Wallaby Control In The Kimberleys, C D. Gooding

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

EXPERIMENTS aimed at controlling sandy wallabies along the Fitzroy River frontage were started in 1952 by officers of the Agriculture Protection Board.

This work was undertaken in response to requests for assistance from some of the station owners and managers between Derby and Fitzroy Crossing.

Milking Routine, G R. Olney

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

IT is well known that the condition of the milking machine is important for efficient and hygienic milking, but even with a machine in good condition good management during the milking process plays a leading part.

Water For Agriculture. 6. Control Of Algae In Water Supplies, R C. Gorman

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

ALGAE are primitive forms of plant life that are common and normal in surface waters. They are fonnd in every water supply exposed to sunlight.

Their presence is not normally detectable until there are enough of them to make their presence obvious.

Rabbit Fumigation, C D. Gooding

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

Not all poisons act by absorption from the alimentary tract or through the skin, the fumigants are a big group of poisons used in pest control which act on the animal after being absorbed through the lungs.

FUMIGATION as it is now used in Western Australia is not always an economical way of treating whole farm properties. It should only be used on its own in areas where it is impossible to use other more permanent methods such as warren destruction.

The Archeology Of The Lime Creek Site In Southwestern Nebraska, E. Mott Davis

University of Nebraska State Museum: Staff and Affiliates, Publications

The Lime Creek site is a stratified Early Lithic (Paleo-Indian) camp site buried in the Terrace-2A alluvial fill of a valley in the dissected loess plains. Geological correlations indicate an early Valders (Wisconsin- IV) date. A radiocarbon date (No. C-471) of 9524 B.P. from just below Lime Creek I, the lowest occupation zone, must be taken only as a minimal possible age for the site. The animal bones in Lime Creek I are primarily of pronghorn and beaver, whereas those in Lime Creek III, the highest occupation zone, are exclusively of bison. The change in hunting patterns seems due to …

Ecology Of Spring Fed Salt-Marshes, Eric George Bolen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Any marsh is a distinctive land-form of varied interest. To the agriculturist it is wasteland to be reclaimed; to the naturalist, a habitat of aesthetic value. To the ecologist, however, a marsh represents a complexity of vegetation under the influences of many and often inseparable factors. It becomes a place of challenging study.

Vermin Control Research In Western Australia 1952-1962, C D. Gooding

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

Ten years ago this month the Agriculture Protection Board of Western Australia began setting up a section within its Vermin Control Branch to tackle some of the scientific aspects of vertebrate pest control.

C. D. Gooding, B.Sc. (Agric), reviews the first 10 years of vermin control research work in Western Australia.

Webworm And The Weather, J A. Button

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

FOR many years farmers have remarked on the cyclic occurrence of webworm outbreaks in their cereal crops.

Webworm, the State's most serious pest of cereals, has frequently assumed a role of major importance for one or two seasons, and then not been troublesome for a number of years.

A research programme being carried out by the Entomology Branch aims to give a better understanding of the effects of weather conditions on the seasonal incidence of webworm, and should lead to more effective control of this pest.

Grazing To Control Pasture Composition, R A. Bettenay

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

APART from grazing management, there are a number of means by which the farmer can influence pasture composition.

With the exception of grazing, all of these processes involve recurring costs, so it is important to exert the utmost possible control through the grazing animal.

A Middle Miocene Rhinoceros Quarry In Morrill County, Nebraska (With Notes On Hip Disease In Diceratherium), Robert M. Stecher, C. Bertrand Schultz, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum (1924–2023)

Extensive deposits of fossil rhinoceros bones have been excavated from University of Nebraska State Museum collecting localities Mo-113, -114, -115, -116, and -118 some 8 1/2 to 9 1/2 miles north of Bridgeport, Morrill County, Nebraska. The fossils were associated with other faunal elements in the lower portion of the Marsland formation (middle Miocene) of the Hemingford group. The rhinoceros is considered to be Diceratherium niobrarensis Peterson, geologic variety. A pathologic right femur of D. niobrarensis provides evidence of hip disease in the medial Miocene rhinoceroses.

Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.

Bulletin of the University of Nebraska State Museum (1924–2023)

Ten species of Recent mammals that formerly occurred in Nebraska have been extirpated there by European man. Surprisingly few specimens of the species concerned are preserved in museum collections. Perusal of a representative segment of the historical literature pertaining to Nebraska has revealed records of occurrence of most of the extirpated species that provide a basis for estimating the former distribution of each in the State.

Bird Problems And Control In Western Australia, John L. Long

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

ALTHOUGH wild birds are mostly beneficial in Western Australia, there are certain species which are damaging to agriculture and the home gardener.

Food For Thought In Rabbit Poisoning, J W. Leighton

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

SINCE the introduction of the "1080" Poisoning Unit Scheme in 1955 by the Agriculture Protection Board reasonable control of rabbit numbers has been obtained.

Besides this many important side effects have resulted.

Introducing Aquatic Ecology To Ninth Graders, Inez P. Sutton

Masters Theses

Chapter I

Introduction

In discussing the basis for teaching high school biology, Van Deventer¹ states, "...the present typical course in high school biology serves adequately neither the terminal student nor the college entrance student." He holds that today's courses present watered-down versions of college courses to the student before the intelligence of the student has matured enough to grasp such subject matter. As a result there is very little carry-over value from such courses, and the students may even develop a dislike for biology. This study constitutes an effort to understand these problems and to devise ways of solving …

The House Fly (Musca Domestica), Clee Francis Howard Jenkins

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

MANY insects are so commonly associated with man and his dwellings that they may almost be called domesticated.

In olden days the presence of these insects was accepted as a matter of course, but present knowledge shows that many of them can be important disease carriers while others may cause damage to food and clothing.

Dwarf Fruit Trees, Frank Melville

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

IN this country where most fruits and particularly apples and pears are grown without irrigation, heavy crops and summer stress restrict tree size.

The aim of most growers therefore, has been to grow larger trees and little interest has been shown in trees with dwarfing tendencies.

However, in countries with ideal conditions for growth, trees tend to grow too big and become uneconomic in terms of labour costs.

Control Of The Emu, C D. Gooding, J. L. Long

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

Vermin research officers C. D. GOODING and J. L LONG give the latest recommendations for control of the emu, based on a series of observations and poisoning experiments in the northern wheatbelt.

Vermin Symposium Report : Wanted : A New Approach To Rabbit Control, A R. Tomlinson

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

THE main reason why rabbits have not increased as rapidly as their amazing capabilities might have led people to expect has been a series of years not suitable for full breeding.

This has been more important than myxomatosis and "1080". This was one of the thoughts taken away by those who attended the rabbit control symposium held in Perth recently.

Studies In Experimental Evolution, William Sidney Boyle

Faculty Honor Lectures

The Principle of organic evolution is the most fundamental one yet discovered in the sciences concerned with the nature and origin of living things. During the one hundred years which have elapsed since Darwin's explanation of the mechanisms of evolution a great deal has been learned to supplement his theory. Nevertheless, students of evolution universally acknowledge the significance of his profound contributions. The importance of natural selection as a creative force in evolution is inescapable.

The present discussion is chiefly concerned with techniques which the writer has used to accelerate, or at least to manipulate, the evolutionary processes. It may …

Preliminary Report: Monolayer Behavior Studies, 1959, Bureau Of Reclamation

Publications (WR)

During the fall of 1959, monolayer behavior studies were made on two lakes in the southwest; Boulder Basin of Lake Mead, Nevada, and Lake Sahuaro near Phoenix, Arizona. These studies were made to evaluate the effect of geographical and climatological conditions on movement and behavior of monolayers. The Lake Sahuaro tests also were used to provide data for design and development of improved methods of application and maintenance of a film on this lake in anticipation of full scale, evaporation-reduction tests to be performed there during the summer of I960. The Lake Mead studies produced the following general points of …

Wild Dog Control In The North-West, R J. Fraser

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

BECAUSE of its sparsely-settled condition, the North-West of Western Australia is almost an ideal breeding-ground and hunting-ground for wild dogs.

Even the best of the pastoral country is but thinly populated and there are large areas of rugged country which is seldom traversed by white men.

Rabbit Control In 1960, C Marshall

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

IN the year 1859, an enthusiastic sportsman in Victoria took delivery from the clipper "Lightning" of a small consignment of wild European rabbits which he joyfully released on his estate at Barwon Park, near Geelong, in order to assure himself of some rough shooting.

He was not the only rabbit importer on record—tame rabbits were brought into Australia before and after 1895 and doubtless there were other importations of the wild rabbit—but he is generally credited—or discredited—with having triggered off the rabbit plague.

A Successful Campaign Against The Euro, E H M Ealey, T. M. Richardson

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

RESULTS from a five-year research programme carried out by the C.S.I.R.O. on the Abydos-Woodstock Pastoral Research Station indicated that euros could be controlled in a practical and economic way by the traditional method of water poisoning,

if it was continued for an extended period and carried out over a large area. Smallscale trials supported this claim, but no opportunity had occurred to assess the practicability of a large-scale poisoning operation.

Termites Or White Ants, Clee Francis Howard Jenkins

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

TERMITES are commonly but erroneously called "white ants."

Actually they are more nearly related to cockroaches than to ants, but their general appearance and subterranean habits have given strong support to the popular designation.

They may be divided into two major groups from an economic point of view, viz., wood-dwelling and earth-dwelling termites.

The Romney Marsh, J A. Mallett

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

THE Romney Marsh, sometimes known as the Kent, is the most popular of the British longwoel sheep breeds used in Western Australia.

Rams of this breed are widely used for mating with Merino ewes, the crossbred female progeny of the matings being in demand for subsequent mating with Downs-type rams to produce export Iambs.

Malaysian Parasites Xxxv-Xlix, W. W. Macdonald

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This is the third Study of the series from this Institute on the external and internal parasites and the biting insects of the Malaysian region. The earlier two volumes were planned and edited by Dr. J.R. Audy, and on his departure from Malaya in the middle of 1959 Mr. W. W. Macdonald continued the work which had been begun and collated and edited the papers in this present Study.

In the two previous volumes (Study No. 26, 1954 and No. 28, 1957) the emphasis was on the taxonomy of Trombiculid mites. In the present volume the emphasis has changed, and …

Notes On Scottsbluff, Nebraska, Tornadoes, 27 June 1955, Robert G. Beebe

National Oceanographic and Atmospheric Administration: Technical Reports and Related Materials

Some general characteristics of thirteen tornadoes that occurred on the afternoon of June 27, 1955 in Scottsbluff County, Nebraska, are related. Two of these caused widespread attention due to their size and their proximity to the cities of Scottsbluff and Mitchell, Nebraska. These two were photographed extensively by residents near their paths. The experience of two men directly beneath one of the two large tornadoes is related.
