An Epornitic Of Avian Cholera In Waterfowl And Common Crows In Phelps County, Nebraska, In The Spring, 1975, Joseph Zinkl, Norm Dey, Joseph Hyland, James Hurt, Kenneth Heddleston
Nebraska Game and Parks Commission: Staff Research Publications
In the spring of 1975, many species of waterfowl and common crows (Corvus brachyrhynchos) were found dead in Phelps County, Nebraska. About 25,000 waterfowl and at least 3,000 crows died in the epornitic. Few waterfowl were seen dying, but the crows experienced a chronic illness during which they became debilitated and were lethargic and dyspneic. Gross and microscopic lesions in the waterfowl were typical for acute avian cholera. The crows had dank, firm areas within the lungs, a loosely adhered yellow fibrous material in the pericardial sac and air sacs and, occasionally, liver abscesses. Microscopically, focal punulent pneumonia …

Nebraska Game and Parks Commission: Staff Research Publications
During fall 1974, approximately 1,000 to 1,500 common crows (Corvus brachynhvnchos) died of aspergillosis in south-central Nebraska. The binds were debilitated, lethargic and dyspneic. On necropsy, typical lesions of aspergillosis were found in the lungs and air sacs. Histopathologic examination revealed granulomatous lesions around fungal hyphae in the respiratory system.
A Model To Investigate The Influence Of Suspended Sediment On The Mass Transport Of A Pollutant In Open Channel Flow, Raymond Scott Chapman
A Model To Investigate The Influence Of Suspended Sediment On The Mass Transport Of A Pollutant In Open Channel Flow, Raymond Scott Chapman
Civil & Environmental Engineering Theses & Dissertations
The environmental impact of the transport of pollutants in open channel flow has for many years been of interest due to the continuous introduction of heavy metals, pesticides, herbicides, and other foreign substances into natural waterways. In order to fully understand this transport process, it-is necessary to examine the significance of its individual components. In the present study an explicit two-dimensional finite difference model, designed to investigate the influence of suspended sediment on the pollutant transport process, is presented. Specific attention is directed toward examining the role of suspended sediment in 1) the turbulent vertical transport mechanism in a stratified …

Occurrence Of Four Major Perennial Grasses In Relation To Edaphic Factors In A Pristine Community, Edgar F. Kleiner, K. T. Harper
Occurrence Of Four Major Perennial Grasses In Relation To Edaphic Factors In A Pristine Community, Edgar F. Kleiner, K. T. Harper
Canyonlands Research Bibliography
The ecology and phytosociology of a virgin grassland community (Virginia Park, Canyonlands National Park, Utah) have been investigated. Based on the use of C √ó F index, Hilaria jamesii and Stipa comata are the most abundant of the four major perennial grasses. Oryzopsis hymenoides and Sporobolus cryptandrus are less abundant in decreasing order. The sites dominated by Hilaria are characterized by soils with finer texture, slightly warmer average temperature and higher surface K+ and organic matter compared to sites dominated by Stipa comata. In addition, frequency of both vascular and cryptogamic species is greater on sites dominated by Hilaria.
Saltland And What To Do About It, C V. Malcolm
Saltland And What To Do About It, C V. Malcolm
Journal of the Department of Agriculture, Western Australia, Series 4
Saltland can be conveniently divided into three main types on the basis of cause. Within each type their is great variation, and the types may merge or overlap.
The three aims of a saltland treatment programme are; reduce the groundwater levels or seepage flows as much as possible,reduce the capillary action which brings salt to the surface, and to revegetate the soils with the most useful plants that can survive.
Soil Properties In Relation To Cryptogamic Groundcover In Canyonlands National Park, Edgar F. Kleiner, K. T. Harper
Soil Properties In Relation To Cryptogamic Groundcover In Canyonlands National Park, Edgar F. Kleiner, K. T. Harper
Canyonlands Research Bibliography
A comparative study was made of the soils of a virgin grassland and an adjacent grazed area in Canyonlands National Park. Soils from the virgin site were finer textured than those of the grazed area, and the surface 5 cm contains a significantly lower amount of calcium. In addition, the surface 5 cm of the virgin site contains significantly greater amounts of phosphorus, potassium, and organic matter. Subsurface soils in the two parks are less dissimilar. Cryptogams on the virgin grassland appear to have an important influence on chemical characteristics of the surface 5 cm of soil. The difference in …

The European Wasp : A New Threat To W.A, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
The European wasp was detected in Western australia for the first time in January and February 1977 in the metropolitan suburbs of Mosman Park, Cottesloe and Attadale.
So far it has only been found within an area of 8 km radius from Fremantle but the outer boundries of the infestation are still uncertain.
It is Department of agriculture policy to eradicate the European wasp, if possible, and to destroy all nests detected.
P.W.D. Supplementary Public Water Supply Schemes, J E. Davis
P.W.D. Supplementary Public Water Supply Schemes, J E. Davis
Journal of the Department of Agriculture, Western Australia, Series 4
Shallow wells and soaks with very limited yields were the principal water sources for the early settlers.
Hundreds of such wells were constructed by the Public Works Department in remote areas.
In the early 1930s major development of water supplies from rock catchments was begun in the central wheatbelt.
After the war, larger and more effective earth moving equipment became available. The Public Works Department rehabilitated many old excavated dams as well as constructing new ones.
Roaded catchments were also developed during this post-war period. many farmers took advantage of Public Works Department technical advise and hired a P.W.D. grader …

Journal of the Department of Agriculture, Western Australia, Series 4
The Comprehensive Water Supply Scheme has been a great boon to the agricultural area, and it has received strong support from all political parties. The Scheme has been responsible for increased prosperity of country towns, the decentralisation of industry, and general improvements in the standard of living.
This is a look at the development of the Scheme.

Native Plants : Water Savers In The Garden, K S. Cole
Journal of the Department of Agriculture, Western Australia, Series 4
The climate of Western Australia may be one of the best in the world for people but it is a difficult one for many of our imported, and common garden plants. as a consequence, some 70 per cent of our summer water usage is for gardens and lawns.
This is not the sort of statistic that we should accept easily or happily.
There is a solution to this problem: a new approach to home gardening is required.
The new garden is based on W. A.'s own colourful native plants, which are adapted to mild winters, hot dey summers and poor …

Effects Of Soil Heterogeneity On One-Dimensional Infiltration, Charles Courette, Roland W. Jeppson
Reports
A parameter study for heterogeneous infiltration was performed employing a one-dimensional computer program. Soil heterogeneity was defined by linear variations of soil parameters. From the solutions obtained, the instantaneous and accumulative infiltration rates were correlated versus the rate in which the parameters varied in the soil profile. The end result being coaxial graphs from which a relative infiltration rate may be obtained by inputting time and the rates of change of various soil parameters.

Some Basics Of Marron Production, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
marron are native to the South-West of Western Australia, and are keenly sought by inland fisher-men. However, supplies do not equal the apparent demand.
One solution is to cultivate marron in farm dams, or more intensively as a commercial enterprise.
This article suggests a few guidelines for marron production.
Effect Of Deforestation By The Douglas-Fir Tussock Moth On The Quality Of Streamflow And Stream Productivity Parameters, Martin Ed Hicks
Effect Of Deforestation By The Douglas-Fir Tussock Moth On The Quality Of Streamflow And Stream Productivity Parameters, Martin Ed Hicks
All Master's Theses
The purpose of this study was to determine if deforestation by a recent outbreak of Douglas-fir tussock moth and logging of such deforested timber has had any effect on stream water quality. To determine this, seven different watersheds of three types were examined. The three types were: undamaged watersheds as controls, watersheds with deforestation and watersheds with deforestation where the timber was subsequently logged. Twenty-four variables were used to determine water quality. Included were seven biological and seventeen chemical variables.
In general, the results indicate only seasonal fluctuations and differences between watersheds due to inherent properties of individual watersheds. Increased …

Farm Dams In The Wheatbelt, I A F Laing
Journal of the Department of Agriculture, Western Australia, Series 4
Of the estimated 76 000 farm dams in the wheatbelt, about 8 per cent either leak or are salt affected. The remaining 70 000 dams are capable of holding water for livestock use and can be regarded as sercicable dams.
A great many of the serviceable dams are unreliable water supplies due to the combined effects of lack of runoff from catchments, shallow depth of storage and small size of storage in relation to expected demand from livestock and evaporation loss.

Design Standards For Farm Surface Water Supplies, J L. Frith
Journal of the Department of Agriculture, Western Australia, Series 4
Design is usually concerned with getting adequate return from limited recources. Farm dams which dry up represent dam failure. Less seriously, so too do dams which, although not drying out, never fill; they waste a recource.
Economics Of Farm Water Supplies, P P. Eckersley
Economics Of Farm Water Supplies, P P. Eckersley
Journal of the Department of Agriculture, Western Australia, Series 4
The economics of farm water supplies can be studied in two ways. One is to compare the costs of alternative ways of supplying a specified quantity of water to a farm. Another is to calcu;ate how mucha farmer can afford or will pay for a water supply.
I propose to look at these questions from the point of vieew of an eastern wheatbelt farmer, assuming that he must pay the full costs of any water supply provided for his property.

Groundwater In The Wheatbelt, E P. O'Driscoll
Journal of the Department of Agriculture, Western Australia, Series 4
In general six factors affect the occurence of groundwater; rainfall, topography, rock type, rock structurs, vegetation, and local evaporation.
Variation in even one of these can affect the potential yield of a bore or well, the groundwater salinity, and even whether any groundwater occurs at all.
