Human-induced disturbances of the environment are rapid and often unpredictable in space and time, exposing wildlife to strong selection pressure favouring plasticity in specific traits. Measuring wildlife behavioural plasticity in response to human-induced disturbances such as hunting pressures is crucial in understanding population expansion in the highly plastic wild boar species. We collected GPS-based movement data from 55 wild boars during drive hunts over three hunting seasons (2019-2022) in the Czech Republic and Sweden to identify behavioural plasticity in space use and movement strategies over a range of experienced hunting disturbances. Daily distance, daily range, and daily range overlap with hunting area were not affected by hunting intensity but were clearly related to wild boar hunting experience. On average, the post-hunt flight distance was 1.80 km, and the flight duration lasted 25.8 h until they returned to their previous ranging area. We detected no relationship in flight behaviour to hunting intensity or wild boar experience. Wild boar monitored in our study showed two behavioural responses to drive hunts, "remain" or "leave". Wild boars tended to "leave" more often with increasing hunting experience. Overall, this study highlights the behavioural plasticity of wild boar in response to drive hunts.
人为干扰环境在空间和时间上迅速且往往不可预测,使野生动物面临强烈的选择压力,有利于特定特征的可塑性。测量野生动物对人为干扰(如狩猎压力)的行为可塑性对于理解高度可塑性的野猪物种的种群扩张至关重要。我们在捷克共和国和瑞典的三个狩猎季节(2019-2022 年)期间,通过驱动狩猎收集了 55 头野猪的基于 GPS 的运动数据,以确定在一系列经历的狩猎干扰下,在空间利用和运动策略方面的行为可塑性。每日距离、每日范围和每日范围与狩猎区的重叠不受狩猎强度的影响,但与野猪的狩猎经验明显相关。平均而言,狩猎后的飞行距离为 1.80 公里,飞行持续时间为 25.8 小时,直到它们返回之前的活动范围。我们没有检测到飞行行为与狩猎强度或野猪经验之间的关系。在我们的研究中监测到的野猪表现出对驱动狩猎的两种行为反应,“停留”或“离开”。随着狩猎经验的增加,野猪往往更倾向于“离开”。总的来说,这项研究强调了野猪对驱动狩猎的行为可塑性。
