Quantifying water flow and retention in an unsaturated fracture-facial domain
John R. Nimmo, Siamak Malek-Mohammadi
2015, Book chapter, Fluid dynamics in complex fractured-porous systems
Hydrologically significant flow and storage of water occur in macropores and fractures that are only partially filled. To accommodate such processes in flow models, we propose a three-domain framework. Two of the domains correspond to water flow and water storage in a fracture-facial region, in addition to the third domain...

Linear models for airborne-laser-scanning-based operational forest inventory with small field sample size and highly correlated LiDAR data
Virpi Junttila, Tuomo Kauranne, Andrew O. Finley, John B. Bradford
2015, IEEE Transactions on Geoscience and Remote Sensing (53) 5600-5612
Modern operational forest inventory often uses remotely sensed data that cover the whole inventory area to produce spatially explicit estimates of forest properties through statistical models. The data obtained by airborne light detection and ranging (LiDAR) correlate well with many forest inventory variables, such as the tree height, the timber...

David W. Clow, Sarah M. Stackpoole, Kristine L. Verdin, David E. Butman, Zhi-Liang Zhu, David P. Krabbenhoft, Robert G. Striegl
2015, Environmental Science & Technology (49) 7614-7622
Organic carbon (OC) burial in lacustrine sediments represents an important sink in the global carbon cycle; however, large-scale OC burial rates are poorly constrained, primarily because of the sparseness of available data sets. Here we present an analysis of OC burial rates in water bodies of the conterminous U.S. (CONUS)...

Jonathan C. B. Nesmith, Adrian J. Das, Kevin L. O’Hara, Phillip J. van Mantgem
2015, Canadian Journal of Forest Research (45) 910-919
Tree mortality is a vital component of forest management in the context of prescribed fires; however, few studies have examined the effect of prefire tree health on postfire mortality. This is especially relevant for sugar pine (Pinus lambertiana Douglas), a species experiencing population declines due to a suite of anthropogenic factors....

2015, Landscape Ecology (30) 1095-1110
Context Threats to wildlife species from extreme events, such as droughts, are predicted to increase in frequency and magnitude with climate change. Extreme events can cause mortality and community-level changes, but for some mobile species, movement away from areas affected may be a viable option. Objectives <p id="Par2" class="Para...

Phosphorus loading declined between the 1970s and the 1990s, leading to oligotrophication of the offshore waters of Lake Ontario during that time period. Using lake-wide data from the intensive field years of 2003 and 2008 and from available long-term data sets on several trophic state indicators (total phosphorus [TP], soluble...

2015, Journal of Great Lakes Research (41) 266-279
We examined how attack frequency by sea lampreys on fishes in Lake Ontario varied in response to sea lamprey abundance and preferred host abundance (lake trout > 433 mm). For this analysis we used two gill net assessment surveys, one angler creel survey, three salmonid spawning run datasets, one adult sea lamprey assessment, and...

Surface monitoring of microseismicity at the Decatur, Illinois, CO2 sequestration demonstration site
J. Ole Kaven, Stephen H. Hickman, Arthur F. McGarr, William L. Ellsworth
2015, Seismological Research Letters (86) 1096-1101
Sequestration of CO2 into subsurface reservoirs can play an important role in limiting future emission of CO2 into the atmosphere (e.g., Benson and Cole, 2008). For geologic sequestration to become a viable option to reduce greenhouse gas emissions, large-volume injection of supercritical CO2 into deep sedimentary formations is required. These...

Control of nitrogen and phosphorus transport by reservoirs in agricultural landscapes
Stephen M. Powers, Jennifer L. Tank, Dale M. Robertson
2015, Biogeochemistry (124) 417-439
Reservoirs often receive excess nitrogen (N) and phosphorus (P) lost from agricultural land, and may subsequently influence N and P delivery to inland and coastal waters through internal processes such as nutrient burial, denitrification, and nutrient turnover. Currently there is a need to better understand how reservoirs affect nutrient transport...

John R. Matchett, Philip B. Stark, Steven M. Ostoja, Roland A. Knapp, Heather C. McKenny, Matthew L. Brooks, William T. Langford, Lucas N. Joppa, Eric L. Berlow
2015, Scientific Reports (5)
Statistical models often use observational data to predict phenomena; however, interpreting model terms to understand their influence can be problematic. This issue poses a challenge in species conservation where setting priorities requires estimating influences of potential stressors using observational data. We present a novel approach for inferring influence of a...
