Manipulating lek size and composition using decoys: an experimental investigation of lek evolution models.

Abstract excerpt

Four theoretical models have been proposed to account for the origin and maintenance of leks: hotspot, female preference, hotshot, and black hole models. Each has been validated in particular cases, and most are not mutually exclusive; therefore, it has been difficult to contrast and separate them, empirically and experimentally.
