Are You What You Eat? An Inside Look At High-Tech Food, Roxanne Greitz Miller

Education Faculty Articles and Research

If we abide by the familiar saying "you are what you eat," it is understandable that people may be concerned with the incredible advances in food science technology and their possible impacts on human health. For example, in recent years high-tech scientific processes such as genetic modification, irradiation, and cloning have all been used to increase the safety of food supply, create foods that are more appealing to eat and easier to produce, and increase crop yields. This article will summarize a few hot topics in food science, address what is currently known about the safety of these processes, and …


Does Increasing Biology Teacher Knowledge Of Evolution And The Nature Of Science Lead To Greater Advocacy For The Teaching Of Evolution In Schools?, Ross Nehm, Irvin Sam Schonfeld Jan 2007

Does Increasing Biology Teacher Knowledge Of Evolution And The Nature Of Science Lead To Greater Advocacy For The Teaching Of Evolution In Schools?, Ross Nehm, Irvin Sam Schonfeld

Publications and Research

This study investigated whether or not an increase in secondary science teacher knowledge about evolution and the nature of science gained from completing a graduate-level evolution course was associated with greater preference for the teaching of evolution in schools. Forty-four precertified secondary biology teachers participated in a 14-week intervention designed to address documented misconceptions identified by a precourse instrument. The course produced statistically significant gains in teacher knowledge of evolution and the nature of science and a significant decrease in misconceptions about evolution and natural selection. Nevertheless, teachers' postcourse preference positions remained unchanged; the majority of science teachers still preferred …

Using Literature And Innovative Assessments To Ignite Interest And Cultivate Critical Thinking Skills In An Undergraduate Neuroscience Course, Eileen Lynd-Balta Jul 2006

Using Literature And Innovative Assessments To Ignite Interest And Cultivate Critical Thinking Skills In An Undergraduate Neuroscience Course, Eileen Lynd-Balta

Biology Faculty/Staff Publications

Science education reform initiatives emphasize 1) the value of concepts over facts; 2) the benefits of open-ended, inquiry-based problem-solving rather than protocols leading to a single correct answer; and 3) the importance of a multidisciplinary approach to teaching that is not confined by departmental boundaries. Neuroscientists should be at the forefront of this movement by the very nature of the discipline we study. Neuroscience is a relatively new field that integrates diverse subjects (anatomy, physiology, pharmacology, molecular biology, computer science, and psychology) and experimental advances are constantly changing and expanding our understanding of brain function. How can we convey this …

Winter Bird Use Of Conservation Reserve Program Fields Harvested For Biomass, Les D. Murray, Louis B. Best Jan 2006

Winter Bird Use Of Conservation Reserve Program Fields Harvested For Biomass, Les D. Murray, Louis B. Best

Journal of the Iowa Academy of Science: JIAS

As Conservation Reserve Program (CRP) contracts expire, many fields may be returned to agricultural production. Growing switchgrass (Panicum virgatum) as a biomass fuel is an alternative to returning fields to rowcrops. CRP fields provide winter cover for birds, but the harvest of biomass would remove most of the cover and affect bird use of the fields. We estimated winter bird abundances in nonharvested, total-harvested, and partially (strip) harvested switchgrass fields in southern Iowa. Song sparrows (Melospiza melodia) were observed only in strip-harvested fields and ring-necked pheasants (Phasianus colchicus) were observed only in nonharvested fields and uncut areas of strip-harvested fields. …


Changes In Land Cover And Breeding Bird Populations With Restoration Of Riparian Habitats In East-Central Iowa, Thomas J. Benson, James J. Dinsmore, William L. Hohman Jan 2006

Changes In Land Cover And Breeding Bird Populations With Restoration Of Riparian Habitats In East-Central Iowa, Thomas J. Benson, James J. Dinsmore, William L. Hohman

Journal of the Iowa Academy of Science: JIAS

Conversion of Midwestern riparian areas for agricultural production has greatly altered their function and suitability for birds and other wildlife. Recently, however, restoration of riparian functions has been a major focus of land management agencies in the Midwest. We used historic land-use data to describe land-cover changes since European settlement and the subsequent effects of habitat restoration efforts on the landscape along a section of the Iowa River in east-central Iowa. We then used bird-density data collected in a subset of the study area in 2001 and 2002 to estimate changes in breeding bird populations of the entire study area …

Research Plan And Preliminary Results - A Field Research Site For Emerging Contaminants In Iowa, Douglas J. Schnoebelen, Dana W. Kolpin, Larry B. Barber, Edward T. Furlong, Michael M. Meyer, Mary Skopec Jan 2006

Research Plan And Preliminary Results - A Field Research Site For Emerging Contaminants In Iowa, Douglas J. Schnoebelen, Dana W. Kolpin, Larry B. Barber, Edward T. Furlong, Michael M. Meyer, Mary Skopec

Journal of the Iowa Academy of Science: JIAS

Research has recently documented the prevalence of a wide variety of pharmaceuticals and other emerging contaminants (ECs) in streams across the United States. Wastewater treatment plants (WWTPs) have been found to be an important source and collection point of ECs to streams as many ECs are incompletely removed during treatment. To investigate the complex instream processes (e.g., dilution, sorption, degradation, dispersion, etc.) chat can affect ECs following their input from a WWTP and determining if such input is having an effect on the aquatic ecosystem requires the integration of multi-disciplinary efforts at a carefully selected field site. Preliminary work has …


The Honey Creek Member: A New Holocene Alluvial Stratigraphic Unit In The Midwest, Jeremy S. Dillon, Rolfe D. Mandel Jan 2006

The Honey Creek Member: A New Holocene Alluvial Stratigraphic Unit In The Midwest, Jeremy S. Dillon, Rolfe D. Mandel

Journal of the Iowa Academy of Science: JIAS

This paper describes the type locality and type section for the Honey Creek Member, a stratigraphic unit first recognized in the Honey Creek drainage in southeastern Nebraska. The alluvial chronology for Honey Creek basin is similar to the regional chronology of streams in the Midwest, and all of the formal members of the DeForest Formation occur in the basin. However, the lithology of one unit, the Honey Creek Member, does not correlate with any of the formally recognized members of the DeForest Formation. The Honey Creek Member is composed of grayish brown silt loam overbank facies coarsening downward to a …

Use Of Artificial Enclosures To Determine The Survival Of Rana Pipiens Larvae In Upper Midwestern Agricultural Ponds, Joshua M. Kapfer, Mark B. Sandheinrich, Melinda G. Knutson Jan 2006

Use Of Artificial Enclosures To Determine The Survival Of Rana Pipiens Larvae In Upper Midwestern Agricultural Ponds, Joshua M. Kapfer, Mark B. Sandheinrich, Melinda G. Knutson

Journal of the Iowa Academy of Science: JIAS

Amphibians in the upper Midwest use agricultural ponds for breeding. Unfortunately, the risks (both direct and indirect) associated with using these ponds are poorly understood in both amphibian adults and larvae. In order to quantify these risks, we performed a comparison of larval survival rates between agricultural and natural ponds in southeastern Minnesota during the spring and summer of 2001. During this time, larval survival was observed in Rana pipiens tadpoles raised through metamorphosis in enclosures placed in agricultural and natural ponds. In addition, we measured the levels of nutrients commonly linked with agricultural ponds (i.e., ammonia, total phosphorous, and …


Silicification Of Corals, Stromatoporids, And Brachiopods At The Weathered Surface Within The Devonian-Age Little Cedar Formation (Solon And Rapid Members) In Eastern Iowa, Adam L. Majeski, Paul L. Garvin Jan 2006

Silicification Of Corals, Stromatoporids, And Brachiopods At The Weathered Surface Within The Devonian-Age Little Cedar Formation (Solon And Rapid Members) In Eastern Iowa, Adam L. Majeski, Paul L. Garvin

Journal of the Iowa Academy of Science: JIAS

Diagenesis of fossils contained in middle-Devonian limestones was studied at the Troy Mills and Robins quarries in Linn County, Iowa and at the Four County and Ernst quarries in Johnson County, Iowa. Fossils located at weathered bedrock surfaces were preferentially silicified, and the silicification affected corals, stromatoporids and, to a limited extent, brachiopods, but not other fossils or the host rock. The siliceous horizon extends no more than a few centimeters below the weathered surfaces, suggesting that silicification was constrained by them. Silica for silicification might have come from a variety of sources, including sponge spicules or radiolarian tests, insoluble …
