The Vascular Flora Of The Kersey-Crump Creek Watershed, Hanover County, Virginia, Eddie Reeves Smith Jan 1981

The Vascular Flora Of The Kersey-Crump Creek Watershed, Hanover County, Virginia, Eddie Reeves Smith

Master's Theses

A floristic survey was conducted in the Kersey-Crump Creek watershed, Hanover County, Virginia from spring 1978 through summer 1980. This upper Coastal Plain area (42 km2) near the fall line yielded 514 species of vascular plants, representing 334 genera and 113 families. Four hundred and seventy-nine county records were established. Panax trifolium, colonizing a rich wooded creek bottom, was the only plant rare to Virginia. Voucher specimens are deposited in the herbaria of the University of Richmond, Virginia, and the College of William and Mary, Williamsburg, Virginia.

Reproductive And Mutagenic Effects Of 5-Thio-D-Glucose Injections In Male Mice, Mus Musculus, Icr Strain, Mary E. Mcmanaway Aug 1980

Reproductive And Mutagenic Effects Of 5-Thio-D-Glucose Injections In Male Mice, Mus Musculus, Icr Strain, Mary E. Mcmanaway

Master's Theses

Adult male ICR mice of proven fertility were intraperitoneally injected daily with 60 mg/kg of 5-thio-D-glucose for 28 days. Body weights of treated male mice were unaffected during the experimental period. Relative testicular weights were significantly reduced at 121 days after initial injections in 5-thio treated males, but no significant decrease was observed at 28 days.

Onset of sterility was estimated to occur at approximately 4 weeks and persisted for 5 to 6 weeks after cessation of treatment at which time fertility was restored.

Beginning with the first injections and continuing for 121 days, the males were mated with untreated …


The Effects Of Photoperiod And Melatonin Injections On The Reproductive System Of Male Mice, Mus Musculus, Icr Strain, Margaret Ann Shugart Aug 1980

The Effects Of Photoperiod And Melatonin Injections On The Reproductive System Of Male Mice, Mus Musculus, Icr Strain, Margaret Ann Shugart

Master's Theses

The reproductive effects of long (24L:OD), natural (14L:lOD), and short (1L:23D) photoperiods were studied in the male mouse, Mus musculus, ICR strain. One third of the mice in each photoperiodic regimen were sacrificed after 45 days. Half of the remaining mice in each regimen received daily melatonin (5-methoxy-N-acetyl tryptamine) injections for 45 additional days. Body weights, testicular and accessory sex organ weights were measured and microscopic examinations of the testes were made. Plasma testosterone levels were determined using radioimmunoassay. Other organ (pituitary, kidney, adrenal, thymus, thyroid) weights were also obtained.

Seasonal Sexual Cycle Of Nerodia Taxispilota (Serpentes: Colubridae) At The Northeastern Edge Of Its Range, David Roland White Jan 1980

Seasonal Sexual Cycle Of Nerodia Taxispilota (Serpentes: Colubridae) At The Northeastern Edge Of Its Range, David Roland White

Master's Theses

The seasonality of the sexual cycle of Nerodia taxispilota at the northeastern edge of its range was elucidated from specimens collected over a two-year period (1978-1979) from the Appomattox River near Hopewell, Virginia. The investigation centered on morphological changes in the testis of males and vitellogenesis and embryo development in females. Related reproductive parameters also studied were body size differences, seasonal sex ratios, comparative tail lengths, and tail mutilation.

Male and female cycles closely resembled those of other temperate zone colubrids. Spermatogenesis began in May and testis size peaked in late August. Testis length showed a time lag when compared …

Growth And Food Habits Of Micropterus Salmoides In Westhampton Lake, Richmond, Virginia, Charles H. Rawls Jr. Aug 1979

Growth And Food Habits Of Micropterus Salmoides In Westhampton Lake, Richmond, Virginia, Charles H. Rawls Jr.

Master's Theses

Age, growth, and food habits of the population of Micropterus salmoides (largemouth bass) in Westhampton Lake were studied from September to November 1978. Two year classes (0 and I) were identified by determining numbers of annuli on the scales of the fish. Growth data indicated that the bass attain a size of 254 mm (10 in.) near the end of their second summer. The length-weight relationship was log W = -4.6829 + 2.9153 log TL. The Fulton condition factor for the population was 1.40. Food habits were described by numerical and frequency of occurrence methods. Young of the year sunfish …


The Interacting Effects Of Tetraiodothyronine And Epinephrine On The Activities Of Na+ + K+ -Dependent Adenosine Triphosphatase, Hexokinase And Pyruvate Kinase In The Cardiac Tissue Of White Rats, Timothy Joseph Dietrick Aug 1979

The Interacting Effects Of Tetraiodothyronine And Epinephrine On The Activities Of Na+ + K+ -Dependent Adenosine Triphosphatase, Hexokinase And Pyruvate Kinase In The Cardiac Tissue Of White Rats, Timothy Joseph Dietrick

Master's Theses

The interacting effects of tetraiodothyronine (T4) and epi- nephrine on Na++K+-dependent ATPase, hexokinase, and pyruvate kinase in cardiac tissue of white rats were investigated in an attempt to elucidate the hormonal regulation of heart metabolism. Previous evidence has shown that 90% of the increase in oxygen consumption exhibited by hyperthyroid rats was due to an activation of Na++K+- dependent ATPase. In addition, hypothyroidism in sheep was re­ ported to lower cardiac Na++K+-dependent ATPase activity as well as 8-adrenergic binding sites for epinephrine. As T4 and epinephrine enhance carbohydrate metabolism, hexokinase and pyruvate kinase, two essentially irreversible glycolytic enzymes, were also …
