The 50 plots that have two consecutive census intervals can be separated into two groups, one fast-growing and more dynamic(mostly in western Amazonia), and one slow-growing and much less dynamic(mostly in eastern and central Amazonia), which reflects the dominant macroecological gradient across Amazonia(Phillips et al. 2004; Quesada et al. 2012 ter Steege et al. 2006). Both groups showed increased stem recruitment, stem mortality, stand basal area growth and stand basal area mortality, with greater absolute increases in rates in the faster-growing and more dynamic sites than in the slower-growing and less dynamic sites(Figure 4.6; Lewis et al. 2004b), but similar and statisti- cally indistinguishable proportional increases in rates among forest types(Lewis et al. 2004b). It should be stressed that these results represent the mean response of all mature forests measured. Within our dataset, there are many individual plots showing different, individual responses, just as within the whole literature there are some reports of individual sites showing
