Key message We review the recent findings on the influence of drought on tree mortality,
growth or ecosystem functioning in tropical rainforests. Drought plays a major role in …

There are a number of methods that can be used to help assess carbon budgets at the site
to continental scales. Eddy covariance (EC) networks have been developed over the last …

The measured net ecosystem exchange (NEE) of CO2 between the ecosystem and the
atmosphere reflects the balance between gross CO2 assimilation [gross primary production …

In evergreen tropical forests, the extent, magnitude, and controls on photosynthetic
seasonality are poorly resolved and inadequately represented in Earth system models …

Terrestrial ecosystems sequester 2.1 Pg of atmospheric carbon annually. A large amount of
the terrestrial sink is realized by forests. However, considerable uncertainties remain …

We investigated the seasonal patterns of Amazonian forest photosynthetic activity, and the
effects thereon of variations in climate and land-use, by integrating data from a network of …

Summary 1 Biological carbon sinks develop in mature ecosystems that have high carbon
storage when these systems are stimulated to increase productivity, so that carbon gains by …

Comparative measurements of radiation flux components and turbulent fluxes of energy and
CO 2 are made at two sites in South West Amazonia: one in a tropical forest reserve and one …

Forests around Manaus have staged the oldest and the longest forest‐atmosphere CO2
exchange studies made anywhere in the Amazon. Since July 1999 the exchange of CO2 …

With an increasing fraction of the world's forests being intensively managed for meeting
humanity's need for wood, fiber and ecosystem services, quantitative understanding of the …
