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 …

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

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 …

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 …

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 …

A Proposed Undergraduate Bioinformatics Curriculum For Computer Scientists, Travis E. Doom, Michael L. Raymer, Dan E. Krane, Oscar Garcia

Kno.e.sis Publications

Bioinformatics is a new and rapidly evolving discipline that has emerged from the fields of experimental molecular biology and biochemistry, and from the the artificial intelligence, database, and algorithms disciplines of computer science. Largely because of the inherently interdisciplinary nature of bioinformatics research, academia has been slow to respond to strong industry and government demands for trained scientists to develop and apply novel bioinformatics techniques to the rapidly-growing, freely-available repositories of genetic and proteomic data. While some institutions are responding to this demand by establishing graduate programs in bioinformatics, the entrance barriers for these programs are high, largely due to …

Multi-Dimensional Regression Analysis Of Time-Series Data Streams, Yixin Chen, Guozhu Dong, Jiawei Han, Benjamin W. Wah, Jianyong Wang

Kno.e.sis Publications

Real-time production systems and other dynamic environments often generate tremendous (potentially infinite) amount of stream data; the volume of data is too huge to be stored on disks or scanned multiple times. Can we perform on-line, multi-dimensional analysis and data mining of such data to alert people about dramatic changes of situations and to initiate timely, high-quality responses? This is a challenging task.

In this paper, we investigate methods for online, multi-dimensional regression analysis of time-series stream data, with the following contributions: (1) our analysis shows that only a small number of compressed regression measures instead of the complete stream …

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

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 - 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 …

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

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

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.

A Review Of Systems: New Paradigms For The Human Sciences, Martin Zwick

Complex Systems Faculty Publications and Presentations

This essay is a selective review of Systems: New Paradigms for the Human Sciences, edited by Gabriel Altmann and Walter A. Koch (Berlin: Walter de Gryter, 1998). It is selective because it is impossible to engage such a varied collection of systems-theoretic essays in a review of reasonable length. To invoke a relevant dialectical idea: the characteristic strength of any system is often also its characteristic weakness. One strength and weakness of the systems field is its great diversity, and this diversity is reflected in this volume by the range of subjects addressed in its 27 articles. I will not …

Missoula Ecopaws: Environmental Incentive Program To Combat Environmental Inaction, Jaymie Sanders, Valayna Cannon, Katy Mccumber, Hattie Ransom

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Climate change has had a drastic impact on the planet on a biological, political, and socioeconomic level. The excessive consumption of natural resources and human-induced pollution has contributed to rising temperatures, intensified weather patterns, and an increase in natural disasters (Nations, 2019). This has led to high levels of eco-anxiety and grief in younger generations, driven by psychological factors, misinformation, and governmental resistance to meaningful change which has influenced inaction in individuals (Hickman et al, 2021). In order to address these growing concerns, we have created a rewards program for our campus community to encourage eco-positive behavior. Missoula EcoPaws is …

Ocean: An Integrated Curriculum Unit, Institute For The Development Of Gifted Education, Ricks Center For Gifted Children, University Of Denver

Ricks Curriculum Units Series

An integrated curriculum is an instructional approach that connects the disciplines to an underlying theme or topic. Immersing students in an integrated-thematic unit provides the backdrop for experiences to occur across the disciplines. Shaping coursework around integrated themes is especially appropriate for gifted students, however using an integrated-thematic curriculum is appropriate for all learners as it develops students' abilities to make connections, to solve problems by looking at multiple perspectives, and to integrate information from different fields of experience. An integrated-thematic curriculum permits students to be active participants in their own learning as they design their own explorations and take …

Xml-Based Modeling And Simulation: Web Service Technologies And Their Synergy With Simulation, Senthilanand Chandrasekaran, Gregory S. Silver, John A. Miller, Jorge Cardoso, Amit P. Sheth

Kno.e.sis Publications

The World Wide Web has had an huge influence on the computing field in general as well as simulation in particular (e.g., Web-based simulation). A new wave of development based upon XML has started. Two of the most interesting aspects of this development are the Semantic Web and Web services. This paper examines the synergy between Web service technology and simulation. In one direction, Web service processes can be simulated for the purpose of correcting/improving the design. In the other direction, simulation models/components can be built out of Web services. Work on seamlessly using simulation as a part of Web …

Authorization And Access Control Of Application Data In Workflow Systems, Shengli Wu, Amit P. Sheth, John A. Miller, Zongwei Luo

Kno.e.sis Publications

Workflow Management Systems (WfMSs) are used to support the modeling and coordinated execution of business processes within an organization or across organizational boundaries. Although some research efforts have addressed requirements for authorization and access control for workflow systems, little attention has been paid to the requirements as they apply to application data accessed or managed by WfMSs. In this paper, we discuss key access control requirements for application data in workflow applications using examples from the healthcare domain, introduce a classification of application data used in workflow systems by analyzing their sources, and then propose a comprehensive data authorization and …
