Climate change is modifying plant communities and ecosystems around the world. Alpine ecosystems are of special concern on oceanic islands, due to their characteristic higher endemicity rate, small area and undergoing severe climate change impact in the last few decades. During recent decades there has been increasing interest in the effects of cli...

We analyse the oldest available data on the high‐elevation vegetation on Tenerife's Mt. Teide, namely the species shown in A. von Humboldt's (1817) Tableau Physique des Iles Canaries (TPIC), which is based on his own 1799 visit and an 1815 visit by L. von Buch and C. Smith. The analysis is of interest in the context of climate change and biotic cha...

Global warming is changing the structure and elevational limits of treelines around the world. This could become a threat particularly on islands, where usually high mountain ecosystems occupy small areas. Tenerife, with a maximum elevation of 3715 m, is an excellent example of this. In this subtropical island, the treeline composed by endemic pine...
