Most plots sampled are on acid soils in weakly seasonal rain-forest climates. reflecting the dominant conditions of the region, but span a broad environmental range includes orders example.
Amazonia appear largely insensitive to the equation used(Baker et al. 2004a, and unpublished RAINFOR analyses).
For Africa, we use the Chave et al. (2005) moist forest equation including tree height.
We then propagate the uncer- tainty in both the diameter and height parameters to obtain final biomass estimates(Lewis et al. 2009a).
We summarise findings from old-growth forests terms of(i) structural change, (ii) dynamic process change and(iii) func- tional and compositional change, over the past two to three decades, includ ing consideration of recent droughts Amazonia.
