摘要
Many animal life-history stages center around residences (nests, roosts, etc.) where the availability of resources within an optimal range can affect fitness. Understanding factors influencing residence selection is fundamental for efficient management or recovery plans. Many bat species use permanent roosts during different periods of the year, and while most conservation plans aim to protect these roosts, the availability of suitable habitat near the roosts (e.g., foraging habitat) is also critical to consider. We evaluated the importance of landscape features at multiple scales surrounding seasonal bat roosts in two regions (north and south) of Québec (Canada), using data from participatory science and government databases. In the human-altered environment of south Québec, bats selected maternity roosts with high anthropogenic cover and water edge density at the 150 m and 2 km scales, respectively. Conversely, roost selection in north Québec, a forested area, could not be explained by any landscape features. In winter, fewer bats used hibernacula located in heavily human-modified landscapes—opposite to the trend observed with maternity roost selection. Our study demonstrates how considering landscape features at the appropriate temporal and spatial scales can promote more efficient conservation for bats.

许多动物生活史阶段围绕住宅（巢，栖息地等），其中最佳范围内资源的可用性可能会影响健身。了解影响居住选择的因素对于有效的管理或恢复计划是基础。许多BAT物种在一年中的不同时期使用永久栖息地，尽管大多数保护计划旨在保护这些栖息地，但在栖息地附近的合适栖息地（例如，觅食栖息地）也至关重要。我们使用参与式科学和政府数据库的数据评估了在魁北克省两个地区（北部和南部）季节性蝙蝠栖息的多个尺度上的景观特征的重要性。在魁北克省南部的人类变化环境中，蝙蝠在150 m和2 km尺度上选择了具有高人为覆盖物和水边缘密度的产妇栖息地。相反，在森林地区北魁北克的Roost选择无法用任何景观特征来解释。在冬季，更少的蝙蝠使用位于重度人体改造的景观中的Hibernacula，这是孕妇栖息地选择所观察到的趋势。我们的研究表明，在适当的时间和空间尺度上考虑景观特征如何促进蝙蝠的更有效的保护。
