Effects Of Nitrogen-Fixing Symbiotic Cyanobacteria On The Microbial Ecology Of The Coral, Montastraea Cavernosa, Jessica K. Jarett

Doctoral Dissertations

Corals form the physical structure of coral reefs, one of the most ecologically and economically important ecosystems in the world. The abundant and broadly distributed Caribbean coral Montastraea cavernosa forms a symbiosis with intracellular nitrogen-fixing cyanobacteria in some, but not all colonies, which make up approximately 30% of the population and display a characteristic orange fluorescence. Diverse and functionally important microbial communities of dinoflagellates, bacteria, Archaea, viruses, fungi, and other organisms are also associated with corals and together with the host compose what is termed the coral holobiont. Whether the cyanobacteria are mutualists, commensals, or parasites, and their effects on …

Flatfish Stock Enhancement: Examining Conditioning Strategies To Promote Success, Michelle Lynn Walsh

Doctoral Dissertations

Conditioning is the process of providing individuals reared for stock enhancement with some degree of "wild" experience prior to release. Flatfish trained for "wild" conditions may more easily and successfully transition to natural environments. This dissertation identifies strategies that optimize feeding-related performance of flatfish in the hatchery and subsequently post release in the wild.

The influence of live feed conditioning on feeding performance of juvenile winter flounder, Pseudopleuronectes americanus, was investigated. In the hatchery, fish reared on live feeds exhibited significantly higher survival (P < 0.0001) and growth (P < 0.01) than those reared on formulated feed. Once released into cages in the wild, amphipodreared fish had higher mean Stomach Contents Index and RNA/DNA of all feed types, including wild fish. Wild and worm-reared fish exhibited the most similar survival, baseline RNA/DNA values, overall stomach fullness, and diet composition profiles over time.

Pre-release, experimental cage conditioning was conducted for stocking Japanese flounder, Paralichthys olivaceus, in Wakasa Bay, Japan. …

Eating Quality And Variability In Carotenoid Content And Profiles In Winter Squash And Sweet Potato, Jennifer Bonina Noseworthy

Doctoral Dissertations

A comprehensive study at the New Hampshire Agricultural Experiment Station (NHAES) of 16 winter squash cultigens (Cucurbita spp.), including inbred lines and open pollinated and F1 hybrid cultivars from the University of New Hampshire breeding program, was undertaken to determine dry weight (%DW), soluble solids contents (%SSC) and carotenoid contents of mesocarp tissue, major attributes for determining acceptable eating quality and nutritional content. Data were recorded at harvest, either 40 or 60 days after pollination (DAP), and after 30 and 60 days of storage at 14 °C. Carotenoid contents were determined spectrophotometrically and using high performance liquid chromatography (HPLC).

Exposure To Silver Nanoparticles Inhibits Selenoprotein Synthesis And The Activity Of Thioredoxin Reductase, Milan Srivastava, Sanjay Singh, William T. Self

Faculty Bibliography 2010s

BACKGROUND: Silver nanoparticles (AgNPs) and silver (Ag)-based materials are increasingly being incorporated into consumer products, and although humans have been exposed to colloidal Ag in many forms for decades, this rise in the use of Ag materials has spurred interest into their toxicology. Recent reports have shown that exposure to AgNPs or Ag ions leads to oxidative stress, endoplasmic reticulum stress, and reduced cell proliferation. Previous studies have shown that Ag accumulates in tissues as silver sulfides (Ag2S) and silver selenide (Ag2Se). OBJECTIVES: In this study we investigated whether exposure of cells in culture to AgNPs or Ag ions at …

Lifting The Veil On Rigorous Rational Basis Scrutiny, Miranda Oshige Mcgowan

Marquette Law Review

In many different cases, the Supreme Court and lower courts have used a rigorous form of rational basis scrutiny very different from the ordinary, deferential rational basis scrutiny taught in constitutional law courses. When invoked, this more rigorous form of rational basis scrutiny has proven fatal to statutes and regulations. Many scholars and courts have described how courts apply it and have defended particular cases in which it has been used. No one, however, has explained just why and when courts will or ought to apply it. This gap is troublesome and pressing. Rigorous rational basis scrutiny is an important …

Life After Act 10?: Is There A Future For Collective Representation Of Wisconsin Public Employees?, Martin H. Malin

Marquette Law Review

In 2011, Wisconsin largely gutted the collective bargaining rights of most public employees in the state. Wisconsin Act 10 largely replaced collective employee voice with unilateral employer control over employees’ wages, hours, and terms and conditions of employment. This article addresses the future of collective employee representation in Wisconsin in the wake of Act 10. It urges employers to continue to engage with their employees through the employees’ unions, demonstrating why such an approach better provides for the public interest than unilateral employer control. It looks to examples from other jurisdictions and presents a range of alternatives for Wisconsin public …

The Animal Rights Debate And The Expansion Of Public Discourse: Is It Possible For The Law Protecting Animals To Simultaneously Fail And Succeed?, Peter Sankoff

Animal Law Review

This Article uses the theory of deliberative democracy, as developed by Jürgen Habermas and others, to suggest that public discourse is essential to encouraging democratic change in animal welfare law. The author examines the legal regimes of Canada and New Zealand to determine which country better facilitates a public dialogue about the treatment of animals. The Article concludes that, while Canada has a number of laws that ostensibly protect animals, New Zealand’s regime is much better at creating the public discourse required to meaningfully advance animal protection. The author does not suggest that New Zealand’s regime is perfect; rather, New …

On-Plant Movement And Feeding Of Western Bean Cutworm (Lepidoptera: Noctuidae) Early Instars On Corn, Silvana L. Vieira De Paula Moraes, Thomas E. Hunt, Robert J. Wright, Gary L. Hein, Erin E. Blankenship

Department of Entomology: Faculty Publications

Western bean cutworm, Striacosta albicosta (Smith), has undergone a recent eastward expansion from the western United States Corn Belt to Pennsylvania and parts of Canada. Little is known about its ecology and behavior, particularly during the early instars, on corn (Zea mays L.). There is a narrow treatment window for larvae, and early detection of the pest in the field is essential. An understanding of western bean cutworm larval feeding and early-instar dispersal is essential to understand larval survival and establishment in corn. Studies were conducted in 2009 through 2011 in Nebraska to determine the feeding and dispersal of …

Toxin-Antitoxic Loci Vapbc-1 And Vapxd Contribute To Survival And Virulence In Nontypeable Haemophilus Influenzae, Dabin Ren, Anna N. Walker, Dayle A. Daines

Biological Sciences Faculty Publications

Background: Nontypeable Haemophilus influenzae (NTHi) is a significant human pathogen responsible for respiratory tract infections and the most common cause of recurrent otitis media. Type II toxin-antitoxin (TA) systems are genetic elements that code for a stable protein toxin and a labile antitoxin that are thought to be involved in metabolic regulation of bacteria by enabling a switch to a dormant state under stress conditions. The contribution to infection persistence of the NTHi TA loci vapBC-1 and vapXD was examined in this study.

Results: Deletions in vapBC-1, vapXD and vapBC-1 vapXD significantly decreased the survival of NTHi co-cultured with …

First Stable Isotope Analysis Of Asiatic Wild Ass Tail Hair From The Mongolian Gobi, Micha Horacek, Petra Kaczensky, Merina Burnik Sturm

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Stable isotope analysis has become a powerful tool to study feeding ecology, water use or movement pattern in contemporary, historic and ancient species. Certain hair and teeth grow continuously, and when sampled longitudinally can provide temporally explicit information on dietary regime and movement pattern. In an initial trial, we analysed a tail sample of an Asiatic wild ass (Equus hemionus) from the Mongolian Gobi. We found seasonal variations in H, C, and N isotope patterns, likely being the result of temporal variations in available feeds, water supply and possibly physiological status. Thus stable isotope analysis shows promise to …

The Development Of Science Identity: An Evaluation Of Youth Development Programs At The Museum Of Science And Industry, Chicago, Sam Cole

Dissertations

The following dissertation presents findings from a year-long evaluation of informal scientific education programs at the Museum of Science and Industry in Chicago, Illinois. Science identity, rather than scientific knowledge, was the analytic lens through which the programs' effectiveness was assessed. A goal of the Museum generally, and the programs specifically, is to increase public identification with the field of science. Science identity was assessed using a novel survey instrument and three focus groups. Hierarchical linear models found a positive relationship between time enrolled in the Science Minors program and the development of science identity. These analyses also point to …

The Effects Of Smooth Muscle Cells On Engineered Microvasculatures In Fibrin Hydrogels, Areck A. Ucuzian

Dissertations

Capillaries are comprised of two cell types: the endothelial cells (ECs) which line the lumen of the capillary, and the supporting pericytes which are closely apposed to the abluminal surface of the capillary wall (sometimes called mural cells). These pericytes are phenotypic derivations of mesenchymal organ stromal cells (from smooth muscle cells and fibroblasts in blood vessels, for example), are recruited and incorporate into the neocapillaries, and are known to mediate reciprocal interactions with ECs during angiogenesis. The overall purpose of this project is to determine how smooth muscle cells (SMCs) affect angiogenesis during microvascular development in fibrin hydrogels using …
