| Zusammenfassung |
| Tropical ecosystems are particularly sensitive to changes in environmental conditions and
have a significant impact on the global climate due to biophysical and biogeochemical
feedbacks. It is not yet fully understood how ecosystems in the tropics will respond to a
changing climate. Thus, an improved understanding of the energy and greenhouse gas
exchange processes in tropical ecosystems is needed.
Ecosystem-scale fluxes were measured continuously by two eddy covariance flux towers
in Sardinilla, Central Panama (9.3Ë N, 79.6Ë W, 70 m a.s.l.) in a native tree plantation with a
high degree of species diversity (planted in 2001) and an adjacent, traditionally grazed
pasture. Diurnal cycles are analysed to assess differences in the driving factors of ecosystem
fluxes, seasonal differences of energy and CO2 fluxes and their interdependency with land
use. First results from nearly two years of continuous measurements will be presented and
discussed. |
