Bear River: A National Wildlife Refuge, Vanez T. Wilson, Rachel Carson

United States Fish and Wildlife Service: Publications

In the autumn of 1824 a buffalo-hide canoe drifted down the Bear River to its mouth in the Great Salt Lake of Utah. Within sight of that vast inland sea, Jim Bridger must have paused in amazement. Everywhere he looked-in the sky, on the open water, over the marshy borders of the lake-there were birds. It is said that the famous explorer of the western wilderness brought back reports that he had that day seen "millions of ducks and geese."

The Bear River marshes were soon to know years when their waterfowl were numbered, not by millions, but by thousands; …

Some Observations On The Embryology And The Weberian Apparatus Of Catostomus Ardens (Jordan And Gilbert), H. Ronald Frogley

Theses and Dissertations

The purpose of this study is to add to our knowledge of the embryology and osteology of the Weberian apparatus as found in the sucker, Catostamus ardens J. & G. ot Utah Lake. Observations were made on the embryological development for twenty one days. This information has been discussed and pictures showing the development included. The literature on the osteology ot the Weberian apparatus was reviewed and it is believed that this study presents the first descriptions of the bones of this species. The ossicles were found to be comparatively stable within species indicating some taxonomic value. More study is …

A Comparative Histological Study Of The Adrenal Gland Of Native Rabbits, Ernest I. Gonzalez

Theses and Dissertations

A review of the literature shows that extensive work has been done on the morphology and histology of the adrenal gland of the domesticated rabbit, but it appears that little or no work has been done on other members of the order Lagomorpha. Approximately one hundred specimens of rabbits of various ages and sizes, and of both sexes, were collected over a period of nine months. All adrenal glands were fixed by immersion and were embedded in paraffin. The majority or the glands were sectioned at eight or twelve miora, and were stained with Mallory's triple stain. This investigation shows …

Peromyscus Populations As Related To Seasons And Vegetative Types At The Hardware Ranch, Cache County, Utah, George Cleveland Turner Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Members of the genus Peromyscus, White-footed Mice, are known to occur in nearly all habitats of North America. Because of their numerical abundance and widespread distribution, these mice are extensively used in the study of the dynamics of animal populations. Thus, information perteining to the local distruibution and activities of these mice is of value to the more comprehensive studies that are being carried out in the field of zoological research.

A Survey Of Plant Parasitic And Associated Species Of Nematodes In The Carrot Producing Area Of Cedar Valley, Iron County, Utah, Paul R. Fitzgerald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant parasitic nematodes have long been known to cause extensive crop losses through reduced yields, shortened productive life, or lowered value of produce. The rood knot nematode, Heterodera marioni, is cosmopolitan. It destroys crops and causes economic losses equal to those of any other plant parasitic species. in 1948 this nematode caused an estimated loss to the carrot raising industry in Iron County, Utah of approximately $15,000. No estimates for the years prior to 1948 are available; however, reports of the county agent (14) for Iron County show that carrot production in the Cedar Valley is decreasing, and is …

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, …

A Comparative Anatomical Study Of The Digestive Systems Of The Desert Jack Rabbit And The Pika, Dale Stanley Rupert

Theses and Dissertations

It is the purpose of this study to make gross and histological comparisons of the various segments of the intestinal tracts of the jack rabbit and the pika. The two animals used for this study were the desert jack rabbit (Lepus Californicus deserticola Mearns), and the pika (Ochotona princepts uinta Hollister). The jack rabbits were found only in the desert valleys and low foothills in the areas studied. These areas are typically open bush or sage brush types of communities. The pikas were restricted to certain high rockslides in this region. These areas are described more completely in the section …

A Survey Of The Microflora Obtained By Flushing The Normal Bovine Uterus, Johannah Jane Wulf

Electronic Theses and Dissertations

Since artificial insemination has become a reality and the potentialities of ova transfer are being investigated by several research workers, it seems reasonable to assume that some attention should be directed toward gathering information regarding the bacterial flora of the normal bovine uterus. Both artificial insemination and ova transfer require the insertion of foreign bodies or instruments into the uterus. When such instruments enter this organ, there is always the possibility of introducing various kinds of bacteria. Very little information is available regarding the pathogenicity of these bacteria in the bovine uterus. The possibility of abortion due to such pathogenic …

Influence Of Winter Housing Conditions On Growth Rates And Feed Consumption Of Dairy Heifers, Emery H. Bartle

Electronic Theses and Dissertations

It is important in dairy cattle management to maintain steady and continuous growth of heifers and thereby secure properly developed cows which will give the production that is expected of them when they are brought into the milking herd. In general, heifer calves during the first twelve months of their growing period are carefully managed as to feed, housing and care to promote normal growth. However, they are often neglected during their yearling stage to the point where growth is retarded because of environment factors. On many dairy farms in the North Central States the management of yearling dairy heifers …

Leaflet No 1000 - Rate Of Milking With Machines - Further Results From Western Australian Herds, R. A. Bettenay

Bulletins 1 - 2999

IN an earlier article by this Department (Vol. XXVI No. 2 PP. 99-104) some introductory remarks were made on a study being conducted on the rate of milking by machine, and preliminary findings were recorded. The conclusion was reached that the rate of milking on most farms was too slow, it being considered that in the vicinity of five minutes per cow should be sufficient under machine milking and that, if the teat cups were left on for a longer period than this, damage to the udder was likely to follow.

Leaflet No 1002 - Swine Paratyphoid (Salmonellosis Necrotic Enteritis), C R. Toop

Bulletins 1 - 2999

Paratyphoid is an infectious disease of pigs which is likely to make it appearance wherever pig raising is practised.

It may occur in an acute septicaemic form which is often rapidly fatal and accompanied by serious mortality and in a sub-acute or chronic form known as necrotic enteritis which is characterised by unthriftiness and scouring. The out breaks occurring in Western Australia are principally of the acute type and they are usually associated with the introduction of pigs from saleyards.

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 …

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.
