了解气候变暖如何影响物种间的相互作用对于理解当前的生物多样性变化至关重要。我们回顾了瑞典蝴蝶在最近几十年的物候变化，并探讨潜在的气候影响蝴蝶寄主植物相互作用的橙子尖蝴蝶Anthocharis豆蔻和它的寄主植物作为一个模式系统。该蝶的出现日期大大提前，其平均飞行日期与纬度呈正相关。我们发现，有一个大的纬度变化，在主机使用和蝴蝶种群选择植物个体的开花物候的基础上。我们的结论是A.小豆蔻是物候学专家，但却是寄主物种的通才。这意味着春季发育的热可塑性通过影响其与寄主植物的物候匹配来影响蝴蝶的寄主利用。然而，A.小豆蔻似乎使其对相对较大的气候变化具有弹性。本文的在线版本（doi：10.1007/s13280-014-0602-z）包含补充材料，可供授权用户使用。
Knowledge of how species interactions are influenced by climate warming is paramount to understand current biodiversity changes. We review phenological changes of Swedish butterflies during the latest decades and explore potential climate effects on butterfly–host plant interactions using the Orange tip butterfly Anthocharis cardamines and its host plants as a model system. This butterfly has advanced its appearance dates substantially, and its mean flight date shows a positive correlation with latitude. We show that there is a large latitudinal variation in host use and that butterfly populations select plant individuals based on their flowering phenology. We conclude that A. cardamines is a phenological specialist but a host species generalist. This implies that thermal plasticity for spring development influences host utilization of the butterfly through effects on the phenological matching with its host plants. However, the host utilization strategy of A. cardamines appears to render it resilient to relatively large variation in climate.
