Cold-adapted taxa are experiencing severe range shifts due to climate change and are expected to suffer a significant reduction of their climatically suitable habitats in the next few decades. However
The study of ecological niche evolution is fundamental for understanding how the environment influences species’ geographical distributions and their adaptation to divergent environments. Here we pres
The Arctic is warming four times faster than the rest of the world, threatening the persistence of many Arctic species. It is uncertain if Arctic wildlife will have sufficient time to adapt to such ra
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 mainlan
The geographic ranges of closely related species can vary dramatically, yet we do not fully grasp the mechanisms underlying such variation. The niche breadth hypothesis posits that species that have e
