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. …

Type Appraisal: I. Effects Of Age And Stage-Of-Lactation On Type Ratings, H. D. Norman

Department of Animal Science: Faculty Publications

Dairy cattle type appraisal data were examined to determine whether body and udder conformation and management ratings were affected by age and period of lactation at appraisal. Data were collected from 1961 to 1968 from 188 herds having over 23,000 Holstein type appraisals. The body and udder traits were scored by scheduled appraisers, and the management traits were coded by each dairyman. Some of the 35 original traits were composed of more than one descriptive characteristic and, as a result, 49 renamed traits were derived from these.

A model was selected that considered years and herds as well as cow …

Cause And Control Of A Common Market Disease Of Lettuce, William Palmore

Masters Theses & Specialist Projects

Head lettuce, Lactuta sativa var. capitata, is susceptible to a number of economically important diseases, the most frequent being russet spot, rib discoloration, and vascular browning (28), which have been shown by Ceponis and Friedman (7) to be caused by Pseudomonas marginalis. Pseudomonads are common plant pathogens and cause such diseases as halo blight in beans (20), bacterial blight in soybeans (20), and bacterial wilt of the bird-of-paradise (27) and tobacco (24).

Plants that develop symptoms similar to russet of lettuce are oats, infected by Pseudomonas cichorii, and tobacco infected with Pseudomonas tobaci (34). In general, russet symptoms …

A Replacement Prosthesis For The Hip: A Preliminary Report, H. M. Frost, E. R. Guise

Henry Ford Hospital Medical Journal

Because of theoretical as well as practical difficulty in the total hip endoprostheses available to orthopaedic surgeons at the present time, an anlysis of the present and potential difficulties reveals that substitution of a roller-bearing for the present slider-bearing prosthesis and the establishment of a larger end-bearing surface on the acetabular side would be of benefit. Thus, the Ring prosthesis was re-designed to satisfy these hopes. A modification of the Ring's approach gives complete acetabular exposure and control of the prosthetic insertion. This is a preliminary report describing the design modifications of a prosthesis, presently under investigation, and illustrated by …

The Somatic Chromosomes Of Some North American Marmots (Sciuridae), With Remarks On The Relationships Of Marmota Browerii Hall And Gilmore, Robert L. Rausch, Virginia R. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Karyotypes are defined for two nearctic species of marmots, Marmota olympus (2n = 40) and M. vancouverensis (2n = 42), and supplemental information is included on the karyotypes of M. flaviventris, M. monax ochracea, and M. marmota. The six North American species of Marmota (NF = 66) comprise a distinct group as compared with the middle Asian species (NF = 70) for which the karyotypes are known. Karyologic findings and zoogeographic evidence based upon the distribution of two nearctic species of host-specific cestodes indicate that M. broweri, in northern Alaska, is a pre-Würm relict. Its affinities …

Bulletin No 3768 - Submitting Plants For Disease Identification, M D. Marcley

Bulletins - 3000 - 3999

THERE are several important points to remember when submitting plant material for disease identification by the Department of Agriculture's Plant Pathology Branch.

Firstly it is very important to collect a suitable sample because it is very difficult to determine the cause of a plant disease by looking at a completely dead plant. The sample should include the entire plant (before it is completely dead) including roots and soil. Then all the effects of the disease can be seen. For example leaf yellowing, dead areas of the stem, collar rot, root rot, eelworm damage, and disease of the water and food …

Morphological Variation In Stenoderma Rufum, J, Knox Jones Jr., Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

For more than 100 years, the red fruit-eating bat, Stenoderma rufum Desmarest, 1820, was known only by a specimen of unknown geographic provenience. Anthony ( 1918, 1925) rediscovered Stenoderma in Puerto Rican cave deposits, but the first living specimens to be reported since the original description were taken on St. John in the Virgin Islands (Hall and Bee, 1960). Subsequently, Tamsitt and Valdivieso (1966) recorded living representatives from Puerto Rico-from a population later named and described as a distinctive subspecies, Stenoderma rufum darioi, by Hall and Tamsitt (1968). The latter authors also reported a specimen of S. r. rufum …

Immunologic Enhancement Of Murine Sarcoma I Tumor System, Fung-Win Shen

Biology ETDs

The purpose of this project was to study the mechanism of imnunologic enhancement in the mouse a t the cellular level. The Sarcoma I (Sal, H-2^a) murine tumor system was employed as the model for this study. Sal, indigenous to the A/J (H-2^a) strain of mouse, grows progressively in its syngeneic host but is rejected by non-H-2a mice. However, the SaI tumor can be induced to grow progressively in C57BL/KsJ (Ks, H-2d) mice by passive administration of Ks anti-Sal serum at the time of Sal tumor implantation. This phenomenon is termed immunologic enhancement. Hereafter, mice pretreated …

Molecular Weight Distribution Of Proteins Synthesized In Single, Identified Neurons Of Aplysia, David L. Wilson

Biology Articles and Papers

Parietovisceral ganglia from Aplysia californica were incubated in medium containing leucine-³H. Single, identified nerve cell somas were isolated from the ganglia, and their proteins extracted and separated by electrophoresis on 5% SDS-polyacrylamide gels. The distribution of total or newly synthesized proteins from the single neurons was determined by staining or slicing and liquid scintillation counting of the gels. Experiments showed that: (a) a number of proteins were being synthesized in abundance in the nerve cells; (b) different, identified neurons showed reproducibly different labeling patterns in the gels; (c) cells R2 and R15, …

Grain Sorghum In The Ord Valley : Three Crops A Year?, P J. May

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

High temperatures and ample irrigation water allow grain sorghum to be grown throughout the year on the Ord River Irrigation Area, and observations in 1969-70 indicated that it may be possible in this area to produce three crops in one year from one planting, by ratoon cropping.

This article describes the technique and discusses its possibilities on the Ord.

The sorghum midge, one of the worst pests of sorghum, could well make ratoon cropping impossible, but the midge has not yet been seen in this area.
