Enhancing Iowa High School Students' Transition To College, K. E. Lassila, L. C. Rule, C. Lee, R. J. Driggs, G. Fulton, M. Skarda, J. Torres Y Torres
Enhancing Iowa High School Students' Transition To College, K. E. Lassila, L. C. Rule, C. Lee, R. J. Driggs, G. Fulton, M. Skarda, J. Torres Y Torres
Journal of the Iowa Academy of Science: JIAS
We present our studies of the transitions of Iowa science students from high school to post-secondary colleges. Our report summarizes information and impressions from dealing with thousands of new students arriving at our six colleges, along with meetings and discussions with high school science teachers to add their viewpoints into our considerations. Feedback from community college, four year college, and high school science teachers highlighted the following five study issues and needs for improving student transitions from high school to college science: 1) Better math preparation is needed; 2) More work with inquiry-based learning rather than with facts and memorization …
The Freshwater Mussels (Mollusca: Bivalvia: Unionidae) Of The Channelized Missouri River, Ellet Hoke
The Freshwater Mussels (Mollusca: Bivalvia: Unionidae) Of The Channelized Missouri River, Ellet Hoke
Journal of the Iowa Academy of Science: JIAS
The lower Missouri River has historically been viewed as a fauna! barrier for unionids due to high sediment load. However this survey of the lower (channelized) Missouri River documented the presence of 14 unionid species and the exotic Corbicula fluminea (Muller, 1774). Unionids are present in stable substrates sheltered from the effects of the river's strong currents. Analysis of early literature on the Missouri River suggests reports of an absence of unionids were not based upon thorough fieldwork, and the most commonly cited rationale for their reported absence, the high sediment load in the river, is not convincing. Pre-1938 unionid …

Gully And Stream Bank Erosion In Three Pastures With Different Management In Southeast Iowa, George N. Zaimes, Richard C. Schultz, Mustafa Tufekcioglu
Gully And Stream Bank Erosion In Three Pastures With Different Management In Southeast Iowa, George N. Zaimes, Richard C. Schultz, Mustafa Tufekcioglu
Journal of the Iowa Academy of Science: JIAS
Gully and stream banks can be major sources of sediment and nutrients to surface waters, both major water quality problems in the United States. Sediment may also carry phosphorus to surface waters, the primary limiting nutrient causing eutrophication. Overgrazing can induce gully and stream bank erosion by reducing vegetation cover that weakens bank soil resistance to stream water flow. This study examines stream and gully bank erosion adjacent to continuous (CP), rotational (RP) and intensive rotational (IP) pastures, grazed by beef cattle in southeast Iowa. Stream and gully bank erosion were measured by: a) surveying the extent of the severely …

Dr. Lois Hattery Tiffany (1924-2009): In Memoriam, Deborah Q. Lewis
Journal of the Iowa Academy of Science: JIAS
Dr. Lois Hartery Tiffany, Distinguished Professor Emerita, Department of Ecology, Evolution and Organismal Biology, Iowa State University, Ames, Iowa, died on 6 September 2009. Dr. Tiffany was an outstanding mycologist and teacher. Held in high regard by the public as "Iowa's Mushroom Lady" and known by many students, colleagues and friends as "Dr. T.," she was the matriarch of the Botany Department (now the Department of Ecology, Evolution and Organismal Biology) at Iowa State.

Som Loss And Soil Quality In The Clear Creek, Ia, A. N. Thanos Papanicolaou, Christopher G. Wilson, Ozan Abaci, Mohamed Elhakeem, Mary Skopec
Som Loss And Soil Quality In The Clear Creek, Ia, A. N. Thanos Papanicolaou, Christopher G. Wilson, Ozan Abaci, Mohamed Elhakeem, Mary Skopec
Journal of the Iowa Academy of Science: JIAS
The Clear Creek, IA Experimental Watershed (CCEW), which drains to the Iowa River, experiences severe surface erosion due to a combination of high slopes, erodible soils, and extensive agriculture. Concurrent with soil loss is the removal of Soil Organic Matter (SOM). High values of SOM have been related to soil quality; therefore, excessive SOM loss corresponds to degrading soil health. Soil quality assessments are important tools for evaluating management practices in agricultural systems; however, it is difficult to measure soil quality directly at the watershed scale because it varies with a number of site-specific soil characteristics. The coupling of soil …
Aryl Ethers From Arenediazonium Tetrafluoroborate Salts: From Neat Reactions To Solvent-Mediated Effects, James A. Shriver, Daniel P. Flaherty, Cameron C. Herr
Aryl Ethers From Arenediazonium Tetrafluoroborate Salts: From Neat Reactions To Solvent-Mediated Effects, James A. Shriver, Daniel P. Flaherty, Cameron C. Herr
Journal of the Iowa Academy of Science: JIAS
A general procedure for the synthesis of various aryl ethers via the thermal decomposition of benzenediazonium tetrafluoroborate salts is described. Studies performed in neat alcohol at 60°C gave aryl ethers in yields ranging from 0-73%. Upon completion of a series of reactions, the effect of solvent was explored to expand the scope and relevance of this procedure. It was found that even solvents that are traditionally non-nucleophilic gave rise to products including bi-aryls and N-aryl acetamides. The utilization of an ionic liquid, l-butyl-4-methylpyridinium tetrafluoroborate, resulted in yields comparable to reactions performed in neat alcoholic solvents.
The Effects Of Varying Seeding Rates Of Bouteloua Curtipendula And Mowing On Native Plant Establishment In A New Prairie Reconstruction, Ryan Leon Welch
The Effects Of Varying Seeding Rates Of Bouteloua Curtipendula And Mowing On Native Plant Establishment In A New Prairie Reconstruction, Ryan Leon Welch
Dissertations and Theses @ UNI
A major problem early in prairie reconstruction is weed competition. Research has shown that mowing in the first year can increase establishment and survival of prairie plants. The use of nurse crops (companion crops) has been suggested as an alternative to mowing for weed suppression. The goal of this study was to examine various seeding rates of B. curtipendula, as a nurse crop in mowed and unmowed plots to determine if it suppressed weeds and aided in the establishment of natives. We hypothesized that increasing the seeding rate of B curtipendula will reduce weed growth and promote an increase in …

Pollution Swapping: The Effect Of Phosphorus Sequestration On Denitrification In Wetland Sediments, Nathaniel Femi Adegboyega
Dissertations and Theses @ UNI
Surface water quality is currently one of the most important environmental issues facing the state of Iowa since the ecological and recreational health of water bodies are threatened by non-point pollution. Most of Iowa's lakes are polluted because of their high concentration of nutrients, often phosphorus (P), which leads to excessive algal growth (eutrophication). To prevent eutrophication, it is necessary to prevent P from entering surface waters or to sequester (make unavailable to algae) the P that is already in the water body. One method to achieve this is to introduce substances that can tightly fix P (sorption).

A Light Unto Our Path: Toward A Mutual Understanding Of Fundamentalist Christianity And Science, Kassidy K. Lyons
Honors Program Theses
My research into the Christian fundamentalist and scientific worldviews shows that existing hostility between the two can be attributed to extremists on either side. Such polarization can be a hindrance to all involved by inhibiting scientific learning and disregarding valid methods to signify and understand one’s place in the world. I explore each worldview and its validity as well as provide examples of how each can be harmful when taken to the extreme. I then outline philosophies by Stephen Jay Gould, Michael Ruse, Marcus Borg, Karl Popper and others who deny extremism and will allow an individual to find middle …
