Light is a key resource for plant growth and is of particular importance in forest ecosystems, because of the strong vertical structure leading to successive light interception from canopy to forest floor. Tree species differ in the quantity and heterogeneity of light they transmit. We expect decreases in both the quantity and spatial heterogeneity of light transmittance in mixed stands relativ...
Biomass accumulation of dierent grass species can be quanti®ed by leaf area index (LAI) development, the Beer±Lambert light interception function, and a species-speci®c radiation-use eciency (RUE). The object of this ®eld study was to compare RUE values and leaf CO2 exchange rates (CER) for four C4 grasses. Biomass, LAI, and fraction of photosynthetically active radiation (PAR) intercepted we...
Tropical rainforest clearing and degradation significantly reduces carbon sequestration and increases the rate of biodiversity loss. There has been a concerted international effort to develop remote sensing techniques to monitor broad-scale patterns of forest canopy disturbance. In addition to loss of natural resources, recent deforestation in Mesoamerica threatens historic cultural resources t...
