Geochemistry Of Buried Midcontinent Rift Volcanic Rocks In Iowa: Data From Well Samples, Karl E. Seifert, Raymond R. Anderson

Journal of the Iowa Academy of Science: JIAS

We analyzed welt cores and cuttings from deep wells into Precambrian igneous rocks from five separate pacts of the buried Midcontinent Rife System in Iowa for major and trace elements. A total of 21 samples, 9 cores and 12 cuttings, were analyzed for trace elements by instrumental neutron activation analysis (INAA) and 11 of these, 9 cores and 2 cuttings, were analyzed for major elements by inductively coupled plasma (ICP) analysis.

Book Review - The Unnatural Nature Of Science: Why Science Does Not Make (Common) Sense, David Lopatto

Journal of the Iowa Academy of Science: JIAS

A distinguished psychologist once wrote that if you wished to understand the history of scientific thought you need a psychologist at your elbow. Lewis Wolpert, Professor of Biology at University College in London, has taken that sentiment further. It seems that if you wish to understand the difference between scientific and nonscientific thinking you should delve deeply into the literature of cognitive psychology. For natural thinking, "ordinary, day-to-day common sense will never give an understanding about the nature of science." Instead, the trained scientist engages in unnatural (i.e., counterintuitive) thinking about a word that defies ordinary experience. In order to …

Crossroads, Milestones, Amd Landmarks In Insect Development And Evolution: Implications For Systematics, Rob Desalle, Donat Agosti, Michael Whiting, Beatriz Perez-Sweeney, James Remsen, Rick Baker, James Bonacum, Ranhy Bang

Aliso: A Journal of Systematic and Floristic Botany

Our understanding of insect development and evolution has increased greatly due to recent advances in the comparative developmental approach. Modem developmental biology techniques such as in situ hybridization and molecular analysis of developmentally important genes and gene families have greatly facilitated these advances. The role of the comparative developmental approach in insect systematics is explored in this paper and we suggest two important applications of the approach to insect systematics--character dissection and morphologicallandmarking. Exi~ng morphological characters can be dissected into their genetic and molecular components in some cases and this will lead to more and richer character information in systematic …

Bald Eagles Wintering Along The Des Moines River, Iowa, Neil Sabine

Journal of the Iowa Academy of Science: JIAS

Distribution, habitat use, and foraging behavior of Bald Eagles (Haliaeetus leucocephalus) wintering in southeast Iowa were studied in January - March 1990 and November 1990 - March 1991. Eagles were seen from November through March with the highest numbers in January and February. Adults had shorter winter residence times than immatures and they appeared to be less active during the day. Eagles concentrated their foraging efforts along certain river segments where they fed exclusively on fish. Timber harvesting along the river reduced eagle use and is considered to be the most serious threat to sustaining eagle use of the area. …

Life History And Status Classifications Of Birds Breeding In Iowa, Louis B. Best, Kathryn E. Freemark, Barbara S. Steiner, Timothy M. Bergin

Journal of the Iowa Academy of Science: JIAS

Life history and status classifications were compiled for 145 bird species that breed in Iowa. Species were classified by food type and substrate, nest substrate, susceptibility to cowbird parasitism, migratory status, predominant habitat use and habitat-use specialization, body mass (an index of home range/territory size), area sensitivity, population trend and vulnerability, and beneficial/harmful aspects in relation to agriculture. Such information may be used to make interspecific comparisons, evaluate interrelationships among life history and status characteristics, and provide insights into the interpretation of previous research. This synthesis also can aid those responsible for making conservation and management decisions about Iowa's avifauna.

The Natural History Of Aconitum Noveboracense Gray (Northern Monkshood), A Federally Threatened Species, Margaret A. Kuchenreuther

Journal of the Iowa Academy of Science: JIAS

Aconitum noveboracense Gray (Ranunculaceae), commonly known as northern monkshood, is a federally threatened herbaceous perennial that occurs in disjunct populations in Iowa, Wisconsin, Ohio and New York. It appears to be a glacial relict, existing today only in unique areas with cool, moist microenvironments, such as algific talus slopes. Field studies reveal that A. noveboracense has a complex life history. Perennation of individual plants occurs through the annual production of daughter tubers. Vegetative reproduction is commonly observed, and can occur by means of aerial and subterranean bulbils, as well as by development of adventitious root buds. Populations also reproduce sexually …

1 | The Akeldama Tombs: Three Burial Caves In The Kidron Valley, Jerusalem, Gideon Avni, Zvi Greenhut

IAA Reports—Monograph Series of the Israel Antiquities Authority

The Kidron Valley was one of the main burial grounds of First Temple-period Jerusalem, and numerous tombs were also hewn here during the Second Temple period. During road works in the valley, three large, elaborate Second Temple-period tombs were exposed, which contained an abundance of rich and intact finds, some still in situ, including pottery, glass, jewelry, a sarcophagus and many ossuaries, some inscribed. The finds also provided evidence that the tombs were reused during the Roman and Byzantine periods. This volume describes the architecture, burial customs, finds and chronology, as well as an analysis of the bones from …

Analytical Perspectives On A Protohistoric Cache Of Ceramic Jars From The Lower Colorado Desert, James M. Bayman, Richard H. Hevly, Boma Johnson, Karl J. Reinhard, Richard Ryan

Karl Reinhard Publications

A cache of hermetically sealed ceramic jars found in the Lower Colorado Desert was examined using chronometric dating, pollen and macrofossil extraction, design analysis, and water retention experimentation. The cache apparently dates to the protohistoricfifteenth through seventeenth centuries. Findings from these studies contribute to knowledge in four problem areas: (1) ceramic jar function and use-history; (2) storage technology and caching behavior; (3) ceramic dating and chronology; and (4) symbolic iconography. Biotic remains from inside the jars document their use for transporting a variety of riverine and desert plants, before they were finally filled with flowers and seeds, and placed in …

Biological Determinism And The Human Genome Project: Is The Past Prologue?, Alexandra Dawn Breen

Theses & Honors Papers

In 1989, The National Institutes of Health, in collaboration with the United States Department of Energy, launched a three billion dollar project that could potentially change the way we view human life. The purpose of the project is to map every gene on every chromosome of the human DNA. The Human Genome Project, as it is referred to, is scheduled for completion by the year 2005. The frank reality of the Human Genome Project is that it will indeed offer some real and measurable benefit to different types of people, including some of those inflicted with fatal diseases and disorders; …

Enamel Prism Morphology In Molar Teeth Of Small Eutherian Mammals, Elizabeth R. Dumont

Scanning Microscopy

Data summarizing enamel prism shape, sire and spacing are reported for the molar enamel of 55 species of small eutherian mammals including primates, bats, tree shrews, flying lemurs, insectivorans and representatives of a variety of fossil families. Confocal photomicrographs reveal that the subsurface enamel of most species is characterized by arc-shaped prisms. The lack of a clear distinction between pattern 2 and pattern 3 prism configurations within single specimens suggests that the broad category "arc-shaped prisms" is the most appropriate descriptive grouping for these species. Of the total sample, three species exhibit only circular prisms while no evidence of prismatic …

Evaluation Of Animal Welfare By The Self-Expression Of An Anxiety State, M. P. Carey, J. P. Fry

Assessment of Animal Welfare Collection

Although mental well-being has long been accepted as an important aspect of animal welfare, the subjective feelings of farm or laboratory animals are regarded as lying beyond the scope of scientific enquiry. We now report that pharmacological conditioning of pigs with a drug, pentylenetetrazole, known to induce anxiety in man, permits investigation of the presence or absence of this psychological state during exposure to a variety of environmental stimuli encountered during normal husbandry. Such pharmacological conditioning therefore provides a valuable means to assess and improve elements of animal welfare and should be applicable to other species that show operant behaviour.

Mammalian Enamel Prism Patterns And Enamel Deposition Rates, Elizabeth R. Dumont

Scanning Microscopy

Enamel prism patterns and enamel deposition rates were compared for specimens representing six mammalian orders. Enamel samples were characterized by either pattern 1 or pattern 3 prisms. Each prism pattern cate-gory contained prisms from at least two mammalian orders. Enamel deposition rate was estimated for each sample by measuring prism cross striation repeat intervals. Statistical analysis of cross striation repeat intervals illustrates significant differences in deposition rate between prism patterns 1 and 3. No statistically significant differences were found in deposition rate between the higher-level taxa represented within each prism pat-tern category. That enamel deposition rate is not taxon-specific reinforces …
