Lungworm Infections, Reproduction And Summer Habitat Use Of Bighorn Sheep In Custer State Park, South Dakota, Gary C. Brundige Jan 1985

Lungworm Infections, Reproduction And Summer Habitat Use Of Bighorn Sheep In Custer State Park, South Dakota, Gary C. Brundige

Electronic Theses and Dissertations

Bighorn sheep (Ovis canadensis) were once indigenous to the Black Hills and Badlands of South Dakota. When European settlers moved into this region during the late 1800' s, market hunting, loss of habitat, and introduction of animal diseases and parasites caused the subspecies of the region, the Audubon's bighorn sheep (O. c. auduboni), to become extinct by 1916 (Buechner 1960). To reestablish bighorn sheep in the Black Hills, 8 Rocky Mountain bighorn sheep (O. c. canadensis) were introduced into the former range of the Audubon's sheep in 1922. Finding the habitat to be very suitable, this small population increased to …


Efficiency Of Two Black-Tailed Prairie Dog Rodenticides And Their Impacts On Non-Target Bird Species, Anthony Dean Apa Jan 1985

Efficiency Of Two Black-Tailed Prairie Dog Rodenticides And Their Impacts On Non-Target Bird Species, Anthony Dean Apa

Electronic Theses and Dissertations

In 1983 zinc phosphide, strychnine with prebait, and strychnine without prebait were applied to black-tailed prairie dog (Cynomys ludovicianus) colonies in west-central South Dakota. Short-term (4 days later) and long-term (1 year later) poison efficiency and impact (short-term and long-term) on horned larks (Eromophila alpestrus) and other seed-eating birds of the prairie dog colonies were evaluated. Prairie dog burrow densities ranged from 54-187 burrows/ha with an average burrow density of 114 ±8 (± SE) burrows/ha. Rodenticide short-term control reduced active burrows by 95% with zinc phosphide, 42% with only strychnine, and 78% with prebaited strychnine. More zinc phosphide was consumed …


Distribution, Temperature Selection, And Gonadal Development Of Fishes In A Power Plant Cooling Reservoir, Henry R. Maddux Jan 1985

Distribution, Temperature Selection, And Gonadal Development Of Fishes In A Power Plant Cooling Reservoir, Henry R. Maddux

Electronic Theses and Dissertations

The distribution, temperature selection, and gonadal development of fishes in the Big Stone Power Plant cooling reservoir were examined from July 1982 through July 1983. A total of 46.8% of the fishes captured during this study were from the discharge area, while 31.8% and 21.4% of the fish occurred in the mixing and intake areas, respectively. The mean water temperature occupied by common carp (Cyprinus carpio) ranged from 7.5 C in February to 31.2 C in August. Black bullheads (Ictalurus melas) were generally benthic and captured in the cooler water. The mean water temperature occupied by black bullheads ranged from …


The Taarblin Experience : A Planned Approach To Soil Conservation, Greg Astbury, Owner/Manager Of Taarblin, Tim Negus Jan 1985

The Taarblin Experience : A Planned Approach To Soil Conservation, Greg Astbury, Owner/Manager Of Taarblin, Tim Negus

Bulletins 4000 -

Many farms in Western Australia were cleared and developed before there was a full and clear understanding of the effects of bush clearing - that is salinization of soil and water supplies, wind and water erosion, waterlogging and soil structure decline. The productive capacity and inherent problems of the different soil types was also largely unknown.

Modern-day Conservation Farm Planning aims to provide a blue-print for the redevelopment of properties to ensure long term soil fertility, to prevent soil erosion and degradation by waterlogging and salinity. It also provides for a spread of reliable stock watering points and more efficient …

Fisheries Report No 71 - An Investigation Of The Mortality Of The Pearl Oyster, Pinctada Maxima, In Western Australia, Rand Dybdahl, David A. Pass Jan 1985

Fisheries Report No 71 - An Investigation Of The Mortality Of The Pearl Oyster, Pinctada Maxima, In Western Australia, Rand Dybdahl, David A. Pass

Fisheries Research Reports

A three year investigation into the cause of abnormally high mortality rates of the pearl oyster, Pinctada maxima, on the cultured pearl industry's lease sites in the North West of Western Australia was completed on 30 June 71983. The objective of this study was to determine environmental, physiological and pathological factors predisposing farm oysters to excessive Levels of mortality and, if possible, make recommendations to alleviate this problem.

As mass mortalities may have complex causes, complementary field and laboratory studies were instigated. The culture industry's method of collection, transportation and farm husbandry were examined. Environmental parameters were monitored. Various empirical …

A Proposal To Fertilize The Overton Arm And Gregg Basin Areas Of Lake Mead, Larry J. Paulson Nov 1984

A Proposal To Fertilize The Overton Arm And Gregg Basin Areas Of Lake Mead, Larry J. Paulson

Publications (WR)

Several limnological studies have been conducted in Lake Mead during the past decade. The recent studies clearly show that most of Lake Mead is deficient in nutrients, especially phosphorus, and very low in productivity. The reservoir-wide average total phosphorus concentration for 1981 - 1982 was only 9 mg/m3. This is below levels found In most oligotrophic lakes and reservoirs. Algal biomass, as measured by chlorophyll-a, averaged only 1.5 mg/m3. That also places Lake Mead in the oligotrophic range. Transparency, as measured by a Secchi disc, averaged 9-5 m in Lake Mead during 1981-1982. That far exceeds …

An Evaluation Of Naturally Occurring Populations Of Magnolia Tripetala L. In Indiana, Kemuel S. Badger Aug 1984

An Evaluation Of Naturally Occurring Populations Of Magnolia Tripetala L. In Indiana, Kemuel S. Badger

All-Inclusive List of Electronic Theses and Dissertations

Magnolia tripetala L. occurs in Indiana as a disjunct from the Appalachian mountains populations. Currently, the known distribution of ~· tripetala in Indiana is confined to seven sites in Crawford County. The current status of ~· tripetala and the surrounding plant community was evaluated to aid in the future study, protection and management of this species, which is endangered in Indiana. Systematic random sampling of the tree stratum was done with belt transects. The sapling and seeding strata were sampled with subplots, placed along the belt transects. Permanent plots were established to enable future monitoring of what is currently prime …
