Fisheries Report No 13 - Results Of A Biological Survey Of The Shire Of Kent, Western Australia, N. L. Mckenzie
Fisheries Research Reports
The Department of Fisheries and Fauna is responsible for the conservation of the native fauna in Western Australia. The main approach to this problem has been the creation of reserves for "The Conservation of Flora and Fauna". These reserves, known as "Wildlife Sanctuaries", are controlled by the Western Australian Wild Life Authority - a Statutory Authority serviced by the Department.
The object of the acquisition programme is to develop a reserve system which will include, as far as possible, a full and permanent cross-section of the State's native floral and faunal assemblages and, at the same time, provide for the …

Morphological And Ecological Relationships Of Etheostoma Caeruleum And Etheostoma Spectabile In West Central Indiana, Dennis E. Clark
All-Inclusive List of Electronic Theses and Dissertations
Etheostoma caeruleum Storer and Jii. spectabile (Agassiz) are closely related members of the family Percidae, subfamily Percinae, tribe Etheostomatinae. This group, consisting mostly of small, brilliantly colored darters, has been partially characterized by Collett ( 1963). Several papers have been published dealing with the biology of these two species. One or both species have been described by Storer (1845), Agassiz (1854), Reeves (1907, but see Trautman, 1930), Trautman (1930, 1957) Knapp (unpublished Ph.D. dissertation), Distler (1968), and others. Trautman (1930, 1957) Gerking (1945), and Hubbs and Lagler (1947) reported that h caeruleum lives in larger and faster streams, whereas JL_ …

A Eutrophication Model Of The White River Basin Above Beaver Reservoir In Northwest Arkansas, Robert A. Gearhart, Dee Mitchell, Louis Thibodeaux, Richard Meyers
A Eutrophication Model Of The White River Basin Above Beaver Reservoir In Northwest Arkansas, Robert A. Gearhart, Dee Mitchell, Louis Thibodeaux, Richard Meyers
Arkansas Water Resources Center Technical Reports
With national interest focused on man’s ever increasing degradation of the waters in this nation, it is clearly evident that an accurate assessment of all parameters influencing water quality needs to be made. Moreover, nutrient levels and budgets reflecting eutrophication trends are important parameters in the overall factors effecting water quality in lakes and reservoirs. The ability to predict future eutrophication levels will greatly enhance the retardation of the eutrophication process. Through mathematical simulation of this process, eutrophication can be analyzed and intelligent decisions regarding water quality management can be made.
Mathematical Modeling Of Stream Storage Potential, Hugh M. Jeffus
Mathematical Modeling Of Stream Storage Potential, Hugh M. Jeffus
Arkansas Water Resources Center Technical Reports
Streamflow data from unregulated streams in Arkansas were processed through Moran’s Model for a dam. The process involved calculating a cumulative gamma distribution for each stream as the streamflow values were incremented in units of 0.1 cubic feet per second per square mile of drainage area. This gamma distribution was then used as input for Moran’s Model. The output from Moran's Model includes the probability of the reservoir having zero contents as the size of the reservoir is decreased. The logarithm of the probability of zero contents, 1n PO, versus reservoir size, K, is a straight line of the form …

A Study To Improve Dissolved Oxygen Analysis Techniques To Facilitate Water Quality Field Survey Applications, R. W. Raible, M. K. Testerman
Arkansas Water Resources Center Technical Reports
This report describes studies made of the temperature characteristics of dissolved oxygen electrodes having a large surface area. Large area electrodes proved to have much longer lifetime between rejuvenations. Many measurements of dissolved oxygen in water need to be made in field situations where recalibration techniques would be difficult and where making temperature corrections is time consuming for operators who may be making numerous measurements. This study was directed toward design of a compensation circuit for a dissolved oxygen electrode which will give the best possible measurement over a large water temperature range of 5° - 35°C without the necessity …
Seasonal Movements And Habitat Selection Of Pheasant Cocks In South Dakota, Robert A. Fedeler
Seasonal Movements And Habitat Selection Of Pheasant Cocks In South Dakota, Robert A. Fedeler
Electronic Theses and Dissertations
Data were gathered on seasonal movements and habitat selection of 30 pheasant (Phasianus colchicus) cocks that were radio-equipped in eastern South Dakota from 1970 to 1972. Pheasant cocks stayed in an area of less than 100 acres from spring through hunting season. In winter, cocks used even smaller areas more intensively. Cocks moved about their home range by shifting their activity center rather than by adjustment in range of daily travel. Adult cocks seemed to have strong site attachments on a year-round basis. Immature cocks were more mobile, especially during the fall prior to hunting season. In spring, adult cocks …
Evaluation Of Cattle Use Of A Deer Winter Range In The Black Hills, David C. Hamm
Evaluation Of Cattle Use Of A Deer Winter Range In The Black Hills, David C. Hamm
Electronic Theses and Dissertations
Cattle use of a deer winter range in the Black Hills was investigated during the summer grazing seasons of 1971-1972. A U.S. Forest Service grazing allotment situated between Mystic and Redfern, South Dakota, was used as the study area. The allotment was divided into five grazing units or pastures managed collectively under a “rest-rotation” system of grazing. Three study sites were selected in each unit of the allotment, and 75 exclosures were erected on each site; a paired-plot method was used to collect data. Indices to use of sites by deer and cattle were obtained by counts of deer pellet …

Electronic Theses and Dissertations
A study of giant Canada goose (Branta Canadensis maxima) restoration in western South Dakota was conducted during 1970 and 1971. Nesting, production and mortality, homing, and pioneering were evaluated both years. Nesting began April 4 in 1970 and extended for 73 days, but the peak of nesting occurred from April 29 to May 5. In 1971, nesting began April 1 and continued for 69 days, with the peak occurring April 8-14. The peak of hatching occurred June 6-12 in 1970 and May 8-14 during 1971. Small stockponds were utilized for nesting both years. Islands were preferred nesting sites. Peninsulas and …
Chemical Survey Of Selected South Dakota Lake Sediments, Alan Ross Swanson
Chemical Survey Of Selected South Dakota Lake Sediments, Alan Ross Swanson
Electronic Theses and Dissertations
Available phosphorus, organic carbon, and organic nitrogen were measured in bottom sediments of 16 lakes and ponds in northeast South Dakota. These lakes were glaciated, relatively shallow, and productive. Ranges of the surface sediments were: available phosphorus, 2 to 42 ppm; organic carbon, 0.94 to 5.34 percent; and organic nitrogen, 0.29 to 0.79 percent. Ranges of subsurface sediments were: available phosphorus, 2 to 39 ppm; organic carbon, 0.54 to 6.06 percent; organic nitrogen, 0.19 to 0.88 percent. Concentrations in most lakes varied little from top to bottom. Hard-bottomed lakes generally decreased in nutrient concentrations from sediment surface of subsurface. Lower …

Origin And Transport Of Nutrients In The Upper Big Sioux River, South Dakota, Charles William Thompson
Electronic Theses and Dissertations
The upper Big Sioux River Basin, in northeastern South Dakota, was studied to determine the origin and transport of nutrients in the Big Sioux River. The area was divided into three segments. Two of the segments, the Big Sioux River and Willow Creek Basins, were primarily agricultural drainage areas, and one segment was the city of Watertown. Sampling stations were selected to facilitate the determination of nutrient inputs to the river from each of these segments and to determine the nutrient load in the river leaving the study area. Nutrients studied included total orthophosphate and the particulate and dissolved fractions …

The Big Sioux River transported 418,640 x 10 3 m3 of water, 776,880 kg TP, 599,590 kg TON, and 5,419,580 kg TOC during the study-year. Six Mile Creek transported 23,900 x 10 3 m 3 of water, 52,040 kg TP, 43,580 kg TON, and 327,860 kg of TOC. The transport of water and nutrients in Six Mile Creek per square kilometer of …
Groundwater - Surface Water Integration Study In The Grand Prairie Of Arkansas, Carl L. Griffis
Groundwater - Surface Water Integration Study In The Grand Prairie Of Arkansas, Carl L. Griffis
Arkansas Water Resources Center Technical Reports
A mathematical model of the Quaternary Aquifer of the Grand Prairie, Arkansas was developed and used to evaluate a variety of methods of artificially recharging this aquifer. In addition, the model was used to evaluate the impact of various levels of water management and the probable movement of artificially recharged water in the aquifer. Improved water management and the use of recharge wells were the two alternatives that showed the most promise as potential solutions. The rate of movement of recharged water was determined by the model to be 300 ft./year under a gradient of 16 ft./mile.

Phytoplankton Successions And Lake Dynamics In Las Vegas Bay, Lake Mead, Nevada, Ervon R. Koening, Richard W. Tew, James E. Deacon
Publications (WR)
Phytoplankton successions, applications of the general growth equation, and physical measurements have been employed to investigate events occurring at the interface between industrial and sewage effluent contained in Las Vegas Wash and the waters of Lake Mead, Nevada. The data indicate that the entering waters tend to form a density current interrupted at intervals by dynamic effects generated in the lake. The dynamic relationships described here for the spring months suggest that a much more thorough understanding of physical, chemical and biological interactions is necessary to permit solution of the numerous problems of Las Vegas Bay discussed or alluded to …

Bulletin No 3867 - Water For Agriculture. Clearing Cloudy Or Coloured Water, N. E. Platell
Bulletins - 3000 - 3999
THE suspended material in most water supplies is generally clay, although sometimes organic matter and materials precipitated from solution, such as hydrated iron oxides, may be present. Coloured waters are those waters that are still coloured, due to dissolved coloured matter, after suspended material has been removed. Some coloured waters such as those found in swampy areas may be entirely free of suspended material.
The amount of clay or colour present is mainly of concern where the water is used for household purposes. Only rarely is the clay or colour present in such quantities that the water is undrinkable for …

The Delaware Limestone (Middle Devonian) Of Southwestern Ontario, Canada, Robert F. Diffendal Jr.
The Delaware Limestone (Middle Devonian) Of Southwestern Ontario, Canada, Robert F. Diffendal Jr.
School of Natural Resources: Faculty Publications
The Delaware Limestone of southwestern Ontario was originally called a part of the Corniferous Limestone by Murray (184.3-53). Since that time the same outcroppings have been designated, either wholly or partially, as the Onondaga Formation, the Big Lime, Delaware Limestone, Norfolk Formation, Dundee Limestone, Columbus Limestone, and the Dundee (= Delaware) Limestone. As recently as 1971 the names Dundee Limestone and Delaware Limestone were used for the same formation.
Hand specimen and petrographic study of samples from nineteen localities in southwestern Ontario indicates that the limestones of the formation exposed on the Niagara peninsula are intermediate in type between the …
Saltmarsh Ecology And Resource Protection, Gerard Desire Blais Jr.
Saltmarsh Ecology And Resource Protection, Gerard Desire Blais Jr.
Marine Affairs Theses and Major Papers
A panoramic lack of conservation education has produced a populace largely unaware of the value of marshland resources or measures for their protection. In a relentless era of ecological abuse, wetlands and salt marshes rank with endangered animal species in the quantitative loss culminating in extinction. Challenged continually by the relentless sea and exploited by unsound attempts at development, management, or even conservation, the efficiency of the marshlands is decreasing with each successive invasion. There is a demonstrated reduction in biological productivity, flood control, and water quality in areas where dredging, draining, and filling of marshes has taken place.
