我们利用蝙蝠探测器研究了平均气候条件和夜间天气变化对蝙蝠夏季活动的影响。夏季平均降水是与蝙蝠活动差异相关的主要气候变量，其中山地雨影区蝙蝠活动水平最高。在夜间的基础上，降雨和低温的发生与飞行活动有很强的负相关。然而，在一个地点，夜间活动的变化可以用天气来解释，相对较小。我们的研究结果表明，长期气候数据的使用为预测不同地点蝙蝠活动的变化提供了潜力。这些信息可能有助于确定太平洋西北部地形复杂、气候条件多变的蝙蝠管理的保护重点。
We examined the influence of average climatic conditions and nightly weather variations using bat detectors on the summer activity of bats. Average summer precipitation was the principal climate variable correlated with differences in bat activity along a latitudinal array of sites, with the highest activity levels occurring at sites located in montane rain shadows. On a nightly basis, the occurrence of rain and low temperatures had strong negative correlations with flight activity. However, the variation in nightly activity at a site that was explained by weather was relatively small. Our results suggest that the use of long-term climatic data offers potential to predict variations in bat activity among sites. Such information may be useful in recognizing conservation priorities for the management of bats in the Pacific Northwest where topography is complex and climate conditions are variable.
