Paspalum Vaginatum : For Salty Seepages And Lawns, C V. Malcolm, I. A. F. Laing

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

PASPALUM VAGINATUM, aptly termed "sea shore paspalum" has an amazing ability to thrive in wet salty situations. It is also a good lawn grass.

This article reviews where and how the grass may be used.

Dormancy And Life Span Of Saffron Thistle Seeds, B J. Quinlivan, J. R. Pierce

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

RESEARCH in the Geraldton area has indicated that seeds of the saffron thistle (Carthamus lanatus) spread their germination over some seven years but most germinate in the first two years.

Factors influencing the rate of germination and the survival of seeds are the depth of burial and the presence of termites in the soil.

The Role Of Adventitious Reinforcement In Operant Discrimination, Alan Kamil, John W. Davenport

Avian Cognition Papers

Rats were trained in 2 S^D-S^Δ discrimination experiments in which the effects of an S^D-postponement contingency during S^Δ and temporal regularity of S^Δ duration were assessed. Experiment I showed that discrimination is markedly facilitated by the presence of an S^D-postponement contingency of either fixed or variable duration. Experiment II showed that variable-duration S^Δ periods in a noncontingent schedule can also greatly enhance formation of an operant discrimination. These effects were attributed to differences in the probability of adventitious reinforcement of S^Δ behavior by S^D events.

Individual Sow Feeders, P Mcnamara

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

FOOD is the major cost in any pig enterprise and it is particularly easy for waste to occur in the breeding herd.

Individual feeders enable the pigman to feed each sow according to her need, and enable the sows to eat their feed slowly or quickly as they choose.

Factors Affecting Nesting Success Of The Canvasback In The Aspen Parklands, Jerome H. Stoudt

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The Minnedosa study area is located in the southwestern portion of Manitoba just south of the town of Minnedosa. It is 90 square miles in size and roughly square in shape. The Aspen Parkland, in which the study area is located, is characterized by gently rolling terrain and black soils. Mixed farming is the rule with emphasis on small grain production consisting of wheat, barley, and oats. Roughly 50 percent of the water areas in the parkland are ringed with aspen, Populus tremuloides, and large blocks of aspen are interspersed throughout the area. The Minnedosa area differs because of …

Weaning Lambs Under Pastoral Conditions, H Suijdendorp, L. Parsons

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

IN the summer rainfall region of the pastoral areas lambs are too often born too late to ensure their survival.

In good seasons with a fair measure of winter rain more late lambs will survive, but losses are still serious. The only solution to this problem is to make sure lambs drop in May-June.

But the presence of late and often unmarked lambs at mating time is a disturbing influence, which makes it hard to advance the established mating pattern.

One Shot Baiting, C D. Gooding, L. A. Harrison

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

THE Agriculture Protection Board introduced the first of its contract poisoning schemes in 1955 in the lower South-West when three units undertook the first "1080" poisoning for farmers in Western Australia.

The originators of one-shot baiting describe this new technique and explain how it should be used for best results on the farm.

Attack The Rabbit At Home : Destroy Warrens And Harbourage, J S. Crawford

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

Effective rabbit destruction often calls for a carefully worked out control programme consisting of poisoning, fumigating and warren and harbourage destruction.

Possibly the most effective means of not only controlling rabbits but ultimately eradicating them from holdings is the destruction of warrens and harbourage.

The Fox : Status And Control, C D. Gooding

Dingo Control : Organised Ground Baiting Drives At Mating Time, C D. Gooding, J. J. Freeth

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

DINGOES in Western Australia, like all "creatures of nature", have a well defined seasonal pattern of behaviour.

This is influenced somewhat by weather variations, but even in remote areas where violent fluctuations in rainfall occur from year to year, the dingo still breeds at roughly the same time.

The numbers of pups born and the numbers which survive each year varies a lot, but life goes on at roughly the same tempo under most seasonal conditions.

Effects Of Beaver On Stream Flow And Water Quality, James W. Bates

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water, one of the major resources of the western lands, controls the economy and expansion of the communities. Industry, agriculture, timber, livestock, game and home water needs are all dependent upon a steady and continued flow of water from wells, springs, and rivers. Water is derived from one source, precipitation, which occurs in the form of rain and snow. Watersheds which are properly managed accumulate a substantial snow pack during the winter which is the life-giving source of water for our springs.

The Utah Water and Power Report (1948) indicates the annual precipitation over the entire state of Utah averaged …

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.
