Studies On The Causes Of Tree Distribution In A Forest Type In The Dismal Swamp National Wildlife Refuge, Thomas A. Janszen

Biological Sciences Theses & Dissertations

Vegetational composition and environmental parameters were analyzed in a forest type of the Dismal Swamp. A 0.5 ha forest stand was divided into 200 5 x 5 meter contiguous quadrats and the tree size classes were precisely mapped. Fifty soil samples were analyzed for texture, pH, and major nutrients. A topographic map was constructed with precision to 0.01 ft. Analysis of variance tests showed non-randomness to exist in soil texture and nutrient content while homogeneity tests showed non-randomness in distribution of some woody species. Factor analysis indicated no significant correlations between soil quality, topography, and woody species. Findings indicate that …

An Ecological Study Of The Craney Island Disposal Area In Hampton Roads, Virginia, David Wallace Laist

Biological Sciences Theses & Dissertations

A one year ecological study was conducted on the Craney Island Disposal Area in Hampton Roads, Virginia. This study attempted to identify the flora and fauna inhabiting the spoil deposits and trace the development of communities from the time of deposition through the initial stages of succession.

One hundred and ninety-two species were identified including 48 vascular plants, 66 insects, 48 birds, 18 species of algae, 4 crustaceans, and 8 vertebrates. The study area was divided into six zones based on substrate characteristics and species composition. The successional patterns and biotic interactions within each zone were discussed.

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. …

Animal Damage Control Research–"Are Present Priorities Based On Actual Need?", Richard N. Smith

Vertebrate Pest Conference Proceedings: 6th (1974)

Priorities regarding Bureau of Sport Fisheries and Wildlife vertebrate damage control research are in most cases based on actual need. Need is influenced by economic, political, legislative, and biological incentives. These incentives affect private industry, state and local governments, academia, and the federal government but in different ways. The Bureau of Sport Fisheries and Wildlife has 24 percent of its wildlife research budget invested in vertebrate damage control research. Its programs deal with predators, birds, and small mammals and research programs are problem oriented. Priorities are generally developed within the organization and are usually determined by biological need.

Pheasant Management Recommendations, William L. Baxter

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

Information on the life history and ecology of the ring-necked pheasant was collected on two, nine-square-mile study areas in Clay County, Nebraska, from 1954 through 1964. The study was designed to provide basic data that would allow scientifically based management decisions to be made for the maintenance and enhancement of ring-neck populations.

Findings indicate certain steps should be taken to improve pheasant populations on state-owned or controlled lands, as well as recommendations to improve habitat for pheasant populations on land not controlled by the Game Commission, These secondary proposals have statewide ramifications and offer potential for significantly improving pheasant populations …

How To Build Marine Artificial Reefs, R. O. Parker Jr., R. B. Stone, C. C. Buchanan, F. W. Steimle Jr.

United States Department of Commerce: Staff Publications

Artificial reefs provide or improve rough bottom habitat and offer fishery scientists and administrators an effective technique to conserve and develop coastal fishery resources. With careful planning and organized efforts, local reef committees can build reefs to improve fishing and contribute to the recreational and financial growth of coastal communities. Advice and procedures are presented for: 1) selecting construction materials, 2) determining a suitable reef site, 3) obtaining permits, 4) buoying the reef, and 5) preparing, transporting, and placing reef-building materials. Included in appendixes are instructions for preparing permits, addresses of Federal and State agencies involved in approving or funding …

Environmental Evaluation Report On The Big Mulberry Creek Basin In Franklin, Madison, Newton, Johnson And Crawford Counties, Arkansas, Edward E. Dale Jr.

Arkansas Water Resources Center Technical Reports

The environmental evaluation report which follows is based on information supplied by the Corps of Engineers, Little Rock District, available literature, field observations made during the summer of 1972, and results of research now in progress on natural features of the Big Mulberry Basin. Since most major dams, levees, and flood retarding structures now in existence in the Ozarks have been constructed since about 1940, opportunities to make long term studies of their effects have been limited. Also, the natural vegetation, fauna, and archeology of the Big Mulberry Basin have not been extensively investigated, but available sources provide enough information …

KWRRI Research Reports

Samples of water, bottom fauna, and fishes were collected from 66 stations in the Salt River and one of its principal tributaries, the Beech Fork and its tributary, the Chaplin River, Kentucky. Precipitation ranged from 38.86 inches (1969) to 58.04 inches (1970), an increase of nearly 50 percent with marked fluctuations in discharge. Intensive comparisons of phosphates, sulfates, specific conductance, total alkalinity, total hardness, and turbidity showed the streams to be relatively clean and healthy. Nearly 300 different kinds of benthic organisms and other macroinvertebrates have been collected and identified from the basin. Detailed studies of caddisflies and stream drift …

Marine Affairs Theses and Major Papers

The U.S. Army Corps of Engineers is one of the largest single Federal agencies involved in the planning, design and construction of public waterborne transportation facilities. A critical review of a typical corps of Engineers survey report on the improvements to a harbor should provide an insight to the means of allocating the costs and benefits resulting from government expenditures. The purpose of this paper is to review this process using as a vehicle the proposed improvements to the navigation channel at New London, Connecticut

Reproduction In The Red Squirrel (Tamiasciurus Hudsonicus) In Colorado, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Information on reproduction of the red squirrel (Tamiasciumrs hudsonicus) can be gleaned from studies in the northeastern United States (Klugh, 1927; Hamilton, 1939; Layne, 1954) and in western Canada (Miller, 1970; Smith, 1968; Kemp and Keith, 1971; Wood, 1967). However, there is a paucity of information on reproduction from the mountainous regions of the western United States. This paper presents reproductive information on the red squirrel from Colorado and helps fill this void. In addition, the reproductive strategy of red squirrels is briefly compared with that of snowshoe hares.

The Interspersion Index As A Technique For Evaluation Of Bobwhite Quail Habitat, William L. Baxter, Carl W. Wolfe

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

Some forty years ago, the concept of habitat interspersion was advanced by Aldo Leopold (1931). Indicating then that "we are only on the threshold of an understanding of the ecology of game species," Leopold went on to postulate his law of interspersion which recognized that “game is a phenomenon of edges.” Although the validity of Leopold's premises has been documented both directly and indirectly many times in the past four decades, the complexity and frustration in describing ecological diversity of game range has continued to pose a problem for wildlife managers since 1931.
