Catchment-Scale Modeling of Nitrogen Dynamics in a Temperate Forested Watershed, Oregon. An Interdisciplinary Communication Strategy

Creator:: Vaché, Kellie, Breuer, Lutz, Jones, Julia A., and Sollins, Phil
Abstract:: We present a systems modeling approach to the development of a place-based ecohydrological model. The conceptual model is calibrated to a variety of existing observations, taken in watershed 10 (WS10) at the HJ Andrews Experimental Forest (HJA) in Oregon, USA, a long term ecological research (LTER) site with a long...

A Primer on Peroxiredoxin Biochemistry

Creator:: Karplus, P. Andrew
Abstract:: Peroxiredoxins (Prxs) were not recognized as a family of enzymes until the 1990s but are now known to be the dominant peroxidases in most organisms. Here, the history and fundamental properties of peroxiredoxins are briefly reviewed, with a special focus on describing how an exquisitely tunable balance between fully folded...

Flour Quality and Artisan Bread

Creator:: Ross, Andrew S.
Abstract:: A technical definition of artisan breads is proposed, based on the concepts of lean formulations, long fermentations, and the use of process as the primary way to adapt to changing flour qualities. The current status of what constitutes refined flour for artisan bread production is presented and a conclusion drawn...

TOPEX/POSEIDON tides estimated using a global inverse model

Creator:: Egbert, Gary D., Bennett, Andrew F., and Foreman, Michael G. G.
Abstract:: Altimetric data from the TOPEX/POSEIDON mission will be used for studies of global ocean circulation and marine geophysics. However, it is first necessary to remove the ocean tides, which are aliased in the raw data. The tides are constrained by two distinct types of information: the hydrodynamic equations which the...

Mixed-conifer forests of central Oregon: effects of logging and fire exclusion vary with environment

Creator:: Merschel, Andrew G., Spies, Thomas A., and Heyerdahl, Emily K.
Abstract:: Twentieth-century land management has altered the structure and composition of mixed-conifer forests and decreased their resilience to fire, drought, and insects in many parts of the Interior West. These forests occur across a wide range of environmental settings and historical disturbance regimes, so their response to land management is likely...

Yellow nutsedge (Cyperus esculentus) Growth and Tuber Production in Response to Increasing Glyphosate Rates and Selected Adjuvants

Creator:: Felix, Joel, Dauer, Joseph T., Hulting, Andrew G., and Mallory-Smith, Carol
Abstract:: Greenhouse studies were conducted to evaluate the influence of selected adjuvants on glyphosate efficacy on yellow nutsedge and tuber production. Glyphosate was applied at 0, 0.25, 0.43, 0.87, 1.26 (1x rate), and 1.74 kg ae ha⁻¹ 31 d after yellow nutsedge was planted. Each rate was mixed with one of...

Hypersaline “wet patches” in Taylor Valley, Antarctica

Creator:: Levy, Joseph S., Fountain, Andrew G., Welch, Kathy A., and Lyons, W. Berry
Abstract:: Spatially isolated patches of soil located in Taylor Valley, McMurdo Dry Valleys, Antarctica, are sites of elevated salt content and soil moisture. During Antarctic spring, in the absence of snow melt, visibly wet (reduced albedo) patches of soil are present at the surface. The soil pore fluids are hypersaline and...

Characterizing neutral and adaptive genomic differentiation in a changing climate: The most northerly freshwater fish as a model

Creator:: O'Malley, Kathleen G., Vaux, Felix, and Black, Andrew N.
Abstract:: Arctic freshwater ecosystems have been profoundly affected by climate change. Given that the Arctic charr (Salvelinus alpinus) is often the only fish species inhabiting these ecosystems, it represents a valuable model for studying the impacts of climate change on species life‐history diversity and adaptability. Using a genotyping‐by‐se‐ quencing approach, we...

Wild bee diversity is enhanced by experimental removal of timber harvest residue within intensively managed conifer forest

Creator:: Rivers, James W., Mathis, Codey L., Moldenke, Andrew R., and Betts, Matthew G.
Abstract:: The use of timber harvest residue as an energy source is thought to have environmental benefits relative to food-based crops, yet the ecological impact of this practice remains largely unknown. We assessed whether the abundance and diversity of wild bees (Apoidea) were influenced by the removal of harvest residue and...

Relationship Between Wildfire, Salvage Logging, and Occupancy of Nesting Territories by Northern Spotted Owls

Creator:: Clark, Darren A., Anthony, Robert G., and Andrews, Lawrence S.
Abstract:: The northern spotted owl (Strix occidentalis caurina) is one of the most intensively studied raptors in the world; however, little is known about the impacts of wildfire on the subspecies and how they use recently burned areas. Three large-scale wildfires in southwest Oregon provided an opportunity to investigate the short-term...
