Profitability Of Crop Rotations In Iowa In A Stress Environment, Derrick N. Exner, R. M. Cruse

Journal of the Iowa Academy of Science: JIAS

Small grains crops have traditionally been included in Midwestern cropping systems, but their use is restricted by uncertain yields, poor prices, and lack of on-farm uses in operations without livestock. We compared the corn (Zea mays L.)-soybean (Glycine max (L.) Merr.) crop rotation to actual or simulated three-yr rotations at two sites in Iowa between 1986 and 1989. Water was generally more limiting than was nitrogen, which produced minimal response in the corn to which it was applied. April-November precipitation at Nashua, Iowa ranged from 59 to 111 % of average, while at Des Moines, Iowa it was 77% of …

Toxicity Of Cedar River Water And Sediment To Larval Walleye, Todd A. Phillips, Robert C. Summerfelt

Journal of the Iowa Academy of Science: JIAS

Although all anthropogenic stressors affecting aquatic ecosystems have not been isolated, suspended solids, sediment, and pesticides are believed to be major factors in agroecosystems. In the spring of 1998 and 1999, static 48-h tests were conducted to determine the toxicity of water and sediment collected from the Cedar River to prolarval, postlarval I, and postlarval II walleye (Sttzostedzon vitreum). River water and sediment were not more toxic to any larval stage of walleye than reference water and sediment. Cedar River sediments, suspended solids, and water were examined for occurrence of the most common herbicides and insecticides in Iowa. No pesticides …

The Obispeno Chumash Indians: San Luis Obispo County's First Environmentalists, Sharon L. Marks

Theses Digitization Project

The primary focus of this project is with the interaction between nature and people. How did the Obispeno Chumash affect their surroundings and what was the outcome? Did changes occur in the environment when other people took over the care of the land? Over the last 250 years, the Obispeno Chumash land has evolved from an ecologically green dominion under their stewardship to the present day where the area is noted for its mission, recreational value, wealth of opportunity, and a nuclear power plant located between Morro Bay and Point Buchon along the ocean.

Unique Supported-Model Classes Of Logic Programs, Pascal Hitzler, Anthony K. Seda

Computer Science and Engineering Faculty Publications

We study classes of programs, herein called unique supported-model classes, with the property that each program in the class has a unique supported model. Elsewhere, the authors examined these classes from the point of view of operators defined relative to certain three-valued logics. In this paper, we complement our earlier results by considering how unique supported-model classes fit into the framework given by various classes of programs in several well-known approaches to semantics.

Introduction, Neil P. Bernstein

Journal of the Iowa Academy of Science: JIAS

In this issue, the Iowa Academy of Science honors three of our colleagues who passed away in 2000. Duane Isely, Larry Eilers, and George Knaphus shared many of the same interests. All three were botanists, although George's research on fungi and heterotrophic protistans relegated him to the botany departments only by default. However, more importantly, all three were teachers. I believe that one of the lessons that they would have taught was the need to carefully document present patterns if we are to understand the future. However, many biologists poorly support this concept today.

In Memoriam: Larry Eilers, Paul A. Christiansen

Journal of the Iowa Academy of Science: JIAS

Larry came to botany along an unusual route. His first college degree was in engineering. After a stint at secondary teaching Larry worked at Collins Radio in Cedar Rapids, then returned to UNI (SCI then) and took a master's degree in biology, He continued his study at the University of Iowa under Dr. Robert Thorne and took his Ph.D. in 1964. He did the flora of the Iowan Surface (the Iowan Drift in those days). He taught at Syracuse University and University of Indiana at Terra Haute before joining the faculty of the University of Northern Iowa.

Digital Library Of Thesis: Administration Side, Soo Noan Chew

Student Works (2000-2009)

Currently, the faculty promoted a plan to rethink the way graduate students present their theses. Traditionally, the theses were produced in paper fonn and storing in library. The access of student work through this method still facing a lot of problems including less timely public access to users, shelf space required for storage, no maintenance, resources are not fully used and cost of preparing theses are high. Thus, Digital Library of Theses is proposed to eliminate all the shortcomings mentioned above. Digital Library of Theses (administration side) is a web-based theses administration system for faculty that can cater about 3 …

Factors Associated With Occurrence And Density Of Wetland Birds In The Prairie Pothole Region Of Iowa, Steve E. Fairbairn, James J. Dinsmore

Journal of the Iowa Academy of Science: JIAS

Wetlands within wetland complexes in northwestern, north-central, and central Iowa were surveyed for bird use in 1997 and 1998. Species occurrence, species richness, and density of nesting species were related to wetland habitat variables. A habitat diversity index measuring the evenness of distribution of the different habitats within a wetland was the best predictor of species richness in both years. The habitat diversity index was also the best predictor of the occurrence of individual species in both 1997 and 1998. Eight of 11 species (7 3%) in 1997 and 13 of 18 species (72%) in 1998 had greater densities in …

Tests Of A Rotenone-Impregnated Bait For Controlling Common Carp, Joseph L. Bonneau, Dennis L. Scarnecchia

Journal of the Iowa Academy of Science: JIAS

An experimental rotenone-impregnated pelleted (approximately 10 mg/pellet) bait was tested in force-feeding and field-feeding experiments as a method of control for common carp (Cyprinus carpio). Mortality rates of force-fed fish ranged from less than 40% when fed one pellet to 100% when fed more than 10 pellets. Mortality occurred within 48 h. Mortality rates of control fish did not exceed 10%. In reservoir feeding trials in 1994 and 1995, carp were fed for 2-3 weeks on a non-toxic, vegetable-based bait dispensed by automatic feeders, followed by one feeding of the bait with rotenone added. Carp ceased feeding on the rotenone …

Recent Observations Of The Distribution And Status Of Bluntnose Darters And Crystal Darters In Iowa, Melvin C. Bowler

Journal of the Iowa Academy of Science: JIAS

The distribution and status of Iowa's fishes were last extensively described in Iowa Fish and Fishing (Harlan et al. 1987). Since then, numerous fish collections have been made in Iowa's interior and bordering rivers and streams. Excluding non-native species, there have been three documented accounts of new fish species distributional records in Iowa since 1987. In this paper, I describe new collections of crystal darter (Crystallaria asprella) and bluntnose darter (Etheostoma chlorosomum) from the Mississippi River. The first documented specimen of C. asprella in Iowa was collected in Pool 11 of the Upper Mississippi River (UMR) in 1995. One specimen …

Tillage Effect On Soil Water Content And Soybean (Glycine Max) Yield In A Strip Intercropping System, M. Ghaffarzadeh, F. Garcia Prechac, M. M. Harbur, R. M. Cruse

Journal of the Iowa Academy of Science: JIAS

Soybean [Glycine max (L.) Merr.] response to strip-intercropping with corn (Zea may L.) and oat (Avena Jativa L.) interseeded with nondormant alfalfa (Medicago Jativa L.) may be affected by soil moisture. A three-crop strip-intercropping system of corn, soybean and oat interseeded with nondormant alfalfa was established to determine the effect of tillage system and row position on soil water content and grain yield in the soybean strip. The experiment was a split-plot design with three tillage treatments (conventional, CT; reduced, RT; and minimum tillage, MT) as main plot effects and three row positions (both edge rows and the center …
