Laser Levelling Land For Flood Irrigation, M D. Green, J. P. Middlemas
Laser Levelling Land For Flood Irrigation, M D. Green, J. P. Middlemas
Journal of the Department of Agriculture, Western Australia, Series 4
Since the introduction of laser levelling to Western Australia's South-West irrigation area five years ago, many farmers have benefited from this new and precise method of land-forming.
The use of lasser controlled earthmoving equipment to redevelop irrigated paddocks has led to improved irrigation efficiency and drainage. Less water is used for each irrigation, water is applied more evenly and less labour is needed. many older, grass-dominated paddocks have been reseeded to improve pasture species.
Eradicating Fruit Fly From Carnarvon, Kingsley Thomas Fisher
Eradicating Fruit Fly From Carnarvon, Kingsley Thomas Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
Late last year the Mediteranean fruit fly (Ceratitis capitata Weidemann) was eradicated from Canarvon, Western Australia by using an intergrated programme of sterile insect releases and bait spraying.
The eradication marked the end of a four-year study on the use and effectiveness of the Sterile Insect Technique, a biological control technique which uses an insect pest against itself. such a study can be used as a basis for treating other threatening insect pests, such as the serious cattle pest screw-worm fly, should they be found in Asustralia.
Being a biological control method, the Sterile Insect Technique is an exellent …
Water Quality For Irrigation, P R. George
Water Quality For Irrigation, P R. George
Journal of the Department of Agriculture, Western Australia, Series 4
Although irrigation and salinity problems are frequently inseperable, there is a range of management methods that can be used to handle marginal quality water. Freuently these methods are simple, but require careful planning.
The wide range in tolerance of crops to salinity can be exploiter to ensure that appropriate crops are selected for the water available.
Because crops vary in their sensitivity to salt uptake in the leaves or the roots, watering methods can be changed to avoid problems. For profitable production enough water should be applied to ensure adequate water is available for plant growth as well as to …
Residual Values Of Australian Rock Phosphates, Michael D A Bolland
Residual Values Of Australian Rock Phosphates, Michael D A Bolland
Journal of the Department of Agriculture, Western Australia, Series 4
For years superphosphate has been the cheapest, convenient and most effective way of supplying phosphorus to newly cleared soils in Western Australia's South-West that are acutely deficient in phosphorus. However its effectiveness as a phosphorus source falls markedly after application. Regular applications are needed to maintaine profitable pastures and crops on these soils.
After a big jump in supperphosphate prices in the mid 970s, researchers tested the use of Australian rock phosphates as potentially cheaper alternative phosphorus fertilisers to superphosphate. On the none-leaching sands, as this article shows, none of the rock phosphates was as effective for plant growth as …
The Imbalance Between Experiment And Theory In Biology: The Need For Theory-Directed Modeling, M. L. Fidelman, D. C. Mikulecky
The Imbalance Between Experiment And Theory In Biology: The Need For Theory-Directed Modeling, M. L. Fidelman, D. C. Mikulecky
Experimentation Collection
In biological and biomedical research, the vast majority of resources are focused on conducting experiments. Most of these experiments utilize animals. Only a tiny amount of resources is spent on theory and modeling. It is our contention and the basic theme of this paper that the imbalance between theory and experiment in biology produces very poor science. The implications of which are that many of the experiments conducted have little real scientific meaning or value and, therefore, go hand-in-hand with unnecessary animal use and suffering. Given the finite resources available for research, the redirection of significant resources from an almost …

The Green Movement: Implications For Animals, Ronnie Z. Hawkins
Environment Collection
The Green movement, a newly emerging political movement that is both global in scope and firmly anchored to each local region at the grassroots level, is destined to be of great import to those concerned with the status of nonhuman animals in our society. Closely allied with deep ecology and bioregionalism, Green thinking embodies an alteration in our perception of the human organism: no longer seen as separate from and superior to all the other components of the ecosystem, our species is placed in context as one among many interdependent forms of life, with the attainment of a sustainable balance …

Aliso: A Journal of Systematic and Floristic Botany
The production of taxonomic monographs is discussed in light of the modern tools that are available for their preparation. There is a great need for more monographs since much of the world's flora is not treated in contemporary revisions. These should be a balance between the traditional aspects that must still be employed such as the nomenclatural framework and the consultation of type specimens, and the use of modem techniques, computer data analysis and field work. The importance of field studies in association with monographic studies is stressed both to give a better understanding of traditional morphological features and to …

The Quaternary Bone Caves And Associated Sites At Wallingford, Jamaica, Donald A. Mcfarlane, R. E. Gledhill
WM Keck Science Faculty Papers
A group of caves associated with the sink of the One Eye River in St. Elizabeth Parish, Jamaica, have been the subject of numerous important palaeontological investigations beginning 1919. Unfortunately, considerable confusion has arisen in the literature through inadequate documentation of different sites. The caves of the immediate area are described and located, and their palaeontological significance is summarised in the light of recent taxonomic review and relevant geochronological evidence.

The Effect Of Dispersed Oil On The Calcification Rate Of The Reef-Building Coral Diploria Strigosa, Richard E. Dodge, A. H. Knap, Sheila C. Wyers, H. R. Frith, T. D. Sleeter, S. R. Smith
Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures
Hermatypic corals represent environmentally and economically important components of the reef ecosystem. Oil spills and clean-up operations in reef areas are potential sources of pollution impact. This paper presents an evaluation of the calcification rate of specimens of the reef-building coral Diploria strigosa in response to 24 hour treatments of chemically dispersed oil at concentrations of 20 ppm. The concentrations and durations were chosen to represent a scenario of a short-term oil spill treated with dispersant passing over a coral reef.
Calcification rates were determined by the buoyant weight technique at several day intervals for up to 29 days following …

Fisheries Report No 68 - The Commercial Fishery For Barramundi (Lates Calcarifer) In Western Australia, Dr N. Morrissy
Fisheries Research Reports
Commercial catch and effort data from the Western Australian fishery for barramundi, Lates calcarifer, over eight years to 1982-83 were analysed. Major stocks and areas of this fishery are Cambridge Gulf (Ord River, port of Wyndham), Kimberley coast, King Sound and Broome coast (Fitzroy River, ports of Derby and Broome), and Pilbara coast (ports of Port Hedland, Roebourne and Onslow) where the Ashburton River is the southern limit to the distribution of barramundi on the west coast. As elsewhere, barramundi stocks are associated with river systems. The Low annual catch of about 30 tonnes appears to be due to the …

Maximizing Expected Profits In Competitive Bidding, Steven H. Bullard
Maximizing Expected Profits In Competitive Bidding, Steven H. Bullard
Faculty Publications
Forest products firms often buy much of their raw material through competitive bidding. The bidding process is vital to such companies, yet models are often used which merely help predict winning bids. Managers should consider expected returns from potential timber buying contracts-the product of profit and the prob· ability of realizing that profit. A general approach is summarized for maximizing expected profit in competitive bidding. For timber buying, profits are net returns minus stumpage costs. The probability of obtaining the profit is the probability a given bid will be accepted, and can be represented by a probability density function. The …

Experimental Summaries - Plant Research
Herbicides affect not only the weeds present in a crop, but also the crop itself. In the absence of weeds, both positive and negative responses to herbicides have been reported in the literature. The negative responses are the most important, especially if yield is decreased below the economic threshold for herbicide use. Factors which are important in determining the level of crop response to a herbicide include the crop species and variety, the timing of the herbicide, the rate of herbicide and the environmental conditions under which the crop is growing.
