Methane Emissions and Tree Research

Nick Ward and Matt Norwood, biogeochemists, explore greenhouse gas cycling, focusing on methane, a potent greenhouse gas with significant warming potential. They study methane emissions from trees, a recently discovered phenomenon, using portable instruments and tree core analysis. Their research includes identifying microbial activity in wood that produces methane, using tools like resistance drills and genomic analysis in labs.

• A thermometer

What is the purpose of using tree cores in the study?

• To study annual growth rates and methane production

• To measure tree height

• To count the number of branches

• To analyze leaf color

What does a dark orange section in a tree core indicate?

• Microbial-induced methane production

• Healthy wood

• Water damage

• Insect infestation

What is a resisted graph used for?

• Analyzing soil composition

• Measuring tree height

What is the role of methanogens in the study?

• They have no role

• They absorb CO2

• They produce methane

• They convert methane to water

What is the significance of finding microbes in wood?

• It means the tree is dying

• It indicates healthy tree growth

• It suggests methane production
