Humboldt drawing 200 years ago proves effects of climate change

Two hundred years later, motivated by Humboldt's studies, a group of researchers reached this volcano located in the Ecuadorian Andes, and verified that the plant species that were at certain heights have moved more than 500 meters upwards and have reached up to areas in which they did not proliferate before, as explained in the journal "Proceedings of the National Academy of Sciences USA".

"What we have seen is that the growth limit of the plants has risen more than 500 meters, from 4,600 to 5,185 meters," explains researcher Naia Morueta-Holme in statements reproduced by the website of the Spanish newspaper El País.

“Our results show that the synergistic effects of global warming and regional land use have strong consequences on nature, and not only in temperate zones, where many studies have been done, but also in the tropics, where most of it is of biodiversity ", he adds.

“Although plants, on average, have been able to follow environmental changes, we also see many individual species that have not moved as much and are lagging behind, while others - particularly common species with good dispersal capacity and that they can sustain highly variable conditions - they have shifted even further.

We can therefore expect major changes in vegetation in the future, which raises concern about the fate of rare and specialized species, unable to keep up with environmental changes. In this context, the tropical areas are especially relevant, where most of these species live ”, concluded the Spanish-Danish researcher, according to a quote from the website of the Spanish newspaper ABC.
