Accepting The Challenges: The Emerging Role Of Grand Rapids Community College In Preparation Of New Teachers, J. Hesse
Journal of Mathematics and Science: Collaborative Explorations
In 1992, Grand Rapids Community College (GRCC) was one of six community colleges invited to participate in a NSF initiative to improve science and mathematics teaching within the state of Michigan. This initiative included all public teacher preparation institutions in the state. GRCC has responded to this challenge by: (1) designing a new course in Physical Science for future teachers; (2) creating the GRCC Teacher Education Pathway and the GRCC Teacher Education Center; (3) forming a local alliance with Grand Rapids Public Schools and Grand Valley State University for the purpose of recruiting and supporting minorities in mathematics and science …
Pre-Education Programs: A Comprehensive Project At Henry Ford Community College, D. Zopf, L. Smyrski
Pre-Education Programs: A Comprehensive Project At Henry Ford Community College, D. Zopf, L. Smyrski
Journal of Mathematics and Science: Collaborative Explorations
Henry Ford Community College (HFCC) in Dearbom, Michigan is a two-year institution of higher education serving a diverse student population of approximately 13,000 students. In addition to providing a broad array of technical and vocational programs, the College provides the first two years of a baccalaureate program. However, the transferability of these programs is not assured. In the absence of a mandated state-wide curriculum, two- and four-year colleges and universities in Michigan develop courses and programs independently, and the transfer of courses between institutions is determined independently by the respective departments. The end result is often loss of credit when …

Iowa's Changing Forest Resources, Steven E. Jungst, Donald R. Farrar, Michael Brandrup
Iowa's Changing Forest Resources, Steven E. Jungst, Donald R. Farrar, Michael Brandrup
Journal of the Iowa Academy of Science: JIAS
After a period of decline in area extending from the 1850s to 1974, Iowa's forest area increased between 1974 and 1990. Although the area increase is encouraging, it may be fleeting. In addition, changes in forest stand structure and forest ownership patterns along with other pressures may make it difficult to maintain healthy forest ecosystems in the future. Notes from the original land survey in Iowa coupled with information from U.S. Forest Service forest inventories make it possible to look at changes in forest area and forest tree types. Unfortunately, similar long-term data do not exist to make possible a …
Leafy Spurge (Euphorbia Esula L.) Spread In Iowa, S. C. Huerd, S. E. Taylor
Leafy Spurge (Euphorbia Esula L.) Spread In Iowa, S. C. Huerd, S. E. Taylor
Journal of the Iowa Academy of Science: JIAS
Leafy spurge (Euphorbia esula L.), a noxious perennial weed spreading south from the northern Great Plains into Iowa, is considered a threat to Iowa's Prairie preserves because it is an aggressive non-native plant that dominates the landscape through rapid sexual and asexual reproduction. Methods to control leafy spurge include cultural and chemical controls, and biological controls are currently being developed. In 1992 and 1993 we surveyed the extent of leafy spurge spread in Iowa and found 26 of 99 Iowa counties with leafy spurge populations. Iowa's leafy spurge populations are rapidly expanding on untilled lands such as roadsides, especially in …
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 …
Status Of Aquatic Vascular Plants 1n Iowa's Natural Lakes, G. S. Phillips
Status Of Aquatic Vascular Plants 1n Iowa's Natural Lakes, G. S. Phillips
Journal of the Iowa Academy of Science: JIAS
Conversion of wetlands to agricultural land during the settlement of Iowa has resulted in a significant decline in the total area of lake habitat in the state. This reduction in area, combined with the degradation of remaining sites, resulted in dramatic reductions in aquatic vascular plant populations associated with Iowa's natural lakes. While declines in plant species inhabiting fen, bog, seepage, prairie pothole, and marsh type wetlands have been extensively documented, few quantitative data exist for lake type wetlands. During the summer of 1996, a total of 86 natural lakes in Iowa were surveyed for aquatic vascular plants. Many of …
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 …
Distribution And Ecology Of The Morels And False Morels Of Iowa, L. H. Tiffany, G. Knaphus, D. M. Huffman
Distribution And Ecology Of The Morels And False Morels Of Iowa, L. H. Tiffany, G. Knaphus, D. M. Huffman
Journal of the Iowa Academy of Science: JIAS
The distribution, time of fruiting and habitats of morels and false morels in Iowa were documented during a 10 year survey (1984-1993). Distribution maps for each species also include information from published reports and from herbarium records. The true morel genus, Morchella, is represented in Iowa by five species. Three of these species, M. deliciosa, M. esculenta and M. crassipes, are sometimes interpreted as segments of one large, extremely variable species. M. semilibera and M. angusticeps also occur. M. angusticeps, a black morel, has not been previously reported from Iowa. Four false morels, two species in each of two genera, …

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 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 …

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.

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 …
