Natural And Experimental Infections Of Thelazia Californiensis Price (1930, Nematoda: Thelaziidae) With Descriptions Of The Adult And Larval Parasites, Howard S. Burnett
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this work was to determine the extent and effects of infestation of the eye worm of mammals, Thelazia californiensis, and to elucidate through experimentation or observation the mode of transmission.
A survey of literature revealed that thelaziasie (infestation by Thelazia species) may cause serious pathological changes in the eye and its adnexa, sometimes resulting in blindness. It was found that reports of thelaziasis in the United States were (with two exceptions) of cases in California. It was further found that T. californiensis has been reported in a wider variety of host than has any of other …

Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson
Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson
Nebraska Game and Parks Commission: Publications
The purpose of this booklet is to provide a ready field reference for identification, sexing and aging of common game species. It has purposely been kept in simplified form, presenting only those techniques which can commonly be applied in the field and avoiding those which would require special equipment and skills. Untrained personnel should be given demonstrations of the techniques, and thereafter this reference should serve as a reminder. It is not expected that the reference could successfully be used without such demonstration. Certain of the techniques such as cloaca! examination of waterfowl may require considerable practice by the individual. …
Research Notes: Experimental Infection With Strigoid Cercariae, Glenn L. Hoffman
Research Notes: Experimental Infection With Strigoid Cercariae, Glenn L. Hoffman
United States Fish and Wildlife Service: Publications
During the summers of 1947 and 1948 strigeoid cercariae from Carrol Lake, Wisconsin were collected and identified by the late Dr. F. G. Brooks and turned over to the writer for use in the experimental infection of frog tadpoles and various fish. It was hoped to establish or eliminate these animals as the second intermediate host. One of the 8 tested was found infective for fish, and 1 infected tadpoles. These records do not elucidate the life cycles of these worms, but it is hoped that the work may help in the future study of strigeoid cercariae.

Studies On The Periodicity Of Certain Plankton Species Of Salem Lake, Gene A. Pratt
Theses and Dissertations
Plankton samples were taken periodically from one station in Salem Lake from the fall of 1955 through the winter of 1957. Other data including the pH, dissolved oxygen content, turbidity, brightness of day, temperature, and time of day were recorded at the time of each collection. The plankton samples were centrifuged and preserved in a 4% formalin solution. They were later examined microscopically, and density, percent density, and percent frequency calculations were made from them for ten selected species and for the five phyla which they represent.

Observations On The White-Faced Ibis, Plegadis Chihi, In Louisiana, Horace William Belknap
LSU Historical Dissertations and Theses
The eight-month study deals with the White-faced Ibis, Plegadis chihi, in southwestern Louisiana. It affirms the absence of the closely related Glossy Ibis, Plegadis falcinellus, as a breeding bird in that area today. Data on feeding habits, social behavior, nesting cycles, and plumage changes in chihi are presented as a step toward clarifying the relationship of these two puzzling forms of ibis; but the full significance of these findings cannot be ascertained until more is known about the habits of falcinellus. The most important conclusions concern plumage changes. It is shown that published descriptions of plumage and molt in chihl …

Evidence Against The Transmission Of Staphylococci By The Mosquito Culex Tarsalis, John R. Molenda
Evidence Against The Transmission Of Staphylococci By The Mosquito Culex Tarsalis, John R. Molenda
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Staphylococcal synovitis is a pathological condition of birds involving primarily the wing and leg joints. It is frequently referred to as arthritis, osteoarthritis, bursitis, hock disease, staphylococcosis, and weak leg.
The disease has been reported throughout various parts of the world as having been found in a great variety of avian hosts including pheasants, chickens, pigeons, canaries, geese, ducks, grouse, and turkeys.
Miner (1945) presented results of a survey made on turkey diseases in Sanpete County, Utah, which indicated staphylococcal synovitis to be responsible for the greatest numbers of deaths. His report cites this infection as having been found in …
The Use Of Branchiostegal Rays To Determine Age Of Lake Trout Salvelinus Namaycush Walbaum, Ross Vivian Bulkley
The Use Of Branchiostegal Rays To Determine Age Of Lake Trout Salvelinus Namaycush Walbaum, Ross Vivian Bulkley
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Any method used in aging fish must fulfill certain requirements to be satisfactory. If the method is inaccurate, naturally little reliance can be placed upon its use. If considerable study of the method and much practice are required before accurate readings can be obtained, the method will not come into widespread use. The requirements of an aging method, then are that it must be accurate and comparatively easy. The scale method for aging lake trout (Salvelinus namaycush Walbaum) unfortunately does not fulfill these requirements. It has always been difficult to tell the age of lake trout by the examination …

Protein And Fat Requirements Of Baby Pigs, E. R. Peo, Jr., G. C. Ashton, V. C. Speer, D. V. Catron
Department of Animal Science: Faculty Publications
Present day research in swine nutrition with its early weaning programs and its use of the baby pig in biological assays has necessitated the determination of the nutritional requirements of the baby pig. The requirements for two of these nutrients (protein and fat) have not been clearly established. Early studies on the protein and fat requirements of baby pigs were conducted with liquid synthetic milk diets, which were formulated generally on the basis of the composition of sow milk.

Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard
Nebraska Game and Parks Commission: Publications
IN COMMON with the experience of most states, Nebraska's deer herds were reduced to a very low level by excessive harvests in our early history. Most American big-game animals were overharvested in the early history of this nation because of commercialization. Buffalo were killed for their hides, deer for their meat. This slaughter continued as long as the hunter (or poacher) could sell his take at a profit. Modem game management and public opinion reversed this trend. Deer are on the way back all over America, and in some states the protection-complex was so strong that deer were restored to …

Gyrodactylus Eucaliae N. Sp. (Trematoda: Monogenea) From The Brook Stickleback, Eucalia Inconstans*, Glenn L. Hoffman, Francis M. Ikezaki
Gyrodactylus Eucaliae N. Sp. (Trematoda: Monogenea) From The Brook Stickleback, Eucalia Inconstans*, Glenn L. Hoffman, Francis M. Ikezaki
United States Fish and Wildlife Service: Publications
A new species of Gyrodactylus was observed on the skin, gills, and fins of the brook stickleback from the English Coulee, Grand Forks, North Dakota during the summers of 1953-1955. Host-specificity is usually striking in the monogenetic trematodes and since this parasite was not observed on any other species of fish from this body of water or the nearby Turtle River, it was studied in detail and is here described as a new species, G. eucaliae.
