Effects Of A Severe Cold Event On The Subtropical, Estuarine-Dependent Common Snook, Centropomus Undecimalis, Aaron J. Adams, Jessica E. Hill, Benjamin N. Kurth, Andrew B. Barbour

Gulf and Caribbean Research

The effects of infrequent disturbance events on marine fishes are often difficult to determine, due largely to lack of sufficient pre- and post-disturbance event data. In January 2010, subtropical southwestern Florida (USA) experienced extreme cold for 13 days, which caused extensive mortality of many fish species. The effect of this severe cold event on common snook (Centropomus undecimalis), an economically important gamefish, was assessed using three years (2007-2009) of pre-event and one year (2010) of post-event data from a tag-recapture program conducted over 28 km of Gulf of Mexico barrier islands of Florida. All metrics pointed to a …

Early Growth Of Three Kingfish (Menticirrhus) Species Found In Coastal Waters Of The Northern Gulf Of Mexico, E. John Anderson, Bruce H. Comyns, Harriet Perry, Chet F. Rakocinski

Gulf and Caribbean Research

Southern kingfish (Menticirrhus americanus), gulf kingfish (M. littoralis), and northern kingfish (M. saxatilis) are members of the drum family (Sciaenidae) that are widespread in coastal habitats of the western Atlantic, including in the Gulf of Mexico (GOM). Despite their economic and ecological importance, little is known about growth of young kingfish. Young kingfish were collected from four different Mississippi shoreline habitats in 2005 and 2006; two associated with barrier islands and two along the mainland. Barrier island habitats included surf zones on the south shore and grass beds on the north shore. Mainland habitats …

Flexible Feeding Strategies Of Juvenile Gray Triggerfish (Balistes Capriscus) And Planehead Filefish (Stephanolepis Hispidus) Within Sargassum Habitat, Sarah E. Ballard, Chet F. Rakocinski

Gulf and Caribbean Research

Sargassum-associated juvenile gray triggerfish and planehead filefish exhibited flexible feeding strategies in terms of their use of epifauna or pelagic zooplankton. Four diet samples represented instances of co-occurrence and segregated occurrence. Co-occurring gray triggerfish had the most specialized diets consisting mainly of pelagic copepods and hyperiid amphipods. Conversely, segregated triggerfish as well as both co-occurring and segregated filefish had broader diets mainly consisting of Sargassum epifauna, such as bryozoans, portunid crabs, and hippolytid shrimp. Still, co-occurring planehead filefish also consumed somewhat more zooplankton than segregated planehead filefish. Ontogenetic diet transitions were not as distinct for gray triggerfish as for …

A New Baseline For Diadema Antillarum, Echinometra Viridis, E. Lucunter, And Eucidaris Tribuloides Populations Within The Cayos Cochinos Mpa, Honduras, Paul A.X. Bologna, Lucy Webb-Wilson, Patrick Connelly, James E. Saunders

Gulf and Caribbean Research

We investigated the density of 4 urchin species from 5 shallow reefs in the Cayos Cochinos Marine Protected Area in Honduras. Individual species density varied among reefs with total urchin density ranging from 3.2–7.9 individuals/m². Echinometra viridis (Agassiz, 1863) was the numerically dominant species (2.29/m²) followed by E. lucunter (Linnaeus, 1758) (1.76/m²) with Eucidaris tribuloides (Lamarck 1816) representing the fewest individuals (0.42/m²). Our results indicated that density of Diadema antillarum (Philippi, 1845) differed significantly among reefs (0.4-1.3/m², mean = 0.63/m²), but are three times greater than data collected …

Using The Fishes Of Texas Project Databases And Recent Collections To Detect Range Expansions By Four Fish Species On The Lower Coastal Plain Of Texas, F. Douglas Martin, Adam E. Cohen, Dean A. Hendrickson

Gulf and Caribbean Research

The Fishes of Texas project online database is a large, freely available quality controlled fish occurrence database of museum vouchered specimens. We used data from it, the same project’s separate database of occurrences extracted from published literature and our own recent survey data to examine range stability for four fish species inhabiting the Texas Lower Coastal Plain: Fundulus chrysotus, Fundulus jenkinsi, Heterandria formosa and Poecilia formosa. A weakness of our data is that they consist of presences only and species absences can only rarely be inferred. To help adjust for this we used common widespread species as …

More Than A One-Trick Pony: Exploring The Contours Of A Multi-Sector Covener, Madeleine W. Mcnamara, John C. Morris

School of Public Service Faculty Publications

Today's managers must find ways to identify and sustain productive relationships within multi-sector collaborative arrangements. This paper explores empirically the activities of a convener based on tasks identified by Agranoff and McGuire (2001) and applies this framework to the case of Virginia's Coastal Zone Management Program (VCZMP). We find that the convener displays characteristics described by Agranoff and McGuire, as well as characteristics of traditional hierarchical managers. This research suggests that both sets of skills are necessary for effective multi-sector collaborative governance.

Protein Structure Networks, Lesley H. Greene

Chemistry & Biochemistry Faculty Publications

The application of the field of network science to the scientific disciplines of structural biology and biochemistry, have yielded important new insights into the nature and determinants of protein structures, function, dynamics and the folding process. Advancements in further understanding protein relationships through network science have also reshaped the way we view the connectivity of proteins in the protein universe. The canonical hierarchical classification can now be visualized for example, as a protein fold continuum. This review will survey several key advances in the expanding area of research being conducted to study protein structures and folding using network approaches.

Genetic Diversity Of The Caribbean Spiny Lobster Virus, Panulirus Argus Virus 1 (Pav1), And The Discovery Of Pav1 In Lobster Postlarvae, Jessica Moss, Mark J. Butler Iv, Donald C. Behringer Jr., Jeffrey D. Shields

Biological Sciences Faculty Publications

Panulirus argus virus 1 (PaV1) is an unclassified, pathogenic virus first discovered in Caribbean spiny lobsters Panulirus argus from the Florida Keys, USA, and has since been confirmed in lobsters in other parts of the Caribbean. Several studies have examined the prevalence, pathogenicity, and population dynamics of the pathogen in the lobster host, but little is known about the genetic diversity of the virus. We analyzed a fragment of viral DNA from lobsters collected in the Florida Keys, which provided the first insight into the genetic diversity of PaV1. The variation in viral sequences, both within and between individual lobsters, …

Effects Of Host Stored Resources On Bark Beetle-Fungal-Conifer Interactions, Eleanor Carol Lahr

Graduate Student Theses, Dissertations, & Professional Papers

Bark beetles and their associated fungi are among the greatest natural threats to conifers worldwide, but the degree to which host stored resources influence tree-beetle-fungal interactions has not been investigated. In western North America, the range of the mountain pine beetle (Dendroctonus ponderosae) has expanded from lower elevation Pinus contorta (lodgepole pine) forests into high elevation Pinus albicaulis (whitebark pine), a presumed superior host. I investigated whether stored resources in tree sapwood change after D. ponderosae attack, and whether this change relates to fungal colonization and beetle performance. I also studied how phloem and sapwood resources vary with elevation and …

Examination Of Scavenging Associated With Wolves, Jamie Bankaitis

Graduate Student Theses, Dissertations, & Professional Papers

Forensic anthropologists often confront external influences on a body, whether they are human, animal, or environmental. One of the major and most common confounding factors for forensic anthropologists is animal scavenging and the damage this inflicts on the skeleton. The types of scavengers present vary from region to region, and in the Northwest, large carnivores such as bears, mountain lions, and canids are abundant. These types of carnivores can not only inflict incredible trauma to a skeleton, they can also disperse the remains over very large areas, making it difficult for forensic teams to recover all of the skeletal elements …

Inference For High-Dimensional Doubly Multivariate Data Under General Conditions, John Zachary Hossler

Graduate Student Theses, Dissertations, & Professional Papers

With technological, research, and theoretical advancements, the amount of data being generated for analysis is growing rapidly. In many cases, the number of subjects may be small, but the number of measurements taken on each subject may be very large. Consider, for example, two groups of patients. The subjects in one group are diseased and the other subjects are not. Over 9,000 relative fluorescent unit (RFU) signals, measures of the presence and abundance of proteins, are collected in a microarray or protoarray from each subject. Typically these kind of data show marked skewness (departure from normality) which invalidates standard multivariate …

Restoring The "Shining Waters": Milltown, Montana And The History Of Superfund Implementation, David James Brooks

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation is a case study of a dam removal and river restoration within the nation's largest Superfund site. In 1981, the U.S. Environmental Protection Agency included Milltown Reservoir on its first list of Superfund sites. Superfund law capped two decades of the federal government's most aggressive environmental legislation. While tracking the national story of Superfund law, my story provides a local view of how individuals, organizations, and agencies shaped the Superfund process. After the EPA designated Milltown a national Superfund site, the environment itself, persistent work within the channels of public policy, and federally-mediated compromise helped restore some shine …

Sarah Palin, Conservative Feminism, And The Politics Of Family, Jasmine Rose Zink

Graduate Student Theses, Dissertations, & Professional Papers

Female politicians are heavily constrained by discourses that prescribe masculine values as natural, yet at times they draw on societal expectations of femininity that allow them to utilize such discourses to their advantage. Motherhood, a feminine yet powerful role, provides such an opportunity. Capitalizing on this acceptable avenue of female power, women have strategically relied on maternal appeals since they first entered public life, often to challenge patriarchal social structures. Utilizing Lakoff‘s (2002) concept of the nation-as-family metaphor and informed by the pervasive myth of the traditional family, this analysis explores the consequences of Sarah Palin‘s use of maternal appeals …

Spectral Identification Of Wild Rice (Zizania Palustris L.) Using Indigenous Knowledge And Landsat Multispectral Data, Michael Wassegijig Price

Graduate Student Theses, Dissertations, & Professional Papers

Landsat-7 ETM+ (SLC-off) multispectral satellite imagery was tested to identify and delineate natural stands of wild rice (Zizania palustris L.) from other aquatic vegetation growing on area lakes of the Leech Lake Native American reservation in northern Minnesota. Leech Lake is located within the Mississippi River Headwaters drainage ecosystem and contains some of the largest natural stands of wild rice in the country. Local indigenous knowledge; in this case, the knowledge of Ojibwe tribal elders who have traditionally harvested wild rice by canoe for centuries, was utilized to build training data polygons for a supervised classification. By testing several supervised …

Assessing The Role Of Shame And Honor During The Alta Conflict, Michael T. Bremmer

Graduate Student Theses, Dissertations, & Professional Papers

For nearly a century the Sami peoples of Norway were subject to colonial policies of assimilation and integration. According to historians of the Sami, colonial processes stigmatized Sami individuals and the Sami culture, producing feelings of shame. The concept of shame, for both individuals and groups, centers on experiencing fear, pain, and/or uneasiness, and requires a judging audience. Honor is about individuals transcending self-interest and the need for individuals and groups to acquire self-esteem for that purpose; it also requires a judging audience. Concepts of shame and honor played an important role during the Alta conflict; a watershed moment in …

Anomalous Wave Dispersion In The Cyclohexanedione-Bromate Chemical Oscillator, Ryan Boger

Graduate Student Theses, Dissertations, & Professional Papers

A modified six-variable Oregonator model presented here successfully reproduces a significant portion of the behavior observed in the Ferroin-catalyzed cyclohexanedione variant of the Belousov-Zhabotinsky (CHD-BZ) reaction. The phenomena of anomalous velocity dispersion (in which following waves may catch up to, rather than fall behind an initial excitation wave), wave-stacking, and backfiring have been successfully reproduced numerically as resulting from non-monotonic [Br-] decay to the steady state in the wake of an excitation pulse. The non-monotonic decay is seen as a "dip" in [Br-] following the passage of a chemical wave. This dip in [Br-] decay curve allows a following wave …

Reclaiming Global Environmental Leadership: Why The United States Should Ratify Ten Pending Environmental Treaties, Mary Jane Angelo, Rebecca M. Bratspies, David Hunter, John H. Knox, Noah Sachs, Sandra B. Zellmer

Working Papers

For more than a century, the United States has taken the lead in organizing international responses to international environmental problems. In the last two decades, however, U.S. environmental leadership has faltered. The best-known example is the lack of an effective response to climate change, underscored by the U.S. decision not to join the Kyoto Protocol. But that is not the only shortfall. The United States has also failed to join a large and growing number of treaties directed at other environmental threats, including marine pollution, the loss of biological diversity, persistent organic pollutants, and trade in toxic substances. This white …

Rights Of Concrete Others: Ethics Of Concrete Others, Social Individuality, And Social Multiculturalism, Hochul Kwak

CGU Theses & Dissertations

A globalizing world is replete with the vulnerable, who are experiencing economic poverty, medical maltreatment, political persecution, and/or cultural misrecognition. The vulnerable are under systematic oppression and domination. Although the wealth of humankind increases continuously, many are excluded from any benefit of this increased wealth. While human beings have achieved significant progress in medical technology, uncountable numbers of people are exposed to a shortage of appropriate medical care. Despite continued expansion of democracy around the globe, the powerless majority and minorities are experiencing ignorance of their differences, culturally and/or politically. This dissertation searches for a viable human rights scheme that …

Early Adolescent Non-Suicidal Self-Injury And Sensory Preference Differences: An Exploratory Study, Jacquelyn Shea Christensen

CGU Theses & Dissertations

BACKGROUND: Non-suicidal self-injury (NSSI) occurs in 13% to 20% of adolescents, and is often indicative of deeper internal or social problems. A close review of current explanatory models of NSSI suggested that underlying individual sensory preferences may contribute substantial explanations for the self-regulatory functions of NSSI, as well as have implications for treatment approaches. In the context of integrating sensory processing models with prominent functional NSSI models, this dissertation research compared sensory preferences in youth who engaged in NSSI to sensory preferences of youth who did not engage in NSSI.

OBJECTIVE: NSSI-engaging youth were hypothesized to have lower threshold sensory …

Investigation Into The Specificity Of Angiotensin Ii-Induced Behavioral Desensitization, Peter J. Vento, Kevin P. Myers, Derek Daniels

Faculty Journal Articles

Angiotensin II (AngII) plays a key role in maintaining body fluid homeostasis. The physiological and behavioral effects of central AngII include increased blood pressure and fluid intake. In vitro experiments demonstrate that repeated exposure to AngII reduces the efficacy of subsequent AngII, and behavioral studies indicate that prior icv AngII administration reduces the dipsogenic response to AngII administered later. Specifically, rats given a treatment regimen of three icv injections of a large dose of AngII, each separated by 20 min, drink less water in response to a test injection of AngII than do vehicle-treated controls given the same test injection. …

Much like the Quality Revolution did in the 1980's, corporate sustainability has the potential to drive significant changes in the processes and structure of various organizations in the coming decade. With a rapidly growing global population and an ever increasing global demand for resources (Population-Resource-Center, 2012). Sustainability has emerged as one of the primary challenges that organizations will have to deal with in the 21st century. An increasing realization among business executives that profitability by itself is not enough as a measure of success is also driving the increased adoption of sustainable practices in the corporate world (Lowitt and Grimsley, …

Protandric Simultaneous Hermaphroditism In Parhippolyte Misticia (Clark, 1989) (Caridea: Hippolytidae): Implications For The Evolution Of Mixed Sexual Systems In Shrimp, Hitoshi Onaga, G. Curt Fiedler, J. Antonio Baeza

Biological Sciences Faculty Publications

The sexual system of the shrimp Parhippolyte misticia (Clark, 1989), inhabiting the rocky subtidal at Okinawa, Japan and Kimbe Bay, Papua New Guinea, was examined. Dissections suggested that the population consisted of male phase (MP) and functional simultaneous euhermaphrodite (EH) individuals. MPs have cincinulli and appendices masculinae on the first and second pair of pleopods, respectively, gonopores located at the coxae of the third pair of walking legs, and ovotestes with a well-developed male portion containing sperm, but an undeveloped female portion. EHs lacked appendices masculinae and cincinulli. However, they have male gonopores and ovotestes with well-developed ovaries containing mature …

Brooding, Provisioning, And Compensatory Care In The Cooperatively Breeding Acorn Woodpecker, Walter D. Koenig, Eric L. Walters

Biological Sciences Faculty Publications

We analyzed reproductive investment in parental care (brooding and the provisioning of nestlings) in the acorn woodpecker (Melanerpes formicivorus), a cooperatively breeding species in which both polygynandry and helping-at-the-nest are common. As predicted based on the strategies pursued by birds of different sex and status, breeders generally invested more in parental care than helpers, and breeder females invested more than breeder males. Contrary to expectations, however, the degree to which individuals reduced their effort with increasing group size (i.e., patterns of load lightening or compensatory care) did not match overall investment. Instead, as group size increased, there was …
