Algal Genomes Reveal Evolutionary Mosaicism And The Fate Of Nucleomorphs, Bruce A. Curtis, Christopher E. Lane, Et Al

Biological Sciences Faculty Publications

Cryptophyte and chlorarachniophyte algae are transitional forms in the widespread secondary endosymbiotic acquisition of photosynthesis by engulfment of eukaryotic algae. Unlike most secondary plastid-bearing algae, miniaturized versions of the endosymbiont nuclei (nucleomorphs) persist in cryptophytes and chlorarachniophytes. To determine why, and to address other fundamental questions about eukaryote–eukaryote endosymbiosis, we sequenced the nuclear genomes of the cryptophyte Guillardia theta and the chlorarachniophyte Bigelowiella natans. Both genomes have >21,000 protein genes and are intron rich, and B. natans exhibits unprecedented alternative splicing for a single-celled organism. Phylogenomic analyses and subcellular targeting predictions reveal extensive genetic and biochemical mosaicism, with both …

Temperature Compensation Of Aerobic Capacity And Performance In The Antarctic Pteropod, Clione Antarctica, Compared With Its Northern Congener, C. Limacina, Agnieszka K. Dymowska, Thomas Manfredi, Joshua J. C. Rosenthal, Brad A. Seibel

Biological Sciences Faculty Publications

In ectotherms living in cold waters, locomotory performance is constrained by a slower generation of the ATP that is needed to fuel muscle contraction. Both polar and temperate pteropods of the genus Clione, however, are able to swim continuously by flapping their parapodia (wings) at comparable frequencies at their respective habitat temperatures. Therefore, we expected polar species to have increased aerobic capacities in their wing muscles when measured at common temperatures. We investigated muscle and mitochondrial ultrastructure of Clione antarctica from the Southern Ocean (−1.8°C) and populations of a sister species, Clione limacina, from the Arctic (−0.5 to …

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 …

Tissue-Specific Alterations Of Prl-1 And Prl-2 Expression In Cancer, Carmen M. Dumaual, George E. Sandusky, Han Weng Soo, Sean R. Werner, Pamela L. Crowell, Stephen K. Randall

Scholarship and Professional Work – COPHS

The PRL-1 and PRL-2 phosphatases have been implicated as oncogenic, however the involvement of these molecules in human neoplasms is not well understood. To increase understanding of the role PRL-1 and PRL-2 play in the neoplastic process, in situ hybridization was used to examine PRL-1 and PRL-2 mRNA expression in 285 normal, benign, and malignant human tissues of diverse origin. Immunohistochemical analysis was performed on a subset of these. PRL-1 and PRL-2 mRNA expression was also assessed in a small set of samples from a variety of diseases other than cancer. Where possible, associations with clinicopathological characteristics were evaluated. Alterations …

Public School Superintendent Philosophies And Their Tenure., John Garner

All-Inclusive List of Electronic Theses and Dissertations

Postmodernism is a philosophical description that encompasses philosophy, the arts, a period of history, and many other aspects of today's existence. This dissertation examines the extent to which Indiana public school superintendents use postmodern philosophy as opposed to modern philosophy to inform their practice. This was accomplished by examining eight leadership concepts through the application of questions with decisions related to either modernism or postmodernism. The study described by this dissertation used a quantitative research method assembling data and determining the correlation of operant philosophy by a superintendent with their tenure.

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 …

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 …

Kurz, David T. Price, Peter M. Lafleur, Rachhpal S. Jassal, Danilo Dragoni, Gil Bohrer, Christopher M. Gough, Shashi B. Verma, Andrew E. Suyker, J. William Munger

School of Natural Resources: Faculty Publications

Understanding feedbacks of ecosystem carbon sequestration to climate change is an urgent step in developing future ecosystem models. Using 187 site-years of flux data observed at 24 sites covering three plant functional types (i.e. evergreen forests (EF), deciduous forests (DF) and non-forest ecosystems (NF) (e.g., crop, grassland, wetland)) in North America, we present an analysis of both interannual and spatial relationships between annual net ecosystem production (NEP) and phenological indicators, including the flux-based carbon uptake period (CUP) and its transitions, degree-day-derived growing season length (GSL), and spring and autumn temperatures. Diverse responses were acquired between annul NEP and these indicators …

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 …

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. …

A Synthesis Of Rates And Controls On Elemental Mercury Evasion In The Great Lakes Basin, Joseph S. Denkenberger, Charles T. Driscoll, Brian A. Branfireun, Chris S. Eckley, Mark Cohen, Pranesh Selvendiran

Civil and Environmental Engineering - All Scholarship

Rates of surface-air elemental mercury (Hgo) fluxes in the literature were synthesized for the Great Lakes Basin (GLB). For the majority of surfaces, fluxes were net positive (evasion). Digital land-cover data were combined with representative evasion rates and used to estimate annual Hgo evasion for the GLB (7.7 Mg/yr). This value is less than our estimate of total Hg deposition to the area (15.9 Mg/yr), suggesting the GLB is a net sink for atmospheric Hg. The greatest contributors to annual evasion for the basin are agricultural (~55%) and forest (~25%) land cover types, and the open water of the Great …

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 …

Shift Towards P Limitation With N Deposition?, K. F. Crowley, B. E. Mcneil, G. M. Lovett, C. D. Canham, C. T. Driscoll

Civil and Environmental Engineering - All Scholarship

Atmospheric nitrogen (N) deposition is altering biogeochemical cycling in forests and interconnected lakes of the northeastern US, and may shift nutrient limitation from N toward other essential elements, such as phosphorus (P). Whether this shift is occurring relative to N deposition gradients across the northeastern US has not been investigated. We used datasets for the northeastern US and the Adirondack sub-region to evaluate whether P limitation is increasing where N deposition is high at two geographic scales, based on N:P mass ratios. Using a model- selection approach, we determined that foliar N for dominant tree species and lake dissolved inorganic …

The Antitheses (Matthew 5:21-48) In The Sermon On The Mount: Moral Precepts Revealed In Scripture And Binding On All People, Amos Winarto Oei

CTS PhD Doctoral Dissertations

While many may agree that the Sermon on the Mount is the epitome of Jesus' ethics, many also recognize that the Sermon is often a riddle. The vastness and variety of literature demonstrates that the interpretation of the Sermon is subject to many disagreements. At the heart of the Sermon of the Mount, the antitheses (Matthew 5:21-48) become one source of polemics in the study of the Sermon. The purpose of this dissertation is to contribute to the scholarship of the Sermon on the Mount by addressing two problems in the study of the antitheses. The first concerns the nature …
