Data from: Increasing temperature, not mean temperature, is a cue for avian timing of reproduction

Sonja Verena Schaper, Alistair S. Dawson, Peter J. Sharp, Phillip Gienapp, Samuel P. Caro, Marcel E. Visser, Sonja V. Schaper & Alistair Dawson
Timing of reproduction in temperate zone birds is strongly correlated with spring temperature, with an earlier onset of breeding in warmer years. Females adjust their laying between years to be synchronized with local food sources and thereby optimize reproductive output. However, climate change currently disrupts the link between predictive environmental cues and spring phenology. To investigate direct effects of temperature on the decision to lay, and its genetic basis, we used pairs of Great Tits...

Data from: Recombination and hitchhiking of deleterious alleles

Matthew Hartfield & Sarah P. Otto
When new advantageous alleles arise and spread within a population, deleterious alleles at neighbouring loci can hitchhike alongside them and spread to fixation in areas of low recombination, introducing a fixed mutation load. We use branching processes and diffusion equations to calculate the probability that a deleterious allele hitchhikes and fixes alongside an advantageous mutant. As expected, the probability of fixation of a deleterious hitchhiker rises with the selective advantage of the sweeping allele and...

Data from: Natural selection on a measure of parasite resistance varies across ages and environmental conditions in a wild mammal

Adam D. Hayward, Alastair J. Wilson, Jill G. Pilkington, Tim H. Clutton-Brock, Josephine M. Pemberton & Loeske E. B. Kruuk
Parasites detrimentally affect host fitness, leading to expectations of positive selection on host parasite resistance. However, since immunity is costly, host fitness may be maximized at low, but non-zero, parasite infection intensities. These hypotheses are rarely tested on natural variation in free-living populations. We investigated selection on a measure of host parasite resistance in a naturally-regulated Soay sheep population using a longitudinal data set, and found negative correlations between parasite infection intensity and annual fitness...

Data from: Fine-scale population structure, inbreeding risk and avoidance in a wild insect population

Amanda Bretman, Rolando Rodríguez-Muñoz, Craig Walling, Jon Slate & Tom Tregenza
The ecological and evolutionary importance of fine scale genetic structure within populations is increasingly appreciated. However, available data are largely restricted to wild vertebrates and eusocial insects. In addition there is the expectation that most insects tend to have such large and high density populations and are so mobile that they are unlikely to face inbreeding risks through fine scale population structuring. This has made the growing body of evidence for inbreeding avoidance in insects...

Data from: Genetic analysis of life-history constraint and evolution in a wild ungulate population

Michael B. Morrissey, Craig A. Walling, Alastair J. Wilson, Josephine M. Pemberton, Tim H. Clutton-Brock & Loeske E. B. Kruuk
Trade-offs among life-history traits are central to evolutionary theory. In quantitative genetic terms, trade-offs may be manifested as negative genetic covariances relative to the direction of selection on phenotypic traits. Although the expression and selection of ecologically important phenotypic variation are fundamentally multivariate phenomena, the in situ quantification of genetic covariances is challenging. Even for life-history traits, where well-developed theory exists with which to relate phenotypic variation to fitness variation, little evidence exists from in...

Data from: NEMBASE4: the nematode transcriptome resource

Mark L. Blaxter, James Wasmuth, Benjamin Elsworth & Mark Blaxter
Nematode parasites are of major importance in human health and agriculture, and free-living species deliver essential ecosystem services. The genomics revolution has resulted in the production of many datasets of expressed sequence tags (ESTs) from a phylogenetically wide range of nematode species, but these are not easily compared. NEMBASE4 presents a single portal onto extensively functionally annotated, EST-derived transcriptomes from over sixty species of nematodes, including plant and animal parasites and free-living taxa. Using the...

Data from: Quantitative genetics of immunity and life history under different photoperiods

Katrin Hammerschmidt, Peter Deines, Alastair J. Wilson, Jens Rolff, K Hammerschmidt, P Deines, J Rolff & A J Wilson
Insects with complex life-cycles should optimize age and size at maturity during larval development. When inhabiting seasonal environments, organisms have limited reproductive periods and face fundamental decisions: individuals that reach maturity late in season have to either reproduce at a small size or increase their growth rates. Increasing growth rates is costly in insects due to higher juvenile mortality, decreased adult survival, or increased susceptibility to parasitism by bacteria and viruses via compromised immune function....
