Increased attention to species movement in response to environmental change highlights the need to consider changes in species distributions and altered biological assemblages. Such changes are well known from paleoecological studies, but have accelerated with ongoing pervasive human influence. In addition to species that move, some species will stay put, leading to an array of novel interactions. Species show a variety of responses that can allow movement or persistence. Conservation and restoration actions have traditionally focused on maintaining or returning species in particular places, but increasingly also include interventions that facilitate movement. Approaches are required that incorporate the fluidity of biotic assemblages into the goals set and interventions deployed.

人们越来越关注物种对环境变化的响应，这凸显了需要考虑物种分布的变化和生物组成的改变。这些变化在古生态学研究中是众所周知的，但是随着人类的不断普及而加速了。除了移动的物种外，某些物种还将保留下来，从而导致一系列新颖的相互作用。物种显示出各种可能允许移动或持续存在的反应。传统上，保护和恢复行动的重点是在特定地方维持或归还物种，但越来越多地包括促进迁徙的干预措施。需要采取各种措施，将生物活动的流动性纳入目标设定和干预措施中。
