Review Of Cheyenne Bottoms: Wetland In Jeopardy By John L. Zimmerman, John Janovy

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The Cheyenne Bottoms, Barton County, Kansas, has long been hallowed ground for birders and scientists as well as hunters. The dikes let one drive slowly through the marshes, scanning the flats for favorite sandpiper species and experiencing first hand the isolation of the central Kansas prairies. John Zimmerman, professor of biology at Kansas State University, had captured the Cheyenne Bottoms aura in eloquent prose, giving us a taste of wetlands natural history, while bringing to life the political and economic conflicts surrounding Arkansas River, and Walnut Creek, water. In many ways, the Cheyenne Bottoms case is a modern archetypical prairie …

Review Of Sociobiology And The Social Sciences By Robert W. Bell And Nancy J. Bell, David R. Johnson

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The application of evolutionary theory of inclusive fitness to understanding human social behavior has seen a recent resurgence in anthropology, psychology, and sociology. While sociobiological theory and research are still incipient In these disciplines, the perspective has received enough attention to warrant all social scientists becoming more acquainted with the theory and methods of the practicing sociobiologist. The title and modest size of this book (only 130 pages) suggest that it might serve well for this purpose. It contains seven original papers by practicing sociobiologists written for an audience not well versed in the evolutionary model. While terms are carefully …

Review Of The Bats Of Texas By David J. Schmidley, Patricia W. Freeman

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

There are few "Bats of” books for states because usually there are not that many species located in a particular state and second, we often do not have much information about the bats in a particular place or state. But there has been increasing interest in bats in the last few years stimulated by organizations like Bat Conservation International and publications like Bats of Carlsbad Caverns, both of which have high quality photographs of bats. The Carlsbad publication has particularly spectacular pictures of bats in flight.

Temporal And Spatial Dietary Variability In The Prehistoric Lower And Middle Osmore Drainage: The Carbon And Nitrogen Isotope Evidence, Karin L. Sandness

Department of Anthropology: Theses and Student Research

Skeletal material from six sites representing human occupation in the Osmore drainage of southern Peru, circa A.D. 50 to 1400, was analyzed for carbon and nitrogen isotopes. The δ¹³C and δ¹⁵N values observed in the study indicate-spatial and temporal variability in diet. Specimens from the lower valley are, in general, more positive in both carbon and nitrogen than those of the middle valley, with the most positive values being present in specimens from the coastal Chiribaya site, San Geronimo. The data suggest, however, that all populations in the drainage experienced shifts in diet through time. Samples …

Assessing Needs For Computer Pest Management Software In Nebraska Agriculture, Robert J. Wright

Department of Entomology: Faculty Publications

A mail survey was conducted to assess current computer hardware use and perceived needs of potential users for software related to crop pest management in Nebraska. Surveys were sent to University of Nebraska-Lincoln agricultural extension agents, agribusiness personnel (including independent crop consultants), and crop producers identified by extension agents as computer users. There were no differences between the groups in several aspects of computer hardware use (percentage computer use, percentage IBM-compatible computer, amount of RAM memory, percentage with hard drive, hard drive size, or monitor graphics capability). Responses were similar among the three groups in several areas that are important …

Beginning Of Motion For Selected Unanchored Residue Materials, John E. Gilley, Eugene R. Kottwitz

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Conservation tillage systems help to maintain residue materials from the previous crop on the soil surface. The potential for serious erosion may exist if crop residues are removed by overland flow. This study is conducted to identify the hydraulic conditions required to initiate residue movement by overland flow. Corn, cotton, peanut, pine needles, sorghum, sunflower, and wheat residue are placed in a flume on smooth and sand surfaces, and flow is then introduced in progressive increments. The discharge rate and flow velocity required to initiate residue movement are identified. Hydraulic measurements are used to calculate the ratio of critical flow …

The Roles Of Ecological And Evolutionary Influences In Providing Structure To Parasite Species Assemblages, John J. Janovy Jr., Richard E. Clopton, Tamara J. Percival Cook

John J. Janovy, Jr. Publications

Parasite species assemblages currently are thought to range from isolationist to interactive, their dynamic properties being related to the number of species and types of hosts involved. The literature contains few experimental tests of this concept, however, and many of the host/parasite systems studied to date are not amenable to experimental manipulation. In this review, the presence of a parasite species, in a sample of host individuals, is considered to be an evolutionary phenomenon, but the parasite's population structure is considered to be an ecological one. Studies that allow evaluation of these two influences are comparative in nature and include …

Lipoxygenase Inhibitors Shift The Yeast/Mycelium Dimorphism In Ceratocystis Ulmi, Ellen C. Jensen, Clyde Ogg, Kenneth W. Nickerson

Papers in Microbiology

The yeast-mycelium dimorphism in Ceratocystis ulmi, the causative agent of Dutch elm disease, was switched by gossypol, nordihydroguaiaretic acid, and propylgallate. In each case the mycelial form was converted to the yeast form. These compounds are recognized lipoxygenase inhibitors. Inhibitors of cyclooxygenase and thromboxane synthetase did not cause mycelia to shift to the yeast form. We suggest the following two-part hypothesis: (i) that lipoxygenase is a target for antifungal antibiotics and (ii) that many phytoalexins (antimicrobial compounds of plant origin) are targeted toward fungal lipoxygenases. In addition, in a study to determine potential lipoxygenase substrates, a fatty acid analysis …

Parasites As Probes For Biodiversity, Scott Lyell Gardner, Mariel L. Campbell

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cestodes of the genus Linstowia, parasitic in marsupials, show patterns of coevolution and ancient historical-ecological connections. Correlated with the breakup of the austral landmasses (Gondwanaland) of the Neotropical and Australian regions from the Antarctic continent, the age of this host-parasite community is estimated to be between 60 and 70 million years old. Based on the data from the survey of parasites of mammals from throughout Bolivia and from the phylogenetic analysis of the cestodes, we urge the planners of biodiversity preserves in the neotropics to consider the Yungas of Bolivia as a region that supports an ancient ecological community …

Origins, Diversification, And Historical Structure Of The Helminth Fauna Inhabiting Neotropical Freshwater Stingrays (Potamotrygonidae), Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Members of the freshwater stingray family Potamotrygonidae occur throughout the major river systems of eastern South America that empty into the Atlantic Ocean. Ichthyologists have tended to assume that the ancestor of the potamotrygonids was an Atlantic marine or euryhaline stingray that dispersed into freshwater, presumably during the last marine ingression 3-5 million years ago. The helminth parasites that inhabit potamotrygonids suggest an alternative perspective on their origin. Phylogenetic and biogeographic analysis of the helminths inhabiting potamotrygonids suggest that the hosts are derived from an ancestral Pacific urolophid stingray that was trapped in freshwater by the uplifting of the Andes …

Parasiticidal Effect Of Chemotherapy In Alveolar Hydatid Disease: Review Of Experience With Mebendazole And Albendazole In Alaskan Eskimos, J. F. Wilson, Robert L. Rausch, B. J. Mcmahon, P. M. Schantz

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Evidence that the larval stage of Echinococcus multilocularis in humans is killed by chemotherapy is presented in a review of our 17-year experience with treatment of alveolar hydatid disease in Alaska. The efficacy of chemotherapy was assessed with use of an in vivo assay of parasite viability by means of inoculation of voles, immunohistochemical tests, and histopathologic findings. Of 14 tests performed for nine patients, 12 in vivo assays (86%) were negative after chemotherapy, while only two (17%) of 12 vole tests for seven untreated patients were negative. Regression or arrest of growth of metastatic and primary hepatic lesions, together …

Congruent And Synchronic Patterns In Biogeography And Speciation Among Seabirds, Pinnipeds, And Cestodes, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Congruence in biogeographic patterns among diverse assemblages of taxa indicates uniformity in the historical determinants of biotic distributions. Comparisons of host and parasite phylogenies and the elucidation of distributional area relationships are requisite components of analyses in historical biogeography. Host-parasite associations with broad geographic ranges are often archaic and have been structured largely by coevolutionary processes. In contrast, the origins and radiation of the primary cestode faunas of some seabirds (Alcataenia spp./Alcidae) and pinnipeds (Anophryocephalus spp./Phocidae and Otariidae) are associated with colonization. These young colonizing faunas, in the Holarctic Region, were influenced by a common history during the …

In Vitro Development Of Zygotes From Prepubertal Gilts After Microinjection Of Dna, B. L. Williams, J. L. Johnson, A. E.T. Sparks, R. S. Canseco, J. W. Knight, William H. Velander, R. L. Page, W. N. Drohan, J. M. Young, R. E. Pearson, T. D. Wilkins, F. C. Gwazdauskas

Papers in Biotechnology

The effect of pronuclear microinjection of DNA and culture in excised mouse oviducts on the development of porcine zygotes was assessed in this study. Precocious ovulation was induced in prepubertal gilts with pregnant mare's serum gonadotrophin and hCG. Zygotes received either pronuclear microinjection of buffer alone, buffer containing a DNA construct, or no microinjection. Zygotes were cultured in vitro in either modified Krebs-Ringer bicarbonate medium (KRBI for 144 h or in mouse oviduct (MO) explant culture with KRB for 48, 72, 96, or 120 h. Pronuclear microinjection of DNA resulted in a lower (P < .05) cleavage index (CII than did buffer or no microinjection (CI 2.16 k .10 vs 2.80 f .13 and 2.93 f .lo). The CI loss was greatest for DNA-injected zygotes at the two-cell stage of development. Coculture of zygotes in MO resulted in a higher CI (P < .01) than did culture in KRB. Culture in MO for 72 h was the most beneficial system compared with MO for 48, 96, or 120 h (P < .05; CI 3.25 k .12 vs 2.66 k .18, 2.79 f .14, and 2.40 .14, respectively). Microinjection of DNA, not merely the mechanical procedure, was detrimental to early zygote development and may be the cause of low pregnancy rates.

Three-Dimensional Solution Structure Of Human Interleukin-4 By Multidimensional Heteronuclear Magnetic Resonance Spectroscopy, Robert Powers, Daniel S. Garrett, Carl J. March, Eric A. Frieden, Angela M. Gronenborn, G. Marius Clore

Department of Chemistry: Faculty Publications

The three-dimensional solution structure of recombinant human interleukin-4, a protein of 133 residues and 15.4 kilodaltons that plays a key role in the immune and inflammatory systems, has been solved by multidimensional heteronuclear magnetic resonance spectroscopy. The structure is dominated by a left-handed four-helix bundle with an unusual topology comprising two overhand connections. The linker elements between the helices are formed by either long loops, small helical turns, or short strands. The overall topology is remarkably similar to that of growth hormone and granulocyte-macrophage colony stimulating factor, despite the absence of any sequence homology, and substantial differences in the relative …

Review Of 'My Way To Ornithology' By Olin Pettingill, Jr., Paul A, Johnsgard

Nebraska Bird Review

Most Nebraskans who recognize this author's name probably will remember him as a cinematographer and lecturer in the Audubon Screen Tour series. The series was a regular part of live entertainment in Lincoln and Omaha until the early 1960s.

Other bird-oriented people will know that Pettingill wrote two of the first and still best regional bird-finding books (detailed guidebooks to bird-finding localities in the states east and west of the Mississippi, respectively). Perhaps still others will remember him as a one-time teacher of ornithology at Carleton College and the University of Michigan Biological Station, or as a director of the …

Book Review: Genetically Engineered Organisms: Benefits And Risks, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

In the continuing debate on the introduction into the environment of genetically modified organisms, particularly those modified by recombinant DNA, there are few books suitably written for policymakers, the lay public and scientists in other fields. This book describes the current state of the science and art of genetic engineering, potential uses (particularly outside the laboratory), and the benefits that can be expected. It is particularly pertinent for examining potential risk and management of risk from the perspective of the United Kingdom.
