Hive And Field Mortality Of Honey Bees In Northern Utah Due To Effects Of Certain Ecological And Chemical Factors, Shih Chun Ma
Hive And Field Mortality Of Honey Bees In Northern Utah Due To Effects Of Certain Ecological And Chemical Factors, Shih Chun Ma
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The honey bee is the most important pollinating insect in Utah, because various important crops such as fruits, legumes, and vegetable seed crops depend chiefly on it for pollination. In the past, honey bees have suffered repeated severe death losses through contact with arsenic and other agricultural chemicals. Recently the newer insecticides, such as DDT, chlordane, parathion, benzene hexachloride, lindane, toxaphene, and several kinds of miticides have further complicated the problem of bee survival. In addition, natural enemies such as predators and parasites and some unfavorable environmental conditions, including unfavorable temperature and humidity, wind, storm, and other changeable weather conditions, …

Observations On A New Cystophorous Cercaria From Marine Snails, Jack Edward Copsey
Observations On A New Cystophorous Cercaria From Marine Snails, Jack Edward Copsey
University of the Pacific Theses and Dissertations
A survey of the trematode parasites of marine fishes of Tomales and Bodega Bays, California, was instituted In the Spring of 1948. Many adult forms were obtained, but the search progressively narrowed Itself to a study of the larval trematodss of an area of Tomales Bay, known, as Nick's Cove. Here an interesting cystophorous cercaria was discovered in the littoral snail, Thais emarglnata.

Studies On The Ecological Distribution Of The Genus Tegula At Bodega Bay, California, Allen Emmert Breed
Studies On The Ecological Distribution Of The Genus Tegula At Bodega Bay, California, Allen Emmert Breed
University of the Pacific Theses and Dissertations
This paper is primarily a study of the factors contributing to the distribution of Tegula funebralis and Tegula brunnea in the vicinity of Bodega Bay, California. The two species seldom appear extensively together in the same zone. Tegula brunnea is found on the exposed outer coast of Tomales Point, but not in the immediate zone of Tegula funebralis. Tegula funebralis is found at some points north of Dillon Beach, but it is rarely in the presence of abundant Tegula brunnea. The writer hopes that his efforts may lay a basis for more ecological studies of this genera on the Pacific …

Trypanosoma Barbari, A New Species From The Newt Triturus Torosus, Donald Lewis Lehmann
University of the Pacific Theses and Dissertations
Whlle making studies of the parasites of fishes and amphibians at the Pacific Marine Station, Dillon Beach, California, during August, 1949, the writer encountered a hitherto unreported trypanasome from a female Triturus torosua. From the information obtained from the one smear, which was stained, the animal was presumed to be monomorphic, However, during February, 1950, a search was made expressly for the purpose of' obtaining specimens of this Pacific Coast newt, and of the eight animals examined six were parasitized. Contrary to the primary observations, evidence was accumulated which proved beyond any doubt that the flagellate is polymorphic and that, …

Crop Damage By Wildlife In California ; With Special Emphasis On Deer And Waterfowl, Earl Roy Biehn
University of the Pacific Theses and Dissertations
The problem of crop damage by wildlife is not a new one in California, but it has assumed a role of major economic importance only during the last few decades. Since this problem was first encountered in California, it has steadily increased in size and scope, until today in many areas of the state it is an important economic problem of the farmer; a pressing management problem for the biologists and wildlife technicians of the California Division of Fish and Game; a constant challenge to the game management agents of the Federal Fish and Wildlife Service; a great concern of …

The Lemming Vole, Synaptomys Borealis, In Northern Minnesota, Ralph M. Wetzel, Harvey L. Gunderson
The Lemming Vole, Synaptomys Borealis, In Northern Minnesota, Ralph M. Wetzel, Harvey L. Gunderson
University of Nebraska State Museum: Mammalogy Papers
Lemming voles of the subgenus Mictomys have never been recorded from north-central United States, although they might be expected to occur there judging from records of the species Synaptomys (Mictomys) borealis from southern Manitoba. Recently, examination of specimens in the collection of the Minnesota Museum of Natural History reveals that Synaptomys borealis does occur in north-central United States for we have found the following specimens referable to that species: one immature female (No. 951, MMNH) from Williams, Lake of the Woods County, Minnesota, collected by Gustav Swanson, August 5, 1932; one adult male (No. 2552, MMNH) from Warroad, Roseau County, …
Studies On Larval Trematodes From Tomales Bay, California, Leroy H. Fisk
Studies On Larval Trematodes From Tomales Bay, California, Leroy H. Fisk
University of the Pacific Theses and Dissertations
Very little is known of the development, life history, economic importance, of biological relationships of larval trematodes, especially in their molluscan and arthropod hosts on the Pacfic Coast. The comparatively few contributions to our knowledge have been from scattered and fragmentary observations. The purpose of this study was to expand our knowledge and to lay a foundation for further work on trematode life cycles in marine organisms. The area selected for special investigation was Nick's Cove, Tomales Bay, California.

A Survey Of The Adult Trematodes From Fishes Of The Pacific Marine Station Area, William Franklin Johnson
University of the Pacific Theses and Dissertations
An effort is here made to assemble all of our knowledge of all adult trematodes which have been found in the fishes of the Pacific Marine Station Area. This includes publications, unpublished material such as graduate theses, and specimens herein described for the first time. It is hoped that this endeavor will facilitate further investigation in trematodology and that this paper will be an aid in identification of trematodes subsequently discovered.

Mule Deer Record For Minnesota, Harvey L. Gunderson
Mule Deer Record For Minnesota, Harvey L. Gunderson
University of Nebraska State Museum: Mammalogy Papers
During the hunting season of 1947, Leonard Nygren shot a deer near Pillager, Cass County, Minnesota. The deer, which weighed 153 pounds dressed, was disqualified in a sportsman's contest because it was not considered a white-tailed deer, according to a newspaper report. The report was investigated and the animal in question was identified as a mule deer, Odocoileus hemionus. This extends the known range of this deer in Minnesota nearly 100 miles to the east. John Jarosz, Museum Preparator, and the writer went to Nygren's place nine miles north of Pillager and measured and skinned the animal which is …

A Study Of The Littoral Marine Isopod Crustacea Of The Dillon Beach Area, Robert James Menzies
University of the Pacific Theses and Dissertations
The primary purpose of this study was to provide accurate diagnoses of the littoral marine isopod crustacea in the Dillon Beach area. Such a purpose involved a much more complete study of the anatomy of the species represented in the fauna than was heretofore performed. Certain anatomical structures deemed by earlier writers as specifically diagnostic are demonstrated to be unreliable and in a great many instances other structures previously neither described or figured by American writers are considered of paramount importance in species identification. The number and magnitude of the changes proposed in this paper as illustrated in outline form …

A Study Of A Heron Nesting Colony, Linden J. Leatham
A Study Of A Heron Nesting Colony, Linden J. Leatham
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Herons are well known because of their gregarious nesting habits. Like many others of the lower orders of birds they nest together in pure or mixed colonies of many different combinations and under diverse living conditions. The population of different colonies may vary from a few pairs to many thousands of pairs depending upon the nature and extent of the breeding area, the food supply available and the protection afforded either by natural or artificial means.
In Utah and adjacent areas of bordering states, many types of heron associations have been studied and reported by ornithological workers. Breeding colonies of …

A Survey Of Intestinal Protozoa At The Stockton State Hospital : Stockton, California, Lawrence Melvin Gholz
University of the Pacific Theses and Dissertations
During the past months much has been published in periodicals, especially those of a pictorial nature, which discredits institutions established for the care of' the mentally ill throughout the nation. Many articles have been presented which show an intelligent approach, but the majority of these treatments are by those who are basing too much on a very narrow experience. For example, one news magazine recently printed a picture of a mental patient in institutional garb sitting on a bench in one of the poses most characteristic of a catatonic. The caption of the picture seemed to ignore this significant fact …
