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 …

The Athlete As Trickster, Gerald Gems

Ethnic Studies Review

This study invokes hegemony theory to analyze the role and uses of sport as a means to resist dominant group pressures and the adaptation of sporting practices to subordinate groups' needs. The study draws upon literary and anthropological works that support the role of the trickster as a resistive, even manipulative figure, who fulfills both instructive and psychological needs for particular subordinate groups.

Return To Neighborhood Schools, Concentrated Poverty, And Educational Opportunity: An Agenda For Reform, Patrick James Mcquillan, Kerry Suzanne Englert

UC Law Constitutional Quarterly

Throughout the US, school systems that once faced federally-mandated desegregation plans have been declared "unitary" - that is, courts ruled that these districts have removed any vestiges of overt segregation and therefore need not adhere to previous integration mandates. In Denver, Colorado, after busing students for over 20 years, federal courts declared the city school system unitary in 1996. In Denver the return to neighborhood schools has meant a concurrent return to more racially segregated schools. Given the strong correlation between race/ethnicity and socioeconomic status in US urban centers, the return to neighborhood schools has created conditions of concentrated poverty …

A Linguistic And Anthropological Survey Of The Tibetan Borderland, Krisadawan Hongladarom

Asian Review

This paper reports the linguistic and anthropological situation of an important but poorly documented region of Tibet, namely the cultural province of Kham. Characterized by "four rivers and six ranges, " the region n a historical frontier zone between Tibet proper and western provinces of China n has been a meeting place between the Tibetans and the Han Chinese and a common home for these peoples as well as other ethnic minorities. As an introduction to the ethnic and linguistic complexity of Kham, the paper pays a special attention to Gyalthang (Zhongdian), which is located on the southernmost tip of …

Low-Saturated-Fat Soybean Oil Reduces Saturated Fat In School Menus, J. M. Mahnken, S. F. Lutz, C. J. Anders, W. R. Fehr

Journal of the Iowa Academy of Science: JIAS

This study evaluated the impact of using low-saturated-fat soybean {Glycine max (L.) Merr.} oil on the saturated fat content of school menus. Seventy-six weekly menus were obtained from the Iowa Department of Education during School Meals Initiative reviews for the 1996-1997 school year. Three modifications were performed on school menus using the Nuttikids computer program: Low-saturated- fat (LSF) soybean oil replaced traditional vegetable oil in menu items; LSF soybean oil was substituted for traditional vegetable oil, solid fats, and egg yolks in recipes; and a menu simulation was conducted where oils and solid fats used in menu items were …

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 …

Expression Of Heterosis In Leaming And Midland Corn Belt Dent Populations, M. J. Carena, A. R. Hallauer

Journal of the Iowa Academy of Science: JIAS

Successful maize (Zea mays 1.) breeding programs are based on specific heterotic patterns. The Iowa Stiff Stalk Synthetic x Lancaster Sure Crop heterotic pattern is widely exploited in U.S. maize breeding programs. Alternative U.S. heterotic patterns have been suggested, but they have received limited attention and improvement. The objectives of this study were to evaluate cultivar crosses between Leaming and Midland Yellow Dent cultivars before and after inbred progeny selection and to assess their potential as an alternative U.S. heterotic pattern. Grain yield had a midparent heterosis value of 4.9% before selection and 17.8% in the third cycle of selection. …

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 …
