The Status Of Beavers In The Delta Area Of The San Joaquin River, San Joaquin County, California, 1950-1951, Delbert David Cram Jan 1951

The Status Of Beavers In The Delta Area Of The San Joaquin River, San Joaquin County, California, 1950-1951, Delbert David Cram

University of the Pacific Theses and Dissertations

The term “delta area” refers to a region roughly 40 miles long and 15 miles wide situated 65 miles east of San Francisco Bay where the San Joaquin and Sacramento Rivers join and enter Suisun Bay. The waterways in this area are fresh water from these rivers, but they are affected by the ocean tides and to some extent by the salinity of the ocean water. The rgeion ecompasses about 507,000 acres, most of which has been reclaimed for agricultural purposes by the construction of levees to contain the tides and high waters. The word “islands” is used locally to …

Hive And Field Mortality Of Honey Bees In Northern Utah Due To Effects Of Certain Ecological And Chemical Factors, Shih Chun Ma May 1950

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, …

Crop Damage By Wildlife In California ; With Special Emphasis On Deer And Waterfowl, Earl Roy Biehn Jan 1950

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 …


Observations On A New Cystophorous Cercaria From Marine Snails, Jack Edward Copsey Jan 1950

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 Jan 1950

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 Jan 1950

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, …

The Lemming Vole, Synaptomys Borealis, In Northern Minnesota, Ralph M. Wetzel, Harvey L. Gunderson Jan 1949

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, …


A Survey Of The Adult Trematodes From Fishes Of The Pacific Marine Station Area, William Franklin Johnson Jan 1949

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.


Studies On Larval Trematodes From Tomales Bay, California, Leroy H. Fisk Jan 1949

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.

Mule Deer Record For Minnesota, Harvey L. Gunderson Jan 1948

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 Jan 1948

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 …
