...(2) Quantitative genetics In addition to the strength and nature of selection, the level of any evolutionary response also depends on the narrow-sense heritability (Falconer & Mackay, 1996)....

...…to estimate heritability in populations, including parent–offspring regressions and brood swaps, all of which are described extensively elsewhere (Falconer & Mackay, 1996; Roff, 1997; Lynch & Walsh, 1998; Ellegren & Sheldon, 2008; Charmantier, Garant & Kruuk, 2014), but it is perhaps the animal…...

...The narrow-sense heritability multiplied by the standardised selection differential is known as the breeder’s equation and provides an estimate of the response to selection (Falconer & Mackay, 1996)....

...It has been known for a long time that behaviour in psychological tests is not only determined by the cognitive capacities of individuals, but also by motor and perceptual abilities, motivational state, and personality traits (Yerkes & Dodson, 1908; Bitterman, 1965; Kamil, 1987)....

...Not only does correlational selection represent a form of non-linear selection, in general selection rarely acts on traits in isolation (Lande & Arnold, 1983; Phillips & Arnold, 1989; Roff, 1992; Schluter & Nychka, 1994) and therefore correlational selection is likely to be a major if not the main…...

...Multivariate selection analysis can be achieved simply by regressing relative fitness on multiple (n) standardised phenotypes in the same model, the resulting parameters from which represent partial ‘selection gradients’ for each trait (Lande & Arnold, 1983)....

...The development of a simple statistical framework for estimating selection on quantitative traits (Lande & Arnold, 1983; Phillips & Arnold, 1989) was instrumental in evolutionary ecology....

...The formal Lande & Arnold (1983) way to present non-linear selection results is in a matrix (called γ ) of the standardised quadratic and correlational coefficients (from one multiple regression with relative fitness against standardised traits, their squared terms, and their interactions) with the…...

...A major challenge in evolutionary biology generally is to account for these other correlated traits (Lande & Arnold, 1983; Phillips & Arnold, 1989); this is perhaps readily appreciated in the context of cognitive and personality traits, which by definition should be linked to multiple behavioural…...
