项目摘要

Tracking wild animals, such as seabirds, poses substantial logistical difficulties as they often cannot be observed directly, meaning remote tracking technology is integral to the study of natural behaviour. GPS loggers, which store animals' position at fixed time intervals, are one of the most commonly used remote tracking devices. However, they present a significant cost-to-output trade-off. Affordable GPS tags collect data archivally, and so the animal must be recaptured to retrieve the tag its data. They are also limited in memory capacity and battery life, limiting study durations to 2-3 weeks maximum, and their consequentially large size can have significant impacts on normal behaviour for many species. More expensive devices overcome these problems by remotely communicating with satellites to download data to a server, but can cost hundreds or thousands of pounds per tag, limiting the number of individuals that can be tracked at once.Reverse GPS technology overcomes many of these limitations. Under this system, small, radio frequency-emitting tags are attached to animals, which communicate with nearby receiver stations to estimate and download the location of the tagged animal. These tags are very lightweight, not limited by memory, and have very low power consumption, and so can be used to tag many individuals at once, for long durations, and at a low cost. The ATLAS Wildlife Tracking System is a revolutionary reverse GPS system that has been used on a variety of study systems across the globe to remotely track many individuals simultaneously. We propose to install the first ATLAS system in the Arctic, and conduct a proof-of-concept test of its operationality. During this project, we will establish an ATLAS network of 6 base stations, giving coverage of a 26km2 area, encapsulating a kittiwake study colony and a large fraction of the Bijleveld fjord, at the base of which lies the Nordenskjöld Glacier. This glacier is an important foraging site, but is vulnerable to many of the effects of climate change in the Arctic, including sea surface temperature rises and Atlantification (whereby warmer and saltier water extends into the Arctic ocean, altering prey availability). We will fit 200 kittiwakes with tags, a substantial fraction of the colony, to examine to what extent environmental conditions reduce or exacerbate competition in the area, and how individuals respond. Once optimised, this system could be rolled out to multiple other species, giving a wholistic overview of movement and interactions in this ecosystem.
追踪海鸟等野生动物造成了很大的后勤困难,因为它们往往无法直接观察,这意味着远程追踪技术是自然行为研究不可或缺的一部分。GPS记录仪以固定的时间间隔存储动物的位置,是最常用的远程跟踪设备之一。然而,它们提出了一个重要的成本-产出权衡。负担得起的GPS标签收集数据存档,所以动物必须重新捕获检索标签的数据。它们的记忆容量和电池寿命也有限,研究时间最多限制在2-3周,因此它们的大尺寸可能对许多物种的正常行为产生重大影响。更昂贵的设备通过与卫星远程通信将数据下载到服务器来克服这些问题,但每个标签的成本可能高达数百或数千英镑,限制了可以同时跟踪的个人数量。反向GPS技术克服了其中的许多限制。在这个系统中,小的无线电频率发射标签被贴在动物身上,与附近的接收站通信,以估计和下载被贴标签的动物的位置。这些标签非常轻,不受存储器的限制,并且具有非常低的功耗,因此可以用于一次标记许多个体,持续时间长,并且成本低。ATLAS野生动物跟踪系统是一种革命性的反向GPS系统,已用于地球仪的各种研究系统,以同时远程跟踪许多个体。我们建议在北极安装第一个ATLAS系统,并对其操作性进行概念验证测试。在这个项目中,我们将建立一个由6个基站组成的ATLAS网络,覆盖26平方公里的区域,包括一个三趾鸥研究群体和比耶尔费尔德峡湾的大部分,其底部是Nordenskjöld冰川。这座冰川是一个重要的觅食地,但容易受到北极气候变化的许多影响,包括海面温度上升和海水化(即温暖和咸的海水延伸到北冰洋,改变猎物的可用性)。我们将给200只三趾鸥贴上标签,这是殖民地的很大一部分,以研究环境条件在多大程度上减少或加剧了该地区的竞争,以及个体的反应。一旦优化,该系统可以推广到多个其他物种,从而全面概述该生态系统中的运动和相互作用。
