It is proposed that consistent behavioural differences among individuals, or personality, covary with life history and physiological differences at the within-population, interpopulation and interspecific levels.
The multifarious effects of dispersal and gene flow on contemporary adaptation
It is suggested that an intermediate level of gene flow will allow the greatest adaptive divergence, owing to genetic/demographic rescue and ‘reinforcement’ and once a certain level of dispersal is reached, it is predicted that a further increase may have negative effects on adaptive divergence.
Environmental quality and evolutionary potential: lessons from wild populations
A meta-analysis on recent studies comparing heritability in favourable versus unfavourable conditions in non-domestic and non-laboratory animals provides evidence for increased heritabilityIn more favourable conditions, significantly so for morphometric traits but not for traits more closely related to fitness.

This special feature about ‘eco-evolutionary dynamics’ brings together biologists from empirical and theoretical backgrounds to bridge the gap between ecology and evolution and provide a series of contributions aimed at quantifying the interactions between these fundamental processes.

It is found that Atlantic salmon choose their mates in order to increase the heterozygosity of their offspring at the MHC and, more specifically, at the peptide–binding region, presumably inorder to provide them with better defence against parasites and pathogens.
Ecological determinants and temporal stability of the within‐river population structure in Atlantic salmon (Salmo salar L.) *
It is concluded that the combined use of both models may offer a promising avenue for studies aiming to understand the dynamics of genetic structure of species found in unstable environments.
A genetic evaluation of mating system and determinants of individual reproductive success in Atlantic salmon (Salmo salar L.).
The results indicate that this species' mating system is more flexible than previously thought and suggest that factors such as potential genetic benefits or environmental uncertainty may also be driving the evolution and the plasticity of mating systems in Atlantic salmon.
Evolution driven by differential dispersal within a wild bird population

The evolution of differences in body mass within a population of great tits, Parus major, inhabiting a single continuous woodland, over a 36-year period is document, showing that genetic variance for nestling body mass is spatially variable, and that this diversifying effect is reinforced by non-random dispersal.
Heritability of life‐history tactics and genetic correlation with body size in a natural population of brook charr (Salvelinus fontinalis)

This study is one of the very few to have successfully used sibship‐reconstruction to estimate quantitative genetic parameters under wild conditions and indicates that life‐history tactics in this population have the potential to evolve in response to selection acting on the tactic itself or indirectly via selection on body size.
The Misuse of BLUP in Ecology and Evolution

- 18 November 2009
Analytically and through simulation and example why BLUP often gives anticonservative and biased estimates of evolutionary and ecological parameters is shown and how unbiased and powerful tests can be derived that adequately quantify uncertainty are shown.
