A Comparative Study Of A Salt Water Impoundment With Its Adjacent Tidal Creek Pertinent To Culture Of Crassostrea Virginica (Gmelin), William D. Anderson Iii Oct 1976

A Comparative Study Of A Salt Water Impoundment With Its Adjacent Tidal Creek Pertinent To Culture Of Crassostrea Virginica (Gmelin), William D. Anderson Iii

OES Theses and Dissertations

Certain physical, chemical and biological characteristics associated with the culture of subtidal Crassostrea virginica were assessed in a salt water impoundment and its adjacent tidal feeder creek. Large seed oysters (initial y = 57.3 mm) were transferred from a somewhat polluted estuary of Charleston Harbor to floating, mid-water, and bottom hardware cloth trays (200/tray) in a four hectare pond. Identical trays at comparable depths were placed in the tidal creek and each location was sampled monthly for growth and survival. Surface and bottom water samples were collected weekly throughout the study and hourly during four seasonal 25 hour stations. Standard …

Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith May 1976

Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the feeding responses of mule deer to a system of spring livestock grazing. The specific purposes were 1) to determine botanical composition of diets selected by mule deer on a winter range subjected to previous spring grazing by sheep compared to one with no sheep grazing and 2) to develop a basis for predicting selection of individual plants by deer, based on physical characteristics of the plants and the species and physical proximity of associated plants.

The study was conducted within the framework of a completely randomized experimental design with two treatments. Variables controlled for each unit …


Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego May 1976

Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nomadic pastoralism has been the traditional method of utilizing grazing resources in arid and semi-arid regions of Africa. However, increased sedentarization accompanied by growing human and animal populations during the past two decades is thought to be accelerating the desertification process, or desert expansion. The specific interactions of the grazing animal with this process has been speculated upon but not studied in detail. A comparative study was initiated during the spring grazing season of 1974 to determine sheep and goat nutritional and production responses, as well as patterns of vegetative selection and utilization under the pastoral system currently employed in …

Recommendations Of Alternative System Plans And Transmission Corridors For The Dickey/Lincoln School Hydroelectric Project, Vtn Environmental Sciences (Firm), Interior

Dickey-Lincoln School Lakes Project

The regional scope of this study (a three state area of approximately 33,000 square miles) necessitated an initial investigation to determine what data was available. Known and potential sources of data were identified through the use of the Environmental Data Reconnaissance Report* prepared by Comitta Frederick Associates for the United States Depart-ment of the Interior in March 1976. The collected data was then analyzed for its accuracy, reliability, mappability and compatibility with the scope of this study.

Transmission Planning Summary : Dickey-Lincoln School Lakes Project Transmission Studies, United States Department Of Interior

Dickey-Lincoln School Lakes Project

This report summarizes the results of system planning, environmental, and location studies for transmission facilities associated with the proposed Dickey-Lincoln School Lakes Project in northern Maine. The studies recommend the construction of two 345-kV transmission circuits from a substation near the project along a route through western Maine into northern New Hampshire and Vermont. The plan will integrate the power produced by the project into the New England Power Pool Transmission System. Five alternate integration plans were identified and studied. Of the five plans, the recommended plan, which calls for the lines to be suspended from a single row of …

Terrestrial Ecology Of The Dickey-Lincoln School Lakes Project, Corps Of Engineers, New England Division, Environmental Research & Technology, Inc

Dickey-Lincoln School Lakes Project

This introduction of the St. John River watershed is situated in a transitional zone between the Boreal Forest Formation and the Eastern Deciduous Forest Formation. Second-growth forests representative of these two ecosystems cover extensive areas of the project site. The boreal forest forms a broad transcontinental belt in northern North America and Eurasia, with southern montane extensions. This northern forest is characterized by evergreen, coniferous trees, predominately spruce-fir The eastern deciduous forest, composed of broad-leaved hardwoods, extends throughout the eastern United States except Florida (Dasmann, 1968; Oosting, 1956).

Chlorofluorocarbon Effects On Cardiac, Pulmonary, And Respiratory Patients, Mildred E. Olson Jan 1976

Chlorofluorocarbon Effects On Cardiac, Pulmonary, And Respiratory Patients, Mildred E. Olson

Journal of the Minnesota Academy of Science

Research results from studies of the physiological effects of aerosal propellants on animals and people are summarized. The papers selected for this summary were published between 1968 and 1975. Effects of the 15 chlorofluorocarbons used as propellants have been recorded on the cardiac, pulmonary and respiratory functions of a number of animal species as well as man. The fifteen propellants have been classified into four groups on the basis of their degree of toxicity. Fluorocarbon 11, the most frequently used propellant, is in group 1, the most toxic. The relative toxicity of each of the 14 other propellants compared with …

Laboratory Apparatus For Providing Diel Temperature Regimes For Aquatic Animals, Wayne A. Wurtsbaugh, G. Davis Jan 1976

Laboratory Apparatus For Providing Diel Temperature Regimes For Aquatic Animals, Wayne A. Wurtsbaugh, G. Davis

Watershed Sciences Faculty Publications

In studies of the effects of elevated temperature on aquatic organisms, little emphasis has been placed on modeling the fluctuating temperatures to which organisms are exposed in nature. To some extent this may be related to problems of design and maintenance of apparatus for fluctuating temperature control. The complexity of apparatus used to provide cycled temperatures has ranged from manually controlled valves for introducing water of different temperatures into aquariums (Kelso 1972), to a complex and expensive feedback system, regulated by rotating cams, that controls the temperature of influent water (Honeywell Cam Programmer Thermometers, Fort Washington, Pennsylvania). To facilitate studies …

Oyster Spatfall On Shellstrings In Virginia Rivers: 1975 Annual Summary, Dexter S. Haven, Paul C. Kendall Jan 1976

Oyster Spatfall On Shellstrings In Virginia Rivers: 1975 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made from oyster shells strung on wire and · suspended from stakes on public and private beds. The number of spat on shells are counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur. Shells .planted just before the period of maximum set have the best chance of getting a good strike.
