The Status Of The Common Crow Corvus Brachyrhynchos Brehm In The Great Basin, Gerald Low Richards

Theses and Dissertations

Due to a lack of taxonomic and distributional information concerning the Common Crow Corvus brachryhynchos Brehm inhabiting the Great Basin of North America, Johnston (1961) in one of the most recent revisions on crows, was unable to include this area in his work. Between 1965 and 1967, field trips were taken throughout the Great Basin to secure specims, and to determine to what extent the area was being utilized by crows. Ecological information such as habitat prference, nesting behavior, and interactions with other species was collected where possible. Forty-eight birds were collected from the Great Basin. From a comparison of …

Investigation Of Nitrogen Fixation By Three Species Of Lichen, Dortha Maloy Robinson

Theses and Dissertations

One species of lichen from each of three different families (Collema wyomingensis , Caloplaca elegans (Link)T. Fries, and Parmelia molliuscula Ach.) was studied to determine whether or not these lichens can fix atmospheric nitrogen. Samples of these three lichens were collected in the early spring of 1967. Samples of each species were placed in 20-ml glass tubes which contained 5 ml of glass wool saturated with 0.5 M nitrogen-free Hoaglands nutrient solution. These tubes were sealed by heat onto a gas manifold system and evacuated. An N15- enriched atmosphere (22 atoms % N15) was introduced into the tubes from the …

The ranges of the three species overlap in an area along the eastern coast of the United States from central North Carolina to near Jacksonville, Florida. The flounders are closely related and unless the pig­ment pattern …

A Study Of Hybridization And Behavioral Characters In Percina Notogramma (Rany And Hubbs) And Percina Peltata (Stauffer), Family Percidae, Jules J. Loos

Master's Theses

In view of the close phylogenetic relationship between the two sym­patric species of darters, Percina notogramma (Raney and Hubbs) and Percina peltata (Stauffer), placed in the subgenus Alvordius by Bailey and Gosline (1955), it is of interest to compare them in more detail than has been done in the past. Percina notograrnma occurs only in the Chesapeake Drainage in Virginia, Maryland and West Virginia whereas P. peltata ranges from Virginia to New York. Adequate comparisons of their external. morphological characters have been presented by Raney and Hubbs (1948) in their original description of P. notogramma. Supplementary data were provided by …

Electrical Response Of Frog Skin Epidermis To Sodium Ions, James H. Martin

Master's Theses

Presently, the theory is held that the total frog skin potential (P.D.) is generated within the epidermis at two borders, the "outer border" and the "inner border, " which are said to be specifically permeable to Na⁺ and K⁺, respec­tively. This thesis concerns itself only with the electrical response of the "outer border" to varying Na⁺ concentrations in the solutions at the epidermis, [Na⁺]_o. Contrary to expectation from the Nernst equation, the P.D. changes by only 17 to 35 mV, instead of theoretically 58 mV upon a 10 fold change in [Na …

Respiratory Activity Of Vibratory, Tail Epaxial And Midbody Expaxial Muscle In Crotalus Horridus, Aqkistrodon Contortrix, And Thamophis Sirtalis., James E. Forbes

Master's Theses

The purpose of this study was to determine if the muscles associated with tail vibration in snakes are physiologically specialized for vibration. Timber rattle­ snakes (Crotalus horridus) , copperheads (Agkistrodon contortrix) and garter snakes (Thamnophis sirtalis) were used. The copperhead represented a species which vibrates its tail but has no vibratory apparatus comparable to that of the rattlesnake. The garter snake does not vibrate its tail. A comparison of respiratory activities was made between the vibratory and tail epaxial muscle and the mid­ body epaxial muscle within and between the three species. Oxygen consumption of teased muscle fibers and muscle …

Distribution Of Eggs And Leaf Mines Of Choristoneura Houstonana (Lepidoptera: Tortricidae) Attacking Eastern Red Cedar, Juniperus Virginiana, Elvis A. Heinrichs

Department of Entomology: Faculty Publications

Cedar at Larned, Kansas, appeared to be more severely damaged in the upper and southern portions of the trees. There was a significant difference, in numbers of eggs and leaf mines, between the upper and lower halves and between compass directions; the upper and southern portions of the trees being most highly infested.

Choristoneura houstonana (Grote) is a pest of eastern red cedar, Juniperus virginiana, grown as a home landscape ornamental in shelter belts and windbreaks in western Kansas. It has been present for many years but the first reliable record in Kansas was in 1964, when it was sent …

Aspects Of The Life History And Distribution Of The Jemez Mountains Salamander, Plethodon Neomexicanus, Douglas P. Reagan

Biology ETDs

Plethodon neomexicanus, the Jemez Mountains Salamander, is endemic to the Jemez Mountains where it is restricted to talus slopes that are forested and shaded and that have suitable conditions of moisture and temperature. During the summer of 1966 four new localities were found, yielding information on the combination of factors which favor the presence of this salamander. Its habitat is at elevations of 7900-9200 ft within the upper montane forest of the Rocky Mountains. In the Jemez Mountains this forest exists at these elevations only on shaded north-facing slopes or in deep, shaded canyons. The presence of volcanic talus provides …

The Effects Of A Nerve Growth-Promoting Protein On The Integument Of Pet Mice, Craig Bauman Satterlee

Master's Theses

A factor which specifically stimulates the growth of sensory and sympathetic nerve cells has been under investigation for a number of years. This factor, originally isolated in 1951, from mouse sarcomas 37 and 180, was named the "nerve growth factor". Its action was first shown in vivo by inoculating the sarcoma into chick embryos and subsequently in vitro by culturing chick ganglia and mouse sarcoma together. In the years immediately following the initial discovery, much more potent sources of NGF were found in the salivary glands and salivary secretions of a variety of species. These include rattle snake venom, and …

The Nitrogen Nutrition Of Emmonsia (Moniliales, Aleurismaceae), Gary L. Bradley

Loma Linda University Electronic Theses, Dissertations & Projects

The questions posed in this research concerned both the comparison of the nitrogen nutrition between Emmonsia parva and Emmonsia crescens and the comparative nitrogen utilization within the species. This fungus is a parasite with a rather uncomplicated life-cycle. Thus it lends itself well to study of the host-parasite relationship at the molecular level. This research contributes toward that long-range goal.

Five replicate floating cultures of each species were grown in 125 ml Erlenmeyer flasks containing a chemically defined basal medium plus one of the 29 nitrogen sources tested. Utilization of a particular source was determined by dry weight. The results …

Vegetable Entrees In Nitrogen Balance And Obesity Studies, Gloria Tyndall

Loma Linda University Electronic Theses, Dissertations & Projects

The first study was designed to evaluate by the nitrogen balance method the protein quality of a pure-vegetarian diet containing about 6 grams of nitrogen per day. The group as a whole maintained nitrogen equilibrium the average being - 0.11 grams of nitrogen per day. Two subjects were not in nitrogen balance, however, factors other than diet may have contributed to these results and are discussed in the thesis. Hemoglobin, serum cholesterol and total serum proteins did not change significantly during the study. The average true digestibility of 5 of the subjects was 85 percent. It was concluded that this …

Carbon Dioxide Fixation In Schistosoma Mansoni, Clint Earl Carter

Loma Linda University Electronic Theses, Dissertations & Projects

Adults of the blood fluke Schistosoma mansoni were perfused from the hepatic portal system of CF1 female mice sixty to seventy days post infection. The worms were then incubated in Eagle’s minimal essential medium with glutamate and 0.03 mg/100 ml of nonlabelled aspartic acid. To this medium was added 10 μc of either NaH¹⁴0₃, glucose-UC¹⁴ or aspartate-4-C¹⁴. The worms were found to fix carbon from the NaH¹⁴0₃ and to incorporate the glucose and aspartate. The amount of activity recovered in five different chemical fractions after two hours incubation was determined …

Nutritional Relationship Between The Copepod Parasite Charopinus Dentatus (Wilson) (Lernaeopodidae) And The Skate Host, Raja Binoculata Girard, Donald W. Rigby

Loma Linda University Electronic Theses, Dissertations & Projects

Of 1,798 parasitic copepods, Charopinus dentatus (Wilson), collected from the skate host, Raja, binoculata Girard, 1,615 (89.87.) were obtained from the mucosa lining the mouth and pharynx. None were collected from the gill filaments. Host tissue damage was not seen grossly or microscopically around the attached parasite nor did the gut contents of female parasites give evidence microscopically or chemically that they are blood feeders. Green material from the gut of female parasites was made up of cell-like structures occurring singly and in clumps. Spectrophotometrically this material demonstrated spectral maxima (670, 410 'FM) similar to maxima of degradative products of …

Mandibular And Alveolar Growth In Dog Following Infusion Of 5-Fluorouricil, Richard D. Pfeiffer

Loma Linda University Electronic Theses, Dissertations & Projects

The action of a chemotherapeutic agent as a tool in studying its effect upon a primary growth center, the mandibular condyle, was investigated. So far as can be ascertained, no studies have been reported where these growth sites have been eliminated or modified by the use of chemotherapeutic growth inhibitors.

Observation of mandibular and alveolar growth following the infusion into the left external carotid artery of a cancer chemotherapeutic agent, 5-Fluorouricil (Roach-Hoffman), was noted. Comparisons were made between the infused and the uninfused sides of the mandible observing gross growth changes.

Four dogs, aged 75 days, were infused with varying …
