Fire in the Brazilian Amazon : 3. Dynamics of biomass, C, and nutrient pools in regenerating forests
Publikováno v:
Oecologia. 124(4)
Regenerating forests have become a common land-cover type throughout the Brazilian Amazon. However, the potential for these systems to accumulate and store C and nutrients, and the fluxes resulting from them when they are cut, burned, and converted b

The Texas Public Health Training Center (TPHTC) provides quality training and education for the full spectrum of public health workers. As part of this mission, the TPHTC creates continuing education modules for nontraditional public health workers,

Tropical dry forest is the most widely distributed land-cover type in the tropics. As the rate of land-use/land-cover change from forest to pas- ture or agriculture accelerates worldwide, it is becoming increasingly important to quantify the ecosyste

Few studies have described losses of biomass and structure arising from the conversion of tropical dry forest (TDF) to pasture, a common land-use practice in the most widespread forest type in the Neotropics. We sampled total aboveground biomass (TAG

The biomass of intact tropical forests must be known in order to quantify C pools and emissions arising from biomass burning associated with deforestation, land conversion, or fragmentation. To address this need, we quantified the total aboveground b

High rates of deforestation in the Brazilian Amazon have the potential to alter the storage and cycling of carbon (C) and nitrogen (N) across this region. To investigate the impacts of deforestation, we quantified total aboveground biomass (TAGB), ab

Deforestation and land conversion in deciduous dry forests are occurring throughout the Neotropics, yet few studies have described soil N dynamics associated with this land-use/land-cover change. Soil nitrogen dynamics were measured before, and after

Burning of slashed tropical forests and pastures is among the most significant global sources of atmospheric emissions, yet the composition of the fuels and fires that creates these emissions is not well characterized. As part of the Smoke, Clouds, a
