Food And Feeding Habits Of The Rio Grande Mountain-Sucker, Pantosteus Plebeius (Baird And Girard), James A. White

Biology ETDs

The initial purpose of this work was to study the rela­tionship between Pantosteus plebeius (Baird and Girard), the Rio Grande mountain-sucker, and Catostomus commersoni (Lacépède ), the common white sucker, in Jemez Creek drainage, Sandoval County, New Mexico. Because insufficient informa­tion on Catostomus commersoni could be obtained, the food and feeding habits of Pantosteus plebeius were studied as an al­ternative.

Mountain-suckers were captured and observed in Jemez Creek drainage. The intestinal contents of 145 specimens were ex­amined in detail. The intestinal contents of other specimens were examined cursorily.

Pantosteus plebeius are omnivorous and they use a pair of cartilaginous jaw …

A North Temperate Bat Community: Structure And Prey Populations, Hal L. Black

Biology ETDs

Food habits and food partitioning were investigated in a North Temperate insectivorous bat community. Analysis of fecal pellets showed that all species of bats utilized moths and most species utilized beetles. There appears to be differential utilization of these two prey items. Six species of bats are moth strategists and four species are beetle strategists. In one species, Eptesicus fuscus, changes in food selection is correlated with changes in food abundance.

Food habits are discussed in relation to various parameters of the prey populations, i.e., abundance, activity, and length class diversity. Habitat partitioning is discussed in relation to type of …

Cellular Absorbed Dose Spectrometer (Cads) Data Reduction And Analysis., John T. Cervini

Physics & Astronomy ETDs

A detailed description of a space qualified linear energy transfer (LET) spectrometer is presented. The Cellular Absorbed Dose Spectrometer (CADS) is a prototype instrument which was launched on March 17, 1969 into an elliptical orbit. Its purpose was to obtain the first successful LET measurements in space; and, thereby provide additional data to assess the biological hazards of the near earth space environment, especially during periods of in­creased solar activity.

The physical processes that take place in the CADS in­strument are discussed, and a definition of linear energy transfer is given, as well as its relation to dE/dx. The performance …

Multicultural Curriculum Training With Pre-Student Teachers In Language Arts., Martha Weidman Hubble

Teacher Education, Educational Leadership & Policy ETDs

Despite serious attempts to increase the educational success of minority groups, culturally diverse learners continue to fail to acquire the educational skills that allow for comforts afforded the majority culture. With stress on developing native and English language skills, important cultural aspects of minority groups' heritages have not been the primary concern. This study relates to two problems in multicultural education1 (1) the inability of teachers to relate to and understand. the culturally diverse learner, and (2) the dearth of teaching materials based on the minority group members' cultural heritages.

Randomly selected from 29 secondary education pre-student teachers in language …

Some Aspects Of The Role Of Usnic Acid In Forest Ecology, Yvonne C. Rogers

Biology ETDs

Usnea tillandsioides, an aboreal lichen, was observed in great numbers on spruce and fir at an elevation of 11,200 feet in the Sangre de Cristo Range, New Mexico. The amount of fallen lichen material per hectare was estimated. When usnic acid was extracted from lichen thallus, it was demonstrated that the quantity of usnic acid was less in summer lichens than in fall lichens. By soaking lichens in water, it was possible to extract a small amount of usnic acid. However, an examination of rainwater did not indicate that usnic acid was being leached from lichens by rainfall. Soil and …

Acid-Base Titrations In Sulfolane, Francine O. Lawrence

Chemistry and Chemical Biology ETDs

A study of the solvent effects of sulfolane (tetrahydrothiophene 1, 1-dioxide, tetramethylene sulfone) upon a series of acids and several bases has been conducted. A procedure is presented for purifying sulfolane which results in a solvent of very low water content (5 x 10^-4 M) and very few impurities, as shown by its cooling curve. Potentiometric and conductometric measurements of additions of acids and bases to purified sulfolane and of various acid-base titrations were made. The series of carboxylic acids included benzoic, orthomethoxybenzoic, and three different monochlorobenzoic acids. The bases investigated included sodium methoxide, pyridine, and diphenylguanidine. Interpretation of …

The Relationship Of Soil Temperature And Cytokinin Production In Aspen Invasion, Kristen R. Williams

Biology ETDs

Quaking aspen (Populus tremuloides Michx.) primarily reproduce by suckering (i.e., root sprouting). Numerous environmental variables have been suggested as causes of this phenomenon, the most notable of which is soil temperature. Studies demonstrating thermal regulation of sprouting indicate the involvement of growth hormones. The only class of hormones to elicit a response similar to sprouting is the cytokinins. Other hormones, no doubt, function in this process as well (e.g., auxins). To substantiate the idea that thermal regulation of sprouting is primarily a function of thermal regulation of cytokinin activity, and to determine the importance of other environmental factors in this …

Altitudinal Variation Of Chlorophyll Concentration And Reflectance Of The Bark Of Populus Tremuloides, William W. Covington

Biology ETDs

Chlorophyll concentration and reflectance of bark samples of Populus tremuloides Michx. growing at various elevations in the Sangre de Cristo mountain range of New Mexico indicate the appearance of greener barked trees at higher elevations is due to the reflectance characteristics of a bloom of dead periderm cells and not to increased chlorophyll concentrations. Chlorophyll concentration in aspen bark were, in fact, inversely correlated (p=.001) with altitude.

The higher concentration of chlorophyll at lower elevations is effectively masked by a white bloom which is also characteristic of exposed site trees. At higher elevations the bloom is yellow-brown and more translucent …

Continuous Wave Co2 Laser Degradation And Mass Spectrometric Analysis Of Organic Polymers, Stanley G. Coloff

Chemistry and Chemical Biology ETDs

Previous laser-mass spectrometer and laser-gas-chromatographic instruments for study of organic polymer degradation have used high power pulsed lasers (ruby, Nd-glass) which limit sample characterization due to extensive fragmentation. A new experimental technique has been developed for high temperature pyrolysis and rapid analysis of organic polymers. The experimental technique combines a low power continuous wave CO₂ laser for sample pyrolysis and a time-of-flight mass spectrometer to analyze degradation products. The laser built for use in this study was a continuous flow CO₂ gas-molecular laser excited by high voltage direct current with maximum power of 10 watts at a wavelength …
