Multi-scale comparisons of tree composition in Amazonian terra firme forests [PDF]

Biogeosciences, 2009
We explored the floristic composition of terra firme forests across Amazonia using 55 plots. Firstly, we examined the floristic patterns using both genus- and species-level data and found that the species-level analysis more clearly distinguishes among ...
