Strategies For The Preservation Of Rare Animals, Clayton M. White Dec 1979

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 Dec 1979

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 Dec 1979

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.

Rare Aquatic Insects, Or How Valuable Are Bugs?, Richard W. Baumann Dec 1979

Rare Aquatic Insects, Or How Valuable Are Bugs?, Richard W. Baumann

Great Basin Naturalist Memoirs

Insects are an important element in the analysis of aquatic ecosystems, (1) because the limited dispersal abilities of many aquatic species means that they must make a living under existing conditions, and (2) because they are often sensitive to slight changes in water and stream quality, thus making excellent indicators of the physical and chemical conditions in a system. Examples of rare, ecologically sensitive species are presented from the Plecoptera, Ephemeroptera, and Trichoptera. Detailed studies of rare aquatic insect species should produce important information on critical habitats that will be useful in the protection of endangered and threatened species in …

Perspective, John L. Spinks Dec 1979

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 Dec 1979

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 Dec 1979

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 …

Endangered And Threatened Fishes Of The West, James E. Deacon Dec 1979

Endangered And Threatened Fishes Of The West, James E. Deacon

Great Basin Naturalist Memoirs

The endangered and threatened fish fauna of the United States exhibits problems resulting primarily from habitat modification by man. The evolutionary history of the fauna has left it especially sensitive to biotic interactions. In addition, many forms are of such restricted distribution that the entire taxon can be destroyed by very minor perturbations. The effects of habitat modification on woundfin and roundtail chub in the Virgin River of Utah, Arizona, and Nevada are discussed. Parasitism by Lernea on White River springfish is shown to coincide with population decline in some, but not all, cases. Population declines of Pahrump killifish are …

Endangered Species: Costs And Benefits, Edwin P. Pister Dec 1979

Endangered Species: Costs And Benefits, Edwin P. Pister

Great Basin Naturalist Memoirs

Biologists are often placed in the difficult position of defending a threatened habitat or animal with vague reasoning and faulty logic, simply because they have no better rationale at their immediate disposal. This places them at a distinct disadvantage and literally at the mercy of resource exploiters and their easily assignable dollar values. Although the initial dollar cost of delaying precluding "developing" may be significant, the long-term benefits of saving the biological entities which might otherwise be destroyed are likewise great and are measurable in concrete terms which society is only now beginning to appreciate. Case histories are presented, a …

Endangered Species On Federal Lands. Panel: Part Iii, The Bureau Of Land Management's Endangered Species Program, Richard Vernimen

Great Basin Naturalist Memoirs

It is the responsibility of the Bureau of Land Management (BLM) to conserve plants and animals . . . and the habitat on which they depend . . . which are officially listed according to federal or state laws in categories that imply significant potential for extinction. The BLM also provides for the conservation of the habitats of unlisted extinction-prone (i.e., sensitive) plants and animals. It also applies to all BLM programs and actions related to the public lands, the federal subsurface mineral estate, and the submerged lands of the Outer Continental Shelf (OSC).

Análisis Fonológico De Las Líquidas En Un Dialecto Rural Dominicano, Orlando Alba Oct 1979

Análisis Fonológico De Las Líquidas En Un Dialecto Rural Dominicano, Orlando Alba

Faculty Publications

En este trabajo se realiza un análisis de la variación de las líquidas /r, l/ en un dialecto rural dominicano con el enfoque de la fonología generativa. Se toman como base los datos aportados por las obras dialectales publicadas hasta la fecha. Se busca mostrar que la concepción generativa permite realizar una descripción coherente de los procesos de cambio fonético, especialmente el de la vocalización de /r, l/ implosivas en la zona dominicana del Cibao.
