Iowa Prairie: Original Extent And Loss, Preservation And Recovery Attempts, Daryl D. Smith

Journal of the Iowa Academy of Science: JIAS

Iowa's prairie has to be assessed in the context of the pre- and post-agriculturally dominated ecosystem in which it now exists. This requires an understanding of prairies and of society's perspective of prairies. Therefore, the attitudes of people through time have to be considered; (1) those who were involved in the demise of the prairie, (2) those who helped saved the pieces of the prairie and (3) those who may be called upon to recover the prairie ecosystem.

The Expectations And Perceptions Of Incoming Freshmen At Uni, Kristin Michael

Presidential Scholars Theses (1990 – 2006)

As colleges and universities have become increasingly competitive in their recruitment and retention of students, they have placed greater emphasis on the quality of the freshman experience. The nature of this experience serves as the focus of this study. This paper draws upon qualitative data about the perceptions and expectations of students beginning their first year of enrollment at the University of Northern Iowa. In doing so, it examines students' expectations and perceptions regarding their (1) prospective academic workload, (2) relationships with faculty, (3) relationships with peers, and ( 4) co-curricular involvements. While this study examines only the University of …

Relationship Between Television Viewing And Physical Activity Levels Among College Students, Sarah Joan Brummer

Dissertations and Theses @ UNI

The purpose of this study was to examine the relationship between leisure time physical activity levels and time spent viewing television (including video or computer game play) among college students. Sub-problems included the physical activity profiles of males compared to females and the association between self-reported intensity of physical activity and time spent viewing television. The present study utilized a nonexperimental research design. Specifically, survey methodology using a self-report questionnaire was used as the means of data collection. The self-report questionnaire was designed to measure demographic characteristics, leisure time television viewing, and physical activity behaviors. A total of 789 students …

Forest Research In Iowa's State Parks - The Values Of Natural Diversity, Donald R. Farrar

Journal of the Iowa Academy of Science: JIAS

Approximately 3% of Iowa's forests are contained in state parks and preserves. In addition to aesthetics and recreation, these protected forests provide a vital service in the unique opportunities they provide for forest research. As intact ecosystems where natural ecological processes dominate, they provide standards by which we measure the effects of livestock pasturing, methods of timber harvest, and other manipulations of managed forests. A number of current studies and public programs emphasize the importance of natural diversity in forests. They rely on state parks and preserves to provide a measure of potential diversity for a given region of the …

Fungal Colonization Of Alfalfa Stubble Following Harvest, J. K. O'Mara, G. P. Munkvold

Journal of the Iowa Academy of Science: JIAS

Two-year-old stands of alfalfa cultivars Saranac and Vernal, planted in Central Iowa, were sampled 0, 15, and 30 days after the first harvest in 1995 to identify fungi colonizing the stubble left after harvest and evaluate the role of harvest-induced wounds as infection sites for potential crown-rotting fungi. Analysis of variance was conducted to determine if sampling date and cultivar significantly affected incidence of the fungi. All stems were infected with at least one fungal species at every sampling dare. The fungal genera most frequently isolated were Alternaria, Colletotrichum, Fusarium, Phoma, and Rhizoctonia. Fusarium acuminatum was the most frequently isolated …

Distribution And Abundance Of Prairie Plant Species In The Loess Hills, Thomas R. Rosburg

Journal of the Iowa Academy of Science: JIAS

The species composition of grassland and ecotonal communities throughout the Loess Hills was studies between 1990 and 1993. Information pertaining to the latitudinal distribution of species in the Loess Hills, the abundance of species among community types (i.e., habitats), species persistence under woody encroachment, species associations, and resource partitioning among species is provided for the majority of grassland species occurring in the Loess Hills. The most abundant species on extant prairie in the Loess Hills include Bouteloua curtipendula (side-oats grama), Schizachyrium scoparium (little bluestem), Andropogon gerardii (big bluestem), Cornus drummondii (rough-leaved dogwood), Aster ericoides (heath aster), Carex heliophila (sun-loving sedge), …

Book Review - Okoboji Wetlands. A Lesson In Natural History, Robert W. Black

Journal of the Iowa Academy of Science: JIAS

Michael Lannoo's reverent, musing history of the Okoboji region, and especially its wetlands and the Iowa Lakeside Laboratory, is a uniquely structured, well-written and wonderfully illustrated introduction to a distinct region in Iowa, a rich natural history of wetland organisms and a relatively unexplored branch of environmental ethics. Lannoo draws upon many years of experience in this region, as a student, researcher and teacher, and the wonderful resources of the Iowa Lakeside Laboratory and the Iowa Great Lakes Maritime Museum to produce a volume that educates the reader of the history and natural history of the Okoboji region and provokes …

Research Note: Records Of Thirteen Ground Beetles (Coleoptera: Carabidae) New To Iowa, Foster Forbes Purrington, Kirk Jon Larsen

Journal of the Iowa Academy of Science: JIAS

A long-term ecological research initiative in northeast Iowa tallgrass prairies to evaluate the effects of prescribed burning on prairie insects was begun in 1993. During the course of this work we discovered 13 ground beetle species (Coleoptera: Carabidae) (Table 1) not previously reported from Iowa (Bousquet and Larochelle 1993).

Richard W. Pohl: Distinguished Botanist, Marjorie Conley Pohl

Journal of the Iowa Academy of Science: JIAS

In her biographical portrait of Dr. Richard W. Pohl, Mrs. Pohl provides an engaging personal perspective of her late husband, his development as a botanist, his career, and his family life. We gain a sense of Dr. Pohl as a dedicated scientist as well as a humanist. Although Dr. Pohl possessed an abiding curiosity regarding all things natural, he is best known and remembered for his focus on grasses. As Mrs. Pohl documents, this interest in grasses began in the late 1930's and continued throughout his life-ultimately he was regarded as an authority on grass taxonomy both nationally and internationally. …

Carnivorous Spadefoot (Spea Bombifrons Cope) Tadpoles And Fairy Shrimp In Western Iowa, Eugenia S. Farrar, Jane D. Hey

Journal of the Iowa Academy of Science: JIAS

Amphibian larval polymorphisms, rarely found in the Midwest, are more common in arid western regions. We have discovered that Plains spadefoot toad, Spea bombifrons Cope, tadpoles occur as carnivorous and omnivorous morphological forms in flooded soybean and corn fields on the Missouri River flood plain of western Iowa. Carnivores have longer snouts, larger beaks with an upper cusp and lower notch, shorter intestines with fewer loops than the omnivores, and they feed on fairy shrimp. A similar polymorphism in Spea multiplicata Cope enhances survival in the desert because the carnivore develops faster after consuming fairy shrimp and is able to …

Iowa's State Parks: A Various Language, Rebecca Conard

Journal of the Iowa Academy of Science: JIAS

Iowa's state park system is distinctive because academically based natural scientists were instrumental in drafting the 1917 State Park Law, in shaping the initial policies, and in establishing the first parks. The mandate of the 1917 law was broad, but its original intent was to preserve and conserve natural resources; providing recreational enjoyment was secondary. Between 1920 and mid-century the founding vision was recast time and again by compromises that sprang from economic necessity, competing interests, and changing societal values. The ideal of resource protection has remained a guiding principle, however, in large part because strong personalities provided continuity of …
