Woodpecker Nesting Habitat In A Prairie River Woodland, J. Barry Parrish

Electronic Theses and Dissertations

Differences in nest site selection of the common flicker (Colaptes auratus), yellow-bellied sapsucker (Sphyrapicus varius), downy woodpecker (Picoides pubescens), and red-headed woodpecker (Melanerpes erythrocephalus) were studied on the Big Sioux River riparian forest of eastern South Dakota during 1980 and 1981. Nest site preferences were compared using two-group stepwise discriminant analysis. Randomly selected potential nest trees showing no previous signs of cavity excavation were included as control groups. The yellow-bellied sapsucker-red-headed woodpecker function was the most efficient in separating groups because both species had specific nest site preferences. Sapsuckers nested only in live green ash (Fraxinus pennsylvanica), characteristically in park-like …

Home Range, Home Range Expansion, Dispersal, And Mortality Of Juvenile Red Foxes In Southeastern South Dakota, Floyd M. Demaray

Electronic Theses and Dissertations

Data from aerial and landowner surveys showed that red fox (Vulpes vulpes) families on the Sinai study area decreased from 13 (5.2 per township) in 1976 to 11 (4.4 per township) in 1977. The majority (88%) of the active red fox dens was located in pastures and idle lands although these cover types constituted only 24% of the available cover. Twenty-nine juveniles and 3 adults were captured and marked during spring, 1976. Trappers and hunters returned 62% of the tags placed on juvenile foxes.

The program will be initiated during a five year period and will be followed by periodic updates. The program's benefits include improved watershed conditions through increased vegetation cover which will consequently reduce erosion. There will be an increase in the amount of rangeland in good condition and a decrease in the amount in poor condition. The rangeland's capacity ot sustain grazing by livestock and big game will also be increased. Wildlife habitat will be maintained or improved throughout …

Summary Utah/Western Colo, 1992 System Study, United States Department Of Energy Western Area Power Administration

All U.S. Government Documents (Utah Regional Depository)

The Utah/western Colorado area of the Rocky Mountain Region has adequate coal and water resources to support additional thermal generation plants beyond those already in service. Also within the region are several sites suitable for large-sized hydroelectric pumped-storage projects for purposes of supplying peaking power. The close proximity of these types of electric generating facilities is desirable in providing offpeak energy during the pumping cycle for the pumped-storage units. Considering that the potential capacity of each type of generation is in the 500 to 1,000 (two units) MW range per site and would require major extra-high-voltage (EHV) transmission developments, it …

The White Perch, Marone Americana (Gmelin) In Nebraska, Gene Zuerlein

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

The white perch, Morone americana (Gmelinl, is a member of the Percichthyidae family. It is a euryhaline species that is common along the northern Atlantic coast south to the Carolinas. Marine, estuarine and freshwater ecosystems with salinities ranging from 5 to 18 percent have been known to support white perch (Mansueti 1964). The species is semianadromous, making spawning runs up coastal streams. It commonly becomes completely landlocked in ponds and reservoirs of its native range where it spawns successfully. This species has been known as a game fish to generations of New England fishermen, but when stocked in landlocked waters …

Effluent Travel Estimates From Ships Anchored In Chesapeake Bay : A Report To The Virginia State Water Control Board, C. S. Fang, C. S. Welch, T. J. Brooks

Reports

As the world demand for coal has increased, the number of colliers arriving at Hampton Roads, Virginia, to load coal has exceeded the ability of the port to supply the demand. As a result, a substantial backlog of ships waiting to load coal is presently taxing the anchorage capacity of the harbor. A recent estimate is that 130 ships are waiting about 38 days each for their turn at the loading factl1t1es. In addition to the anchorages tn Hampton Roads and the lower James River, new anchorages have been opened to accomodate these ships, one on the southern side of …

Energy Siting In Utah: A Programming Model, Donald L. Snyder, John E. Keith, Terrence F. Glover, Gene L. Wooldridge

Reports

Using a conceptual model of a multiple-product firm, the necessary conditions for an optimal input and output allocation were determined for a region constrained by resource availabilities and/or policy constraints. A linear programming model was developed to deteremine the optimal allocation of water between agricultural and coal-fired electrical generating entities as well as the trade offs which could occur if electrical generation were increased. Other areas of potential trade offs such as coal source restrictions and air quality regualtions were also examined. Coal mining and transportation costs were included as were SO2, Nox, and particulate emission rates on a coal …

Physical And Chemical Limnology Of Lake Mcconaughy, Melvin W. Taylor, Kit M. Hams

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

Lake McConaughy is an important fishery resource of the state of Nebraska. The estimated fishing pressure in 1975 as determined from a postal creel census was 175,872 angler days (Morris 1977). This estimate is inflated compared to an on-site creel census conducted in 1977-78 which showed a total of 69,500 fishing trips annually (Madsen 1980). Not all fishermen were contacted so this estimate is undoubtedly too low. Regardless of which figure is accepted, the reservoir provides many man-days of fishing opportunity. Conservation and management of the fishery resource is necessary to maintain and/or improve its quality,

Wind Erosion In The Jerramungup Area 1980-1981, Bryan J. Goddard, M G. Humphry, D J. Carter

Resource management technical reports

An investigation of the wind erosion problem at Jerramungup was conducted by on-farm survey and Landsat interpretation from September to November 1981. Sandblasting and wind erosion were estimated to have seriousloy affected some 44,000 ha in 1980 and over 64,000 ha in 1981. The 1981 damage estimate is conservative, because a much greater area of pasture land was affected by erosion in May-July but achieved vegetative cover by later winter.

The Consequences Of Nutrient Enrichment In Estuaries, Bruce J. Neilson

Reports

A "paper study" was conducted to determine the consequences of nutrient enrichment in an estuary. First, a classification scheme was developed to assign- a "Level of Nutrient Enrichment" to a water body based on concentrations of Total Phosphorus and Total Nitrogen. The impacts of nutrient enrichment on the various uses of estuaries there were described and assessed. Finally, "safe" nutrient levels for Chesapeake Bay and its tributaries were recommended.

Role Of Gulf Stream Frontal Eddies In Forming Phytoplankton Patches On The Outer Southeastern Shelf, James A. Yoder, Larry P. Atkinson, Thomas N. Lee, Hongsuk H. Kim, Charles R. Mcclain

CCPO Publications

Continuous surface mapping of temperature, salinity, and chlorophyll along a 300-km segment of the Gulf Stream cyclonic front defined the spatial scales of a large diatom patch that persisted throughout a 10-day study. The patch was localized in the upwelled cold core of a Gulf Stream frontal eddy centered over the 200-m isobaths off Jacksonville, Florida, in April 1979. The µ g liter^-1 surface chlorophyll isopleth enclosed an area >1,000km² with an alongshore dimension of 130km. Surface chlorophyll exceeded 5µg liter^-1 within the upwelled cold core of the eddy, 10-100X higher than concentrations in Gulf Stream or …

The Potential For Groundwater Contamination Along Basin Margins In The Arid West: Alluvial Fans And Lake Features, Calvin G. Clyde, Robert Q. Oaks, Peter T. Kolesar, Edward P. Fisk

Reports

Many towns of the arid west were built upon alluvial fans and upon sites underlain by Pleistocene lake deposits. The objective of this study was to assess the potential impact of these activities of man upon groundwater quality within these geological features. Emphasis was placed on shallow groundwater quality after it was determined that deep groundwater is rarely contaminated at such sites. A reconnaissance of Utah and Nevada was made and four sites underlain by alluvial fans (Willard, Manti, Elsinore, and Spring City) and four sites underlain by lake shore deposits (Hyde Park, Fielding, Providence and Richmond) were selected in …

Water Quality In Pleasant Valley, Utah, Calvin G. Clyde, Dennis B. George, Kun Mo Lee, Phil Pucel, William Hay

Reports

Pollution of shallow groundwater due to wastewater disposal in Pleasant Valley, Utah, was investigated from October 1979 through August 1980. Water samples were collected from 23 wells and 5 stream sampling sites. Water quality analysis revealed pollution at several sites. Groundwater pollution caused by man’s activities in the area was observed in Bolotas and Scofield Campsite subdivisions. Severe shallow groundwater pollution measured in wells which were located in south and north profiles of the town of Scofield, Utah, could have originated from the municipal waste disposal practice in the town. Natural phenomena, however, such as pyrite oxidation, could possible have …

Design Considerations In The Use Of Glauber Salt For Energy Storage, Duane G. Chadwick, Kim H. Sherwood

Reports

Various design concepts for the utilization of the latent heat of Glauber salt at temperatues between 25 degrees C and 50 degrees C were studied. Consideration was given to system economics and what particular heat storage system if perfected would be most cost effective. The problems of limited crystal size and heat transfer into and out of salt crystals is discussed. Crystal size is affected by the degree of agitation the salt solution experiences during the salt cooling process. Consequently, crystal size was moderated in a favorable way by introducing air bubbles at the bottom of the salt container. As …
