Abstract Data from animals equipped with global positioning system collars have advanced our understanding of vertebrates, but this technology has rarely been employed to study feral equids. Hesitation to equip feral equids with telemetry collars in the USA can often be attributed to safety concerns stemming from one study from the 1980s, where injuries were sustained by feral horses (Equus ferus caballus) equipped with radio-collars. Improvements in collar design over the ensuing quarter-century may have decreased risk of collar-related complications; however, telemetry-based studies on feral equids continue to be limited. In the present review, studies from wild and feral equids worldwide were systematically reviewed to better understand the mortality and injury risk in application of telemetry collars to equids. Our goals were to: (1) report the number of individual equids fitted with telemetry collars (1979–2017); and (2) document the number of individual equids that reportedly died or suffered injuries from collars or other sources. A comparative review of elk (Cervus canadensis), mule deer (Odocoileus hemionus) and pronghorn (Antilocapra americana) was also conducted to evaluate the relative risk of collar-related complications among equids and routinely collared North American ungulates. In total, 1089 wild and feral telemetered equids were identified across 48 studies. Of these, 87 (8.0%) were reported to have died, with only one (0.09%) mortality attributable to a collar. Comparatively, 23.0% (1095) of 4761 elk, mule deer and pronghorn fitted with telemetry collars were found to have died in the same number of studies, though no mortalities were reported to be related to the collar. Although wild and feral equids did not experience increased natural mortality compared with the other ungulates, studies have not provided sufficient information to assess relative risk of collar-related complications. Explicit reporting and discussion of telemetry collar impacts in future publications of all animal species are recommended, especially equids, to improve understanding of how telemetry collars can affect study individuals.

马匹和遥测项圈的系统审查:对部署和报告的影响

摘要 来自配备全球定位系统项圈的动物数据促进了我们对脊椎动物的理解,但这项技术很少用于研究野生马科动物。在美国,对为野马配备遥测项圈的犹豫通常可归因于 1980 年代一项研究中的安全问题,当时配备无线电项圈的野马(Equus ferus caballus)受伤。在接下来的四分之一个世纪里,衣领设计的改进可能降低了衣领相关并发症的风险;然而,基于遥测的野生马科动物研究仍然有限。在本综述中,系统地审查了世界范围内野生和野生马科动物的研究,以更好地了解将遥测项圈应用于马科动物的死亡率和伤害风险。我们的目标是:(1) 报告装有遥测项圈的个体马科动物的数量(1979-2017);(2) 记录据报道因项圈或其他原因死亡或受伤的个体马科动物的数量。还对麋鹿 (Cervus canadensis)、骡鹿 (Odocoileus hemionus) 和叉角羚 (Antilocapra americana) 进行了比较审查,以评估马科动物和常规戴项圈的北美有蹄类动物的项圈相关并发症的相对风险。在 48 项研究中,总共确定了 1089 只野生和野生遥测马科动物。其中,据报道有 87 人 (8.0%) 死亡,其中只有 1 人 (0.09%) 死于项圈。相比之下,在相同数量的研究中发现,4761 头麋鹿、长耳鹿和叉角羚中有 23.0% (1095) 头装有遥测项圈,已经死亡,尽管据报道没有与项圈有关的死亡人数。尽管与其他有蹄类动物相比,野生马科动物和野生马科动物的自然死亡率并未增加,但研究并未提供足够的信息来评估项圈相关并发症的相对风险。建议在所有动物物种的未来出版物中明确报告和讨论遥测项圈的影响,尤其是马,以提高对遥测项圈如何影响研究个体的理解。
