在西班牙多纳纳国家公园，雄性马鹿在雌性觅食活动中造访的地方保卫交配领土。为了调查雌性是被雄性吸引还是被吸引到地点，领地被围栏围住，这样领地的雄性必须在不同的地点保卫新的领地。在所有情况下，雄性在移动后吸引雌性的数量都较少。在对照实验中，(1)未被操纵的领地没有以同样的方式失去雌性，(2)当栅栏被拆除时，所有的雄性都找回了一些丢失的雌性，(3)领地雄性在实验中被转移到更好的饲料区时获得了雌性。确定了两种类型的领土：一种是有好的白狼的领土，另一种是女性交通路线上的领土。与雄性吸引假说下的预测相反，实验操作后雌性数量的减少越大，以前使用该区域的雌性越多。在那些划定了良好沼泽的地区，草的质量预测了雄性迁出这个地点后失去雌性的数量和比例。结果表明，多纳纳马鹿的领地是一种资源防御系统，雄性马鹿的成功很大程度上取决于其领地的位置。(C)1995年动物行为研究协会
Male red deer, Cervus elaphus, in Donana National Park (Spain) defend mating territories at places that females visit during their foraging movements. To investigate whether females were attracted to males or to sites, territories were fenced so that the territorial males had to defend a new territory at a different site. In all cases, males attracted fewer females after they had moved. In control experiments, (1) unmanipulated territories did not lose females in the same way, (2) when the fence was removed, all males recovered some of the lost females, and (3) territorial males gained females when they were experimentally moved to better forage areas. Two kinds of territories were identified: those containing good swards and those at routes of female traffic. Contrary to predictions under the male-attraction hypothesis, the decrease in number of females after the experimental manipulation was greater the more females formerly used that territory. In those territories delimiting good swards, the quality of grass predicted both the number and the proportion of females lost after the male was moved from this site. The results demonstrate that territoriality of red deer in Donana is a resource-defence system, where the success of a male largely depends on the location of his territory.
