Impact Of Spacing Behavior And Predation On Population Growth In Meadow Voles, Dale M. Madison

Eastern Pine and Meadow Vole Symposia

Free-ranging, sexually mature meadow voles (Microtus pennsylvanicus) were tracked using radiotelemetry from June through August 1974, 1975 and 1978. Up to 20 voles were monitored concurrently to derive estimates of intraspecific spacing and natural predation in an effort to clarify processes involved in the limitation of population growth. The daily ranges of the males, as compared to those of the females, were larger, more variable in size, and changed location more from one day to the next. Adult females usually maintained territories free of other females; males overlapped considerably among themselves. Males temporarily moved into the areas occupied by estrous …

The Endrin Rpar, Lawrence S. Ebner

Eastern Pine and Meadow Vole Symposia

In July, 1976 the U.S. Environmental Protection Agency issued a "Notice of Rebuttable Presumption Against Registration and Continued Registration of Pesticide Products Containing Endrin" (41 Fed. Reg. 31,316). The purpose of this Notice was to initiate an "RPAR" review to determine whether continued usage of endrin, including the use of endrin for vole control, poses a "substantial question of safety" necessitating cancellation proceedings under Section 6(b) of the Federal Insecticide, Fungicide and Rodenticide Act ("FIFRA").

Lake Mead And Lake Powell Salinity Reports, Cathy Lee, Steve Gazafy

Publications (WR)

The enclosed reports were compiled for the Colorado River Water Quality Office based on salinity data for Lake Mead and Lake Powell. According to the regional director of the office, the reports are not considered "polished" documents for public distribution. However, he considers them to be "interesting, rough appraisals of general trends that may be very important In our understanding the hydro-salinity system in the Colorado River."

Planting Trees-Why Rather Than How, Angelo Cohn

Journal of the Minnesota Academy of Science

Three evergreen plantings over 25 years in a private woodland are described and evaluated in terms of reforestation, economics and personal satisfaction. Credit is given to government foresters and support from the Minnesota Department of Natural Resources (DN\R) and the federal Forest Incentives Program (FIP). Changes in site preparation methods, selection of species and planting procedures are discussed as outcomes of research and field experience. Cost-benefits are assigned principally to human values reflected in family learning and enhanced appreciation of the ecosystem of rural Minnesota.

Management Of Antarctic Krill, Paul Setliff

Marine Affairs Theses and Major Papers

This study pertains to the problem of international activity in an area of political and ecological sensitivity, the Southern Ocean. Of specific concern is the question of which group of states should have a voice in management of Antarctic krill. The niche filled by krill within the ecosystem and its potential as a fishery is discussed. Past international practice has been affected for the most part by the Antarctic Treaty of 1959 which has maintained a somewhat exclusive "club" of nations as the overseers of Antarctic activity. However, states not party to the 1959 Treaty are becoming interested in the …

State Government And Ocs Policy: An Analysis Of The Outer Continental Shelf Lands Act And The Amendments Of 1978, Bruce Vild

Marine Affairs Theses and Major Papers

An Energy Research and Development Administration report indicates that the United States is increasing its dependence on oil from the countries that participated in the 1973 oil embargo. Given the volatile situation in the Middle East at this writing, the Carter Administration's peace initiatives notwithstanding, this seems an imprudent policy. And, at a time when "Project Independence" is a recent memory, there is a great deal of irony in increased importation. It seems in the Nation's best interest to reverse that trend. Natural gas is also in demand, of course, especially in the Northeast during the winter. The best solution …

A Preliminary Cost-Benefit Analysis Of The Proposed St. Thomas-St. John Sand Mining Project, Random Dubois

Marine Affairs Theses and Major Papers

A territorial ban on beach and sand removal in the U. S. Virgin Islands has resulted in a search for alternative sources. Insecure extra-territorial reserves and high shipping costs have made sand importation prohibitive. Recent surveys conducted in 1977 by the U. S. Geological Survey identified several nearshore sources of aggregate adjacent to the island of St. Thomas. In a 1978 workshop jointly conducted by the Government of the Virgin Islands and the National Oceanic and Atmospheric Administration various alternatives were presented for sand extraction. Two alternatives are examined using a cost benefit approach.

Blm Utah Final Initial Wilderness Inventory, United States Bureau Of Land Management

All U.S. Government Documents (Utah Regional Depository)

In the BLM Wilderness Program, only inventory is completed without consideration of other uses of the land. The wilderness inventory is only for the purpose of determining the presence of wilderness characteristics. It is on that basis that wilderness study areas will be identified. The comparison of wilderness values with other resource values is not part of the wilderness inventory process. It is a valid and necessary part of phase two study. When we enter phase two, the latter part of 1980, it will be imperative for us to consider and resolve whether the orderly development or wise preservation within …

Fisheries Report No 38 - The Shark Bay Prawn Fishery (1970 - 1976), J. W. Penn, R. W. Stalker

Fisheries Research Reports

The existence of prawn stocks in Shark Bay, Western Australia, has been known since 1904 when the sailing ketch "Rip" on charter to the Western Australian Government, trawled large quantities of prawns from the area between Bernier Island and the mainland, Gale (1905). Although the Fisheries research vessel "Lancelin" trawled potentially commercial quantities of prawns from Shark Bay in the early 1950's, it was not until 1962 that a regular fishery was begun.

Today the prawn stocks of Shark Bay support Western Australia's largest and most consistent prawn fishery, having an annual production currently exceeding 2 000 tonnes. The catch …
