Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In the ruff, there are two alternative male reproductive strategies. The majority of males of this lekking bird attempt to establish and defend territories on leks, and are referred to as Independents. Other males, referred to as Satellites, forego this b

Beauty is in the eye of the beholder: causes and consequences of variation in mating preferences

Recension (övrigt vetenskapligt/konstnärligt)abstract
- To a large extent, the success of evolutionary ecology stems from its focus on individual variation and acknowledging that individuals vary in predictable ways. Sexual selection is probably the branch of evolutionary ecology that has received most interes

Competition for females on leks when male competitive abilities differ: empirical test of a model

Ingår i: BEHAVIORAL ECOLOGY. - : OXFORD UNIV PRESS INC. - 1045-2249. ; 9:5, s. 427-431
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Leks are mating arenas visited by females seeking copulations and can be thought of as patches differing in female encounter rate. Recently, the ideal free distribution model of unequal competitors with interference has been applied to explain male distri

LEK SIZE, MALE MATING SKEW AND THE EVOLUTION OF LEKKING
- 1995
-
Ingår i: NATURE. - : MACMILLAN MAGAZINES LTD. - 0028-0836. ; 373:6510, s. 148-151
-
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

The social implications of traditional use of lek sites in the ruff Philomachus pugnax
- 1997
-
Ingår i: BEHAVIORAL ECOLOGY. - : OXFORD UNIV PRESS INC. - 1045-2249. ; 8:2, s. 211-217
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In almost every lekking vertebrate, adult males use traditional lek sites. This paper attempts to explain this phenomenon by investigating the social implications of traditional use of lek sites. A population of ruffs Philomachus pugnax was observed durin
