尽管小气候管理的有效性很少得到研究，但通过生境管理创造小气候变化通常被提倡为缓解气候变暖影响的一种方式。我们比较了1997年至2010年英国怀特岛南海岸一个地点的生境质量（适宜的温暖小气候的可用性）和环境气温对高度喜热蝴蝶Glanville贝母（melitaea cinxia）丰度的时间变化。对不同生境演替阶段下的地温进行了测量和比较，并探讨了蝴蝶丰度与寄主植物和天气变量的关系。栖息地质量的时间变化几乎是环境空气温度对蝴蝶数量预测的两倍。我们没有发现丰度和降雨量之间的关系。生境下的地温比较表明，演替早期比演替后期明显温暖，样地内Glanville贝母幼虫“网”的分布仅限于这些较温暖的生境。怀孕雌虫选择的产卵寄主也比环境温度高得多。栖息地质量的重要性强化了这样一种观念，即喜热昆虫将受益于创造热多样性环境的现场管理实践。异质生境为不适应气候变化的物种提供了避难所，也为它们扩大活动范围提供了机会。
Creating variation in microclimates through habitat management is often advocated as a way of ameliorating the impact of climate warming, although the effectiveness of microclimate management has rarely been studied. We compared temporal variation in habitat quality (the availability of suitably warm microclimates) and ambient air temperature on the abundance of a highly thermophilous species of butterfly, the Glanville fritillaryMelitaea cinxia, at one site on the south coast of the Isle of Wight, UK, from 1997 to 2010. Ground temperatures beneath the various habitat successional stages were measured and compared, and the relationship between butterfly abundance and hostplant and weather variables was examined. Temporal variation in habitat quality was almost twice as strong as a predictor of butterfly abundance as ambient air temperature. We found no relationship between abundance and rainfall. Comparisons of ground temperatures beneath habitats showed that earlier successional stages were considerably warmer than later successional stages, and the distribution of Glanville fritillary larval ‘webs’ within plots was restricted to these warmer habitats. Hostplants selected for oviposition by gravid females were also considerably warmer than ambient temperature. The importance of habitat quality reinforces the notion that thermophilous insects would benefit from site management practices that create thermally diverse environments. Heterogeneous habitats provide refugia for species intolerant of climate change, as well as opportunities for range expansion.
