The Certified Strains Of Subterranean Clover : Their Origin, Potential Use And Identification, B J. Quinlivan, C. M. Francis, M. L. Poole

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

SUBTERRANEAN CLOVER originated in the countries surrounding the Mediterranean Sea and in parts of Western Europe.

Therefore it is not surprising that it grows well in the agricultural districts of Western Australia, for these regions have a typically Mediterranean climate with cool wet winters and hot dry summers.

Wheat In Development Programmes For New Esperance Farmers, R J. Doyle, G. D. Oliver

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

IN the December, 1967, issue of the Journal of Agriculture, we reported on five development budgets for the Esperance region.

The aim of the exercise was to find out if a new settler concentrating on sheep, with $20,000 available for development after acquisition of land, could make a reasonable living for himself and his family while developing his farm.

The Ord River Regeneration Project. 2. Dealing With The Problem, K Fitzgerald

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

THE PROGRAMME of protective and remedial work being undertaken in the Ord River catchment area had as its major objective the re-establishment of perennial vegetation, as a means of controlling erosion and reducing the silt load of the rivers. It is now in its seventh year of operation.

Entering The Egg Industry With Laying Cages, W Ward

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

DEPARTMENT of Agriculture Bulletin 3579, "Entering the Egg Industry with Laying Cages", by W. Ward, examines various aspects of the cage system of housing laying hens.

This system is by far the most popular method of housing layers, with 90 per cent, of new farms using cages and many daep litter farms now converting to cages.

Space Requirements For Pullets And Layers On Litter, A H. Lean

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

UNEVEN growth, cannibalism, weakened resistance to disease, unsanitary conditions and poor production commonly arise from failure to provide sufficient floor, feed and watering space for pullets and layers.

Bulletin No 3547 - Kimberley Research Station - Progress Report 1968, Western Australian Department Of Agriculture

Bulletins - 3000 - 3999

Rivers flowing to the Gulf of Carpentaria and the Timor Sea have been estimated by hydrologists to carry about three times the water transported annually over the Murray drainage system and the South Eastern slopes which, together, comprise the highly settled agricultural areas of South Eastern Australia.

In 1945, the North Australian Development Committee recommended research in the Ord-Victoria rivers region as a first step toward ultimate agricultural development of this Northern potential and, in 1946, the Kim- berley Research Station commenced operations under the joint control of the Commonwealth Scientific and Industrial Research Organization and the Western Australian Department …

Effects Of Dieldrin On Reproduction Of Penned Hen Pheasants In The Second Generation, William Lyman Baxter

Electronic Theses and Dissertations

Effects of dieldrin on penned hen pheasants (Phasianus colchicus) which were the offspring of hens receiving encapsulated dieldrin the previous year were measured. Hens produced by the previous year's control group received 0, 6, 8, or 12 mg of dieldrin per week for 14 weeks. Hens from treated groups received 0 or 6 mg per week. Effects of dieldrin were evaluated by influences upon reproductive success. Mortality occurred in all groups receiving dieldrin, and appeared to be correlated with a reduction in egg production. Dieldrin lowered egg production by reducing food consumption in the 12 mg group and two groups …

Snapping Turtle Life History On Lacreek Refuge, South Dakota, Donald Arthur Hammer

Electronic Theses and Dissertations

Investigations of the snapping turtle population on Lacreek National Wildlife Refuge in south-central South Dakota were conducted during 1965-67. Turtles captured by trapping, “hooking”, boxing nests and catching nesting females were measured, marked and released. Turtles were marked by toe-clipping, routing, flagging, and tagging. Attaching a metal tag with a “pop-rivet gun” was the most successful marking technique. Molluscs (95 percent frequency) and vegetation (91 percent frequency) were the most important food items of 22 turtles captured on Valentine Refuge in north-central Nebraska. Bird remains were found in 23 percent of the stomachs. Recapture of marked turtles indicated that individual …

Life History And Ecology Of The Black-Footed Ferret In The Wild, Conrad N. Hillman

Electronic Theses and Dissertations

Twenty-one black-footed ferrets (Mustela nigripes) were observed at six different locations in southwest South Dakota between April 1966, and September 1967. All observations were made on black-tailed prairie-dog (Cynomys ludovicianus) towns from 15 to 100 acres in size. Because of the proximity of towns inhabited by ferrets, it was possible that individual animals were observed in more than one location. Three litters of ferrets were studied. Young ferrets were most active during early morning and late evening hours. Ferrets remained as a group until early fall when dispersal evidently occurred. Young ferrets accepted live-tethered and dead prairie dogs, mice, cottontails …

Food Habits And Energy Utilization Of Badgers, Grant K. Jense

Electronic Theses and Dissertations

A study was initiated in 1966 to determine food habits and energy utilization of badgers. Digestive tracts were collected in eastern South Dakota from November 1966 to November 1967. A male and a female badger were used for two energy-balance and three digestion trials. Ground squirrels, mice and rabbits were found to be the most important mammal foods eaten. Birds and eggs were only eaten during spring and summer. Toads and grains were important fall foods. Insects were eaten throughout the year but usually only in trace amounts. However, when available, badgers ate large quantities of beetles and ground-nesting bees. …

A Survey Of Pollution On Selected Streams In The Black Hills Of South Dakota, Thomas J. Jurgens

Electronic Theses and Dissertations

Seven Streams in the Black Hill of South Dakota were surveyed to determine the influence of suspected sources of pollution on these streams. The sources of pollution included both sewage treatment plant effluents and mining wastes. A comparison of the benthic fauna community below a pollution source to that above it was the primary basis for evaluating the effect of the pollution source on the stream. The results of the benthic fauna samples indicated that the streams surveyed were being polluted. The degree of pollution of each stream was also indicated by these results. Chemical analysis were sued to verify …

Evaluation Of The Legal Institutions Of Diversion, Transfer, Storage, And Distribution Of Water In Kentucky, A. Dan Tarlock

KWRRI Research Reports

In 1966 Kentucky enacted a water use regulation statute which makes :important modifications in the common law doctrine of riparian rights by authorizing the state to grant permits for the use of water. The permit system is primarily designed to allow the state to gather the information necessary to conduct long range planning studies. However, the permit system can also be used to apportion water among competing users. The report examined the common law of riparian rights to determine how KRS Ch. 151 had modified it and analyzed some of the legal problems which could arise in the administration of …

Esthetic And Recreational Potential Of Small Naturalistic Streams Near Urban Areas, John A. Dearinger, Kenneth R. Harper, L. Douglas James

KWRRI Research Reports

The purpose of this study was to find a way to evaluate the esthetic and recreational potential of small streams and their watersheds. Research was limited to naturalistic streams with drainage areas under 100 square miles and located within 25 miles of a city. A methodology, based on some previous work of the U.S. Soil Conservation Service and the principles or concepts of terrain analysis, land use planning, value Judgment philosophy and the economics of outdoor recreation, was developed and applied in detail to two streams (Boone and Jessamine Creeks) near Lexington, Kentucky.

Evaluations were made of the streams' potential …

Distribution And Mortality Of Saskatchewan-Banded White-Fronted Geese, Harvey W. Miller, Alex Dzubin, John T. Sweet

Nebraska Game and Parks Commission: Staff Research Publications

At its annual spring meeting in 1959 the Technical Committee of the Central Flyway Council recognized a decreased population of the white-fronted goose (Anser albifrons). The recorded harvest in Canada and the United States had exceeded the estimated wintering population in some years. After summarizing records for the Central and Mississippi Flyways the Committee found them inadequate for management and to help fill this void, recommended banding on local concentration areas including Saskatchewan.

Coleambally Irrigation Area: Herds, Crops, Fruit, Lydia Belthuis

Journal of the Minnesota Academy of Science

Coleambally, a new irrigation unit, to the south of the Murrumbidgee Irrigation Area in Australia, has come into operation since 1960. It is the first land to receive water from the large Snowy Mountain power and water storage development in southeastern New South Wales. This district of some 139,000 acres now produces rice, wheat, hay, vegetables, fat lambs and wool. When all Snowy Mountain structures are completed and reservoirs filled, the irrigation area will be more than tripled in size.

Movements And Behavior Of Pheasants During The Breeding Cycle As Determined By Radio-Tracking, Thomas L. Kuck

Electronic Theses and Dissertations

Behavior and movement studies were carried out on the Rifle-Calahan Study area, Sanborn County, South Dakota, in 1965 and 1966. Objectives of the study were to evaluate radio telemetry techniques, determine the territorial area and home range of the hen and cock, study the behavior pattern of hen and cock in the harem makeup, determine the distance traveled by the hen when attracted to the harem, determine if the hen nests in the immediate area of the crowing territory, and study the behavior of the hen while nesting and caring for the brood. Twenty adult pheasants (16 hens and 4 …

A Study Of The Removal Of Pesticides From Water, James David Whitehouse

KWRRI Research Reports

The purpose of this study was to investigate some of the properties of pesticides as they exist in water, and to determine the effectiveness of several water treatment processes in the removal of pesticides from water. Among the pesticides investigated were malathion, DDT, aldrin, dieldrin, captan, benzene hexachloride (BHC), 2,4-D, and 2,4,5-T. The water treatment processes included aeration, chemical coagulation, adsorption on activated carbons and clays, and foam separation.

The removal of pesticides from water by aeration was found to be significant. Dieldrin was removed almost 100 percent, while aldrin, DDT, and BHC were removed to a lesser extent. 2, …

Water Quality Study Of Lake Mead, Dale A. Hoffman, Paul R. Tramutt, Frank C. Heller, Bureau Of Reclamation

Publications (WR)

This report presents Lake Mead Water quality data obtained from 1964 to 1966. The effect of filling Lake Powell on the water quality of Lake Mead is evaluated. General limnological principles and the present limnology of Lake Mead are discussed. Lake Mead has a warm monomictic annual temperature cycle characterized by summer stratification, fall overturn leading into a continuous circulation throughout the winter; temperatures never fall below 39 deg F (4 deg C). During stratification, lower dissolved oxygen values were recorded in the thermocline than in the epilimnion and hypolimnion. Mineral content increases from the upper to the lower end …

Aircraft As A Means Of Baiting Ground Squirrels, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 3rd (1967)

Aircraft might soon become an important tool for baiting ground squirrels (Citellus beecheyi beecheyi and C. b. fisheri) on California rangeland. Until recently, almost all squirrel control has been conducted by the hand-baiting method, with grain bait scattered from horseback in spoon-size amounts near squirrel burrows. Ground squirrels are considered a major pest of rangeland in many parts of the West. They not only compete with livestock for forage but also are responsible for substantial losses to cereal and other crops. The magnitude of the problem is exemplified by the fact that, in California alone, over 6,000,000 gross acres of …

The Current Status Of Plague In California, Keith F. Murray

Vertebrate Pest Conference Proceedings: 3rd (1967)

At the first Vertebrate Pest Control Conference in 1964, I traced the history of plague control in California and outlined a revised approach, based on newer concepts of plague ecology. In our state of relative ignorance, this required a number of unproved assumptions about plague occurrence in California that verged on crystal ball gazing. These were principally that (1) plague persists in relatively resistant rodent species in certain favorable locations, (2) ground squirrels and chipmunks experience periodic epizootics, but are not permanent reservoirs, (3) plague "foci" of the past were merely sites of conspicuous epizootics, they did not necessarily correspond …

The Current Status Of Wild Animal Rabies In California, George L. Humphrey

Vertebrate Pest Conference Proceedings: 3rd (1967)

During the 15-years 1952-1966, a total of 3504 cases of animal rabies were reported in California, an average of over 230 cases annually (Table 1). Of these 3504 cases, 2255 or nearly 65 percent were reported in wildlife species. An estimate sometimes used is that for every reported or recognized case of wild animal rabies, 10 cases probably occurred without recognition. Using the foregoing "rule-of-thumb", it can be hypothesized that during the 15-years 1952-1966, an estimated 22,600 or more cases of wildlife rabies occurred in California. The addition of the over 1200 cases of rabies reported in domestic animals during …

Good Practice In Vertebrate Pest Control, Philip J. Spear

Vertebrate Pest Conference Proceedings: 3rd (1967)

Good practice in pest control is a responsibility of several elements in our democratic, free-enterprise society. Most notably, these are: (1) the general public, (2) responsible government agencies and (3) industry. Before I comment about the responsibilities of each of these three groups, let me tell you about the work of structural pest control operators and their interests in vertebrate pest control. The pest control industry which I discussed in detail at the Second Vertebrate Pest Control Conference (1) continues to grow and expand its fields of activity. At the present time, it is our estimate (2) that 26,700 persons …

Review Of Animal Repellents, Jack F. Welch

Vertebrate Pest Conference Proceedings: 3rd (1967)

A review of the literature on this subject reveals there is considerable confusion regarding the meaning of the word "repellent" as it relates to animal control. Some people make a liberal interpretation and include any material or device that will alter the pattern of activity of an animal through response to sight, sound, taste, odor, or touch. Although such an interpretation may be valid, for this paper I would like to confine my discussion to "chemical repellents" -- materials that, when applied to seeds, plants, or other materials being damaged by animals, will reduce depredation through taste, odor, or possibly …

Animal Control - Progress, Problems And Professionalism, Robert M. Sutton Jr.

Vertebrate Pest Conference Proceedings: 3rd (1967)

I want to take some liberty with my title as it is rather general. Specifically, I want to discuss some matters of mutual concern, and I will touch lightly upon our Division's activities and the status of our reorganization and redirection. In so doing, I do not propose to rehash the several talks that have been previously given and the papers written on what's new in animal control. Rather, I shall use this opportunity to examine a few problems that confront our Division, and in many cases, that confront everyone concerned with vertebrate pest control. We are now, in a …
