This study investigated the effects of habitat structure and climatic variables on populations of bank voles (), a northern species with adaptations to cooler climate, at the southern end of their range in Western Europe over a 16-year period. This is the first long-term analysis of its kind in this region. The study aims to understand how these variables influence the population dynamics and occupancy of bank voles. The results suggested that warmer years and extreme precipitation events lead to a reduction in bank vole abundance. Although changes in land use were minimal in the plots studied, changes in forest composition, particularly the expansion of coniferous forests at the expense of deciduous forests, were also related to lower bank vole abundance. Occupancy models, taking into account detectability, indicated stable occupancy in all regions. Our results suggest that climate change and habitat alterations, such as changes in forest composition, could pose threats to bank vole populations in these regions.
本研究调查了栖息地结构和气候变量对西欧地区棕背䶄(一种适应较凉爽气候的北方物种)种群的影响,研究时间跨度为16年,该地区位于其分布范围的南端。这是该地区首次进行此类长期分析。该研究旨在了解这些变量如何影响棕背䶄的种群动态和栖息地占用情况。结果表明,温暖年份和极端降水事件会导致棕背䶄数量减少。尽管在所研究的地块中土地利用变化极小,但森林组成的变化,特别是针叶林以阔叶林为代价的扩张,也与较低的棕背䶄数量有关。考虑到可探测性的占用模型表明,所有地区的占用情况稳定。我们的结果表明,气候变化和栖息地改变,如森林组成的变化,可能会对这些地区的棕背䶄种群构成威胁。
