Impact Of Dredging In Tampa Bay 1976, Roy R. Lewis Iii

Reports

During the last 100 years four major types of dredging have impacted the bay: channel deepening, maintenance dredging, shell dredging, and dredging for landfill construction. These landfills have resulted in the loss of 44% of the original marine wetlands bordering Tampa Bay. Recent environmental concerns have halted landfill dredging and severely restricted maintenance dredging.

A Review Of Coyote Control Research, Donald S. Balser

Vertebrate Pest Conference Proceedings: 6th (1974)

Research on coyote control has lagged behind operational control for several decades. With the current controversy over toxicants and control of coyotes, attention has suddenly been given to the research needs of the problem. In the past research on annual damage problems, particularly predators, was concentrated on coming up with new lethal methods. The picture has changed with a definite need to study the entire problem, including the measurement of losses, the ecology of predators and prey, their behavior, and means of solving loss problems by non-lethal methods or mechanical protection. In any lethal control research, selectivity must be emphasized. …

A Review Of Rodent Control Programs In New York State, Joe E. Brooks

Vertebrate Pest Conference Proceedings: 6th (1974)

The history of rodent control programs in New York State is reviewed, beginning with state-funded efforts in August, 1967. In 1969, Federal rodent control grant funds were used to establish four Model Cities programs. At its peak in 1970, programs were active in 18 counties, eight cities and villages, and in six Model Cities areas. The program encompasses all the major metropolitan areas of the state, serving some nine million persons.

As part of the state program, the Rodent Control Evaluation Laboratory was established to investigate chemosterilants as a means of rodent control and to develop knowledge of pest rodent …

Limnological, Ichthyological, And Parasitological Investigations On Arkansas Reservoris In Relation To Water Quality, John S. Carter, Carl E. Hoffman, Larry L. Olmsted, Raj V. Kilambi, Donald G. Cloutman, David A. Becker

Arkansas Water Resources Center Technical Reports

Lake Fort Smith, a 525 acre (212 ha) reservoir, was impounded in 1936 as a water supply for the city of Fort Smith. The reservoir is located on Clear Creek (Frog Bayou), a tributary of the Arkansas River, in the Boston Mountains 28 miles (45 km) northeast of the city of Fort Smith in Crawford County, Arkansas. A map and morphometric characteristics of Lake Fort Smith are given in Fig. 1 and Table I (Hoffman, 1951; Nelson, 1952). In 1956 Lake Shepherd Springs, a 750 acre (304 ha) impoundment, was created one mile upstream of Lake Fort Smith (Rorie, 1961). …

The Effects Of Fenthion On A Nesting Population Of Quelea During Experimental Control By Aerial Spraying, Jeffrey J. Jackson, Peter O. Park

Bird Control Seminars Proceedings

Quelea quelea is probably the most important avian pest of cereal crops in the sahelian areas of Africa. Its depredations reduce the cereal production of many African nations that lie within its range. To prevent this damage, bird control organizations carry out campaigns to reduce their numbers. Frequently these efforts have given poor crop protection for the cost of control because of inadequate control technology. Factors contributing to the difficulty of carrying out this kind of control are the migrations of the birds which are still incompletely understood, the inaccessability of many nesting areas, the relatively high reproductive potential of …

A Field Study Of Selected Ecological Properties Of Boca Ciega Bay And Adjacent Gulf Of Mexico, Geo-Marine, Inc.

Reports

This report describes a quantitative study of selected environmental parameters in a portion of Boca Ciega Bay and in the Gulf of Mexico adjacent to Johns Pass. The investigation included an analysis of hydrography and water quality during the period 14-20 February 1973. The objective of the study was to assess the present marine environment in order to judge the ecological feasibility of discharging tertiary treated sewage effluent into Boca Ciega Cay or secondary treated effluent into the Gulf of Mexico. The discharge would come from the proposed expansion of the South Cross Bayou sewage treatment plant.

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 …

Trace Metal Analysis Of Barren River And Nolin River Reservoirs By Atomic Absorption Spectroscopy, Mary Jo Kennedy

Masters Theses & Specialist Projects

This research was part of a project underway at Barren River and Nolin River Reservoirs in south-central Kentucky. The research was partially supported by a grant through the Sport Fishing Institute, Washington, D.C.

The study reported herein was concerned with the analysis of trace metal concentrations in the two reservoirs. It is believed that the fish population may in part depend upon the trace metals present in the water. It is anticipated that the data presented in this paper will eventually be correlated with the biology studies of the reservoirs being carried out by the Department of Biology of Western …

Birds And Airports, Erwin W. Pearson

Vertebrate Pest Conference Proceedings: 3rd (1967)

For all practical purposes, research in this country on the problem of bird hazards to aircraft began in 1960 with the crash of an Electra turboprop that carried 62 people to their deaths and was attributed to ingestion of starlings into the engines. In this paper I intend to review the problem and present some of the answers found by investigators in this country and, to lesser extent, abroad. The discussion will be roughly divided into two parts: 1) what: causes the problem, when, and where; and 2) what has been and is being done at airfields to reduce it. …

Ecological Control Of Bird Hazard To Aircraft, V. E. F. Solman

Bird Control Seminars Proceedings

The Canadian Wildlife Service has had twenty-five years experience with the problem caused by bird contacts with aircraft. I experienced my first bird strike, while flying as an observer on a waterfowl survey in August, 1940. Officers of the Service investigated bird problems at airports at Yarmouth, Nova Scotia, and Cartierville, Quebec, in the late 1940's. Those incidents involving gulls and low speed piston-engined aircraft caused minor damage to the aircraft but considerable disturbance to the operators. As aircraft speeds increased and airports became more numerous and busier the problem increased in extent and complexity. By 1960 it was apparent …

The Nebraska Sandhill Lakes: Their Characteristics And Fisheries Management Problems, D. B. Mccarraher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

A brief look at the map of Nebraska will readily point out the obvious fact that the sandhills comprise a considerable portion of the land area of the state. To be more precise, an area encompassing around 20,000 square miles or about one quarter of the total state area. This is indeed a vast prairie region long noted for its fine cattle and native hay crops. It is a region of vegetative dune sandhills, sandy basins and valleys, exposed ground water, spring seep lakes and marshes. Since much is already known concerning the land portion of the sandhills it is …

Biological Indices Of Water Pollution, With Special Reference To Fish Populations, Peter Doudoroff, Charles E. Warren

Other Publications in Wildlife Management

A number of investigators have very recently published discussions having to do with biological indices and biological measures of water pollution (1) (2) (7) (13) (14) (15) (16) (26) (27) (28) (29) (30) (36) (38). Fjerdingstad (12) has discussed some of the pertinent European literature. The fundamental concepts presented by these authors are not original, for the idea that aquatic organisms can be useful "indicators" of environmental conditions, and particularly of the degree of pollution of water with organic wastes, has a long history (12). Because of certain novel features and the relatively wide scope of the studies, and the …

Stream Pollution- Aquatic Macro-Invertebrate Communities As Indicators Of Organic Pollution In Lytle Creek, Arden R. Gaufin, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

Year-round field studies of the com position and ecology of stream communities associated with the purification of organic wastes in streams were initiated on Lytle Creek in October, 1949. This creek, which is located about 45 miles northeast of Cincinnati, Ohio, is a tributary of the Little Miami River. Its drainage basin comprises 27 sq. mi., a third of which is contained within the city limits of Wilmington, Ohio, a city of some 7,412 persons
