Fungal Control Methods, Diets And Water Temperatures Used To Culture Paddlefish, Polydon Spathula, Ronald L. Brandt

Electronic Theses and Dissertations

Studies were conducted at Gavins Point National Fish Hatchery, South Dakota, in 1976 and 1977, to evaluate the effects of diet and water temperature on growth and survival of paddlefish, Polyodon spathula, young, and the effects that fungicides have on hatching success and fry survival. The W-7 cool water diet was fed hourly and three times daily while the Liv commercial diet was fed hourly to paddlefish young for 40 days after swim-up. Average survival rate and total length of paddlefish fed W-7 hourly were 16.0% and 30 mm, those fed W-7 three times daily were 10.0% and 23 mm, …

Evaluation Of The Long Term Effects Of Irrigation With Wastewater, James H. Reynolds, M. O. Braun, W. F. Campbell, R. W. Miller, L. R. Anderson

Reports

Introduction: Background: The application of municipal wastewater to the land or using the soil mantle as a wastewater treatment system has been practiced for many years. The history of land application dates back to ancient Athens. Sewage farming or the transportation of wastewater to rural areas for irrigation and disposal was practiced in Eurpose as early as 1559. The practice became fairly widespread in England, France, Germany, Poland, Austria, and the United States during the late 1800's [

The Biology Of Coprinus Radians, Ozonium, Oidium, And Their Interrelationships, Thomas J. Fahey

All-Inclusive List of Electronic Theses and Dissertations

The pleomorphism of Coprinus radians was studied. The three distinct growth forms--sporophore, oidial stage, and ozonium stage--were examined in relation to ultrastructure, morphology and development. Scanning and transmission electron microscopy are correlated with photomicrographs of developmental stages. Development of the oidia and of the sporophore are of particular interest. The multinucleate oidia develop quite differently from oidia as generally described for Basidiomycete imperfect stages. Development of the oidia of this Coprinus is holoblastic and sympodial. The mushroom primordia are differentiated internally into gill, cap, and stipe hyphae while only l-2mm in diameter. At this stage they look superficially like sclerotial …

Coyote-Food Base Relationships In Jackson Hole, Wyoming, John L. Weaver

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I measured three variables of coyote-food base relationships in Jackson Hole, Wyoming, during the period July, 1973, to July, 1975. Field work provided estimates of relative coyote and prey abundance as well as observations on coyote feeding behavior during winter. Laboratory analysis of 1,500 coyote scats revealed feeding patterns while feeding trials with captive coyotes allowed refinement in interpretation of scat analysis.

Deer mice and chipmunks comprised most of the rodent biomass captured in traps in the fall, while ground squirrels accounted for much of the rodent biomass in the spring. Field voles declined from 1973 to 1974 throughout much …

Biological Manipulation Of Blackbrush (Coleogyne Ramosissima Torr.) By Browsing With Goats, Frederick D. Provenza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to provide data on responses of Angora goats and blackbrush (Coleogyne ramosissima) to a biological manipulation program. Blackbrush utilization levels averaged 30, 16, and 6 percent (545, 367, and 147 kg per hectare) for the heavily, moderately, and lightly browsed pastures, respectively; removal rates of 77, 38, and 19 percent (1164, 582, and 291 kg per hectare) were projected.

Statistically significant differences in body weight loss (P=0.052) were noted for goats browsing in different replications. Goats lost an average of 14 and 19 percent of body weight in replications one and two, …

Progress In Pine Vole Ecological Research And Its Relevance To Damage Control, R. L. Kirkpatrick, R. E. Noffsinger

Eastern Pine and Meadow Vole Symposia

LaVoie and Tietjen (1971) pointed to the "paucity of quantitative data concerning vital phases of the life history of the pine vole" as one possible reason for our lack of progress in controlling pine vole damage. They suggested that pine voles do not seem to be readily adaptable to a wide range of habitat types and conditions and that this lack of adaptive ability might be exploited in their control by manipulation of limiting factors in their habitat. They also suggested a balanced program of research which would include studies of vole populations, their habits and their habitats as well …

Some Basics Of Marron Production, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

marron are native to the South-West of Western Australia, and are keenly sought by inland fisher-men. However, supplies do not equal the apparent demand.

One solution is to cultivate marron in farm dams, or more intensively as a commercial enterprise.

This article suggests a few guidelines for marron production.

Estimate Of Production By A Population Of Fathead Minnows, Pimpephales Promelas, In A South Dakota Prairie Wetland, Ronald D. Payer

Electronic Theses and Dissertations

Estimates of production and population densities were obtained for an autochthonous population of fathead minnows, Pimephales promelas Rafinesque, in a South Dakota prairie wetland. The study was conducted from May to September of 1976. Population estimates were obtained using a Schnabel-type mark and recapture model. Fish were marked either by fin clipping or granular fluorescent pigments driven into the dermal tissue. Production estimates were derived both arithmetically and graphically. The estimated population of adult fathead minnows declined from 194 in May and June to 26 in July. Production by adults was estimated at 0.10 kg, or 0.0007 gm/m²/yr. The population …

Digestibility Of Common Forage Plants And Energetic Requirements Of The Black-Tailed Prairie Dog, Maureen A. Beckstead

Electronic Theses and Dissertations

Black-tailed prairie dogs (Cynomys ludovicianus) assimilated 51.5 percent of the wheatgrass (Agropyron intermedium) they consumed; thus, they would have to consume 0.148 kcal · g-1 · day-l in order to obtain the 0.076 kcal · g-1 · day-1 they would require to maintain their weight. Prairie dogs assimilated 31.5 percent of the buffalograss/blue grama mixture (Buchloe dactyloides/Bouteloua gracilis) they were fed. They would have to consume 0.229 kcal · g-1 · day-1 of this forage to assimilate 0.072 kcal · g-1 · day-1 and maintain their weight. The proximate composition of forages fed in feeding trials was similar to that …

Biology Of The Porcupine (Erethizon Dorsatum) In Northwestern South Dakota, Judith Johnson

Electronic Theses and Dissertations

The summer home ranges, food habits, cover preferences, population dynamics, metabolic rates, growth rates, and taxonomic characteristics were determined for porcupines (Erethizon dorsatum) in northwestern South Dakota. The summer home ranges were 158.2 ha for adult females, 90.4 ha for juveniles, and 57.9 ha for adult males. The population was 34 percent adult males, 16 percent juvenile males, 34 percent adult females, and 15 percent juvenile females. The preferred daytime cover choice was silver buffaloberry (Shepherdia argentea), followed by snowberry (Symphoricarpos occidentalis), earth dens, forbs, and low brush. Shrubs were the most important item in the diet, then trees, forbs, …

Selection Of Toxic Poultry Pellets From Cattle Rations By Starlings, Richard R. West, Jerome F. Besser

Bird Control Seminars Proceedings

Populations of wintering Starlings(sturnus vulgaris) causing problems at cattle feedlots have been effectively reduced by broadcasting pellet baits treated with 1 % DRC-1339 (3- chloro-p-toluidine hydrochloride) in their feeding areas (Besser, et al., 1967; West, et al., 1967; West, 1968). Each 1% DRC-1339 pellet (averaging 70 mg in weight) contains an amount of toxicant sufficient to be lethal to a starling (DeCino, et al., 1966). Besser, et al. (1968) estimated that starlings at cattle feedlots take about half their diet from the troughs. However, during severe winter weather, many Starlings take most of their food from troughs, and some appear …

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 …

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 …

Contamination Of Forest Ecosystems By Sodium Fluoroacetate (Compound 1080)*, J.A. Peters

Vertebrate Pest Conference Proceedings: 7th (1976)

Predictive and conceptual models are used to examine the contamination, toxicology, and residues of sodium fluoroacetate (Compound 1080) in relation to its application in vertebrate pest control programs on forest and pastoral lands.

As a pesticide, the toxin appears to be neither mobile nor persistent. Exceedingly slender opportunities exist therefore for significant contamination of susceptible components of the environment.

Control Methods For Nuisance Beaver In The Southeastern United States, Edward P. Hill

Vertebrate Pest Conference Proceedings: 7th (1976)

Strychnine alkaloid baits were consumed by both captive and wild beaver without any apparent hesitation. An approximate minimal acute lethal dose of sodium monofluoro-acetate to beaver of mixed ages and sex was 0.202 mg/kg. Trapping beaver on four study area watersheds in Alabama with No. 330 conibear traps for approximately two weeks in winter during two successive years essentially eliminated beaver. Older individuals were trapped the first year, maturing juveniles and the remaining few adults were trapped the second year, and there was very little reproduction between the trapping periods. Trapping, with its recreational appeal, and income and food potential …

1976 Sunflower-Safflower Irrigated Variety Trial 1976-1977, G J. Parlevliet

Experimental Summaries - Plant Research

In 1975/76 two varieties of sunflower, Hysun 10 and Hysun 20, as well as Safflower (Gila) were grown in a large alternative crop demonstration. Results were sufficiently good to warrant more and closer examination. This led to the present variety trial using varieties suggested by Mr. M. Poole. The aim was to evaluate six sunflower varieties and one safflower. The work was carried out in the light of reduced profitability of peas, beans and some fruit crops. This results in a number of growers having irrigation water and equipment under-employed. Other farmers are after a crop which will give them …

Environmental protection provided by control facilities requires basic knowledge of the physical and chemical properties of feedlot runoff. This bulletin summarizes studies of physical and chemical properties of beef cattle feedlot runoff completed from August, 1968 through December, 1972.

Biochrome Analysis As A Method For Assessing Phytoplankton Dynamics Phase Ii, 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, orthophosphate-P and silicates are described …
