Climate Drivers of Carbon Gain and Water Loss in a Southern Appalachian Forest

The planet is warming, and warmth revs the machinery of life. “As it gets warmer, living things burn up more carbon through respiration,” says USDA Forest Service scientist Chris Oishi. “It’s true of trees and soil microbes.” Soil is bursting with invertebrate life, microbial life, and living plant roots. It’s also where decomposers do their…  More 

More Benefits of Cool Mountain Air

In mountainous areas, cold air flows along the surface of the earth from mountain tops to valleys, and as it moves, it dramatically affects local temperatures. “Many ecosystem processes – including carbon uptake and storage – are affected by temperature,” says U.S. Forest Service research ecologist Chris Oishi. Oishi recently contributed to a study on how…  More 

Effects of Elevated Carbon Dioxide on Sweetgum Bark

Carbon is the chemical foundation of all living things. Animals consume carbon indirectly – either by eating other animals or by eating plants. However, plants absorb carbon (in the form of carbon dioxide, or CO2), directly from the air. “The global atmospheric concentration of CO2 has been reported to have risen by 35 percent over…  More
