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