KWRRI Research Reports
A model for predicting leaf temperatures during an off-on mist cycle is presented. The model uses a combination of energy budget and aerodynamic techniques. The model was tested for dry leaf temperature and evapotranspiration predictions using average hourly data from Arizona. The accuracy was good. It was also tested for dry leaf temperature predictions using two to three minute data with a widely varying net radiation. When reasonable values of stomatal resistance were used, the agreement was again good.
The model was tested for prediction of wet leaf temperature prediction with a ten minute on, fifty minute off mist irrigation …

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 …

Deepwater Ports, Ronald Joel Calhoun
Marine Affairs Theses and Major Papers
This paper is designed to provide an overview of the oil energy import problem and an analysis in a case study format of the various deepwater port alternatives for direct shipment and transshipment of foreign crude oil. This work was initiated prior to the recent expanded energy crisis and although touches on the problems of dependency of the United States to foreign crude oil, the various alternative sources of energy, the essence of this paper is an analysis of the various deepwater port considerations for the direct or indirect importation of foreign crude oil; specifically along the Gulf Coast.

United States Bureau of Land Management: Staff Publications
The objective of this report is to provide BIM personnel with the latest and most up-to-date information on rare or endangered species occurring on the public domain. This will provide a tool for improved understanding of the interrelationships between the species and its environment and encourage an end product of enlightened land management which will fully consider the species welfare in all management decisions.
How To Build Marine Artificial Reefs, R. O. Parker Jr., R. B. Stone, C. C. Buchanan, F. W. Steimle Jr.
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 …

Biochrome Analysis As A Method For Assessing Phytoplankton Dynamics Phase I, Richard L. Meyer
Arkansas Water Resources Center Technical Reports
Selected chemical, physical and biological parameters were determined for a man-made lake, Beaver Lake, on the White River of Arkansas and Missouri. The research program determined the qualitative and quantitative aspects of the temporal and spatial distribution of the algal subcommunities. It was determined that the epipelic, epilithic, epizooic and metaphytic subcommunities had little influence on the euplanktonic subcommunity. The relationship between the qualitative and quantitative analysis of the biochromes chlorophyll-a, -b, and -c and the phytoplankton species clustered into biochrome sets is discussed. The temporal and spatial distributional patterns of temperature, oxygen, ammonia-N, nitrate-N, ortho phosphate-P and silicates are …
