Lucky Pennies And Four Leaf Clovers: Young Children's Understanding Of Superstitions, Christy Bryce
Masters Theses & Specialist Projects
The development of organized, explanatory systems of knowledge is an integral part of human nature; it allows us to categorize objects and events and to make predictions based on our experiences. In our society, the quest for answers to the questions "How?" and "Why?" begins early in life. By the preschool years, children are actively seeking and providing explanations for an abundance of physical and social events, and they are developing knowledge of causal forces at work in the environment (Bullock, Gelman, & Baillargeon, 1982; Rosengren & Hickling, 1999). Paradoxically, at about the same age at which children demonstrate they …

Storm Deposition Of Pisoids In The Humboldt Oolite Member Of The Gilmore City Formation (Mississippian), North-Central Iowa, Shawn C. Thomas, John R. Groves
Storm Deposition Of Pisoids In The Humboldt Oolite Member Of The Gilmore City Formation (Mississippian), North-Central Iowa, Shawn C. Thomas, John R. Groves
Journal of the Iowa Academy of Science: JIAS
Pisoids (concentrically laminated carbonate grains, > 2 mm in diameter) are abundant in the upper Humboldt Oolite Member of the Gilmore City Formation (Mississippian). Their cortices are isopachous and nuclei include both intraclasts and fragments of preexisting
pisoids. They occur both as floating grams m a fine grainstone matrix and concentrated at the bases of distinct layers that may be crudely graded beds. Sorting characteristics and the presence of broken and abraded pisoids suggest not only their origin as primary free grams, but also storm influence in the deposition of local pisolite layers. Regionally, the upper Humboldt Oolite is characterized by …

Effects Of Field Size And Landscape Composition On Grassland Birds In South-Central Iowa, David Joseph Horn, Rolf R. Koford, Malinda L. Braland
Effects Of Field Size And Landscape Composition On Grassland Birds In South-Central Iowa, David Joseph Horn, Rolf R. Koford, Malinda L. Braland
Journal of the Iowa Academy of Science: JIAS
Many species of grassland birds have been shown to avoid smaller fields. The avoidance of smaller fields, however, has not been consistently reported; avoidance may occur in one study, but not in another. To examine one possible reason for these inconsistencies, we examined how landscape composition influenced the relations between occurrence or abundance and field size. The study took place during the 1998 breeding season on 44 Conservation Reserve Program (CRP) fields located in Adair, Ringgold, and Union counties. The relations between occurrence, abundance, and field size were not influenced by landscape composition for any species.

Factors Influencing The Occurrence Of Birds That Use Feeders In Iowa, David Joseph Horn, Steve E. Fairbairn, Richard J. Hollis
Factors Influencing The Occurrence Of Birds That Use Feeders In Iowa, David Joseph Horn, Steve E. Fairbairn, Richard J. Hollis
Journal of the Iowa Academy of Science: JIAS
Since its inception in 1984, data from the annual Iowa "Winter Bird Feeder Survey" have provided valuable information about birds that use feeders in Iowa such as spatial and temporal population trends. Using data from the 1988 and 1994 Surveys, we examined how the occurrence of bird species that use feeders was influenced by geographic location, the habitat surrounding a house, and the types of seeds offered at a house. Of the 23 species examined, the occurrence of 8 species was influenced by latitude, 22 species were influenced by the habitat surrounding the house, and 22 species were influenced by …
Inheritance Of Gray Leaf Spot Resistance In Corn, J. M. D. Crowley, A. R. Hallauer, C. A. Martinson
Inheritance Of Gray Leaf Spot Resistance In Corn, J. M. D. Crowley, A. R. Hallauer, C. A. Martinson
Journal of the Iowa Academy of Science: JIAS
Gray leaf spot disease, caused by Cercospora zeae-maydis Tehon and Daniels, has become a significant disease in Iowa corn (Zea mays L.) production. Incidence of gray leaf spot has increased with the increased use of conservation tillage practices. The inheritance of resistance to gray leaf spot was studied via use of generation mean analyses for five crosses and via use of 100 S1 progenies developed from an F2 population. Experiments were conducted at two locations that included either natural or artificial inoculation with C. zeae-maydis spores. Additive and dominance effects were significant in nearly all instances. Heritability for …
Fungi And Diseases Associated With Cultivated Switchgrass In Iowa, C. E. Gravert, G. P. Munkvold
Fungi And Diseases Associated With Cultivated Switchgrass In Iowa, C. E. Gravert, G. P. Munkvold
Journal of the Iowa Academy of Science: JIAS
Switchgrass (Panicum virgatum L.) is a native perennial prairie grass that is now cultivated as a forage crop and a biomass crop for renewable energy. Biomass yields of switchgrass in southern Iowa have recently dropped significantly in some fields and the reduction has been attributed to disease. A disease survey was conducted in 1999 to assess the prevalence of major diseases in Chariton Valley switchgrass production. There were disease symptoms present on switchgrass plants in each field and thirteen fungal species were identified from leaf, stem, and root samples. Two pathogenic fungi, Tilletia maclaganii and Colletotrichum graminicola, were present in …
Book Review - Prairie Birds: Fragile Splendor In The Great Plains, Neil P. Bernstein
Book Review - Prairie Birds: Fragile Splendor In The Great Plains, Neil P. Bernstein
Journal of the Iowa Academy of Science: JIAS
Paul A. Johnsguard has established himself as one of the most prolific natural history writers in the recent past. Indeed, before I could finish reading Prairie Birds, the University of Kansas Press sent me The Nature of Nebraska, also by Johnsguard. These works follow closely after This Fragile Land, A Natural History of the Nebraska Sandhills (1995), which I favorably reviewed a few years ago, also about the Great Plains. It goes without saying, that there is a fair amount of overlap in these works, both in the subject matter and the illustrations. Rather than criticize the overlap among these …

The Unionid Mussels Of The Upper Iowa And Turkey River Watersheds, Jim Eckblad, Brett Ostby, Karis Tenneson
Journal of the Iowa Academy of Science: JIAS
The Iowa driftless region occupies an area of about 9,000 km2 in the northeastern corner of Iowa and is drained by relatively old entrenched meandering streams. The Upper Iowa River and Turkey River are the largest of these streams. During the period from June, 1999 to October, 2000, a total of 193 sites were surveyed for mussels from the Upper Iowa River, the Turkey River, and their main tributaries. Surveys were conducted by hand using a 10 m bank-to-bank search at each site. Data analysis was facilitated using ArcView GIS. The presence of mussels was recorded at 75% of …

African American Racial Identity And Sport, Keith Harrison
African American Racial Identity And Sport, Keith Harrison
EGS Content
The purpose of this paper is to attempt to synthesize and apply African American racial identity theory and related research to the development of sport and physical activity patterns and preferences in African American youth. Historically the African American over-representation in particular sports phenomena has been examined genetically, anthropocentrically, physiologically, sociologically, and psychologically. The profusion of explanations is a testimony to the complexity of this phenomena. This manuscript provides yet another compelling perspective. Cross [(1995) The psychology of Nigrescence: revising the Cross Model, in: J.G. PONTEROTTO et al. (Eds) Handbook of Multicultural Counseling (Thousand Oaks, CA, Sage)] outlines the metamorphic …
Scholar Or Baller In American Higher Education? A Visual Elicitation And Qualitative Assessment Of The Studentathlete's Mindset, Keith Harrison
Scholar Or Baller In American Higher Education? A Visual Elicitation And Qualitative Assessment Of The Studentathlete's Mindset, Keith Harrison
EGS Content
Eminent scholar Harry Edwards (2000) has articulated three major realities of African American males in sports: a) The presumption of innate, race-linked black athletic superiority and intellectual deficiency; b) media propaganda portraying sports as a broadly accessible route to African American social and economic mobility; and c) a lack of comparably visible, high-prestige African American role models beyond the sports arena. Driven by labeling theory (Becker, 1963; Goffman, 1959), eight African American male student athletes were surveyed and interviewed. The last two points of Edwards' scholarship were investigated. "We have pretty good historical data and quantitative data about African American …

Identification And Distribution Of Masked And Hayden's Shrews (Genus Sorex) In Iowa, Howard P. Whidden, Alison W. Ray, John B. Bowles
Identification And Distribution Of Masked And Hayden's Shrews (Genus Sorex) In Iowa, Howard P. Whidden, Alison W. Ray, John B. Bowles
Journal of the Iowa Academy of Science: JIAS
Masked shrews (Sorex cinereus) and Hayden's shrews (S. haydeni) are both reported from Iowa, but the two species are difficult to tell apart and their relative distributions in Iowa have been unclear. We took 13 skull measurements and examined 2 qualitative features on more than 300 specimens of Sorex from Iowa. The vast majority of our specimens could be identified easily by cranial measurements, and more than half could be identified by the relative position of the maxillary plate. We found no evidence for intergradation between the two species. Masked shrews are present throughout most of Iowa, whereas Hayden's shrews …
Soybean Canopy Gap Influence On Velvetleaf Seed Production, Shawn R. Wright, Micheal D. K. Owen, Douglas D. Buhler
Soybean Canopy Gap Influence On Velvetleaf Seed Production, Shawn R. Wright, Micheal D. K. Owen, Douglas D. Buhler
Journal of the Iowa Academy of Science: JIAS
Gaps in the soybean row provide locations for velvetleaf (Abutilon theophrasti) plant growth. Gap width, and velvetleaf plant location within the gap, were investigated for effect on seed production. There was no significant difference in velvetleaf capsule production between plants that grew either centered in a gap or at the western end of a gap in east-west oriented soybean rows. Also, there was no difference in plant survival, emergence through the soybean canopy, flowering, locule number per capsule, or average seed weight of velvetleaf based on gap width. However, there was a difference in capsule production based on gap width. …

Effects Of Cattle Grazing On Woodlands In Central Iowa, Cathy Mabry
Effects Of Cattle Grazing On Woodlands In Central Iowa, Cathy Mabry
Journal of the Iowa Academy of Science: JIAS
Iowa's forests have undergone a dramatic decline in area since settlement by Europeans. Most of the remaining forests have been degraded by an assortment of human impacts, with cattle grazing the most prominent among them. Using a matched pairs study designed to control for environmental differences among plots, I examined the impact of cattle grazing on the forest understory, canopy trees, and tree regeneration. There were distinct groups of understory species associated with ungrazed and grazed plots. Species associated with ungrazed plots were all native and tended to be perennial herbs with fleshy roots. Ungrazed plots also had species preferring …
Science Safety Status In Iowa Schools, Gerlovich A. Jack, Rahul Parsa, Bruce Frana, Theresa Stiner
Science Safety Status In Iowa Schools, Gerlovich A. Jack, Rahul Parsa, Bruce Frana, Theresa Stiner
Journal of the Iowa Academy of Science: JIAS
Between May and December 2001, 574 Iowa science teachers participated in a statewide science safety project supported by financial assistance from the Iowa Department of Natural Resources. Part one of the project focused on assessing the status of safety in Iowa secondary science programs. Part two was to provide teachers with information, tools, and training to address the identified needs. Three safety concerns were identified: one was associated with the age of lab facilities and two were related to safety training of teachers.

Book Review - North American Box Turtles: A Natural History, Neil P. Bernstein
Book Review - North American Box Turtles: A Natural History, Neil P. Bernstein
Journal of the Iowa Academy of Science: JIAS
While I have only studied box turtles for four years, from the beginning, I was quickly impressed at the many studies and observations that had been published on North American box turtles. At the same time, I was also frustrated by the lack of syntheses of the material. For the beginning researcher or interested layperson, organizing the studies into a cohesive whole was daunting, and I attempted my own loose compilation that took me most of a summer. However, there is now a new book that provides the background and overview that I sought. C. Kenneth Dodd, a longtime researcher …

Book Review - The Guide To Iowa's State Preserves, Cornelia F. Mutel
Journal of the Iowa Academy of Science: JIAS
The Iowa State Preserves System gives the highest protection afforded by law to sites "dedicated for maintenance as nearly as possible in [their] natural condition." To date, ninety sites have been dedicated as biological, geological, archaeological, scenic, or historic preserves, declaring that such use is the site's "highest, best, and most important use for the public benefit" (State Preserves Act of 1965). In a state as dramatically altered as Iowa, such remnants are of intense interest to professional and amateur naturalists of all inclinations, as well as to anyone who appreciates nature. Yet understanding the basic qualities of these preserve …
