Algal Growth And Decomposition: Effects On Water Quality, Edward G. Foree, John S. Tapp Jr.

KWRRI Research Reports

The chemical composition of algae grown in batch culture depends mainly on environmental conditions, nutrient availability, presence of predators, cell age, and species. The effects of nutrient availability and cell age on the composition of three unialgal cultures (algae + bacteria) and one hetergeneous culture (algae + bacteria + microscopic animals) were evaluated. The cultures were grown in batch culture under both nutrient-abundant and nutrient deficient conditions and the changes in compositions were observed. Luxurious uptake where nutrients are incorporated into cellular protoplasm at levels greater than those necessary for growth, and super-luxurious uptake, where some nutrients are stored rather …

A Permanent Type Poison Station For Porcupine Control, William A. Neitro

Vertebrate Pest Conference Proceedings: 4th (1970)

A method has been devised to protect the poison strychnine-salt blocks used in controlling porcupines, Erethizon dorsatum, from the weather, killing of non-target animals and vandalism. An aluminum poison bait station has been developed which is light weight, durable, camouflaged, and safe. These structures are easily constructed and are relatively inexpensive when longevity is considered. Porcupines are controlled effectively and economically using this method

Carbamate Baits Discourage Blackbirds From Using Feedlots, Paul P. Woronecki, Joseph L. Guarino, Jerome F. Besser, John W. De Grazio

Vertebrate Pest Conference Proceedings: 4th (1970)

Red-winged blackbirds (Agelaius phoeniceus) have been discouraged from using cattle feedlots near Denver, Colorado, by baiting alleys with cracked corn treated with an aversion-producing immobi1izing agent, DRC-736 [4-(methylthio)-3,5-xylyl N-methylcarbamate]. In three studies, large populations of redwings were reduced 70% - 98% within a few days and protection lasted about a month. In a fourth study, simultaneous baiting of three heavily used feedlots reduced redwing use by more than 90% within hours and was apparently responsible for these birds abandoning their roost and relocating in areas where they caused little trouble. Mortality was low (less than 5% of affected redwings in …

On behalf of the California Vertebrate Pest Committee, which sponsors these conferences, I wish to thank all of the speakers for their contribution to the program and the session chairmen who kept the meeting moving so smoothly. We would like to extend a special thanks to the speakers and participants who have come from other countries to share with us some of their knowledge concerning vertebrate pest problems and their solutions. Hopefully, the acquaintances made here and the exchange of information with our colleagues from distant places will be the beginning of long-lasting friendships and will foster better communications between …

Surfactants As Blackbird Stressing Agents, Paul W. Lefebvre, John L. Seubert

Vertebrate Pest Conference Proceedings: 4th (1970)

Applications of wetting-agent solutions produce mortality in birds. The exact cause of death is undetermined, but it is believed that destruction of the insulating qualities of the plumage permits ambient cold temperatures and evaporation to lower the body temperature to a lethal level. The original concept of using these materials as bird-control tools was developed in 1958 at the Patuxent Wildlife Research Center, Bureau of Sport Fisheries and Wildlife, Laurel, Maryland. Early field trials by personnel of the Division of Wildlife Services and the Denver Wildlife Research Center indicated that ground-application techniques had promise, but limitations of the equipment precluded …

The Impact Of Conflicting Uses Of The Coastal Zone On Naval Planning And Policy, Thomas M. Ward Jr.

Marine Affairs Theses and Major Papers

A brief review of the origin of the Navy's coastal real estate holdings and a method of approach to analysis of the present conflicts of multiple use of the coastal zone isused to assess the needs for continued use of these holdingsand provide valid arguments for retention of those that are required. The study also presents a method of analysis that could provide a means for anticipating or resolving conflicting uses of Navy held real estate. The pressure created by an increasing population combined with a reduction of the armed forces necessitates a review of all Navy coastal zone property …

Emergency Chlorination Of Farm Water Supplies, H C. Hughes

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

TOWARDS the end of summer (and especially in a drought) the risk of water in dams, soaks, wells or tanks becoming polluted is increased.

Bore water is much less likely to be affected unless the bore is poorly sited near a farm building, such as a shearing or milking shed, a pig pen, or a septic tank system.

Factors Affecting Relocation In Response To Reservoir Development, Rabel J. Burdge, Richard L. Ludtke

KWRRI Research Reports

The focus of this paper is on the question of how rural people anticipate forced moves as a result of flood control projects and how they change their life in accepting separation from familiar surroundings.

A model of faced migration is presented which sees the variables of socioeconomic status, knowledge of reservoir projects, vested interests and the degree of identification with place of affected persons as producing differential apprehension over moving. Differential apprehension is then seen as producing different attitudes toward the project which will influence the type of migration plans.

To test this model of forced migration, data were …

Anticipations Of Change: A Socio-Economic Description Of A Kentucky County Before Reservoir Construction, Charles Robert Smith

KWRRI Research Reports

In the past the construction of large reservoirs in the United States has been evaluated largely in terms of the economic benefit they bring to the area where they are constructed and to the nation. Where human populations are involved, however, a host of social changes occur, many of which fundamentally alter the way of life of a people.

This report is part of a larger study which aims at analyzing the social costs and benefits of reservoir construction. The project is long range in that studies are to be carried out before, during, and after construction. This report concentrates …

Evaluation Of The Social Impact Of Reservoir Construction On The Residential Plans Of Displaced Persons In Kentucky And Ohio, Richard L. Ludtke, Rabel J. Burdge

KWRRI Research Reports

The states of Kentucky and Ohio have numerous reservoir projects at various stages of planning and construction. Each of the projects produces substantial social impact for the residents of the area and particularly for those persons affected by a loss of property and homes. This impact is not uniform in that people respond differently to displacement and the methods of adjusting relocation are known to differ among people.

This research was initiated to develop and test a model for explaining migration under such conditions. The model includes a consideration of people's potential for transferring existing statuses to new residences, the …

Systems Analysis Of Hydrologic Problems, J. Paul Riley, Diana Averett

Reports

Introduction: Increasing national and international interest in water resources in recent years has stimulated much new activity and progress in hydrology. It is now generally recognized that the science of hydrology is basic to an understanding of water resources problems and to planning for water resources development. Accompanying this demand upon the science of hydrology is an urgent need for improved education at the university level. In resopnse to this need for improved education, the First International Seminar for Hydrology Professors was held at Urbana, Illinois, in July 1969. The Second International Seminar was held at Logan, Utah, during August …

An Examination Of Approximately Simultaneous Salt Lake Valley And Cache Valley Clearing (Ventilation) Indexes, George W. Reynolds, William Mcneill, Floyd Johnson, Janet Cleary

Reports

The Clearing Index is a numerical estimate of the contamination dispersal capability of the atmosphere. Between July, 1969, and June, 1970, 192 rawinsonde flights were made in the Cache Valley at approximately the same time as officially scheduled flights at the Salt Lake City Weather Bureau Airport Station. Clearing Indexes were computed from various combinations of Salt Lake Valley and Cache Valley rawinsonde and maximum surface temperature data. These were examined from the viewpoint of recommending a standard procedure for providing Clearing Indexes on a daily basis for Intermountain valleys. The primary conclusions were that: 1. Actual Salt Lake Valley …

A Thermodynamic Analysis Of A Primary Waste Stabilization Pond, David W. Hendricks

Reports

Traditional design practice for waste stabilization ponds is based upon the premise that sufficient photosynthetic oxygen must be produced within the pond to satisfy oxygen requirements of the incoming waste flow. Thus, because algae production is proportional to pond surface area, surface organic loading rate is a principal design criterion (hydraulic detention time is the other) . That a possible adverse energy trade exists in the sequence of coupled reactions (aerobic waste degradation-photosynthesis) has been largely ignored. This work is focused on quantitatively articulating this energy trade, in terms of algae produced vis a vis waste degraded. This is done …

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 …

The Ocean Resource: A Scenario For Its Control, Ronald Poitras

Marine Affairs Theses and Major Papers

As man expands his horizons on planet earth, he is beginning to turn increasingly to the oceans as a source of resources, and at a pace commensurate with the growth of his needs and his technical ability. Traditionally the deep sea has always been a "no man's land," an unlimited source of space to be traversed and used infrequently. A scarcity of natural resources and an abundance of human extensions (i.e. technology) are together making deep ocean seclusion a thing of the past. Increasing use of a particular resource is a limited space sooner or later implies an increasing need …

Beggar-Tick Injury To A Northern Cricket Frog And Two Species Of Minnows, Larry A. Witt, Leonard H. Sisson

Nebraska Game and Parks Commission: Staff Research Publications

Various authors have reported on injury to small fishes by achenes of beggar-ticks (Bidem sp.) Reimers and Bond (1966) reported on injury by beggar-ticks to redside shiners, Richardsonius balteatus and young chinook salmon Oncorhynchus tshawytscha. They suggested that presence of beggar-tick plants along banks of hatchery ponds and raceways might be injurious to young of the most aggressive feeders among fish. Allison (1967) described mortality of fingerling coho salmon, Oncorhynchus kisutch, caused by beggar-tick, B. cernuus, achenes. He noted losses of coho salmon 51 to 90 mm in total length held in hatchery raceways. Dead and …

Virus Movement In Groundwater Systems, William A. Drewry

Arkansas Water Resources Center Technical Reports

The purpose of this study is to investigate the extent to which soil acts as an agent in the transmission of waterborne viruses. Since many waterborne outbreaks of viral diseases have involved small wellwater supplies contaminated by effluents from subsurface wastewater disposal systems, there is a great need for such information. Results of this study show that virus adsorption by soils is greatly affected by the pH, ionic strength, and soil-water ratio of the soil-water system and various soil properties. Also, it is shown that one cannot predict the relative virus adsorbing ability of a particular soil based on the …
