A Gravity Investigation Of The Fayette Structural Zone And Surrounding Area, Northeast Iowa, Richard L. Kellogg, Christopher Meinen
A Gravity Investigation Of The Fayette Structural Zone And Surrounding Area, Northeast Iowa, Richard L. Kellogg, Christopher Meinen
Journal of the Iowa Academy of Science: JIAS
A gravity survey was conducted over approximately 2600 square kilometers of northeast Iowa. The survey was undertaken to provide detailed gravity coverage at approximately one mile intervals and to investigate the sources of gravity anomalies in the study area. An additional objective was to verify with gravity data the presence of the Fayette Structural Zone, previously identified on the basis of magnetic linears. Four hundred and twenty-seven gravity stations were occupied and data from these stations combined with extant data from the Geological Survey Bureau of the Iowa Department of Natural Resources to produce the gravity interpretation. A Bouger gravity …
Habitat And Distribution Of Plants Special To Iowa's Driftless Area, William P. Pusateri, Dean M. Roosa, Donald R. Farrar
Habitat And Distribution Of Plants Special To Iowa's Driftless Area, William P. Pusateri, Dean M. Roosa, Donald R. Farrar
Journal of the Iowa Academy of Science: JIAS
A portion of the Upper Midwest escaped glaciation during the two most recent glacial epochs. This "Driftless Area", also known in Iowa as the "Paleozoic Plateau", comprises some 39,000 square kilometers (15,000 square miles) in the states of Illinois, Iowa, Minnesota, and Wisconsin. Today the highly dissected terrain provides a variety of habitats supporting a rich and diverse flora including many plants special to the area, i.e., principally, in Iowa, restricted to the Driftless Area. These special plants have received much attention, often having been discussed as possible relicts from past floras. However, distribution data for these species beyond the …
Well-Water Quality Data From A Volunteer Sampling Program: Audubon County, Iowa, L. S. Seigley, G. R. Hallberg, P. R. Walther, G. A. Miller
Well-Water Quality Data From A Volunteer Sampling Program: Audubon County, Iowa, L. S. Seigley, G. R. Hallberg, P. R. Walther, G. A. Miller
Journal of the Iowa Academy of Science: JIAS
This study presents the results of a countywide volunteer sampling of private well-water. Volunteers collected 231 well-water samples in Audubon County for nitrate-nitrogen (NO3,-N) and total coliform bacteria analyses during September 1988. Questionnaires were completed at all sites to document well construction, age and depth of well, well placement relative to septic system, barnyard/feedlots, location of chemical mixing/tank rinsing, and presence of abandoned wells.
Annual Report Of The Iowa Academy Of Science, 1992-93, Paul E. Rider
Annual Report Of The Iowa Academy Of Science, 1992-93, Paul E. Rider
Journal of the Iowa Academy of Science: JIAS
Starting in 1976, annual reports have served as a continuing record of the activities of the Iowa Academy of Science. These augment a 100 year history of the Academy which was written in the centennial year of 1975. This report covers the period from July 1, 1992 to June 30, 1993. It is based on the official records of the Academy (committee reports, Board minutes, correspondence) as well as the recollections, impressions and thoughts of the author.

Range Expansion Of The Great-Tailed Grackle In The 1900s, James J. Dinsmore, Stephen J. Dinsmore
Range Expansion Of The Great-Tailed Grackle In The 1900s, James J. Dinsmore, Stephen J. Dinsmore
Journal of the Iowa Academy of Science: JIAS
In 1900, the range of the Great-tailed Grackle extended north of the Mexican border only into Texas. Since then, it has expanded its range greatly. It now nests in 14 states and has strayed to an additional eight states and three Canadian provinces. Much of this expansion has occurred since 1960. Great-tails often stray far from their normal range, especially in spring. Most of these strays are single individuals. In states where they have nested, breeding birds typically reach the state a few years after the first reports of the species. Great-tailed Grackles do well in a variety of human …

Advances In Biomolecule Analysis: Ftms Of Macromolecules, Curtiss D. Hanson, Ira M. Simet, Suzanne R. Smith
Journal of the Iowa Academy of Science: JIAS
The development of Fourier transform ion cyclotron resonance (FT-ICR) as an analytical technique has opened new avenues to the analysis of high molecular weight biomolecules. Because mass analysis is based on a detection of a frequency, it is possible to obtain high resolution mass measurements without sacrificing sensitivity. The unique ability to analyze high mass ions is based in the design of a passive ExB ion trap. Although in the past, field inhomogeneities have limited this technique, recent developments in both trap designs and excitation techniques have resulted in major improvements in both sensitivity and resolution.
Mutant Weeds Of Iowa: V. S-Triazine Resistant Setaria Faberi Herrm, R. Thornhill, J. Dekker
Mutant Weeds Of Iowa: V. S-Triazine Resistant Setaria Faberi Herrm, R. Thornhill, J. Dekker
Journal of the Iowa Academy of Science: JIAS
S-triazine resistance in giant foxtail (Setaria faberi Herrm.) has been reported previously, but not in the midwestern U.S. corn belt or Iowa. A study was conducted using a chlorophyll fluorescence assay to confirm the presence of resistance in one S. faberi population in Iowa. Variable chlorophyll fluorescence assays confirmed that a population of this species with this type of resistance exists in Iowa. This is the first report of s-triazine resistance in S. faberi, and the fourth species with this type of herbicide resistance, found in an Iowa agroecosystem.
Community Dynamics Of Phytoplankton In A Typical Navigation Pool In The Upper Mississippi River, Theodore R. Lange, Ronald G. Rada
Community Dynamics Of Phytoplankton In A Typical Navigation Pool In The Upper Mississippi River, Theodore R. Lange, Ronald G. Rada
Journal of the Iowa Academy of Science: JIAS
In 1986 we studied phytoplankton in the mid-reaches of Pool 8, which is a typical navigation pool of the Upper Mississippi River. During years of normal discharge, the areas studied usually become distinctly different from each other (ranging from free-flowing river to stagnant marsh) as the ice-free season progresses. These differences among sites did not occur during our study because the discharge into Pool 8 during 1986 was about 85% greater than the 10-yr mean discharge (1972-1982). Moreover, differences among areas were not observed with respect to physical and chemical characteristics such as photic zone depth, temperature, dissolved nitrogen and …

The Pleistocene Glacial Record At Two Quarries In Decatur County, Iowa, Keith E. Schilling, Robert A. Stewart
The Pleistocene Glacial Record At Two Quarries In Decatur County, Iowa, Keith E. Schilling, Robert A. Stewart
Journal of the Iowa Academy of Science: JIAS
The Pleistocene stratigraphy and sedimentology of two quarry exposures near Grand River and Decatur City in Decatur County, Iowa document a sequence of Pleistocene sediments overlying striated Pennsylvanian limestone which represent at least two pre-Illinoian glacial advances into the ancestral Grand River valley. Two pre-Illinoian diarnictons separated by a clast pavement were observed at the Decatur City quarry; a single diarnicton was present at the Grand River quarry. At both quarries, the diarnictons exhibit comparable lithologic properties and are genetically interpreted as basal tills. The pre-Illinoian tills are tentatively correlated with the Alburnett Formation in eastern Iowa, primarily on the …
Mass Selection For Adaptation In Antigua Maize (Zea Mays L.) Composite, F. M. San Vicente, A. R. Hallauer
Mass Selection For Adaptation In Antigua Maize (Zea Mays L.) Composite, F. M. San Vicente, A. R. Hallauer
Journal of the Iowa Academy of Science: JIAS
Tropical maize (Zea mays L.) germplasm has had limited use in temperate areas because of photoperiod sensitivity. Antigua germplasm from the island Antigua was introduced co Iowa because of its resistance to important pests of maize and its heterosis exposed m crosses with ocher tropical varieties. Mass selection procedures were used to adapt the Antigua Composite germplasm co Iowa conditions. After. Six cycles of mass selection for earlier silk emergence, the selected Antigua Composite flowered 17 days earlier than the original composite. Grain yield and ocher agronomic traits of the adapted scram of Antigua were similar co chose of adapted …
