Using Gis And Land Use Data To Select Candidate Reference Sites For Stream Bioassessment, John Robert Olson
Using Gis And Land Use Data To Select Candidate Reference Sites For Stream Bioassessment, John Robert Olson
Theses and Dissertations
GIS was used to select candidate reference sites in Georgia to characterize the reference condition by sub-ecoregion for a rapid bioassessment of streams statewide. Instead of relying on best professional judgment or previous knowledge of a limited number of sites, we performed an objective evaluation of cumulative impact on all catchments using land use data sets. These included road and impoundment data from DLGs and Multi-Resolution Land use Consortium data. Land use impairment was measured as percentages of forest, urban, pasture, row crops, and barren area for both the entire catchment and for 10, 40, and 130-m riparian buffers, road …
Impact Of A Historical Translocation On Populations Of White-Tailed Deer Odocoileus Virginianus, Nathan Kendall Boddie
Impact Of A Historical Translocation On Populations Of White-Tailed Deer Odocoileus Virginianus, Nathan Kendall Boddie
Theses and Dissertations
Randomly amplified polymorphic DNA (RAPD) analysis was used to study the impact of a historical translocation event on populations of white-tailed deer in Georgia. The technique may also serve as a model by which management practices for other rare species can be studied. Populations from an original translocation source in Wisconsin, another Wisconsin population, and three populations in Georgia were sampled during management hunts. RAPD PCR was used to produce a genetic fingerprint for individuals of each population. Resulting band data were analyzed using PHYLIP genetic analysis software. A consensus tree of 100 bootstrapped replicates showed significant similarity between Georgia …
The Distribution Of Macroinvertebrates Along The Impounded Middle Chattahoochee River, Page Jones
The Distribution Of Macroinvertebrates Along The Impounded Middle Chattahoochee River, Page Jones
Theses and Dissertations
This project was part of a series of investigations designed by the Columbus (Georgia) Water Works to evaluate composition of the macroinvertebrate fauna of the mainstem of the middle Chattahoochee River, as well as its tributaries. An additional objective of the survey was to characterize impacts of storm events on urban streams and the mainstem of the Chattahoochee River. This portion of the study was designed to assess composition of benthic communites of an urbanized river in which flow regime is altered by a series of impoundments. Nine dams currently regulate flow of the mainstem of the middle reach of …
An All-To-All Multicast Routing Protocol In A Wireless Ad-Hoc Network To Improve Channel Utilization, Zhong Hua Zhou
An All-To-All Multicast Routing Protocol In A Wireless Ad-Hoc Network To Improve Channel Utilization, Zhong Hua Zhou
Theses and Dissertations
Wireless Ad-hoc network has become more and more popular. Several different multicasting schemes for this type of network have been developed. But most of them are targeting a situation where the total number of senders is much less than the total number of receivers. This thesis analyzes different wireless communication patterns in ad hoc network, the trend for wireless communication and presents a new multicast scheme. It targets an ad-hoc network where all mobile hosts act as both senders and receivers. The proposed scheme in this thesis will reduce overheads by combining data packets that are destined for the same …
The Relationship Of Small Mammal Species To Habitat Variables In West-Central Georgia And East-Central Alabama, Patricia Maureen Kosky
The Relationship Of Small Mammal Species To Habitat Variables In West-Central Georgia And East-Central Alabama, Patricia Maureen Kosky
Theses and Dissertations
The objective of this investigation was to assess the impact of environmental variables upon small mammal species distribution in 60 plots on Fort Benning, Muscogee and Chattahoochee Counties, Georgia and Russell County, Alabama. The small mammal fieldwork was carried out in December of 1994 through January of 1995. The vegetation was inventoried in June through October of 1995. During this period, 235 small mammals were trapped in a total of 5950 trap nights. A total of 10 small mammal species and 234 plant species were identified. The small mammal species abundance's were determined by using snap trapping along the plot …
The Effect Of Divalent Cations On The Prophenoloxidase Enzyme Cascade Activity In The Freshwater Crayfish Cambarus Latimanus, Hans Skailand Eikaas
The Effect Of Divalent Cations On The Prophenoloxidase Enzyme Cascade Activity In The Freshwater Crayfish Cambarus Latimanus, Hans Skailand Eikaas
Theses and Dissertations
The effect of divalent cations such as cadmium, calcium, copper, lead and magnesium upon the prophenoloxidase system (proPO) was studied in hemocytes of the crayfish Cambarus latimanus. It was demonstrated that cadmium, calcium, copper and lead increased proPO activity significantly, whereas magnesium had no statistically significant effect on the system. Also, the molecular weight of the proPO enzyme was estimated using SDS-PAGE and found to be approximately 76 kDa.
Analysis Of Hydric Pine Flatwood Ephemeral Pool Macroinvertebrate And Crustacean Assemblages Along A Temporal And Spatial Gradient From A Hypothesized Colonial Source, Henry Leon Griffith
Analysis Of Hydric Pine Flatwood Ephemeral Pool Macroinvertebrate And Crustacean Assemblages Along A Temporal And Spatial Gradient From A Hypothesized Colonial Source, Henry Leon Griffith
Theses and Dissertations
A survey of the macroinvertebrate and crustacean assemblages in hydric pine flatwood wetlands during fill and drawdown periods was conducted from September to November 1998, in Lee County, Florida. Physical and chemical information, relationships between community composition and physical and chemical conditions were analyzed and a monitoring plan for detecting impacts of declining water supply in hydric pine flatwood communities was proposed. In addition, possible sources of colonists and patterns of community assemblage were investigated. Twelve ephemeral pools and three associated intermittently exposed cypress heads were sampled monthly, over three months, using 1 D-ring benthic sweep, 2 Hester-Dendy multiple plate …
A Comparison Of Movements And Burrow Usage Between Indigenous And Relocated Gopher Tortoises (Gopherus Polyphemus) In A Fall Line Sandhills Community, Dorinda Morpeth
A Comparison Of Movements And Burrow Usage Between Indigenous And Relocated Gopher Tortoises (Gopherus Polyphemus) In A Fall Line Sandhills Community, Dorinda Morpeth
Theses and Dissertations
The movements and burrow use of twenty (ten relocated and ten indigenous to the relocation site) adult gopher tortoises {Gopherus polyphemus) were followed during the late spring, summer and early autumn in Talbot County, Georgia. The objectives of this study were to determine whether relocated gopher tortoises developed fidelity to a relocation site, and whether indigenous tortoises reacted adversely to relocated tortoises released in their proximity. Ten tortoises in the right-of-way of a highway construction project were captured, fitted with transmitters, and relocated to a 336 hectare tract of land, 3.2 km east of Geneva, Talbot, County, Georgia. Concurrently, ten …
A Descriptive Survey Of Freshwater Unionidae Bivalves In Five Creeks Located In West Central Georgia, Rufus Carson Stringfellow
A Descriptive Survey Of Freshwater Unionidae Bivalves In Five Creeks Located In West Central Georgia, Rufus Carson Stringfellow
Theses and Dissertations
A descriptive survey of the West Georgia, Chattahoochee River drainage unionid bivalve fauna inhabiting Mountain Oak, Mulberry, Standing Boy, and Upatoi Creeks has been completed. The survey is intended to determine whether Unionidae populations remain extant in this portion of the Chattahoochee River drainage, and to estimate the abundance and distribution of species encountered. Accessibility sampling was employed; sites selected to be surveyed were usually located at a road bridge or some landmark easily identifiable for geographical positioning. Collecting methods included the use of a small rake in sandy or silty substrate, visual detection of siphons or trails in the …
