Age‐dependent leaf physiology and consequences for crown‐scale carbon uptake during the dry season in an Amazon evergreen forest

What is it about?

Central Amazon evergreen forests show an odd increase in capacity for photosynthesis during the dry season. Some past studies showed that new leaf production caused this increase, but until now no study had directly examined physiology of leaves with different ages, and counted the number of leaves of different ages on branches in the same trees in a central Amazon evergreen forest. We did this and found that new leaf production can indeed explain the dry season photosynthesis pattern.
