The Amazon rainforest has been found to emit new stress-defense molecules during periods of drought, such as the severe El Niño drought. This response is a defense mechanism used by the vegetation to cope with environmental stress. The discovery was made by researchers at the Max Planck Institute for Chemistry, who studied the effects of the 2023-2024 El Niño cycle on the rainforest. The findings were published in a scientific journal, detailing the changes in chemical emissions by the vegetation during this time. This development shows the rainforest's ability to adapt to extreme conditions, highlighting its resilience in the face of environmental stress.
