Feeding In The Dark: Lateral-Line-Mediated Prey Detection In The Peacock Cichlid Aulonocara Stuartgranti, Margot A. B. Schwalbe, Daniel K. Bassett, Jacqueline F. Webb

Biological Sciences Faculty Publications

The cranial lateral line canal system of teleost fishes is morphologically diverse and is characterized by four patterns. One of these, widened lateral line canals, has evolved convergently in a wide range of teleosts, including the Lake Malawi peacock cichlids (Aulonocara), and has been attributed to its role in prey detection. The ability to study Aulonocara in the laboratory provides an opportunity to test the hypothesis that their reported ability to feed on invertebrate prey living in sandy substrates in their natural habitat is the result of lateral-line-mediated prey detection. The goal of this study was to determine …

Allocation Of Endogenous And Dietary Protein In The Reconstitution Of The Gastrointestinal Tract In Migratory Blackcaps At Stopover Sites, Agusti Muñoz-Garcia, Sarah Aamidor, Marshall D. Mccue, Scott R. Mcwilliams, Berry Pinshow

Natural Resources Science Faculty Publications

During migratory flight, the mass of the gastrointestinal tract (GIT) and its associated organs in small birds decreases in size by as much as 40%, compared with the preflight condition because of the catabolism of protein. At stopover sites, birds need 2–3 days to rebuild their GIT so that they can restore body mass and fat reserves to continue migration. The source of protein used to rebuild the GIT may be exogenous (from food ingested) or endogenous (reallocated from other organs) or both. Because the relative contribution of these sources to rebuild the GIT of migratory birds is not yet …

Taste Neophobia And C-Fos Expression In The Rat Brain, Jian-You Lin, Christopher T. Roman, Joe Arthurs, Steve Reilly

Scholarship and Professional Work – COPHS

Taste neophobia refers to a reduction in consumption of a novel taste relative to when it is familiar. To gain more understanding of the neural basis of this phenomenon, the current study examined whether a novel taste (0.5% saccharin) supports a different pattern of c-Fos expression than the same taste when it is familiar. Results revealed that the taste of the novel saccharin solution evoked more Fos immunoreactivity than the familiar taste of saccharin in the basolateral region of the amygdala, central nucleus of the amygdala, gustatory portion of the thalamus, and the gustatory insular cortex. No such differential expression …

Judicial Opinions And Appellate Advocacy In Federal Courts - One Judge's Views, Richard A. Posner

Duquesne Law Review

I have been a federal court of appeals judge for thirty years, and naturally over this long span of time I have formed judgments about how federal court of appeals judges should go about deciding cases, what their judicial opinions should be like (which raises the issue of how judges should use staff, consisting mainly of law clerks), and how lawyers should brief and argue cases in these courts. My purpose in this article is to distill my beliefs concerning opinions and advocacy into practical advice for federal court of appeals judges, their law clerks, and the lawyers who practice …

The Future Of Agriculture And Society In Iowa: Four Scenarios, Meghann E. Jarchow, G. L. Drake Larsen, Robert Costanza, Gretchen Zdorkowski, Stefans R.

Institute for Sustainable Solutions Publications and Presentations

Iowa is a leader in crop and livestock production, but its high productivity has had concomitant negative environmental and societal impacts and large requirements for fossil-fuel-derived inputs. Maintaining agricultural productivity, economic prosperity and environmental integrity will become ever more challenging as the global demand for agricultural products increases and the resources needed become increasingly limited. Here we present four scenarios for Iowa in 2100, based on combinations of differing goals for the economy and differing energy availability. In scenarios focused on high material throughput, environmental degradation and social unrest will increase. In scenarios with a focus on human and environmental …

Scaffolding For Cognitive Overload Using Pre-Lecture E-Resources (Scope) For First Year Chemistry Undergraduates, Claire M. Mcdonnell, Christine O'Connor, Sarah Rawe

Teaching Fellowships

The aims of this project were: to develop additional online pre-lecture resources for first year chemistry undergraduates at level 7 and 8 to complement those prepared in the 2010/2911 academic year for level 8 students by Dr. Michael Seery as part of his teaching fellowship, and to evaluate the effect of implementing the resources with this year by analysing quantitative (test and exam results) and qualitative (pre-and post-implementation surveys and focus group interviews) data. Ten pre-lecture activities on organic chemistry were prepared and used with 87 level 8 students in Semester 2 and ten more on general chemistry topics have …

Spatial Heterogeneity Across Five Rangelands Managed With Pyric-Herbivory, Devan Allen Mcgranahan, David M. Engle, Samuel D. Fuhlendorf, Stephen L. Winter, James R. Miller, Diane M. Debinski

School of Natural Resources: Faculty Publications

1. Many rangelands evolved under an interactive disturbance regime in which grazers respond to the spatial pattern of fire and create a patchy, heterogeneous landscape. Spatially heterogeneous fire and grazing create heterogeneity in vegetation structure at the landscape level (patch contrast) and increase rangeland biodiversity. We analyzed five experiments comparing spatially heterogeneous fire treatments to spatially homogeneous fire treatments on grazed rangeland along a precipitation gradient in the North American Great Plains.

2. We predicted that, across the precipitation gradient, management for heterogeneity increases both patch contrast and variance in the composition of plant functional groups. Furthermore, we predicted that …

The Rock Art Of The Blood Of The Ancestors Grotto (11sa557): The Archaeology Of Religious Theater, Lenville J. Stelle

Anthropology Faculty Scholarship

11SA557 is a pictographic rock art site in the Hill Section of southern Illinois. To date, 33 icons, both simple and complex, have been identified. The distinctive biophysical qualities of the site have compelled an interpretation that it was in some fundamental sense “female.” Ethnohistorical and ethnographic explorations inform a treatment of 11SA557 as a religious theater where female puberty ceremonies of the Dhegiha Sioux were performed. Exploitation likely dates to the Protohistoric period. Twenty-one elements of religious theater are explored archaeologically and ethnographically. The application of the heuristic model of religious theater afforded a measureable enhancement of the understanding …

Mozambique's "Land Grab": Exploring Approaches To Elite Policymaking And Neoliberal Reform, Hannah Wittmeyer

Political Science Student Work

Large-scale farmland acquisitions in Africa – widely known as “land grabbing” – have increased dramatically over the past few years. By the end of 2011, governments negotiating these leases transferred over 50 million hectares of fertile land to foreign investors. Alarmed by the implications of food and bio-fuel crops being grown and exported from food-insecure states, international media and activist organizations have used “neo-colonialism” as an epithet to describe the wave of investments – implying exploitation by foreign powers and corporate interests.

This contribution instead analyzes “land grabbing” from a competing perspective. I begin by asking why African states choose …

Co-Crystallization And Polymorphism Of Naturally Occurring Peptide Derivatives, Kevin Crowley

Bridges: A Journal of Student Research

Carnosine is a dipeptide compound that is found in many dietary supplements and food products. Carnosine has many functions in the body, such as alleviating oxidative stress on tissues by acting as an antioxidant compound. Carnosine, therefore, has important anti-aging properties. Carnosine is also capable of forming protective sequestration structures around heavy metal ions; this process of chelating metals ions in solutions is very beneficial for maintaining the well-being of cells in the body. Thus, carnosine could be useful in pharmaceutical products for creating anti-aging drugs that would reduce tissue stress and promote a healthy cellular environment. I attempted to …

Power And The Polis: A Study In Macintyrean State Theory, Benjamin Sehnert

Classics Student Work

Alasdair MacIntyre’s theory of the state is often viewed by critics as being unnecessarily hostile to modern political arrangements, particularly the modern state. However, many critics of MacIntyre do not argue on MacIntyre’s own terms, that is, they argue from distinctly modern positions. The first section of the thesis will be devoted to explaining why such criticisms of MacIntyrean state theory are bound to fail or at least be easily dismissed. I will discuss in particular MacIntyre’s theory of tradition-dependent rationality and how one must work to develop an idea within a tradition rather than attacking it from the outside. …

Nutrient Supply And Mercury Dynamics In Marine Ecosystems: A Conceptual Model, Charles T. Driscoll, Celia Y. Chen, Chad R. Hammerschmidt, Robert P. Mason, Cynthia C. Gilmour, Elsie M. Sunderland, Ben K. Greenfield, Kate L. Buckman, Carl H. Lamborg

Civil and Environmental Engineering - All Scholarship

There is increasing interest and concern over the impacts of mercury (Hg) inputs to marine ecosystems. One of the challenges in assessing these effects is that the cycling and trophic transfer of Hg are strongly linked to other contaminants and disturbances. In addition to Hg, a major problem facing coastal waters is the impacts of elevated nutrient, particularly nitrogen (N), inputs. Increases in nutrient loading alter coastal ecosystems in ways that should change the transport, transformations and fate of Hg, including increases in fixation of organic carbon and deposition to sediments, decreases in the redox status of sediments and changes …

The Three-Fold Significance Of The Blaming Emotions, Zac Cogley

Publication

Much of the philosophical work on moral responsibility assumes that we should understand people’s moral responsibility for the actions they take in terms of the appropriateness of the blaming emotions—resentment, anger, and indignation. However, current theorizing about the blaming emotions is often psychologically uninformed. Drawing on work in empirical psychology, I have recently argued that anger serves three functions in human psychology: appraisal, motivation, and communication. In this project, I propose to extend that analysis to the entire class of blaming emotions. I will show that theorizing about moral responsibility is myopic if it focuses on one of the functions …

Analytical Strategies For Drug Residues In Various Matrices In A Regulatory Laboratory., Geraldine Dowling

Dissertations

Abstract

Today, in modern farming practices veterinary drugs are given to food-producing animals. The generic term “veterinary drugs” covers a broad variety of classes of chemical compounds and the list of drugs is enormous and it is a significant analytical challenge in regulatory control to provide monitoring programmes. The major concerns in veterinary drug usage are the presence of harmful residues that may be introduced into the human food chain. The aim of this research is the development of analytical methods capable of screening and confirming increased numbers of these residues in target matrices by Gas Chromatography Tandem Mass Spectrometry …

Intermittent Bioirrigation And Oxygen Dynamics In Permeable Sediments: An Experimental And Modeling Study Of Three Tellinid Bivalves, Nils Volkenborn, Christof Meile, Lubos Polerecky, Conrad A. Pilditch, Alf Norkko, Joanna Norkko, Judi E. Hewitt, Simon F. Thrush, David S. Wethey, Sarah A. Woodin

Journal of Marine Research

To explore the dynamic nature of geochemical conditions in bioirrigated marine permeable sediments, we studied the hydraulic activity of three tellinacean bivalve molluscs (the Pacific species Macoma nasuta and Macomona liliana, and the northern Atlantic and Pacific species Macoma balthica). We combined porewater pressure sensing, time-lapse photography and oxygen imaging to quantify the durations and frequencies of tellinid irrigation activity and the associated oxygen dynamics in the sediment. Porewater pressure records of all tellinids were dominated by intermittent porewater pressurization, induced by periodic water injection into the sediment through their excurrent siphons, which resulted in intermittent oxygen supply …

The Norquest Family: A Porción Of Edinburg, University Of Texas--Pan American. Community Historical Archaeology Project With Schools Program (Chaps), Margaret E. Dorsey, Sandra Hernandez-Salinas, Maria Barrera, Roseann Bacha-Garza

Community Historical Archaeology Project with Schools (CHAPS) Publications

The Norquest family immigrated to their farm site in 1925 as part of a larger wave of Midwestern immigrants to the Lower Rio Grande Valley. At the turn of the twentieth century, the Valley also experienced an influx of Mexican migrants in search of opportunity and work. They joined their Mexican-American counterparts laboring as agricultural workers on the farms of Anglos and Texas-Mexicans. Some of these individuals found their way onto the Norquest farm site. This multidisciplinary report posits a nuanced way of looking at human-land interaction on a farmsite in South Texas, where racial and class conflict existed, but …
