Comparing California's Cost Of Regulation To Other States: A Case Study Approach For Agriculture, Lynn Hamilton

Agribusiness

Regulatory pressure is a source of increasing concern for California producers. Though regulations have a positive impact on society in terms of cleaner air and water, as well as increased worker safety; they impose multiple costs to farmers in the state. Growers must comply with a tangle of rules from the local, state and federal levels. Many regional differences arise in California environmental regulations, and regulatory pressure is unevenly applied throughout the state.

Previous studies regarding the regulatory environment in California have quantified the total cost of regulation on the state’s agricultural producers. The goal of this study was to …

Environmental Rearing Conditions Produce Forebrain Differences In Wild Chinook Salmon Oncorhynchus Tshawytscha, R. L. Kihslinger, Sean C. Lema, G. A. Nevitt

Biological Sciences

Recent studies suggest that hatchery-reared fish can have smaller brain-to-body size ratios than wild fish. It is unclear, however, whether these differences are due to artificial selection or instead reflect differences in rearing environment during development. Here we explore how rearing conditions influence the development of two forebrain structures, the olfactory bulb and the telencephalon, in juvenile Chinook salmon (Oncorhynchus tshawytscha) spawned from wild-caught adults. First, we compared the sizes of the olfactory bulb and telencephalon between salmon reared in a wild stream vs. a conventional hatchery. We next compared the sizes of forebrain structures between fish reared …

The Effects Of Carotenoid And Food Availability On Resistance To A Naturally Occurring Parasite (Gyrodactylus Turnbulli) In Guppies (Poecilia Reticulata), Gita R. Kolluru, Gregory F. Grether, Sandra H. South, Eric Dunlop, Andrea Cardinali, Linda Liu, Andreah Carapiet

Biological Sciences

Dietary carotenoids have been shown to confer immunological benefits to some species of animals in which males also use these pigments to attract mates. Thus, the potential exists for an allocation trade-off between the sexual and immunological functions of carotenoids. Food availability may also influence immune system function. The present study examined the effects of carotenoid and food availability on the resistance of male guppies (Poecilia reticulata Peters) from four wild populations to the parasite Gyrodactylus turnbulli Harris. Intermediate levels of carotenoid ingestion resulted in the lowest parasite loads, which suggests that carotenoids strengthen parasite resistance at low levels …

Properties Of Intracellular Magnetite Crystals Produced By Desulfovibrio Magneticus Strain Rs-1, Mihály Pósfai, B. M. Moskowitz, Balázs Arató, Dirk Schüler, Christine Flies, Dennis A. Bazylinski, Richard B. Frankel

Physics

Desulfovibrio magneticus strain RS-1 is an anaerobic sulfate-reducing bacterium. Cells form intracellular nanocrystals of magnetite but are only weakly magnetotactic. In order to understand the unusual magnetic response of this strain, we studied magnetite crystals within cells grown with fumarate and sulfate. Many cells grown under either condition did not form magnetic crystals while others contained only 1 to 18 small (~40 nm) magnetite-containing magnetosomes. Bulk magnetic measurements of whole cells showed a superparamagnetic-like behavior, indicating that many of the magnetite crystals are too small to have a permanent magnetic moment at ambient temperature. The temperature of the Verwey transition …

Testing An Ecophysiological Mechanism Of Morphological Plasticity In Pupfish And Its Relevance To Conservation Efforts For Endangered Devils Hole Pupfish, Sean C. Lema, Gabrielle A. Nevitt

Biological Sciences

Imperiled species that have been translocated or established in captivity can show rapid alterations in morphology and behavior, but the proximate mechanisms of such phenotypic changes are rarely known. Devils Hole pupfish (Cyprinodon diabolis) are endemic to a single desert pool and are characterized by a small body, large head and eyes, and lack of pelvic fins. To lessen the risk of extinction, additional populations of C. diabolis were established in artificial refuges. Yet, pupfish in these refuges rapidly shifted to a larger body, smaller head and eyes, and greater body depth. Here we examined how food availability …

Sustainability At Cal Poly, Facility Services, California Polytechnic State University - San Luis Obispo, Facilities Planning And Capital Projects, California Polytechnic State University - San Luis Obispo, Sustainability Advisory Committee, California Polytechnic State University - San Luis Obispo

Publications

This report is one of many attempts to quantify and track Cal Poly’s movement toward a “greener” campus. Efforts are underway to reduce reliance on automobile commuting to campus, to promote energy and water conservation, to recycle solid waste, and to incorporate “green” products and practices in new buildings and in campus operations. This report looks at measures of sustainability along several parameters. The results not only highlight various successes, but also suggest areas in which additional efforts are needed. We intend to update this report biennially.

The Effect Of Plate Rotation On The Stiffness Of Femoral Liss: A Mechanical Study, Afshin Khalafi, Shane Curtiss, Scott Hazelwood, Philip Wolinsky

Biomedical Engineering

Objective: Malposition of the femoral Less Invasive Stabilization System (LISS) plate may alter its biomechanical behavior. This study compares the mechanical stability of ‘‘correctly’’ affixed LISS plates matching the slope of the lateral femoral condyle to ‘‘incorrectly’’ placed LISS plates fixed in external rotation relative to the distal femur.

Methods: A fracture gap model was created to simulate a comminuted supracondylar femur fracture (AO/OTA33-A3). Fixation was achieved using two different plate positions: the LISS plate was either placed ‘‘correctly’’ by internally rotating the plate to match the slope of the lateral femoral condyle, or ‘‘incorrectly’’ by externally rotating the plate …

Crystal Habits And Magnetic Microstructures Of Magnetosomes In Coccoid Magnetotactic Bacteria, Ulysses Lins, Martha R. Mccartney, Marcos Farina, Richard B. Frankel, Peter R. Buseck

Physics

We report on the application of off-axis electron holography and high-resolution TEM to study the crystal habits of magnetosomes and magnetic microstructure in two coccoid morphotypes of magnetotactic bacteria collected from a brackish lagoon at Itaipu, Brazil. Itaipu-1, the larger coccoid organism, contains two separated chains of unusually large magnetosomes; the magnetosome crystals have roughly square projections, lengths up to 250 nm and are slightly elongated along [111] (width/length ~ 0.9). Itaipu-3 magnetosome crystals have lengths up to 120 nm, greater elongation along [111] (width/length approximately 0.6), and prominent corner facets. The results show that Itaipu-1 and Itaipu-3 magnetosome crystal …

Modes Of Biomineralization Of Magnetite By Microbes, Dennis A. Bazylinski, Richard B. Frankel, Kurt O. Konhauser

Physics

Biomineralization processes have traditionally been grouped into two distinct modes; biologically induced mineralization (BIM) and biologically controlled mineralization (BCM). In BIM, microbes cause mineral formation by sorbing solutes onto their cell surfaces or extruded organic polymers and/or releasing reactive metabolites which alter the saturation state of the solution proximal to the cell or polymer surface. Such mineral products appear to have no specific recognized functions. On the other hand, in BCM microbes exert a great degree of chemical and genetic control over the nucleation and growth of mineral particles, presumably because the biominerals produced serve some physiological function. Interestingly, there …
