Abstract:

Objective Plateau zokor Myospalax baileyi is one of the dominant pests in the alpine meadow of Qinghai-Tibet Plateau. M. baileyi dwells underground, therefore it is difficult to conduct ecological studies on this species due to limited access to their habitats. Radio tracking is a new technique for the ecological study on small rodents, but is rarely utilized in the studies on M. baileyi populations. The performance of three types of radio transmitters are evaluated in the field and reported in this paper. Methods The radio transmitters manufactured by three companies, Biotrack (Great Britain), Sirtrack (New Zealand) and Telenax (Mexico), were tested for the transmitting depth, transmitting distance, and frequency range of the signals, as well as the adaptability of M. baileyi to the attachment of radio transmitters. Results The radio transmitter manufactured by Biotrack outperformed the other two counterparts. It was attached to M. baileyi for more than 3 months; the radio signals were able to be tracked at a horizontal distance of 50 m, with a signal intensity of 25.00; the transmitter signals were detectable at an underground depth of 2.5 m, with a signal attenuation of 76.74%. The other two types of radio transmitters had no detectable signals at this depth. Conclusion Selecting and properly attaching high-performance radio transmitter enables radio-tracking technique to be used for the ecological studies on M. baileyi, which can be adapted for the similar studies on other subterranean rodents.

摘要:

目的 高原鼢鼠是青藏高原高寒草甸区优势危害鼠种之一,但由于栖息于地下,使其研究手段受到限制,进而影响到高原鼢鼠的基础研究。无线电追踪技术是目前用于小型啮齿动物生态学研究的一项新技术,但目前很少用于高原鼢鼠种群生态学研究,为此将该项技术进行效果测试。方法 选取英国Biotrack、新西兰Sirtrack和墨西哥Telenax 3家公司所产的无线发射器,通过测定其无线信号的发射深度、发射距离、频率范围以及高原鼢鼠对佩戴方式的适应性等指标,对其进行综合评价。结果 英国Biotrack公司所产的无线发射器性能优异,地下目标动物佩戴时间长达3个月以上。水平测试中,信号追踪距离达到50 m,信号强度为25.00。深度测试中,在地下2.5 m处仍能追踪到发射器信号,信号衰减程度为76.74%。其他2种发射器在该深度均无信号。结论 选择性能优异的无线发射器并正确佩戴,无线追踪技术完全可用于高原鼢鼠生态学研究,也可为其他类似地下鼠研究提供参考依据。
