Water Conservation Through Irrigation Technology, Donald H. Negri, John J. Hanchar, United States Department Of Agriculture, Economic Research Service Nov 1989

Water Conservation Through Irrigation Technology, Donald H. Negri, John J. Hanchar, United States Department Of Agriculture, Economic Research Service

All U.S. Government Documents (Utah Regional Depository)

Improved irrigation technology and advanced farm management practices offer an opportunity for agriculture to use water more efficiently. Farmers may install new equipment, such as drip irrigation systems, or adopt advanced water management practices to conserve water without sacrificing crop yields. While farmers' decision to adopt water-saving irrigation technology responds to the cost of water, physical properties of the land such as topography or soil properties of the land such as topography or soil texture dominate the choice of irrigation technology.

Herring Gulls, Larus Argentatus, Nesting On Sandusky Bay, Lake Erie, 1989, Richard A. Dolbeer, P.P. Woronecki, T. W. Seamans, B. N. Buckingham, E. C. Cleary

United States Department of Agriculture Wildlife Services: Staff Publications

One of the largest herring gull (Larus argentatus} nesting populations on the Great Lakes is located in an urban setting on Sandusky Bay in the Ohio portion of Lake Erie. The survey reported here, carried out in 1989, indicated a population of 4,250 nests. The population has expanded from a focal point on Turning Point Island to coal piles at the Lower Lake Dock Company, rooftops in downtown Sandusky and breakwalls near Cedar Point. Comparison with data from a survey performed in 1976 indicates the population has grown at an average annual rate of 11.9% during the past 13 years. …

Fisheries Report No 82 - Effects Of Fish Trapping On The Shark Bay Snapper Fishery, M. J. Moran, J. Jenke Oct 1989

Fisheries Report No 82 - Effects Of Fish Trapping On The Shark Bay Snapper Fishery, M. J. Moran, J. Jenke

Fisheries Research Reports

Traps have been a controversial method of catching pink snapper Chrysophrys auratus (Sparidae) around Shark Bay, Western Australia, since 1959. The history of the issue and the relevant regulations are reviewed; and results of in­vestigations into specific concerns about trap fishing are reported. Concerns of ghost-fishing by lost traps have been largely allayed by underwater TV film of snapper escaping from a standard snapper trap.

A major concern was that traps might physically damage the benthic fauna, e.g. corals. A TV survey showed that while fragile hard corals are abundant in shallower water nearby, the deeper snapper grounds themselves are …

Controlling Roosting Starlings In Industrial Facilities By Baiting, Bernice U. Constantin, James F. Glahn

Wildlife Damage Management Conference

During the winters of 1987-88 and 1988-89 a study was conducted to evaluate the potential of DRC-1339 baiting for controlling roosting European Starlings (Sturnus vulgarus) at Tennessee Eastman Company's chemical manufacturing plant in Kingsport, Tennessee. In 1987-88 Starlicide CompleteR (1% DRC-1339 treated poultry pellets diluted 1:9 with untreated poultry pellets) was used in preroosting congregating areas adjacent to the roost. In 1988-89 Starlicide CompleteR and DRC-1339 treated bread were used in bait containers placed in the roosting structure. Although 90 lbs of Starlicide CompleteR was consumed during 1987-88, bait consumption was sporadic and no appreciable change in the …


A Fencing Technique To Reduce Raccoon Feeding Damage To Sugarcane Research Plots, Hugh P. Fanguy, Dwight Leblanc Sep 1989

A Fencing Technique To Reduce Raccoon Feeding Damage To Sugarcane Research Plots, Hugh P. Fanguy, Dwight Leblanc

Wildlife Damage Management Conference

Damage caused by the feeding of raccoons (Procyon lotor) on stalks of sugarcane (Saccharum sp.) has occurred for several years on the 200-acre U.S. Department of Agriculture, Agricultural Research Service (USDA-ARS) research farm located near Houma, Terrebonne Parish, Louisiana. Damage begins when sugarcane mature internodes begin to from in late June and early July, and continues until the completion of harvest in late December. Raccoons appear to prefer varieties having low fiber and/or high sugar content and can severely damage these varieties (personal observation). Depredation by these animals frequently result in loss of data as preferred …

Animal Damage Control And The Wildlife Profession, Gary J. San Julian

Wildlife Damage Management Conference

Conflicts between man and wildlife have always been a part of our history. We have tried to control the damage caused by wildlife and found that this was not always in the best interest of the resource. The role of animal damage control in our profession has changed and so has the public's view of it. As professionals we must strive to explain the need and value of wildlife damage management to our peers, the public and our detractors. This can be accomplished by participation in our professional organizations, the presentation of papers at scientific meetings, and open discussion of …


Survey Of Mississippi Catfish Farmers On Means, Effort, And Costs To Repel Fish-Eating Birds From Ponds, A. R. Stickley, K. J. Andrews Sep 1989

Survey Of Mississippi Catfish Farmers On Means, Effort, And Costs To Repel Fish-Eating Birds From Ponds, A. R. Stickley, K. J. Andrews

Wildlife Damage Management Conference

Eighty-seven percent of 281 Mississippi catfish farmers felt that fish-eating birds were enough of a problem to warrant harassment. Farmers estimated that they spent an average of 2.6 man-hours per day harassing birds at an average annual cost of $7400. Sixty percent of the farmers who harassed birds did so by driving around the ponds and firing at birds to repel them. Propane exploders and pyrotechnics were also used. Pyrotechnics were judged the most effective repellent technique. The cost of bird harassment according to these farmers is $2.1 million. The value of fish loss to cormorants alone is roughly estimated …


A Review Of The Status Of Bird Management Products And Devices In The United States, Charles W. Areson Sep 1989

A Review Of The Status Of Bird Management Products And Devices In The United States, Charles W. Areson

Wildlife Damage Management Conference

Commercial urban /industrial structural pest bird control is approaching a time of crisis. Several long-standing toxicants that have been used as a major part of pest bird control programs are either suspended, at risk of suspension, or have had their production terminated by the manufacturer. "Environmental groups" are up in arms about the use and misuse of pesticides. Lawsuits have been filed to stop the use of some products, and political pressure has brought about reviews of some pesticide products on both the state and federal levels. EPA has seemed to have a "get tough" policy in its reregistration guidelines, …

Boundaries and Water: Allocation and Use of a Shared Resource (Summer Conference, June 5-7)

Conference organizers and/or faculty included University of Colorado School of Law professors David H. Getches, Lawrence J. MacDonnell and Charles F. Wilkinson.

Boundaries and Water: Allocation and Use of a Shared Resource is the topic of the Center's annual summer program on water this June. Most of the major rivers in the western United States are shared between two or more states. Often tribal governments play an important role in water allocation and use decisions. International considerations also may be involved in some cases. These interjurisdictional issues extend to groundwater as well as surface water.

This conference will provide the …

Temporal And Spatial Patterns Of Abundance Of Age 0 Threadfin Shad (Dorosoma Petenense) In Overton Arm, Lake Mead, William Lee Pelle Jun 1989

Temporal And Spatial Patterns Of Abundance Of Age 0 Threadfin Shad (Dorosoma Petenense) In Overton Arm, Lake Mead, William Lee Pelle

Publications (WR)

Temporal and spatial patterns of age 0 threadfin shad (Dorosoma petenense) abundance and growth, in the Overton Arm of Lake Mead, were examined to evaluate the effects of resource availability on the young fish. This was part of a larger, game fishery enhancement study (Lake Mead Fertilization Project), designed to assess feasability of increasing survivorship of larval/juvenile shad by boosting phosphate levels, thereby increasing algal and zooplankton biomass, during the shad spawning period. Shad are the primary forage base for the striped bass (Morone saxatilis) and black bass (Macropterus salmoides) fisheries. Weekly samples were …


Characterization Of Activated Sludge Immobilized In Calcium Alginate Gel With Respect To Biodegradation Of 2-Chlorophenol And Benzene, Manjari Singh May 1989

Characterization Of Activated Sludge Immobilized In Calcium Alginate Gel With Respect To Biodegradation Of 2-Chlorophenol And Benzene, Manjari Singh

Theses

Activated sludges acclimated with phenol and 2-chlorophenol in one case, and a mixture of benzene, toluene, and o, in and p-xylene in another case, were characterized for biodegradation of 2-chlorophenol and benzene, respectively. Activated sludge was obtained from the Parsippany-Troy Hills Water Pollution Control Plant (NJ).

For both cases colonies were isolated before acclimation, after acclimation, and at the end of biodegradation studies. Since the unacclimated group was the same in both cases, there were a total of five different groups for which characterization was carried out.

For all the five groups together, a total of 54 isolates were obtained …


Investigation Of Major Mutagenic Substances In Airborne Particulate Matter : Biologically-Driven Analysis Of Fractions And Analysis Of Polycyclic Aromatic Hydrocarbons (Pahs) Nitro-Pahs And Other Classes Of Compounds, Jung-Hen Lwo May 1989

Investigation Of Major Mutagenic Substances In Airborne Particulate Matter : Biologically-Driven Analysis Of Fractions And Analysis Of Polycyclic Aromatic Hydrocarbons (Pahs) Nitro-Pahs And Other Classes Of Compounds, Jung-Hen Lwo

Theses

A modified fractionation scheme involving acid-base partitioning and silica gel column chromatography has been used as the first step in the bioassay-directed search for significant levels of mutagenic compounds in extracts of inhalable (IP10) ambient air particulates. The biologically "hot" fractions were separated and analyzed chemically or subfractionated to isolate and concentrate "hot" subfractions which were then chemically analyzed by GC/MS FTIR, and HPLC equipped with UV, Fluorescence and Photodiode Array UV detectors.

The Ames assay of mutagenicity has involved the unactivated TA98 strain of Salmonella and enzyme-activated (TA98+S9) assays. In addition, some assays have been performed in this present …

The Benefits Of Weaning Cattle In The Kimberley, David Pratchett, Stuart Young May 1989

The Benefits Of Weaning Cattle In The Kimberley, David Pratchett, Stuart Young

Animal production and livestock research reports

The Kimberley region was populated with Shorthorn cattle from Queensland and New Sonth Wales in the 1880's. The descendants of these cattle known as Kimberley Shorthorn are still the predominant breed in the region. The relatively poor performance of these cattle under the harsh Kimberley conditions and the fact that changing the genotype can improve productivity was recently published (Pratchett D. WADA Journal No. 4 1988)

While the adoption of Bos indicus breeds is the correct move, improved husbandry can also increase the productivity of the Kimberley Shorthorn cow. The majority of cattle in the Kimberley are not weaned. Sometimes …

Total Maximum Daily Loads And Waste Load Allocations For Las Vegas Bay: Rationale And Calulations, State Of Nevada: Division Of Environmental Protection

Publications (WR)

In September 1987 the Nevada Division of Environmental Protection revised Water Quality Standards for Las Vegas Wash (LVW) and Lake Mead. Standards were set for chlorophyll-a and unionized ammonia in Las Vegas Bay (LVB) (NDEP 1987). The 1986 and 1987 LVB data showed non-achievement of both the chlorophyll-a and unionized ammonia standard which triggered an analysis of total phosphorus and total ammonia Total Maximum Daily Loads and Waste Load Allocations which are presented in this report. This report is separated into three sections: 1. 1987 Las Vegas Bay Water Quality Conditions and Seasonal Periodicity. 2. Concentration Estimates at Northshore Road …


A Porpoise, Australophocaena Dioptrica, Previously Identified As Phocoena Spinipinnis, From Heard Island, Robert L. Brownell Jr., John Heyning, William Perrin Apr 1989

A Porpoise, Australophocaena Dioptrica, Previously Identified As Phocoena Spinipinnis, From Heard Island, Robert L. Brownell Jr., John Heyning, William Perrin

United States Department of Commerce: Staff Publications

Guiler, Burton and Gales (1987) reported a cranium (Tasmanian Museum No. A141 1) they identified as belonging to Burmeister’s porpoise, Phocoena spinipinnis Burmeister, 1865 from Heard Island (53°S 73°30’E). They noted that P. spinipinnis was previously known only from the cold-temperate coastal waters of South America and claimed that this cranium was evidence that the species has a much wider distribution than previously known. We have examined the photographs and details of their specimen and re-identify it here as Australophocaena dioptrica (Lahille, 1912) (family Phocoenidae).

Barnes (1985) listed several features that distinguish the skulls of species within the subfamily Phocoenoidinae …
