Hormonal Regulation Of Gene Expression M The Aleurone Layers Of Cereal Grains, Tuan-Hua David Ho

Journal of the Iowa Academy of Science: JIAS

The aleurone layers of cereal grains offer a convenient system for studies of the molecular action of two plant hormones, gibberellins (GA) and abscisic acid (ABA). Gibberellins induce the synthesis of ix-amylase and several other hydrolytice enzymes. The action of GA is essentially at the transcriptional level, it enhances the level of steady-state levels of ix-amylase mRNAs, the rate of transcription of ᴕ-amylase genes and the activity of a trans-acting factor which interacts with specific regions of ix-amylase genes. Abscisic acid antagonizes the effect of GA by inhibiting the induction of hydrolytic enzymes, yet the effect of ABA itself is …

Relative Abundance Of Eastern Screech-Owls In A South-Central Iowa Township, David E. Geus, John B. Bowles

Journal of the Iowa Academy of Science: JIAS

Roadside playback surveys of Eastern Screech-Owls were conducted each spring and fall from September 1984 through April 1986 in Summit Township, Marion County, Iowa. An average of 18 screech-owls were located during each survey, often near riparian woodland. Screech-owl population densities (0.1-0.2 owls/km²) were comparable to those in other regions.

Genetic Variation Among And Within S1 Progenies Of Maize, R. J. Getschman, A. R. Hallauer

Journal of the Iowa Academy of Science: JIAS

Inbred line development consumes a great portion of the breeder's time and resources in maize (Zea mays L.) breeding programs. Source populations for line development often are developed by selfing F2 populations developed from elite line crosses. Visual selection is practiced among and within selfed progenies during the selection process for one or two generations before evaluated in testcrosses for combining ability. Effective discrimination among and within inbred and testcross progenies depends on the amount of genetic variation present. The objective of this study was to determine the effectiveness of selection among and within S₁ progenies developed from crosses …

Area-Dependent Changes In Bird Densities In Iowa Marshes, Mike Brown, James J. Dinsmore

Journal of the Iowa Academy of Science: JIAS

Species richness and density of Iowa marsh birds were positively correlated with marsh area, but area accounted for 69% of the variation in species richness and only 19% of the variation in density. Although densities of five of nine species examined correlated with marsh area, total density was not significantly correlated with area when the effects of species richness were eliminated. Area was the most frequent significant variable in regression equations for species richness, total density, and the densities of nine individual species on six variables. Unlike species-area relationships, density-area relationships are relatively weak, and knowledge of other ecological factors …

Food Habits Of The Northern Saw-Whet Owl In Central Iowa: Effects Of Roost Location, Stephen J. Dinsmore, William R. Clark

Journal of the Iowa Academy of Science: JIAS

During the period 1979-89, 900 northern saw-whet owl (Aegolius acadicus) pellets with identifable remains of prey were collected at 18 central Iowa locations. Peromyscus were the most frequent prey consumed, comprising 81.2% of all prey items. Other prey species were voles (Microtus), western harvest mice (Reithrodontomys megalotis), shrews (Blarina brevicauda, Sorex cinereus, and Cryptotis parva), and a single unidentified bird. Peromyscus comprised the largest proportion of pellets from different successional stages. There were significant differences for four prey groups (Peromyscus, Microtus, Reithrodontomys, and shrews) among years. Peromyscus and R. megalotis showed significant differences among locations. Microtus and shrews were variable …

Regulation Of Phytochrome Gene Expression, J. T. Colbert, S. A. Costigan, P. Avissar, Z. Zhao

Journal of the Iowa Academy of Science: JIAS

In etiolated oat seedlings exposure to red light results in a decrease in the transcription of the phytochrome genes, the abundance of phytochrome mRNA, and the level of phytochrome protein. Phytochrome itself serves as the photoreceptor for the response of decreased mRNA and transcription levels. The decrease in phytochrome mRNA is sensitive to low levels of Pfr. Even green "safelight" is capable of inducing a decrease in phytochrome mRNA abundance. Barley phytochrome mRNA abundance is also dramatically down-regulated in response to red light but other plant species vary in their ability to decrease phytochrome mRNA abundance after red light treatment. …

Change and continuity in German relations with the East from the original German colonization of Eastern Europe during the Middle Ages until the present will be examined. Special attention will be paid to the historical, geographical, and economic factors that have influenced German behavior. The paper will attempt to show that the East has always held an attraction and fascination for the Germans, an attraction that has often led to German efforts to dominate …

Handwriting: Past To Present, Carol Collins

Graduate Research Papers

Is handwriting becoming a lost art? In this technological society where forms must be printed or typed clearly are we losing our ability to write our language? When the typewriter came into popular use, it was claimed handwriting would no longer be a needed skill. This has not been proven true. Templin (1960) concluded that while the typewriter gradually supplanted handwriting for making permanent records, "there ls strong evidence to support the belief that all children now in school will need handwriting in their business and social lives for many years to come" (p. 164).

Russian Nationalism And Pamiat, Brian Granger

Presidential Scholars Theses (1990 – 2006)

More than seventy years after the October Revolution a crisis in the Soviet Union has caused its citizens to suffer a loss of faith. This disillusionment seemingly stems from the lack of success in economic reform and the chaos of the democratization policy implemented since the rise to power of M.S. Gorbachev in March 1985. The following reaction has not merely condemned Horbachev's "experimentation" with the Pandora's box of perestroika and glasnost'; the first years of the 1990s have also seen the increasing tendency to blacken the whole of Soviet History, to trace the root of all the ills of …

Educating Educators In The Selection, Design, And Utilization Of Educational Media, Sara B. Baumhover

Graduate Research Papers

Today, as in the past, there are various factors affecting education and calling for changes. Firstly, there is a constant influx of technology and materials into educational and training systems. Secondly, the characteristics and needs of learners are changing. Finally, the problems affecting both learners and educators are increasing. Rather than passively accepting change, Ways (1964) has suggested that humans become active participants. For educators, this means altering instructional strategies to incorporate new mediums (Romizowsky, 1988). Educators need to have a voice and exercise control over the way in which messages are presented. In order to do so, educators need …

Literature-Based Reading As A Curricular Option For The Gifted Reader, Sally Simdorn

Graduate Research Papers

In 1984 Mangieri and Madigan initiated a survey that was sent to 150 schools across the United States. Its purpose was to find out what type of reading curriculum was being implemented for their gifted readers. They found that the same basal series which was used for regular readers also was being used for gifted readers. Some of the schools did accelerate students through the basal and/or use enrichment activities, but there was a wide variance.
