An Ultrastructural Study Of Intramuscular Melanocytes In Pet/Wmr Mice, Charles August Gomer
An Ultrastructural Study Of Intramuscular Melanocytes In Pet/Wmr Mice, Charles August Gomer
Master's Theses
An examination of the lateral head of the gastrocnemius of the PET/Wn!.r mouse was made with an electron microscope. Cells of the perimysium and endomysium were described and the relationship of these cells to muscle cells was characterized. The relationship between melanocytes and muscle cells found in this strain was the major focus. Melanocytes were seen to be present in the perimysium and endomysium with the greatest concentration in the endomysium. Melanocytes of the perimysium appeared segregated from the adjacent tissue by fibroblasts,which surround ed the melanocytes with their cytoplasmic processes, a well as by collagen fibers. Melanocytes of the …
The Quality Of Storm Runoff From Different Kinds Of Land Surfaces In The Drainage Basin Of Westhampton Lake, Richmond, Virginia, Margaret Emil Coppedge
The Quality Of Storm Runoff From Different Kinds Of Land Surfaces In The Drainage Basin Of Westhampton Lake, Richmond, Virginia, Margaret Emil Coppedge
Master's Theses
Samples of runoff were collected during storms from four different areas within the drainage basin of Westhampton Lake, Richmond, Virginia, between October, 1977, and January, 1978. The areas were a residential area, concrete street gutter, asphalt parking lot, and broadleaf forest.
The samples were analyzed for pH, levels of reactive phosphate, nitrate, and turbidity, and their effects on the growth of algae from Westhampton Lake.
The pH of runoff from the residential area, gutter, and forest usually ranged between 6-7 and the parking lot usually ranged between 4-5. Levels of turbidity varied considerably between storms and areas. Runoff from the …
Lactate Dehydrogenase Isozyme Patterns From Five Species Of Snakes : Comparison Of Rattlesnake Vibratory Muscle With Body Epaxial Muscle, Cecil Bernard Cross
Lactate Dehydrogenase Isozyme Patterns From Five Species Of Snakes : Comparison Of Rattlesnake Vibratory Muscle With Body Epaxial Muscle, Cecil Bernard Cross
Master's Theses
Lactate dehydrogenase (LDH) isozyme patterns of seven tissues in each of five species of snakes are described from their polyacrylamide gel electrophoretic characteristics. The tissues examined included vibratory tail muscle, non vibratory tail muscle, body epaxial muscle, heart muscle, whole blood, liver and kidney. The species of snakes included Crotalus adamanteus, C. h. horridus, Agkistrodon piscivorus and Sistrurus miliarius barbouri from the family Crotalidae and Natrix taxispilota from the family Colubridae. These snakes show a decreasing continuum of tail vibratory activity, respectively, to N. taxispilota, which has a nonvibratory tail muscle.
Crotalus adamanteus, C. h. horridus and A. piscivorus have …
A Study Of The Self Report And Behavioral Differences Between High And Low Frequency Daters, Scott Daner
A Study Of The Self Report And Behavioral Differences Between High And Low Frequency Daters, Scott Daner
Master's Theses
Minimal dating, identified as a significant and relevant target problem, generally has been thought to result from either conditioned anxiety, negative self-evaluations, or social skills deficits. One hundred and thirty-eight subjects were screened and selected on the basis of high and low dating frequency and satisfaction with dating. Twenty-seven males and twenty-seven females who met the criteria participated in a "natural" social interaction. Subjects were paired in three groups: 11 high dating males and 16 high dating females, ten low dating males and ten low dating females, and 5 low dating men and 5 high dating women. Before and after …
Distribution Of Etheostoma Nigrum Rafinesque, Etheostoma Olmstedi Storer, And Their Introgressive Hybrid Populations In The James River Drainage, John Edward Clark
Distribution Of Etheostoma Nigrum Rafinesque, Etheostoma Olmstedi Storer, And Their Introgressive Hybrid Populations In The James River Drainage, John Edward Clark
Master's Theses
An analysis of proportional measurements and meristic characters of Etheostoma nigrum and E. olmstedi identified five populations within the James River drainage. Etheostoma nigrum inhabited the montane and piedmont areas through the Fall Line; E. o. atromaculatum was distributed throughout the tidal river and its lower tributaries; and E. o. olmstedi was restricted to creeks on the upper coastal plain. Appomattox River and Falling Creek contained introgressive hybrid populations with character frequency distributions intermediate to those of E. nigrum and E. o. olmstedi. It is proposed that E. nigrum probably entered these drainages through stream piracy on piedmont tributaries of …
Antipredative Function Of The Gelatinous Coating Of The Eggs Of The Frog, Rana Pipiens, Walter Stanley Jennings
Antipredative Function Of The Gelatinous Coating Of The Eggs Of The Frog, Rana Pipiens, Walter Stanley Jennings
Master's Theses
The eggs of Rana pipiens, the southern leopard frog, were offered in several forms to Lepomis macro chirus, the bluegill. The fish were offered random trial discrimination tests while in groups of one or five in 40 1 aquaria. L. macrochirus learned to make distinct discriminations and rejected fertilized and unfertilized egg masses, boiled egg masses, dried frog eggs and gelatin made with homogenated frog eggs. In contrast, Shrimp-el-etts, Shrimp-el-etts dyed black, gelatin made with peptone, and ovarian eggs were accept ed readily. The results suggest a protective function for the gelatinous coat: both physical and chemical . The chemical …
Ecology And Life History Of The Speckled Madtom, Noturus Leptacanthus (Ictaluridae), Kathleen E. Clark
Ecology And Life History Of The Speckled Madtom, Noturus Leptacanthus (Ictaluridae), Kathleen E. Clark
Master's Theses
This research represents an effort to understand the life history, strategy, and ecological relationships of Noturus leptacanthus. In particular I have tried to compare the combination of low fecundity, large egg size, parental car , and marked sexual dimorphism in leptacanthus with the patterns of these parameters in other ictalurid species.
