All organisms require space in which to live and all are capable, at some point in their life cycle, of moving from one habitat to another. The range of habitats occupied, and dispersal among habitats, determines the geographical range of species and how the sizes of their populations change from place to place and through time. But ecologists are only beginning to learn the rules that animals use to select habitat, how their choice responds to environmental change, and how habitat, and movement among habitats, influences population density.

所有生物都需要生存的空间，在生命周期的某个阶段，所有生物都有能力从一个栖息地迁移到另一个栖息地。 栖息地的范围和栖息地之间的扩散，决定了物种的地理范围，以及它们的种群规模如何随时间和地点而变化。 但生态学家们才刚刚开始了解动物选择栖息地的规则，它们的选择如何对环境变化做出反应，以及栖息地和栖息地之间的运动如何影响种群密度。
