A Conceptual Draft Of A Dynamic Hydro-Biological Model For Lake Mead, L. G. Everett, Bureau Of Reclamation

Publications (WR)

Food and energy transformation in an aquatic system must be understood in order to develop a simulation approach. This report provides a comprehensive study of an aquatic ecosystem. The objectives of this report are to show: (1) the biological relationships in an aquatic system (2) the role of nutrients in the biological cycle (3) the role of abiotic factors in a limnetic environment (4) the status of the art of "Eutrophication modeling".

Don't Crop Areas Liable To Waterlogging, Department Of Agriculture, Western Australia

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

The increasing areas of crops being sown in high rainfall districts make it likely that many crcp areas include sections liable to severe waterlogging.

This report presents results of a 1970 trial which clearly show that sowing such sections is not economic.

Grain Sorghum In The Ord Valley : Three Crops A Year?, P J. May

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

High temperatures and ample irrigation water allow grain sorghum to be grown throughout the year on the Ord River Irrigation Area, and observations in 1969-70 indicated that it may be possible in this area to produce three crops in one year from one planting, by ratoon cropping.

This article describes the technique and discusses its possibilities on the Ord.

The sorghum midge, one of the worst pests of sorghum, could well make ratoon cropping impossible, but the midge has not yet been seen in this area.

Elementary Human Genetics, A Help To Teachers, Elizabeth W. Reed

Journal of the Minnesota Academy of Science

ABSTRACT - Two pilot courses in human genetics, which were sponsored by the Minnesota Human Genetics League, are described. One was given in Minneapolis and one in Osseo, Minn. Each course consisted of ten two-hour class sessions, carried professional credits and was geared to the level of elementary and high school teachers, principals and special education personnel who made up the class membership.

Impoundment Effects On Water Quality As Reflected In Parasitism Of Reservoir Basses, David A. Becker

Arkansas Water Resources Center Technical Reports

Our aquatic environments are rapidly becoming useless as natural resources through pollution from various sources. It is therefore necessary for us to further understand the various means which relate to this process. The interrelationships between the physico-chemical and biological water qualities undergo marked changes during the ageing of a reservoir. Eutrophication of these impoundments render them rela-tively useless as natural resources. It thus becomes apparent that we must gain further knowledge of these processes if we are to devise methods for proper reservoir management.

Fisheries Report No 9 - The Fauna And Flora Of Monte Bello Islands, A. A. Burbidge Dr

Fisheries Research Reports

Two visits were made to the Monte Bello Islands in 1970 and 1971.

The aim of the visits was to examine the islands for the presence of native mammals and other fauna, and to explore the possibility of re-establishing fauna now extinct,

The first survey was carried out in conjunction with a more detailed examination of the Dampier Archipelago. The fisheries patrols vessel "Dampier" was used to reach the islands and as a base. Personnel were R. Johnstone (W.A. Museum), E.J. Little and J.D. Harman (crew of the "Dampier"), R.F. Dear and A.A, Burbidge, all from the Department of Fisheries …

Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr

Fisheries Research Reports

Millstream has long been recognised as an unique and outstanding area, both scenically and from a biological aspect. The area of prime interest consists of a series of deep pools in the bed of the Fortescue River (about 15 miles long including Gregory Gorge) and the springs and streams which feed them. Most of the springs are in the sides of the river bed but one of the largest is about 1% miles to the south. This feeds a swift flowing stream running north into the river bed.

The first Europeans to see the area were the exploring party led …

Blockade Of Acetylcholine Receptors By Cobra Toxin Electrophysiology And Pharmacology, Henry A. Lester

Student Theses and Dissertations

Cholinergic transmission has been studied in the presence of a pure polypeptide toxin, of known amino-acid sequence, from cobra venom. For the frog sartorius myoneural junction, micropipette electrodes and on-line computer were used to show that the toxin specifically and irreversibly inactivates postsynaptic acetylcholine (ACh) receptors. Raja and Torpedo electroplaques also show nicotinic pharmacology and were similarly affected by the toxin. The toxin failed to affect the muscarinic receptors of the isolated frog heart or the receptors of Aplysia neurons (neither nicotinic nor muscarinic). These and other observations suggest that the toxin's pharmacological specificity is confined to nicotinic ACh receptors. …

Tree Establishment In The Wheatbelt, F Batini

Although most of the Forests Department's activity has centred around the State Forests in the higher rainfall areas, the Department has, for many years, encouraged the planting and conservation of trees throughout the farming areas.

Growing Plants With Salty Water, C V. Malcolm, S. T. Smith

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

LACK of good quality water in many parts of Western Australia often forces people to use salty water for irrigation and gardening.

This article gives some hints on how to reduce salt damage to plants when salty water must be used for irrigation or gardening.

It includes a table of plants which may be irrigated with water of varying degrees of salinity and lists precautions which should be taken for each group.

New Varieties Could Extend The Peach Canning Season, S R J Newton

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

THE peach canning industry in Western Australia at present has only a limited period of operation, coinciding with the harvest time of the major variety, Golden Queen.

New canning peach varieties tested at Stoneville Research Station could be used to extend the harvest period of canning peaches beyond that of the present standard variety, Golden Queen.

This would have obvious advantages for growers and a canning industry.

The South African variety Keimoes was the most promising canning peach tested. Tests on other varieties are continuing.

Trickle Irrigation, B Swan

THE introduction of trickle irrigation has caused tremendous interest among commercial irrigators. While not a new concept, its application was formerly restricted to glasshouse and nursery use.

Where sprinklers are used wind can result in uneven irrigation, reduced yields and spoilt produce.

Net Rainfall In A Multi-Storied Aspen Forest Community, J.R. Clements

Aspen Bibliography

This paper presents mathematical equations describing the relationships between the amount of net rain per storm under each crown canopy and the amount of gross rain per storm in a multi-storied forest community. The relationships were curvilinear and accounted for gradual filling of the storage capacity of the vegetation. The rate of increase of net rainfall was successively less for each crown canopy in turn starting with the uppermost canopy in the forest. The equation coefficients varied in respect of the position of the crown canopies in the vegetal profile and also in respect of variations in vegetal structure within …
