Rural Depopulation In Western Australia, Ross Kingwell

Journal of the Department of Agriculture, Western Australia, Series 4

Western Australia's population has recently drifted from inland rural areas to cities and coastal regions. Changes in fanning practices over several decades and the recent falls in wheat and wool prices, have forced many families to leave inland farms and rural towns .

However, many families are also developing sources of off-farm income and other activities to keep themselves, local businesses and towns suroiving.

Natural History In Iowa: The Early Phases, David C. Glenn-Lewin, Thomas R. Rosburg

Journal of the Iowa Academy of Science: JIAS

Natural history in Iowa prior to the 20th Century can be conveniently arranged into 4 phases: Native American, before the Louisiana Purchase, between the Louisiana Purchase and about 1850, and after 1850. Native American natural history was extensive and had a distinctly spiritual character. Natural history was a component of European exploration up to the time of the Louisiana Purchase, but was not treated as a separate endeavor; the evidence from this period comes from the journals and diaries of early exploreres, fur traders and the like. Between the Louisiana Purchase and about 1850, natural history changed from its status …

The Specific Surface Area Values For Iowa Tills, Keith E. Schilling, Brian L. Gedlinske

Journal of the Iowa Academy of Science: JIAS

Specific surface area is a property used by earth scientists to estimate the proportion of expandable clay minerals in soils. In this study, specific surface area method is shown to compare favorably with standard clay mineralogical techniques in determining gross differences in expandable clay mineral content in tills. The results of over 100 measurements on till samples from Iowa indicate undifferentiated pre-Illinoian tills from southern and southwestern Iowa have the highest specific surface area values of Iowa tills (ranging from nearly 100 to greater than 150 m²/g) and Wisconsinan Dows Formation tills have the lowest average specific surface …

Mass Dependent Loss Of Resolution In Radially Inhomogeneous Exb Ion Traps, Mark A. Capron, Susan S. Haskin, Curtiss D. Hanson

Journal of the Iowa Academy of Science: JIAS

ExB ion traps, such as Fourier transform Ion Cyclotron Resonance mass spectrometers (FY:ICR), mass analyze sample ions based on differences in their cyclotron frequencies in a homogeneous magnetic field. The high resolution mass measurements of FT-ICR are based on the relationship between the frequency of the cyclotron orbit and the mass-to-charge (m/q) ratio of an ion. Both the orbit and the frequency/mass relationship result from the radial forces on the ion. Ions trapped by inhomogeneous electric fields experience different magnitudes of the radial electric fields at different positions resulting in a positionally dependent frequency. Such differences in orbital frequencies for …

Checklist Of The Vascular Flora Of Page County, Iowa, Barbara L. Wilson

Journal of the Iowa Academy of Science: JIAS

The vascular flora of Page County, Iowa, was studied from 1987 through 1991. Seven hundred forty two species and four hybrids of vascular plants were found. A quarter of the flora consists of non-native species. Taxa not previously reported in Iowa include: Amsinckia intermedia, Brassica kaber, Cardaria chalapensis, Callirhoe bushii, Carex mesochorea, Eleocharis xyridiformis, Euphorbia prostrata, Lactuca saligna, Leontodon autumnalis, Scirpus mucronatus, Sclerochloa dura, and Vernonia arkansana.

Changes In The Western Australian Dairy Farm Industry, Ross Kingwell, Graham Annan

Journal of the Department of Agriculture, Western Australia, Series 4

Over the past decade, the number of dairy cows and the number of producers in the Western Australian dairy industry have steadily declined. The industry still relies heavily on market milk quotas for its profits, but recent export contracts have boosted profits from manufacturing milk production.

Market milk quotas remain unevenly distributed across the dairy regions and amongst quotaholders, although the regional distribution of quotas is changing.

The Distribution Of Amphipods In Southeastern Minnesota And Their Relation To Water Quality And Land Use, James A. Muck, Raymond M. Newman

Journal of the Iowa Academy of Science: JIAS

The distribution of the amphipods Gammarus pseudolimnaeus and Hyalella azteca was determined from 97 designated trout streams in Minnesota, along with temperature, conductivity, and nitrate levels. Streams were classified into 4 land use/geology groups. G. pseudolimnaeus was found in 11 counties and at 123 of 168 sites in 83 of the 97 streams sampled. Hyalella azteca was found in 7 counties at 26 sites m 21 streams. Spearman rank correlations showed a high degree of correlation between nitrate (range: 0-11 mg N/L), conductivity (range: 325-870 μS/cm), and geology. The relative abundance of G. pseudolimnaeus was negatively correlated with nitrate, geology …

Geology Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii, R. G. Baker

Journal of the Iowa Academy of Science: JIAS

Fens are peatlands which are dependent on groundwater discharge to provide nutrient enrichment. Fens are found in a variety of landscape positions and in most Iowa landform regions. This paper presents a classification system for Iowa fens based on landscape position, stratigraphy, and hydrologic factors. Iowa fens can be separated into six categories: 1) fens along valley wall slopes; the groundwater source for these fens is sand and gravel buried between glacial tills (inter-till); 2) fens in hummocky topography on the northwestern margin of the Des Moines Lobe landform region; the water source is sand and gravel buried within glacial …

Necklace Radio Transmitter Attachment For Pheasants, Terry Z. Riley, Bruce A. Fistler

Journal of the Iowa Academy of Science: JIAS

We tested a pre-assembled, necklace-radio-transmitter-attachment design on female ring-necked pheasants (Phasianus colchicus) in northern Iowa. Birds were captured by nightlighting and bait trapping between September 1989 and March 1990. Radio transmitters were attached to 128 using a wire necklace. Two birds had problems adapting to the necklace, and 3 birds removed them. Twenty-three birds were still alive and wearing necklaces at the end of the study, for an average of 318 (SD= ± 52) days. Ease of attachment, long durability, light weight, and minimal bulk make the necklace an effective alternative to harness and poncho mounts.

History Of Iowa Natural History - A Symposium, Neil P. Bernstein

Journal of the Iowa Academy of Science: JIAS

This issue of the Journal of the Iowa Academy of Science presents the first written installment of our symposium: papers on the contributions of Keyes, Pammel, Bessey, and Hayden; the role of the Iowa Natural History Museum; and histories of both the development of early natural history studies and mammalogy investigations. More papers will follow in future issues, and new contributors are welcome.

History Of Mammal Study In Iowa, John B. Bowles

Journal of the Iowa Academy of Science: JIAS

The first records of mammals in Iowa were from explorers, survey parties heading westward and early seeders. Generation of checklists of state mammals began in 1840 and culminated with the annotated list by Scott (1937) and biogeographic analysis by Bowles (1975). Recent focus has been on rare species status and mammalian ecology, e.g., Loess Hills, riparian habitat, agricultural practices, and reestablished grasslands.

The University Of Iowa Museum Of Natural History: An Historical Perspective, George D. Shrimper

Journal of the Iowa Academy of Science: JIAS

The 132-year record of UIMNH essentially mirrors historical and on-going trends in related institutions. As scholarship grew in the natural sciences during the 19th century, natural history museums became centers for scientific research. A "Golden Age" of museum-based expeditionary work and taxonomic research was marked at UI by the careers of curator/naturalists Calvin, Nutting, Macbride, and Shimek. Systematic biology and paleontology thrived with the accumulation of extensive collections. De-emphasis of "natural history" studies followed after 1920-30 with a concomitant growth in cellular and molecular biology. In seeking new directions and financial support, many museums, including UIMNH, shifted emphasis to public …
