What to know about Scientific Research

A study published in Global Change Biology indicates that a small group of 15–25 tree species are primarily responsible for the regeneration of the Amazon rainforest and carbon storage in razed areas. Lead researcher Fernando Elias explains that these pioneer species create the necessary conditions for more sensitive, primary forest species to return.
