当雄性为其配偶提供抚养后代的帮助以及获得保护的资源时，雌性配偶的选择应该受到雄性表型和资源质量的影响。相比之下，在没有父系照顾的情况下，男性和领地特征选择的相对重要性就不那么为人所知了。我们观察了雌性在雄性领地的分布，以评估puku Kobus vardoni和topi Damaliscus luatus的择偶标准，这两种羚羊雄性保护资源，但不参与父母的照顾。在这两个物种中，雌性分布与雄性表型以及不同地区的饲料质量和捕食风险有关。雄性和领地特征是相互关联的，但统计分析表明，雄性特征、饲料质量和捕食风险都是两个研究物种雌性选择的显著独立预测因子。这是首次证明雌性哺乳动物的选择可能同时受到雄性表型和防御资源质量的影响。
Where males offer their mates assistance in rearing offspring as well as access to defended resources, female mate choice should be influenced by both male phenotype and resource quality. In contrast, where there is no paternal care the relative importance of choice for male and territory traits is less well understood. We looked at female distribution across male territories in order to assess mate choice criteria in puku Kobus vardoni, and topi Damaliscus lunatus, two antelope where males defend resources but are not involved in parental care. In both species female distribution was correlated with male phenotype as well as the quality of forage and risk of predation on different territories. Male and territory characteristics were intercorrelated, but statistical analysis revealed that male traits, forage quality and predation risk were all significant, independent predictors of female choice in both study species. This is the first demonstration that female choice in mammals might be simultaneously influenced by male phenotype as well as the quality of defended resources.
