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 …

The Status Of Three Uncommon Salamanders (Amphibia: Caudata) In Iowa, Jeffery D. Camper

Journal of the Iowa Academy of Science: JIAS

The smallmouth salamander [Ambystoma texanum (Matthes)], blue-spotted salamander (Ambystoma laterale Hallowell), and central newt [Notophthalmus viridescens louisianensis (Wolterstorff)] were studied in Iowa from fall 1982 through summer 1984. All three species have declined in abundance in Iowa. A. texanum is more abundant and widespread than was previously suspected, but is declining due to habitat destruction. Apparently, only two populations of A. laterale remain in Iowa. N. v. louisianensis has also declined due to habitat destruction, with only three populations known. All three species require ponds in or adjacent to forest. A. ta was found primarily in riparian …

Science Learning Matters: Iowa Within The Context Of The Naep Assessments, Jack A. Gerlovich

Iowa Science Teachers Journal

The National Assessment of Educational Progress (NAEP) report (Mullis and Jenkins, 1988) states that "science exerts a pervasive influence on the quality of the lives of all citizens, and that it is essential that all productive citizens be able to understand and resolve the increasing number of societal problems related to science and technology." Our national position as a world leader is dependent upon such knowledge and skills. In Iowa, a state striving to improve its national and world economic status, these NAEP analyses are critical.

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 …

Economic Changes From The Use Of Biotechnology In Production Agriculture, Loren W. Tauer

Journal of the Iowa Academy of Science: JIAS

The potential economic impact of biotechnology in production agriculture is discussed. There are challenges and difficulties in completing economic research when little production information is available on biotechnologies. I argue that little impact differences exist between cost-reducing versus output-increasing technological change. Rapid technological change results in low average returns in agriculture but continuous early innovators earn higher returns. Various plant and animal technologies are presented and discussed.

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 …

The Development Of Student Leadership Through Student Government And Student Organizations, Oren R. Griffin

Graduate Research Papers

According to Wilton Pruitt (1965), Dean of Student Personnel Services at Trenton State College, "leadership is a functional complex of attitudes, sensitivity, and skill, rather than a special ability held by an elect few" (p. 35). Too often, people are elected to an office and are quickly, without question, identified as leaders. Whether it is on a college campus or in city government, winning an election does not qualify one as a leader. A leader is one with the ability to function effectively in groups and to motivate others. More specifically, leadership is, as defined by Mabey (1985), "... being …

Mathematics And The Young Child, Colleen Christiansen

Graduate Research Papers

Educators are continuously searching for better techniques for working with young children and establishing developmentally appropriate curricula. We have witnessed a great surge of interest in the work of Piaget, and its many implications for educating young children. His investigation into development of a number of logical, physical, and mathematical notions contains several ideas which, if suitably explored and developed, could prove valuable to educators and instructional planners (Ginsburg and Opper, p. 218). There are indications from Piagetian research, relevant to both affective and cognitive development of children, that a mathematics program for young children should be one of exploration …
