[font size=4]UD researchers discover tree trunks act as methane source in upland forests[/font]
[font size=3]A new study from the University of Delaware is one of the first in the world to show that tree trunks in upland forests actually emit methane rather than store it, representing a new, previously unaccounted source of this powerful greenhouse gas.
Methane is about 25 times stronger than carbon dioxide, with some estimates as high as 33 times stronger due to its effects when it is in the atmosphere.
Because of methanes global warming potential, identifying the sources and sinks or storehouses of this greenhouse gas is critical for measuring and understanding its implications across ecosystems.
Upland forest soils usually take up and store methane, but this effect can be counteracted by methane emissions from tree trunks, the research team from UDs College of Agriculture and Natural Resources found. Their work is published in the scientific journal
Ecosystems.
