哺乳动物捕食者的种间相互作用的例子已被描述，但较少被称为国内捕食者的本地捕食者公会的干扰。我们调查了三种机会性捕食者（狗（Canis lupus familiaris L.，1758）、猫（Felis卡图斯L.，1758））和赤狐（Vulpesvulpes（L.，1758））共同发生在波兰中部的广阔农田。他们的空间使用监测跟踪站分布在外地和森林地块沿着距离梯度的建筑物和分析使用占用建模框架。对于所有这三个物种的占用率随着距离建筑物的增加而下降，虽然狐狸的模式相对较弱。猫在车站的发生率较高，在森林中比在外地，狐狸和狗，有一个很大的变化之间的研究地块。对于所有三种捕食者，检测的概率在夜间高于白天，并在季节之间变化;然而，确切的模式是物种特异性的。一个捕食者的存在也与其他两个物种的存在有关，一般来说，在其他两个物种不存在的情况下，一个特定的物种被检测到的频率更高。我们记录的时空生态位分离之间的三个物种。我们的结论是种间的拮抗作用和觅食生态的差异是形成农业景观中的三种共现的主要驱动力。
Examples of interspecific interactions have been described for mammalian predators, but less is known regarding disturbances of native predator guilds by domestic predators. We investigated intraguild interactions among three opportunistic predators (dog (Canis lupus familiaris L., 1758), cat (Felis catus L., 1758)), and red fox (Vulpes vulpes (L., 1758)) co-occurring in the extensive farmlands of central Poland. Their space use was monitored using tracking stations distributed in field and forest plots along a distance gradient from buildings and analyzed using the occupancy-modeling framework. For all three species occupancy decreased with increased distance from buildings, although for the fox the pattern was relatively weak. The occurrence of cats at the stations was higher in the forest than in the field; for fox and dog, there was a strong variation between study plots. For all three predators, the probability of detection was higher during the night than during the day and varied between the seasons; however, the exact patterns were species-specific. The presence of one predator was also linked to the presence of the other two species generally, a given species was detected more frequently in the absence of the other two species. We recorded spatiotemporal niche segregation among the three species. We conclude that interspecific antagonistic interactions and differences in foraging ecology are the main drivers shaping co-occurrence of the three species in the agriculture landscape.
