Challenges For The New West: Economic Impacts Of Wilderness In Nevada's Rural Counties, Lesley Regina Argo Dec 2001

Challenges For The New West: Economic Impacts Of Wilderness In Nevada's Rural Counties, Lesley Regina Argo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Public lands designated as part of the National Wilderness Preservation System are removed from multiple-use management for protection of their natural condition. Opponents argue that "locking up" the natural resources on these lands through designation will undermine the rural economies in the west that are dependent upon extractive industries such as mining and logging. Proponents argue that the "Old West" reliance on extractive industries is declining and, in the "New West", wilderness promotes economic development in rural communities by preserving the amenity values that draw population and employment to the region. Characteristics of Nevada's economy, population and land challenge the …


Intermediate Rings Between A Local Domain And Its Completion, Ii, William Heinzer, Christel Rotthaus, Sylvia Wiegand Oct 2001

Intermediate Rings Between A Local Domain And Its Completion, Ii, William Heinzer, Christel Rotthaus, Sylvia Wiegand

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We present results connecting flatness of extension rings to the Noetherian property for certain intermediate rings between an excellent normal local domain and its completion. We consider conditions for these rings to have Cohen-Macaulay formal fibers. We also present several examples illustrating these results.


Evaluation Of Comparative Watercraft Personal Property Taxation In Middle Peninsula Localities, Thomas J. Murray Sep 2001

Evaluation Of Comparative Watercraft Personal Property Taxation In Middle Peninsula Localities, Thomas J. Murray

Reports

The Marine Business and Coastal Development Program, Sea Grant Marine Advisory Services at the Virginia Institute of Marine Science, (VIMS) has completed a characterization of the personal property taxing methodologies currently used by Middle Peninsula localities. In conjunction with the Middle Peninsula Planning District Commission's (MPPDC) Coastal Technical Assistance Program, the investigation details the following information:

1. Documentation of the watercraft taxing methodology currently used in the MPPDC counties of Gloucester, Mathews, Middlesex, King and Queen, King William, and Essex County.

2. A comparison of resulting taxes assessed by each of the MPPDC localities on some "standardized" boats.

3. A …


Virginia Boating Plan And Access Needs Assessment, Thomas J. Murray Sep 2001

Virginia Boating Plan And Access Needs Assessment, Thomas J. Murray

Reports

In an effort to support Virginia's application for federal grant funds under the Department of Interior's "Boating Infrastructure Grant Program" (Grants), the Marina Technical Advisory Program (MT AP) at the Virginia Institute of Marine Science has undertaken assessment of the state's recreational boating infrastructure needs. 1 A total of $32 million has been authorized over four years to fund this new program. It is designed to help states develop and maintain facilities for transient non-trailerable (26' and over) recreational boats. The Virginia Department of Health (VDOH) has provided overall leadership in the Boating Infrastructure Grants process and has been supported …


Fish Protection Measures To Ensure Fish For The Future, Jo Bunting Jun 2001

Fish Protection Measures To Ensure Fish For The Future, Jo Bunting

Fisheries management papers

The protection of Western Australia's aquatic animals, plants and habitats is important for many reasons. Fish, and many aquatic invertebrates, have significant commercial, recreational and social importance. Aquatic habitats provide food, refuge and breeding areas for fish and other animals. In addition, some habitats, such as rocky reefs and seagrass meadows, act as nursery sites for juvenile animals. Some habitats and their inhabitants (such as coral reefs) also have aesthetic values which support economically and socially important industries, such as tourism.


Ecological Implications Of Rockweed, Ascophyllum Nodosum (L.) Le Jolis, Harvesting, Jill C. Fegley May 2001

Ecological Implications Of Rockweed, Ascophyllum Nodosum (L.) Le Jolis, Harvesting, Jill C. Fegley

Electronic Theses and Dissertations

Harvesting of natural resources usually entails substantial removal of the target species. Where such species are dominant members of natural communities, their removal can have important consequences for their own regeneration as well as for the species assemblages associated with them. Rockweed is an ecologically and commercially important intertidal alga in the North Atlantic, and is increasingly being harvested in Maine. The effects of harvesting on regrowth are well known but little is known about its effects on the species that use this alga as habitat. This research focused on the ecological implications of A. nodosum harvesting on the associated …


Yellow Jackets (Vespula Spp.) Disperse Trillium (Spp.) Seeds In Eastern North America, Jennifer A. Zettler, Timonthy P. Spira, Craig R. Allen Jan 2001

Yellow Jackets (Vespula Spp.) Disperse Trillium (Spp.) Seeds In Eastern North America, Jennifer A. Zettler, Timonthy P. Spira, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Approximately 70 plant families worldwide have ant-dispersed seeds (myrmecochory). In this putative ant-plant mutualism, ants are attracted to and disperse seeds that have a lipid-rich elaiosome. We observed yellow jackets (Vespula spp.) dispersing seeds of three elaiosome-bearing species-Trillium cuneatum, T. undulatum and T catesbaei-in the Blue Ridge Mountains of North Carolina and South Carolina. Moreover, we estimated the mean distance yellow jackets dispersed seeds of T. cuneatum by placing intact fruits on index cards and recovering dispersed seeds on sheets placed on the ground surface. Of the seeds presented, 41% were recovered and the average dispersal distance …
