Tree Lucerne : A Fodder Crop With A Future, Laurence C. Snook

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

IN December, 1952, an article was published in this Journal drawing attention to the potential value of white flowered tree lucerne (Cytisus prolifer) as a source of nutritious green fodder during the dry summer months.

Figures were quoted to show that heavy yields could be obtained year after year with very little effort, and no outlay other than for fertiliser.

The advantages to be gained from the cultivation of this tree were made very apparent and many farmers set out to grow the shrub.

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.

Vibrionic Dysentery Of Pigs, M R. Gardiner

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

VIBRIONIC DYSENTERY of pigs, also known as porcine vibriosis and swine dysentery, has been recognised for many years in the U.S.A. It was first reported in Australia in 1938, in South Australia, and later in both Victoria and New South Wales.

This brief description of a disease recently diagnosed for the first time in Western Australia is given so that breeders have some chance of recognising it in their herds. Suspected cases should be reported without delay.

Antibiotic Residues In Milk : The Farmer's Responsibility, N Ingleton

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

THE LEVEL of antibiotic residues in commercial milk supplies has been steadily increasing over the past few years.

These residues find their way into the bulk milk as a result of milk from cows under antibiotic treatment for mastitis or other infections being included in the bulk milk for sale.

Stocking Rate And Pasture Management, B F. Carlin

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

FARMERS west of the Great Southern Railway, raising sheep and beef cattle, frequently associate soil deficiencies with difficulties in holding sub. clover in their pastures.

Field observations and some trials in those districts indicate that in many paddocks the problem arises through undergrazing rather than a deficiency in the soil.

Evolutionary Relationships Among The North American Mallards, Paul A. Johnsgard

Papers in Ornithology

A comparative morphological, behavioral, and electrophoretic study was undertaken on six populations of North American mallards that are currently considered by the A.O.U. Check-list to comprise four species and two additional subspecies. These include Anas p. platyrhynchos, A. d. diaxi, A. d. novimexicana, A. f. fulvigula, A. f. maculosa, and A. rubripes. These forms are essentially allopatric in their breeding distributions, with the major exception of A. p. platyrhynchos and A. rubripes, which overlap throughout a several-hundred-mile zone in east-central United States.

Geographic ranges and population sizes are estimated, and evidence is presented to indicate that the …

Mortality Of Eastern Brook Trout Caused By Plerocercoids (Cestoda: Pseudophyllidea: Diphyllobothriidae) In The Heart And Viscera, Glenn L. Hoffman, C. E. Dunbar

United States Fish and Wildlife Service: Publications

It is well known that migrating helminth larvae do a great amount of damage to the host. Often, however, the host is relatively large and the damage done by few larvae is not serious. When the host is very small the mechanical damage, at least, must be proportionately greater for each larva present. An unusual case of mortality of small brook trout (Salvelinus fontinalis) roughly 2 to 4 inches long was brought to our attention. Examination of the mortalities, as well as survivors, revealed relatively large diphyllobothrid larvae (fig. 1) in the chambers of the heart, liver, pericardial …

Notes On Sanguinicola Davisi (Trematoda: Sanguinicolidae) In The Gills Of Trout, H. S. Davis, Glenn L. Hoffman, E. W. Surber

United States Fish and Wildlife Service: Publications

In 1953 the late Dr. Davis recorded the presence of an unnamed trematode from the gill blood vessels of fingerling cutthroat trout (Salmo clarki) and fingerling steelhead trout (Salmo gairdneri) at the Alsea Hatchery and in yearling rainbow trout (Salmo gairdneri) at the Oakridge Hatchery, both of the Oregon State Game Commission. Subsequently, two blood flukes, Sanguinicola davisi and S. klamathensis, were described from trout by Wales (1958). The present species was determined to be S. davisi by one of us (GLH). This report supplements data reported by Davis (1953) and Wales (1958). …

Studies On Controlling Oyster Drills In Tomales Bay, Clarence Irwin Haydock

University of the Pacific Theses and Dissertations

The primary purpose of this study was to evaluate the feasibility of controlling oyster drills in Tomales Bay, particularly Urosalpinx cinerea and Ocenebra Japonica (astropods, Muricidae), with chemicals which have been succesfully tested on a number of oyster pests, Including urosalpinx, in Long Island Sound (Loosanoff , 1956- 1961). The problem was polo to provide information. en the present status of drills alle is the bay, a basic preliminary in evaluating others of pest control.

The Biology Of Karyolysus Dilloni N. Sp. From Rana Aurora Draytoni, Wayne Aldo Sorsoli

University of the Pacific Theses and Dissertations

While investigating various Amphibia of Central California for blood inhabiting parasites, the writer found a parasite in the blood of the Rod-legged Frog (Rana aurora draytoni) which exhibited the characteristics of Karyolysus, yet was different from any described; this same parasite had been previously observed by Dr. D. L. Lerhmann, Associate Professor of Zoology, University of the Pacific. In order to increase the knowledge of this form, further investigations were undertaken.

The first step was to determine the life cycle in the vertebrate host and, if possible, to find the invertebrate host and to elaborate the developmental stages in the …

Dissertations and Theses @ UNI

Pair-Formation Mechanisms In Anas (Anatidae) And Related Genera, Paul A. Johnsgard

Paul Johnsgard Collection

Although the" courtship" behaviour of waterfowl has attracted widespread interest and has been the subject of several major papers (e.g. Heinroth 1911, Lorenz 1951-1953), the actual means by which pairs are formed in most species of waterfowl remains unknown. We may conclude by inference that the females of most species of ducks must actively "select" their mates, for the elaborate male displays and plumage patterns present in the group can only be reconciled in terms of sexual selection. In addition, any observer of waterfowl will soon realize that it is the males which actively " court" the females, and that …
