Doping Of A One-Dimensional Mott Insulator: Photoemission And Optical Studies Of Sr2cu03+Δ, Tim Kidd, T. Valla, P. D. Johnson, K. W. Kim, G. D. Gu, C. C. Homes

Faculty Publications

Angle-resolved photoemission and optical spectroscopy are used to probe the electronic structure of the one-dimensional Mott insulator Sr₂CuO_3+δ, both at half-filling and with small concentrations of excess oxygen doping. Spin-charge separation can be seen as evidenced by the existence of spinon and holon branches in the photoemission spectra. Optical studies reveal no significant doping dependence, while photoemission studies show a large energy shift in the spinon and holon states with respect to the main valence band states which remain nearly unaffected. The results suggest the excess dopant carriers are incorporated solely within the one-dimensional Hubbard band …

Using Landscape History And Baseline Data In The Restoration Of A Midwestern Savanna, Andrew P. Rayburn, Annabel L. Major

Journal of the Iowa Academy of Science: JIAS

Over one hundred and fifty years of Euro-American settlement has dramatically altered Midwestern landscapes, resulting in the widespread conversion of native habitat. Numerous opportunities to conduct ecological restoration exist within the Midwest, with the potential to increase habitat and landscape heterogeneity, secure critical ecosystem services, and provide opportunities for research and education. Site history is an important consideration for most restoration projects, and multiple sources of historical data may be required to unravel the complicated history of intensively used Midwestern landscapes. The collection of baseline data is another significant component of most restoration projects, allowing for an evaluation of community …

Pre-Settlement Vegetation At Casey's Paha State Preserve, Iowa, Reid J. Leichty, Steven H. Emerman, Lyndon R. Hawkins, Michael J. Tiano

Journal of the Iowa Academy of Science: JIAS

Paha are loess-capped ridges standing 10-30 m above the surrounding plain of the Iowan Surface. Although Iowa was almost entirely covered with prairie and wetlands just prior to Euro-American settlement, the paha are believed to have been forested based on soil types and on early vegetation maps. The objective of this study was to find evidence that paha were forested by measuring the δ13C value of humin, the fraction of soil organic matter that is insoluble in acid and base. Previous work has shown that humin retains the δ13C signature of vegetation on a 1000-year time scale, as opposed to …

Assessment Of Smallmouth Bass Populations In Iowa Interior Rivers, Andrew C. Jansen, Michael C. Quist, Jeff Kopaska

Journal of the Iowa Academy of Science: JIAS

Smallmouth bass Micropterus dolomieu are a popular sport fish throughout North America and occupy an important ecological role as top predators in aquatic systems. Despite the importance of smallmouth bass, knowledge of their population structure and dynamics in Iowa interior rivers is limited. The objective of this study was to describe population dynamics (e.g., relative abundance, size and age structure, growth, mortality) of smallmouth bass in six Iowa rivers. Smallmouth bass were sampled from the Upper Iowa, Maquoketa, and Wapsipinicon rivers in northeast Iowa and the Des Moines, Iowa, and South Skunk rivers in central Iowa using electrofishing during the …

Observations On The Distribution And Status Of Western Sand Darter, Spotted Gar, And Skipjack Herring In Iowa Rivers, Travis E. Neebling, Michael C. Quist

Journal of the Iowa Academy of Science: JIAS

This paper describes new records of western sand darter (Ammocrypta clara), spotted gar (Lepisosteus oculatus), and skipjack herring (Alosa chrysochloris) in Iowa's interior rivers. A western sand darter was collected from the Cedar River, Benton County, in 2007. Western sand darters are occasionally collected from the upper Mississippi River (UMR), but have not been sampled in interior rivers since 1958. Two spotted gar were collected from the Des Moines River, Polk and Wapello counties, in 2007. Two spotted gar were sampled from the UMR in 2000, but no spotted gar have been previously recorded from Iowa's interior rivers. A skipjack …

Ant Diversity In Two Southern Minnesota Tallgrass Prairie Restoration Sites, Pamela M. Kittelson, Monica Paulson Priebe, Phillip J. Graeve

Journal of the Iowa Academy of Science: JIAS

There is little basic information about ant species richness and abundance in tall grass prairie restorations despite the importance of ants to plant community structure and function. We compared ant abundance and richness, vascular plant cover and richness, and soil compaction at two southern Minnesota grassland restoration sites, a prairie reconstruction and a prairie remnant undergoing rehabilitation. We collected a total of 3,523 ants from 12 different species. Plant species richness ranged from 45 in the prairie reconstruction to 95 in the remnant prairie. We found five more species of ants and significantly higher mean ant species richness per plot …

Selecting U.S. Senators By The Original Method: Intersecting Mathematics And Social Studies, Bonnie H. Litwiller, David R. Duncan

Faculty Publications

Mathematics teachers are concerned with incorporating connections with other academic areas in their mathematics curriculum. Social science provides a rich source of data which can be collected, organized, and interpreted by mathematics students. These data become of particular interest to many students if they involve political questions and processes.
