Recension (övrigt vetenskapligt/konstnärligt)abstract
- The recent development of simple, DNA-based methods for the determination of an individual's sex will make possible large-scale studies of sex allocation and the consequence of gender in birds. Birds provide ideal systems for studying these questions in v

- When the relative fitness of sons and daughters differs, sex-allocation theory predicts that it would be adaptive for individuals to adjust their investment in different sexes of offspring. Sex ratio adjustment by females in response to the sexual attract

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In many vertebrates, males are apparently more affected by adverse environmental conditions, particularly during early stages of development, than are females. Three explanations have been proposed for this pattern. First, sexual size dimorphism (SSD) may

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Sex allocation theory, when combined with 'genetic benefit' models of female choice, predicts that it would be adaptive for female birds to bias the sex ratio of extra-pair offspring in favour of males. We tested this prediction for a population of collar

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The way that variation in paternity affects the optimal level of paternal effort has been a contentious issue, both in terms of theory and the empirical data needed to test competing theories. Clarification of the theoretical issues has led to the predict

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Whether females can obtain genetic benefits from mate choice is contentious, and the main problem faced by previous studies of natural populations is that many factors other than paternal genes contribute to offspring fitness. Here, we use comparisons bet

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Extrapair paternity has been suggested to represent a potentially important source of sexual selection on male secondary sexual characters, particularly in birds with predominantly socially monogamous mating systems. However, relatively few studies have d
