Tropical forests ‘fix’ themselves

Tropical forests speed their own recovery, capturing nitrogen and carbon faster after being logged or cleared for agriculture. Researchers working at the Smithsonian Tropical Research Institute in Panama think the discovery that trees «turn up» their ability to capture or «fix» nitrogen from the air and release it into the soil as the forest makes a comeback has far-reaching implications for forest restoration projects to mitigate global warming.
