Tests Of A Rotenone-Impregnated Bait For Controlling Common Carp, Joseph L. Bonneau, Dennis L. Scarnecchia

Journal of the Iowa Academy of Science: JIAS

An experimental rotenone-impregnated pelleted (approximately 10 mg/pellet) bait was tested in force-feeding and field-feeding experiments as a method of control for common carp (Cyprinus carpio). Mortality rates of force-fed fish ranged from less than 40% when fed one pellet to 100% when fed more than 10 pellets. Mortality occurred within 48 h. Mortality rates of control fish did not exceed 10%. In reservoir feeding trials in 1994 and 1995, carp were fed for 2-3 weeks on a non-toxic, vegetable-based bait dispensed by automatic feeders, followed by one feeding of the bait with rotenone added. Carp ceased feeding on the rotenone …

Recent Observations Of The Distribution And Status Of Bluntnose Darters And Crystal Darters In Iowa, Melvin C. Bowler

Journal of the Iowa Academy of Science: JIAS

The distribution and status of Iowa's fishes were last extensively described in Iowa Fish and Fishing (Harlan et al. 1987). Since then, numerous fish collections have been made in Iowa's interior and bordering rivers and streams. Excluding non-native species, there have been three documented accounts of new fish species distributional records in Iowa since 1987. In this paper, I describe new collections of crystal darter (Crystallaria asprella) and bluntnose darter (Etheostoma chlorosomum) from the Mississippi River. The first documented specimen of C. asprella in Iowa was collected in Pool 11 of the Upper Mississippi River (UMR) in 1995. One specimen …

Tillage Effect On Soil Water Content And Soybean (Glycine Max) Yield In A Strip Intercropping System, M. Ghaffarzadeh, F. Garcia Prechac, M. M. Harbur, R. M. Cruse

Journal of the Iowa Academy of Science: JIAS

Soybean [Glycine max (L.) Merr.] response to strip-intercropping with corn (Zea may L.) and oat (Avena Jativa L.) interseeded with nondormant alfalfa (Medicago Jativa L.) may be affected by soil moisture. A three-crop strip-intercropping system of corn, soybean and oat interseeded with nondormant alfalfa was established to determine the effect of tillage system and row position on soil water content and grain yield in the soybean strip. The experiment was a split-plot design with three tillage treatments (conventional, CT; reduced, RT; and minimum tillage, MT) as main plot effects and three row positions (both edge rows and the center …

Identification And Distribution Of The Treefrogs Hyla Versicolor And Hyla Chrysoscelis In Iowa, Catherine E. C. Oberfoell, James L. Christiansen

Journal of the Iowa Academy of Science: JIAS

Historically, the tetraploid and diploid species pair of gray treefrogs, Hyla versicolor and Hyla chrysoscelis, were mapped collectively in Iowa because no macroscopic morphological characteristics useful in recognizing the two species had been found. The present study reports identification and separation of the species by counts of nucleoli in the palpebral membrane of the eye and by measurement of scanning electron micrographs of toepad epithelial projections. Subsequent morphometric data confirm that the two species are morphologically distinct in Iowa but that overlap in characters continues to make macroscopic morphology unreliable for identifying individuals. H. chrysoscelis is distributed sporadically though all …

Species Specific Odds Of Occurrence Of Blackspot Among Fish From The Maple River In Western Iowa, John W. Mellen

Journal of the Iowa Academy of Science: JIAS

Odds ratio analysis was used to evaluate the relative likelihood of occurrence of blackspot (Neascus pyriformil, Chandler) infections among 14 species of fish collected from the Maple River in Buena Vista and Ida Counties in western Iowa. Prevalence estimates ranged from 0% to 47.4% with a mean prevalence of 11.9%. The rank ordering of odds ratios of infection allowed the species to be categorized as those with risks greater than, less than, and not different from average risk to infection within the Maple River sample. The species with the largest odds ratio was the bluntnose minnow, (Pimephales notatus) (odds ratio …

Lessons From An Inventory Of The Ames, Iowa, Flora (1859-2000), William R. Norris, Deborah Q. Lewis, Mark P. Widrlechner, Jimmie D. Thompson, Richard O. Pope

Journal of the Iowa Academy of Science: JIAS

A botanical survey of the vascular flora of the "planning and zoning jurisdiction" of the city of Ames, Iowa (i.e., the area within a boundary 3.2 km beyond the current city limits) was compiled from 1990 to 2000. During this survey, 916 taxa (71 % native) were encountered within chis boundary. Literature reviews and a survey of Iowa State University's Ada Hayden Herbarium for specimens that had been collected in Ames since 1859 add 204 taxa to the flora. This total of 1,120 taxa exceeds the number of taxa known from any comparable area (including counties) in Iowa. We produced …

Myxomycetes Of Big Bend National Park, Texas, Lois H. Tiffany, George Knaphus

Journal of the Iowa Academy of Science: JIAS

Seventy species of Myxomycetes have been collected directly in the field or observed later in the laboratory from field materials in moist chambers from Big Bend National Park, Texas. Collections were made over a 10 year period, 1989-1997 and 1999, during intensive seven-day fungus collecting trips to Big Bend in late September each year. McGraw (1968) in an earlier study of Texas Myxomycetes had reported 28 species from Big Bend, some of which were also found in this study. A total of 81 species are reported from the park. A variety of environmental conditions occurred during the 10 years with …

Literature-Based Language Arts Extended To Science, Jennifer A. Johnson

Graduate Research Papers

A literature-based language arts program provides meaningful experiences for children within the functions of language. Such programs can be extended across the curriculum to utilize the functions in other areas. These connections across the curriculum can be enhanced through the different genres of literature.

In this article, a literature base was integrated into the science area of the curriculum. A science unit on pumpkins was developed for first grade children with quality literature and related expressive activities that extended the children's literacy and their understanding of plants. Teacher-directed activities were presented along with learning centers.

Examining The Need For Improved Health Education For Underserved Populations In Selected Eastern Caribbean Basin Nations, Linda K. George Miller

Graduate Research Papers

The Eastern Caribbean Basin (ECB) is comprised of several diverse islands that share many common characteristics. As tourism has increased in most of the islands, chronic disease patterns have also increased. The governments of these island nations are well aware of the need for increased health education efforts, but adequate personnel are not always available locally.

Complications from chronic disease are escalating in the aging population. Efforts to expand health education efforts among the islands would assist in reducing these complications and early deaths.

Diseases often seen on the ECB islands include hypertension, cardiovascular and heart disease, diabetes, cancer, and …

The Effect Of Valproic Acid On Motility And Morphometry Parameters, And Actin And N-Cadherin Distribution In Avian Neural Crest Cells, Leah Christine Fuller

Dissertations and Theses @ UNI

All vertebrate species contain a transient ectodermal structure termed the neural crest from which a specific subpopulation of migratory cells, the neural crest cells (NCCs), is derived. Following an epithelial-mesenchymal transition, NCCs actively migrate throughout the developing embryo. Precise temporal and spatial cellular migration is essential for the formation of a diverse array of neural crest derived tissues and structures. Valproic acid (VP A) is a unique anti-convulsant drug that can produce craniofacial and neural tube defects in exposed infants. Alterations of NCC migration, proliferation, and cytoskeletal composition have been proposed as mechanisms of VP A's teratogenicity. To investigate this …

Developmental Tendril Morphology In Echinocystis Lobata (Michaux) Torrey And Gray (Cucurbitaceae), Theodore Bowen Guthrie

Dissertations and Theses @ UNI

Tendrils are generally defined as coiling organs used as mechanical supports and for climbing. The morphological nature of the tendril and the branching pattern of the axillary bud complex (ABC) in the family Cucurbitaceae have been the subject of investigation for over a hundred years and as of yet there is no unifying interpretation of their morphological values. The tendril in the Cucurbitaceae has been hypothesized to be homologous to a leaf, a flower, a stem, and a combination of stem and leaf. Echinocystis lobata (Michaux) Torrey and Gray was used as a model to study the ontogeny of the …
