Trends in cation, nitrogen, sulfate and hydrogen ion concentrations in precipitation in the United States and Europe from 1978 to 2010: a new look at an old problem

Creator:: Lajtha, Kate and Jones, Julia A.
Abstract:: Industrial emissions of SO₂ and NOₓ, resulting in the formation and deposition of sulfuric and nitric acids, affect the health of both terrestrial and aquatic ecosystems. Since the mid-late 20th century, legislation to control acid rain precursors in both Europe and the US has led to significant declines in both...

Fingered Flow in Two Dimensions 2. Predicting Finger Moisture Profile

Creator:: Selker, J., Parlange, J.-Y., and Steenhuis, T.
Abstract:: An exact integral solution for the moisture profile in growing fingers in sandy soil is derived from Richards' equation. The solution provides moisture content along a finger as a function of position and time and provides applicable results, including the calculation of the asymptotic matric potential of a growing finger...

Density fractionation and 13C reveal changes in soil carbon following woody encroachment in a desert ecosystem

Creator:: Throop, Heather L., Lajtha, Kate, and Kramer, Marc
Abstract:: Woody encroachment has dramatically changed land cover patterns in arid and semiarid systems (drylands) worldwide over the past 150 years. This change is known to influence bulk soil carbon (C) pools, but the implications for dynamics and stability of these pools are not well understood. Working in a Chihuahuan Desert...

Linking aboveground net primary productivity to soil carbon and dissolved organic carbon in complex terrain

Creator:: Peterson, Fox S. and Lajtha, Kate J.
Abstract:: Factors influencing soil organic matter (SOM) stabilization and dissolved organic carbon (DOC) content in complex terrain, where vegetation, climate, and topography vary over the scale of a few meters, are not well understood. We examined the spatial correlations of lidar and geographic information system-derived landscape topography, empirically measured soil characteristics,...

Thermal reaction norms for growth vary among cohorts of Pacific cod (Gadus macrocephalus)

Creator:: Hurst, Thomas P., Munch, Stephan B., and Lavelle, Kate A.
Abstract:: While much effort has been directed at determining the spatial scales of adaptation in thermal reaction norms for growth, it is widely assumed that these reaction norms have high temporal stability. Water temperatures in the Gulf of Alaska in 2007 were the coldest on record since the mid-1970s and we...

Involving the users remotely : an exploratory study using asynchronous usability testing

Creator:: Filar Williams, Beth and Valla, Sara
Abstract:: Open Educational Resources (OER) are increasingly used in the higher education landscape as a solution for a variety of copyright, publishing and cost-prohibiting issues. While OERs are becoming more common, reports of usability tests that evaluate how well learners can use them to accomplish their learning tasks have lagged behind....

Landsat-based monitoring of annual wetland change in the Willamette Valley of Oregon, USA from 1972 to 2012

Creator:: Fickas, Kate C., Cohen, Warren B., and Yang, Zhiqiang
Abstract:: n Oregon’s Willamette Valley, remaining wetlands are at high risk to loss and degradation from agricultural activity and urbanization. With an increased need for fine temporal-scale monitoring of sensitive wetlands, we used annual Landsat MSS and TM/ETM+ images from 1972 to 2012 to manually interpret loss, gain, and type conversion...

Growth and distributional correlates of behavior in three co-occurring juvenile flatfishes

Creator:: Ryer, Clifford H., Boersma, Kate S., and Hurst, Thomas P.
Abstract:: We explored whether anti-predator behavior and intrinsic growth are co-evolved traits in 3 co-occurring juvenile flatfish species: English sole Pleuronectes vetulus, Pacific halibut Hippoglossus stenolepis and northern rock sole Lepidopsetta polyxystra. English sole are risk prone, adopting behavior that renders them more vulnerable to predation, while northern rock sole are...

Manipulating Soil Moisture and Nitrogen Availability Part II. Fermentable Nitrogen Content and Must and Wine Composition

Creator:: Watson, Barney, Wall, Kate, Specht, Anna, Chen, Hsiao-Ping, and McDaniel, Mina
Abstract:: An approximation of the total yeast fermentable nitrogen content in juice or must is taken as the sum of the nitrogen available from ammonia and the alpha-amino acids present (Bisson 1991 ; Dukes and Butzke 1998 ; Jiranek, Langridge, and Henshcke 1995). Recommended levels of fermentable nitrogen needed by yeast...

Beyond Peer-Reviewed Articles: Using Blogs to Enrich Students' Understanding of Scholarly Work

Creator:: Deitering, Anne-Marie and Gronemyer, Kate
Abstract:: Undergraduate students are expected to find, evaluate and use peer-reviewed or scholarly literature, but they rarely learn about the process of creating new knowledge or the roles the literature plays in the work of scholars. A desired outcome of undergraduate education is the understanding that knowledge is created, evolving and...
