Evaluation Of Passive Integrated Transponders As A Marking Technique For Turkey Poults, Dewaine H. Jackson, William H. Bunger Jan 1993

Evaluation Of Passive Integrated Transponders As A Marking Technique For Turkey Poults, Dewaine H. Jackson, William H. Bunger

Journal of the Iowa Academy of Science: JIAS

Injectable, passive integrated transponders (PITs) were evaluated as a marking technique for newly hatched wild turkey (Meleagris gallopavo Linnaeus) poults. Seven of 12, 3-day-old domestic turkey poults received a PIT implant and a wing tag. A control group of five poults received only a wing tag. Two subcutaneous implant sites were evaluated, along the right side of the neck and in the area between the right inner thigh and breast. One of7 PITs failed or was expelled during the first week. Four scanning errors, in which the PIT was present yet not detected during the initial scanning attempt, occurred in …


Range Expansion Of The Great-Tailed Grackle In The 1900s, James J. Dinsmore, Stephen J. Dinsmore Jan 1993

Range Expansion Of The Great-Tailed Grackle In The 1900s, James J. Dinsmore, Stephen J. Dinsmore

Journal of the Iowa Academy of Science: JIAS

In 1900, the range of the Great-tailed Grackle extended north of the Mexican border only into Texas. Since then, it has expanded its range greatly. It now nests in 14 states and has strayed to an additional eight states and three Canadian provinces. Much of this expansion has occurred since 1960. Great-tails often stray far from their normal range, especially in spring. Most of these strays are single individuals. In states where they have nested, breeding birds typically reach the state a few years after the first reports of the species. Great-tailed Grackles do well in a variety of human …

Mutant Weeds Of Iowa: V. S-Triazine Resistant Setaria Faberi Herrm, R. Thornhill, J. Dekker Jan 1993

Mutant Weeds Of Iowa: V. S-Triazine Resistant Setaria Faberi Herrm, R. Thornhill, J. Dekker

Journal of the Iowa Academy of Science: JIAS

S-triazine resistance in giant foxtail (Setaria faberi Herrm.) has been reported previously, but not in the midwestern U.S. corn belt or Iowa. A study was conducted using a chlorophyll fluorescence assay to confirm the presence of resistance in one S. faberi population in Iowa. Variable chlorophyll fluorescence assays confirmed that a population of this species with this type of resistance exists in Iowa. This is the first report of s-triazine resistance in S. faberi, and the fourth species with this type of herbicide resistance, found in an Iowa agroecosystem.

A Gravity Investigation Of The Fayette Structural Zone And Surrounding Area, Northeast Iowa, Richard L. Kellogg, Christopher Meinen Jan 1993

A Gravity Investigation Of The Fayette Structural Zone And Surrounding Area, Northeast Iowa, Richard L. Kellogg, Christopher Meinen

Journal of the Iowa Academy of Science: JIAS

A gravity survey was conducted over approximately 2600 square kilometers of northeast Iowa. The survey was undertaken to provide detailed gravity coverage at approximately one mile intervals and to investigate the sources of gravity anomalies in the study area. An additional objective was to verify with gravity data the presence of the Fayette Structural Zone, previously identified on the basis of magnetic linears. Four hundred and twenty-seven gravity stations were occupied and data from these stations combined with extant data from the Geological Survey Bureau of the Iowa Department of Natural Resources to produce the gravity interpretation. A Bouger gravity …

Advances In Biomolecule Analysis: Ftms Of Macromolecules, Curtiss D. Hanson, Ira M. Simet, Suzanne R. Smith Jan 1993

Advances In Biomolecule Analysis: Ftms Of Macromolecules, Curtiss D. Hanson, Ira M. Simet, Suzanne R. Smith

Journal of the Iowa Academy of Science: JIAS

The development of Fourier transform ion cyclotron resonance (FT-ICR) as an analytical technique has opened new avenues to the analysis of high molecular weight biomolecules. Because mass analysis is based on a detection of a frequency, it is possible to obtain high resolution mass measurements without sacrificing sensitivity. The unique ability to analyze high mass ions is based in the design of a passive ExB ion trap. Although in the past, field inhomogeneities have limited this technique, recent developments in both trap designs and excitation techniques have resulted in major improvements in both sensitivity and resolution.
