Mirte Bosse, Auteur ; Lewis G. Spurgin, Auteur ; Veronika N. Laine, Auteur ; Ella F. Cole, Auteur ; Josh A. Firth, Auteur ; Phillip Gienapp, Auteur ; Andrew G. Gosler, Auteur ; Keith McMahon, Auteur ; Jocelyn Poissant, Auteur ; Irene Verhagen, Auteur ; Martien A. M. Groenen, Auteur ; Kees van Oers, Auteur ; Ben C. Sheldon, Auteur ; Marcel E. Visser, Auteur ; Jon Slate, AuteurRecent natural selection in a wild bird Many studies have found evidence of rapid evolution in response to environmental change. In most cases, there has been some suggestion of which traits might be most responsive ahead of time. Bosse et al. [...]
Article
Nicole D. Milligan, Auteur ; Reinder Radersma, Auteur ; Ella F. Cole, Auteur ; Ben C. Sheldon, AuteurAn individual's foraging behaviour and time allocated to feeding have direct consequences for its fitness. Despite much research on population-level foraging decisions, few studies have investigated individual differences in fine-scale daily for[...]

Damien R. Farine, Auteur ; Josh A. Firth, Auteur ; Lucy M. Aplin, Auteur ; Ross A. Crates, Auteur ; Antica Culina, Auteur ; Colin J. Garroway, Auteur ; Camilla A. Hinde, Auteur ; Lindall R. Kidd, Auteur ; Nicole D. Milligan, Auteur ; Ioannis Psorakis, Auteur ; Reinder Radersma, Auteur ; Brecht Verhelst, Auteur ; Bernhard Voelkl, Auteur ; Ben C. Sheldon, AuteurBoth social and ecological factors influence population process and structure, with resultant consequences for phenotypic selection on individuals. Understanding the scale and relative contribution of these two factors is thus a central aim in e[...]
Article
Anne Charmantier, Auteur ; Christopher Perrins, Auteur ; Robin H. McCleery, Auteur ; Ben C. Sheldon, Auteur ; Associate Editor: Robert Montgomerie, Auteur ; Editor: Jonathan B. Losos, AuteurAbstract: Life‐history traits in wild populations are often regarded as being subject to directional selection, and the existence of substantial variation and microevolutionary stasis of these characters is therefore a problem in need of explana[...]
Article
Oscar Vedder, Auteur ; Sandra Bouwhuis, Auteur ; Ben C. Sheldon, AuteurNatural selection can vary in magnitude, form and direction, yet the causes of selection, and of variation in selection, are poorly understood. We quantified the effect of a key predator (Eurasian sparrowhawks) on selection on fledging body mass[...]
Article
Simon C. Griffith, Auteur ; Iain Barr, Auteur ; Ben C. Sheldon, Auteur ; Louise V. Rowe, Auteur ; Terry Burke, AuteurA recent study reported the incidence of intraspecific brood parasitism (IBP) in the blue tit, based on differences in pigmentation between eggs within clutches and the appearance of multiple eggs within a nest in a single day. Here we present d[...]
Article
Ana Claudia Norte, Auteur ; Ben C. Sheldon, Auteur ; Jose P. Sousa, Auteur ; Jaime A. Ramos, AuteurHealth state parameters in natural populations can be used as bioindicators of environmental health if they respond to environmental cues. We studied to which extent health state parameters (morphological, biochemical, and haematological) were d[...]
Article
Matt J. Wood, Auteur ; Dylan Z. Childs, Auteur ; Alicia S. Davies, Auteur ; Olof Hellgren, Auteur ; Charlie K. Cornwallis, Auteur ; Chris M. Perrins, Auteur ; Ben C. Sheldon, AuteurQuantifying the factors that predict parasite outbreak and persistence is a major challenge for both applied and fundamental biology. Key to understanding parasite prevalence and disease outbreaks is determining at what age individuals show sign[...]
Article
Antica Culina, Auteur ; Shelly Lachish, Auteur ; Ben C. Sheldon, AuteurAlthough they have the potential to strongly influence individual fitness and the dynamics and productivity of populations, the survival consequences of pairing outcomes and the influence of current pairing outcomes on those in the future have r[...]
Article
Teddy A. Wilkin, Auteur ; Lucy E. King, Auteur ; Ben C. Sheldon, AuteurVariation in early nutrition is often a strong predictor of offspring condition and fitness. In the case of woodland passerine birds, nestling diet is determined by the spatiotemporal distribution of prey items such as caterpillars during the ne[...]
Article
Sandra Bouwhuis, Auteur ; Anne Charmantier, Auteur ; Simon Verhulst, Auteur ; Ben C. Sheldon, AuteurP>1. Longitudinal studies of various vertebrate populations have recently demonstrated senescent declines in reproductive performance and/or survival probability with age to be almost ubiquitous in nature. Little is known, however, about the ext[...]

Ross A. Crates, Auteur ; Josh A. Firth, Auteur ; Damien R. Farine, Auteur ; Colin J. Garroway, Auteur ; Lindall R. Kidd, Auteur ; Lucy M. Aplin, Auteur ; Reinder Radersma, Auteur ; Nicole D. Milligan, Auteur ; Bernhard Voelkl, Auteur ; Antica Culina, Auteur ; Brecht L. Verhelst, Auteur ; Camilla A. Hinde, Auteur ; Ben C. Sheldon, AuteurThe provision of wild birds with supplementary food has increased substantially over recent decades. While it is assumed that provisioning birds is beneficial, supplementary feeding can have detrimental carry-over' effects on reproductive traits[...]
Article
Shelly Lachish, Auteur ; Sarah C. L. Knowles, Auteur ; Ricardo Alves, Auteur ; Matthew J. Wood, Auteur ; Ben C. Sheldon, Auteur1. Investigating the ecological context in which host-parasite interactions occur and the roles of biotic and abiotic factors in forcing infection dynamics is essential to understanding disease transmission, spread and maintenance. 2. Despite th[...]
Article
Miriam Liedvogel, Auteur ; Ben C. Sheldon, AuteurStudies of a range of taxa, including birds, have revealed latitudinal clines in allele length at the conserved Clock locus, a gene with known influences on behaviour and physiology. Such clines might reflect adaptation to seasonal variation, a [...]
Article
Catherine L. Cosgrove, Auteur ; Matthew J. Wood, Auteur ; Karen P. Day, Auteur ; Ben C. Sheldon, AuteurSeasonal variation in environmental conditions is ubiquitous and can affect the spread of infectious diseases. Understanding seasonal patterns of disease incidence can help to identify mechanisms, such as the demography of hosts and vectors, whi[...]
Article
Simon R. Evans, Auteur ; Alex G. R. Summers, Auteur ; Ben C. Sheldon, AuteurPlumage coloration has provided important model systems for research on signal expression. Whilst it had previously been assumed that moulting provided the only mechanism to change plumage coloration, recent studies have shown plumage colours to[...]
Article
Sandra Bouwhuis, Auteur ; Arie J. van Noordwijk, Auteur ; Ben C. Sheldon, Auteur ; Simon Verhulst, Auteur ; Marcel E. Visser, AuteurThe process of ageing was long thought to be too infrequent to affect life-histories in natural populations. Long-term studies have, however, recently demonstrated ageing to be ubiquitous even in the wild, although confounding factors, such as e[...]
Article
Teddy A. Wilkin, Auteur ; Christopher M. Perrins, Auteur ; Ben C. Sheldon, AuteurDans Ibis (149 NOV 2007)Finding the most biologically meaningful scale at which to describe environmental variation is a persistent problem in ecology. Most studies of forest passerines are conducted at the scale of the habitat or woodland and do not account for enviro[...]
