Ecological immunology: costly parasite defences and trade-offs in evolutionary ecology.
Viewing an individual's immune response to parasites as being subject to optimization in the face of other demands offers potential insights into mechanisms of life history trade-offs, sexual selection, parasite-mediated selection and population dynamics. Expand
A quantitative review of heterozygosity–fitness correlations in animal populations
It is shown that HFC studies do not generally reveal patterns predicted by population genetic theory, and are of small effect, and future studies should use more genetic marker data and utilize sampling designs that shed more light on the biological mechanisms that may modulate the strength of association. Expand
Adaptive Phenotypic Plasticity in Response to Climate Change in a Wild Bird Population
Using a 47-year population study of the great tit in the United Kingdom, it is shown that individual adjustment of behavior in response to the environment has enabled the population to track a rapidly changing environment very closely. Expand
Ultraviolet colour variation influences blue tit sex ratios
Experimental evidence that females skew the sex ratio of their offspring in response to the ultraviolet plumage ornamentation of their mates is reported, suggesting that chromosomal sex determination may not constrain the sex ratios of multiparous vertebrates. Expand
Genetic architecture of fitness and nonfitness traits: empirical patterns and development of ideas
Comparative studies of dominance contributions for different types of traits, together with theoretical predictions and a large body of indirect evidence, suggest an important role of dominance variance in determining levels of residual variance for fitness-traits. Expand
Overlapping community detection using Bayesian non-negative matrix factorization.
This work presents a probabilistic approach to community detection that utilizes a Bayesian non-negative matrix factorization model to extract overlapping modules from a network. Expand
Constraints in the Evolution of Sex Ratio Adjustment
This work uses meta-analysis to test the role of two constraints in the evolution of sex ratios in birds and wasps and shows that mechanisms of sex determination do not necessarily constrain the Evolution of sex ratio adjustment, and parental ability to predict their offsprings' environment influences the evolutionof sex ratio patterns across taxa.

Severe inbreeding depression in collared flycatchers (Ficedula albicollis)
The results illustrate how severe inbreeding depression and considerable genetic load may exist in natural populations, but detecting them may require extensive long–term datasets. Expand
Male phenotype, fertility, and the pursuit of extra-pair copulations by female birds

A simple model is described, in which functional fertility (the success of ejaculates in fertilizing eggs) covaries with male phenotype, which can explain the observed associations equally well and several alternative approaches are discussed which may allow their resolution. Expand
Lifetime Reproductive Success and Heritability in Nature
Analysis of a large data set from the collared flycatcher Ficedula albicollis confirmed a previous finding that traits closely associated with fitness tend to have lower heritability, but analysis of coefficients of additive genetic variation revealed that trait’s association with fitness was not due to lower levels of VA but was due to their higher residual variance.
