Top-Down Effects of Wildlife and Bottom-Up Drivers of Soils and Productivity in Intensively Managed Forest Plantations in the Northern Oregon Coast Range

Creator:: Frey, David W.
Abstract:: In intensively managed forest plantations in the northern Oregon Coast Range, herbicides are often applied during site preparation and early stand regeneration to reduce competition for resources for planted conifer seedlings. In addition to reducing competition for crop trees, herbicide applications may affect soil processes including decomposition and nutrient cycling,...

Post-fire logging produces minimal persistent impacts on understory vegetation in northeastern Oregon, USA

Creator:: Peterson, David W. and Dodson, Erich Kyle
Abstract:: Post-fire forest management commonly requires accepting some negative ecological impacts from management activities in order to achieve management objectives. Managers need to know, however, whether ecological impacts from post-fire management activities are transient or cause long-term ecosystem degradation. We studied the long-term response of understory vegetation to two post-fire logging...

Estimating the Counterfactual Impact of Conservation Programs on Land Cover Outcomes: The Role of Matching and Panel Regression Techniques

Creator:: Jones, Kelly W. and Lewis, David J.
Abstract:: Deforestation and conversion of native habitats continues to be the leading driver of biodiversity and ecosystem service loss. A number of conservation policies and programs are implemented—from protected areas to payments for ecosystem services (PES)—to deter these losses. Currently, empirical evidence on whether these approaches stop or slow land cover...

Effect of forecast skill on management of the Oregon coast coho salmon (Oncorhynchus kisutch) fishery

Creator:: Rupp, David E., Wainwright, Thomas C., and Lawson, Peter W.
Abstract:: Better fisheries management is often given as one justification for research on improving forecasts of fish survival. However, the value gained from expected improvements in forecast skill in terms of achieving management goals is rarely quantified as part of research objectives. Using Monte Carlo simulations of population dynamics, we assessed...

Impact of season-long water abstraction on invertebrate drift composition and concentration

Creator:: Wooster, David, Miller, Scott W., and DeBano, Sandra J.
Abstract:: Surface water abstraction from rivers for irrigated agriculture is one of the largest uses of freshwater resources in the world. Water abstraction has important impacts on the structure of riverine assemblages. However, little work has examined the chronic, season-long impacts on ecosystem functions. Invertebrate drift is an important ecosystem function...

Theoretical Prediction of Disrupted Min Oscillation in Flattened Escherichia coli

Creator:: Schulte, Jeff B., Zeto, Rene W., and Roundy, David
Abstract:: The dynamics of the Min-protein system help Escherichia coli regulate the process of cell division by identifying the center of the cell. While this system exhibits robust bipolar oscillations in wild-type cell shapes, recent experiments have shown that when the cells are mechanically deformed into wide, flattened out, irregular shapes,...

Seasonal Climate Variability and Change in the Pacific Northwest of the United States

Creator:: Abatzoglou, John T., Rupp, David E., and Mote, Philip W.
Abstract:: Observed changes in climate of the U.S. Pacific Northwest since the early twentieth century were examined using four different datasets. Annual mean temperature increased by approximately 0.6°–0.8°C from 1901 to 2012, with corroborating indicators including a lengthened freeze-free season, increased temperature of the coldest night of the year, and increased...

Toward genome-enabled mycology

Creator:: Hibbett, David S., Stajich, Jason E., and Spatafora, Joseph W.
Abstract:: Genome-enabled mycology is a rapidly expanding field that is characterized by the pervasive use of genome-scale data and associated computational tools in all aspects of fungal biology. Genome-enabled mycology is integrative and often requires teams of researchers with diverse skills in organismal mycology, bioinformatics and molecular biology. This issue of...

An Experimental Study on the Effect of Pattern Recognition Parameters on the Accuracy of Wireless-Based Task Time Estimation

Creator:: Muyanja, Andrew W., Atichat, Tanawat, and Porter, J. David
Abstract:: Task time estimation is a core industrial engineering discipline. However, the process to collect the required data is manually intensive and tedious, thus making it expensive to keep the data current. Radio frequency signals have been used to automate the required data collection in some applications. However, such radio frequency...

Developmental rate: A unifying mechanism for sympatric divergence in postglacial fishes?

Creator:: Mcphee, Megan V., Noakes, David L. G., and Allendorf, Fred W.
Abstract:: Morphologically divergent ecotypes arise in fish populations on postglacial time scales, and resource polymorphisms are often invoked to explain their origin. However, genetic recombination can constrain the ability of divergent selection to produce reproductive isolation in sympatry. Recombination breaks up favorable combinations of traits (”adaptive suites”) if individual traits are...
