Seasonal Changes in Amazon Photosynthesis Explained

Previously, researchers looking to project how tropical forests will respond to future climate change have been fraught with overly simplistic assumptions about levels of photosynthesis within the tree canopies. But even though the forests always look green, even from space, researchled by scientists from the University of Arizona and the National Institute for Amazon Research in Brazil has discovered the reason for a discrepancy between large seasonal changes in photosynthesis in the Amazon forest. The synchronization of new-leaf growth with old-leaf loss causes large seasonal increases in “greenness,” which should help scientists predict how the forests respond to climate change.
