Dormancy and Germination Pre-treatments in Willamette Valley Native Plants

Creator:: Russell, Michael
Abstract:: Seeds from 30 species of grasses and forbs native to Pacific Northwest prairies were tested for physical and physiological dormancy. The physical dormancy was determined by mechanically and chemically scarifying seeds. Physiological dormancy was evaluated with cold stratification before germination. Experiments were analyzed individually with ANOVA analysis, and by seed...

A new species of western Atlantic lizardfish (Teleostei: Synodontidae: Synodus) and resurrection of Synodus bondi Fowler, 1939, as a valid species from the Caribbean with redescriptions of S. bondi, S. foetens (Linnaeus, 1766), and S. intermedius (Agassiz, 1829)

Creator:: Frable, Benjamin W., Baldwin, Carole C., Luther, Brendan M., and Weigt, Lee A.
Abstract:: Western Atlantic synodontid species were studied as part of an ongoing effort to reanalyze Caribbean shorefish diversity. A neighbor-joining tree constructed from cytochrome c oxidase I (COI) data revealed 2 highly divergent genetic lineages within both Synodus intermedius (Agassiz, 1829) (Sand Diver) and S. foetens (Linnaeus, 1766) (Inshore Lizardfish). A...

Electronic properties of BaCuChF (Ch = S,Se,Te) surfaces and BaCuSeF/ZnPc interfaces

Creator:: Zakutayev, Andriy, Tate, Janet, Platt, Heather A. S., Keszler, Douglas A., Hein, Corinna, Mayer, Thomas, Klein, Andreas, and Jaegermann, Wolfram
Abstract:: BaCuChF (Ch=S,Se,Te) surfaces and BaCuSeF interfaces with zinc phthalocyanine (ZnPc) were studied by photoelectron spectroscopy. BaCuChF compounds oxidize when exposed to ambient atmosphere. Se capping layers were studied as a means to produce representative surfaces for photoelectron spectroscopic measurements. Decapped BaCuSeF surfaces remain O-free and C-free when the Se layer...

Observations of Stratocumulus Clouds and Their Effect on the Eastern Pacific Surface Heat Budget along 20 degrees S

Creator:: de Szoeke, Simon P., Yuter, Sandra, Mechem, David, Fairall, Chris W., Burleyson, Casey D., and Zuidema, Paquita
Abstract:: Widespread stratocumulus clouds were observed on nine transects from seven research cruises to the southeastern tropical Pacific Ocean along 20°S, 75°–85°W in October–November of 2001–08. The nine transects sample a unique combination of synoptic and interannual variability affecting the clouds; their ensemble diagnoses longitude–vertical sections of the atmosphere, diurnal cycles...

Camelina: Seed Yield Response to Applied Nitrogen and Sulfur

Creator:: Wysocki, Donald J., Chastain, Thomas G., Schillinger, William F., Guy, Stephen O., and Karow, Russell S.
Abstract:: Camelina (Camelina sativa L. Crantz) has received worldwide attention in recent years as a biofuel crop and as a broadleaf option in cereal-based cropping systems. The objective of our 3-year study was to determine camelina seed yield and nitrogen use efficiency (NUE) as affected by six applied nitrogen (N) rates...

Camelina: Planting date and method effects on stand establishment and seed yield

Creator:: Schillinger, William F., Wysocki, Donald J., Chastain, Thomas G., Guy, Stephen O., and Karow, Russell S.
Abstract:: There has been keen interest in camelina (Camelina sativa L. Crantz) in recent years due to the unique fatty acid composition of the seed oil for human and animal consumption and, more importantly, the value of the seed oil to provide “green energy” to fuel commercial and military aircraft. The...

Directional output distance functions: endogenous directions based on exogenous normalization constraints

Creator:: Färe, Rolf, Grosskopf, S., and Whittaker, G.
Abstract:: In response to a question raised by Knox Lovell, we develop a method for estimating directional output distance functions with endogenously determined direction vectors based on exogenous normalization constraints. This is reminiscent of the Russell measure proposed by Färe and Lovell (J Econ Theory 19:150–162, 1978). Moreover it is related...

Assessment of the Carbonate Chemistry Seasonal Cycles in the Southern Ocean From Persistent Observational Platforms

Creator:: Williams, N. L., Juranek, L. W., Feely, R. A., Russell, J. L., Johnson, K. S., and Hales, B.
Abstract:: Observations from Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) biogeochemical profiling Argo floats are used to characterize the climatological seasonal cycles and drivers of dissolved inorganic carbon, total alkalinity, pH, the partial pressure of carbon dioxide (CO2), and the saturation state of aragonite at the surface and at...

Drone Up! Quantifying Whale Behavior From a New Perspective Improves Observational Capacity

Creator:: Lemos, Leila, Chandler, Todd E., Torres, Leigh G., and Nieukirk, Sharon L.
Abstract:: During traditional boat-based surveys of marine megafauna, behavioral observations are typically limited to records of animal surfacings obtained from a horizontal perspective. Achieving an aerial perspective has been restricted to brief helicopter or airplane based observations that are costly, noisy, and risky. The emergence of commercial small unmanned aerial systems...

Using Cure Models for Analyzing the Influence of Pathogens on Salmon Survival

Creator:: Ray, R. Adam, Perry, Russell W., Som, Nicholas A., and Bartholomew, Jerri L.
Abstract:: Parasites and pathogens influence the size and stability of wildlife populations, yet many population models ignore the population-level effects of pathogens. Standard survival analysis methods (e.g., accelerated failure time models) are used to assess how survival rates are influenced by disease. However, they assume that each individual is equally susceptible...
