Modifying Fertiliser Practices, J S. Yeates, D. M. Deeley, M. F. Clarke, D. Allen

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

If modified fertiliser practices are adopted phosphorus losses from the Peel-Harvey catchment can be reduced. Farmers can save money on fertiliser applications and the need for more expensive catchment management measures to reduce algal pollution of the estuary will be avoided.

Research data available so far indicate that, with farmer co-operation and the use of the new slow release fertiliser New Coastal Superphosphate, long-term phosphorus application rates can be reduced by 30-40 per cent - and possibly even halved - without lowering agricultural production. This will also reduce phosphorus loss to drainage water.

Although much of the research since 1982 …

Great Plains Wildlife Damage Control Workshop Proceedings

Most modern environmentalists during their formative years have had little actual contact with wildlife under natural conditions. Their wildlife philosophies have been developed via the mass media and from experiences with animals as pets or confined in zoos. In general, modern environmentalists are sincere, dedicated, idealistic and enthusiastic, but they often lack realism and are blessed with the innocence of naivete. The majority of people in the United States now exhibit strong affection for wild animals and are deeply concerned over any actions perceived as causing pain to individual animals. These attitudes towards wild animals will impact on future wildlife …

The Wildlife Society's Committee On Wildlife Damage Control, Terrell P. Salmon

Great Plains Wildlife Damage Control Workshop Proceedings

In 1982, the President of the Wildlife Society created a Committee to make recommendations on what the Society should do to be an attractive organization for wildlife professionals specializing in wildlife damage control. The Committee, composed of 7 professionals in wildlife damage control, made 13 recommendations to the Society. Which, if implemented will improve the Society's relationship with wildlife damage control professionals.

Rhode Island's Barrier Beaches: As Assessment Of Their Future, David J. Hampshire

Marine Affairs Theses and Major Papers

The lands and waters of the coastal zone have either been mismanaged or not managed at all since the early settling of the United States. Nowhere is this more evident, perhaps than along the nation's barrier beaches. Rhode Island, while not suffering nearly from the degree of development on its barrier beaches as other states, is no exception. Economic pressures brought to bear have forced federal, state, and local governments to grapple extensively with this issue. The need for the preservation of barrier beaches in their natural state cannot be overstated and is recognized by all levels of government. This …

Improved Methods And Guidelines For Modeling Stormwater Runoff From Surface Coal Mined Lands, Michael E. Meadows, George E. Blandford

Investigations were conducted to determine appropriate event curve numbers for surface mined disturbed watersheds; and performance of four synthetic unit hydrograph models (SCS curvilinear, SCS single triangle, Williams and TVA double triangle) on 38 USDA experimental watersheds in 14 physiographic provinces using in excess of 270 events. A second test using only the SCS curvilinear unit hydrograph on 11 small watersheds and 48 events was conducted to investigate the excess rainfall pattern simulated with the curve number model. A procedure for developing a unit hydrograph using the time …

A Comparative Study Of Geologic Information Derived From Visually Interpreted Slar And Landsat Imagery, William Leo Barry

All-Inclusive List of Electronic Theses and Dissertations

Geologists have used numerous tYPes of remote sensors for the interpretation of earth surface features. Two of the more recently developed remote sensors are SLAR (side-looking airborne radar) and LANDSAT (ERTS, Earth's Resources Technology Satellite, renamed L~~DSAT). The author undertook a straightforward qualitative research study to ascertain and compare the amount, types and reliability of the geologic information which can be derived separately from visually interpreted LANDSAT and SLAR imagery. The area selected for this study is located in north-central Arizona. The imagery analyzed consists of unenhanced black and white ... multispectral scanner (MSS) bands 5, 6 and 7 LANDSAT …

Survival Analysis For A Red Squirrel Population, Curtis H. Halvorson, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

A 13-year study of an isolated red squirrel (Tamiasciurus hudsonicus) population in Montana has provided the data necessary to analyze their survival. Such long-term, intensive studies of wild populations are rare. When reported, derived (ratio) estimates are used to develop survival information as Gross et al. (1974), and Keith and Windberg (1978) did in respective 9- and 15-year lagomorph studies. A more accurate method, following cohorts, was used by Armitage and Downhower (1974) and Mosby (1969), who presented results for six or more year-classes of sciurids in actuarial tables (Deevey, 1947; Allee et al., 1949).

Artificial Floating Islands: Cities Of The Future, Earl A. Proetzel

Marine Affairs Theses and Major Papers

This report will investigate the feasibility of large-scale artificial floating islands, to solve problems posed by over-population and environment-burdening activities in coastal areas. The investigation will focus on the historic, technical, utilizable and legal aspects of artificial floating islands. Although this report exemplifies artificial floating islands developed for offshore cities, electrical power generation and basing for the military, its content is applicable to any offshore floating development.

Causes Of Localized Copper Corrosion In Drinking Water Supplies, R. A. Sims, R. W. Raible

Arkansas Water Resources Center Technical Reports

Excessive amounts of copper have been observed in drinking water at certain installations on Lake DeGray and at isolated locations in the Arkadelphia area of Arkansas. A study of these installations was conducted to determine the source of the copper contamination. The supply water was very low in copper and therefore dissolution of the copper plumbing caused by low water pH and long residence times was determined to be the most probable source.

Soviet Predatory Practices In The U. S. Liner Trades: Strategy And Prospects, Daniel D. Thompson

Marine Affairs Theses and Major Papers

The impressive growth of the Soviet Merchant Marine during the past two decades. and its anticipated future expansion have given rise to questions concerning the likely future impact of that fleet on world shipping and the relative importance of maritime commerce to the Soviet Union itself. U.S. owners and regulatory bodies have, along with other Western owners and shipping bodies, consistently pointed an accusing finger at the Soviets for attempting to capture more than a fair share of general cargo tonnage in the world liner market. Charges of predatory Soviet rate cutting practices have been widely advertised by American operators …

Acceptability Of Six Candidate Groundcovers To Meadow Voles, Edwin Lewis, Donald H. Rhodes, Milo Richmond

Eastern Pine and Meadow Vole Symposia

Meadow vole food preferences were examined by means of a series Of two day trials where pairs of plants were offered. Of the six plants tested, three (white clover, red clover, alfalfa) were found to be highly preferred by the voles, one (red fuscue) was acceptable, and two species (myrtle and crownvetch) were unacceptable. The results suggest that the undesirable groundcovers may be used as a deterrent to the establishment of meadow vole populations.

Nutrients And Acid In The Rain And Dry Fallout At Fayetteville, Arkansas (1980-1982), George H. Wagner, Kenneth F. Steele

Arkansas Water Resources Center Technical Reports

Wet and dry fallout at Fayetteville, Arkansas have been collected separately and analyzed since April, 1980. The precipitation-weighted-average pH for two yearly periods of rainfall were 4.72 (6/80-5/81) and 4.75 (6/81-5/82). This corresponds to a concentration of the acid ion, H+, of about 18 parts per billion (ppb). Pure water in equilibrium with the CO2 of the air would have a pH of 5.65 (2.2 ppb of H+). The range of pH during this two year period was 3.86-7.74(140-0 ppb H+) for the rainfall. Aqueous extracts of the dry fallout were always in the 6.75-7.87 pH range, i.e., neutral to …

Monitoring Of Groundwater Levels For Real-Time Conjunctive Water Management, Richard C. Peralta, Vince Mazure, Paul Dutram

Arkansas Water Resources Center Technical Reports

Water users in the Arkansas Grand Prairie wish to maintain sufficient groundwater levels to: insure adequate groundwater reserves for time of drought, protect themselves from litigation caused by wells going dry, and insure a sustained yield. Achievement of these goals requires regular measurement of groundwater levels. Review of monitoring practice and technology indicates that spring and fall measurements taken over the entire area using steel tape and acoustic device is preferred for most long range planning. Continuous monitoring is indicated for critical parts of the region where saturated thicknesses are small. Desirable attributes of a data collection/transmission system for such …

Spatial And Temporal Variations In Long-Term Normal Percent Possible Solar Radiation Levels In The United States, Robert C. Balling, Randall S. Cerveny

School of Natural Resources: Faculty Publications

The purpose of this study was to analyze the time and space variations in long-term monthly-averaged daily percent possible solar radiation levels in the United States. Both principal components analysis and harmonic analysis were used to identify the influences of various synoptic-scale climatological phenomena on solar radiation receipt. Generally, an annual cycle was found with maximum percent possible radiation levels occurring in July. In many regions the temporal variance structure deviated from this general annual cycle. The results, which are useful in both theoretical and practical studies, lead to a better understanding of the climatology of solar radiation in the …

Land Use For Timber And Recreation: A Case Study In Victoria, Australia, Lawrence C. Merriam

Journal of the Minnesota Academy of Science

For many years the United States has had major problems in public land use for timber and recreation. Problems in Minnesota's Boundary Waters Canoe Area are an example. Australia is a country with Simi !tar concerns. The State Forests of Central Victoria, administered by the Forests Commission, were heavily burned m 1939. They now have regenerated to commercially mature stands, particularly of mountain ash (Eucalyptus regnans F. Muell.). Within 100 kilometers of the 3 million people in Melbourne, the forests are popular recreation sites. This paper reports on a study made for the Forests Commission aimed at the effective integration …

Hydrological Studies In Soil Salinity, C J. Henschke

Resource management technical reports

Investigations involved examination of near-surface indurated layers to investigate their role in saltland formation. It was found that groundwater could move readily through this layer due to the presence of macro-pores. Close examination of apparently impermeable pallid zone clays, shows that decayed tree roots and large diameter voids provide a continuous pathway for the veritical transport of saline water from deeper aquifers.

Abundance And Biomass Of The Meiobenthos In Nearshore Lake Michigan With Comparisons To The Macrobenthos, Thomas F. Nalepa, Michael A. Quigley

United States Department of Commerce: Staff Publications

The meiobenthos of nearshore southeastern Lake Michigan was quantified by taking cores from three depths (11, 17, and 23 m) at monthly intervals from May to November 1976-79. Total meiobenthic abundance rangedfrom 69,700/m² to 1,300,000/m² and total biomass rangedfrom 0.03 to 0.87 g/m². Nematodes accounted for 80% of all individuals and 66% of the biomass. Most of the major groups peaked in late spring/summer, but some peaked in early spring and fall. With the exception of nematodes, mean annual densities varied from two-fold to twelve-fold at a given station. Harpacticoids, tardigrades, and ostracods tended to be …

The Effects Of Limited Food Availability On The Striped Bass Fishery In Lake Mead, John R. Baker, Larry J. Paulson

Publications (WR)

The original range of striped bass (Morone saxatilis) was along the Atlantic Coast. They were introduced into the lower Sacramento River in 1879 and are now also found along the Pacific Coast. A landlocked striped bass fishery was established in Santee-Cooper Reservoir, South Carolina, in 1954, and they have since been introduced into numerous other reservoirs, including Lake Havasu, Lake Mead and Lake Powell on the Colorado River. Striped bass were introduced into Lake Mead in 1969 in response to declines in the largemouth bass (Micropterus salmoides) fishery that occurred during the 1960s and in order to further utilize the …
