Impact Of Biotechnology On Agriculture Productivity, Roger A. Kleese

Journal of the Iowa Academy of Science: JIAS

Biotechnology is a diverse array of technologies which today are in various stages of evolution and development. To understand them and the potential application of these technologies to agriculture, it is helpful to consider them in a historical perspective. In addition, it is important to understand the interdependence of biotechnologies on traditional, well developed technologies. The commercial development of biotechnology is more difficult than imagined even as recently as five years ago. Also, the problems being addressed generally demand a much better understanding of the physiology and biochemistry of the plant and animal systems under study. Nonetheless, there is a …

Predation By Ermine And Long-Tailed Weasels On Duck Eggs, Joseph P. Fleskes

Journal of the Iowa Academy of Science: JIAS

Ermine (Mustela erminea) and long-tailed weasel (M. frenata) predation on duck eggs was studied at Union Slough National Wildlife Refuge, Kossuth County, Iowa, 1984-85. Captive individuals of both species ate 2-4 duck eggs at a rate of 0.5-2 eggs per trial day. All eggs were moved but some were not opened. One hole, ringed with small fragments and "bite-outs'', was made in all eggs opened by captive weasels. In the field, the appearance of opened eggs, the pattern of egg loss and the amount of nest bowl disturbance were used to determine the number of nests depreciated by weasels. Egg …

Biotechnology: A Dilemma For Land-Grant Institutions, A. David Kline

Journal of the Iowa Academy of Science: JIAS

There is at least a prima facie moral tension between universities asserting land-grant principles and simultaneously sponsoring biotechnology. The core of the problem is the likely deleterious economic effects of biotechnology on rural communities -- the very constituency whose welfare is supposedly promoted by land-grant institutions. Considered are a number of responses to this tension including efforts to show that the tension is only apparent or that it can be eliminated through various public policies. It is argued that these "solutions" fail.

The upshot is that if the land-grant label is to be taken seriously, those institutions should begin allocating …

Some Genetic Characteristics Of Three Walleye Stocks In Iowa And The Impact Of Fry Stockings In The Cedar River, Vaughn L. Paragamian

Journal of the Iowa Academy of Science: JIAS

Fry stockings of walleye Stizostedion v. vitreum into the Cedar River, Iowa began in the early 1950's, and two studies of the success of these plants gave conflicting results. The objectives of my study were to identify some genetic characteristics in three stocks of walleye and to utilize these characteristics to assess the genetic impact of fry stockings in the Cedar River. Electrophoretic analysis of malate dehydrogenase (MDH) and isocitrate dehydrogenase (IDH) was completed for walleye stocks from the Mississippi and Cedar Rivers, and Big Spirit Lake, Iowa. Phenotypic frequencies of Mdh - B² and Mdh - B^{3 …}

The Taxonomy And Biology Of Strauzia (Diptera: Tephritidae), W. Bryan Stoltzfus

Journal of the Iowa Academy of Science: JIAS

The North American genus Strauzia is revised. Five new species are included with keys to adults of the 12 known species. Host plant, important larval characteristics, and life cycle information are given for 11 of the species. The evolution of the genus is discussed and 14 host plants are reported. All species bore in the stems of Asteraceae, pupariate in the crown area or in the soil, and are univoltine.

Annual Report Of The Iowa Academy Of Science, 1987-88, James G. Macmillan

Journal of the Iowa Academy of Science: JIAS

Since 1975 when a history of the Iowa Academy of Science was written for the centennial of the founding of the Academy, an Annual Report has acted as a continuing record of the Academy’s activities.

This report encompasses the year beginning July I, 1987 to June 30, 1988 and is based on minutes of committee meetings, Board minutes and recollections of the author. Each part represents a major activity of the Academy.

Biotechnology: Impact On Iowa's Agricultural Economy, Dwight T. Thomas

Journal of the Iowa Academy of Science: JIAS

Agriculture has always been an important cornerstone of Iowa's economy. The highly publicized difficulties in the agricultural economy in Iowa have highlighted both the importance of agriculture and pitfalls when agriculture is hit by adverse conditions. Iowa's agriculture and agricultural infrastructure have a heritage characterized by the development of very efficient production technology and the early use of innovative ideas. The early adoption of hybrid corn is but one example of the acceptance new technology. Today more than ever before there is a need for improved profitability and for the possibility of diversification of agricultural products in Iowa.

The following …

Dr. James G. Macmillan, Executive Director, Iowa Academy Of Science, 1983-1988

Journal of the Iowa Academy of Science: JIAS

The officers and Board of Directors of the Iowa Academy of Science dedicate this issue of the Journal of the Iowa Academy of Science to Jim Macmillan in recognition of his five years of exemplary leadership. During this period, Jim's managerial expertise has served the Academy well and membership has grown significantly. Under Jim's guidance the Academy has improved its financial base through sound fiscal policies, and important steps have been taken in the area of computerized record keeping and data management.

Benthic Macroinvertebrate Habitat Associations Of The Channelized Middle Missouri River, James B. Barnum, Roger W. Bachmann

Journal of the Iowa Academy of Science: JIAS

Benthic macroinvertebrates associated with navigation structures (dikes, dike pools, revetted banks) and abandoned channels on the Missouri River at the Iowa-Nebraska border were sampled in June, August, and October 1983 to determine the invertebrate community structure of these habitats. Invertebrate densities were greatest in the abandoned channel habitat (to over 13,000/m²), while diversities were greatest in the dike and revetment habitats. Greater habitat diversity contributed to greater organism diversity in the dike and revetment habitats while sediment homogeneity and stability presumably contributed to greater organism densities in the abandoned channel habitat. Dike pools had turbulent eddy currents, which …

A New Name For A Continuing Publication, Marilyn D. Bachmann, Roger W. Bachmann

Journal of the Iowa Academy of Science: JIAS

With this issue, the former Proceedings of the Iowa Academy of Science becomes The Journal of the Iowa Academy of Science, a change which coincides with the l00th annual meeting of the Academy. This concludes a process started in 1971 when the Proceedings became a quarterly periodical which also included papers that had not been presented at the previous annual meeting.

An Interpretative History Of The Proceedings Of The Iowa Academy Of Science, Don C. Norton

Journal of the Iowa Academy of Science: JIAS

The Proceedings of the Iowa Academy of Science was first published in 1887 and has continued yearly except for 1905. Business reports and contributed papers constituted most of the volumes. Publication of symposia has become more popular in recent years. Financial and mechanical problems have caused strains at rimes, but these have largely been solved after publication became independent of the State Printer.
