当前环境的变化和对野生动物威胁的增加促使人们需要更好地了解物种的保护要求。保护具有大活动范围的大型动物物种的战略包括建立大型保护区，或为迁徙动物建立受保护的繁殖区、停留区和越冬区。我们的目的是描述安第斯秃鹰（Vulturgryphus）的运动行为，并将其与该物种及其环境保护的意义联系起来。我们研究了目前的保护策略是否足以确保该物种的日常需求，并评估了保护区覆盖繁殖和觅食区域的程度。我们提出了一个新的挑战，即大型物种的保护，这些物种每天都在进行长距离的运动，跨越了许多政治和生态边界。安地斯秃鹰身上装有gps卫星发射机，每天从繁殖地（阿根廷和智利的山区）飞到觅食地（阿根廷的大草原），飞越安第斯山脉。这些飞行表明，目前的保护策略不足以保护这种每日移动模式的物种，需要新的方法。因此，有必要通过个体层面的方法，整合塑造运动模式的内在（繁殖和觅食行为）和外在（政治和地貌边界）因素，对这些生物的运动生态学有更深入的了解。保护工作必须包括国际合作，旨在将保护旗舰物种、管理公共和私人土地以及维护宝贵的生态系统服务结合起来。(C) 2014 Elsevier Ltd.版权所有。
Current changes in the environment and increases in threats to wildlife have prompted the need for a better understanding of species' conservation requirements. Strategies for the conservation of large-sized animal species with large home ranges have included the creation of large protected areas, or for migrants, the creation of protected breeding, stop-over and wintering areas. We aim to describe the movement behaviour of Andean condors (Vulturgryphus), and to relate it to its significance in the conservation of this species and its environment. We examine whether current conservation strategies are sufficient to ensure the daily requirements of the species, and evaluate the degree to which breeding and foraging areas are covered by protected areas. We present as a new challenge the conservation of large-sized species that perform daily long-range movements across a number of political and ecological borders. Andean condors tagged with GPS-satellite transmitters make long daily flights from their breeding areas (mountains in Argentina and Chile) to their feeding areas (the steppe in Argentina) crossing over the Andean Cordillera. These flights demonstrate that current conservation strategies are insufficient to protect species with such daily movement patterns, and that new approaches are needed. Thus, it is necessary to gain a more in-depth knowledge of the movement ecology of these organisms through individual-level approaches integrating intrinsic (reproductive and foraging behaviour) and extrinsic (political and geomorphological boundaries) factors that shape movement patterns. Conservation efforts must include international cooperation aiming to combine the conservation of flagship species, the management of public and private lands, and the maintenance of valuable ecosystem services.
