abstract = "Background: The forests of western Amazonia are known to be more
dynamic that the better-studied forests of eastern Amazonia, but
there has been no comprehensive description of the carbon cycle of
a western Amazonian forest. Aims: We present the carbon budget of
two forest plots in Tambopata in south-eastern Peru, western
Amazonia. In particular, we present, for the first time, the
seasonal variation in the detailed carbon budget of a tropical
forest. Methods: We measured the major components of net primary
production (NPP) and total autotrophic respiration over 36 years.
Results: The NPP for the two plots was 15.1 ± 0.8 and 14.2 ± 1.0
Mg C ha\−1 year\−1, the gross primary productivity
(GPP) was 35.5 ± 3.6 and 34.5 ± 3.5 Mg C ha\−1
year\−1, and the carbon use efficiency (CUE) was 0.42 ±
0.05 and 0.41 ± 0.05. NPP and CUE showed a large degree of
seasonality. Conclusions: The two plots were similar in carbon
cycling characteristics despite the different soils, the most
notable difference being high allocation of NPP to canopy and low
allocation to fine roots in the Holocene floodplain plot. The
timing of the minima in the wetdry transition suggests they are
driven by phenological rhythms rather than being driven directly
by water stress. When compared with results from forests on
infertile forests in humid lowland eastern Amazonia, the plots
have slightly higher GPP, but similar patterns of CUE and carbon
allocation.",
