一段时间以来，人们已经知道小气候会驱动昆虫分布和丰度的变化。然而，直到最近，小气候效应的量化一直受到计算限制和精细尺度生物数据的可用性的限制。在这里，我们测试了蝴蝶和飞蛾的持久性/灭绝的细尺度模式对来自数字高程模型的小气候的两个计算指数：夏季太阳能指数，代表细尺度的温度变化，和地形湿度指数，代表细尺度的水分可用性的变化。我们在四个20 × 20 km的英国景观中（Brecks，Broads，Dartmoor和Exmoor）发现了小气候对持久性影响的证据。一般来说，当地的反射更频繁地发生在较高的最小或最大太阳辐射输入的地区，而对湿度的反应因景观而异。这种对太阳辐射的负响应与对气候变暖的响应一致，其中具有特别高的最小或最大日照值的网格正方形随着气候变暖而提供越来越不利的小气候。不同景观对湿度的可变响应可能反映了降水的空间变化趋势。我们建议，在景观中具有较低的最低和/或最高温度的位置可以作为气候变暖的避难所，因此可能有一个有价值的作用，在适应气候变化的保护。
Microclimate has been known to drive variation in the distribution and abundance of insects for some time. Until recently however, quantification of microclimatic effects has been limited by computing constraints and the availability of fine-scale biological data. Here, we tested fine-scale patterns of persistence/extinction in butterflies and moths against two computed indices of microclimate derived from Digital Elevation Models: a summer solar index, representing fine-scale variation in temperature, and a topographic wetness index, representing fine-scale variation in moisture availability. We found evidence of microclimate effects on persistence in each of four 20 × 20 km British landscapes selected for study (the Brecks, the Broads, Dartmoor, and Exmoor). Broadly, local extinctions occurred more frequently in areas with higher minimum or maximum solar radiation input, while responses to wetness varied with landscape context. This negative response to solar radiation is consistent with a response to climatic warming, wherein grid squares with particularly high minimum or maximum insolation values provided an increasingly adverse microclimate as the climate warmed. The variable response to wetness in different landscapes may have reflected spatially variable trends in precipitation. We suggest that locations in the landscape featuring cooler minimum and/or maximum temperatures could act as refugia from climatic warming, and may therefore have a valuable role in adapting conservation to climatic change.
