Tropical ecosystems have the highest levels of biodiversity, cycle more water and absorb
more carbon than any other terrestrial ecosystem on Earth. Consequently, these ecosystems …

Forests are the dominant terrestrial ecosystem on Earth. We review the environmental
factors controlling their structure and global distribution and evaluate their current and future …

The productivity of rainforests growing on highly weathered tropical soils is expected to be
limited by phosphorus availability. Yet, controlled fertilization experiments have been unable …

The possibility that the Amazon forest system could soon reach a tip** point, inducing
large-scale collapse, has raised global concern,–. For 65 million years, Amazonian forests …

The extent to which pre-Columbian societies altered Amazonian landscapes is hotly
debated. We performed a basin-wide analysis of pre-Columbian impacts on Amazonian …

Atmospheric carbon dioxide records indicate that the land surface has acted as a strong
global carbon sink over recent decades,, with a substantial fraction of this sink probably …

Land-use change occurs nowhere more rapidly than in the tropics, where the imbalance
between deforestation and forest regrowth has large consequences for the global carbon …

Aim Tropical forests store 25% of global carbon and harbour 96% of the world's tree species,
but it is not clear whether this high biodiversity matters for carbon storage. Few studies have …

Phosphorus availability is widely assumed to limit primary productivity in tropical forests,, but
support for this paradigm is equivocal. Although biogeochemical theory predicts that …

In 2005 and 2010 the Amazon basin experienced two strong droughts, driven by shifts in the
tropical hydrological regime possibly associated with global climate change, as predicted by …
