Animal-Sediment Relations In A Tropical Lagoon: Discovery Bay, Jamaica, Robert C. Aller, Richard E. Dodge

Marine & Environmental Sciences Faculty Articles

The distribution of many macrobenthic species in the back-reef lagoon of Discovery Bay, Jamaica can be related to a gradient in bottom stability. This gradient is defined by increasing rates of biogenic reworking and sediment resuspension in the western part of the lagoon. Infaunal diversity and coral growth decrease in the western, unstable areas. The infauna of the carbonate sand consists mainly of deposit feeders. In the western lagoon, the feeding activities of this group result in high biogenic reworking rates (up to 6-7 cm/week) producing loose surface sediment easily resuspended by waves. A maximum, mean resuspension rate of 19 …

Induced Changes In The Rates Of Uridine-3H Uptake And Incorporation During The G1 And S Periods Of Synchronized Chinese Hamster Cells, Peter J. Stambrook, Jesse E. Sisken

Biology Faculty Publications

The rates of uridine-5-³H incorporation into RNA and the rates of uridine uptake into the acid-soluble pool during the cell cycle of V79 Chinese hamster cells were examined. Cells cultured on Eagle's minimal essential medium supplemented with fetal calf serum, lactalbumin hydrolysate, glutamine, and trypsin displayed rates of incorporation and uptake which increased only slightly during G₁ and accelerated sharply as DNA synthesis commenced. In contrast, cells cultured on minimal essential medium supplemented only with calf serum exhibited rates of incorporation and uptake which increased linearly through both G₁ and S. The transition from one pattern …

Aspects Of The Oculomotor System Of Callinectes Sapidus, Antoinette Steinacker

University of the Pacific Theses and Dissertations

An isolated perfused preparation was developed for the study of several aspects of the oculomotor system of the blue crab, Callinectes sapidus. The system for eyestalk rotation was investigated on an extracellular level. Two antagonistic pairs of muscles under visual and statocyst control were found to be responsible for stabilization and rotation of the eyestalk. The primary sensory input to the muscles appears to be from the statocysts, with both static position sense and dynamic acceleration components influencing the motor response. Two sensory feedback systems from mechanoreceptive hairs were found which influence the response of the eye stalks to statocyst …

A Taxonomic Comparison To Uta Stansburiana Of The Great Basin And The Upper Colorado River Basin In Utah, Lloyd C. Pack

Theses and Dissertations

The lack of a comparative study between the Uta stansburiana of the Great Basin and Upper Colorado River Basin, and the fact that several reptile species have developed distinct populations in the Upper Colorado River Basin prompted this study. Twenty-one external characteristics of these lizards were compared, including several which had not been previously used in the separation of Uta stansburiana into subspecies. All of the statistical data were obtained from preserved specimens. Twelve of the twenty-one characteristics show significant differences between the Great Basin and Upper Colorado River Basin populations. The characteristics of back pattern and throat color show …

Why Does Second-Cutting Red Clover Hay "Slobber" Animals, J. Kenneth Evans, A. S. Williams, D. E. Labore

Agronomy Notes

For years, farmers have noticed the slobbering of animals after feeding second-cutting red clover hay. Severity of this effect, however, has varied from year to year. Questions asked many times are what causes the slobbering and what can be done about it? To get the answers available, let's go back about 37 years into something which appears to be totally unrelated to slobbering and follow research which has been done on a fungus, which causes a disease of red clover.

Mammalian Distribution Within Biotic Communities Of Northeastern Jewell County, Kansas, Kenneth W. Andersen, Eugene D. Fleharty

Fort Hays Studies Series

The purpose of this investigation was threefold. First, to obtain as complete a list as possible of mammals occuring in the area through collecting and observational procedures. Second, to determine their specific distribution within the study area, and third, to correlate and elucidate the relationships between their distribution and the major vegetational regions within the study area.

Distribution Of Native Mammals Among The Communities Of The Mixed Prairie, Edwin Perry Martin

Fort Hays Studies Series

From October, 1952, until August, 1958, the small mammals on a relict area near Hays, Kansas, were studied. The observations were undertaken to establish a standard to which the mammals of variously disturbed areas could be compared; also, information concerning the relations of the species of mammals to the communities of the mixed prairie was sought.

Some Effects Of Inorganic Fluoride On Plants, Animals, And Man, Delbert A. Greenwood

Faculty Honor Lectures

~~~ in the compounds of fluorine may be traced to one or more of the following factors: ( 1) the consumption of a drinking water containing one part per million of fluorine as a soluble flouride during the period of calcification and eruption of the teeth causes a reduction in the incidence of tooth decay; however, an intake of drinking water containing more than two parts per million of fluorine causes dental fluorosis of varying degrees in man and certain animals; (2) a continuous intake of excessive amounts of fluorine as mineral supplement, in contaminated forage, or the grazing of …

Javma37-43 Anthrax In Swine, L. Van Es

University of Nebraska-Lincoln Extension: Historical Materials

Anthrax is not commonly considered so important a menace to swine as it is to other forms of live stock, in which the disease is apt to declare itself with terrifying severity. In comparison with the marked mortality frequently observed in cattle, the tangible losses caused by anthrax in swine seem negligible. As recent as 25 years ago, there still were observers who sincerely doubted the occurrence of the disease in hogs and this opinion found some support in the many reported failures to induce the infection in that animal species by artificial methods.

A Study Of Intersexuality As Exhibited In Animal Forms, Ida V. Jaggard

Biology Honors Papers

This 21 page thesis discusses the entire scope of animal intersexuality with examples illustrating certain types of intersexuality. Much of the thesis is based on the works of F. A. E. Crew and Alexander Lipschutz.

Rb28-229 Fattening Steers Of Various Ages, H.J. Gramlich

University of Nebraska-Lincoln Extension: Historical Materials

During recent years the beef industry has undergone vast changes. These have been made necessary in part by economic conditions and in part by changes in the demands of the American people. The tendency has been toward earlier marketing of steers, so that instead of going to the block as mature individuals at from 3 to 5 years of age, they are now reaching the market at a much younger age. In consuming centers where only heavy carcasses of beef were demanded formerly there is a call today for carcasses of the yearling and long yearling class.
