大多数动物将它们的运动活动限制在熟悉的区域，这导致了家的范围。虽然了解家庭范围的建立和变化是高度相关的基础科学和保护，精确定位的因素，形成动态的家庭范围仍然是一个挑战。显然，家域受到底层地形的影响。景观构成，即，不同土地覆盖类型的比例，最近已被证明会影响家庭范围的大小。然而，明确的空间配置的景观，这是已知的是在空间生态学的核心重要性的因素，是没有考虑到大多数研究。我们量化的景观配置的影响，在多个时空尺度上的夏季家庭范围的大小使用GPS数据从两个行为不同的有蹄类动物物种，红色（马鹿）和鹿皮（Capreolus capreolus），在巴伐利亚森林国家公园，德国。我们发现，景观的空间配置是解释家域大小的主导因素。此外，我们发现，家域的大小和景观配置之间的关系的形状取决于物种的栖息地的要求：而梅花鹿减少他们的家域的大小增加景观斑块，关系是驼峰形的红鹿。我们的结果是强大的，在所有测试的时空尺度。
Most animals restrain their movement activities to familiar areas which leads to home ranges. Although understanding both establishment and shifts of home ranges is highly relevant for basic science and conservation, pinpointing the factors that shape the dynamics of home ranges remains a challenge. Evidently home ranges are influenced by the underlying landscape. Landscape composition, i.e., the fraction of different land cover types, has recently been shown to affect home range size. Yet, the explicit spatial configuration of the landscape, a factor which is known to be of central importance in spatial ecology, is not taken into account by most studies. We quantify the effect of landscape configuration on summer home range sizes across multiple spatio-temporal scales using GPS data from two behaviorally distinct ungulate species, red (Cervus elaphus) and roe deer (Capreolus capreolus), in the Bavarian Forest National Park, Germany. We show that the spatial configuration of the landscape is the dominant factor explaining home range size. Furthermore, we find that the shape of the relationship between home range size and landscape configuration depends on a species' habitat requirements: while roe deer decrease their home range size with increasing landscape patchiness, the relationship is hump-shaped for red deer. Our results are robust at all tested spatio-temporal scales.
