Mammals Of Mount Taylor, Valencia County, New Mexico, Eugene E. Schroeder

Biology ETDs

During the summer of 1960, three months were spent in making a comprehensive study of the kinds and ecological distribution of native mammals in and above the Transition Zone on Mount Taylor of Valencia County, New Mexico.

Mount Taylor, and old volcanic pile, rises 11,301 feet above sea level. Three boreal life zones, the Transition, Canadian, and Hudsonian were assigned to Mount Taylor.

Small mammals were collected by two sampling methods, quadrant and line trapping. However, mist nets were used for capturing bats. Quadrants were placed in various plant communities for three successive nights. Numbers and kinds of mammals recorded …

Geographic Variation Of The Hispid Cotton Rat In New Mexico, A.L. Gennaro

Biology ETDs

A total of 520 cotton rats, Sigmodon hispidus, was examined to determine the kind and amount of geographic variation of these animals in New Mexico.

The distributional history of Sigmodon hispidus in New Mexico may be revealed by a relationship between color variation of these animals and soil color of areas from which these animals were taken. This relationship suggests, firstly, that Sigmodon hispidus has occupied the southern Rio Grande Valley for a longer period of time than it has areas east of the Rio Grande Valley, and secondly, that Sigmodon hispidus has only recently occupied the Deming Plain. …

Serum Protein Electrophoresis Study Of Citellus Species, Rondal E. Bell

Biology ETDs

The systematic separation of species of the genus Citellus is based principally on external and cranial features. These features are well known in most of the genus, but there has been considerable uncertainty concerning the subgeneric allocation and a more comprehensive study is needed.

Distribution And Variation Of The Mexican Vole In New Mexico, Clyde Jones

Biology ETDs

The purpose of this investigation is to describe kind and amount of geographic variation of Microtus mexicanus, a grass-inhabiting vole, in New Mexico and some adjacent areas. It was found that environmental conditions, such as amount of moisture, and amount and type of vegatational cover, as well as ecological competition with similar species, seemingly affect geographic variation among populations of M. mexicanus. Among the populations studied, geographic variation in color and size of the auditory bullae is more apparent than geographic variation in other features.

A Distributional Check-List Of New Mexican Mammals, Arthur H. Harris

Biology ETDs

Vernon Bailey's Mammals of New Mexico is not a satisfactory source of data for many studies which directly or indirectly involve distributions of mammals within New Mexico. The present work is an attempt to provide such a source--to bring together in usable form all published records of occurrence within the state for each species of mammal that is known to occur in New Mexico and also to make available such unpublished records as are present in the University of New Mexico Collection of Vertebrates. Some additional information on names, life-zone preferences, and subspecies to be found within the state has …

The Development Of The Weberian Ossicles In Pantosteus Plebius, John Lawrence Butler

Biology ETDs

The Weberian apparatus, which was first described by Weber in 1820, is characteristic of the largest order of freshwater fishes, the Ostariophysi, a group that includes, forty-two families, among which are the minnows, suckers, siluroids, and characids. The apparatus of the family Catostomidae, the suckers, is one of the more complex because the anterior vertebrae are more highly modified than in most other groups. Although the suckers have a more complex form of apparatus, they have received comparatively little study, and this is the first developmental investigation of the Weberian ossicles of any catostomid.

The Distribution And Ecology Of The Hispid And Least Cotton Rat (Genus Sigmodon) In New Mexico, John S. Mohlhenrich

Biology ETDs

Two species of cotton rats, Sigmodon minimus Mearns (least cotton rat) and S. hispidus Baird (hispid cotton rat), occur in the Rio Grande Valley of New Mexico. The northernmost published record-station for S. hispidus is near Scorro, Scorro County ( Bailey, 1931: 167), and that S. minimus is near Isleta, Bernalillo County (Ivey, 1947: 498 and map). When recent field work by the author revealed the presence of both species in the Rio Grande Valley north of these published record-stations the problem arose whether the range extensions were the result of a recent northward extension of the range of the …

A Bio-Assay And Histochemical Study Of Antidiuretic Hormone In Normal And Adrenalectomized Rats, Jean Kautz Lauber

Biology ETDs

The role of neurohypophyseal hormone vasopressin in water and electrolyte regulation has been of interest to both physiologists and clinicians. This interest has been stimulated recently by identification of the chemical structure and synthesis of this polypeptide hormone by duVigneaud and his co-workers, an accomplishment which won for duVigneaud the Nobel Prize in 1955.

Studies On The Microcrustacea Of Three Montane Lakes In Glacier National Park, Montana, Robert O. Megard

Biology ETDs

Grinnell Lake, Lake Josephine, and Swiftcurrent Lake, at an elevation of approximately 5,000 feet in northwestern Montana, are comparable with lakes in the montane zone defined by Pennak for lakes at elevations between 8,200 feet and 10,500 feet in the Rocky Mountains of northern Colorado. Five species of Copepoda, six Cladocera, and four Ostracoda were collected in the lakes studied. The population of microcrustacea in these lakes was most dense in or slightly above the masses of rooted aquatic vegetation growing to a height of six to 10 inches above the bottom wherever the water was between three feet and …

A Distributional And Taxonomic Study Of Ratibida Columnifera Var. Columnifera, Ratiba Columnifera Var. Pucherrima, And Their Hybrids In New Mexico, Walter W. Marshall

Biology ETDs

The classification and distribution of Ratibida columnifera var. columnifera Woot. and Standl. and R. columnifera var. pulcherrima (DC.) Woot. and Standl. are complex. Some floras list R. columnifera var. pulcherrima as a purple colored form or variety of the species while other authors refer to this taxon as a separate species of Ratibida. The purpose of this study is to clarify the taxonomic status of the two forms by determining and differences in morphology, distribution, taxonomy, and ecology.

An attempt has been made to determine the route by which R. columnifera columnifera and R. columnifera pulcherrima were distributed. After this …

Use Of The Antibiotics, Streptomycin And Terramycin, As Growth Stimulants For Orchid Seedlings, Margaret W. O'Neill

Biology ETDs

Antibiotics first came to the public's attention in 1945, when penicillin and streptomycin were released by the United States government to fight human diseases. Later, other antibiotics were released and experimental work was done on control of plant and animal diseases. By 1948 plant pathologists found that certain plant diseases such as walnut blight, tomato and pepper bacterial spot, soft rot, cucumber, downy mildew, chrysanthemum bacterial wilt, and lilac bacterial blight could be controlled by antibiotics.

The Effect Of Adrenalectomy And Cortisone Acetate On Experimental Liver Cancer, Richard A. Heise

An attempt was made in this study to determine the completeness of adrenalectomy and effect in conjunction with cortisone acetate and/or desoxycorticosterone trimethylacetate (DCT) on the development of liver tumors in rats fed 3'-methyl-4-dimethylaminoazobenzene (3'-Me-DAB)

The Effects Of Adrenal Steroids On Electrolyte And Water Balance In Force-Fed Intact Rats, Emma Romero

Biology ETDs

During the past decade a number of biological and clinical investigations have been concerned with the inhibitory effects of 11-oxy and 17-hydroxy steroids on water and sodium excretion. However, it is recognized by many investigators that such steroids may act either to inhibit or enhance water and sodium excretion, the results obtained depending upon experimental circumstances.

A Survey Of Serum Enzymes As A Possible Index Of Radiation Injury, Lora Belle Hughes

Biology ETDs

Early changes in the serum concentrations of glutamic-oxalacetic transaminase, glutamic-pyruvic transaminase, lactic dehydrogenase, and malic dehydrogenase were determined in young adult rats following exposures to sublethal, midlethal, and supralethal doses of X-irradiation, treatment with hepatotoxic agents or opiates, and sequential administration of both X-irradiation and the hepatotoxins. Changes in serum enzyme content were also determined in a series of 38 rhesus monkeys within 30 minutes after exposure to sublethal doses of fission neutrons.

Relatively small increases in serum enzyme concentration, detectable within 1 to 6 hours after whole body X-irradiation, were greatly exaggerated by prior treatment of the test animals …

The Effects Of Desoxycorticosterone Trimethylacetate, Desoxycorticosterone Acetate, Cortisone Acetate, And Adrenalectomy On The Liver Succinoxidase And Glutamic Dehydrogenase Activity Of Rats Fed 3'-Methyl-4-Dimethylaminoazobenzene (3'-Me-Dab), John P. Davanzo

Biology ETDs

Experimental production of liver cancer by means of azo dyes is a standardized and convenient method for study of the cancer problem. The rat is the animal of choice for this type of experimentation because this animal is readily susceptible to liver carcinogenesis upon being fed azo dyes. Mice are only partially susceptible and rabbits and guinea pigs will not develop cancer of the liver by ingestion of the azo dyes (E. C. Miller and J. A. Miller, 1947, p.473). The liver, likewise, is an appropriate organ for study. Enzymologists and cytologists today regard the liver cell as the best …

The Collembola Of New Mexico With Especial Reference To The North-Central Part Of The State, Harold George Scott

Biology ETDs

The is one of the first faunistic studies to be completed in New Mexico and one of the first comprehensive analyses of the ecological distribution of the species of Collembola in as large and varied an area as New Mexico. One hundred fifty-two Collembola species, of which 24 are described as new, are recorded from New Mexico. In addition four species, of which one is described as new, are recorded for the first time from Colorado. Prior to the present study, only four species of Collembola were recorded from New Mexico.

The Effect Of Adrenal Steroid Hormones On The Protein Content Of Tumorous Livers, Duncan W. Martin

Biology ETDs

Protein is basic to the structure and function of protoplasm. Enzyme systems which regulate the rate of cellular reactions are primarily composed of protein and many of these enzymatic systems influence the metabolism of less specialized proteins that form the major structural material of protoplasm. It is believed that experimental procedures which modify protein composition of cells may also influence the activity of intra-cellular enzymes. In experimental live cancer, it has been shown that the activities of a number of oxidative enzymes are modified as the carcinogenic process proceeds (Richmond, 1955, p.38). Furthermore, it has been demonstrated that endocrine function …

A Taxonomic And Ecological Study Of The Ants On The Campus Of The University Of New Mexico, Tad S. Clements

Biology ETDs

This thesis attempts to indicate some of the ways in which the ants of the campus of the University of New Mexico affect man within the small area of the campus. However, my purpose of doing the study has not been strictly limited by practical considerations. Until now, no systematic study has been made of the Formicidae of the University of New Mexico Campus. Since the habitats produced artificially by man on the University of New Mexico Campus have resulted in favoring certain species of ants not found by the writer elsewhere in the region, the present study is valuable.

Respiration, Succinoxidase And D-Amino Acid Oxidase Studies On Livers From Rats Fed The Hepatic Carcinogens 4-Dimethylaminoazobenzene (Dab) And 3(1)-Methyl-4-Dimethylaminoazobenzene(3(1)-Me-Dab), Donald R. Richmond

Biology ETDs

In 1933, Japanese workers produced liver cancer in rats by feeding o-amino-azo-toluene (cited by Rusch, et al. 1945, p.267). The carcinogenecity of the azo dyes became especially important since the incidence of these liver tumors varied profoundly with the composition of the diet in which it was given. Similar variations due to the diet had not been orbserved with the types of carcinogens. From further studies, in which known compenents were added to purified diets, both protective (anticarcinogenic) and augmenting (procarcinogenic) influences could be ascribed to individual components.

The Minimal Nutritional Requirements Of Several Strains Of Shigella Dysenteriae 1, Roy M. Johnson

Biology ETDs

The study of bacterial nutrition is fundamental to an understanding of the physiological aspects of microorganisms. The advances made in biochemical research during the past few decades have permitted the employment of synthetic media for a large number of microorganisms previously able to grow only on complex, ill-defined media. In turn, microorganisma have become a valuable tool of the biochemist for the assay of vitamins and growth factors. These combined efforts of the biochemist and the microbiologist have advanced the entire field of physiology applicable to all organisms.
