The Distribution Of Amphipods In Southeastern Minnesota And Their Relation To Water Quality And Land Use, James A. Muck, Raymond M. Newman Jan 1992

The Distribution Of Amphipods In Southeastern Minnesota And Their Relation To Water Quality And Land Use, James A. Muck, Raymond M. Newman

Journal of the Iowa Academy of Science: JIAS

The distribution of the amphipods Gammarus pseudolimnaeus and Hyalella azteca was determined from 97 designated trout streams in Minnesota, along with temperature, conductivity, and nitrate levels. Streams were classified into 4 land use/geology groups. G. pseudolimnaeus was found in 11 counties and at 123 of 168 sites in 83 of the 97 streams sampled. Hyalella azteca was found in 7 counties at 26 sites m 21 streams. Spearman rank correlations showed a high degree of correlation between nitrate (range: 0-11 mg N/L), conductivity (range: 325-870 μS/cm), and geology. The relative abundance of G. pseudolimnaeus was negatively correlated with nitrate, geology …


Geology Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii, R. G. Baker Jan 1992

Geology Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii, R. G. Baker

Journal of the Iowa Academy of Science: JIAS

Fens are peatlands which are dependent on groundwater discharge to provide nutrient enrichment. Fens are found in a variety of landscape positions and in most Iowa landform regions. This paper presents a classification system for Iowa fens based on landscape position, stratigraphy, and hydrologic factors. Iowa fens can be separated into six categories: 1) fens along valley wall slopes; the groundwater source for these fens is sand and gravel buried between glacial tills (inter-till); 2) fens in hummocky topography on the northwestern margin of the Des Moines Lobe landform region; the water source is sand and gravel buried within glacial …


The University Of Iowa Museum Of Natural History: An Historical Perspective, George D. Shrimper Jan 1992

The University Of Iowa Museum Of Natural History: An Historical Perspective, George D. Shrimper

Journal of the Iowa Academy of Science: JIAS

The 132-year record of UIMNH essentially mirrors historical and on-going trends in related institutions. As scholarship grew in the natural sciences during the 19th century, natural history museums became centers for scientific research. A "Golden Age" of museum-based expeditionary work and taxonomic research was marked at UI by the careers of curator/naturalists Calvin, Nutting, Macbride, and Shimek. Systematic biology and paleontology thrived with the accumulation of extensive collections. De-emphasis of "natural history" studies followed after 1920-30 with a concomitant growth in cellular and molecular biology. In seeking new directions and financial support, many museums, including UIMNH, shifted emphasis to public …

Necklace Radio Transmitter Attachment For Pheasants, Terry Z. Riley, Bruce A. Fistler Jan 1992

Necklace Radio Transmitter Attachment For Pheasants, Terry Z. Riley, Bruce A. Fistler

Journal of the Iowa Academy of Science: JIAS

We tested a pre-assembled, necklace-radio-transmitter-attachment design on female ring-necked pheasants (Phasianus colchicus) in northern Iowa. Birds were captured by nightlighting and bait trapping between September 1989 and March 1990. Radio transmitters were attached to 128 using a wire necklace. Two birds had problems adapting to the necklace, and 3 birds removed them. Twenty-three birds were still alive and wearing necklaces at the end of the study, for an average of 318 (SD= ± 52) days. Ease of attachment, long durability, light weight, and minimal bulk make the necklace an effective alternative to harness and poncho mounts.


Book Review: Landforms Of Iowa, Michael L. Thompson Jan 1992

Book Review: Landforms Of Iowa, Michael L. Thompson

Journal of the Iowa Academy of Science: JIAS

Many of us are interested in the landscape around us. We ask: Why is this hill so steep or why is that valley so wide? Why does my garden's soil have so much clay? Why does Iowa have no mountains' Landforms of Iowa should capture a broad audience of teachers, students, agriculturalists of all sorts, historians, homemakers, naturalists, botanists, biologists, foresters, geographers, civil engineers, as well as geologists and pedologists-in short, just about any Iowan who has ever wondered how and when the landscape at his or her doorstep or outside the car window was fashioned. Its stated purposes are …

Fifty Years Of Fisheries Management M An Obstinate Prairie Lake, Dennis L. Scarnecchia, James R. Wahl Jan 1992

Fifty Years Of Fisheries Management M An Obstinate Prairie Lake, Dennis L. Scarnecchia, James R. Wahl

Journal of the Iowa Academy of Science: JIAS

Little Wall Lake, a shallow 104 ha glacial lake in Hamilton County, Iowa, has been manipulated for about 50 years by fishery managers in an attempt to provide a stable sport fishery. Managers have used dredging, water level manipulation, aquatic vegetation control, mechanical fish removal and fish eradication with toxicants, sport fish stocking, introduction of piscivorous fish, artificial habitat structures, and winter aeration. Attempts to stabilize the fishery have been unsuccessful, and because of overpopulation and stunting of panfishes, total fish eradications were conducted in 1977 and 1989. We review the history of management efforts on the lake, and suggest …

Three Botanists: Bessey, Pammel, And Hayden, Duane Isely, Lois Tiffany Jan 1992

Three Botanists: Bessey, Pammel, And Hayden, Duane Isely, Lois Tiffany

Journal of the Iowa Academy of Science: JIAS

Bessey was a multidirectioned innovator and evangelist of botanical education, conservation, and scientific agriculture. For example, he initiated the first undergraduate laboratory using microscopes for botany instruciton and he had no peer as a botany teacher in the latter part of the 19th century. His enthusiasm about the natural history of Iowa and surrounding states broadened the horizons of innumerable students and he was one of the founders of the Iowa Academy of Science. An organization man, Bessey quickly became president of any group with which he became affiliated, and eventually was both nationally and internationally known through his text …


Mass Dependent Loss Of Resolution In Radially Inhomogeneous Exb Ion Traps, Mark A. Capron, Susan S. Haskin, Curtiss D. Hanson Jan 1992

Mass Dependent Loss Of Resolution In Radially Inhomogeneous Exb Ion Traps, Mark A. Capron, Susan S. Haskin, Curtiss D. Hanson

Journal of the Iowa Academy of Science: JIAS

ExB ion traps, such as Fourier transform Ion Cyclotron Resonance mass spectrometers (FY:ICR), mass analyze sample ions based on differences in their cyclotron frequencies in a homogeneous magnetic field. The high resolution mass measurements of FT-ICR are based on the relationship between the frequency of the cyclotron orbit and the mass-to-charge (m/q) ratio of an ion. Both the orbit and the frequency/mass relationship result from the radial forces on the ion. Ions trapped by inhomogeneous electric fields experience different magnitudes of the radial electric fields at different positions resulting in a positionally dependent frequency. Such differences in orbital frequencies for …


Parasitology As An Interpretive Tool In Archaeology, Karl J. Reinhard Jan 1992

Parasitology As An Interpretive Tool In Archaeology, Karl J. Reinhard

Karl Reinhard Publications

Parasitological studies of archaeological sites can be used to interpret past behavior and living conditions. During the 1980s problem-oriented research into prehistoric- and historical-period parasitism developed and resulted in thefield of archaeoparasitology. Archaeoparasitology attempts to integrate parasite data into archaeological theory and interpretation. Within the last decade, four major archaeoparasitological laboratories emerged. They developed interpretive frameworks that apply parasitological data to a remarkable variety of prehistoric behaviors. Parasite remains can be used to reconstruct aspects of diet, health, and other behaviors such as transhumance and trade. Finally. analysis of the distribution of parasite remains can be used to interpret aspects …


Trypanosome Infection Rates In Tsetse Flies (Diptera: Glossinidae) And Cattle During Tsetse Control Operations In The Kagera River Region Of Rwanda, Steve Mihok, Leonard H. Otieno, Christopher S. Tarimo Jan 1992

Trypanosome Infection Rates In Tsetse Flies (Diptera: Glossinidae) And Cattle During Tsetse Control Operations In The Kagera River Region Of Rwanda, Steve Mihok, Leonard H. Otieno, Christopher S. Tarimo

All Peer-Reviewed Publications

Trypanosome infections were monitored in three species of tsetse fly (Glossina pallidipes Austen, G. morsitans centralis Machado, and G. brevipalpis News-tead) at four locations in the Kagera River region of Rwanda from May 1989 to September 1990. Two of the four areas (Mpanga Ranch and Bukora Ranch) were subjected to tsetse fly suppression operations with odour-baited traps. Proboscis infections of the Trypanosoma congolense and T. vivax types accounted for roughly equal numbers of the 207 mature infections detected (3.8%). Variation in infection rates was area-specific rather than tsetse species-specific. Order of magnitude differences in tsetse fly densities among areas were …


Oviposition, Larval Arrest And Establishment Of Chilo Partellus (Lepidoptera: Pyralidae) On Maize Genotypes During Anthesis, Harish Kumar Jan 1992

Oviposition, Larval Arrest And Establishment Of Chilo Partellus (Lepidoptera: Pyralidae) On Maize Genotypes During Anthesis, Harish Kumar

All Peer-Reviewed Publications

The oviposition, larval arrest and establishment by the stem borer Chilo partellus (Swinhoe) were measured on different maize genotypes during anthesis. The maize genotypes tested were: Inbred A (Susceptible), Mp 704, MBR-8637, MBR-8650, MBR-8668, Poza Rica 7832, ER-29 SVR, Katumani Composite B, MMV 400, Bulk CG 4141, and ICZ2-CM. The moths oviposited on the middle leaves of the plant and the neonate larvae moved to leaf sheaths and ear husks to feed (arrest). As they grew older, the larvae invaded the stem, ear shanks and tassel to complete feeding (establishment) and to pupate. The response of the stem borer differed …

Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Baughn M. Bryant Jr Jan 1992

Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Baughn M. Bryant Jr

Karl Reinhard Publications

The most remarkable dietary remains recoverable from archaeological contexts are coprolites. Coprolites are desiccated or mineralized feces that are preserved in sheltered and open sites in arid regions, primarily in the New World. These dietary remains are remarkable from several perspectives. They typically contain a variety of macroscopic and microscopic remains that form interrelated data sets for the reconstruction of diets. Because contexts containing coprolites are typified by excellent preservation, the remains coprolites contain tend to be in better states of preservation than dietary remains recovered from nonfecal deposits. Coprolites also contain the well-preserved remains of intestinal parasites and pathogens …


Vertebral Pathology In Prehistoric And Historic Skeletons From Northeastern Nebraska, Karin L. Sandness, Karl J. Reinhard Jan 1992

Vertebral Pathology In Prehistoric And Historic Skeletons From Northeastern Nebraska, Karin L. Sandness, Karl J. Reinhard

Karl Reinhard Publications

Vertebral pathology has long been a useful criterion for anthropologists in the assessment of activity patterns, stress, and general health of extinct peoples. This method of analysis, however, has never been applied to the peoples of the Nebraska Great Plains. This study is the first to concentrate on the indigenous Native Americans of this region, examining the spinal pathology present in the prehistoric and historic skeletal remains. Pathology present in the form of spondylolysis, Schmorl's nodes, osteophytosis (degenerative disc disease), and osteoarthritis (degenerative joint disease), provides evidence to suggest differing activity patterns and levels of stress in Plains groups before …


Dan Canyon Burial: A Piii Burial In Glen Canyon National Recreation Area, Steve Dominguez, Karl Reinhard, Kari L. Sandness, Cherie A. Edwards, Dennis Danielson, F. A. Calabrese, Chris Kincaid Jan 1992

Dan Canyon Burial: A Piii Burial In Glen Canyon National Recreation Area, Steve Dominguez, Karl Reinhard, Kari L. Sandness, Cherie A. Edwards, Dennis Danielson, F. A. Calabrese, Chris Kincaid

Karl Reinhard Publications

The Dan Canyon burial was discovered at a time when the philosophy, ethics, and legislation concerning the study of human remains are in a state of flux. A number of important sensitive issues germane to managers, archeologists, and American Indians are discussed in the introduction. The subsequent analysis provides a detailed scientific account of these remains and a glimpse of a segment of a people's past lifeway while remaining sensitive to the wishes of the American Indians.

The burial and associated grave goods of site 42SA21339 were exposed by wave action in a location frequented by boaters at the Glen …


Disruption Of Glossina Morsitans Morsitans (Diptera: Glossinidae) Eclosion Behaviour: A Novel Method For Evaluating The Action Of Neurotoxic Agents, J. Ždárek, D. L. Denlinger Jan 1992

Disruption Of Glossina Morsitans Morsitans (Diptera: Glossinidae) Eclosion Behaviour: A Novel Method For Evaluating The Action Of Neurotoxic Agents, J. Ždárek, D. L. Denlinger

All Peer-Reviewed Publications

As the tsetse fly, Glossina morsitans morsitans Westwood extricates itself from the puparium and moves upward through the soil the ptilinum expands and contracts rhythmically and thus generates a stereotypic behavioural pattern that persists for up to 10 h if the tsetse fly remains confined. The response, which is easily recorded tensometrically from the movements of the ptilinum, can be exploited as a tool for evaluating the behavioral response of tsetse flies to various neurotoxic agents. The behavioural assay proves useful in providing precise information about the latency of the response and lethal time, and can suggest likely modes of …


Factors Affecting Seasonal Dispersal Of The Tsetse Flies Glossina Pallidipes And G. Longipennis (Diptera: Glossinidae) At Nguruman, South-West Kenya, R. Brightwell, R. D. Dransfield, B. G. Williams Jan 1992

Factors Affecting Seasonal Dispersal Of The Tsetse Flies Glossina Pallidipes And G. Longipennis (Diptera: Glossinidae) At Nguruman, South-West Kenya, R. Brightwell, R. D. Dransfield, B. G. Williams

All Peer-Reviewed Publications

Seasonal changes in the distribution of the tsetse flies, Glossina pallidipes Austen and G. longipennis Corti, along a transect from riverine thickets out into open plains were monitored along with tsetse density, climatic factors, vegetation and host abundance. Dispersal of tsetse into open country was quantified using the mean spread. During and after the rains both species extended their distribution out into open country up to at least 3.5 km from riverine thicket areas. The mean spread of G. longipennis was greater than that of G. pallidipes. The spread of males and females was very similar, as was the spread …


History Of Mammal Study In Iowa, John B. Bowles Jan 1992

History Of Mammal Study In Iowa, John B. Bowles

Journal of the Iowa Academy of Science: JIAS

The first records of mammals in Iowa were from explorers, survey parties heading westward and early seeders. Generation of checklists of state mammals began in 1840 and culminated with the annotated list by Scott (1937) and biogeographic analysis by Bowles (1975). Recent focus has been on rare species status and mammalian ecology, e.g., Loess Hills, riparian habitat, agricultural practices, and reestablished grasslands.
