摘要：本研究探讨了科罗拉多州博尔德城市和乡村环境中黑尾草原土拨鼠（Cynomys ludovicianus）对人类入侵的行为反应。我们预计，如果土拨鼠习惯了反复的骚扰，随着时间的推移，它们应该允许反复出现的人类入侵者靠近，然后再发出警报或开始隐藏。我们还预测，在表现出回避反应之前，城市群体可能会比农村群体更接近。在 7 个月内，接触了 4 个聚居地（2 个农村和 2 个城市）超过 100 次。草原土拨鼠并没有表现出习惯性，而是表现出隐藏行为的反应性增强，更早地撤回洞穴，并不断出现干扰。吠叫距离并不会随着反复入侵而变化，但随着时间的推移，草原土拨鼠在执行回避反应时吠叫的频率会降低，这一结果对草原土拨鼠的管理具有影响。农村聚居地的初始隐蔽距离较高，并且随着反复入侵，这些距离比城市聚居地的隐蔽距离增加得更快。因此，农村土拨鼠可能比城市土拨鼠对人类入侵更敏感。
Abstract This study addressed behavioral responses by black-tailed prairie dogs (Cynomys ludovicianus) to human intrusion in urban and rural environments in Boulder, Colorado. We expected that if prairie dogs habituate to repeated disturbances, they should allow a recurring human intruder to approach closer over time before sounding an alarm bark or initiating concealment. We also predicted that urban colonies could be approached more closely than rural colonies before displaying an avoidance response. Four colonies (2 rural and 2 urban) were approached >100 times over a 7-month period. Rather than exhibiting habituation, prairie dogs demonstrated increased responsiveness in concealment behavior, retreating to their burrows earlier, with recurring disturbances. Barking distances did not change consistently with repeated intrusion, but, over time, prairie dogs barked less frequently when performing their avoidance response, a result with implications for prairie dog management. Rural colonies had higher initial concealment distances, and these distances increased more rapidly with repeated intrusion than did concealment distances in urban colonies. Thus, rural prairie dogs may be more sensitive to human intrusion than urban prairie dogs.
