Activity patterns and habitat use are important for understanding the natural history of a species and its ecology. Some species of carnivore are abundant, but little studied, such as the tayra (Eira barbara). In this context, the activity patterns and environmental factors that influence tayra frequency of occurrence in high montane tropical rainforests in the Atlantic Rainforest biome were evaluated. A total of 32 points distributed in the Itatiaia National Park and the Alto Montana Natural Heritage Reserve were investigated for three years, in a gradient ranging from 800 to 2200 m elevation. Tayra frequency of occurrence was evaluated using camera traps and environmental variables were obtained. Photo time data indicate that tayra are predominantly diurnal and their frequency of occurrence is higher at lower elevations and in areas more distant from human habitation. Although this species occurs at all elevation, the tayra may prefer lower elevation habitats, due to the higher productivity of these areas compared to higher elevational environments. The results reported herein contribute to a better knowledge of the species and may aid in planning models and conservation actions for ecological function and tropical biodiversity maintenance.

活动模式和栖息地的使用对于理解物种的自然历史及其生态学非常重要。某些食肉动物种类丰富，但很少研究，例如tayra（Eira barbara）。在这种情况下，评估了影响大西洋雨林生物群落中高山区热带雨林中泰勒发生频率的活动模式和环境因素。连续三年调查了分布在Itatiaia国家公园和Alto Montana自然遗产保护区的32个点，海拔范围为800至2200 m。使用照相机诱捕器评估Tayra的发生频率，并获得环境变量。拍摄时间的数据表明，泰勒族主要是昼夜节律，它们的发生频率在较低海拔和距人类居住区较远的地区较高。尽管该物种出现在所有海拔高度，但由于与高海拔环境相比，这些地区的生产力更高，因此泰勒可能更喜欢低海拔栖息地。
