Plant Parasitic Fungi Of Ten Tallgrass Prairies Of Iowa: Distribution And Prevalence, Lois H. Tiffany, George Knaphus

Journal of the Iowa Academy of Science: JIAS

During the 1980s and 1990s, collections of fungal parasites on above ground parts of prairie plants in Iowa were made throughout the growing seasons. This report presents the fungi recorded from three groups of Iowa tallgrass prairies. The western group was composed of Dinesen, Steele and Stinson Prairie State Preserves, a Loess Hills group of collecting sites in Five Ridge and Runkel Prairie State Preserves and prairies at Waubonsie State Park. 180 species of fungi were collected on 116 hosts from these prairies. A central Iowa group of prairies associated with the Des Moines Lobe landform, Anderson, Doolittle, Kalsow and …

A Comparison Of Drinking Water Contamination In Buried Slab Wells, Other Large-Diameter Wells, And Drilled Wells, Rita M. Gergely

Journal of the Iowa Academy of Science: JIAS

This study presents the results of a statewide water well survey conducted by the Iowa Department of Public Health from 1993 to 1995 to determine whether there were statistically significant differences between well water contamination in buried slab wells, other large-diameter wells, and drilled wells. Wells were sampled for total coliform bacteria, fecal coliform bacteria, nitrate, and atrazine. Staff collected water samples and completed a site survey at each well, which included an interview with the occupant or owner and actual observations of the wellhead and surrounding area.

The study included 293 buried slab wells, 287 other large-diameter wells, and …

Biomass Yield Stability In Alfalfa, Joseph G. Robins, Heathcliffe Riday, Sara J. Helland, E. Charles Brummer

Journal of the Iowa Academy of Science: JIAS

In addition to biomass production, alfalfa (Medicago sativa) cultivars also need to express yield stability across diverse environments. The objective of this experiment was to analyze the nature of biomass yield stability in ten commercial alfalfa cultivars by evaluating performance of individual genotypes. Biomass yield was measured in each of five environments across two years, and the yield stability computed for the overall cultivar mean performance and the mean performance of each of the genotypes comprising the cultivars using the genotype x environment variance statistic of Shukla and the superiority statistic of Lin and Binns'. The GxE variance of the …

The Freshwater Mussels (Mollusca: Bivalvia: Unionidae) Of The Boone River, North Central Iowa, Ellet Hoke

Journal of the Iowa Academy of Science: JIAS

A survey of the freshwater mussels of the Boone River conducted in September 1982 documented a fauna consisting of seventeen then extant or relict species. Analysis of museum records yielded one additional species unrecovered since 1937. Subsequent to the 1982 study, additional surveys were conducted in the region in 1984-1985 and 1998-1999 as a part of two statewide surveys. A comparison of the results of the three studies suggests a significant decline in the unionid fauna in the Boone River since 1982. While it is almost certain that a real decline in the fauna has occurred, the extent of this …

The Impact Of White Pine (Pinus Strobus) On A Mollisol After Seven Decades Of Soil Development, Irina Kovda, Eric C. Brevik, Thomas E. Fenton, Maria Gerasimova

Journal of the Iowa Academy of Science: JIAS

Selected chemical, physical, and macro and micromorphological properties in two pedons of a Clarion soil (Fine-loamy, mixed, superactive, mesic Typic Hapludolls) formed in till parent material, one planted to white pines (Pinus strobus) for the past 75 years and the other to grass, were compared. The most obvious difference between the two was the increased biological activity under pines; the variety and quantity of excrements suggested the activity of soil microfauna and variability of species resulted in finer and better aggregation of biological origin (crumbs and granules), numerous excrements in voids, and higher total porosity under pines. The matrix was …

Flow Cytometry Used To Assess Genetic Damage In Frogs From Farm Ponds, Bartholomew L. Bly, Melinda G. Knutson, Mark B. Sandheinrich, Brian R. Gray, Dean A. Jobe

Journal of the Iowa Academy of Science: JIAS

Flow cytometry (FC) is a laboratory method used to detect genetic damage induced by environmental contaminants and other stressors in animals, including amphibians. We tested FC methods on three species of ranid frogs collected from farm ponds and natural wetlands in southeastern Minnesota. We compared FC metrics for Rana clamitans between ponds with direct exposure to agricultural contaminants and reference (unexposed) ponds. Concentrations of atrazine in water from our farm ponds ranged from 0.04 to 0.55 ppb. We found that R. clamitans from exposed ponds had DNA content similar to frogs from unexposed ponds. Pond-averaged C-values (a measure of DNA …

Early Childhood Thematic Unit: A 32-Week Curricular Resource: Fairy Tales - Insects - Dinosaurs, 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 …

Occurrence Of Ovotestes And Plasma Vitellogenin In Feral Male Fathead Minnows From Lagoons Of Municipal Wastewater Treatment Facilities In Central Iowa, Robert B. Bringolf, Robert C. Summerfelt

Journal of the Iowa Academy of Science: JIAS

Since the early 1990s, endocrine disrupting compounds have been recognized as an important environmental threat. Male fish exposed to effluent from large, metropolitan municipal wastewater treatment facilities (WWTFs) have developed reproductive abnormalities including ovotestes and elevated levels of plasma vitellogenin (Vtg), a plasma protein typically produced by egg-laying females. In the summer of 2000, gonads and plasma Vtg concentrations were examined in feral male fathead minnows (Pimephales promelas) collected from lagoons of 11 small, rural municipal WWTFs and a reference site (a national wildlife refuge) in Iowa. Fathead minnows were captured in traps from five of the 33 lagoons (three …

Cathodoluminescence As A Means For Distinguishing Hydrothermal From Pre-Hydrothermal Quartz In Sulfide-Bearing Mineral Deposits On The Northern Fringe Of The Upper Mississippi Valley Zinc-Lead District, Ne Iowa And Sw Wisconsin, Paul L. Garvin

Journal of the Iowa Academy of Science: JIAS

Sulfide-bearing mineral deposits, located on the northern fringe of the Upper Mississippi Valley Zinc-Lead District, are contained in early Ordovician carbonate rocks that are extensively silicified and dolomitized. Some silica and dolomite appear to be products of the hydrothermal processes that also formed fracture-filling and cavity-lining sulfides and other cogenetic minerals; other silica and dolomite appear to result from low-temperature, pre-hydrothermal regional diagenesis. Distinguishing hydrothermal quartz (jasperoid) from pre-hydrothermal quartz (chert) solely by hand specimen and thin section petrography is difficult because these two types of mineralization are often intimately associated with each other. Polished slabs from several of these …

Salt Tolerance Of Sunflower And Lettuce In Cultivated And Uncultivated Grass Soil, Steven H. Emerman, Emily M. Kinsinger

Journal of the Iowa Academy of Science: JIAS

We tested two hypotheses: 1) whether a vegetable crop will show greater growth under a given salinity treatment in an uncultivated grass soil than a cultivated soil and 2), if so, whether the greater growth is due to the occasional presence of relatively fresh water in macropores or the interaction between salinity and hypoxia in a soil without significant macropores. A previous study suggested uptake from. macropores was significant only for crops with high root water potential (Emerman and Dawson 1997). Hence, in this study, 21 miniature crops were grown in a greenhouse, and the ratio of root dry weight …

A Key To The Eggs And Nests Of Iowa Turtles, James L. Christiansen, Jeffrey R. Parmelee

Journal of the Iowa Academy of Science: JIAS

Biologists often need to identify destroyed turtle nests where a predator has excavated and eaten the eggs. We present a dichotomous key to the eggs and nests of Iowa's turtles based on egg or nest morphology and known range of the species. Egg and nest morphology clearly separated most nests of the families Chelydridae and Kinosternidae and many of the Emydidae. However, egg morphology must be combined with known range to distinguish wood turtles (Glyptemys insculpta) from other emydids. These factors will also separate most false map turtles (Graptemys pseudogeographica) from other species. Similarities among egg morphologies, nest morphologies, and …

Submersed Aquatic Vegetation Trends In Impounded And Backwater Habitat Types Of Pool 13, Upper Mississippi River System: 1994-2000, Theresa A. Blackburn, Daniel J. Kirby

Journal of the Iowa Academy of Science: JIAS

Submersed aquatic vegetation (SAV) was sampled from 1994-2000 at fixed sires along established transects in Pool 13 of the Upper Mississippi River System (UMRS), as part of the Long Term Resource Monitoring Program (LTRMP). These data were used to quantify the annual percent frequency of occurrence and mean relative density of SAV within three backwaters (Brown's Lake, Savanna Bay, and Spring Lake) and the impounded area of Pool 13. This investigation used Spearman rank correlation to assess the strength of bivariate relationships between measurements of SAV abundance and biological, physical, and hydrological variables at fixed water quality monitoring sites within …

An Assessment Of Water Quality In Ensign Hollow, Clayton And Fayette Counties, In Northeast Iowa, Rick Klann, Jaime Platts

Journal of the Iowa Academy of Science: JIAS

Water quality and benthic invertebrates in the Ensign Hollow watershed, southwestern Clayton County and southeastern Fayette County, Iowa, were monitored from 2000 to 2001. Measurements of physical and chemical parameters of water quality, as well as analysis of benthic invertebrates, all indicated that streams of the Ensign Hollow watershed were exposed to slight organic pollution. Furthermore, the greatest threat to this watershed appeared to be sedimentation introduced through runoff.
