The Impact On The Navy Of Public Concern With Control Of Pollution Of The Seas By Oil, Robert Augustus Fisher
The Impact On The Navy Of Public Concern With Control Of Pollution Of The Seas By Oil, Robert Augustus Fisher
Marine Affairs Theses and Major Papers
It is difficult at best to evaluate the biological and chemical damages of oil pollution, but the physical effects are graphically evident in the blackened beaches and coastlines around the world and in the floating "tar-balls" found in mid-ocean. It is this dramatically visible effect that has stirred public concern. Thus, prevention of such damage is high on the list of priorities for both national and international concern. In the face of the ever increasing potential for pollution, President Nixon has pledged that federal agencies will take the lead in pollution abatement programs.

Males of P. blainvillei are still sexually immature at a length of 128.5 centimeters, females become sexually active at a length of 137 centimeters. Off Uruguay, pregnant females have fetuses 6 centimeters in length …
Telemetered Heart Rates Of Free-Living Uinta Ground Squirrels In Response To Social Interactions, Robert L. Ruff
Telemetered Heart Rates Of Free-Living Uinta Ground Squirrels In Response To Social Interactions, Robert L. Ruff
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Free-living Uinta ground squirrels (Spermophilus armatus) were instrumented with miniaturized ECG radio-transmitters to measure their short-term and long-term heart rate responses to social interactions. A continuous trapping and direct observation program prior to and during the study provided complete behavioral and life history information for virtually all ground squirrels on the 22-acre study area.
Three broad categories of heart rate information were obtained: responses by squirrels (1) in their burrows, (2) above ground during social interactions, and (3) above ground when animals were not fighting and when conspecifics were both absent and present.
Marked changes in the heart …

Spawning And Early Life History Of Largemouth Bass (Micropterus Salmoides) In Wahweap Bay, Lake Powell, Kent D. Miller
Spawning And Early Life History Of Largemouth Bass (Micropterus Salmoides) In Wahweap Bay, Lake Powell, Kent D. Miller
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Spawning time and habitat of largemouth bass, survival of embryos, and growth and food habits of fingerlings were studied in 1968 and 1969 at Wahweap Bay, Lake Powell. Spawning began in mid- to late-April, when mean daily water temperature at nesting depths was 14.4-15.0 Centigrade (58-59 Fahreheit), and continued until mid-June. Most spawning took place on the northeast shore of the bay. Sandstone rubble was the most commonly used bottom type for nesting, either at the base of ledges or around large sandstone boulders. Mean nest depth increased from 1.63 meter to 4.54 meters (5.36 feet to 14.90 feet) in …
The Role Of Compulsory Sealanes In Resolving Multiple-Use Conflict On The Continental Shelf, Alfred P. Manning
The Role Of Compulsory Sealanes In Resolving Multiple-Use Conflict On The Continental Shelf, Alfred P. Manning
Marine Affairs Theses and Major Papers
An analysis of the nature of multiple-use conflict on the continental shelf developed with particular emphasis on the involvement of ocean transportation and offshore oil recovery. The wide-ranging effects which offshore marine accidents may have on coastal residents is discussed. Trends indicate a growth in the level of conflict stemming from competition between those wishing to use the same ocean space for the same purpose, the same ocean space for different purposes, and different but related ocean space for incompatible purposes. Ocean transportation is identified as the single common element in all three conflict categories. Restriction on traditional concepts of …
Oceanic Disposal Of Radioactive Wastes: Effects And Proposals, Billy M. Ervin
Oceanic Disposal Of Radioactive Wastes: Effects And Proposals, Billy M. Ervin
Marine Affairs Theses and Major Papers
An investigation of the effects of radioactive waste disposal into the oceans pursued by an examination of the hazards involved, the present sources of radioactive wastes and future prospects. The longevity of many radioactive elements, coupled with the awesome consequences to which even a slight miscalculation may lead, are convincing arguments for the most conservative approach to the problem of disposal of radioactive wastes. Present day disposal of radioactive wastes in the oceans, while significant, have not yet had major discernible effects on man or marine life. However, with the worldwide explosion of electrical power demand and the increasing use …
Management Of Natural Lakes In The Northern Great Plains, D. B. Mccarraher
Management Of Natural Lakes In The Northern Great Plains, D. B. Mccarraher
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
Approximately 2,800 natural lakes smaller than 10 acres in size are found in the northern plains region of Nebraska, South Dakota and North Dakota. Water quality characteristics vary greatly among lakes in close geographical proximity. They range from fresh to highly mineralized bicarbonate-carbonate-hydroxide (alkaline) to chloro-sulfate (saline) types and regionally represent the largest concentration of inland mineral waters in North America. Water quality together with shallow basin morphometry exert major environmental influences on the fisheries in great plains natural lakes.
In the sandhills region of Nebraska (20,000 sq. mi.) only about 45% of the estimated 1,400 natural lakes support fish …

Effects Of Season And Intensity Of Use On Desert Vegetation, C. Wayne Cook
Effects Of Season And Intensity Of Use On Desert Vegetation, C. Wayne Cook
UAES Bulletins
Desert ranges of the Great Basin area support about 9 million cattle and sheep for 5 to 6 months each winter. Many of these same ranges are used by cattle year-long.
If forage is not available on desert ranges, livestock have to be wintered on farmsteads or in feedlots after they are forced from the mountains and foothills by snow. Since feeding during the winter is expensive and reduces the economic efficiency of the range livestock operation, there is real advantage in properly managing the desert ranges and conserving the supply of forage for winter grazing.
Managing desert ranges for …

Grain Sorghum In The Ord Valley : Three Crops A Year?, P J. May
Grain Sorghum In The Ord Valley : Three Crops A Year?, P J. May
Journal of the Department of Agriculture, Western Australia, Series 4
High temperatures and ample irrigation water allow grain sorghum to be grown throughout the year on the Ord River Irrigation Area, and observations in 1969-70 indicated that it may be possible in this area to produce three crops in one year from one planting, by ratoon cropping.
This article describes the technique and discusses its possibilities on the Ord.
The sorghum midge, one of the worst pests of sorghum, could well make ratoon cropping impossible, but the midge has not yet been seen in this area.
