Wood CO2 efflux in a primary tropical rain forest
The balance between photosynthesis and plant respiration in tropical forests may substantially affect the global carbon cycle. Woody tissue CO2 efflux is a major component of total plant respiration, but estimates of ecosystem-scale rates are uncertain because of poor sampling in the upper canopy and across landscapes. To overcome these problems, we used a portable scaffolding tower to measure ...
متن کاملComparison of ChangeDetection Techniques for Monitoring Tropical Forest Clearing and Vegetation Regrowth in a Time Series
The once remote and inaccessible forests of Guatemala's Maya Biosphere Reserve (MBR) have recently experienced high mtes of deforestation corresponding to human migration and expansion of the agricultural frontier. Given the importance of land-cover and land-use change data in conservation planning, accurate and efficient techniques to detect forest change from multi-tempoml satellite imagery w...
متن کاملStream Discharge in Tropical Headwater Catchments as a Result of Forest Clearing and Soil Degradation
Tropical Africa is affected by intense land-use change, particularly forest conversion to agricultural land. In this study, the stream discharge of four small headwater catchments located within an area of 6 km in western Kenya was examined for 2 years (2007 and 2008). The four catchments cover a degradation gradient ranging from intact forest to agricultural land under maize cultivation for 5,...
متن کاملEstimating Spatial Interactions in Forest Clearing∗
We estimate the effects of neighbors’ deforestation actions on individuals’ deforestation decisions in Costa Rica. We find evidence that neighbors’ effects are positive and significant. To address simultaneity and spatially correlated unobservable factors, we instrument for neighboring deforestation using neighboring land parcel characteristics. Under the presence of interactions, local forest ...
متن کاملBio-indicators in the tropical forest of Western Ghats environment
Background: Investigation on the natural radionuclides 238U, 232Th, 40K and natural fallout radionuclide 210Po in the prominent plants species of Western Ghats tropical forest near Kotagiri have been carried out as a part of baseline background radiation studies in the forest environment. Materials and Methods: The prominent plants species of the region Evodia roxburghiana and Eleaoca...
