Lek是一群雄性领地，雌性只在交配时访问;这是哺乳动物中相当罕见的交配系统。由于我们想调查过去的男性交配成功的作用，他们的忠诚列克领土，我们流离失所的休耕鹿女性的列克（列克A），即我们删除了发情男性的资源。他们搬到一个新的地区，随后一些领土的男性（“移动”男性），他们建立了一个新的列克（列克B）。其他雄性（“忠实”雄性）留在Lek A。前者有较低的交配成功率和优势排名的早期，不受干扰的部分车辙。干扰后，Lek B上的忠诚雄虫的MS明显降低，而移动的雄虫的MS高于Lek A上的MS。然后我们打扰了Lek B。雌性回到Lek A，忠诚雄性的交配成功率恢复到原来的水平。过去的交配成功是预测雄性是否忠诚或移动的的主要因素。我们第一次说明了过去的经验，在促进列克保真度的重要性，这个实验提供了一个深入了解的机制，导致传统的使用列克。
A lek is a clump of male territories that females visit only for mating; it is quite a rare mating system among mammals. As we wanted to investigate the role of past male mating success on their fidelity to lek territories, we displaced fallow deer females by a lek (Lek A), i.e. we removed the resources for rutting males. They moved to a new area followed by some of the territorial males (‘mobile’ males) where they established a new lek (Lek B). Other males (‘faithful’ males) stayed on Lek A. The former had lower mating success and dominance ranking in the early, undisturbed part of the rut. After disturbance, the MS of faithful males was much reduced, while that of mobile males was higher on Lek B than it had been on Lek A. We then disturbed Lek B. Females returned to Lek A, and the mating success of faithful males reverted to its original level. Past mating success was the main factor predicting whether a male was faithful or mobile. We illustrated for the first time the importance of past experience in promoting lek fidelity; this experiment gives an insight into the mechanisms leading to the traditional use of leks.
