Potential impacts of climate change on soil erosion vulnerability across the conterminous United States

Creator:: Segura, C., Sun, G., McNulty, S., and Zhang, Y.
Abstract:: Rainfall runoff erosivity (R) is one key climate factor that controls water erosion. Quantifying the effects of climate change–induced erosivity change is important for identifying critical regions prone to soil erosion under a changing environment. In this study we first evaluate the changes of R from 1970 to 2090 across...

Impact of land use patterns and agricultural practices on water quality in the Calapooia River Basin of western Oregon

Creator:: Mueller-Warrant, G. W., Griffith, S. M., Whittaker, G. W., Banowetz, G. M., Pfender, W. F., Garcia, T. S., and Giannico, G. R.
Abstract:: Agricultural practices, including tillage, fertilization, and residue management, can affect surface runoff, soil erosion, and nutrient cycling. These processes, in turn, may adversely affect (1) quality of aquatic resources as habitat for amphibians, fish, and invertebrates, (2) costs of treating surface and ground water to meet drinking water standards, and...

State of the Art in Large-Scale Soil Moisture Monitoring

Creator:: Ochsner, Tyson E., Cosh, Michael H., Cuenca, Richard H., Dorigo, Wouter A., Draper, Clara S., Hagimoto, Yutaka, Kerr, Yann H., Larson, Kristine M., Njoku, Eni G., Small, Eric E., and Zreda, Marek
Abstract:: Soil moisture is an essential climate variable influencing land–atmosphere interactions, an essential hydrologic variable impacting rainfall–runoff processes, an essential ecological variable regulating net ecosystem exchange, and an essential agricultural variable constraining food security. Large-scale soil moisture monitoring has advanced in recent years, creating opportunities to transform scientific understanding of soil...

Enlargement of canopy gaps associated with a fungal pathogen in Yosemite Valley, California

Creator:: Rizzo, D. M., Slaughter, G. W., and Parmeter, J. R.
Abstract:: The enlargement of 21 canopy gaps associated with the root pathogen Heterobasidion annosum (Fr.:Fr.) Bref. (; Fomes annosus (Fr.) Karst.) in the mixed-conifer forest of Yosemite Valley was monitored between 1971 and 1998. Mean expanded gap area was 232 m2 (range 38–802 m2) in 1971 and 1455 m2 (range 150–4216...

Short-term responses of native bees to livestock and implications for managing ecosystem services in grasslands

Creator:: Kimoto, Chiho, DeBano, Sandra J., Thorp, Robbin W., Taylor, Robert V., Schmalz, Heidi, DelCurto, Timothy, Johnson, Tracey, Kennedy, Patricia L., and Rao, Sujaya
Abstract:: Rangelands are significant providers of ecosystem services in agroecosystems world‐wide. Yet few studies have investigated how different intensities of livestock grazing impact one important provider of these ecosystem services—native bees. We conducted the first large‐scale manipulative study on the effect of a gradient of livestock grazing intensities on native bees...

Evaluating the Return in Ecosystem Services from Investment in Public Land Acquisitions

Creator:: Kovacs, Kent, Polasky, Stephen, Nelson, Erik, Keeler, Bonnie L., Pennington, Derric, Plantinga, Andrew J., and Taff, Steven J.
Abstract:: We evaluate the return on investment (ROI) from public land conservation in the state of Minnesota, USA. We use a spatially-explicit modeling tool, the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST), to estimate how changes in land use and land cover (LULC), including public land acquisitions for conservation, influence...

Plethodontid Salamander Distributions in Managed Forest Headwaters in Western Oregon, USA

Creator:: Olson, Deanna H. and Kluber, Matthew R.
Abstract:: We examined terrestrial amphibians in managed headwater forest stands in western Oregon from 1998 to 2009. We assessed: (1) temporal and spatial patterns of species capture rates, and movement patterns with distance from streams and forest management treatments of alternative riparian buffer widths and upland thinning; (2) species survival and...

Nitrification Responses of Soil Ammonia-Oxidizing Archaea and Bacteria to Ammonium Concentrations

Creator:: Giguere, Andrew T., Taylor, Anne E., Myrold, David D., and Bottomley, Peter J.
Abstract:: Although ammonia-oxidizing archaea (AOA) and bacteria (AOB) coexist in most non-acidic agricultural soils, the factors that influence their relative contributions to soil nitrification activity remain unclear. A 2- to 4-d whole soil microcosm assay was developed, utilizing the aliphatic C₈ alkyne 1-octyne to inactivate AOB-driven nitrification activity without impacting AOA...

Measurement Tool for Dynamics of Soil Cracks

Creator:: Stewart, Ryan D., Abou Najm, Majdi R., Rupp, David E., and Selker, John S.
Abstract:: Shrinkage cracks in soil function as a dominant control on the partitioning and distribution of moisture fluxes in the vadose zone. Their dynamics influence moisture balance and control water availability for runoff, deep infiltration, and near-surface storage. We present a new low-cost field instrument to monitor the temporal change in...

Abstract:: n situ soil moisture monitoring networks are critical to the development of soil moisture remote sensing missions as well as agricultural and environmental management, weather forecasting, and many other endeavors. These in situ networks utilize a variety of sensors and installation practices, which confounds the development of a unified reference...
