传统交配地(LEK)上聚集的雄性之间交配成功率的显著差异通常被认为是雄性表型1-6的雌性选择的证据，但雌性有蹄类动物似乎更喜欢特定的区域6-12，即使没有其他个体在LEK 11，12上。雌性对区域的选择可能受到空间特征7-10，12的影响，但观察表明，雌性也可能被土壤13中的嗅觉线索吸引到成功的区域。在这里，我们报道了在两个红斑羚羊物种的LEK上成功和不成功的区域之间转移表土，导致在不成功的区域上的雌性和交配的数量增加了10倍。雌性可能是被其他雌性大量使用而积累的气味吸引到土壤中的。由于这种吸引力，随机过程可能在领地持有者之间交配成功的差异中发挥重要作用。
PRONOUNCED differences in mating success between males holding territories clustered on traditional mating grounds (leks) are commonly cited as evidence of female choice for male phenotypes 1-6, but female ungulates appear to prefer particular territories 6-12 even when no other individuals are on the lek 11,12. Female choice of territories may be influenced by spatial features 7-10,12, but observations suggest that females may also be attracted to successful territories by olfactory cues in the soil 13. Here we report that transferring the topsoil between successful and unsuccessful territories on leks of two reduncine antelope species caused the numbers of females and matings on the unsuccessful territories to increase tenfold. Females were probably attracted to the soil by smells that had accumulated from heavy use by other females. Because of this attraction, stochastic process may play an important part in generating the variance in mating success between territory holders on leks.
