Evolution Of The Aeluroid Carnivora: Significance Of The Ventral Promontorial Process Of The Petrosal, And The Origin Of Basicranial Patterns In The Living Families, Robert M. Hunt Jr.

Department of Earth and Atmospheric Sciences: Faculty Publications

In studies of carnivoran phylogeny, the configuration and ontogenetic development of the auditory bulla enclosing the middle ear have been useful in tracing modern lineages to their first appearances in the mid-Cenozoic. Pre-Oligocene carnivorans, however, lack preserved bullae and have been difficult to relate to later Cenozoic groups. The carnivoran petrosal bone, because of its durability both in intact skulls and as an isolated element, can be tracked through Cenozoic time, and can supply new information on lineage continuity through its geometry and spatial relationships. Aeluroid carnivorans are united by a petrosal of characteristic shape, distinguished by a ventral promontorial …

Executive Summary

Biological diversity refers to the variety and variability among living organisms and the ecological complexes in which they occur. Diversity can be defined as the number of different items and their relative frequency. For biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular basis of heredity. Thus, the term encompasses different ecosystems, species, genes, and their relative abundance (OTA, 1987).

There is an ongoing, unprecedented loss of the variety as well as absolute numbers of organisms-from the smallest microorganism to the largest and most spectacular of …

Enhancing The Adoption Of Soil Conservation Practices With Targeted Educational Programs, David P. Shelton, Elbert C. Dickey, Paul J. Jasa, David A. Biere

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Two independent, but closely related, grant funded educational programs have been developed and implemented to reduce soil erosion in selected areas of eastern Nebraska, U.S.A. Traditional extension programming methods as well as other more nontraditional approaches have been extensively used. In one program, encompassing 220,000 ha of cropland, annual soil erosion has been reduced by 2.5 Mt and annual fuel savings of 1.5 ML have been achieved through a reduction in the number of tillage operations. During a one-year period in the second project, more than 81,000 m of terraces were constructed, which resulted in an annual soil erosion reduction …

Toward A Resolution Of The Paradox Of Aggressive Displays: Ii. Behavioral Efference And The Communication Of Intentions, Alan B. Bond

Papers in Behavior in Biological Sciences

An inference from game-theory models of animal conflict is that adversaries should not inform one another about their level of aggressive motivation. This poses a paradox for the traditional ethological account of graded aggressive displays because it is usually assumed that the adaptive significance of these behavior patterns lies in their making such information available. To resolve the paradox, I propose that communication is only an incidental effect of displays, and that their primary adaptive function is regulation of the intensity of aggressive encounters through positive feedback on aggressive motivation, a process termed "behavioral efference." Evidence in support of this …

Trichome Development In Arabidopsis Thaliana. 1. T-Dna Tagging Of The Glabrous1 Gene, M. David Marks, Kenneth A. Feldmann

School of Biological Sciences: Faculty Publications

Progeny from a transformed Arabidopsis plant (produced by the Agrobacterium-mediated seed transformation procedure) were found to be segregating for an altered trichome phenotype. The mutant plants have normal leaf trichomes but completely lack trichomes usually found on the stem. The mutation is tightly linked to a T-DNA insert. Complementation analysis with genetically characterized trichome mutants revealed that the new mutation is an allele of the GL1 locus. The new trichome mutant has been designated gl1-43. DNA gel blot analysis indicated that the insert site contains a complex array of at least four tandemly linked T-DNA units oriented as both …

The purpose of this study was to identify agribusiness skills required by a student for entry level employment in Nebraska agribusinesses. The specific objectives were:

1. To determine agribusiness skills perceived to be required for employment, by Nebraska agribusiness managers and vocational agriculture instructors,
2. To determine differences between the perceived importance of selected skills required for employment in an agribusiness, by Nebraska vocational agriculture instructors and agribusiness managers.

The Presentation Of The City On ‘Fat-Letter’ Postcards, Mary Jo Deegan, Michael R. Hill

Department of Sociology: Faculty Publications

Media-constructed rituals are cultural products. Unlike participatory rituals, my focus thus far, media-constructed rituals have more stability, higher internal order and consistency, and greater potential to reach people over time. Cultural artifacts from the past can reach people in their own era, the present, and the future, and in this way they provide a source of continuity even for rapidly changing societies. We begin this section of the book by examining a small artifact in an interaction ritual, the presentation of the city on a particular style of postcard.

Cities are complex human environments that are frequently symbolized in the …

Variable Angle Spectroscopic Magneto-Optics And Ellipsometry: Application To Dyco Multilayers, Thomas E. Tiwald, William A. Mcgahan, Z. S. Shan, Alan M. Massengale, John A. Woollam

Department of Electrical and Computer Engineering: Faculty Publications

The purpose of this paper is twofold. First, we describe the adaptation of a variable angle spectroscopic ellipsometer (VASE) to magneto-optic measurements covering 3000–8000 Å, and 0 to ±8 kOe. Second, we describe application of VASE to determine Kerr rotation and ellipticity for a series of Dy/Co multilayers prepared by sputter deposition. We report spectroscopic ellipsometric and Kerr effect results for samples exhibiting perpendicular magnetic anisotropy, since these are relevant as magneto-optic recording media.

Identification Of Learning Styles Strategies Which Enable College Students With Differing Personality Temperaments To Cope With Learning Blocks, Gholam Hossein Zamani Zarghani

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

The purpose of this study was to identify the major coping strategies which college students with different personality temperament used to deal with their learning blocks. Students' temperament type was obtained from the pool of the Myers-Briggs Type Indicator results available at the Agricultural College, UN-L. An instrument measuring learning blocks was designed and administered in the Fall, 1987. The Coping strategy Inventory (CSI) was developed and administered in the spring, 1988. One hundred and twenty seven agricultural college students responded to the first phase of the study, and 230 agricultural college students took the CSI. The Statistical package for …

Isolation And Characterization Of Monoclonal Antibodies Directed Against Plant Plasma Membrane And Cell Wall Epitopes: Identification Of A Monoclonal Antibody That Recognizes Extensin And Analysis Of The Process Of Epitope Biosynthesis In Plant Tissues And Cell Cultures, David J. Meyer, Claudio L. Alfonso, David W. Galbraith

Papers in Microbiology

Membranes from tobacco cell suspension cultures were used as antigens for the preparation of monoclonal antibodies. Use of solid phase and indirect immunofluorescence assays led to the identification of hybridomas producing antibodies directed against cell surface epitopes. One of these monoclonal antibodies (ll.D2) was found to recognize a molecular species which on two-dimensional analysis (using nonequilibrium pH-gradient electrophoresis and SDS-PAGE) was found to have a high and polydisperse molecular mass and a very basic isoelectric point. This component was conspicuously labeled by [3H]proline in vivo. The monoclonal antibody cross-reacted with authentic tomato extensin, but not with potato lectin nor larch …

Entrepreneurs And Private Enterprise: The Development Of Medical Lecturing In London, 1775–1820, Susan C. Lawrence

Department of History: Faculty Publications

Beginning in the 1730s and 1740s, "market forces" tempered by professional and institutional constraints shaped the growth and organization of medical teaching in London. Gradually, after 1815, the growing protectionism of the licensing corporations undercut the private entrepreneur and, by the middle of the nineteenth century, led to the ascendancy of organized medical schools and university-granted medical degrees.

Recent work on eighteenth-century medicine has begun to focus attention on London as a dynamic center for both practical clinical experience and formal lecturing. Such current research has, however, primarily concentrated on a few significant individuals, especially William and John Hunter and …

The Pest Control Industry And The Challenges Ahead , Lee C. Truman

Vertebrate Pest Conference Proceedings: 13th (1988)

The pest control industry, whether it be governmental, urban, aerial, lawn and turf, trees, or whatever, has many of the same problems. Controllers of vertebrate or invertebrate pests, or plant pests, have much in common. Environmental¬ists talk of the "balance of nature," usually overlooking the fact that nature is more often out of balance than in balance. Nature is cruel in its control of plant and animal species whenever there is not enough food to go around or enough of a suitable habitat in which to live. Nature does not conserve things as they are but, rather, changes them and …

Pesticides, Scientists, Farmers, And The Public: No "White Knight" Rescue In Sight, Pamela Jones

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: The pesticide controversy is much more complicated than simply a disagreement over facts and risk estimates between the "experts" and the "fearful." It is a battle over ideology as much as one over information. This paper discusses the notion of "educating the public" about pesticides, establishing realistic expectations of efforts by industry and academia, and notes some of the limitations, and potential involvement, of scientists as "translators" in dealing with this controversy.

Animal Rights And Vertebrate Pest Control, Dale L. Brooks

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Many animal rights activists are very vocal in their belief that animals are more valuable or at least equally important to humans. There is little to no compromise in their overall view that the use of animals for food, fiber, teaching, research and testing does not result in improvements for other animals or societal needs. Today's activists are well prepared and very articulate in getting their views across to the public through the press and television media. An increasing number of the public is beginning to believe the activist allegations of inhumane animal practices. The biologist can no longer …

Vertebrate Pesticides And Nontarget Wildlife Losses In Proper Perspective, James E. Miller

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: The use of pesticides as one of the management tools to assist in the prevention and control of damage caused by vertebrate wildlife is certainly not new, nor has it become any less controversial in recent years. In fact, throughout the recent history of pesticide uses for control of vertebrate damage to the production of food and fiber, the prevention of potential epizootic diseases, and other potential threats to man's well-being and to the habitats and management of other wildlife resources, the use of pesticides as well as other management tools have generally been reviewed and monitored by professionals. …

Photonovels Produced By Client/Professional Partnerships: An Educational Approach To Commensal Vertebrate Ipm, Stephen C. Frantz, John P. Comings, Debra L. Roter

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Since commensal vertebrate pest problems are largely "people problems," a well-planned and executed educational intervention could be the single most important component in an integrated pest management (IPM) program. The basic purpose of educational interventions is to bring sufficient information and understanding to affected clients so that they can and will intercept and control pests in the infested habitat. The encouragement of client participation in producing educational materials is consistent with learning theory and pest management principles. Such production methods allow materials to be closely aligned with client concerns and establish a climate for mutual exchange of ideas between …

Solutions To Urban Bird Problems, William D. Fitzwater

Vertebrate Pest Conference Proceedings: 13th (1988)

A survey of municipalities across the country indicated that pigeons were the most widespread aerial nuisance in urban areas. These were followed in order by: blackbirds, starlings, house sparrows, woodpeckers, crows/ravens, swallows/swifts, waterfowl (Canadian geese, mallards, and coots), and gulls. With somewhat lesser frequency were robins, vultures, raptors, herons/egrets, mockingbirds, waxwings, and monk parakeets. Local bird problems were mostly handled by: USDA-APH1S-ADC, Health Department, City/County Animal Control, Landowner/householder, PCO, State Wildlife Agency, Police Department, and Mayor's office.

The Impact Of Wildlife Damage On Wildlife Management Programs In Wisconsin, Scott R. Craven

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Wildlife damage caused by species normally managed as game animals or furbearers should be of major concern to wildlife managers and various user groups: hunters, trappers, and other outdoor recreationists. Real or potential damage may be used as an important factor in determining population levels, harvest goals, and distribution of white-tailed deer and Canada geese in Wisconsin. In any state where private land and agriculture are important, such a strategy could reduce wildlife populations and associated recreational opportunities. Recent surveys in Wisconsin have quantified the amount and distribution of deer, goose, and turkey damage in Wisconsin. These data allow …
