Estimation Of Components Of Variance By Method 3 And Henderson's New Method, G. F. S. Hudson, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

An algorithm for Method 3 for estimation of components of variance in a mixed model including fixed herd-year-season, genetic groups, and random sires nested within groups is presented. Computational aspects of the algorithm are discussed and compared with those of a new method of Henderson's. The new method involves equating quadratic forms based on approximate best linear unbiased prediction solutions to their expected values. Relative computing effort for the two methods depended on the ease of eliminating equations for fixed effects and on the number of traits. Numerical estimates from the two methods were similar. When the Method 3 estimate …

Black Elk Speaks As Epic And Ritual Attempt To Reverse History, Paul A. Olson

Department of English: Faculty Publications

Modern Siouan storytellers make a distinction in speaking of the difference between bedtime and sacred stories. Moreover, Lakota masters of the sacred arts are inveterate constructors of figural or allegorical systems. They interpret, apply, and reapply the iconological resources of their culture through ritual, myth, storytelling, symbolic action, and clothing. This Sioux symbolic tradition is one context in which John G. Neihardt's Black Elk Speaks (1932) must be understood. Conceptualizing it as an epic may assist both Western and non-Western readers to clarify the uses to which a culture's symbol system may be put in mediating conflicting values, especially those …

Wildlife Values Versus Human Recreation: Ruby Lake National Wildlife Refuge, Stephen H. Bouffard

United States Fish and Wildlife Service: Publications

Expanding human populations are making increased recreational demands on National Wildlife Refuges (NWR). The U.S Fish and Wildlife Service (FWS) is trying to accommodate these demands whenever possible. An important, but not primary objective of NWRs is to provide for various public uses, including recreation (U .S. Fish and Wildlife Service 1976a). The Refuge Recreation Act of 1962 (16 U.S.C. 460K-460K-4) authorizes the FWS to allow recreational uses on NWRs, National Fish Hatcheries and similar lands. This act specifies that all recreational uses must be secondary to the primary purpose of the refuge. While most refuge recreation programs do not …

Habitat Models For Land-Use Planning: Assumptions And Strategies For Development, Adrian H. Farmer, Michael J. Armbruster, James W. Terrell, Richard L. Schroeder

United States Fish and Wildlife Service: Publications

Wildlife managers have long recognized that management goals must be constrained by the availability and suitability of habitat. This recognition, combined with ever increasing land development pressures, has resulted in environmental legislation emphasizing systematic approaches to collection and analysis of habitat information. Wildlife planners have responded with a variety of approaches to the development of models that quantify habitat requirements.

Interactions Of Northern Fur Seals And Commercial Fisheries, Charles W. Fowler

United States Department of Commerce: Staff Publications

Under international agreement, the northern fur seal (Callorhinus ursinus) is managed with the objective of obtaining a maximum sustainable yield. Currently the harvest is restricted to subadult males; however, between 1956 and 1968 the fur seal population of the Pribilof Islands was subjected to a harvest of females. This harvest was justified, in part, as an attempt to stimulate the production of greater quantities of harvestable animals (Chapman 1981). A reduction in the population occurred during this period as can be seen in Figure 1. As described in York and Hartley (1981), the female harvest itself provides an …

Solving The Habitat Dispersion Problem In Forest Planning, Stephen P. Mealey, James F. Lipscomb, K. Norman Johnson

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The National Forest Management Act (NFMA) of 1976 (16 U .S.c. 1600) requires that each National Forest, by 1985, prepare one integrated management plan that provides for multiple use and sustained yield for goods and services (36 CFR 219). Such plans must, by inference, emphasize single resources only to the extent that thresholds or minimum legal conditions for all other resources are always provided (Clawson 1975). The goal for wildlife to be met by each forest plan is: manage wildlife habitats to maintain viable populations of all existing native vertebrate species in the planning area (the forest) and maintain and …

Spotted Owl Research And Management In The Pacific Northwest, Eric D. Forsman, Kirk M. Horn, William A. Neitro

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

In recent years, a rapidly expanding body of research has made wildlife biologists and land managers increasingly aware that old-growth forests are critical wildlife habitat. This has come at a time when old-growth forests are rapidly being eliminated in order to meet human demands for wood products. In Oregon, for example, it is anticipated that virtually all remaining old-growth forests on commercial forest lands will be harvested by the year 2020 (Beuter et al. 1976). Thereafter, regenerating forests on cutover areas will be intensively managed and harvested every 60-80 years on most sites. If history is a good example, it …

Project Applications Of The Forest Service Rocky Mountain Region Wildlife And Fish Habitat Relationships System, Judy L. Sheppard, Dale L. Wills, James L. Simonson

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Wildlife and Fish Habitat Relationships (WFHR) is a Forest Service system for integrating wildlife and fish information and assessment data into interdisciplinary land and resource management. WFHR is a comprehensive organization of information in a format useful for managing wildlife through the management of their habitats. The WFHR System assists the Forest Service in meeting its goal of managing wildlife and fish habitats, both for species diversity as well as for individual species of management concern.
The Rocky Mountain WFHR System (USDA Forest Service 1981a) organizes information on 853 vertebrate animal species occurring on National Forest System lands in the …

Cooperative Project On The Weak Calf Syndrome, William G. Kvasnicka

Roman L. Hruska U.S. Meat Animal Research Center: Reports

The "Weak Calf Syndrome" has been gaining wide recognition throughout the north~est and Rocky Mountain regions. The specific syndrome was first noted as possibly being caused 'by a new entity by Dr. Jack Ward in the Bitterroot Valley of Montana after Dr. Ward was unable to relate the observations of necropsied specimens with that of any known published reports. The actual origin of the disease responsible for the specific syndrome noted in the area is not known and may have had its origin elsewhere. However, interest in the problem is increasing in view of the apparent recognition of the disease …

Testicular Development And Onset Of Puberty In Beef Bulls, Donald D. Lunstra

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Selection and management of young beef bulls have been hampered by a lack of information on reproductive development, growth, and puberty. The use of an increasing number of sire breeds in the beef cattle industry has placed additional emphasis on the importance of defining differences in sexual maturation within and among breeds. We conducted the following studies as part of a program designed to characterize reproductive development and puberty in breeds of beef bulls.

California's Central Valley Wintering Waterfowl: Concerns And Challenges, David S. Gilmer, Michael R. Miller, Richard D. Bauer, John R. Ledonne

United States Fish and Wildlife Service: Publications

Few places on the North American continent can boast of the concentrations of migratory birds that winter in the Central Valley of California. Long before agriculture and industrialization came west, this great valley served as a major wintering ground for millions of migratory birds. Fall flights of waterfowl, shorebirds, waders, raptors, and passerines returned annually to inhabit the vast wetland, riparian, and grassland habitats which covered the valley floor (Dasmann 1966, Bakker 1971).
Major changes in the Central Valley during the last century have profoundly influenced its physical and biological features. Wetland, riparian, and grassland habitats have been devastated by …

Current Status And Management Challenges For Tule White-Fronted Geese, Daniel E. Timm, Michael L. Wege, David S. Gilmer

United States Fish and Wildlife Service: Publications

Since large, dark tule white-fronted geese (Anser albifrons gam belli Hartlaub) were first described in Texas over a century ago by Hartlaub (1852), and again 65 years later in California by Swarth and Bryant (1917), tule geese have been the subject of at least 14 studies in California and 8 attempts to locate summering birds in the Artic. Central questions of these efforts have been: Is the tule goose a distinct subspecies? What is their range and population size? How can the birds be identified? and What threatens their existence?
The purpose of this paper is to present the …

Production Of Shigella Dysenteriae Type 1-Like Cytotoxin By Escherichia Coli, Alison D. O'Brien, Gerald D. Laveck, Michael R. Thompson, Samuel B. Formal

Uniformed Services University of the Health Sciences

Strains of Escherichia coli previously implicated or proven to be causes of diarrhea were examined for production of a toxin similar to that of Shigella dysenteriae type 1 (Shiga). Organisms grown in an iron-depleted broth were lysed by pressure disruption followed by ultracentrifugation. Saline-dialyzed extracts were tested for cytotoxic effects on HeLa cells that were neutralizable with antiserum to Shiga toxin. Among the 13 E. coli strains so analyzed, 11 made a Shiga-like cytotoxin in levels ranging from trace (two avirulent isolates) to amounts equivalent to S. dysenteriae type 1 (two noninvasive strains that did not make E. coli heat-labile …

Modes Of Being In Gabriel Miro's El Angel, El Molino, El Caracol Del Faro, Robert Johnson

Spanish Language and Literature Papers

El angel, el molino, el caracol del faro is (at least in the first four of its five parts) a kind of modern Calila e Dimna, a collection of fables, parables, fantasies and legends. It contains twenty estampas, five under the heading «Estampas rurales,» three «Estampas de cuentos,» three «Estampas del agua, del rio y del mar,» five «Estampas de un le6n y una leona,» and four «Estampas del faro,» all of which appeared individually in Barcelona's La Publicidad between February 7, 1919 and October 6, 1920. The collection seems to be an anomaly among the other secular works …

Breed Comparisons For Age And Weight At Puberty In Gilts, L. K. Hutchens, R. L. Hintz, R. K. Johnson

Department of Animal Science: Faculty Publications

Data on 213 purebred and 524 crossbred gilts produced in a four-breed diallel crossing design involving the Duroc (D), Yorkshire (Y), Landrace (L) and Spotted (S)breeds were analyzed for age and weight at puberty. The breed of sire x breed of dam interaction was significant for both age and weight at puberty. However, differences among reciprocals were not significant, and thus, reciprocal means were combined. Crossbreds were younger (7.9 d) and heavier (1.2 kg) at puberty than purebreds. Significant heterosis for age at puberty was found for D X L (-14.3 d),S x D (-12.8 d) and S x L …

The Cultural Landscape Of. The Pawnees, Richard White

Great Plains Quarterly (through 2013)

In June of 1871, at the Pawnee village on the Loup River, the chiefs and soldiers of the four tribes of the Pawnee Nation met in council with their Quaker agent and superintendent. The council convened in the midst of the spring ceremonies; the women had already planted the fields and the priests had performed the Young Mother Corn ritual that ended the planting cycle. As it had for centuries, the attention of the Pawnees shifted to the mixed-grass plains hundreds of miles to the west where, in the first of their semiannual hunts, they would soon seek simultaneously to …

The Pioneer Landscape: An American Dream, David Lowenthal

Great Plains Quarterly (through 2013)

To speak of pioneers, of the pioneer character, of the pioneer spirit, instantly brings vivid impressi~ns to mind. But what and where is the pioneer landscape? No more elusive or evanescent place exists. The pioneer landscape appears here, there, almost everywhere, for only a moment early in the chronicle of any locale; then it vanishes, never to return. Only once in its history is a place a pioneer country. Other pioneering efforts may follow-the extraction of some hitherto unknown or unusable resource, the creation of some new social orderbut these efforts do not occur in pioneer landscapes or circumstances. Lindbergh …

Plains Landscapes And Changing Visions, John Milton

Great Plains Quarterly (through 2013)

The plains landscape has always been a dominant factor in the lives of those people who confront it daily. Our recognition of pioneer nineteenth-century landscapes is a fusion in the mind of what we remember from early reports and visual images and our own personal vision of the land as it looks today. That concept of the pioneer landscape remains in our minds even as we respond to the contemporary landscape or through the imagination create our own. One reason, then, that pioneer landscapes are still important to us is that they have influenced our perceptions of the plains in …

The Dreaded Discussion: Ten Ways To Start, Peter Frederick

To Improve the Academy: A Journal of Educational Development

The conspiracy of silence is breaking up: we are learning to talk more openly about our joys and fears as teachers, our achievements and frustrations in the classroom. As I have listened to my colleagues talk about their students and their classrooms, the one fear and frustration mentioned more than any other, as for Henry Adams, was in leading a discussion. No matter how many articles on technique we read, or workshops we attend, the dreaded discussion continues to bother us more than any other part of our daily teaching lives. Freshman seminar and discussion-based core programs continue to develop. …
