban ecology the factors limiting the colonisation of towns and cities by species from rural areas are poorly understood. This is largely due to the lack of a detailedExpand

Recruitment and survival of immature seabirds in relation to oil spills and climate variability.
1. In long-lived animals with delayed maturity, the non-breeding component of the population may play an important role in buffering the effects of stochastic mortality. Populations of colonialExpand

Oil pollution and climate have wide-scale impacts on seabird demographics.
Oil spills often spell disaster for marine birds caught in slicks. However, the impact of oil pollution on seabird population parameters is poorly known because oil spills usually occur in winteringExpand

Candidate gene polymorphisms for behavioural adaptations during urbanization in blackbirds
Successful urban colonization by formerly rural species represents an ideal situation in which to study adaptation to novel environments. We address this issue using candidate genes for behaviouralExpand
