The Effects Of Photoperiod And Melatonin Injections On The Reproductive System Of Pinealectomized Male Mice Mus Musculus, Icr Strain, John Earnest Constantine
The Effects Of Photoperiod And Melatonin Injections On The Reproductive System Of Pinealectomized Male Mice Mus Musculus, Icr Strain, John Earnest Constantine
Master's Theses
One hundred two male mice , Mus musculus, ICR strain, age four weeks, were obtained. Fifty-one mice were pinealectomized and 51 were sham operated. The animals were divided into three photoperiod groups: 1.5L:22.5D, 14L:10D, 24L; 0D. The mice were subcutaneously injected daily with 10 ug melatonin or control solution from post-operative day J to post-operative day 60, On post-operative day 60 representatives of each photo period-surgery-injection regimen were paired with females. The remaining animals were killed and several organs were removed and weighed, Melatonin injections were progonadal in pinealectomized mice and inhibitory in sham mice in several instances. Histological examination …
The Spatial Distribution Of Phytoplankton In Westhampton Lake, Richmond, Virginia, James William Newlin
The Spatial Distribution Of Phytoplankton In Westhampton Lake, Richmond, Virginia, James William Newlin
Master's Theses
The hypothesis is that spatial distributions of phytoplankton standing crop and photosynthetic capacity in Westhampton Lake are homogeneous was tested. Distributions were analyzed with respect to horizontal and vertical planes separately and combined. The study was divided into three time period: 1) late summer stratification, 2) early fall mixing, and 3) fall turnover, based on isothermal lines of the lake at the deepest station. Phytoplankton standing crop was measured by spectrophotometric and fluorometric methods. The photosynthetic capacity was measured flurometrically. Combined horizontal and vertical spatial distribution of standing crop was clumped for the entire lake and during each time period. …
Population Stability Of Three Species Of Zooplankton In Westhampton Lake, Richmond, Virginia, James Christopher Conyers
Population Stability Of Three Species Of Zooplankton In Westhampton Lake, Richmond, Virginia, James Christopher Conyers
Master's Theses
Populations of zooplankton, Keratella cochlea's (Rotifera) Bosmina longirostris (Cladocera), and Mesocyclopsedax (Copepoda) were sampled in Westhampton Lake from June 30 to December 22, 1978. Population densities were estimated over time and analyzed for stability relative to the occurrence of rainfall. Two aspects of stability were used for analysis and given operational definitions as follows: Resistance - a population was resistant if its density was not more variable during periods of rain compared with periods of little or no rain; Persistence - a population was persistent if its density during periods of rain was not different from its density in periods …

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