Given that males and females defend separate feeding territories, the competitive advantage of large individuals in the experiment suggests that contest competition selects for large body size in both sexes.
The competitive regime of P. pallescens includes strong within-group scramble and contest competition [Schülke, 2003].
IC is divided into two components, contest competition and scramble competition [9].
We discuss these results in relation to the role of male contest competition in the evolution of multiple male signals and sexual dimorphism in dwarf chameleons.
Here I consider the implications of the two formulations under two broad ecological scenarios: scramble competition for an equally divided resource (e.g. food) and contest competition for an unequally divided resource (e.g. nest sites).
The two-dimensionality of the human mating environment, along with phylogeny, the spatial and temporal clustering of mates and competitors, and anatomical considerations, predict that contest competition should have been the primary mechanism of sexual selection in men.
Men's traits are better designed for contest competition than for other sexual selection mechanisms; size, muscularity, strength, aggression, and the manufacture and use of weapons probably helped ancestral males win contests directly, and deep voices and facial hair signal dominance more effectively than they increase attractiveness.
I am looking forward hearing today's Chris Austin Songwriting Contest winners and tomorrow's lineup for the second annual MerleFest Band Contest Competition.
Note that γ = 0 is the case of pure scramble competition while it has been argued [60] that contest competition requires γ>1.
Males can engage in both contest competition via physical/ritualized fighting and outbidding competition, in which a male plays off rivals by making a better offer [4].
The short-term processes leading to exploitative competition are often referred to as scramble competition [118] while interference competition is also referred to as contest competition (e.g. see [119]).
