1. Temperature acts as a major factor on the timing of activity and behaviour in butterflies, and it might represent a key driver of butterfly diversification along elevation gradients. Under this hypothesis, local adaptation should be found along the elevation gradient, with butterflies from high elevation populations able to remain active at lower ambient temperature than those from low elevation.

高山蝴蝶物种复合体跨越海拔梯度的冷适应

1. 温度是影响蝴蝶活动和行为时间的主要因素，它可能是蝴蝶沿海拔梯度多样化的关键驱动因素。在这个假设下，应该沿着海拔梯度找到局部适应，来自高海拔种群的蝴蝶能够在比低海拔种群更低的环境温度下保持活跃。
