城市化和气候变化是影响动物分布的两个全球变化过程，对生物多样性构成严重威胁。由于其多功能的生态和synurbic的习惯，库尔的伏翼（伏翼kuhlii）提供了一个独特的机会，探索气候变化和城市化对物种分布的相对影响。在气候变化的情况下，这种典型的地中海物种预计将扩大其范围，以应对不断上升的温度。我们收集了1980年至2013年期间来自P. kuhlii欧洲范围的25，132个高分辨率发生记录，并使用三个生物气候变量和一个城市化代理，采用多时相方法模拟了该物种的分布。温度在一年中最冷的季度是最重要的因素预测存在的P. kuhlii，并在研究期间表现出增加的趋势;年平均降水量和降水季节性也相关，但程度较低。虽然城市化在最近殖民的地区有所增加，但它对物种存在的可预测性几乎没有影响。在过去的四十年里，P. kuhlii的地理范围扩大了约394%，这一过程可以解释为对气候变化的反应。
Urbanisation and climate change are two global change processes that affect animal distributions, posing critical threats to biodiversity. Due to its versatile ecology and synurbic habits, Kuhl's pipistrelle (Pipistrellus kuhlii) offers a unique opportunity to explore the relative effects of climate change and urbanisation on species distributions. In a climate change scenario, this typically Mediterranean species is expected to expand its range in response to increasing temperatures. We collected 25,132 high-resolution occurrence records from P. kuhlii European range between 1980 and 2013 and modelled the species' distribution with a multi-temporal approach, using three bioclimatic variables and one proxy of urbanisation. Temperature in the coldest quarter of the year was the most important factor predicting the presence of P. kuhlii and showed an increasing trend in the study period; mean annual precipitation and precipitation seasonality were also relevant, but to a lower extent. Although urbanisation increased in recently colonised areas, it had little effect on the species' presence predictability. P. kuhlii expanded its geographical range by about 394 % in the last four decades, a process that can be interpreted as a response to climate change.
