Conservation Of The National Estate, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

In 1973 the Australian Government established a Committee of Inquiry under Mr. Justice R. M. Hope to inquire into the National Estate. Under its terms of reference the Committee was to assess the nature and condition of the National Estate and the measures which were being and should be taken for its preservation and enhancement.

Officers of the Department of Agriculture recognise that there are basic natural resources such as land, water, gene material and ecosystems which are essential elements of the National Estate held in trust by successive generations.

In a submission to the Inquiry, matters of particular concern …

Nitrogen Fertilisers For Pasture Production, Walter Jacob Cox, K Hawley

Journal of the Department of Agriculture, Western Australia, Series 4

At current prices nitrogen fertiliser is not an economic substitute for good clover pastures, but it can supplement the system by increasing nitrogen supply at peak growth periods. It can also provide useful increases in pasture production at critical feed times. Nitrogen usage for pasture production is still in the experimental stages and small areas should be tried before large-scale application.

Pheasant Reproduction And Survival As Related To Agricultural Fertilizer Use, Lawrence Francis Fredrickson

Electronic Theses and Dissertations

Wing-clipped wild pheasants (Phasianus colchicus) were stocked in 1-acre and 0.5-acre pens having oat and bromegrass cover in 1972 and 1973 to test effects of fertilizer (Formulations: 34-0-0, 18-46-0, 0-46- 0, and 0-0-60) on pheasant reproduction and survival. One-half of the pens were fertilized with the recommended rate of pelleted fertilizer and the other half without fertilizer. Complete nest searches in July showed that nesting success was not significantly different (P>0.05) between treatments for both years. No significant difference (P>0.05) was found in clutch size or in number of ovulated follicles from control and experimental hens. Significantly more …

Electronic Theses and Dissertations

The learning behavior of penned white pelicans (Pelecanus erythrorhynchos) was studies 2 August to 5 October 1972 using a swimming pool – Y-maze apparatus in an operant conditioning experiment. The experiment consisted of three consecutive phases: trial-and-error learning, extinction, and relearning. Three groups of nine pelicans each were studied: a polychlorinated biphenyl (PCE) treated group, a DDT, DDD, DDE treated group, and a Control group. The object of this study was to determine the effect of PCB and DDT, DDD, DDE on the learning ability of penned white pelicans. Control, PCB, and DDT groups of penned white pelicans learned to …

Habitat Preferences And Food Habits Of Striped Skunks In Eastern South Dakota, Melvin S. Moe

Electronic Theses and Dissertations

Habitat preferences of striped skunks (Mephitis mephitis) in Brookings County, South Dakota, were determined rom the relationship of nighttime roadside indices to 25 habitat variables of 277, 1-square mile plots. Winter tracking was also conducted. Skunks were collected on the study area in 1972-1972, and contents of 59 stomachs and 63 colons were studied to determine food habits. Indices of prey abundance in different habitat types were obtained from snap-trap surveys. The 25 variables accounted for 14.9 percent of the variation in skunk numbers. The relationships of three of these variables to skunk numbers were significant (P<0.05). The significant variables and the variation accounted for by each were: (a) number of areas of idle grassland, 6.3 percent; (b) number of rockplies, 1.5 percent; and (c) acreage of idle grassland, 1.3 percent. Idle grasslands were the main activity centers of skunks tracked during the winter. Food habits were analyzed for the periods March-April, May-June, July-August, and September-November. Insects were the most frequently found food item in al time periods except March-April, during which mammals occurred more frequently. Mammals made up the largest volume of food in March-April and May-June. Amphibians made up the greatest volume in July-August, while amphibians, mammals, and insects were found in nearly equal volumes in September-November. Bird remains occurred during all time periods. Eggs were found in May-June and July-August. Meadow voles (Microtus spp.), the most frequent mammalian food item during all time periods, were common only in habitat types having heavy residual cover. Idle grassland is an important nestling cover for gamebirds and waterfowl. Since the number of areas of this cover type apparently has a stronger relationship with skunk numbers than its total acreage, grassland nesting cover might best be managed in large, homogeneous blocks. Areas managed in this way would probably support lower skunk densities than more diverse areas containing equal acreages of idle grassland, thus reducing nest predation by skunks. Skunk control programs should be most efficient when centered around idle grassland and rockplies.

Influence Of Vegetation On The Distribution Of Small Mammals On A Waterfowl Production Area, Douglas A. Searls

Electronic Theses and Dissertations

. A study was conducted on a Waterfowl Production Area in Brookings County, South Dakota in 1972-73 to determine the distribution and abundance of small mammals. Three cover types, reseeded native grassed, brome-alfalfa, and bluegrass, were studied. Meadow voles (Microtus pennsylvanious), and deer mice (Peronyscus maniculatus) were captured most frequently. Jumping ice (Zapus hudsonius), masked shrews (Sorex cinerius), short tailed shrews (Blarins brevicauda), grasshopper mice (Omychomys leucogaster) and house mice (Mis musculus) were also taken. The bluegrass association had the highest number of small mammal captures and the reseeded native grass association has the least. There was no significant difference …

Sensitivity Of Vertebrate Embryos To Heavy Metals As A Criterion Of Water Quality, Phase I, Wesley J. Birge, John J. Just, Albert G. Westerman, A. Duane Rose

KWRRI Research Reports

Avian, amphibian and fish embryos were given continuous treatment with inorganic mercury, methyl mercury, cadmium and lead, to determine the sensitivity of embryogenesis to metallic poisoning. All metals produced substantial degrees of lethality and/or gross anatomical anomalies at 10 ppb or less. Treatment with inorganic mercury at 10 ppb produced 100% kill of frog embryos. Chick and rainbow trout embryos suffered 10-20% lethality when exposed to 1 ppb of either inorganic or methyl mercury. Lead and cadmium at 1 ppb produced 24-32% lethality in chick embryos. No significant differences were observed in the embryopathic effects of inorganic or methyl mercury. …

Rate Of Growth As A Method Of Assessing Water Quality, George L. Johnston

Masters Theses

A study of the Embarras River basin was conducted to determine if rate of growth could be used as an indicator of water quality. Six species of sucker were collected from five locations using hand seines and electrofishing gear from December 1970 to December 1971. Tests of eighteen water quality parameters were conducted from November 1970 to November 1971.

The fish were measured and scale samples taken. The rate of growth of the fish taken at the five stations was analyzed and compared using the single classification analysis of variance. Condition factors were also compared.

Although there was some difference …

Size And Growth Of The Eyes Of The Troglobitic Salamander Typhiotriton Spelaeus, Joseph C. Besharse, Ronald A. Brandon

International Journal of Speleology

The eyes of larval T. spelaeus grow by negative allometry, but in allometric coefficients they are not greatly different from E. lucifuga. The major differences in eye size, both absolute and relative to body size, between T. spelaeus and E. lucifuga are established prior Io the larval growth period. The eyes of T. spelaeus cease to grow at metamorphosis and are reduced in size thereafter. In addition, there is increased individual variability and bilateral asymmetry of eye size in adult T. spelaeus compared to both adult E. lucifuga and larval T. spelaeus. This variability, expressed as relative dispersion …

Electromagnetic Fields In Water Treatment, Robert H. Fagan

Retrospective Theses and Dissertations

Properties and characteristics of colloidal systems are reviewed with a discussion of colloid systems to be found in natural and wastewaters. Current electric and magnetic field theory are reviewed and summarized to provide practical application of the theory to engineering problems in the environmental field. Literature of colloidal reactions to electrical and magnetic fields is discussed and reviewed to ascertain areas of potential application of electric and magnetic phenomena to natural and wastewater treatment systems having objectionable colloid suspensions. It is concluded that application of electrical fields (electrophoresis) does not currently hold much promise for practical applications in water treatment …

Evaluative Study Of A Proposed Municipal Pyrolysis Installation, Leon Breckenridge

All Master's Theses

This paper discusses an alternative to sanitary landfills as a method of disposing of municipal solid waste. The alternative means is a pyrolysis-gasification process for the disposal of solid wastes and the production of energy in the form of a gas of relatively low energy content.

Characteristics of typical municipal solid wastes are discussed. A discussion of the pyrolysis process is included along with other pertinent technical information. A method for utilization of the energy produced from pyrolysis is presented.

The Effect Of An Administration Of Audio-Visual Aids On The Attitudes Of Geometry Students Toward Mathematics, Kirk Quistorff

All Master's Theses

This paper presents an experiment to determine the effect of an administration of audio-visual aids on the attitudes of geometry students. It was hypothesized that the experimental group would make a significant improvement in their attitude toward mathematics. The control group had eight-two students and the experimental group had forty-six students. In the control class no audio-visual aids other than the overhead projector were used. The results did not verify the hypothesis and the author concluded that more research was needed.

The Place Of Lucerne In Western Australian Agriculture, N J. Halse, C. M. Francis

Journal of the Department of Agriculture, Western Australia, Series 4

Lucerne, the world's most important fodder legume, has never won largescale acceptance in West Australian farming, largely because of our success with productive subterranean clover pastures. But recent disease problems on sub. clover stands have led to greater interest in alternative species, especially lucerne, for higher rainfall areas.

This article summarises our knowledge of lucerne establishment and management in W.A. and reviews current research aimed at achieving better results from lucerne.

A Study On Two Iodine Containing Peptides Isolated From Porcine Thyroglobulin, Frederick E. Bishop Jr.

Masters Theses

"Two iodopeptides were isolated from thyroglobulin that had been digested with trypsin by paper electrophoresis and paper chromatography. The amino acid analysis demonstrated that the amino acid compositions were similar. The N-terminal amino acid of both iodopeptides was shown to be leucine. The amino acid sequence of one of the iodopeptides was determined by the Edman degradation method and digestion with the enzyme Carboxypeptidase A. The sequence was shown to be: NH₂-Leu-Asn-Ala-Ser-Glu-MIT-Gly-Thr-Ser-Gly-COOH. Other workers have shown that synthetic tyrosyl peptides with the sequence Glu-Tyr are iodinated by the thyroid peroxidase enzyme with a greater specificity than other tyrosyl peptides. This …
