Measuring The Intangible Values Of Natural Streams, Part I, John A. Dearinger, George M. Woolwine

KWRRI Research Reports

The purpose of this study was to apply the "uniqueness concept" to the quantification of the intangible values of natural streams. The methodology is based on procedures developed by Luna B. Leopold and Maria O. Marchand of the U.S. Geological Survey. It involves the evaluation of a set of characteristics or factors for selected stream sites. Each factor is rated for each site on a numerical scale indicative of the range of possible "values" for that factor. An "uniqueness ratio" (the reciprocal of the number of stream sites sharing a given category rating) is then computed for each stream for …

Recent Sediments Of Humboldt Bay, Eureka, California, Robert Wayne Thompson

Special Collections Archived Publications

Humboldt Bay is a coastal lagoon, 14 mi. long and a maximum of 4 mi. wide. The bay has three distinct segments, South, Entrance, and Arcata Bays, each of which occupies the seaward end of one or more stream valleys cut into Plio- Pleistocene paralic sediments. The segments are linked by narrow tidal channels which are bounded by a barrier spit on the west and by high valley interfluves on the east. Climate of the area is rainy temperate . Tides are of the mixed type with a mean range of 6.5 ft.

Movements And Habitat Use By Hen Pheasants During Brood Rearing, Lynn E. Hanson

Electronic Theses and Dissertations

Land-use patterns characteristic of prime pheasant range in the Great Plains and prairie region have 50-75 percent of the land under cultivation according to Kimball et. al. (1956). Farmland is pheasant habitat, and the production of pheasants is therefore greatly influenced by farming practices. Considerable research has been done on rates of pheasant production, nest success, and cover preferences for nesting. However, little information has been obtained on movements and cover preferences for brood rearing. Most studies of the type of cover utilized by pheasant broods have been based on roadside and random field observations. Kozicky and Hendrickson (1951) carried …

Interpretive Potential Of South Dakota Wetlands, Douglas C. Harr

Electronic Theses and Dissertations

A study was initiated to devise a method for selecting prairie wetlands on which nature interpretation areas could be established. An evaluation form was designed to systematically identify areas of good potential and 64 prairie wetlands were evaluated. Twenty-two percent of the evaluated marshes were found to rank “excellent”: the method of evaluation was determined successful. A survey was initiated to determine visitor preferences for interpretive methods and facilities at an existing wildlife-interpretive trail. Seventy-nine percent of the visitors indicated preference for a self-guiding interpretive trail. Maps and pictures used in conjunction with self-guiding signs were deemed important. Ninety-one percent …

Micronutrients And Biological Patterns In Lake Mead, Hasan K. Qashu, Lorne G. Everett, J. S. Carlson, Bureau Of Reclamation

Publications (WR)

Progressive increases in concentration of dissolved solids in the Colorado River water from Lake Powell to Imperial Dam seem to alter plankton dynamics and biological productivity of the river. Also, changes in biological productivity and micronutrients concentrations occur within the same reservoir. Development of a digital simulation model to predict micronutrients concentrations and biological productivity is necessary for diagnosing changes in plankton population and effluent-carrying capacity of the system.

The objectives of the study are: (1) to determine trace metal balance at different locations in Lake Mead, (2) to measure biological productivity and conduct plankton population counts at each sampling …

Effects Of Chick Stimuli And Dieldrin On Adoptive Behavior Of Penned Hen Pheasants, K. L. Cool

Electronic Theses and Dissertations

Studies to determine the effect of chick stimuli and dieldrin on adoptive behavior of penned hen pheasants were conducted in 1969 and 1970. Results indicated that whether caged hens saw or heard chicks had no effect on adoption or killing of chicks. Hens receiving sound stimuli and sight-and-sound stimuli from chicks responded similarly to hens receiving no stimuli. Sub-lethal doses of dieldrin also had no effect on chick adoption under the conditions of this study. Results demonstrated that non-incubating pheasant hens will adopt and brood orphan chicks. During the 2 years of the study, respectively, 37 and 49 percent of …

Food Habits Of Black Crappies, White Crappies, Yellow Perch And White Suckers In A Small Impoundment In Northeastern South Dakota, Dennis Unkenholz

Electronic Theses and Dissertations

Crustaceans, aquatic insects and fish were the most important food items found in stomach samples. Black crappies depended on zooplankton and aquatic insects as their major food source as they occurred in all samples and were major food items in 70 percent and 40 percent respectively. Insects, zooplankton and fish were the major food items of white crappies. Insects were the dominant forage present in 54 percent of the samples while zooplankton and fish were dominant in 36 percent and 21 percent of the samples respectively. Perch relied on crayfish, fish and aquatic insects as their major food source. Aquatic …

Population Dynamics Of The Mourning Dove In South Dakota, Leslie A. Rice

Electronic Theses and Dissertations

Mourning dove bandings in South Dakota totaled 44,842 from 1917 through 1970. Adult bandings totaled 44.4 percent of all bandings while immatures, juveniles, locals, and unknown age were 41.3, 0.8, 12.8, and 0.7 percent, respectively. Recoveries totaled 2.8 percent of the banded population, 2.5 percent from hunting and 0.5 percent from non-hunting. Annual mortality estimates of local (nestling) bandings from 1956-61 were between 54.4 and 64.5 percent. Subsequent adult mortality from local bandings was between 51.0 and 52.4 percent. Mean annuals mortality estimates of flying doves banded from 1964-69 were calculated using composite dynamic, composite time-specific, relative recovery rate, a …

Food Habits Of Deer In The Southern Black Hills As Determined By The Point Technique, Theron E. Schenck

Electronic Theses and Dissertations

White-tailed (Odocoileus virginianus) and mule deer (Odocoileus hemionius) were collected in 1968 and 1969 for a study of food habits. Rumen contents were analyzed by use of the point-analysis technique and weights. This is the first food habits study from the southern Black Hills and is necessary for proper deer management. To evaluate the suitability of the point technique for Black Hills vegetation, an artificial population was constructed from known weights of a forb, (Achillea lanulosa), grass (Oryzopsis asperfoliz), rose (Rosa sp.), kinnikinnick (Arctostaphylos uva-ursi), and ponderosa pine (Pinus ponderosa). Each population was tested with 100-point trails and 200-point trials. …

A Clinico-Pathologic Study Of Botulism In Ring-Necked Pheasants, Hazel J. Shave

Electronic Theses and Dissertations

Toxins were produced from 6 strains of Cl. Botulinum, 2 of which killed pheasants. Inoculated birds were observed and a description of the progression of signs of the disease is given. Juvenile pheasants were inoculated with Types A and C toxin intramuscularly and were given the toxin orally. These birds were observed and their clinical signs noted. Adult pheasants were inoculated with toxoid prepared from type C toxin and commercial toxoid; injections were repeated in 21 days. Fourteen days following the final injection, the birds were challenged with toxin. Those protected with toxoid survived, while those receiving saline succumbed. Gross …

Macroscopic Benthos Populations And Taxonomy Of The Family Chironomidae In Lake Poinsett, South Dakota, Stephen B. Smith

Electronic Theses and Dissertations

Benthos samples were collected in Lake Poinsett, a highly eutrophic eastern South Dakota lake, from March 1970 through February 1971. The lake bottom was divided into three substrate types (sand, sand-sapropel mixture and sapropel) and the percent of each substrate type was calculated. Nineteen macroscopic genera were taken from ten sampling stations located throughout the lake. Descriptions are presented for organisms in this group. Diversity of organisms was greatest in the sand substrates, in that all 19 genera were collected. Chironomus spp. (Chironomus plomosus, Chironomus attenuates and six unidentified species) was the most abundant group of organisms and occurred most …
