Evicting Bees From Houses, A C. Kessell

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

EACH year the Apicultural Branch receives several inquiries from harassed householders about how to get rid of bee colonies which have nested in houses.

Cavity walls often provide cosy quarters for swarms seeking: a home, while others establish themselves in chimneys, ventilators and under floors.

Age And Growth Of The Rio Grande Mountain Sucker, Pantosteus Plebeius (Baird And Girard), Richard R. Raush

Biology ETDs

Seven hundred and forty-four specimens of the Rio Grande mountain sucker collected in Jemez Creek, a tributary in the Rio Grande system, were measured, sexed and aged. Both length-frequency and scale methods were used to determine the age of these specimens. The oldest males were six years of age, at which time averaged 134 mm in standard length. The oldest females were seven years of age, and average 159 mm in standard length. First spawning for both males and females occurred in the spring after they had completed three full years of life. The onset of senescence, expressed as a …

Development Of Circadian Sleep-Wakefulness Rhythm In A Healthy Boy Gauged By Circadian Quotients, Ellen Reeker, Michael Diffley

Journal of the Minnesota Academy of Science

The circadian quotient, briefly CQ, serves to estimate the prominence of a rhythm with a period of about 24 hours. The CQ may be computed from so-called variance spectrum analysis, among other procedures ( 1) . Computational details and some applications have been discussed earlier (1 , 2). We wish to illustrate herein the use of the CQ for gauging the development of a circadian sleep-wakefulness rhythm in the senior author's first-born child, FAR, also documented in general terms, elsewhere ( 3).

Apparent Effects Of Refrigeration On The Rate Of Embryonic Development Of Mayfly (Hexagenia Limbata) Eggs, Roger Flattum

Journal of the Minnesota Academy of Science

Hunt (19 5 3) states that temperature is an important factor influencing the rate of embryonic development of Hexagenia (mayfly) eggs. Pasvogel (1962) has reported that 46 days is the time limit Hexagenia eggs can remain dormant at temperatures slightly above freezing. It was the object of this investigation to continue this line of research and to determine the effects of temperature on the embryonic development of Hexagenia limbata eggs.

A Study Of The Microflora Of Root Beer, Leah Morford Senff

University of the Pacific Theses and Dissertations

The purpose of the present work was three-fold: (1) to determine the number of microorganisms found in root beer ready for consumer used, (2) to study the effects of various temperatures and durations of incubation on this microbial population, and (3) to characterize the predominant species of contaminating bacteria.

Comparative Anatomy And Biology Of Two Species Of The Asteroid Genus Pisaster, Norman William Mayer

University of the Pacific Theses and Dissertations

Interest in the endemic Pisaster was first aroused by the great variation of external color in Pisaster ochraceus. This in turn led to observations of the diversity of the spinous patterns of this sea star. Following the suggestion of Dr. Jool D. hedgepeth it was decided to make an extensive comparison of the common species of Pisaster.

Detailed comparison between Pisaster brevispinus and Pisaster ochraceus have been made only by Fisher (1930) and Verrill (1914). Both of these investigators restricted their observations largely to the endoskeleton and its calcareous protuberances. In addition to analyzing the work of Fisher, an attempt …

On The Use Of Tris (Hydroxymethyl) Aminomethane As A Diluent In Quantitative Analyses Of Soil Bacteria, Barry L. Keller

Masters Theses

Introduction

Many investigations have been conducted in the field of soil microbiology during the past.six decades. Most notable among the contributors is S. A. Waksman whose voluminous works have established many of the procedures used in microbial analyses of soil. Yet, the one fact that is foremost to any reviewer of the literature covering this field is that no standardization of techniques for soil analyses exists. The following presentation deals with one method used to estimate the number of bacteria and actinomycetes in soil.

The use of Tris(hydroxymethyl)aminomethane (hereafter referred to as "Tris") is not new. Tris currently is used …

A Histomorphological Comparison Of The Urinary Systems In The Serranid Fishes, Roccus Sexatilis (Walbaum) And Roccus Americanus (Gmelin), Irwin Beitch

Master's Theses

The urinary systems of Roccus saxatilis (Walbaum) and Roccus Americanus (Gmelin) were studied to check the validity of the monogeneric classification and to examine the osmoregulatory mechanism that allows the species to survive in environments of various salinities. The gross anatomy of the urinary systems of 13 R saxatilis and 12 R. americanus showed a number of similarities to exist, e.g. the general mesonephric form and size, uretal position and length, and the renal venous system. The head kidney, a hemopoietic organ, was larger in R. ­saxatilis than in R. americanus. Histological comparisons were made of H and E serial …

Some Effects Of Ph, Temperature And Light On The Production Of Zoosporagia In Saprolegnia Parasitica Coker, Philip C. Lee

Master's Theses

Pure cultures of Saprolegnia parasitica Coker were grown under varied conditions of temperature, pH, and light conditions. In liquid medium colonies were spherical with a zonal effect in the distribution of zoosporangia.

Near the limiting extremes of pH and temperature, beaded hyphal tips were found in place of normal sporangia. Teorell Universal buffer in the sporulation water inhibited production of sporangia. The pH minimum was 4.0 - 4.1, optimum 6.3 - 7.4, and maximum 8.o - 8.3. The maximum number of sporangia was produced at 15 C. Between 3.4 and 5 C , a delay in sporulation was noted and …

An Investigation Of The Genetic Basis Of Alcoholism, Daniel F. Malamud

Masters Theses

Introduction

Alcoholism: The Disease

"Alcoholism is a chronic disease manifested by repeated implicative drinking so as to cause injury to the drinker's health or to his social or economic functioning" (53). Such a definition of alcoholism points to the disease concept which went unrecognized until recent years. In addition to its medical implications, alcoholism has been the subject of considerable writing and research by academicians in such diverse fields as sociology, psychology, physiology, psychiatry, theology, and law.

At the outset it should be noted that the writer is aware of the arguments and opinions expressed by the advocates of the …

A Floristic Study Of The Basidiomycetes Of The Sandia Mountains, New Mexico, Horace R. Simms

Biology ETDs

The basidiomycete flora of the Sandia Mountains has never really been investigated before. At best this survey can serve only as a rather spotty general sketch of fungi in the area. But at least it is a beginning, and one which is not slanted just at the pathological aspects. It is my hope that such information as has been uncovered will help in future ecological and taxonomic investigations of the fungi of these mountains.

A Comparison Of Intestinal Protozoa Among Peromyscus And Other Small Rodents Of Bernalillo County, New Mexico, Raymond C. Bowen

Biology ETDs

Biology ETDs

In this investigation I shall attempt to relate pollen percentages of recent sediments to relative phytosociological measures of the vegetation in each of six southwestern vegetational types. The establishment of such relationships will enable more accurate reconstructions of past plant associations and climate from studies of pollen profiles

Age And Growth Of The Longfin Dace, Agosia Chrysogaster Girard, John Kristian Winther

Biology ETDs

This is the first study to determine the age and growth of the longfin dace, Agosia chrsogaster Girard. During March, June, and October, 1961, 8,568 dace were collected from the Mimbres, San Francisco River and one of the Mimbres River indicate that Agosia lives just over one year. Estimates of age based on the examination of scales from a stratified subsample of 255 fish appear to agree with length-frequency estimates. The position of a check near the outer margin of scales established the formation of a winter check in March. Two or more checks appear to be formed each year. …

The Flora Of Mount Taylor, Neal L. Osborn

Biology ETDs

The writer has attempted to determine what species occur on Mount Taylor. This information should reveal any deviations from the expected floristic pattern as well as general distributional trends. If deviations are detected, the writer will attempt to explain them in the general discussion. Most of the answers and conclusions are of a speculative nature because of insufficient meteorologic information and comparative data from other regions.

An Annotated Checklist Of The Bats Of Bernalillo County, New Mexico, Frances Veronica Sheppard

Biology ETDs

In 1960-61, Bernalillo County, New Mexico, was surveyed for bats. The purpose of this survey was to determine what kinds of bats occur in the county and to collect natural history data on these bats. Bats were obtained by cave and roost searching and by mist-netting and shooting over ponds, streams, and tanks. For all bats collected, standard museum study skins and skulls as well as alcoholic carcasses are preserved in the Museum of Southwestern Biology at the University of New Mexico.

Rapid Identification Of Streptococcal Infections Using Fluorescent Antibody Techniques, James H. Meadows

Biology ETDs

The use of fluorescent microscopy coupled with immunological techniques offer new methods for the demonstration of antigen-antibody reactions. The adaptation of these techniques to grouping of beta hemolytic streptococci makes feasible their further adaptation toward identification of group A streptococci in clinical material. Commercially available labeled antibodies against group A beta hemolytic streptococci were obtained for use in this study. A method for the determination of labeled antisera specificity is proposed and a technique for absorbing out any heterologous reacting antibody is described. Using this commercial labeled antisera, subsequent to specificity studies plus absorption if necessary, adaptations of basic fluorescent …

The Effects Of Radium On Certain Goldfish Blood Constituents And Organs, D. Wayne Linn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Background radioactivity from radium has long existed in ground and surface waters of the United States, but in the last 15 years radium has become a consequential unnatural contaminant of waters (Coulomb, 1955; Rone, 1952; Schlundt, 1910; Scott and Barker, 1956; Scott, 1961; and Tsivoglou et al., 1958). The onset of the atomic age initiated the increased processing of uranium ore for its uranium content. Radium is a daughter product and a by-product of uranium ore and its purification (Glasstone, 1958; and Tsivoglou et al., 1958). The uranium refinery wastes are released into streams in which all forms of aquatic …

Factors Affecting The Waterfowl Hunter Utilization And The Waterfowl Kill At The Bear River Migratory Bird Refuge, 1960-61, Stephen V. Goddard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1960 there were 1,955, 000 waterfowl hunters in the United States. These hunters spent $89,431, 000 (an average of $45.74 per individual) and 15,158, 000 hunter days in the field. The hunting population will increase 35 percent by 1975 (Anonymous, 1960).

The large increase in hunters will bring a proportional increase in the demand for places to hunt. Many states face the problem of providing enough public hunting for such an army of sportsmen. Studies by Kozlik (1958) in California, Gordinier (1957) and Friley (1959) in Michigan, and Bednarik (1957, 1961) in Ohio point out some of the problems …

Food Availability And Selective Utilization By Juvenile Mallards (Anas Platyrhynchos Platyrhynchos L.) On The Bear River Migratory Bird Refuge, Utah, Nicholas J. Chura

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This investigation was devoted to a study of food availability and the selective utilization by juvenile mallards (Anas platyrhynchos platyrhynchos L.) from hatching through the flight stage. Such information furnishes basic knowledge which may be used for determining the effects of chemical poisons on these organisms, how breeding ground habitats could be manipulated for their most efficient use by duckling species, what nutrients occur in natural duckling foods, and the digestibility of these items. The Bear River Migratory Bird Refuge, Utah, was used as the study area during the waterfowl breeding seasons of 1959, 1960, and 1961. Mallard ducklings …

A Comparison Of Cock Pheasant Harvests Among Areas Having Different Hunting Pressures, Cache County, Utah, James C. Bartonek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parsons (1953) found Utah's posted hunting unit system regulated hunting pressures over much of the state's pheasant range. He found inequalities of hunting pressure among the posted hunting units because of their individualistic methods used to determine the number of hunting permits to be sold. Utah State Department of Fish and Game personnel recommend the number of permits to be sold by the hunting unit; but often, the hunting unit officers use the desired level of hunting pressure, size of cock harvest, and revenue from permit sales as decisive factors. By regulating hunting pressure on their own lands the posted …

A Study Of Body Water In Active And Hibernating Ground Squirrels, Citellus Lateralis Lateralis And Citellus Spilosoma Marginatus, Lawrence R. Klinestiver

Biology ETDs

The present studies were designed to evaluate dehydration as a factor in determining duration of hibernation. Skin temperatures were utilized to indicate the condition of hibernation. Two species of animals, Citellus lateralis and Citellus spilosoma, from two different ecological areas, were studied for the purpose of determining whether tolerance for deprivation of water would indicate changes in water content of tissues during hibernation. If hibernation is limited by dehydration of body tissues, then animals with a greater tolerance for dehydration may hibernate for longer periods. The following experiments were designed to evaluate the effects of dehydration on active and …

A Survey Of Parasitism In A Population Of Pigeons, Robert Flynn Jochen

Master's Theses

Numerous papers relative to parasites in pigeons can be found in the literature, but information concerning parasitic infections in pigeons of Virginia is scant, and no survey of parasitism has been made. Furthermore, no one survey or parasitism in pigeons of North America has included the incidence of both ectoparasites and endoparasites. Information relative to the incidence of individual parasites or groups of parasites, however, is available in recent literature, as well as information concerning isolated cases of parasitism

The present study was undertaken to (1) determine the nature and extent of parasitism in a population of pigeons in Henrico …

A Study Of Nematode Parasites Of Some California Salamanders, Herbert Bruce Johnston

University of the Pacific Theses and Dissertations

Little information is available concerning the nematode parasites of salamanders in California. Lehmann (1954) reported the finding of Oxyuris dubia Leidy 1856, in the rectum of 33 Ensatine e. Eschscholtzii from Sonoma County, California, and in 3 of 10 Batrachoseps a. Attenuatus, from San Francisco County, California. He also reported Oxyuris magnivulvaris Rankin 1937 in the rectum of 1 to 2 Aneides flavipunctatus, from Marin County, California and Rhabdias sp., from lungs of 2 of 12 aquatic Triturus torosus from Contra Costa County, California. Lehmann (1960) reported O. dubia from the cloaca of 1 Aneides flavipunctatus and 3 Aneides lugubris …

Cytochemical Studies On Trypanosoma Ranarum, Richard Cecil Brown

University of the Pacific Theses and Dissertations

The location of structures within an organism and the chemical nature of these structures can be determined by cytochemical techniques. Further, such techniques may be used to demonstrate the presence of an enzyme or an enzyme system within the cell. This information can assist in the elucidation of metabolic pathways available to an organism. Despite the apparently large potential value of cytochemical information, few investigations of the cytochemistry of trypanosomes have been reported, and there are no reports available of studies upon cultural forms.

Nigrelli (1929) utilized vital stains and osmic acid impregnation in studies on cytoplasmic inclusions in Trypanosoma …

Relative Growth In Some Antarctic Pycnogonida, William Granow Fry

University of the Pacific Theses and Dissertations

Work on the systematics of a large collection of Antarctic Pycnogohida has revealed very forcibly the limitations of existing systems of classification of this group. In an attempt to rectify some of these shortcomings for a monograph on the pycnogonid fauna of the Ross Sea area, the author has been led to seek new characters and character states which will be useful in taxonomy.

Virtually nothing is known of pycnogonid behaviour and ecology, and it seems unlikely that additional knowledge in these fields will be forthcoming in the near future. Our knowledge of pycnogonid comparative anatomy and histology is also …
