The Taxonomic Status Of The Rosy Boa Lichanura Roseofusca (Serpentes: Boidae), John R. Ottley, Robert W. Murphy, Geoffrey V. Smith
Great Basin Naturalist
Evidence is presented indicating that Lichanura roseofusca and Lichanura trivirgata are conspecific. Data include the report of an intermediate specimen from El Arco, Baja California Norte, a site midway between the previously known peninsular ranges of the two species; captive hybridization provides additional support for the conclusion.

Current State Of Affairs Of Japanese Language Information Processing And Its Practice At The University Of Tsukuba, Kazuhiko Nakayama, Akifumi Oikawa
Current State Of Affairs Of Japanese Language Information Processing And Its Practice At The University Of Tsukuba, Kazuhiko Nakayama, Akifumi Oikawa
Journal of East Asian Libraries
I. Introduction. The University of Tsukuba opened its doors in October 1973 as a university of tomorrow with (1) the introduction of a new framework for education and research, (2) a novel university management, and (3) an open university as its three distinguishing features. During the preparatory stages for founding the university, plans were made to establish a computer center and introduce a large-scale computer. At this early stage, research and development could be carried out to develop centralized operations control and efficient uses of the computer, as well as applications of the computer to education, research, and university administration. …

Papers In Language And Literature Delivered At The 1979 Meeting Of The Association, John Boni
Papers In Language And Literature Delivered At The 1979 Meeting Of The Association, John Boni
Quidditas
The papers in language and literature covered, as might be expected, a broad range of interests: from Beowulf to Paradise Lost, from paleography to cultural change. The following is an attempt too summarize the content of each paper, staying as close as possible to the author's pattern of argument, and following the author's own words, directly or by paraphrase; the order here follows that of the program. Where only an abstract was available as a source of summary, this has been noted.

Water Use In Agriculture Now And For The Future, B. Gardner Delworth
Water Use In Agriculture Now And For The Future, B. Gardner Delworth
Faculty Publications
Water is the primary limiting factor in agriculture in the United States and the world. The western states have gained importance in agricultural production only through extensive use of irrigation from surface and groundwater sources. With the increase in population, these water supplies are facing new pressures for reallocation. Accurate scientific information concerning water availability, behavior, management, and value is essential in optimizing water allocation on farms, in agriculture, and among agriculture and the various other uses. This report is an overview of the physical, institutional, economic, and sociological aspects of the water issue from the standpoint of agriculture. It …
Sex, Sickness And Statehood: The Influence Of Victorian Medical Opinion On Self-Government In Utah, E. Victoria Grover-Swank
Sex, Sickness And Statehood: The Influence Of Victorian Medical Opinion On Self-Government In Utah, E. Victoria Grover-Swank
Theses and Dissertations
In the struggle for self-government which occupied the Mormon population of Utah between their entry into the Great Basin in 1847 and statehood in 1896, the issue of polygamy dominated public discussion. The non-Mormon population of the United States generally objected to the practice of polygamy, in large part because of Victorian attitudes towards sexual activity and the presumed physical and mental results of violating Victorian sexual norms. It was assumed by most Americans that polygamy, by violating those norms, caused real physical damage to the Latter-day Saints in Utah; damage that disqualified them from holding full and equal political …
Historic Preservation In Utah: 1960-1980, John W. Haggerty
Historic Preservation In Utah: 1960-1980, John W. Haggerty
Theses and Dissertations
Historic preservation in Utah from 1960 to 1980 has reflected major national trends and trends peculiar to Utah. The most important event which increased the influence of the federal government in preservation activities in Utah was the passage of the Federal Historic Preservation Act of 1966. This law influenced the Utah State Historical Society to become active in preservation in Utah. The battles to save the L. D. S. tabernacles in the 1960s and 1970s led to the formation of the Utah Heritage Foundation. This organization has been responsible for the heightened awareness of historic preservation in Utah. During the …

Culture And Species Endangerment, Roland C. Clement
Culture And Species Endangerment, Roland C. Clement
Great Basin Naturalist Memoirs
Species endangerment has so far been addressed mostly by biologists. It is now important to involve social scientists, inasmuch as the problems are man caused. The history of our attitudes, our uses of the land, and the reasons wherefore are problems for everyone.
The evidence suggests that the causes of endangerment may be grouped under (1) direct and indirect exploitation of resources, and (2) population displacement by modern agriculture, with consequent migration to the city or to the forest frontier, where accelerated forest destruction is the result. The displaced people are part of the marginalized two-thirds of the human race …
The Meaning Of "Rare" And "Endangered" In The Evolution Of Western Shrubs, Howard C. Stutz
The Meaning Of "Rare" And "Endangered" In The Evolution Of Western Shrubs, Howard C. Stutz
Great Basin Naturalist Memoirs
In the evolutionary process, species continually come and go. Consequently, all species on earth today were, at one time, "rare and endangered" while in their infancy, and most will become "rare and endangered" once more as they are replaced. Therefore, decisions relative to protecting rare and endangered species are largely meaningless if based on numbers alone. They must include information about their biology and evolutionary history. Lists of endangered forms currently being prepared apparently include only those which are (1) scarce (rare and of restricted distribution), (2) named, and (3) sponsored. Their biological, economic, and academic values may be more …
Strategies For The Preservation Of Rare Plants, Arthur H. Holmgren
Strategies For The Preservation Of Rare Plants, Arthur H. Holmgren
Great Basin Naturalist Memoirs
Preservation of the habitat is the only logical strategy to save endangered species from early extinction. Ecological amplitudes of rare species are very narrow, so transplantation to such alien sites as botanical gardens is not a solution. Protection may not be the answer. We must learn as much as we can about the biology of the species in question, in the field and under laboratory conditions. The first steps must be to determine the distribution. This would be followed by analysis of soils by means of physical and chemical studies. Pollination ecology, associated species, phenological records, and genetic and cytological …
The Epoch Of Biotic Impoverishment, Thomas E. Lovejoy
The Epoch Of Biotic Impoverishment, Thomas E. Lovejoy
Great Basin Naturalist Memoirs
1978 was the first year in the history of man that legal power to eradicate a species was established. It is one of a number of signs of rapidly accelerating rates of extinction which may result in reduction of biological diversity by one-seventh to one-fifth, with a parallel reduction in the planet's capacity to support man and a permanent reduction in the potential body of biological knowledge. Species loss of such a degree would warrant designating the close of the Recent epoch and the opening of a new one of Biotic Impoverishment. A great deal of the extinctions will occur …
Endangered And Threatened Plants Of Utah: A Case Study, Stanley L. Welsh
Endangered And Threatened Plants Of Utah: A Case Study, Stanley L. Welsh
Great Basin Naturalist Memoirs
Endangered and threatened plants of Utah are evaluated as to their distribution in phytogeographic subdivisions, substrates, plant communities, elevations, and geological strata. The phytogeographic subunits were partitioned and comparisons made of distribution as outlined for the parameters cited above. A predictive model is suggested based on the nonrandom distribution of endemic plant species.
Management Programs For Plants On Federal Lands, Duane Atwood
Management Programs For Plants On Federal Lands, Duane Atwood
Great Basin Naturalist Memoirs
The plant phase of the Endangered Species Program is discussed from the point of view of a professional botanist in government service. Some of the new amendments are also discussed from a botanical standpoint. Federal agency programs and policies in the western United States are briefly reviewed. The strength of the Endangered Species Program is dependent upon input from qualified professional biologists in and out of government service. Some of the problems encountered in the program are outlined.
Strategies For The Preservation Of Rare Animals, Clayton M. White
Strategies For The Preservation Of Rare Animals, Clayton M. White
Great Basin Naturalist Memoirs
Strategies used to enhance or help restore rare and endangered animal species are reviewed. No new strategies are presented, but rather a review of various levels at which programs can be initiated are indicated. Nearly 93 percent of the recognized endangered animals are vertebrates. Programs to help restore vertebrates can be aimed at either the habitat or the organism level. Habitat restoration or preservation is the more difficult to achieve and, accordingly, most strategies are aimed at the organism. Species, populations, or communities are ecosystems can be treated, but most often each requires a separate approach. Among organisms the species …

The Importance Of Bees And Other Insect Pollinators In Maintaining Floral Species Composition, V. J. Tepedino
The Importance Of Bees And Other Insect Pollinators In Maintaining Floral Species Composition, V. J. Tepedino
Great Basin Naturalist Memoirs
Bees and other insect pollinators which are necessary for the successful reproduction of most species of flowering plants, including agricultural crops, have been ignored by our preservation efforts. This is unfortunate because bees, as low-fecundity organisms, are very susceptible to insecticides and populations are slow to recover from perturbations. Many species of bees, particularly specialized species in the western United States and the tropics, are vulnerable to extinction. With extinctions of specialized forms, generalized species, especially fugitives, are expected to increase because of their ability to utilize a variety of resources and survive beyond the confines of preserves. The possible …
Endangered Animals In Utah And Adjacent Areas, Douglas Day
Endangered Animals In Utah And Adjacent Areas, Douglas Day
Great Basin Naturalist Memoirs
This paper presents a brief background on Utah's experience with the Endangered Species Act of 1973 to date, the Division on Wildlife Resources' involvement with resident endangered wildlife forms, including the Utah prairie dog, peregrine falcon, bald eagle, woundfin, Colorado squawfish and humpback chub, and problems associated with the listing of native fauna. Also discussed is a proposal to vest the division with authority for endangered plants by legislative mandate.
Perspective, John L. Spinks
Perspective, John L. Spinks
Great Basin Naturalist Memoirs
The fact that mankind has desecrated much of the natural world is recognized. The rate of plant and animal extinction has increased in North America from an estimated 3 species per century 3,000 years ago to an average of 143 per century since 1620. Endangered species protection began in the Fish and Wildlife Service in 1938 with the purpose of the Aransas National Wildlife Refuge for the whooping crane. A committee on rare and endangered species was formed in 1962 by the director of the Fish and Wildlife Service and a tentative list was published in 1964. The Endangered Species …
The Law And Its Economic Impact, Donald A. Spencer
The Law And Its Economic Impact, Donald A. Spencer
Great Basin Naturalist Memoirs
There is no adequate inventory of population size and distribution of most of the world's animal and plant species and lower taxa. Furthermore, populations are rarely static and continue to change in response to both natural and man-made factors. Thus clearance today for public works or industrial projects can be reversed tomorrow as new information becomes available. Lacking assurance that a project can be completed without new endangered species surfacing places an untenable constraint on the commitment of dollars for new long-term programs.
As a consequence of the absence of data, studies to determine occupied range, population levels, and habitat …

Strategies For Preservation Of Rare Plants And Animals, G. Ledyard Stebbins
Strategies For Preservation Of Rare Plants And Animals, G. Ledyard Stebbins
Great Basin Naturalist Memoirs
Human preservation of endangered species apparently commenced prior to recorded history with Ginks biloba, in China, a tree now known only under cultivation. A number of species have become extinct because man either failed to recognize their value or did not act quickly enough to preserve them even when their value was appreciated. A philosophy of conservation must be based upon cooperation with others looking to the future. Appropriate strategies that could be adapted from the military to achieve the objectives of species conservation include: (1) Know your enemy, his strengths and weaknesses, and the tactics he is likely …
