Characterization Of Field Populations Of Magarites Pupillus (Gould) (Gastropoda, Prosobranchia), Stephen Craig Schroeter
Characterization Of Field Populations Of Magarites Pupillus (Gould) (Gastropoda, Prosobranchia), Stephen Craig Schroeter
Theses and Dissertations
Field populations of Margarites pupillus (Gould), a numerically abundant prosobranch mollusc occuring on rocky shores in Puget Sound, Washington, have previously received little autecological attention. Seawater table studios and SCUBA observations led to the following conclusions: Populations of Margarites are primarily subtidal. Population density and growth are directly related to algal canopy density. Algal canopy may function in reducing predator efficiency, Margarites populations have a 1:1 sex-reatio and no size dimorphism. Sexually mature individuals live for at least two years, and possibly more than four years.
Helminths Of Sceloporus Lizards In The Great Basin And Upper Colorado Plateau Of Utah, Richard Carlyle Pearce
Helminths Of Sceloporus Lizards In The Great Basin And Upper Colorado Plateau Of Utah, Richard Carlyle Pearce
Theses and Dissertations
This study was prompted by the scarcity of information on helminths in Sceloporus lizards of Utah. It reports these worms and includes references to parasites of reptiles in the appendix. A microscopic examination of the coelom, mesenteries, liver, lungs, esophagus, stomach, and intestines of 55 lizards was made, but helminths were recovered only from stomachs and intestines. Examination of S. graciosus yielded Opchoristica scelopori, a cestode found in the duodenum, and Cyrtosomum penneri, C. readi, and C. heynemani, three nematodes of the cecum. The latter two are new nematodes for this host species. Examination of S. undulatus yielded three new …

Extending Lactation Records In Progress To 305-Day Equivalent, J. F. Keown, L. Dale Van Vleck
Extending Lactation Records In Progress To 305-Day Equivalent, J. F. Keown, L. Dale Van Vleck
Department of Animal Science: Faculty Publications
The data consisted of 204,558 complete Holstein lactations in 2,100 herds compiled by the New York Dairy Records Processing Laboratory from 1959 to 1969 All lactation records had to have a 9th or 10th test day to be complete. The generalized least squares analysis used a model including mean, herd-year, and season-age-stage as fixed effects. The error term included random effects of con, and residual variation. Means for specified stages of lactation for milk and fat were estimated for lactations 1, 2, 3, and 4 or greater which were grouped by age of freshening, two age groups for the first …

A Study Of The Seasonal Incidence Of The Arthropod & Helminth Parasites Of The Prairie Vole, Microtus Ochrogaster, & The Wood Mouse, Peromyscus Leucopus, In An Area Of Warren County, Kentucky, Richard Buckner
Masters Theses & Specialist Projects
One-hundred and fifty Microtus ochrogaster and one-hundred and fifty-five Peromyscus leucopus were examined for arthropod and helminth parasites during a study from November, 1970 through November, 1971. The mean monthly burdens, per host, of each species of parasite and observations on the seasonal incidence of each species are reported.
Nineteen species of arthropod parasites were found; these include eight species of mites, two of chiggers, one of ticks, two of lice, five of fleas, and one of hots. Most of these species exhibited very little host specificity, although there was a definite host preference. Heavier ectoparasite burdens were found on …

Livestock Feeding: What Small Feeders Are Doing In Nebraska, Allen C. Wellman, Jeffrey L. Jorgensen
Livestock Feeding: What Small Feeders Are Doing In Nebraska, Allen C. Wellman, Jeffrey L. Jorgensen
University of Nebraska-Lincoln Extension: Historical Materials
Specific data about how smaller Nebraska feeders are marketing their livestock has not been readily available. This is a report of a survey which was conducted in order to analyze the marketing practices of these livestock feeders and the changes in their marketing practices over a five-year period.
The objectives of this study are (1) to determine whether direct sales of fed cattle to packers is increasing in Nebraska as national trends indicate, (2) to obtain a general picture of the current state of the livestock marketing system for small feeders in Nebraska, and (3) to forecast possible trends for …

Spiny Lobster Mariculture In The State Of Florida, W. Richard Boehmer
Spiny Lobster Mariculture In The State Of Florida, W. Richard Boehmer
Marine Affairs Theses and Major Papers
The purpose of this paper is to introduce the reader to the Florida spiny lobster, Panuluris argus; to show the economic potential for the mariculture of this species by exposing value and size of the U. S. spiny lobster market; to present Florida’s legal provisions for mariculture and how spiny lobster farming would be acceptable; to indicate the biological considerations for the rearing of spiny lobster larva and postlarva; and to introduce a general plan for the mariculture of spiny lobster, that considers the legal provisions of leasing wetlands in Florida and incorporates the biological considerations of spiny lobster.

Association Of Type Traits With Reasons For Disposal, L. Dale Van Vleck, H. D. Norman
Association Of Type Traits With Reasons For Disposal, L. Dale Van Vleck, H. D. Norman
Department of Animal Science: Faculty Publications
Reasons for disposal of 3,475 cows from 188 New York Holstein herds were compared with type appraisal and milk yield in first lactation to study the relationship between type traits measured early in life and later reasons for disposal. Reasons for disposal were grouped as production (32%), udder (22%), reproduction (27%), inabilities or disease (8%), workability (3%), type (3%), and other (5%). Few traits measured before 49 months of age had any significant value in predicting the reason for a cow's eventual disposal. These results in addition to earlier studies of heritability suggest that type traits measured in the first …

Potential Of Pompano Mariculture In Florida, James Anthony Elias
Potential Of Pompano Mariculture In Florida, James Anthony Elias
Marine Affairs Theses and Major Papers
Pompano mariculture is not an attempt to bridge the protein gap, but it has been initiated to provide a constant source of this highly desired marine fish. The current market for pompano is small, however, this has been attributed basically to its supply. It appears from the literature that T. carolinus has the most dominant market position since it has an excellent flavor and sports fishermen prefer it due to its fighting ability when hooked on light tackle. It appears from the published history of attempts to raise pompano, by Berry and Iversen, that one of the major problems in …

The Hyobranchium And Throat Myology Of The Adult Ambystomidae Of The United States And Northern Mexico, John E. Krogh, Wilmer W. Tanner
The Hyobranchium And Throat Myology Of The Adult Ambystomidae Of The United States And Northern Mexico, John E. Krogh, Wilmer W. Tanner
Brigham Young University Science Bulletin, Biological Series
The 16 species and subspecies of the Ambystomidae of the United States are placed into six groups according to their throat morphology as follows: The Dicamptodon group, the Rhyacotriton group, the A. Annulatum–A. cingulatum group, the A. gracile-A. jeffersonianum-A. mabeei-A. macrodactylum-A. maculatum group, the A. talpoideum group, the A. opacum-A. texanum group, and the A. rosaceum-A. t. tigrinum-A. t. melanostictum-A. t. nebulosum group. Dicamptodon appears to be the most primitive group and Rhyacotriton the most specialized. Based on the morphology of the throat region it is suggested that A. rosaceum be placed in the tiger salamander group as a subspecies …
Tissue Mineral Imbalances In Cattle With Brisket Disease, Patricia H. Field
Tissue Mineral Imbalances In Cattle With Brisket Disease, Patricia H. Field
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Twenty four cattle, six each of healthy cows and calves, and cows and calves with brisket disease, were obtained, examined and slaughtered. The concentrations of calcium, chloride, cobalt, copper, iron, magnesium, molybdenum, phosphorus, potassium, sodium and zinc; and percent absolute dry matter and percent ash were determined in tissues selected from the following: cardiac, hepatic, renal, osseous, whole blood and blood serum. In addition, certain physical and biological parameters were recorded for each animal. The results were analyzed as a 2 x 2 factorial, segregating the effects of age and brisket disease, and the age-disease interaction.
The following statistically significant …
