A Taxonomic Study Of Crotaphytus Collaris Between The Rio Grande And Colorado Rivers, William Ingram Iii, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

Little work has been done previously on the taxonomy of Crotaphytus collaris baileyi. This and the demonstration by Fitch and Tanner that C. c. baileyi is a heterogeneous grouping prompted the present study. Only the populations of the type material, the Upper Colorado River Basin, and the Chihuahuan Desert were studied. Multivariate, variance, canonical and discriminant analyses of external characters were performed, and pattern-coloration characters were examined on living specimens.

The results of the analyses show significance between all three populations. The discriminant functions distinguished between the populations with 80% reliability and patternal characters were discriminatory with near 100% reliability. …

A Revision Of Cryptantha Subgenus Oreocarya, Larry C. Higgins

Brigham Young University Science Bulletin, Biological Series

This study is a taxonomic revision of Cryptantha subgenus Oreocarya (Boraginaceae), together with descriptions of species, synonyms, distribution maps, and discussions. The present treatment recognizes fifty-seven species and fourteen varieties, all separated by means of a comprehensive key, A history of the group, along with a discussion of distribution, ecology, and phylogeny is presented. As a basis for the comparison of taxa much of the research has been concentrated on morphological variation in herbarium specimens. Particular attention has been directed to a study of pubescence types, branching patterns, flowers, calyces, and fruit. The herbarium research has been correlated with extensive …

Sturt Pea Hosts Collar Rot Fungus, M D. Marcley

Journal of the Department of Agriculture, Western Australia, Series 4

Evidence that Western Australia's Sturt Pea can be attacked by collar rot fungus suggests a reason for the occurrence of collar rot in places where the fungus should not survive.

At Carnarvon for instance, in spite of the hot, dry conditions, the collar rot fungus has been found on eggplants and Tuart trees.

Land Use In Wah Wah And Pine Valleys, Western Utah, Joseph R. Murdock, Stanley L. Welsh

Brigham Young University Science Bulletin, Biological Series

This is a review of the use of public lands in Wah Wah and Pine Valleys in western Utah for grazing of livestock, mining, and other private enterprises. The total area of the two valleys is approximately 1,440 square miles of which about 30 square miles are privately owned. From the time grazing of domestic livestock was initiated in the 1870's and 1880's until 1934, the land was free public domain and was grazed on a first-come, first-served basis. Passage of the Taylor Grazing Act in 1934 ended free use of public lands. Existing evidence indicates that by 1934 the …

Evolution Of The Iguanine Lizards (Sauria, Iguanidae) As Determined By Osteological And Myological Characters, David F. Avery, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The problem of phylogenic relationships within the iguanine phyletic line and the Madagascar iguanids have been investigated in order to explain the discontinuous distribution exhibited by the members of the family Iguanidae. Owing to inconclusive results from cytology and histological methods, the comparative morphology of the anterior osteology, myology, tongues, and hemipenes were used to determine relationships.

An examination of the above structures of the members of the iguanine phyletic lines and a comparison with the Madagascar iguanids indicates the following: ( 1 ) The Madagascar genera Chalarodon and Oplurus appear to be more closely related to each other than …

Freeze Branding For Cattle Identification On The Farm, C P. Mcdougall, R. C. Burking

Journal of the Department of Agriculture, Western Australia, Series 4

CATTLE identification presents many problems to beef and dairy farmers, and also to research workers. Although many methods are available no one simple method appears to be the complete answer.

This article describes the technique of freeze branding for cattle identification on the farm.

Observations On The Effects Of Flufenamic Acid On Cells In Vitro, Rick Truman Waterman

University of the Pacific Theses and Dissertations

The role of inflammation poses a number of interesting facets. Frequently it appears as a mechanism of defense: at other times it appears to present itself as a pathologic situation of unknown etiology. In neither case have the underlying mechanisms been fully identified. A variety of tissues can be involved, but when occurring as a pathology entity, it is more frequently observed in the synovial tissues. As a general rule, inflammation used as a defense mechanism in benign and self- limiting. This is not the case whore it become matter of pathology. It is here where mankind has looked for …

The Immediate Effect Of Swimming And Track Competition On Blood Ph Values, James B. Knott

Masters Theses

The purpose of the study was to investigate the changes associated with blood pH and different exercise work loads during competition. Finger tip blood samples (1 milliliter), were obtained from 33 male subjects from the varsity swimming and track teams of Eastern Illinois University. The samples were taken prior to exercise and between three and seven and one half minutes after cessation of the event. The blood samples were analyzed with a Radiometer Micro Blood pH Unit. The subjects were chosen on the basis of the events in which they competed. The swimming subjects competed in the 100, 200, 500, …

Glycogen Levels In Cardiac And Skeletal Muscle Of Rats Recovering From Exercise, Walter Talley Judd

Theses and Dissertations

In seeking answers to questions about how the human body functions under stressful situations, scientists, coaches, doctors, and athletes in general have all wondered about the role of exercise in the maintenance of good health. Good cardiovascular health, especially, is sought ardently, as it appears to be a major key to overall body fitness. Good cardiovascular health appears to go hand-in-hand with proper diet, proper rest, and proper exercise (1, 2).

The exercise phenomenon has attracted much attention and poses many questions. Just what is occurring when a person or an animal gets "in shape" by exercising. What bodily changes …

Two-, Three-, And Four-Particle Spatial Correlations Among Tertiary Cosmic Ray Muons, David D. Busath, R O. Stevenson

Faculty Publications

Showers of muons which result from interactions of primary cosmic rays high in the atmosphere appear deep underground as bundles of nearly parallel muons. For threshold energies of 1 TeV and arrival zenith angles of 45 degrees, those events having a small mean number of muons are described by a power law distribution in shower size having an exponent of ≅ -3.7 and a radial density distribution that decreases with distance R from the shower axis a little less rapidly than exp(-R/5.4 m). Comparison of new data on four muon spatial correlations in terms of the same phenomenology with data …
