บทคัดย่อ :
The spatial and temporal dynamics of tropical forest functioning are poorly understood, partly
attributed to a weak seasonality and high tree species diversity at the landscape scale. Recent
neotropical rainforest studies with local tower flux measurements have revealed strong
seasonal carbon fluxes that follow the availability of sunlight in intact forests, while in areas
of forest disturbance, carbon fluxes more closely tracked seasonal water availability. These
studies also showed a strong seasonal correspondence of satellite measures of greenness,
using the Enhanced Vegetation Index (EVI) with ecosystem carbon fluxes in both intact and
disturbed forests, which may enable larger scale extension of tower flux measurements.
