Numerical Computer Perpheral Interactive Device With Manual Controls, James C. Fletcher, Arthur I. Zygielbaum, Stanley S. Brokl

School of Natural Resources: Faculty Publications

A computer peripheral device is disclosed which in cludes a joystick whose displacement from a center position along two axes X and Y in either a plus (+) or a minus (-) direction is sensed. The displacement magnitude in either direction controls the rate of clock pulses provided by a variable frequency clock. The clock pulses from the two clocks are accumulated in two separate counters, whose contents are dis played. The contents of the counters are suppliable to a computer to update the contents of specific cells which define the position of a cursor on a display which is …

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 …

Micronutrients And Biological Patterns In Lake Mead, Hasan K. Qashu, Lorne G. Everett, J. S. Carlson, Bureau Of Reclamation

Publications (WR)

Progressive increases in concentration of dissolved solids in the Colorado River water from Lake Powell to Imperial Dam seem to alter plankton dynamics and biological productivity of the river. Also, changes in biological productivity and micronutrients concentrations occur within the same reservoir. Development of a digital simulation model to predict micronutrients concentrations and biological productivity is necessary for diagnosing changes in plankton population and effluent-carrying capacity of the system. The objectives of the study are: (1) to determine trace metal balance at different locations in Lake Mead, (2) to measure biological productivity and conduct plankton population counts at each sampling …

Some Wildflowers Of Western Australia, C. F. H. Jenkins, A. S. George

Bulletins - 3000 - 3999

MUCH recent discussion on conservation has centred around the importance of wild flower reserves and the need for protecting one of thci State's most important tourist attractions. Although less important to visitors than the flowers, many of our wild animals hold equal interest for nature lovers and scientists, and they also need protection.

ALTHOUGH the brilliance and diversity of West Australian wildflowers are widely appreci­ated, the localities where they can best be observed in their natural state are not so well known.

In this article a brief outline is given of the more important districts in the south western part …

Concentration Of Co, In The Air Above A Sugar Beet Field, K.W. Brown, Norman J. Rosenberg

School of Natural Resources: Faculty Publications

The concentration of CO, in air sampled above a sugar beet crop was measured during July, August, and early September 1966 at Scottsbluff, Nebr. During July the mean daytime concentration decreased from 310 ppm to 283 ppm as the leaf area index increased from 0.8 to 4.0. Only small deviations from the mean daytime Concentration of 283 ppm occurred during the remainder of the season. The mean nocturnal concentration during this period was 320 ppm and was more variable than the daytime concentration. The daily amplitude of concentration averaged 70 ppm and was as great at times as 100 ppm. …

Soil Conservation Handbook, D J. Carder, G W. Spencer, Soil Consevation Service

Books & book chapters

Soil Conservation means, basically sound land management. With good management the Ste's resources of productive land can be bot only maintained but actually improved. It is a question of deciding the best use for each soil type and situation. Profitable Production must be kept up in changing economic conditions without destroying land assets in the process.

Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Ecological studies on the distribution of fairy shrimps have been made from 246 sites in the sandhills region of Nebraska. New records for Nebraska have been established for Artemia salina, Branchinecta campestris, B. lindahli, B. mackini and Cyzicus mexicanus. Seasonal populations of shrimp have been located in habitats containing permanent fish populations. Water mineralization was the dominant environmental condition related to the distribution of phyllopods with sodium and potassium compounds predominating in the strongly alkaline lakes. Several of the Artemia lakes were classified as hydroxide sites. Many of the alkaline ponds, where B. lindahli and B. campestris flourish, are …

Fisheries Report No Iv (6) - Report On The Current Status Of Crocodiles In Western Australia, H. Robert Bustard Dr

Fisheries Research Reports

The aim of the survey was fivefold,

(1) to determine the present abundance and composition of saltwater crocodile populations in Western Australia,

(2) to comment on the status of the freshwater crocodile in Western Australia following 7 years of total protection,

(3) to locate study area(s) for detailed work on crocodile biology,

(4) to investigate the feelings of people on the spot (especially shooters or ex-shooters) towards crocodile conservation, and

(5) to investigate law enforcement problems relating to crocodiles

Fishery Report Iv (4) - Report On The Barramundi Fishery In Western Australia, N M. Morrissy

Fisheries Research Reports

Barramundi are widely distributed in rivers and estuaries in the semi-tropical and tropical regions of the Indo- Pacific from South China to the Persian Gulf and along the coast of northern Australia. The limiting factors to the distribution appear to be temperature and salinity.

Agroclimatic Calendar For Nebraska, R. E. Neild

School of Natural Resources: Faculty Publications

Crops are planted so growth, development and harvest correspond closely to the season most favorable for yield and quality. With exception of fall-seeded small grains and some forages, most Nebraska crops are planted in the spring when temperature and precipitation are increasing.

Development, Verification, And Use Of Methods To Model Chemical And Thermal Processes Lakes Mead And Powell, Bureau Of Reclamation

Publications (WR)

PURPOSE The purpose of the proposed research is to quantify the effects that Lakes Mead and Powell have on the salinity in the Colorado River system, and to evaluate changes that cap be made to the operating system of the reservoirs (within legal/institutional constraints) to enhance salt precipitation and/or minimize evaporation within the reservoirs. The effect of any changes (i.e., selective withdrawal uses, pumped storage, etc.) on reservoir evaporation could also be evaluated with a goal of minimizing evaporation. This will be accomplished through the development of a mathematical model of the reservoirs as described below. BACKGROUND Two major problems …

Fisheries Report No 3 - Western Australian Freshwater Fisheries, Donald D. Francois

Fisheries Research Reports

Most of the Australian States have a comprehensive system of inland waterways, Western Australia, however, is in a less fortunate position. True, the maps of the State show many rivers, but in much of the southern, more populous part, with no summer rain and no winter snow, the majority are virtually a chain of waterholes during the long summer months. At the same time, in a relatively small section in the south-west corner, there is a series of permanent streams flowing through what was originally dense forest. But apart from the three indigenous freshwater crustaceans, the marron (Cherax tenuimanus), the …

Ultrasonic Tracking Of Migratory Fishes With An Internal Tag, Ross M. Horrall, H. F. Henderson, A. D. Hasler

School of Natural Resources: Faculty Publications

First paragraph:

A small ultrasonic tag, 9 mm by 40 mm in size, has been developed by members of the fish orientation group at the University of Wisconsin. The tag emits a continuous signal at approximately 65 kc/sec. The signal is received via a directional hydrophone and a high quality communications receiver. Tracking ranges of up to 1 km have been obtained. The placement of the tag is internal: either into the stomach or into the body cavity of the fish. The tags and tracking equipment have been successfully employed in studies on the open water movements and orientation of …

Fisheries Report No I (1) - The Shark Bay Fishery On Snapper Chrysophrys Unicolor (Quoy And Gaimard), B. K. Bowen

Fisheries Research Reports

As regards both catch and value, the Shark Bay snapper fishery is the second most important scale fishery in Western Australia. Until 195%, the fishing was done solely by means of hard-lines operated from beats drifting over the snapper patches. In 1959 traps were first used with great success and in 196) this method of fishing was again the principal technique.

Prior to the 1960 season there were several suggestions that the use of traps would have a deleterious effect on the fishery. On October 19, 1959, the Western Australian League of the Professional Fishermen's Association wrote to the Fisheries …

Fisheries Report Ii (2) - Preliminary Report On The Effectiveness Of Escape-Gaps In Crayfish-Pots, B. K. Bowen

Fisheries Research Reports

The Western Australian commercial crayfish, Panulinrus cy,nus George, (1962)", is caught in depths ranging from a few feet to approximately 45 fathoms. In the shallow waters large numbers of crayfish measuring, less than the legal minimum length are brought to the surface in the standard commercial crayfish pots. The law requires that these undersize crayfish be returned to the sea, but there is always the temptation to retain them for illegal sale. In addition, the undersize crayfish which are returned to the sea are often damaged by handling. The probability is that their mortality rate is higher than those which …
