The Martino’s vole (Dinaromys bogdanovi) is a rare species that lives in differently structured karst habitats, varying from open rocky plains to deep fissures, mostly residing under boulders and in crevices. Populations of the species are declining, probably due to its strict habitat preferences and competition with the European snow vole. Since the species is difficult to study in the wild, we tested its behavioral response to a differently complex environment and novel object presence in captivity. We exposed 14 individuals to differentially complex setups, from open and unsheltered to rocky with covered tunnels. We measured the effect of the presented setup and season on vole behavior. Analysis showed seasonal differences with higher movement frequency and longer time spent still during the breeding season, and a higher number of attempts due to the lack of vole entry into the experimental terrarium in the non-breeding season. Additionally, movement significantly differentiated between an open and simple setup in comparison to more complex ones, with higher frequencies of moving and peeping and the duration of peeping in the simple setup, indicating restlessness. We also found significant differences between the novel object and control setup. The results of this study could be useful for future assessment of the influence of habitat complexity on mobility in the wild. Moreover, this is the first study on the behavior of this endemic and rare rodent.

特有的马蒂诺犬田鼠Dinaromys bogdanovi（Martino 1922）对环境复杂性的行为响应

马蒂诺的田鼠（Dinaromys bogdanovi）是一种稀有物种，生活在结构不同的喀斯特生境中，从开阔的岩石平原到深裂，不等，大多居住在巨石和缝隙中。该物种的种群正在减少，这可能是由于其严格的栖息地偏好以及与欧洲雪田鼠的竞争。由于该物种很难在野外进行研究，因此我们测试了其对不同复杂环境和人工饲养新物体的行为响应。我们将14个人暴露于不同的复杂环境中，从开阔的，无遮挡的到覆盖隧道的岩石。我们测量了提出的设置和季节对田鼠行为的影响。分析表明，季节差异具有较高的移动频率，并且在繁殖季节的停留时间更长，由于在非繁殖季节没有田鼠进入实验玻璃容器，因此尝试次数增加。此外，与更复杂的设置相比，运动在开放式设置和简单设置之间有显着差异，在简单设置下，移动和窥视的频率更高，并且窥视的持续时间更长，这表明躁动不安。我们还发现了新颖对象和控件设置之间的显着差异。这项研究的结果对于将来评估栖息地复杂性对野外活动性的影响可能是有用的。此外，这是对这种地方性和稀有啮齿动物行为的首次研究。在简单的设置中，具有较高的移动和偷窥频率以及偷窥持续时间，表示烦躁不安。我们还发现了新颖对象和控件设置之间的显着差异。这项研究的结果对于将来评估栖息地复杂性对野外活动性的影响可能是有用的。此外，这是对这种地方性和稀有啮齿动物行为的首次研究。在简单的设置中，具有较高的移动和偷窥频率以及偷窥持续时间，表示烦躁不安。我们还发现了新颖对象和控件设置之间的显着差异。这项研究的结果对于将来评估栖息地复杂性对野外活动性的影响可能有用。此外，这是对这种地方性和稀有啮齿动物行为的首次研究。
