Atmospheric Response To 1988 Drought Conditions And Future Climate Implications, Michael D. Mccorcle

Journal of the Iowa Academy of Science: JIAS

Plentiful precipitation in the central United States is one of the basic components of the successful agricultural industry in the Corn Belt. A combination of moisture, wind, and topographic factors creates an ideal condition for rainfall over most of the region during the late spring and early summer. In 1988, many ingredients necessary for wet weather were absent. The region experienced a drought unequalled since the 1930's. The drought of 1988 demonstrated chat the symptom of drought, namely, dry soils, can exacerbate and even perpetuate drought conditions by decreasing available moisture, altering circulation patterns vital to storm development, and increasing …

Bibliography Of The Natural And Cultural History Of The Loess Hills Of Iowa, Dean M. Roosa, Darwin D. Koenig

Journal of the Iowa Academy of Science: JIAS

A bibliography of literature on Iowa's Loess Hills includes references containing information on the cultural or natural history of chis western Iowa landform region. The bibliography is divided into six parts: general, archaeological, botanical, geological, historical, and zoological. Annotations are included only where necessary to clarify contents. Because of their rugged topography, the Loess Hills of western Iowa have resisted large-scale conversion to agriculture. This has permitted noteworthy persistence of native prairies and woodlands, along with their associated species. This bibliography complements two special issues of the Proceedings of the Iowa Academy of Science devoted to Iowa's Loess Hills.

Fisheries Development And Its Role For Alleviating Nutritional Deficiency In Mauritania, Dia Mamadou Abdoul

Marine Affairs Theses and Major Papers

Security of food supply is one of the greatest problems that Mauritania continues to face. Fisheries development, both artisanal and industrial, has the potential of providing an increased and reliable low-cost source of animal protein and it could also help to alleviate the problems of the agricultural sector. The main focus of this paper will be upon fisheries development in Mauritania and how it may contribute to alleviating malnutrition. The examination of Mauritania's fisheries policy, the significance of the political and economic context in which fishing policy was formulated, the effects that these different policies have on Mauritania's overall development …

Book Review: Fragile Giants: A Natural History Of The Loess Hills, Kenneth D. Carlander

Journal of the Iowa Academy of Science: JIAS

The Loess Hills, which are a special feature of the eastern bank of the Missouri River in Iowa and northern Missouri, have been cited by Dean Roosa, Iowa's State Ecologist, as a "world treasure and ... our best-kept secret." These Hills are mounds of finely ground soil, "glacial flour," deposited by dust storms after the glaciers receded 31 to 12 thousand years ago. Loess is rather widely distributed in Iowa, but the extensive deposits (often over 200 feet deep) on and against the eastern wall of the valley left a rolling, wave-like, terrain which on erosion leaves vertical banks of …

Population Estimates And Geographic Distribution Of The Yellow Mud Turtle (Kinosternon Flavescens) In Iowa, James L. Christiansen, Benny J. Gallaway, John W. Bickham

Journal of the Iowa Academy of Science: JIAS

The yellow mud turtle (Kinosternon flavescens) is an endangered species in Iowa known from six localities in the stare. The only large population is located on a private preserve on Big Sand Mound in Muscatine and Louisa Countries and is estimated to consist of 2,000 to 3,000 individuals. Following the removal of predators in 1979, density estimates have tripled as estimated by the Sequential Bayes Algorithm of mark-recapture data. Assuming the Big Sand Mound population was nor severely damaged by the drought of 1988, it is judged sufficiently large to serve as a source to enrich certain of Iowa's other …

The Cladocera Of Lake West Okoboji, Iowa - Revisited, Kenneth L. Lang

Journal of the Iowa Academy of Science: JIAS

Seven stations, established in 1968 to sample Cladocera, were sampled again, using the same methods, in 1988. Seven species, all of them in low abundance, are new records for Lake West Okoboji. In 1988, there was little difference 1) in the ranking of the stations relative to abundance of cladocerans, 2) the distribution and abundance of the species by habitat-type, 3) the seasonality of the predominant species in the specific habitats, 4) the temporal patterns of the number of species and total cladoceran abundance in the specific habitats, compared to 1968. On the average there were more species but lower …

Review Of Early Prehistoric Agriculture In The American Southwest, By W. H. Wills. Santa Fe, New Mexico: School Of American Research Press, 1988. 196 Pages., Alan J. Osborn

Department of Anthropology: Faculty Publications

Last paragraph:

Wills's book provides archeologists with an innovative account of why and how past hunter-gatherers initially expanded their food-getting activities to include the cultivation of domesticated crops. His study makes use of a variety of subjects including r- and K-selection, density-dependent responses, risk minimization, the forager-collector continuum, maize phenology, Holocene environments, technological change, stylistic variation, social boundaries, and mating networks. Wills also offers new information and reassessments of the archeological record at Bat, Tularosa, Cordova, and Cienega Creek caves in the Mogollon highlands. He approaches the archeological literature for the American Southwest with healthy skepticism. And he challenges many …

Anatomical Characterization Of Western Corn Rootworm Damage In Adventitious Roots Of Maize, Walter E. Riedell, Alice Y. Kim

Journal of the Iowa Academy of Science: JIAS

Corn rootworms are one of the most economically damaging insect pests of maize, yet little is known about the feeding behavior of the larvae. This study was conducted to determine which tissues of the adventitious roots of maize are damaged by western corn rootworm (Diabrotica virgifera virgifera LeConte) larval feeding. Root axes (10 cm long) were removed from the fifth node of greenhouse-grown maize plants. Root segments 2 cm long, excised 4 or 6 cm from the root tip, were infested with second or third stage larvae, respectively, (0, 1, 3, or 6 larvae per segment) for a period of …

Gene Transfer In Crop Improvement - An Introduction And Overview, Robert M. Goodman

Journal of the Iowa Academy of Science: JIAS

The application of recombinant DNA technology to plant breeding promises important applications in agriculture and advances in many plant science disciplines. Gene transfer at the molecular level can be routinely accomplished in an increasing number of plant species. For many of the world's important crops, new methods or refinements of proven methods will be needed and are being developed. Experience with gene regulation in transgenic plants is accumulating in many laboratories around the world. The action of any particular gene cannot be predicted precisely without reference to the genetic background in which it acts, but, qualitatively speaking, the cis-acting elements …

Engineering Proteinase Inihibitor Genes For Plant Defense Against Predators, Clarence A. Ryan, Thomas Moloshok, Gregory Pearce, Gynhueng An, Robert W. Thornburg, Gerald Hall, Russell Johnson, Edward E. Farmer, Curtis Palm

Journal of the Iowa Academy of Science: JIAS

Small proteinaceous inhibitors (Mr<20,000) of the digestive serine proteinases of animals and microorganisms are found as moderately abundant proteins in storage organs and leaves of many plant genera. The proteins are powerful inhibitors of the digestive enzymes of plant predators and therefore are considered to be part of the array of defensive chemicals of plants. Proteinase inhibitor genes show excellent promise, using DNA technology, to manipulate plant genomes to express these biologically active proteins in order to improve natural defense systems. Members of two unrelated families of serine proteinase inhibitors found in tomato and potato plants, called Inhibitor I (monomer Mr 8000) and Inhibitor II (monomer Mr 12,300), are under both environmental and developmental regulation in different tissues of the plants. Genes coding for wound-inducible Inhibitors I and II have been isolated from both tomato and potato genomes and characterized. Tobacco plants have been transformed with the chimeric genes containing wound-inducible promoters fused with the reporter gene, chloramphenicol acetyl transferase, to assess promoter function and signal transmission. Transacting factors that regulate their expression in response to wounding are also being identified and purified. Intact genes are being employed to transform agriculturally important crop plants to determine their potential usefulness to enhance defensive capabilities of plants against herbivores and pathogens.

Characteristics Of Channel Catfish Populations In Streams And Rivers Of Iowa With Varying Habitats, Vaughn L. Paragamian

Journal of the Iowa Academy of Science: JIAS

From 1983 co 1985, more than 1,000 channel catfish (Icatalurus punctatus) were sampled with rotenone from 50 streams and rivers in Iowa to assess differences in population densities, standing stocks, viral statistics, age and growth, and habitat use Catfish densities ranged from 5 fish/ha in sites on the South Skunk and Upper Iowa Rivers to more than 4,400 fish/ha at a site on the Thompson Fork of the Grand River. Standing stocks ranged from a low of 0.1 kg/ha on a site on the South Skunk River to a high of 467 kg/ha on the East Fork of the Des …

Climate Change And The Potential Impact On The Soil Resource, J. L. Hatfield

Journal of the Iowa Academy of Science: JIAS

Climatic change will lead to changes in the carbon dioxide C0_2, temperature, and precipitation. There have been many predictions of the effect of climatic change on plant growth but none on the soil parameters or water use. To fully understand the implications on soil management from climate change the expected changes in soil temperature, water use, and water and nutrient use efficiency need quantification.

Radon Measurements In Houses In Eastern And Central Iowa, C. V. Weiffenbach, T. J. Hart

Journal of the Iowa Academy of Science: JIAS

Radon concentrations in air in main floor areas of 213 houses in Central and Eastern Iowa were measured with alpha track detectors integrating over periods of five months to one year. Forty-two houses in Central Iowa had significantly higher radon concentrations (lognormal distribution with geometric mean 2.1 pCi/L, geometric standard deviation 2.2, and arithmetic mean 2.75 pCi/L) than 171 houses studied in Eastern Iowa (geometric mean 1.6 pCi/L, geometric standard deviation 2.2, arithmetic mean 2.1 pCi/L). Significant differences in radon levels were found among different categories of houses with regard to ventilation rate, basement construction, and cracks and openings in …

The Effect Of Harvesting On Macrophyte Regrowth And Water Quality In Ladue Reservoir, Ohio, G. Dennis Cooke, Angela B. Martin, Robert E. Carlson

Journal of the Iowa Academy of Science: JIAS

Two experiments in a bay of LaDue Reservoir (Geauga Co., northeastern Ohio) during summer, 1985 demonstrated that removal of Eurasian watermilfoil (Myriophyllum spicatum L.) root crowns with an aquatic weed harvester retarded plant regrowth to quantities well below nuisance levels for 28 days. Nearly summer-long control was achieved following a "touch-up" harvest on day 42. In contrast, the harvester was used in this bay in 1982 to "mow" milfoil, leaving intact "stumps." The mowed plants regrew to preharvest and control area biomass levels within 23 days. The difference in plant regrowth between these two methods strongly suggests that user dissatisfaction …

Plant Parasitic Fungi Of Four Tallgrass Prairies Of Northern Iowa: Distribution And Prevalence, Lois H. Tiffany, Judy F. Shearer, George Knaphus

Journal of the Iowa Academy of Science: JIAS

Throughout the 1980's, most intensively during the past five years, collections of fungal parasites of prairie plants have been made at various times of the growing season from four prairie preserves, Cayler, Freda Haffner Kettlehole, Hayden, and Stinson prairies, in northern Iowa. A total of 216 species of parasitic fungi were collected on 129 prairie plant hosts. Ninety-nine of the fungi were not previously documented from Iowa. Also, fungus species previously reported were found on 72 host species not included in earlier records.

Correlation Of Raccoon Pelt Qualities With Age, Sex, And Physical Condition, Travis C. Glenn

Journal of the Iowa Academy of Science: JIAS

Fur harvesters and fur buyers have many intuitive ideas about how raccoons' pelt qualities differ due to age, sex, or physical condition. We tried to demonstrate correlations between age classes (juvenile and adult), sex, and physical condition and the quality of raccoon pelts. Quality of pelts was described in three objective ways: size of the pelt, density of the pelage (primeness), and color of the pelage. Physical condition was measured by kidney fat index (KFI) and skin fat index (SFI). Size of the pelts was correlated with age, sex, and both measures of physical condition. Primeness of the pelts was …
