EEON

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.

Root Scanner:

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.
