This is the page for our belowground carbon work in the EEON. Check back for updates, and see our belowground ecology blog from the field and ecosystem ecology lab at: http://blogs.evergreen.edu/ecology/belowground-ecology/
Here is a figure from our recent work showing a positive relationship between tree diversity and soil CO2 efflux.
Our lab uses multiple methods to understand variation in below ground processes in response to tree diversity. We have examined C flux below ground using scanner-based minirhizotron technology (CI-600), IRGA technology, estimation of total below ground carbon allocation, root excavation, and (in collaboration with other labs) nitrogen mineralization and microbial community techniques.
The CI-600 is a scanner based technology which takes large underground images (21.59 x 19.56 cm) in buried 6.99 cm diam. acrylic tubes. For more information please see www.cid-inc.com.
