Challenges in monitoring rare and elusive species often involve low detection and sampling success. Noninvasive methods have allowed researchers to more efficiently monitor rare and elusive species while reducing costs of more invasive, traditional techniques. We evaluated the use of a noninvasive method as an alternative to live‐trapping pocket gophers. We found that tunnel diameter can be used to help distinguish between occupancy by the Wyoming pocket gopher (Thomomys clusius; a species of conservation concern) and its more abundant and widespread congener, the northern pocket gopher (T. talpoides). Our method reduces reliance on more invasive methods of monitoring occupancy (i.e., live‐ or kill‐trapping) for co‐occurring pocket gopher species, and likely can be extended to survey for other species of fossorial mammals. © 2020 The Wildlife Society.

隧道直径作为检测袋鼠(Geomyidae)占用率的一种非侵入性方法
监测稀有和难以捉摸的物种的挑战通常涉及较低的检测和采样成功率。非侵入性方法使研究人员能够更有效地监视稀有和难以捉摸的物种,同时降低更具侵入性的传统技术的成本。我们评估了使用无创方法替代活捕袋鼠的方法。我们发现,隧道直径可用于区分怀俄明州袋鼠(Thomomys clusius;一种有保护意义的物种)及其更丰富和广泛的同类物北部袋鼠(T. talpoides))。我们的方法减少了对同时发生的袖珍地鼠物种的居住情况监测(即活捕或杀害诱捕)的更具侵入性的方法的依赖,并且可能会扩展到调查其他种类的人工哺乳动物。©2020野生动物协会。
