Belowground Ecology:
Our lab uses multiple methods to understand variation in belowground processes in response to tree diversity. We have examined C flux belowground using IRGA technology, estimation of total belowground carbon allocation, root excavation, minirhizotron technology, and (in collaboration with other labs) nitrogen mineralization and microbial community techniques. Our work has focused on three systems: 1) the
intermountain west cottonwood hybrid system between native Populus
trees P. angustifolia and P. fremontii (since 2001).
More about the Cottonwood System.
2) second-growth temperate rainforests on the Evergreen College reserve (minirhizotron and IRGA work since 2006). More about the EEON network 3) East Cascades ponderosa pine systems (Sinlahekin valley, WA - since 2008). |

The CI-600 mini-rhizotron we use is a scanner based technology which takes large images (21.59 x 19.56 cm) in 6.99 cm diam. acrylic tubes. For more information please see www.cid-inc.com.
