An Industry Perspective On The Benefits Of And Regulation Of Genetically Engineered Plants, Nicholas M. Frey

Journal of the Iowa Academy of Science: JIAS

The seed industry has routinely incorporated new technology into its research and development programs. Plant generic engineering is the most recent technology to be utilized for seed product development efforts. New sources of herbicide, insect, and disease resistance are being incorporated into crop plants using cellular and molecular biology techniques.

New regulatory guidelines have been developed which require regulatory approval before genetically engineered plants can be reseed in the field and ultimately marketed. The impact of these regulations on product development is unclear. Hopefully a dialogue will develop among industry, government agencies, and the public such that reasonable and appropriate …

Agronomic Performance Of Sorghum Hybrids Produced By Using Different Male-Sterility-Inducing Cytoplasms, A. J. Maves, R. E. Atkins

Journal of the Iowa Academy of Science: JIAS

Experiments were conducted in three environments in Iowa to obtain information on the effects of different cytoplasms on agronomic characters in grain sorghum (Sorghum bicolor L. Moench) hybrids. Compared with A1 cytoplasm, A2 and A3 cytoplasms delayed flowering; reduced the percentage of fertile pollen, the number of seeds per panicle, and grain yield; and increased 100-seed weight of the hybrids. Hybrids with A2 or A3 cytoplasm did not differ (p ≥0.05) from those in the A1 cytoplasm for plant height, panicles per plant, or for length, width, and area of the third and fourth leaves from the top of …

A Vascular Flora Of The Swaledale Railroad Prairie In North Central Iowa, Thomas L. Eddy

Journal of the Iowa Academy of Science: JIAS

"Railroad prairies" are remnant native grasslands that grow along railroad right-of-ways. The Swaledale railroad prairie, which is in north central Iowa, occurs along the Chicago and Northwestern Railroad Company right-of-way in Cerro Gordo County.

The railroad right-of-way and an abandoned sand pit, which lies adjacent to the railroad embankment, harbor a collection of tallgrass prairie remnants. The sand pit supplied earthen fill which was used to elevate the original railroad embankment, circa 1887. It is noteworthy that the method of excavation for fill material helped to preserve earthen knolls that are covered with original tallgrass prairie.

Plant collections were acquired …

A Charisma Model Of Telepathic Communication, James M. Donovan

Law Faculty Scholarly Articles

This paper opened by making some general criticisms of the state of parapsychological research: that it suffered from a lack of external validity and from uncritical acceptance of a flawed paradigm. The charisma model was offered as an attempt to rectify these problems. It allows for laboratory experiments to be designed which closely approximate genuine human interactions by shifting the paradigm for telepathy from that of energy transfers to one of communication events.

On The Nature And Antiquity Of The Manix Lake Industry, Douglas Bamforth, Ronald Dorn

Department of Anthropology: Faculty Publications

The antiquity of human occupation in the New World undoubtedly is one of the major unresolved culture-historical problems in North American prehistory. On the one hand, a dominant position with a long history in American archaeology (cf. Wilmsen 1965) holds that human beings arrived in the New World at the close of the Pleistocene, no longer than 12,000 years ago, and that Clovis sites represent the oldest occupation in the Americas (Haynes 1970; Martin 1973; Waters 1985). On the other hand, a less widely accepted school of thought sees a variety of evidence for human occupation in the Americas well …

The Allocation Of Parental Care Among The Ye'kwana, Raymond B. Hames

Department of Anthropology: Faculty Publications

It is well known that human children require more care or parental investment than any other primate species (Lancaster and Lancaster 1983). While this dimension of human behavior is well documented in the psychological literature for Euroamerican populations (Babchuck et al. 1985), it has received scant, quantitative attention by anthropologists working among tribal populations (for exceptions see Whiting and Whiting 1975, Katz and Konner 1981, Hurtado et al. 1985, Hewlett, this volume (Chapter 16), Turke, this volume (Chapter 10)). The role of alloparental care (care of non-offspring children) has received even less quantitative attention by social scientists (for a review …

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.

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 …

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 …

Evaluation Of Fish Eradication And Game-Fish Restocking In A Central Iowa Pond, Dennis L. Scarnecchia

Journal of the Iowa Academy of Science: JIAS

Changes in fish community and population structure associated with fish eradication and subsequent restocking were investigated in a small (0. 25 ha) impoundment in Boone County, Iowa. In September 1985, when fish were eradicated with rotenone, the fish community consisted of eight species. Large numbers of small bluegills (Lepomis macrochirus), green sunfish (Lepomis ryanellus), and stunted crappies (Pomoxis spp.) dominated the pond numerically, but seven large carp (Cyprinus carpio) and 18 large bigmouth buffalo (lctiobus ryprinellus) constituted 80% of the total biomass. The only quality angling (popular species of desirable size) was for a few largemouth bass (Micropterus salmoides) and …

Solvent Effects In Room Temperature Phosphorescence, Shane J. Helsenbeck, Catherine Haustein

Journal of the Iowa Academy of Science: JIAS

Room temperature phosphorescence (R TP) analysis is a technique in which solutions containing organic phosphors are applied to filter paper and dried in the absence of oxygen. Adsorption to the paper inhibits molecular vibrations and promotes phosphorescence. Although the solvent must be removed by volatilization before phosphorescence can occur, it appears that the nature of the solvent affects the intensity of the resulting phosphorescence. We examined the room temperature phosphorescence of p-aminobenzoic acid which had been dissolved in water, organic solvents, or mixtures of water and organic solvents. It was found that solvent volatility had little correlation with RTP intensity …

Using Life History And Ecology As Tools To Manage A Threatened Salamander Species, Scott R. Mcwilliams, Marilyn D. Bachmann

Journal of the Iowa Academy of Science: JIAS

Selected aspects of the life history and ecology of the small-mouthed salamander (Ambystoma texanum Matthes) relevant to the management of this threatened species in Iowa are presented. The population studied utilizes flooded woodland habitat during courtship, breeding and egg laying, and during the entire larval period. Larval foraging strategies in this habitat included ontogenetic but no diel shifts in prey selection. Synchronous, nocturnal breeding migration allowed effective use of drift fences fur capture of adults used in captive breeding, courtship behavior studies, and the estimation of breeding population size. Large numbers of spennatophores, apparently indiscriminate mate choice, and the relatively …

Soil N Availability And Nitrogen Harvest Index Of Oats, N. Md. Kairudin, K. J. Frey

Journal of the Iowa Academy of Science: JIAS

A population of 480 random lines of oats (Avena sativa L.) was grown on soil that received no application of nitrogen (N) or 112 kg of N ha^-1 (defined as low- and high-N environments, respectively) to evaluate the effect of N availability in the soil on the plant's ability to partition N between vegetative tissue and the grain, a ratio defined as nitrogen harvest index. Also, comparisons were made between low and high-N environments for grain yield, straw yield, biological yield, groat protein yield, groat protein percentage, vegetative protein yield, straw protein percentage, total plant protein yield, and harvest …

Seasonal Composition Of Benthic Diatom Associations In The Cedar River Basin (Iowa), Stephen P. Main

Journal of the Iowa Academy of Science: JIAS

This is the first detailed report on the taxonomy and ecology of diatoms in the portion of the upper reaches of the Cedar River basin in Iowa. This paper describes the diatom taxa from shallow benthic substrata collected quarterly between 11 October 1975 and 19 February 1977 at 14 sampling stations. Just over 500 frustules were counted from each of the 216 samples obtained. Analysis of water samples collected at the same time as the diatoms indicates these screams have alkaline hard waters rich in nutrients with extreme turbidity level fluctuation at irregular intervals.

The 281 diatom taxa identified represented …
