Extreme droughts in the rainforest reduce important feedback between soil and atmosphere, study finds

Isoprene is a volatile organic compound (VOC) that is produced naturally by plants.

More than 500 megatonnes of isoprene are emitted each year into Earth's atmosphere, primarily from tropical forests.

Soils are recognized sinks for atmospheric isoprene, but their behavior in natural environments remains poorly understood, particularly in the Amazon, where emissions are globally significant. ...
