Seed Dispersal By Pulp Consumers, Not ‘‘Legitimate’’ Seed Dispersers, Increases Guettarda Viburnoides Population Growth, Andrea P. Loayza, Tiffany M. Knight

Biology Faculty Research

We examined the effect of seed dispersal by Purplish Jays (Cyanocorax cyanomelas; pulp consumers) and the Chestnut-eared Araçari (Pteroglossus castanotis; "legitimate" seed dispersers) on population growth of the small tree Guettarda viburnoides (Rubiaceae) in northeastern Bolivian savannas. Because each bird species differs with respect to feeding and post-feeding behavior, we hypothesized that seed dispersal by each species will contribute differently to the rate of increase of G. viburnoides, but that seed dispersal by either species will increase population growth when compared to a scenario with no seed dispersal. To examine the effects of individual dispersers on the future population size …

Chapter 27 – Studying Plus-End Tracking At Single Molecule Resolution Using Tirf Microscopy, Ram Dixit, Jennifer L. Ross

Biology Faculty Research

The highly dynamic microtubule plus-ends are key sites of regulation that impact the organization and function of the microtubule cytoskeleton. Much of this regulation is performed by the microtubule plus-end tracking (+TIP) family of proteins. +TIPs are a structurally diverse group of proteins that bind to and track with growing microtubule plus-ends in cells. +TIPs regulate microtubule dynamics as well as mediate interactions between microtubule tips and other cellular structures. Most +TIPs can directly bind to microtubules in vitro; however, the mechanisms for their plus-end specificity are not fully understood. Cellular studies of +TIP activity are complicated by the fact …

Capillary Electrophoresis Of Pteridines In Urine And Plants And Quantification Of Pharmaceutical And Personal Care Products In Missouri Waste Water, Stephen E. Gibbons

Doctoral Dissertations

"Capillary electrophoresis (CE) is a powerful technique that separates molecules based on their respective charge and hydrodynamic size. The major advantages of CE are high separation efficiency, small sample volume requirements, simple to no sample preparation and often organic solvents are not required for the separation.

The work presented in this dissertation utilized capillary electrophoresis for the analysis two different classes of compounds in different matrices. The first project investigated pteridines in urine and plants. The second project investigated pharmaceutical and personal care products (PPCP's) in Missouri waste water.

Female Humpback Whale (Megaptera Novaeangliae) Reproductive Class And Male-Female Interactions During The Breeding Season, Meagan E. Jones

Antioch University Dissertations & Theses

This study examined whether female reproductive class (i.e., presence or absence of a calf) in humpback whales (Megaptera novaeangliae) affects female behavior and male-female interactions on the Hawaiian breeding grounds. From 2003-2008, 295 female-calf groups (with or without a male escort) and 256 female no-calf groups (with a male) were observed. Forty-one female no-calf groups were confirmed male-female pairs by genetic sexing or photo-identification. Focal follows of 36 male-female pairs and 50 female-calf groups (29 escorted and 21 unescorted female-calf groups) were analyzed for time budget and movement estimates. Relative fluke size (fluke photogrammetry, n=30) and sighting histories …

The Transition Zone: Impact Of Riverbanks On Emergent Dragonfly Nymphs. Implications For Riverbank Restoration And Management, Kirsten Hope Martin

Antioch University Dissertations & Theses

The use of riprap in the restoration and stabilization of riverine landscapes is an issue of concern for many ecologists. While current methods of bank stabilization, especially those involving the placement of rocks (riprap) along the waterline, are effective in controlling erosion their presence changes habitat components (slope, substrate composition, near-shore river velocity) at the river-land interface. The additional impacts of river current, water temperature, soil composition, slope, and water level fluctuation, may further imperil emerging nymphs. The purpose of this research is to document the effects of riprap, location (upriver or downriver of hydroelectric intake/outtake facilities), water level fluctuation, …

Study Of The Microbial Diversity And Antimicrobial Properties Of Irish Edible Brown Seaweeds, Shilpi Gupta, Gaurav Rajauria, Nissreen Abu-Ghannam

Articles

Brown Irish edible seaweeds, Himanthalia elongata, Laminaria sachharina and Laminaria digitata, were evaluated for the microbiota in raw and heat processed form. Raw seaweeds showed complete absence of aerobic mesophiles, halophiles, yeasts and molds. However, heating at 85 C for 15 min resulted in spore germination. Bacterial counts as high as 107 were observed for aerobic mesophiles and halophiles. Heating above 95 C for 15 min resulted in complete inactivation of surface microflora. Bacteria belonging to Bacillaceae, Paenibacillaceae, Moraxellaceae and Enterobacteriaceae family were identified by 16S rRNA sequencing. In vitro antimicrobial activity of the methanolic extracts of the seaweed on …

Pk/Pd Modelling Of Comb-Shaped Pegylated Salmon Calcitonin Conjugates Of Differing Molecular Weights, Sinead Ryan, Jesus Maria Frias, David H. Haddleton, David J. Brayden

Articles

Salmon calcitonin (sCT) was conjugated via cysteine-1 to novel combed-shaped end-functionalised poly(PEG) methyl ether methacrylate) (sCT-P) comb-shaped polymers, to yield conjugates of total molecular weights (MW) inclusive of sCT: 6.5, 9.5, 23 and 40 kDa. The conjugates were characterised by HPLC and their in vitro and in vivo bioactivity was measured by cAMP assay on human T47D cells and following intravenous (i.v.) injection to rats, respectively. Stability against endopeptidases, rat serum and liver homogenates was assessed. There were linear and exponential relationships between conjugate MW with potency and efficacy respectively, however the largest MW conjugate still retained 70% of E …

A Needs Assessment For Continuing Education Of Federal Wildlife Damage Management Professionals, Jessica L. Tegt, Phillip D. Jones, Ben C. West

Human–Wildlife Interactions

The complexity of wildlife damage management requires professionals to continually acquire new knowledge and skills that can be obtained through continuing education. Current literature suggests that wildlife damage management personnel are not receiving adequate training either as new professionals entering the fi eld or through continuing training as existing professionals. To better understand the continuing education needs of wildlife damage managers, we conducted a nationwide, on-line needs assessment survey for supervisory personnel of the U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services program (hereafter, WS). The goal of our survey was to identify gaps in continuing …

Untreated And Enzyme-Modified Bovine Whey Products Reduce Association Of Salmonella Typhimurium, Escherichia Coli O157:H7 And Cronobacter Malonaticus (Formerly Enterobacter Sakazakii) To Caco-2 Cells, Rachel Halpin, D.B. Brady, E.D. O’Riordan, M. O’Sullivan

Articles

Adhesion of a micro-organism to a cell surface is often considered to be the first step in pathogenesis. Inhibiting this process may have therapeutic effects in vivo. This study investigates the inhibitory effects of various bovine whey products on the association of Salm. Typhimurium, E. coli O157:H7 and C. malonaticus (formerly Enterobacter sakazakii) to the human CaCo-2 cell line. Invasion of CaCo-2 cells by Salm. Typhimurium and C. malonaticus was also examined.

Magnetic Resonance Imaging And Surface-Based Analysis Techniques To Quantify Growth Of The Developing Brain, Andrew Knutsen

All Theses and Dissertations (ETDs)

Human brains, and those of most higher mammals, are gyrencephalic: folded) to accommodate a large cortical surface within the limited volume of the skull. Abnormal folding of the cerebral cortex in humans is associated with a number of neurological dysfunctions and diseases such as schizophrenia and Williams syndrome. To understand the mechanism of gyrification, and to illuminate the underlying causes of abnormal folding, objective, quantitative methods to characterize normal and abnormal development must be developed. The ferret is an excellent model in which to study the development of convolutions in the brain because folding occurs post-natally over a period of …

Trademark Remedies And Online Intermediaries, Stacey Dogan

Faculty Scholarship

For several years now, courts and commentators have tussled over the question of whether online intermediaries can face liability under trademark law. Because both case law and commentary have largely focused on the threshold question of "trademark use, " we know little about what specific behavior will subject intermediaries to liability and what remedies might follow. This Essay takes some preliminary steps toward addressing those questions.

A Phonetic, Phonological, And Morphosyntactic Analysis Of The Mara Language, Michelle Arden

Master's Theses

This thesis presents a linguistic analysis of the Mara language, a Tibeto-Burman language spoken in northwest Myanmar and in neighboring districts of India. Data has been gathered through interviews with a native speaker. The analysis includes a full phonetic segment inventory of the dialect and a phonological analysis of contrastive sounds and contextual variants. Sound files embedded in the document illustrate the phonetic system. Mara's distinctive phonetic features include the loss of word-final consonants, a set of voiceless sonorants, pre- and post- aspirated nasals, and lowered and unlowered vowel pairs. The morphosyntax of Mara pronominal words demonstrates a split-ergative case …

Interannual Differences In The Estuarine Ghost Shrimp, Neotrypaea Californiensis, Michael Buncic

Master's Theses

The dispersal of invertebrate marine larvae can be expected to be wide ranging and show little population structure. Neotrypaea californiensis, the burrowing ghost shrimp, is found throughout the waters and coastal estuaries of the northwestern United States. Three hundred and four larval samples were used to study population diversity and structural difference occurring over the course of spawning periods from June to September in successive years (2005 and 2006). Data and genetic analysis from nucleotide sequencing of a section of the mitochondrial Cytochrome C oxidase subunit I (COI) gene suggest that ocean-borne larvae off the coast of Oregon and Washington …

The time period surveyed in this thesis is from 1935 to 2000. The purpose was to establish any changes to reporting agricultural news over the years. A social history of agricultural journalism in the San Jose Mercury News over a 65-year period provided insight into how the farming industry was …

Western Pond Turtle Summer Habitat Use In A Coastal Watershed, Jae Abel

Master's Theses

Western pond turtle (Actinemys marmorata) habitat use was studied in a coastal pond, lagoon, and stream system during the summer of 1995 and 1996 at Waddell Creek, Santa Cruz County, California. Location and habitat association data were recorded for locations and sightings of radio-tagged and un-tagged turtles during the normal active season. Summary comparison of habitat associations and habitat availability provided inference of habitat preference at several habitat scales. For most of the active season the turtles were in relatively sunny aquatic habitat, in deeper, slower velocity water. In addition, the turtles were most commonly associated with exposed …

Flow Cytometry Of Alexandrium Catenella From Elkhorn Slough, California., Phillip Roland Hawkins

Master's Theses

This study describes the use of flow cytometry for the enumeration of the toxic marine dinoflagellate Alexandrium catenella in both estuarine samples from Elkhorn Slough, California and from sea water samples from inner Monterey Bay. Samples were subjected to a density-barrier sample enrichment technique employing percoll to separate debris from phytoplankton prior to sample fixation, labeling and analysis. Clarified, enriched preparations of phytoplankton were subjected to whole cell Fluorescent In Situ Hybridization (FISH) using a ribosomal DNA (rDNA) probe specific for the North American ribotype (NA1) of the dinoflagellate genus Alexandrium and analysis by flow cytometry. Flow cytometry was validated …

Review Of Law At The Vanishing Point By Aaron Fichtelberg, Robert D. Sloane

Faculty Scholarship

This is a largely critical review of Professor Aaron Fichtelberg’s philosophical analysis of international law. The centerpiece of the book’s affirmative agenda, a “non-reductionist” definition of international law that purports to elide various forms of international law skepticism, strikes the reviewer as circular, misguided in general, and, in its application to substantive international legal issues, difficult to distinguish from a rote form of legal positivism. Law at the Vanishing Point’s avowed empirical methodology and critical agenda, while largely unobjectionable, offer little that has not been said before, often with equal if not greater force. I commend the author’s effort to …

From The Classroom To The Courtroom: Intelligent Design And The Constitution, Jay D. Wexler

Faculty Scholarship

Although the Supreme Court of the United States has never developed a single clear test for determining what kinds of state action violate the Establishment Clause of the First Amendment, schools that attempt to teach or introduce intelligent design as a purportedly scientific alternative to evolution likely fall afoul of the First Amendment's commands. Under the Court's most relevant precedent, Edwards v. Aguillard, teaching intelligent design violates the Establishment Clause because, among other things, there is an enormous disconnect between the purpose of teaching intelligent design and its effect. Moreover, public school teachers do not possess any First Amendment right …

Balancing Of Markets, Litigation And Regulation, Keith N. Hylton, Larry E. Ribstein, Paul H. Rubin, Todd J. Zywicki

Faculty Scholarship

In addition to judicial education programs that the Law and Economics Center conducts, we also have a division that focuses on public policy research, known as the Searle Civil Justice Institute. In November, we held a public policy roundtable where we commissioned a variety of research and brought together a group of experts, both academic and practitioner experts, to discuss the issue of balancing the appropriate roles of markets, litigation, and regulation. And the notion there is that each one - markets, litigation, and regulation - can and probably should play a role in addressing various consumer harms.

International Law And African Judiciaries: The Example Of South Africa, Erika George

Faculty Scholarship

In recent years, commentators have questioned the extent to which African courts would rely upon foreign law or resort to rules of international law in their domestic decision making. I Comparatively, the African continent offers an interesting and important point of departure for exploring the influence of international law on domestic legal systems. While Africa boasts a number of new constitutional democracies, Africa is also home to a number of countries that remain burdened by colonial legacies and conflict.

It would not be unreasonable to expect international and foreign law to meet with considerable resistance or to be rejected as …

Poxvirus Complement Control Proteins Are Expressed On The Cell Surface Through An Intermolecular Disulfide Bridge With The Viral A56 Protein, Brian Dehaven

Biology Faculty Scholarship

The vaccinia virus (VACV) complement control protein (VCP) is an immunomodulatory protein that is both secreted from and expressed on the surface of infected cells. Surface expression of VCP occurs though an interaction with the viral transmembrane protein A56 and is dependent on a free N-terminal cysteine of VCP. Although A56 and VCP have been shown to interact in infected cells, the mechanism remains unclear. To investigate if A56 is sufficient for surface expression, we transiently expressed VCP and A56 in eukaryotic cell lines and found that they interact on the cell surface in the absence of other viral proteins. …

Supremacy Clause Textualism, Henry Paul Monaghan

Faculty Scholarship

Whatever its status in the statutory interpretation "wars," originalism-driven textualism has assumed an increasingly prominent role in constitutional interpretation, at least within the academy. The focus of this Article is on one such form, namely, "Supremacy Clause textualism", that is, recent textualist claims about the implications of the Supremacy Clause of Article VI. This Article addresses two such claims.

First, in important articles, Professor Bradford Clark argues that the clause is "at the epicenter of [our] constitutional structure" and it "recognizes only the 'Constitution,' 'Laws,' and 'Treaties' of the United States as 'the supreme Law of the Land."' Displacement of …
