The Reference Condition: Predicting Benchmarks For Ecological And Water-Quality Assessments, Charles P. Hawkins, John R. Olson, Ryan A. Hill

School of Natural Sciences Faculty Publications and Presentations

Benchmarks provide context and are a critical element of all ecological assessments. Over the last 25 y, hundreds of papers have been published on various aspects of ecological assessments, and most of the analyses described in these papers depend on specifying an ecological benchmark for context. Freshwater scientists and managers usually use reference sites (typically sites in natural or least-disturbed condition) to assess the ecological conditions at other sites. Accurate and precise assessments require that assessed sites be matched with appropriate reference conditions. Two general types of approaches have been proposed to predict reference conditions: classifications based on natural environmental …

Deciphering The Chemical Soup: Using Public Nuisance To Compel Chemical Testing, Albert C. Lin

Notre Dame Law Review

The problem of toxic ignorance plagues modern society. On a daily basis, each of us is exposed to hundreds of chemicals, the vast majority of which have been subject to little or no testing to determine whether they are toxic to humans or the environment. Many of these chemicals may turn out to be harmless. Some, however, may cause cancer, reproductive defects, and other harms. In toto, chemicals are believed to be responsible for tens of thousands of deaths per year. The systematic failure of manufacturers and distributors to test chemical substances is a rational response to marketplace incentives, tort …

Influence Of Functionalized Fullerene Structure On Polymer Photovoltaic Degradation, Brian H. Johnson, Enaanake Allagoa, Robert L. Thomas, Gregory Stettler, Marianne Wallis, Justn H. Peel, Thorsteinn Adalsteinsson, Brian J. Mcnelis, Richard P. Barber Jr.

Physics

The time dependence of device performance has been measured for photocells using blends containing the conjugated polymer, poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) with two different functionalized C60 electron acceptor molecules: commercially available [6,6]-phenyl C61 butyric acid methyl ester (PCBM) or [6,6]-phenyl C61 butyric acid octadecyl ester (PCBOD) produced in this laboratory. Performance was characterized by the short-circuit current output of the devices, with the time dependence of PCBM samples typically degrading exponentially. Variations in the characteristic lifetime of the devices were observed to depend on the molar fraction of the electron acceptor molecules (calculated with respect to the MEH-PPV monomer fraction). In comparison …

Flooding: Response And Recovery, E. Kim Cassel, Donna Bittiker, Sharon Guthmiller

SDSU Extension Special Series

Floods are the most common natural disaster, but not all floods are alike. Regardless of the cause of flooding, disaster planning and preparation will reduce the impact of flooding and enhance response and recovery. In the event of moderate-to-severe flooding, total mitigation may not be possible. If your property has sustained flood damage, the following are issues to consider as you begin cleanup.

Hair Whorls In The Dog (Canis Familiaris), Part Ii: Asymmetries, Lisa M. Tomkins, Paul Mcgreevy

Anatomy Collection

In horses and cattle, hair whorls have been shown to act as a structural marker of reactivity and behavioral lateralization. Few studies on canine whorls have been reported and none have assessed whorl position or direction of flow. This study describes the distribution and characteristics of whorl in each of 10 regions in which whorls are typically located in dogs. Hair whorls were assessed in dogs (n = 120) and were recorded as clockwise or counterclockwise in the cephalic, cervical (dorsal, lateral, ventral), thoracic and brachial axillary, chest, shoulders, elbows, abdominal, and ischiatic regions. Bilateral whorls, including brachial axillary, elbow, …

Measures Of Weight Distribution Of Dairy Cows To Detect Lameness And The Presence Of Hoof Lesions, M. Pastell, L. Hänninen, A. M. De Passillé, J. Rushen

Farm Animal Welfare Collection

There is increasing interest in automated methods of detecting lame cows. Hoof lesion data and measures of weight distribution from 61 lactating cows were examined in this study. Lame cows were identified with different numerical rating scores (NRS) used as thresholds (NRS >3 and NRS ≥3.5) for lameness. The ratio of weight applied to a pair of legs (LWR) when the cow was standing was calculated using a special weigh scale, and the cows were gait scored using a 1 to 5 NRS. Hoof lesions were scored and the cows placed into 1 of 4 mutually exclusive categories of hoof …

Assessment Of Lameness Prevalence And Associated Risk Factors In Dairy Herds In England And Wales, Z. E. Barker, K. A. Leach, H. R. Whay, N. J. Bell, D. C. J. Main

Farm Animal Welfare Collection

Visits were made to 205 dairy farms in England and Wales between October 2006 and May 2007 by 1 or more of 4 researchers. At each visit, all milking cows were locomotion scored (lameness scored) using a 4-point scale (0 = sound locomotion, 1 = imperfect locomotion, 2 = lame, 3 = severely lame). The mean prevalence of lameness (scores 2 and 3) across the study farms was 36.8% (range = 0–79.2%). On each farm, the presence within the housing and grazing environments of commonly reported risks for increased lameness was recorded. Each farmer was interviewed to gauge the ability …

Budget Analysis For A Napa County Vineyard, Christopher Jan Hyde

Agribusiness

This study was undertaken to determine whether farming premium wine grapes can generate profit on a 10 acre site in Napa County, and if farming wine grapes can be a profitable long term investment.

The report utilizes two techniques for analysis of the data. The break-even analysis will be used to determine whether the operation is potentially profitable. Vineyard establishment costs were outlined in and production costs (from year 3 forward) defined. Production costs and grape revenues are weighed to determine net revenues above total costs. Monthly per acre break down of costs demonstrates how vineyard production costs fluctuate during …

Bacteria - The Last Stronghold Of Lamarckism?, William D. Stansfield

Biological Sciences

French naturalist J.B. Lamarck is most commonly known for popularizing the theory that some traits acquired during the life of an organism can be inherited in his 1809 book. German biologist A. Weismann presented evidence in his 1891 book that acquired traits were not heritable in sexually reproducing animals. But so little was known about bacteria that they were considered to be the last stronghold of Lamarckism. The “fluctuation test” of S. Luria and M. Delbrück in 1943 seemed to confirm that Lamarckism in bacteria was indeed dead. This review, however, proposes that today bacteria may be viewed as the …

Effect Of Sand Grain Size On Burrowing Behavior Of Juvenile Pacific Sand Crabs (Emerita Analoga), Natalie A. Lee, Laura M. Melroy

Biological Sciences

Emerita analoga, Pacific coast sand crabs, are an important biological component of the swash zone ecosystem. They have evolved the ability to burrow into sand, and burrowing speed is commonly used as an indicator of performance relevant for fitness in this species. Sand grain size varies among beaches, and crabs may be better adapted to to burrow in some sand types. We performed a completely crossed 3-factor experiment to determine how the sand grain size associated with beach-of-origin and rearing conditions influence burrowing in coarse and fine sand. Crabs from a fine sand beach and a coarse sand beach were …

Mate Choice For Genetic Quality: A Test Of The Heterozygosity And Compatibility Hypotheses In A Lek-Breeding Bird, T.B. Ryder, W.P. Tori, J.G. Blake, B.A. Loiselle, P.G. Parker

Biology Department Faculty Works

Understanding female mate choice in nonresource-based mating systems, where females appear to express strong preferences despite receiving no direct benefits from mate choice, remain a challenge to behavioral ecology. Brown (Brown JL. 1997. A theory of mate choice based on heterozygosity. Behav Ecol. 8:60–65) proposed the “good-genes-as-heterozygosity” hypothesis, which sought to establish the genetic nature of male quality. Despite recent attention, few studies have examined how multiple components of genetic quality influence mate choice in a highly promiscuous mating system such as that of the lekking wire-tailed manakin (Pipra filicauda, Aves: Pipridae). Based on a 4-year study in the Amazon …

Comparative Gene Evolution In Haemosporidian (Apicomplexa) Parasites Of Birds And Mammals, Robert Ricklefs, Diana Outlaw

Biology Department Faculty Works

Haemosporidian parasites of birds and mammals reproduce asexually inside nucleated and nonnucleated host erythrocytes, respectively. Because of these different parasite environments and because bird parasites are paraphyletic, we evaluated whether patterns of parasite molecular evolution differ between host groups. We compared two mitochondrial (mt) genes and one apicoplast gene across mammal Plasmodium, bird Plasmodium, and bird Parahaemoproteus. Using a molecular phylogenetic approach, we show that the parasite mt cytochrome b (cyt b), mt cytochrome oxidase I (COI), and the apicoplast caseinolytic protease C (ClpC) exhibit similar levels of sequence divergence, yet each gene tree presents a strikingly different pattern of …

Stable Isotopic Indicators Of Population Structure And Natal Habitats Of Asian Carps Threatening To Invade The Great Lakes, Darcy R. Ernat, Quinton E. Phelps, Gregory W. Whitledge

Posters

Understanding early-life habitats is crucial for managing non-indigenous large river fishes such as silver carp that are threatening to invade the Great Lakes and may significantly impact economically valuable Great Lakes fisheries. Silver carp inhabiting the upper Illinois River directly below the electrical deterrent barrier (installed on a canal in the Chicago area that connects the Illinois River with Lake Michigan) possess the greatest potential to invade the Great Lakes. However, adult silver carp inhabiting this reach of the Illinois River may have originated from many points throughout the Mississippi River basin (e.g., Illinois River or Middle Mississippi River), and …

The Pseudomonas Syringae Type Iii Effector Hopg1 Targets Mitochondria, Alters Plant Development, And Suppresses Plant Innate Immunity, Anna Block, Ming Guo, Guangyong Li, Christian Elowsky, Thomas Clemente, James R. Alfano

Center for Plant Science Innovation: Faculty Publications

The bacterial plant pathogen Pseudomonas syringae uses a type III protein secretion system to inject type III effectors into plant cells. Primary targets of these effectors appear to be effector-triggered immunity (ETI) and pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI). The type III effector HopG1 is a suppressor of ETI that is broadly conserved in bacterial plant pathogens. Here we show that HopG1 from P. syringae pv. tomato DC3000 also suppresses PTI. Interestingly, HopG1 localizes to plant mitochondria, suggesting that its suppression of innate immunity may be linked to a perturbation of mitochondrial function. While HopG1 possesses no obvious mitochondrial signal …

Alkylresorcinol Synthases Expressed In Sorghum Bicolor Root Hairs Play An Essential Role In The Biosynthesis Of The Allelopathic Benzoquinone Sorgoleone, Daniel Cook, Agnes M. Rimando, Thomas E. Clemente, Joachim Schroder, Franck E. Dayan, N. P. Dhammika Nanayakkara, Zhiqiang Pan, Brice P. Noonan, Mark Fishbein, Ikuro Abe, Stephen O. Duke, Scott R. Baerson

Center for Plant Science Innovation: Faculty Publications

Sorghum bicolor is considered to be an allelopathic crop species, producing phytotoxins such as the lipid benzoquinone sorgoleone, which likely accounts for many of the allelopathic properties of Sorghum spp. Current evidence suggests that sorgoleone biosynthesis occurs exclusively in root hair cells and involves the production of an alkylresorcinolic intermediate (5-[(Z,Z)-8',11',14'-pentadecatrienyl]resorcinol) derived from an unusual 16:3D^9,12,15 fatty acyl-CoA starter unit. This led to the suggestion of the involvement of one or more alkylresorcinol synthases (ARSs), type III polyketide synthases (PKSs) that produce 5-alkylresorcinols using medium to long-chain fatty acyl-CoA starter units via iterative condensations with malonyl-CoA. In an effort …

The Expressed Emotion Of Mothers Of Children With Fragile X Syndrome, Jeanine M. Coleman

Electronic Theses and Dissertations

A review of the literature revealed that mothers with children with fragile X syndrome (FXS) face many challenges, including managing their child's behavior which is a defining characteristic of children with FXS (Epstein, Riley, & Sobesky, 2002). Parents and professionals have become increasingly aware through research and everyday experiences that children with FXS are often overly sensitive to multiple stimuli (Hagerman, 1999; Hagerman & Hagerman, 2002; Miller et al., 1999). This overstimulation often leads to behavioral challenges that are characterized by tantrums, angry outbursts, and other forms of aggression. Additionally, mothers of children with FXS have their own personal challenges …
