Hyperdominance in the Amazonian Tree Flora
The finding that Amazonia is dominated by just 227 tree species implies that most biogeochemical cycling in the world’s largest tropical forest is performed by a tiny sliver of its diversity.
Long-term decline of the Amazon carbon sink
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 located in the…
Height-diameter allometry of tropical forest trees
Abstract. Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in…
Tree height integrated into pantropical forest biomass estimates
Abstract. Aboveground tropical tree biomass and carbon storage estimates commonly ignore tree height (H). We estimate the effect of incorporating H on tropics-wide forest biomass estimates in 327…

It is found that dominance of forest function is even more concentrated in a few species than is dominance of tree abundance, with only ≈1% of Amazon tree species responsible for 50% of carbon storage and productivity.

Pantropical biomass maps are widely used by governments and by projects aiming to reduce deforestation using carbon offsets, but may have significant regional biases and carbon accounting techniques must be revised to account for the known ecological variation in tree wood density and allometry.
Persistent effects of pre-Columbian plant domestication on Amazonian forest composition
Analysis of plant distributions, archaeological sites, and environmental data indicates that modern tree communities in Amazonia are structured to an important extent by a long history of plant domestication by Amazonian peoples.

A unique pan-tropical dataset of 360 plots located in structurally intact old-growth closed-canopy forest is compiled, surveyed using standardised methods, allowing a multi-scale evaluation of diversity-carbon relationships in tropical forests.
OBSERVATIONS ON THE VEGETATION OF NORTHEASTERN MATO GROSSO, BRAZIL. IV. AN ANALYSIS OF THE CERRADO–AMAZONIAN FOREST ECOTONE
A study was made of the transition between the cerrado and Amazonian forest biomes on the Serra do Roncador in the northeast of Mato Grosso State, Brazil. The transition was sampled by recording the…
