Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Models of sexual selection usually assume that variation in the expression of sexual ornaments is determined largely by genetic, rather than environmental, factors(1). However, empirical support for this assumption conies from studies of species with litt

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Theories of sexual selection usually assume that female preferences for male ornamental traits are fixed and always likely to favour the largest or most extravagant sexual ornaments. This is not, however, always necessary or likely, particularly in resour

LEK SIZE, MALE MATING SKEW AND THE EVOLUTION OF LEKKING

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- DESPITE extensive theoretical effort(1,8), the evolution of lekking as a mating system remains a controversial issue(9,10). Leks are nonresource-based matins aggregations(2), but may also be regarded as patches differing in female encounter rate(2,3,5,7).

Tidskriftsartikel (refereegranskat)abstract
- Lek size varies greatly among lekking species. At present there is no explicit theoretical explanation for this diversity. We extend an existing model of optimal lek size that incorporates female mating preferences and male-male contest competition. The m
