The Habitat And Distribution Of The Stinkpot, Sternotherus Odoratus, In Iowa, Kristi K. Sutton, James L. Christiansen
The Habitat And Distribution Of The Stinkpot, Sternotherus Odoratus, In Iowa, Kristi K. Sutton, James L. Christiansen
Journal of the Iowa Academy of Science: JIAS
Twenty years of study have shown that the stinkpot, Sternotherus odoratus and the Illinois mud turtle (Kinosternon flavescens spooneri) occur in Iowa primarily in the Mississippi Alluvial Plain. Even though the turtles are found within a kilometer of each other, they are never sympatric. Illinois mud turtles are most often associated with ephemeral ponds and soils of nearly pure sand (Sparta sand and Chelsea loamy fine sand), whereas stinkpots inhabit permanent water, often fed by cold springs, and are limited to sandy, loamy soils (Aquolls and Perks sandy loam). Even though several new localities have been discovered for stinkpots, population …
Community Composition Of Dry Prairie In Iowa And Southeast Nebraska, Thomas R. Rosburg
Community Composition Of Dry Prairie In Iowa And Southeast Nebraska, Thomas R. Rosburg
Journal of the Iowa Academy of Science: JIAS
Results from quantitative research on the community composition of dry prairies across Iowa were consolidated from three different studies completed since 1983. Information is provided on the distribution and abundance of 204 dry prairie species. The most abundant species included little bluestem (Schizachyrium scoparium (Michx.) Nash), big bluestem (Andropogon gerardii Vitman), side-oats grama (Bouteloua curtipendula (Michx.) Torrey), prairie dropseed (Sporobolus heterolepis (Gray) Gray) and Kentucky bluegrass (Poa pratensis L.). Multivariate analyses were completed using two independent measures of species abundance-relative cover and community constancy. When relative cover was used to determine community composition, the abundance of graminoids (tallgrasses vs. mid-grasses) …
Osmia Spp. Reared In Artificial Nesting Sites In A Backyard Environment, R. L. Wilson, C. A. Abel, S. G. Mcclurg
Osmia Spp. Reared In Artificial Nesting Sites In A Backyard Environment, R. L. Wilson, C. A. Abel, S. G. Mcclurg
Journal of the Iowa Academy of Science: JIAS
Controlled pollination in field cages is used at the United States Department of Agriculture - Agricultural Research Service North Central Regional Plane Introduction Station (NCRPIS) for seed increase of several plane species. Honey bees, Apis mellifera L., have been used almost exclusively for several years. Recently we began investigating other pollinating insects for controlled pollination. 0smia cornifrons (Radoszkowski), a solitary bee imported from Japan, has been an excellent early-season pollinator. We placed domiciles of these bees in backyards of the NCRPIS staff to aid us in providing adequate numbers of bees for use in field cages the following growing season. …

Book Review: The Tallgrass Restoration Handbook: For Prairies, Savannas, And Woodlands, Stephen D. Hendrix
Journal of the Iowa Academy of Science: JIAS
The Tallgrass Restoration Handbook: For Prairies, Savannas, and Woodlands. Stephen Packard and Cornelia F. Mutel, eds. 1997. Society for Ecological Restoration. 463 pages. ISBN 1-55963-319-0 hdbd.
The publication of the Tallgrass Restoration Handbook is an enormous step in the right direction for people who have already learned to appreciate and admire the beauty and utility of prairies and who now want to roll up their sleeves and begin the restoration of their own bit of tallgrass prairie. All of this volume excluding the first two introductory chapters (Part I) is dedicated to the practical aspects of prairie restoration.
A Municipal Inventory And Evaluation Of Natural Areas: History And Methodology, William R. Norris, Donald R. Farrar
A Municipal Inventory And Evaluation Of Natural Areas: History And Methodology, William R. Norris, Donald R. Farrar
Journal of the Iowa Academy of Science: JIAS
An inventory of natural areas in the vicinity of Ames, Iowa was conducted (1990-1994) in response to conflicts arising when significant natural areas were encountered on lands approved for development by the City of Ames (Iowa) Planning Office. Methods for objective evaluation of woodland and prairie quality were developed for use during the inventory. The woodland method is based on four components: I) Diversity of expected species, H) Structure of canopy and understory layers, III) Fidelity of species to the habitat and IV) absence of Introduced Species. Rules are explicitly stated for the scoring of each component for both the …
Managing Seedling Emergence Of Cuphea In Iowa, W. W. Roath
Managing Seedling Emergence Of Cuphea In Iowa, W. W. Roath
Journal of the Iowa Academy of Science: JIAS
Cuphea, a western hemisphere genus of some 260 species, has been proposed as a domestic source of medium-chain fatty acids. These fatty acids are used primarily in soap and detergent manufacture and are presently extracted from imported tropical oils or from petroleum. Considerable difficulty in obtaining consistent plant stands with direct seeding has been experienced at two Iowa locations. Trials were initiated in 1987 and continued through 1994 to test various treatments upon seedling emergence of C. laminuligera Koehne, C lanceolata Ait., and hybrid C. viscosissima Jacq. X C. lanceolata. These treatments included planting depths from 1.3 to 6.4 cm, …
Introduction To The 1997 Symposium On Iowa's Declining Flora And Fauna, Cornelia F. Mutel
Introduction To The 1997 Symposium On Iowa's Declining Flora And Fauna, Cornelia F. Mutel
Journal of the Iowa Academy of Science: JIAS
In 1980, Iowa's biologists and ecologists gathered at the 92nd annual meeting of the Iowa Academy of Science to present a symposium on the state's declining flora and fauna. Papers were published a year later in a single issue of The Proceedings of The Iowa Academy of Science (Vol. 88, No. 1), which has since been widely cited and much used as a baseline for research efforts. The symposium was a noble undertaking, for although the highly altered composition of Iowa's presettlement ecology had been widely recognized throughout the previous century, no single publication or gathering to that date …
Iowa's Avifauna: Recent Changes And Prospects For The Future, James J. Dinsmore
Iowa's Avifauna: Recent Changes And Prospects For The Future, James J. Dinsmore
Journal of the Iowa Academy of Science: JIAS
Iowa's avifauna has changed dramatically since 1980. The state list now has 40 additional species and totals 398 species, the most of any vertebrate group. Four species that had not previously nested in Iowa (Ring-billed Gull, Great-tailed Grackle, House Finch, Eurasian Tree Sparrow) and four whose nesting populations had disappeared (Double-crested Cormorant, Sandhill Crane, Piping Plover, Least Tern) now breed regularly here. Little Blue Heron, Cattle Egret, White-faced Ibis, Mississippi Kite, Prairie Warbler, and Red Crossbill nested for the first time but do not have established nesting populations. Trumpeter Swan, Peregrine Falcon, Greater Prairie Chicken, and Sharp-tailed Grouse have been …
Iowa's Wetlands, Present And Future With A Focus On Prairie Potholes, R. A. Bishop, J. Joens, J. Zohrer
Iowa's Wetlands, Present And Future With A Focus On Prairie Potholes, R. A. Bishop, J. Joens, J. Zohrer
Journal of the Iowa Academy of Science: JIAS
The vast prairie marsh-pothole complex that historically covered approximately 7 .6 millions acres in Iowa was reduced to less than 30,000 acres by 1980 when it was estimated that only 5,000 acres of prairie marsh and pothole habitat remained in private ownership. A bleak outlook for the future of wetlands was presented by Bishop (1981)." This outlook changed with the development of the North American Waterfowl Management Plan and the passage of two important pieces of legislation: the North American Wetlands Conservation Act and the Food Security Act of 1985. Protection of existing wetlands was afforded through the Swampbuster provision …

Lithologic And Structural Interpretation Of Gravity Data, Northeastern Iowa, Curtiss J. Hella, Richard L. Kellogg
Lithologic And Structural Interpretation Of Gravity Data, Northeastern Iowa, Curtiss J. Hella, Richard L. Kellogg
Journal of the Iowa Academy of Science: JIAS
A gravity survey was conducted over approximately 4600 square km of northeast Iowa. It was undertaken to provide detailed gravity coverage at approximately 1.6 km intervals and to model the source of several significant gravity and magnetic anomalies. 1,460 gravity stations were occupied in the survey area. Bouguer gravity and residual gravity anomaly maps were prepared, the latter using band-pass filter and trend-surface analysis techniques. The residual maps reveal that the large oval Bouguer gravity anomaly centered beneath Decorah can be traced to the southern border of the survey. Profiles crossing this feature were prepared from the Bouguer map and …
Iowa's Odonata: Declining And/Or Changing?, Robert W. Cruden, O. J. Gode Jr.
Iowa's Odonata: Declining And/Or Changing?, Robert W. Cruden, O. J. Gode Jr.
Journal of the Iowa Academy of Science: JIAS
We undertook a comprehensive survey of the Order Odonata in Iowa. Because the credibility of our conclusions derives from our collecting strategy and effort, we discuss our strategy in depth. We collected throughout the state (more than 500 sites in 94 counties), throughout the flight season (late May-early October), and tried to visit several habitats in each county. Our 7900+ observations made between 1993 and 1996 include approximately 2300 county records, 93 of the 110 species reported for the state, and eight species previously unknown from the state. At least 30 species are secure and occur across the state. Other …

Book Review - Birds In Iowa, Peter Wickham
Book Review - Birds In Iowa, Peter Wickham
Journal of the Iowa Academy of Science: JIAS
Here is a book that those who are interested in birds and their distribution in Iowa will absolutely have to possess. This volume is the successor to the book Iowa Birds, which was written by the above authors together with three others and published in 1984. It brings our understanding to the number of species of birds and their relative abundance in Iowa up-to-date. Although only twelve years elapsed between the publication of the previous volume and this one, the activity of those interested in identifying birds increased enormously during those years. In addition, their ability to identify and find …
A Literature Review And Survey Of The Status Of Iowa's Terrestrial Flora, Deborah Q. Lewis
A Literature Review And Survey Of The Status Of Iowa's Terrestrial Flora, Deborah Q. Lewis
Journal of the Iowa Academy of Science: JIAS
A survey of Iowa's floristic literature and herbarium resources indicates that while there is not uniform coverage of plant groups and regions, a great deal is known about the Iowa flora. Taxonomic and floristic studies are ongoing, despite evidence of a decreased number of researchers with expertise and interest in Iowa's flora and changing emphases in academic research. Current knowledge is sufficient for the production of an Iowa Flora, and an Iowa Flora committee to initiate this project is proposed.
Iowa's Declining Flora And Fauna: A Review Of Changes Since 1980 And An Outlook For The Future, Neil P. Bernstein
Iowa's Declining Flora And Fauna: A Review Of Changes Since 1980 And An Outlook For The Future, Neil P. Bernstein
Journal of the Iowa Academy of Science: JIAS
The status of Iowa's biodiversity was first summarized at a 1980 Iowa Academy of Science (IAS) symposium that was published in The Proceedings of the Iowa Academy of Science (Vol. 88, No. 1) in 1981. The 1980 symposium was updated in a recent IAS symposium, and the proceedings from this symposium are published, for the most part, in volume 105 of this journal. Most of the authors noted some positive trends, but, overall, species declines and habitat destruction remained a concern.

Safety Issues And Iowa Science Teachers, Jack A. Gerlovich, Ed Wilson, Rahul Parsa
Safety Issues And Iowa Science Teachers, Jack A. Gerlovich, Ed Wilson, Rahul Parsa
Journal of the Iowa Academy of Science: JIAS
The National Science Education Standards are providing an excellent blue print for improving science teaching for all students. However, the Standards are placing serious demands on teachers attempts to make science activities inquiry-based, real-life, open-ended, and directly applicable to today's students. This situation is further aggravated when teachers do not know essential science safety information from both federal and state governing agencies, as well as professional organizations. With proper training and tools, however, this problem can be positively addressed.
