Ecological Study Of The Effects Of Strip Mining On The Microbiology Of Streams, Ralph H. Weaver, Harry D. Nash
Ecological Study Of The Effects Of Strip Mining On The Microbiology Of Streams, Ralph H. Weaver, Harry D. Nash
KWRRI Research Reports
The microflora of Cane Branch of Beaver Creek in McCreary County, Kentucky, which drains an area that was strip-mined between 1955 and 1959, was studied and compared with that of Helton Branch which drains a comparable area where there has been no mining. Differences include: the establishment of Ferrcbacillus ferrooxidans, for which procedures were developed for direct colony isolation from the stream; fewer saprophytic bacteria; more numerous and more diversified filamentous and unicellular fungi; and characteristic differences in algal flora. Representatives of 42 genera of filamentous fungi were identified. Of these, 21 were isolated only from Cane Branch. Representatives of …

Bulletin No 3547 - Kimberley Research Station - Progress Report 1968, Western Australian Department Of Agriculture
Bulletins - 3000 - 3999
Rivers flowing to the Gulf of Carpentaria and the Timor Sea have been estimated by hydrologists to carry about three times the water transported annually over the Murray drainage system and the South Eastern slopes which, together, comprise the highly settled agricultural areas of South Eastern Australia.
In 1945, the North Australian Development Committee recommended research in the Ord-Victoria rivers region as a first step toward ultimate agricultural development of this Northern potential and, in 1946, the Kim- berley Research Station commenced operations under the joint control of the Commonwealth Scientific and Industrial Research Organization and the Western Australian Department …

Private Irrigation Systems : Do They Pay?, G D. Oliver
Journal of the Department of Agriculture, Western Australia, Series 4
WESTERN AUSTRALIA, with 71,000 acres under irrigation, can hardly claim to have an important irrigation farming industry.
However, irrigation is daily growing in importance, especially through private schemes. These account for almost half the present irrigated area.

Water Blooms, T E H Aplin
Water Blooms, T E H Aplin
Journal of the Department of Agriculture, Western Australia, Series 4
WHEN a body of water becomes discoloured with a super-abundance of free-floating, microscopic plant or, in rare cases, animal life, it is said to develop a "water bloom."
This article discusses some aspects of the appearance of water blooms, particularly those caused by algae, and with the effects that certain toxic algae have on livestock.

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 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 …

Piggery Septic System, N E. Macintyre
Journal of the Department of Agriculture, Western Australia, Series 4
ONE of the problems of intensive houses for pigs is the disposal of the dung and urine.
If proper arrangements are not made to remove this, it soon accumulates in an offensive pile at one end of the piggery, making an excellent breeding ground for flies.

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

Water Chemistry Survey Of Boulder Basin, Lake Mead, P. R. Tramutt, Bureau Of Reclamation
Publications (WR)
The survey results indicate that the impoundment of water behind Hoover Dam has not adversely affected the dissolved oxygen (DO) content and that water quality and DO content were uniform regardless of depth. The study made in April-May 1964 will provide water quality data of Lake Mead prior to releases from Lake Powell as a basis for evaluating Lake Powell's effect on water quality and limnology of Lake Mead. The performance of a DO analyzer was tested and found unsatisfactory at depths below 150 ft. Parameters tested by standard chemical analyses of water samples in the Denver Laboratory and by …
Amphibians And Reptiles Of Vigo County, Indiana, David Rubin
Amphibians And Reptiles Of Vigo County, Indiana, David Rubin
All-Inclusive List of Electronic Theses and Dissertations
Vigo County, Indiana is an extremely interesting area for herpetological studyo Its geographical location allows for the interplay of faunal elements from east, west, north, and south (Smith and minton, 1957) and its physiography permits investigation of the relations of terrain and glacial geology to herpetofaunal distribution. Blatchley (1891, 1899) published two papers on the amphibians and reptiles of the county and Allyn and Shockley (1938) reported on the county's salamandersa The present paper has the following objectives: to determine which species occur or have recently occurred in Vigo County; to determine amphibian and reptile distribution in the county; to …

Fruit Growing In Western Australia, Western Australian Department Of Agriculture, Western Australian Tourist Development Authority
Fruit Growing In Western Australia, Western Australian Department Of Agriculture, Western Australian Tourist Development Authority
Horticulture published reports
Revised 1965.
The Mediterranean type climate of the coastal belt of the south-west of Western Australia is suitable for the commercial production of apples, pears, various stone fruits, oranges, grapes, and several other less important fruits. The warm dry summers (November-March), are too severe for the profitable production of many berry fruits and the winters too cool and wet for most tropical fruits. Figs, mulberries and olives all flourish in this climate but, for economic reasons, few are grown commercially.
A small tropical fruit industry, mainly bananas, has been established along the banks of the Gascoyne River at Carnarvon, which …
A History Of The War Service Land Settlement Scheme Western Australia, A, R. Barrett
A History Of The War Service Land Settlement Scheme Western Australia, A, R. Barrett
Farm Systems and Economics published reports
In writing a history of the Western Australian War Service Land Settlement Scheme, it is pertinent to remark that land settlement projects have ever been difficult and, in fact, to date very few have been really successful. However, there has always been the necessity to accede to the desire of returning men to go on the land, also in States such as Western Australia there was and still is the need for further land development. Therefore, when the Commonwealth Government offered to provide the funds for servicemen's rehabilitation on the land the State gladly accepted and agreed to take responsibility …
