The Effect Of Human Disturbance On Vegetation At The Wehr Nature Center In Whitnall Park, Mariette M. Nowak Oct 1976

The Effect Of Human Disturbance On Vegetation At The Wehr Nature Center In Whitnall Park, Mariette M. Nowak

Field Station Bulletins

During 1975 and 1976, I studied (Nowak, 1976) two woodlands at the Wehr Nature Center in WhitnaLl Park, Milwaukee County (Figure 1). My purpose was to document the vegetational changes brought about by human disturbance. The Wehr Woods, adjacent to the Wehr Nature Center Building, had been lumbered and grazed; while the woods along College Avenue is subjected to seasonal flooding, a result of road construction which had altered the drainage pattern. In each woodland, a disturbed portion was compared with an adjacent, relatively undisturbed area. The heavily lumbered and grazed portion of the Wehr woods will be referred to ...


Analysis Of Four Common Play Patterns In Juvenile Thirteen-Lined Ground Squirrels (Spermophilus Tridecemlineatus), Mary Melville Oct 1976

Analysis Of Four Common Play Patterns In Juvenile Thirteen-Lined Ground Squirrels (Spermophilus Tridecemlineatus), Mary Melville

Field Station Bulletins

Young mammals spend a considerable amount of time engaged in activities which are called "play". The ethological literature contains much controversy concerning the definition and adaptive significance of play. Fagen (1974) characterizes playas active, oriented behavior with a highly variable structure, which apparently lacks immediate purpose, and which is often accompanied by specific signal patterns. He also notes that in playful behavior the adult sequences of behavior break down. Behavioral components such as threats, grooming and sexual posturing are performed in novel and rapidly changing sequences that would be nonadaptive in the serious contexts of adult life. Play in young ...


A Study Of A Population Of The Slender Glass Lizard In Waushara Co., Wisconsin, Thomas A. Pleyte Oct 1976

A Study Of A Population Of The Slender Glass Lizard In Waushara Co., Wisconsin, Thomas A. Pleyte

Field Station Bulletins

The slender glass lizard (Ophisaurus attenuatus), a limbless member of the family Anguinidae, is one of the few lizards found in the state of Wisconsin. Records indicate that it is found locally in several sandy areas in the southern half of the state but little was known about its abundance in any of these areas before the present study was conducted in 1973 and 1974.

Dairy Cattle Breeding: Contributions Of Research On Field Data, L. Dale Van Vleck Sep 1976

Dairy Cattle Breeding: Contributions Of Research On Field Data, L. Dale Van Vleck

Faculty Papers and Publications in Animal Science

Papers about dairy cattle breeding published in the Journal of Dairy Science from 1960 through 1975 were categorized according to whether the data came from institutional herds or from field collection and also according to whether the research was done with support of a regional project. Most project papers involved institutional data. The vast majority of non-project papers made use of field data. Nearly all papers classified as theoretical were also associated with field data or field recommendations. The major impact of breeding research projects with field data has been from improved genetic evaluation for production and from development of ...

Effects Of Female Sex Hormones And Dietary Magnesium Levels In Sheep, Kenny S. Marbury Aug 1976

Effects Of Female Sex Hormones And Dietary Magnesium Levels In Sheep, Kenny S. Marbury

Masters Theses

The major objectives of this study were to evaluate (a) the effects of diet on magnesium, calcium and potassium metabolism in yearling wethers and (b) the effects of progesterone, estradiol and diethylstilbestrol (DES) on the metabolism of the minerals.

A two by two factorial design was selected whereby twelve yearling crossbred wether lambs were divided into four groups of three. One group was fed a basal diet plus magnesium along with hormones, one group was fed a basal diet plus magnesium without hormones, one group was fed a magnesium-deficient diet along with hormones, and one group was fed a magnesium-deficient ...


Flight Of The Sea Ducks, Paul A. Johnsgard Aug 1976

Flight Of The Sea Ducks, Paul A. Johnsgard

Papers in Ornithology

Their migration routes have been charted. Their breeding biology is known. Their eggs meat and feathers have long been used by man. But eiders at sea remain an enigma.

Nesting in colonies that can number hundreds of birds, the eiders are among the most conspicuous of tundra-breeding birds. Although female eiders are a study in grays and browns that match the arctic tundra, the males are most boldly patterned in black and white, with striking green head colors. When the nesting season ends, the birds disperse over the vastnesses of the northern oceans, out of range of most human observers ...

Comparison Of Methods Of Selection To Increase Yearling Weight Of Beef Cattle And Assessment Of Influence Of Sire Differences On Estimates Of Repeatability Of Cow Productivity, Thomas Bruce Turner

Doctoral Dissertations

The objectives of this study were: (1) to make a theoretical comparison of progress expected by selecting for a single trait with progress expected by selection based on an index including two traits and (2) to compare estimates of repeatability of cow productivity when the effect of sire is removed from the data and when it is not.

Data were collected over a period of seven years from 581 bull calves and 552 heifer calves from the purebred Angus herd at The University of Tennessee Plateau Experiment Station, Crossville.

Variables recorded at weaning (approximately seven and one-half months of age ...


Nutritional Efficiency Of Angus Cow-Calf Units, Dennis Owen Onks Aug 1976

Nutritional Efficiency Of Angus Cow-Calf Units, Dennis Owen Onks

Doctoral Dissertations

Angus cow-calf pairs were individually fed over a five-year period. Data from 62 mature cows and 114 calves were obtained. Cows varied in initial weight and production potential. Cows were fed grass silage, ad libitum, throughout gestation and lactation. Calves were fed a complete finishing and growing ration post weaning. Efficiency of cow-calf units was defined as the ratio of the yearly TDN intake of the cow plus the pre-and post weaning TDN intake of the calves. Second-order polynomials were fitted through the biweekly efficiency ratios for individual calves and solved to determine the most efficient point. This efficiency was ...


The Wavelength Dependency Of Ultraviolet Induction Of Simian Virus 40 From A Transformed Line Of Baby Hamster Kidney Cells, Timothy Bichenbrenner Jul 1976

The Wavelength Dependency Of Ultraviolet Induction Of Simian Virus 40 From A Transformed Line Of Baby Hamster Kidney Cells, Timothy Bichenbrenner

Masters Theses & Specialist Projects

For our investigation, an established line (E line) of baby hamster kidney cells which was transformed by the incorporation of Simian Virus 40 into the cellular genom was used. The induction of this virion by irradiating these cells with ultraviolet light was studied. The purpose of this thesis was to determine the wavelength dependency (at four selected ultraviolet mercury emission lines) of the induction of the SV40 genome from these cells. The viral titres of induction were measured by the agar overlay plaque assay method and by the fluorescent antibody microassay technique.

At the four wavelengths tested 265 nm and ...


Radioprotection Of Oral Cavity Structures By S-2-(3-Aminopropylamino) Ethyl Phosphorothioate (Wr-2721), Ronald King Jul 1976

Radioprotection Of Oral Cavity Structures By S-2-(3-Aminopropylamino) Ethyl Phosphorothioate (Wr-2721), Ronald King

Masters Theses & Specialist Projects

Studies reporting a high concentration of WR-2721 in mouse salivary glands led to our studies of possible radioprotection of these glands by this drug from ionizing radiation. Oral effects of radiation in the presence of WR-2721 were studied in mice and dogs. Histological evaluation of mouse salivary glands irradiated with 1000 rads of 60Co showed essentially no difference between control and experimental animals. Almost full regeneration of the serous salivary components occurred by 6 months in both groups and neither group had changes in the mucous glands. The use of higher doses of radiation in the mouse was prevented ...


Parasites Of California Marine And Estuarine Fish, Milton S. Love, Mike Moser Jun 1976

Parasites Of California Marine And Estuarine Fish, Milton S. Love, Mike Moser

Faculty Publications from the Harold W. Manter Laboratory of Parasitology

While working on the parasites of several California marine fish, it was difficult to find out which parasites had been reported from our fish. Pertinent sources were scattered over a number of journals, covering many years. We compiled this list because we felt there was a need for a single source which would give all the parasites infecting California marine fish. As "marine fish" was a somewhat vague term, we decided to use it in a broad sense and included estuarine and anadromous fish in the survey. In addition, we have included records from landlocked populations of anadromous fish, such ...


An Evaluation Of The Effectiveness Of Antibiotic Treatment At A Prebreeding Estrus On Subsequent Reproductive Efficiency, Kenneth C. Lamar Jun 1976

An Evaluation Of The Effectiveness Of Antibiotic Treatment At A Prebreeding Estrus On Subsequent Reproductive Efficiency, Kenneth C. Lamar

Masters Theses

An experiment was conducted to evaluate the effectiveness of a douche with an antibiotic formula to improve reproductive efficiency in dairy cows.

A total of 102 cows was utilized in the experiment. The 81 Holstein cows were divided into four groups. These groups were untreated cows which had normal post-calving recuperation (N-C), treated cows with had normal post-calving recuperation (N-T), untreated cows which had experienced post-calving complications (M-C), and treated cows which had experienced post-calving complications (M-T). The 20 Jersey cows were divided into treated and untreated groups (N-T and N-C). The treatment consisted of a nitrofurozone-neomycin mixture in a ...


Comparison Of Wild And Hatchery Brook Trout In Spruce Flats Branch, Great Smoky Mountains National Park, W. Douglas Harned Jun 1976

Comparison Of Wild And Hatchery Brook Trout In Spruce Flats Branch, Great Smoky Mountains National Park, W. Douglas Harned

Masters Theses

The brook trout of Great Smoky Mountains National Park at one time were found to inhabit many mountain streams down to an elevation of approximately 610 meters (2,000 ft.). The range of the species has since decreased at an alarmingly rapid rate in most drainages since the early part of this century. Reasons for the disappearance of the only salmonoid native to the southern Appalachians appears to be a combination of factors. Among them, improper logging practices and the widespread introduction of the rainbow and brown trout are probably the most detrimental. The purpose of this study was to ...
