Female mate preferences for male traits and resource characteristics affect trait evolution and diversification. Here, we test the effects of male body traits and territory characteristics on within-population female preferences and on population–assortative mating in the cichlid Tropheus moorii. Within-population preferences of females were independent of male body size, coloration and territory size but were strongly dependent on territory quality and co-varied with male courtship activity. Courtship activity of individual males was contingent on the quality of their assigned territory, and therefore, courtship may not only indicate intrinsic male quality. On the basis of these results we suggest that female preferences for high-quality territories reinforce the outcome of male–male competition and ensure male mating success. Mating preferences of females for males of their own color variant (ascertained in a previous experiment) were not overturned when males of another color variant were presented in a superior territory, indicating that within- and between-population mate preferences of females depend on different cues.

慈鲷鱼 Tropheus moorii 对雄性特征和领地特征的雌性偏好
女性配偶对男性性状和资源特征的偏好会影响性状进化和多样化。在这里,我们测试了雄性身体特征和领土特征对种群内雌性偏好和慈鲷 Tropheus moorii 种群分类交配的影响。女性的种群内偏好与男性的体型、颜色和领地大小无关,但强烈依赖于领地质量,并与男性求爱活动共同变化。个别雄性的求偶活动取决于其指定领地的质量,因此,求偶可能不仅仅表明雄性的内在品质。基于这些结果,我们建议女性对高质量领土的偏好加强了男性与男性竞争的结果并确保男性交配成功。
