The Saga of Leafy Spurge (Euphorbia esula) in the Northern Great Plains
Diane L. Larson
2009, Fact Sheet 2009-3066
Leafy spurge (Euphorbia esula L.) is an invasive Eurasian perennial introduced into the United States as a contaminant of crop seed in the 1880s and 1890s.

Revised multi-node well (MNW2) package for MODFLOW ground-water flow model
Leonard F. Konikow, George Z. Hornberger, Keith J. Halford, Randall T. Hanson, Arlen W. Harbaugh
2009, Techniques and Methods 6-A30
Wells that are open to multiple aquifers can provide preferential pathways to flow and solute transport that short-circuit normal fluid flowlines. Representing these features in a regional flow model can produce a more realistic and reliable simulation model. This report describes modifications to the Multi-Node Well (MNW) Package of the...
Ignoring detailed fast-changing dynamics of land use overestimates regional terrestrial carbon sequestration
S.Q. Zhao, S. Liu, Zhengpeng Li
2009, Biogeosciences (6) 1647-1654
Land use change is critical in determining the distribution, magnitude and mechanisms of terrestrial carbon budgets at the local to global scales. To date, almost all regional to global carbon cycle studies are driven by a static land use map or land use change statistics with decadal time intervals. The...
