Introduction Recent decades have seen a major international effort to inventory tree
communities in the Amazon Basin and Guiana Shield (Amazonia), but the vast extent and …

The distribution of plant species, the species compositions of different sites, and the factors
that affect them in tropical rain forests are not well understood. The main hypotheses are that …

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 …

The forests of Amazonia are among the most biodiverse plant communities on Earth. Given
the immediate threats posed by climate and land-use change, an improved understanding of …

The world's greatest terrestrial stores of biodiversity and carbon are found in the forests of
northern South America, where large-scale biogeographic patterns and processes have …

It is debated whether species-level differences in ecological strategy, which play a key role
in much of coexistence theory, are important in structuring highly diverse communities. We …

Amazonian rainforests are some of the most species-rich tree communities on earth. Here
we show that, over the past two decades, forests in a central Amazonian landscape have …

Amazonian forests are the largest and most diverse in the tropics, and much of the mystery
surrounding their ecology can be traced to attempts to understand them through tiny local …

Biogeographical and biodiversity studies in lowland Amazonian rain forests typically refer to
observed or postulated distribution barriers such as past unfavorable climates, mountains …

During the 1970s, tropical forest conservation focused on the preservation of old-growth
forests. In this paradigm, conservation of much of the world's terrestrial biodiversity could be …
