Dividing up the pie: Whales, fish, and humans as competitors

Creator:: Ruzicka, James J., Steele, John H., Ballerini, Tosca, Gaichas, Sarah K., and Ainley, David G.
Abstract:: Similarly structured food web models of four coastal ecosystems (Northern California Current, Central Gulf of Alaska, Georges Bank, southwestern Antarctic Peninsula) were used to investigate competition among whales, fishes, pinnipeds, and humans. Two analysis strategies simulated the effects of historic baleen and odontocete whale abundances across all trophic levels: food...

Analysis of Energy Flow in US GLOBEC Ecosystems Using End-to-End Models

Creator:: Ruzicka, James J., Steele, John H., Gaichas, Sarah K., Ballerini, Tosca, Gifford, Dian J., Brodeur, Richard D., and Hofmann, Eileen E.
Abstract:: End-to-end models were constructed to examine and compare the trophic structure and energy flow in coastal shelf ecosystems of four US Global Ocean Ecosystem Dynamics (GLOBEC) study regions: the Northern California Current, the Central Gulf of Alaska, Georges Bank, and the Southwestern Antarctic Peninsula. High-quality data collected on system components...

... as Forage in the Ecosystem: The Demand for Ecosystem Valuation

Creator:: Lee, Min-Yang, Deroba, Jonathan, Gaichas, Sarah, Feeney, Rachel G., Boelke, Deirdre, and Irwin, Brian
Abstract:: Birds, mammals, and fish eat Atlantic Herring. For the first time, fisheries managers in New England are explicitly considering these, and other, predators when setting harvest control rules for the Atlantic Herring fishery. Based on single-species biological reference points, the herring stock is currently well above MSY levels. However, management...

Sarah Wright Poster 2012.pdf

Creator:: Wright, Sarah K.
Abstract:: The Willamette Valley, west of the Cascade mountain range in the state of Oregon, is home to a growing number of vineyards. This rather recent, booming industry of the region has become an important component of the economy of the state’s agriculture since the late 1960’s, contributing more than $1.56...

Ammonia Volatilization from Nitrogen Fertilizers and Wastewater Reuse in the Columbia Basin

Creator:: Del Moro, Sarah K.
Abstract:: Ammonia (NH₃) volatilization and loss from nitrogen (N) fertilizer in agriculture negatively impacts crops, farm profitability, human health and surrounding ecosystems where it is deposited. A significant source of NH₃ volatilization occurs from surface application of urea on sandy soils with low pH buffering capacity such as those in the...

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...

Using interactive technology to improve health : is weight loss just a mouse-click away?

Creator:: Grall, Sarah K.
Abstract:: Since 1980, the prevalence of obesity among U.S. adults has more than doubled, accompanied by increases in chronic conditions like heart disease and diabetes. This high prevalence and associated disease burden continues to be a threat to public health. Despite years of efforts to stem the tide of obesity, successful...
