Viability Of Piping Plover Charadrius Melodus Metapopulations, Jonathan H. Plissner, Susan M. Haig

United States Geological Survey: Staff Publications

The meta-population viability analysis package, vortex, was used to examine viability and recovery objectives for piping plovers Charadrius melodus, an endangered shorebird that breeds in three distinct regions of North America. Baseline models indicate that while Atlantic Coast populations, under current management practices, are at little risk of near-term extinction, Great Plains and Great Lakes populations require 36% higher mean fecundity for a significant probability of persisting for the next 100 years. Meta-population structure (i.e. the delineation of populations within the meta-population) and inter-population dispersal rates had varying effects on model results; however, spatially-structured meta-populations exhibited lower viability than …

Waterfowl Research Priorities In The Northern Great Plains, Robert R. Cox, Douglas H. Johnson, Michael A. Johnson, Ronald E. Kirby, Jeffrey W. Nelson, Ronald E. Reynolds

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

It is necessary periodically to identify research priorities so that future research will be directed toward the most pertinent issues in waterfowl ecology and management. To that end, Northern Prairie Wildlife Research Center convened a quorum of experts on the ecology of breeding waterfowl, the Waterfowl Working Group, to 1) develop a mission statement, 2) identify waterfowl research priorities in the northern Great Plains, and 3) determine the frequency for re-identifying research needs. Research needs (nonprioritized) identified by the group and described in detail herein included: 1) determine effects of landscape factors on demographics and recruitment of ducks in the …

Geochemical And Mineralogical Evidence From Eolian Sediments For Northwesterly Mid-Holocene Paleowinds, Central Kansas, Usa, Alan F. Arbogast, Daniel R. Muhs

United States Geological Survey: Staff Publications

A prominent (4500 km²) dune field in the Great Plains is the Great Bend Sand Prairie of south-central Kansas. Dunes here overlie late Quaternary alluvium and were reactivated extensively in the late Holocene. Geomorphic and soil evidence suggests that the most likely eolian sand source is the Arkansas River valley to the northwest. Nevertheless, orientations of stabilized dunes indicate that the most recent dune-forming winds came from the south or southwest, in agreement with modern wind data.

Mineralogy and trace element concentrations in eolian sands of the Great Bend Sand Prairie are similar to those of the Arkansas …

A Surface-Associated Activity Trap For Capturing Water-Surface And Aquatic Invertebrates In Wetlands, Mark A. Hanson, Christiane C. Roy, Ned H. Euliss Jr., Kyle D. Zimmer, Michael R. Riggs, Malcolm G. Butler

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We developed a surface-associated activity trap (SAT) for sampling aquatic invertebrates in wetlands. We compared performance of this trap with that of a conventional activity trap (AT) based on nondetection rates and relative abundance estimates for 13 taxa of common wetland invertebrates and for taxon richness using data from experiments in constructed wetlands. Taxon-specific non-detection rates for ATs generally exceeded those of SATs, and largest improvements using SATs were for Chironomidae and Gastropoda. SATs were efficient at capturing cladocera, Chironomidae, Gastropoda, total Crustacea, and multiple taxa (taxon richness) but were only slightly better than ATs at capturing Dytiscidae. Temporal differences …

Geochemical Variations In Peoria Loess Of Western Iowa Indicate Paleowinds Of Midcontinental North America During Last Glaciation, Daniel R. Muhs, E. Arthur Bettis Iii

United States Geological Survey: Staff Publications

Peoria Loess deposited in western Iowa during the last glacial maximum (LGM) shows distinct geochemical and particle-size variations as a function of both depth and distance east of the Missouri River. Geochemical and particle-size data indicate that Peoria Loess in western Iowa probably had two sources: the Missouri River valley, and a source that lay to the west of the Missouri River. Both sources indicate that LGM paleowinds in western Iowa had a strong westerly component, similar to interpretations of previous workers. A compilation of loess studies in Iowa and elsewhere indicates that westerlv winds were dominant during loess transport …

Effects Of Topography And Soil Properties On Recharge At Two Sites In An Agricultural Field, Geoffrey N. Delin, Richard W. Healy, Matthew K. Landon, John Karl Böhlke

United States Geological Survey: Staff Publications

Field experiments were conducted from 1992 to 1995 to estimate ground water recharge rates at two sites located within a 2.7-hectare agricultural field. The field lies in a sand plain setting in central Minnesota and is cropped continuously in field corn. The sites are located at a topographically high (upland) site and a topographically low (lowland) site in an effort to quantify the effects of depression focusing of recharge. Three site-specific methods were used to estimate recharge rates: well hydrograph analysis, chlorofluorocarbon age dating, and an unsaturated zone water balance. All three recharge methods indicated that recharge rates at the …

Meningeal Worm In Deer From Western Nebraska, David W. Oates, Mauritz C. Sterner, Ed Boyd

Harold W. Manter Laboratory of Parasitology: Faculty Publications

One hundred seventy-eight whitetailed deer (Odocoileus virginianus) and 275 mule deer (Odocoileus hemionus) collected from locker plants in the western 2/3 of Nebraska (USA) in November 1997 were examined for the meningeal worm (Parelaphostrongylus tenuis). Parelaphostrongylus tenuis was identified in 17 (10%) of 168 white-tailed deer and in one (<1%) of 273 mule deer. This is the first naturally occurring infection of P. tenuis recorded in a mule deer.

Phylogeny Of The Ascaridoidea (Nematoda: Ascaridida) Based On Three Genes And Morphology: Hypotheses Of Structural And Sequence Evolution, Steven A. Nadler, Deborah S. S. Hudspeth

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Ascaridoid nematodes parasitize the gastrointestinal tract of vertebrate definitive hosts and are represented by more than 50 described genera. We used 582 nucleotides (83% of the coding sequence) of the mitochondrial gene cytochrome oxidase subunit 2, in combination with published small- and large-subunit nuclear rDNA sequences (2,557 characters) and morphological data (20 characters), to produce a phylogenetic hypothesis for representatives of this superfamily. This combined evidence phylogeny strongly supported clades that, with 1 exception, were consistent with Fagerholm’s 1991 classification. Parsimony mapping of character states on the combined evidence tree was used to develop hypotheses for the evolution of morphological, …

Phylogenetic Relationships Among Species Of Contracaecum Railliet & Henry, 1912 And Phocascaris Høst, 1932 (Nematoda: Ascaridoidea) Based On Nuclear Rdna Sequence Data, Steven A. Nadler, S. D'Amelio, H. P. Fagerholm, B. Berland, L. Paggi

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Nuclear-encoded large-subunit ribosomal DNA sequences were used to infer a phylogenetic hypothesis for 17 taxa (16 nominal species) of the genera Contracaecum and Phocascaris. Phylogenetic trees based on these data have been used to assess the validity of the taxonomic distinction between these genera, which was based on the presence or absence of certain structural features, rather than on explicit hypotheses of evolutionary history. Phylogenetic hypotheses based on parsimony, likelihood, and neighbor-joining analyses of these sequence data strongly support the hypothesis that species of Phocascaris are nested within the clade of Contracaecum species hosted by phocid seals, and are …

Relationships Of Nematodirus Species And Nematodirus Battus Isolates (Nematoda: Trichostrongyloidea) Based On Nuclear Ribosomal Dna Sequences, Steven A. Nadler, Eric P. Hoberg, Deborah S.S. Hudspeth, Lora G. Rickard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Nuclear ribosomal sequence data from the internal transcribed spacers (ITS-1 and ITS-2), 5.8S subunit, and regions of the 18S and 28S genes were used to investigate sequence diversity among geographic samples of Nematodirus battus, and to infer phylogenetic relationships among Nematodirus species. Phylogenetic analysis of these data yielded strong support for relationships among species, depicting Nematodirus helvetianus and Nematodirus spathiger as sister-taxa and a clade of these two species and Nematodirus filicollis. This tree is consistent with caprine bovids as ancestral hosts, with a subsequent host shift to Bovinae in N. helvetianus. Eleven of fourteen N. battus sequences …

Archaeoparasitology, Karl Reinhard

Karl Reinhard Publications

The field devoted to the identification of parasite remains in the archaeological record and the reconstruction of past human-parasite interactions. Parasitic disease has always been a major problem. Recent summaries of the prevalence of parasitic diseases in the world today show that there are 4.5 billion infections with all species of parasitic worm, 1 billion infections with giant intestinal roundworm (Ascaris lumbricoides), 750,000,000 infections with whipworms (Trichuris trichiura), 900,000,000 infections with hookworm (Ancylostoma duodenale and Necator americanus), 657,000,000 infections with filarial worms, 200,000,000 with blood flukes (schistosome species), and 489,000,000 infections with malaria. These infections cause between 1,590,000 to 3,130,000 …

Coprolite Analysis: The Analysis Of Ancient Human Feces For Dietary Data, Karl Reinhard

Karl Reinhard Publications

Although archaeological fieldwork is hot and dirty, the most “earthy” side of the discipline is the laboratory analysis of coprolites. Each coprolite contains the remains of one to several actual meals eaten in prehistory, and analysis of many coprolites provides a picture of ancient diet that is unique in accuracy.

The term coprolite originally referred to fossilized feces in paleontological context. In archaeology, the term broadened to refer to any formed fecal mass, including mineralized, desiccated, or frozen feces and even the intestinal contents of mummies. Coprolites contain the remains of animals (parasites) that lived in the humans, the foods …

Life Cycle Of Calyptospora Funduli (Apicomplexa: Calyptosporidae), John W. Fournie, Wolfgang K. Vogelbein, Robin M. Overstreet, William E. Hawkins

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The taxonomic status of the extraintestinal piscine coccidium Calyptospora funduli is based in part on its requirement of an intermediate host (the daggerblade grass shrimp Palaemonetes pugio). In the present study, grass shrimp fed livers of Gulf killifish (Fundulus grandis) infected with sporulated oocysts of C. funduli exhibited numerous sporozoites suspended in the intestinal contents when fresh squash preparations were examined by light microscopy. Using this method, sporozoites were not seen in intestinal epithelial cells of the grass shrimp or in any other cell types. Ultrastructural examination, however, revealed sporozoites in the cytoplasm of the gut basal …

Boundary Controllability Of Thermoelastic Plates Via The Free Boundary Conditions, George Avalos, Irena Lasiecka

Department of Mathematics: Faculty Publications

Controllability properties of a partial differential equation (PDE) model describing a thermoelastic plate are studied. The PDE is composed of a Kirchoff plate equation coupled to a heat equation on a bounded domain, with the coupling taking place on the interior and boundary of the domain. The coupling in this PDE is parameterized by α > 0. Boundary control is exerted through the (two) free boundary conditions of the plate equation and through the Robin boundary condition of the temperature. These controls have the physical interpretation of inserted forces and moments and prescribed temperature, respectively, all of which act on the …

Opportunities For Family Research In Marketing, Suraj Commuri, James W. Gentry

Department of Marketing: Faculty Publications

Family as a consuming and decision making unit is a central phenomenon in marketing and consumer behavior. However, in the recent past, there has been a decline in interest in family as a unit of analysis. Yet, at the same time, the family -- as an institution -- is undergoing a metamorphosis and currently stands at the threshold of significant transformation. In this paper, we argue that the decreased interest in family as a unit of analysis in marketing is largely due to the fact that many interesting propositions about family as a consuming unit remain outside the current perspective …

Colonial Violence And Trauma In The Works Of Michèle Lacrosil And Ken Bugul, Marie-Chantal Kalisa

French Language and Literature Papers

To what extent can we say that both Lacrosil and Bugul rewrite Fanon? Through the study of Cajou and Ken, respectively the Guadeloupean and the Senegalese female protagonists, this article proposes a way to derive a specifically female perspective on colonial violence. The essay focuses on the two novels, Cajou and Le baobab fou, and examines the effect of colonial epistemological violence and its specific impact on the black female’s subjectivity. The protagonists Ken and Cajou revisit their initial trauma in a quest for knowledge of their historical heritage and engage in a dialogue with Frantz Fanon, representative of black …

Presidential Non-Enforcement Of Constitutionally Objectionable Statutes, Dawn E. Johnsen

Articles by Maurer Faculty

This article, published in Law & Contemporary Problems, was presented at a Duke Law School conference, The Constitution Under Clinton: A Critical Assessment. It examines a recurring, unsettled issue of executive power: how the President best fulfills his constitutional responsibilities when confronted with the enforcement of a statute that he believes is unconstitutional. What should the President do if he believes enforcing a statutory provision would violate the Constitution? Should, for example, a President comply with a congressional command that he believes would violate the constitutional rights of individuals or compromise presidential power? The article examines the two prevailing approaches …

Indeterminate Claims: New Challenges To Self-Determination Doctrine In Yugoslavia, Timothy W. Waters

Articles by Maurer Faculty

Serbia has two autonomous provinces, with nearly identical constitutional and political claims: heavily Albanian Kosovo and ethnically diverse but Serb-majority Vojvodina. One is headed towards some form of internationally recognized independence; the other almost certainly is not, even though calls for its autonomy have been mounting. What makes the difference?

This article examines what the reasons for these different outcomes show about the changing content of self-determination in an environment of persistent ethnic claims. The defining characteristic of self-determination today is its indeterminacy, which allows policymakers to pursue a broader range of policies than was possible in the era of …

A Rejoinder To Abraham Hirsch, Samuel Hollander, Sandra J. Peart

Jepson School of Leadership Studies articles, book chapters and other publications

The dispute between Hollander and Peart, and Hirsch, turns on the nature and role of verification in Mill’s perception of the appropriate method for Political Economy. Professor Hirsch maintains against us that, for Mill, the models constructed by political economists are insulated from verification. His case is based on two counterclaims. First, that when Mill writes of “verification” in Book III of the Logic, he has in mind a procedure differing from that appropriate for Political Economy, which allows only “indirect verification” (outlined in Book VI). Hirsch finds that Hollander and Peart confuse the two. Secondly, since the contexts …

A Constitutional Conundrum: The Resilience Of Tribal Sovereignty During American Nationalism And Expansion: 1810-1871, David E. Wilkins

Jepson School of Leadership Studies articles, book chapters and other publications

Judge Michael Hawkins addresses a number of important issues in his essay on John Quincy Adams' evolving understanding and relationship with slavery and the variegated role that law played in the politics of slavery and the slavery of politics. The essay demonstrates the importance of human personality in influencing and being influenced by political and legal processes. At its heart, the Article is a legal and historical study of the moral dimension and inherent contradictions facing Adams, in particular, and the American Republic, in general, regarding the existence and persistence of the institution of slavery in a nation built upon …

An Inquiry Into Indigenous Political Participation: Implications For Tribal Sovereignty, David E. Wilkins

Jepson School of Leadership Studies articles, book chapters and other publications

When we set out to examine the various forms and patterns of indigenous political participation in the three polities they are connected to—tribal, state, and federal—we are stepping into a most complicated subject matter. It is complicated in large part because Indians are citizens of separate extra-constitutional nations whose members have only gradually been incorporated in various ways by various federal policies and day to day interactions with non-Indians. Tribal nations, of course, have never been constitutionally incorporated and still retain their standing as separate political bodies not beholden to either federal or state constitutions for their existence.
