Unusually dynamic sex roles in a fish
- E. Forsgren, T. Amundsen, Å. Borg, J. Bjelvenmark

- Nature
- 3 June 2004
Sex roles are typically thought of as being fixed for a given species. In most animals males compete for females, whereas the females are more reluctant to mate. Therefore sexual selection usually… Expand
Male mate choice selects for female coloration in a fish
- T. Amundsen, E. Forsgren
- Biology, Medicine
- Proceedings of the National Academy of Sciences…
- 16 October 2001
Although sexual selection theory has proved successful in explaining a wide array of male ornaments, the function of ornaments occurring in females is largely unknown. Traditionally, female ornaments… Expand
Ultraviolet colour vision and ornamentation in bluethroats
- S. Andersson, T. Amundsen
- Biology
- Proceedings of the Royal Society of London…
- 22 November 1997
Many birds see in the ultraviolet (300–400 nm), but there is limited evidence for colour communication (signalling by spectral shape independently of brightness) in this ‘hidden’ waveband. Such data… Expand
Paternity and paternity assurance behaviour in the bluethroat,Luscinias.svecica

Abstract Genetic parentage was examined in the territorial and predominantly monogamous bluethroat, by means of multilocus DNA fingerprinting. Thirty-five per cent (11/31) of nests contained one or… Expand
On the function of female ornaments: male bluethroats prefer colourful females
- T. Amundsen, E. Forsgren, L. T. Hansen
- Biology
- Proceedings of the Royal Society of London…
- 22 November 1997
Female ornaments in animals with conventional sex roles have traditionally been considered non–functional, being merely a genetically correlated response to selection for male ornamentation.… Expand
Female Ornaments: Genetically Correlated or Sexually Selected?
- T. Amundsen
- Biology
- 2000
Studies of sexual selection have so far focussed almost solely on males, and have been highly successful in explaining their often extravagant adornments. However, females of a variety of animal… Expand

Egg size and parental quality influence nestling growth in the Shag

Seasonal change in female choice for male size in the two-spotted goby
- Å. Borg, E. Forsgren, T. Amundsen
- Biology
- Animal Behaviour
- 1 October 2006
Mate choice may vary according to various factors, such as mate availability and variation in mate quality. We tested seasonal changes in female choice regarding male size in a marine fish, the… Expand
Effects of egg size and parental quality on early nestling growth: An experiment with the Antarctic petrel
- T. Amundsen, Svein-Håkon Lorentsen, T. Tveraa
- Biology
- 1 September 1996
A large number of studies have reported a positive relationship between the egg size of birds and the subsequent growth and/or survival of nestlings, but such effects may partly be due to confounding… Expand
