abstract = "Our limited understanding of the climate controls on tropical
forest seasonality is one of the biggest sources of uncertainty in
modeling climate change impacts on terrestrial ecosystems.
Combining leaf production, litterfall and climate observations
from satellite and ground data in the Amazon forest, we show that
seasonal variation in leaf production is largely triggered by
climate signals, specifically, insolation increase (70.4% of the
total area) and precipitation increase (29.6%). Increase of
insolation drives leaf growth in the absence of water limitation.
For these non-water-limited forests, the simultaneous leaf flush
occurs in a sufficient proportion of the trees to be observed from
space. While tropical cycles are generally defined in terms of dry
or wet season, we show that for a large part of Amazonia the
increase in insolation triggers the visible progress of leaf
growth, just like during spring in temperate forests. The
dependence of leaf growth initiation on climate seasonality may
result in a higher sensitivity of these ecosystems to changes in
climate than previously thought.This is an open access article
