Cold adaptation

Since Darwin, researchers have explored how species adapt to different elevations. Tropical reptiles, typically diverse in warm lowlands, have also colonized high elevations on islands and the mainland. The frequency of such transitions has been unclear.自达尔文时代以来，研究者们便一直在探索物种如何适应不同海拔环境。通常在温暖低地物种多样性颇为丰富的热带爬行动物，也已在岛屿与大陆的高海拔区域完成了拓殖定植。这类海拔分布跃迁事件的发生频率此前仍不明确。
