Social Behavior And Activity Patterns Of Meadow Voles In Relation To Seasonal Change And Snow Cover, Ronald J. Brooks, A. Bruce Webster
Social Behavior And Activity Patterns Of Meadow Voles In Relation To Seasonal Change And Snow Cover, Ronald J. Brooks, A. Bruce Webster
Eastern Pine and Meadow Vole Symposia
Activity and social behavior of free-ranging meadow voles (Microtus pennsylvanicus) were examined in summer, fall, and winter using capture-recapture and radiotelemetry. The composition of our study population changed from predominantly reproductively-active (RA) voles in summer and fall to entirely non-reproductively-active (NR) voles in winter. RA males had larger activity areas than RA females. Activity areas of RA females did not overlap with those of other RA females, but activity areas of RA males overlapped extensively with those of both RA males and RA females. However, any contact among RA voles was rare, unless females were estrous. NR voles …

U.S. Army Corps Of Engineers Public Interest Review: An Evaluation Of Implementation Effectiveness, Sharon Kelberg
U.S. Army Corps Of Engineers Public Interest Review: An Evaluation Of Implementation Effectiveness, Sharon Kelberg
Marine Affairs Theses and Major Papers
The U.S. Army Corps of Engineers is authorized to permit or deny dredge and fill activities in the nation's coastal and wetland regions. Originally, responsible only for the maintenance of navigation, the Corps considered only navigational requirements in decisions to grant or deny permits. Now, however, the Corps must demonstrate, that the "public interest" is served as well. This study examines the scope of the public interest and attempts to evaluate the effectiveness of the program in a particularly controversial project. The initial phase provides evaluation criteria necessary to analyze the application of the public interest review. The second phase …

Auctions As An Alternate Method Of Selling Fish In New England, Martin J. Vincent
Auctions As An Alternate Method Of Selling Fish In New England, Martin J. Vincent
Marine Affairs Theses and Major Papers
Selling fish at the landings stage by auction, as opposed to the current practices of selling to middlemen and through cooperatives, has been proposed by several authors. They suggest that fishermen would receive higher prices and that auction competition would improve fish quality.The aim of this study was to compile the rules and procedures of existing fish auctions, and to explore their effect on price formation. This would provide a basis for any who wished to determine the applicability of fish auctions in particular ports. While the findings are relevant to all fish auctions, special emphasis was placed on the …

All U.S. Government Documents (Utah Regional Depository)
North Horn Mountain is part of a deeply dissected plateau in central Utah which is characterized by deep, arrow, steep-walled canyons with local relief of more that 1,000 feet. Geologic units exposed in the North Hort Mountain area range in age from Late Cretaceous to Holocene and contain two mineable seams of Cretaceous coal. The area is in the drainage basin of the San Rafael River, in the Colorado River Basin. Runoff from the mountain is ephemeral. This runoff to the San Rafael River sis by way of Cottonwood and Ferron Creeks and represents less than 10 percent of their …
Trace Metal Pollution In Narragansett Bay: A Case Study Of The Rhode Island Quahog Fishery, Scott W. Horsley
Trace Metal Pollution In Narragansett Bay: A Case Study Of The Rhode Island Quahog Fishery, Scott W. Horsley
Marine Affairs Theses and Major Papers
This paper was written with two objectives in mind: to provide information relevant to the protection of the quahog fishery and the protection of human health. Both are threatened as hundreds of millions of gallons of industrial effluents and sewage treatment plant discharges enter Narragansett Bay daily. The implications of trace metal pollution with respect to the quahog fishery have received little attention to date. The purpose of this paper is to assemble scientific, legal, and socioeconomic information in a fashion which will direct future research and management attempts in an effective manner.

A Survey And Evaluation Of Shallow Groundwater Contamination Hazards In The State Of Utah, Edward P. Fisk, Calvin G. Clyde
Reports
A survey was made to appraise current man-made contamination of shallow groundwater in Utah. Very little has been published on the subject, and most of the information was obtained by personal observation and through interviews of individuals concerned with water quality protection in Utah. After presenting the relevant physiographic, geologic, and hydrologic characteristics of the various regions of Utah and discussing how these relate to groundwater contamination in general, representative groundwater quality hazards in 32 sites or regions in Utah are presented. A very wide range of hazards to groundwater quality was found to exist. These cases cover the range …

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 …

The Physical And Chemical Limnology Of Lake Mcconaughy With Reference To Fisheries Management, Melvin W. Taylor, Kit M. Hams
The Physical And Chemical Limnology Of Lake Mcconaughy With Reference To Fisheries Management, Melvin W. Taylor, Kit M. Hams
Nebraska Game and Parks Commission: Publications
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,
An important factor in …

Technological Status And Legal/Regulatory Aspects Of Low-Head Hydroelectric Power Development In Missouri, Charles Darwin Morris, Gordon E. Weiss
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
This paper will present the broad overview of hardware availability, systems design and 1egal/regulatory constraints presently connected with the development of small hydropower systems in water rich areas such as southeastern Missouri. There is great interest being evidenced today on the part of major federal agencies and some power companies in regard to the feasibility of utilization of the power potential inherent in small streams. The topic is of particular interest to Missourians because of the vast number of small streams present in Missouri.
