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

Journal of the Iowa Academy of Science: JIAS
Harold W. Beams, long time Professor of Biology at the University of Iowa, died at his home in Iowa City on January 26, 1992 after an illness of several months. Professor Bearns was born in Belle Plaine, Kansas on August 3, 1903. He received the B.A. Degree in 1925 from Wichita State University, the M.A. Degree in Zoology in 1926 from Northwestern University, and the Ph. D.

Fifty Years Of Fisheries Management M An Obstinate Prairie Lake, Dennis L. Scarnecchia, James R. Wahl
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 …
Diatoms Of Northeastern Iowa Fens, Stephen P. Main, David E. Busch
Diatoms Of Northeastern Iowa Fens, Stephen P. Main, David E. Busch
Journal of the Iowa Academy of Science: JIAS
Analysis of water samples from 10 fens in NE Iowa, collected 13-14 November 1987, revealed a gradient from acid, low conductivity water conditions (pH 5.6, alkalinity 30 mg/I HCO, conductivity 65 μmho, total hardness 30 mg/I Ca) to circumneutral, moderately conductive conditions (pH 7 .2, alkalinity 390 mg/I, conductivity 705 μmho, total hardness 380 mg/I Ca). Three sites along this gradient were sampled 15 May 1988 and 3 September 1988 to evaluate seasonal variation in water conditions. Examination of composite diatom samples collected concurrently with the water samples yielded 150 taxa, of which 14 are new Iowa distributional records and …
Book Review: Landforms Of Iowa, Michael L. Thompson
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 …

Three Botanists: Bessey, Pammel, And Hayden, Duane Isely, Lois Tiffany
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 …
Annual Report Of The Iowa Academy Of Science, 1991-92, Paul E. Rider
Annual Report Of The Iowa Academy Of Science, 1991-92, 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, 1991 to June 30, 1992. 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.

Floristic Composition And Conservation Status Of Fens In Iowa, John A. Pearson, Mark J. Leoschke
Floristic Composition And Conservation Status Of Fens In Iowa, John A. Pearson, Mark J. Leoschke
Journal of the Iowa Academy of Science: JIAS
Over 200 extant fens of varying condition were documented during an extensive inventory conducted in Iowa between 1986 and 1991. Approximately half of the extant fens support endangered, threatened, special concern, or other rare plant species. Approximately 25 fens are outstanding conservation prospects with intact vegetation, high species richness, and rare species. Nearly 40% of all potential fen sites have been destroyed by cultivation or damage; another 30% remain unknown due to lack of a field visit, but most appear on aerial photographs to be very small, disturbed fragments. In addition to their traditionally recognized range in northwest Iowa, fens …

Charles Rueben Keyes And The History Of Iowa Archaeology, William Green
Charles Rueben Keyes And The History Of Iowa Archaeology, William Green
Journal of the Iowa Academy of Science: JIAS
Charles Reuben Keyes (1871-1951) achieved recognition during his lifetime as the "founding father" of Iowa archaeology, and later assessments confirmed and reemphasized Keyes' stature as Iowa's pioneer archaeologist. The collections and documents Keyes compiled, his interpretive publications, and the records of field work he coordinated have proven more valuable to Midwest and Plains archaeology every year. This article emphasizes Keyes' involvement in the development of professionalism in American archaeology and Iowa’s position in the growth of the discipline from 1920 to 1950. Keyes' contacts with the principal archaeologists of his era ensured Iowa’s involvement in the development of survey methods …
