Photoacclimation of natural phytoplankton communities

Creator:: Graff, Jason R., Westberry, Toby K., Milligan, Allen J., Brown, Matthew B., Dall’Olmo, Giorgio, Reifel, Kristen M., and Behrenfeld, Michael J.
Abstract:: ABSTRACT: Phytoplankton regulate internal pigment concentrations in response to light and nutrient availability. Chlorophyll a to phytoplankton carbon ratios (chl:C phyto) are commonly reported as a function of growth irradiance (Eg) for evaluating the photoacclimation response of phytoplankton. In contrast to most culture experiments, natural phytoplankton communities experience fluctuating environmental...

Sethoxydim herbicide in red fescue and bentgrass : levels and mechanisms of selectivity

Creator:: Butler, J. Hugh B.
Abstract:: The herbicide rate required to reduce growth by 50% (GR₅₀) of 11 cultivars of red fesue (Festuca rubra L. and F. rubra ssp. commutata) and for four cultivars of bentgrass (Agrostis tenuis Sibth. and A. stolonifera L. var. palustris) to sethoxydim (2-[1-(ethoxyimino) butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one) was determined in greenhouse and laboratory experiments....

The timber harvesting behavior of family forest owners

Creator:: Butler, Brett J.
Abstract:: To increase our understanding of the timber harvesting behavior of family forest owners, I developed theoretical and empirical timber harvesting models for family forest owners in the southeastern United States. An individual-choice model was the basis for the models. Family forest owners were modeled as utility-maximizers who made harvesting decisions...

Silviculture and reserve impacts on potential fire behavior and forest conservation: twenty-five years of experience from Sierra Nevada mixed conifer forests

Creator:: Stephens, Scott L. and Moghaddas, Jason J.
Abstract:: Most administrators and ecologists agree that reducing the levels of hazardous fuels on forests is essential to restore healthy watersheds and protect adjacent human communities. The current debate over the appropriateness, technique, and timing of treatments utilized to restore vegetation structure and composition is currently on-going at local, state, and...

Chlamydiae under stress : environmental conditions influence the production and localization of chlamydial antigens

Creator:: Brown, Wendy J.
Abstract:: Chlamydiae are obligate intracellular pathogens that cause several serious conditions within the human host. Many of the symptoms associated with infection are thought to stem from the development of aberrant, or persistent, chlamydiae. Factors leading to chlamydial persistence include deprivation of amino acids, the release of certain cellular factors, or...

Spatiotemporal Characterization of Sclerotinia Crown Rot Epidemics in Pyrethrum

Creator:: Scott, Jason B., Gent, David H., Pethybridge, Sarah J., and Hay, Frank S.
Abstract:: Sclerotinia crown rot, caused by Sclerotinia minor and S. sclerotiorum, is a disease of pyrethrum in Australia that may cause substantial decline in plant density. The spatiotemporal characteristics of the disease were quantified in 14 fields during three growing seasons. Fitting the binary power law to disease incidence provided slope...

Evaluating the influence of land use, drought and reach isolation on the occurrence of freshwater mussel species in the lower Flint River Basin, Georgia (U.S.A.)

Creator:: Shea, Colin P., Peterson, James T., Conroy, Michael J., and Wisniewski, Jason M.
Abstract:: North American freshwater mussels have been subjected to multiple stressors in recent decades that have contributed to declines in the status and distribution of many species. However, considerable uncertainty exists regarding the relative influence of these factors on observed population declines. 2. We used an occupancy modelling approach to quantify...

Field evaluation of passive capillary samplers for estimating groundwater recharge

Creator:: Louie, Michael J., Shelby, Patrick M., Smesrud, Jason S., Gatchell, Lance O., and Selker, John S.
Abstract:: Passive capillary samplers (PCAPS), which sample water from the vadose zone via a hanging water column in a fiberglass wick, have shown potential to provide superior estimates of soil water flux compared to alternative methods. The objectives of this study were to evaluate the performance of PCAPS under natural rain-fed...

Efficient data-parallel files via automatic mode detection

Creator:: Oregon State University. Dept. of Computer Science, Moore, Jason Andrew, Hatcher, Philip J., and Quinn, Michael J. (Michael Jay)
Abstract:: Parallel languages rarely specify parallel I/O constructs, and existing commercial systems provide the programmer with a low-level I/O interface. We present design principles for integrating I/O into languages and show how these principles are applied to a virtual-processor-oriented language. We show how machine-independent modes are used to support both high...
