abstract = "Background: Tropical montane cloud forests (TMCF) are unique
ecosystems with high biodiversity and large carbon reservoirs. To
date there have been limited descriptions of the carbon cycle of
TMCF. Aims: We present results on the production, allocation and
cycling of carbon for two mid-elevation (15001750 m) tropical
montane cloud forest plots in San Pedro, Kosñipata Valley, Peru.
Methods: We repeatedly recorded the components of net primary
productivity (NPP) using biometric measurements, and autotrophic
(R a) and heterotrophic (R h) respiration, using gas exchange
measurements. From these we estimated gross primary productivity
(GPP) and carbon use efficiency (CUE) at the plot level. Results:
The plot at 1500 m was found very productive, with our results
comparable with the most productive lowland Amazonian forests. The
plot at 1750 m had significantly lower productivity, possibly
because of greater cloud immersion. Both plots had similar
patterns of NPP allocation, a substantial seasonality in NPP
components and little seasonality in Ra. Conclusions: These two
plots lie within the ecotone between lower and upper montane
forests, near the level of the cloud base. Climate change is
likely to increase elevation of the cloud base, resulting in
shifts in forest functioning. Longer-term surveillance of the
carbon cycle at these sites would yield valuable insights into the
response of TMCFs to a shifting cloud base.",
