Biodiversity in the Amazon is Threatened by Deforestation

By Samantha Mathewson

After surveying 2,000 species of plants, birds, beetles, ants and bees across more than 300 diverse sites in the Brazilian Amazon, researchers say that deforestation has, without a doubt, caused a strong loss of biodiversity. They also say that setting aside a network of preserved forest may make it possible to maintain different populations of plants and animals. Their findings were recently published in the journal Ecology Letters.

“Pre-existing differences in the undisturbed forests plus the way in which they had been altered by human activity had an impact on which species survived.” Dr. Ricardo Solar, lead author of the study and a research fellow at Brazil´s Universidade Federal de Viçosa, said a statement. “Some of the disturbed forests were able to maintain up to 80 percent of the species found in pristine forests — this gives us hope. It is vitally important that reserves should not be concentrated in a single part of a region, but as a widespread network of forest reserves.”
