Positive sexual imprinting is a process by which individuals use the phenotype of their
opposite-sex parent as a template for choosing mates and is suggested to play an important …

Research on mate choice has primarily focused on preferences for quality indicators,
assuming that all individuals show consensus about who is the most attractive. However, in …

In many species that form socially monogamous pair bonds, a considerable proportion of the
offspring is sired by extrapair males. This observation has remained a puzzle for …

Human mate choice is central to individuals' lives and to the evolution of the species, but the
basis of variation in mate choice is not well understood. Here we looked at a large …

Phenotypic variance results from variation in biological information possessed by
individuals. Quantitative geneticists often strive to partition out all environmental variance to …

A major challenge in behavioural and evolutionary ecology is to understand the evolution
and maintenance of consistent behavioural differences among individuals within …

The classical version of the differential allocation hypothesis states that, when females
reproduce over their lifetime with partners that differ in their genetic quality, they should …

In spite of attracting significant attention as a model for song learning, sexual imprinting and
mate-choice, there has been surprisingly little research on the general cognitive abilities of …

Positive sexual imprinting is a process by which individuals use the phenotype of their
opposite-sex parent as a template for acquiring mates. Recent studies in humans have …

Consistent between-individual differences in context-general behavioral traits (often called
personality traits) are particularly interesting for behavioral ecologists because they might …
