Tana E. Wood & Whendee L. Silver Tropical forest soils are a major source of radiatively-active trace gases, including carbon dioxide (CO2) and nitrous oxide (N2O). Climate change is likely to alter soil moisture availability in tropical forests, and consequently the magnitude and temporal pattern of trace gas efflux from these systems (Matson & Vitousek… Continue reading Tropical Forest Rainfall Manipulation Experiment

Effects of Rangeland Management on Soil Carbon Sequestration
Rangelands represent one of the largest land-use footprints in the world and hold significant potential for employing soil carbon sequestration strategies to help mitigate climate change. California rangelands exhibit a wide range in soil carbon pool sizes. Theses differences are not correlated strongly with precipitation or soil type, indicating that management may play an important… Continue reading Effects of Rangeland Management on Soil Carbon Sequestration
Greenhouse Gas Dynamics in Bay Delta Peatlands
California’s Sacramento-San Joaquin Delta Peatlands play a significant role in the Earth’s terrestrial carbon (C) cycle, accounting for approximately one-third of the global soil C reservoir. In addition, peatland soils are a significant source of methane (CH4) to the atmosphere, a potent greenhouse gas with 25 times the global warming potential of carbon dioxide (CO2).… Continue reading Greenhouse Gas Dynamics in Bay Delta Peatlands
