The Pampas fox (Lycalopex gymnocercus) has suffered from hunting and human persecution for decades, both for fur trade or due to conflicts with livestock. However, studies assessing the effects of hunting pressure on this canid population ecology are lacking. In this work, we assessed the influence of several hunting-related variables on the daily activity patterns and habitat use of the Pampas fox. In private farms of central Argentina, we performed two camera-trapping surveys: one during the non-hunting season and other during the hunting season, distinguishing between sites with or without access by hunters. The habitat use of Pampas foxes did not vary between seasons, but their detectability was lower during the hunting season in habitats that allow humans to see foxes easily (i.e., habitats with high visibility). Pampas foxes selected dusk and night-time, increasing their activity at dusk hours on sites with hunting and showed differences in activity patterns related with the level of visibility of the habitat and to season. Hunting pressure may interact with anthropogenic habitat modifications and create ecological traps for the Pampas fox in agroecosystems.

狩猎对阿根廷中部农业生态系统中潘帕斯狐(Lycalopexgynocercus)的活动模式和栖息地利用的影响有限

该河狐(Lycalopex gymnocercus) 几十年来一直遭受狩猎和人类迫害,无论是皮草贸易还是与牲畜的冲突。然而,缺乏评估狩猎压力对这种犬科动物种群生态影响的研究。在这项工作中,我们评估了几个与狩猎相关的变量对潘帕斯狐日常活动模式和栖息地利用的影响。在阿根廷中部的私人农场,我们进行了两次相机捕捉调查:一次在非狩猎季节,另一次在狩猎季节,区分猎人是否可以进入的地点。潘帕斯狐的栖息地利用在不同季节没有变化,但在狩猎季节,它们在人类容易看到狐狸的栖息地(即能见度高的栖息地)中的可探测性较低。潘帕斯狐狸选择黄昏和夜间,增加他们在黄昏时间在狩猎地点的活动,并显示出与栖息地能见度和季节相关的活动模式差异。狩猎压力可能与人为栖息地的改变相互作用,并在农业生态系统中为潘帕斯狐创造生态陷阱。
