Abstract

Accelerated biodiversity loss has destabilized functional links within and between ecosystems. Species that cross different ecosystems during migration between breeding and nonbreeding sites are particularly sensitive to global change because they are exposed to various, often ecosystem-specific, threats. Because these threats have lethal and nonlethal effects on populations, many migratory species are declining, making this group especially vulnerable to global change. To mitigate their decline, research at a continental and flyway scale is required to adequately monitor changes in the migratory and demographic processes of populations during all parts of the annual cycle. The Motus Wildlife Tracking System (Motus) could provide a solution to data gaps that exist for small, migratory species. Motus is an automated telemetry system for animal tracking that uses a single very-high-frequency radio signal to track tagged individuals. Motus can provide information on movements made by individuals of small migrant species, thereby aiding the understanding of aspects of their migration that could affect demographic parameters. Conservation-focused research opportunities related to Motus include identification of critical stopover sites that support and connect multiple species and insight into migratory decisions in small migrant birds related to environmental stressors, such as artificial light at night. Examples of stopover studies from the existing network that demonstrate its utility include identification of a high-conservation-value stopover area for the blackpoll warbler (Setophaga striata) in the eastern United States. Geographical gaps in the network across the Mediterranean region and across eastern Europe need to be filled to track continent-wide movements. Motus can provide individual-level migration information for a variety of small-bodied taxa, and a drive to expand the network will improve its ability to direct conservation plans for such species.

利用泛欧自动遥测网络绘制以鸟类迁徙路线为重点的保护地图。
生物多样性的加速丧失破坏了生态系统内部和生态系统之间的功能联系。在繁殖地和非繁殖地之间迁徙期间穿越不同生态系统的物种对全球变化特别敏感,因为它们面临各种威胁,通常是生态系统特有的威胁。由于这些威胁对种群有致命和非致命的影响,许多迁徙物种正在减少,使这一群体特别容易受到全球变化的影响。为了减轻它们的减少,需要在大陆和飞行路线范围内进行研究,以充分监测年周期所有部分人口的迁徙和人口过程的变化。Motus野生动物追踪系统(Motus)可以为小型迁徙物种的数据缺口提供解决方案。Motus是一种用于动物追踪的自动遥测系统,它使用一个非常高频的无线电信号来追踪被标记的个体。Motus可以提供关于小型移徙物种个体移动的信息,从而有助于了解其移徙可能影响人口参数的各个方面。与Motus相关的以保护为重点的研究机会包括确定支持和连接多个物种的关键中途停留点,以及了解与环境压力(如夜间人造光)相关的小型候鸟的迁徙决定。来自现有网络的中途停留研究的例子证明了它的效用,包括在美国东部为黑尾莺(Setophaga striata)确定了一个高保护价值的中途停留区。需要填补整个地中海区域和整个东欧网络的地理空白,以跟踪整个大陆的移动情况。Motus可以为多种小体类群提供个体水平的迁徙信息,扩大网络的动力将提高其指导此类物种保护计划的能力。

期刊介绍: Conservation Biology welcomes submissions that address the science and practice of conserving Earth's biological diversity. We encourage submissions that emphasize issues germane to any of Earth''s ecosystems or geographic regions and that apply diverse approaches to analyses and problem solving. Nevertheless, manuscripts with relevance to conservation that transcend the particular ecosystem, species, or situation described will be prioritized for publication.
