Antagonistic effect of helpers on breeding male and female survival in a cooperatively breeding bird
Matthieu Paquet, Auteur ; Claire Doutrelant, Auteur ; Ben J. Hatchwell, Auteur ; Claire N. Spottiswoode, Auteur ; Rita Covas, AuteurCooperatively breeding species are typically long lived and hence, according to theory, are expected to maximize their lifetime reproductive success through maximizing survival. Under these circumstances, the presence of helpers could be used to[...]

Philippa R. Gullett, Auteur ; Ben J. Hatchwell, Auteur ; Robert A. Robinson, Auteur ; Karl L. Evans, AuteurProductivity is a key demographic trait that can be influenced by climate change, but there are substantial gaps in our understanding of the impact of weather on productivity and recruitment in birds. Weather is known to influence reproductive s[...]
Article
Stuart P. Sharp, Auteur ; Ben J. Hatchwell, AuteurContact calls are ubiquitous among birds and are important in mediating social interactions. Despite this, the structure and function of these vocalizations have received relatively little attention, and the ontogeny of all bird calls is poorly [...]
Article
Jin-Won Lee, Auteur ; Ben J. Hatchwell, AuteurA growing number of bird species are known to have fine-scale genetic structure during the breeding season, with relatives breeding in close vicinity. Such genetic structure often has fitness consequences for parents, and sex ratio theory predic[...]
Article
Ben J. Hatchwell, Auteur ; Stuart P. Sharp, Auteur ; Andrew P. Beckerman, Auteur ; Jessica Meade, AuteurThe evolution of cooperation is a persistent problem for evolutionary biologists. In particular, understanding of the factors that promote the expression of helping behaviour in cooperatively breeding species remains weak, presumably because of [...]

Jin-Won Lee, Auteur ; Myun-Sik Kim, Auteur ; Terry Burke, Auteur ; Ben J. Hatchwell, AuteurUnderstanding the factors that affect the occurrence of extrapair paternity (EPP) is one of the central issues in sexual selection. We investigated genetic parentage and the ecological factors affecting patterns of EPP in the vinous-throated par[...]
Article
Jin-Won Lee, Auteur ; Hee-Yoon Kim, Auteur ; Ben J. Hatchwell, AuteurThe amount of food delivered by parents to their chicks is affected by various life history traits as well as environmental and social factors, and this investment ultimately determines the current and future fitness of parents and their offspri[...]

Birkhead, AuteurThe population of common guillemots Uria aalge on Skomer Island, Wales has been monitored since 1963, and in the last 30 yr has increased at an almost constant rate of 5% yr-1. A previous attempt to model the population based on intrinsic demogr[...]

Hatchwell, AuteurStructures built by animals, such as nests, mounds and burrows, are often the product of cooperative investment by more than one individual. Such structures may be viewed as a public good, since all individuals that occupy them share the benefit[...]
