Efficacy of entomopathogenic fungi for control of the cabbage maggot, Delia radicum (L.) (Diptera: Anthomyiidae)

Creator:: Snelling, Jane E.
Abstract:: The cabbage maggot, Delia radicum (L.) (Diptera: Anthomyiidae) is a serious pest of cruciferous crops (i.e. broccoli, cabbage, turnip, rutabaga) in North America and Europe (Coaker and Finch, 1971; Whistlecraft et al., 1985). The adult flies lay eggs around the base and in cracks at the soil surface around wild...

Epifaunal density differences on coralline algae compared to fleshy algae in the Yachats, Oregon intertidal community

Creator:: Gani, Christopher D.
Abstract:: Ocean acidification has led to many issues regarding the decline of calcifying organisms, such as coralline algae. Acidified sea water inhibits precipitation of CaCO3 that affects the structure and growth of coralline algae. Therefore, non-calcifying algae may outcompete calcifying algae in the intertidal systems with future acidic ocean condition. Variety...

Automated annotation of Caenorhabditis mitochondrial genomes and phylogenetic analysis

Creator:: Campbell, Jessica L.
Abstract:: Motivation Relatively little is known about the evolution of mitochondrial genomes between Caenorhabditis species despite decades of research. Both the worldwide search for new nematode species and the effort to increase sequencing speeds require automated tools to quickly characterize and categorize large amounts of data. Results We developed an automated...

Comparison of the Accuracy and Applicability of Forebody Wake Effect Models for Parachute System Design

Creator:: Kemling, Gabriel H. and Blunck, David L.
Abstract:: The forebody wake effect (FWE) is important to consider when designing parachute systems because it can affect parachute performance. Parachutes work by altering the aerodynamic properties of an attached forebody to control a descent. The FWE can reduce parachute drag, causing the system to descend faster than desired. This drag...

Constraining the origin and influence of andesite in the Purico ignimbrite, N. Chile

Creator:: Lapinski, Sarah L.
Abstract:: A feature of large continental magmatic systems is voluminous dacite ignimbrites erupted from upper crustal magma reservoirs. In the Altiplano Puna Volcanic Complex (APVC) of the Central Andes, a major ignimbrite and caldera plateau, magma systems are found to be long-lived and remarkably homogeneous requiring that they be maintained by...

Constraining Upper Crustal Magmas in the North Chilean Andes

Creator:: Lewis, Charles T.
Abstract:: The 4.59-4.18 Ma Caspana ignimbrite, found within the Altiplano-Puna Volcanic Complex (APVC), is the result of an ~8km3 eruption that took place during the Neogene Ignimbrite Flare-up in the N. Chilean Andes. While most of the eruptions during this flare up are large, monogenetic eruptions, the Caspana that is characterized...

Kale, as a Winter Food for Swine

Creator:: Sprague, Claude Bates
Abstract:: "In conclusion it may be said that kale is almost a winter maintenance ration for swine, but when fed in addition with a little grain or skim milk, good growths will be made. Especially is this true of young pigs as is denoted by the tables. Taking all in all,...

Ingestion of Microplastics in the Juvenile Black Rockfish (Sebastes melanops) from Oregon Coastal Sampling Sites

Creator:: Arnold, Madison A.
Abstract:: Microplastics (<5mm) are a ubiquitous environmental pollutant that have the potential to cause significant harm in many fish species. Therefore, understanding the quantities at which they are being consumed by living organisms is crucial for characterizing risk. There are currently gaps in the microplastic literature regarding microplastic data from finfish...

Whole system perspective : Steelhead, Onchorhynchus mykiss, glutathione s-transferase as a biomarker of chlorpyrifos exposure

Creator:: Pecore, Rachael G.
Abstract:: Organophosphate insecticides may produce sublethal, adverse effects on salmonid growth, reproduction, maturation, swimming, and feeding. Chlorpyrifos, an organophosphate insecticide, was detected by the Oregon Department of Environmental Quality in the Hood River and tributaries during March 1999 at levels exceeding state water quality standards in the range of 0.011-0.482 μg/L....
