Recently confirmed expansion of golden jackals (Canis aureus) into countries without any previous records poses questions, one of them focusing on the species potential and possibly varying habitat use. In this study, we investigated the presence and distribution of golden jackals in northern Bosnia and Herzegovina, where knowledge about golden jackal distribution and habitat use is still scarce. We used bioacoustic stimulation as a non-invasive tool to gather data on golden jackal presence. Habitat structures potentially selected by the species were assessed at 92 calling stations and used as input for binary logistic regression models. Our study area covered approximately 1150 km2, and bioacoustic stimulation within this area resulted in an estimated minimum relative group density of 3.5 territorial groups per 100 km2. We found territorial groups at distances between 15 and 38 km southwards from the river Sava but always within a maximum range of 3 km to perennial watercourses. Habitat analysis identified shrub vegetation and pastures as structures with a significant effect on the presence of resident golden jackals. Probability that golden jackals answered at calling stations increased with increasing surface area covered with pastures and shrubs. Distances between golden jackal territories and the nearest human settlement were relatively small. Our results indicate that structures like transitional woodland-shrubs and pastures, together with other potential influencing factors like local agricultural practices, low hunting pressure, diverse natural and anthropogenic food sources, could have benefited the settlement of golden jackals in the northern lowlands of Bosnia and Herzegovina.

在波斯尼亚和黑塞哥维那北部的河沿地区栖息地栖息金jack(犬金黄色)

最近确认的金狐(Canis aureus)在没有任何先前记录的国家中的扩张引起了疑问,其中之一集中在物种潜力和可能的栖息地用途上。在这项研究中,我们调查了波斯尼亚和黑塞哥维那北部金狐狼的存在和分布,那里对金狐狼分布和栖息地使用的知识仍然匮乏。我们使用生物声学刺激作为非侵入性工具来收集有关金黄狐狼存在的数据。该物种可能选择的栖息地结构在92个呼叫站进行了评估,并用作二元逻辑回归模型的输入。我们的学习区域约1150 km 2,并且该区域内的生物声刺激导致每100 km 2估计最小相对群密度为3.5个地域。我们在距萨瓦河以南15至38公里的范围内发现了领土群,但一直到常年水道的最大距离始终在3公里之内。生境分析确定灌木植被和草场为对居住的金色jack狼的存在具有重大影响的结构。金黄jack狼在呼叫站接听的概率随牧场和灌木覆盖的表面积的增加而增加。黄金jack狼领地与最近的人类住区之间的距离相对较小。我们的结果表明,过渡林地灌木和牧场等结构,以及其他潜在影响因素,例如当地的农业实践,低狩猎压力,多种自然和人为食物来源,
