Preliminary Analysis Of The Effects Of Non-Target Supplemental Feeding On Camera Trap Captures Of Small Mammals In Central Georgia, Raena Mccown, Travis Cunningham, Alfred J. Mead
Preliminary Analysis Of The Effects Of Non-Target Supplemental Feeding On Camera Trap Captures Of Small Mammals In Central Georgia, Raena Mccown, Travis Cunningham, Alfred J. Mead
Georgia Journal of Science
Supplemental bird feeding is a widespread hobby throughout western culture. Although it brings joy to many people, bird feeding has been shown to have potentially negative effects on local bird populations and small mammalian species. To study the differences in local occurrence of native small mammalian species around bird feeders and in more distant settings, six camera traps were placed in a rural residential area in Putnam County, Georgia. Three cameras were placed facing bird feeders and three placed a minimum of 60 m away from the feeders. Species presence was recorded three days a week from 12:00 am Monday …
Late Pleistocene Rodents From Clark Quarry, A Vertebrate Fossil Locality In Southeastern Georgia, Parker Rhinehart
Late Pleistocene Rodents From Clark Quarry, A Vertebrate Fossil Locality In Southeastern Georgia, Parker Rhinehart
Biology Theses
Clark Quarry is a Late Pleistocene fossil locality near Brunswick, GA, United States with a diverse vertebrate fauna. Morphological descriptions of Mammuthus columbi (Columbian Mammoth), snakes, amphibians, and birds from Clark Quarry have previously been completed along with a stable isotope analysis of M. columbi and Bison latifrons (Long-horned Bison) enamel. Herein, the rodent fauna is described using primarily teeth recovered by screen-washing quarry sediment. Nine rodent taxa have been identified, two of which are the extinct species Synaptomys australis (Florida Bog Lemming) and Neochoerus aesopi (Late Pleistocene Capybara). Of the remaining seven taxa, Erethizon dorsatum (North American Porcupine) and …
Pleistocene Rodents From Southeast Georgia, Parker Rhinehart
Pleistocene Rodents From Southeast Georgia, Parker Rhinehart
Graduate Research Showcase
Late-Pleistocene fossil sites are uncommon in Georgia. However, Clark Quarry, a locality near Brunswick, Georgia, has yielded a large and diverse collection of vertebrate skeletal material dominated by cranial and post-cranial fossils of Columbian mammoths (Mammathus columbi) and giant bison (Bison latifrons). Screen washing of the fossiliferous sediment associated with the bones of the megafauna has produced a large number of microfossils. Here I describe fossil rodents from Clark Quarry. Cranial and post-cranial material of eight rodent taxa have been identified to date. Of these, five are found in the area today: Sigmodon hispidus, Peromyscus sp., …
Several Vegetation Characteristics Affect Reproductive Success Of Grassland Birds At A Restored, Warm-Season Grassland In Central Georgia, Kayla B. Allen
Several Vegetation Characteristics Affect Reproductive Success Of Grassland Birds At A Restored, Warm-Season Grassland In Central Georgia, Kayla B. Allen
Biology Theses
Grassland birds are experiencing major population declines due to habitat loss and fire suppression throughout North America. Large-scale grassland restoration efforts are ongoing, but there is little data on breeding bird productivity on restored habitats, nor on the impact of specific vegetation characteristics on reproductive output. Since 2005, agriculture fields at Panola Mountain State Park, GA have been undergoing restoration to warm-season grasslands; however, up until now there has been no monitoring of nest success or productivity. The goals of this project are to 1) quantify reproductive success and 2) determine which vegetation characteristics are associated with reproductive success. From …
Assessment Of Culverts And Bridges As Roosting Habitat For Perimyotis Subflavus (Tri-Colored Bat) And Disease Transmission Corridors For Pseudogymnoascus Destructans, Kelly Lutsch
Master of Science in Integrative Biology Theses
Pseudogymnoascus destructans is an emerging fungal pathogen causing precipitous declines in North American bats due to the development of white-nose syndrome. Since 2006, 34 U.S. states and 7 Canadian provinces have confirmed the presence of P. destructans. Due to the rapid spread of P. destructans across the eastern United States, habitat characterization and disease monitoring has become vital to conserving remnant populations. Bats have been observed in multiple states using non-traditional habitat, such as interstate culverts, for roosting. To investigate their use of anthropogenic structures in coastal Georgia, an area where P. destructans has yet-to-be detected, comprehensive bridge and …
Landscape Features Affecting Northern Bobwhite Predator-Specific Nest Failures In Southeastern Usa, Susan N. Ellis-Felege, Shannon E. Albeke, Nathan P. Nibbelink, Michael J. Conroy, Clay Sisson, William E. Palmer, John P. Carroll
Landscape Features Affecting Northern Bobwhite Predator-Specific Nest Failures In Southeastern Usa, Susan N. Ellis-Felege, Shannon E. Albeke, Nathan P. Nibbelink, Michael J. Conroy, Clay Sisson, William E. Palmer, John P. Carroll
Biology Faculty Publications
Nest predation is a critical component in avian productivity and typically is the leading cause of nest failure for most birds. Several landscape features are thought to drive the behavioral interaction between northern bobwhite (Colinus virginianus; e.g., nest placement) and their predators (e.g., search methods for food acquisition). In order to understand habitat characteristics influencing predation, we studied bobwhite nests using 24-hour near-infrared video cameras. We monitored 675 bobwhite nests with cameras on 3 properties in northern Florida and southern Georgia, USA, during 2000–2006. To test the association between nest failures and specific failure causes with landscape structure, we calculated …
Fluctuating Asymmetry In Two Common Freshwater Fishes As A Biological Indicator Of Urbanization And Environmental Stress Within The Middle Chattahoochee Watershed, William I. Lutterschmidt, Samantha L. Martin, Jacob F. Schaefer
Fluctuating Asymmetry In Two Common Freshwater Fishes As A Biological Indicator Of Urbanization And Environmental Stress Within The Middle Chattahoochee Watershed, William I. Lutterschmidt, Samantha L. Martin, Jacob F. Schaefer
Faculty Publications
Deviations in bilateral symmetry or fluctuating asymmetry of an organism may result under environmental stressors that reduce developmental homeostasis and stability. Anthropogenic stressors such as increased urbanization can negatively impact environmental quality of aquatic ecosystems. Researchers have stressed the value in finding easy, accurate and inexpensive methods for assessing potential stress within ecosystems. Here we use fluctuating asymmetry (FA) as a useful quantitative tool in assessing the environmental quality and potential urban-based stressors within eight creeks of the Bull and Upatoi Creeks Watershed within the larger watershed of the Middle Chattahoochee. Using Geographic Information System (GIS), we characterize land-use patterns …
Host-Plant Preference Of Megacopta Cribraria, Taylor Upole
Host-Plant Preference Of Megacopta Cribraria, Taylor Upole
The Corinthian
The purpose of this study was to examine the host plant preferences of M. cribraria. We first hypothesized that M. cribraria prefers its native host plant when given the choice between kudzu and soybeans. If M. cribraria prefers kudzu over soybeans, it may indicate that M. cribraria could be an effective biological control agent for kudzu. We also wanted to determine if M. cribraria prefers soybean plants inoculated with nitrogen fixing rhizobia over non-inoculated soybean plants. Our hypothesis is that M. cribraria will prefer the inoculated soybeans to the non-inoculated soybeans due to the increased nitrogen.
The Phenology Of Ticks And The Effects Of Long-Term Prescribed Burning On Tick Population Dynamics In Southwestern Georgia And Northwestern Florida, Elizabeth R. Gleim, L. Mike Conner, Roy D. Berghaus, Michael L. Levin, Galina E. Zemtsova, Michael J. Yabsley
The Phenology Of Ticks And The Effects Of Long-Term Prescribed Burning On Tick Population Dynamics In Southwestern Georgia And Northwestern Florida, Elizabeth R. Gleim, L. Mike Conner, Roy D. Berghaus, Michael L. Levin, Galina E. Zemtsova, Michael J. Yabsley
Environmental Studies / Environmental Science Faculty Scholarship
Some tick populations have increased dramatically in the past several decades leading to an increase in the incidence and emergence of tick-borne diseases. Management strategies that can effectively reduce tick populations while better understanding regional tick phenology is needed. One promising management strategy is prescribed burning. However, the efficacy of prescribed burning as a mechanism for tick control is unclear because past studies have provided conflicting data, likely due to a failure of some studies to simulate operational management scenarios and/or account for other predictors of tick abundance. Therefore, our study was conducted to increase knowledge of tick population dynamics …
A Morphological And Genetic Analysis Of Forensically Important Blow Flies, From Georgia: The Genus Lucilia, Katie S. Googe
A Morphological And Genetic Analysis Of Forensically Important Blow Flies, From Georgia: The Genus Lucilia, Katie S. Googe
Honors College Theses
Identification of Blow flies (Diptera: Calliphoridae) to species is important for estimating postmortem intervals, because insect species develop at different rates. Three Blow fly species in Georgia; Lucilia coeruleiviridis, L. cuprina, and L. sericata are similar morphologically, making identification difficult. Furthermore, the status of L. cuprina is in doubt; this species may be a complex of true L. cuprina, and L. cuprina x L. sericata hybrids. The objective of this study was to survey the Georgia Blow fly community and validate the statuses of L. coeruleiviridis, L. cuprina, and L. sericata, through morphological and …

The Effects Of Herbicide On The Endangered Herb Baptisia Arachnifera And Preliminary Nutrient Survey Of Leaf Tissue And Soil, Ruth Ann C. Steinbrecher
Electronic Theses and Dissertations
Baptisia arachnifera (Hairy Rattleweed) is an endangered herbaceous legume that only occurs in Wayne and Brantley Counties of Georgia, United States. Many of the remaining populations exist in areas now managed for timber. This study investigated the effects of Imazapyr, an herbicide commonly used in timber management, on health and vitality of B. arachnifera under both field and greenhouse conditions. This study also analyzed leaf and soil samples from six populations of B. arachnifera to determine the nutrient content of the leaves. A recensus of a B. arachnifera population was also conducted in a site without commercial timber management. In …

Today more than 23 million U.S. children and adolescents are either obese or overweight. Hospital costs from obesity-related diseases in youth have increased from $35 million (0.43% of total hospital costs) during 1979 to 1981 to $127 million (1.79% of total costs) during 1997 to 1999. During the Pathway to Med School program, I collaborated with three other students to develop a research project on childhood and adolescent obesity. We conducted surveys at nine different primary care clinics in the southwest Georgia area. Approval was sought by the Institutional Review Board of Phoebe Putney Memorial Health System and Albany Area …
Behavioural Display Systems Across Nine Anolis Lizard Species: Sexual Dimorphisms In Structure And Function, Michele A. Johnson, J. Wade
Behavioural Display Systems Across Nine Anolis Lizard Species: Sexual Dimorphisms In Structure And Function, Michele A. Johnson, J. Wade
Biology Faculty Research
Relationships between structure and function are a primary focus in biology, yet they are most often considered within individual species. Sexually dimorphic communication behaviours and the morphology of associated structures can vary widely, even among closely related species, and these traits provide an ideal opportunity to investigate the evolution of structure-function patterns. Using nine Anolis lizard species, we addressed a series of questions regarding sex differences in and the evolution of relationships between extension of the throat fan (dewlap) and morphology of the muscles and cartilage controlling it. The main results indicated that within species, males displayed the dewlap more …

The Winter Ecology Of The Piping Plover (Charadrius Melodus) In Coastal Georgia, Brandon Lennon Noel
Electronic Theses and Dissertations
Author's abstract: The Piping Plover (Charadrius melodus) is a federally listed species with three distinct breeding populations, including Great Plains (threatened), Great Lakes (endangered), and Atlantic Coast (threatened), all of which winter along the Atlnatic and Gulf coasts of the United States. I studied the winter ecology of the Piping Plovers on Little St. Simons Island (LSSI), Georgia, from 2003-2006, with emphasis on the conservation significance of this site for the endangered Great Lakes population. During 2003-2004 and 2004-2005, LSSI supported up to 100 Piping Plovers during peak migration, and approximately 40 birds wintered at this site. All populations had …

Nest Characteristics Of The Clapper Rail In Coastal Georgia, Karen F. Gaines, James C. Cumbee Jr., Warren L. Stephens Jr.
Karen F. Gaines
The nesting habitat of the Clapper Rail (Rallus longirostris) is not well studied in the southeastern United States. We documented Clapper Rail nest characteristics and surrounding habitats near Brunswick on the Georgia coast. Of 159 nests found, only 29 were active. Although some nests may have been abandoned or never used, many could have been depredated. Nests were constructed farther away from tidal influences than in those populations studied in the mid-Atlantic region of the United States. Clapper Rails also tended to nest near tidal pools as frequently as tidal creeks, contrasting with other Atlantic coast studies. The greater tidal …

The Prevalence Of Human Granulocytic Ehrlichiae In Ixodes Scapularis Ticks In Southeastern Georgia, Heather Anne Merten
The Prevalence Of Human Granulocytic Ehrlichiae In Ixodes Scapularis Ticks In Southeastern Georgia, Heather Anne Merten
Legacy ETDs
Human granulocytic ehrlichiosis (HGE) is a newly emerging, tick-borne zoonosis in North America. The agent that causes HGE is very similar to Ehrlichia phagocytophilia and Ehrlichia equi, but has yet to be classified as a separate species.
This study was carried out in order to determine the prevalence rate of HGE infection in blacklegged ticks (Ixodes scapularis) in insular and mainland sites in southeastern Georgia using nested PCR techniques. Four locations were studied representing 2 barrier islands and 2 mainland sites. We hypothesized that areas that have low levels of human disturbance and are somewhat isolated will …
The Effects Of Drought On Foraging Habitat Selection Of Breeding Wood Storks In Coastal Georgia, Karen F. Gaines, A. Lawrence Bryan Jr., Philip M. Dixon
The Effects Of Drought On Foraging Habitat Selection Of Breeding Wood Storks In Coastal Georgia, Karen F. Gaines, A. Lawrence Bryan Jr., Philip M. Dixon
Karen F. Gaines
Foraging habitat use by Wood Storks (Mycteria americana) during the breeding season was studied for three coastal colonies during a drought year and compared to habitat use during normal rainfall years. Information on the distribution of wetland habitat types was derived using U.S. Fish and Wildlife Service National Wetland In- ventory (NWI) data within a Geographic Information System (GIS). Foraging locations were obtained by following storks from their colonies in a fixed-winged aircraft. Differences in hydrologic condition and, the resulting prey availability in coastal zone freshwater wetlands greatly affected foraging habitat use and breeding success of the three stork colonies. …

Nest predation is an important source of mortality in songbirds and may contribute to declines in Neotropical migrants. I used artificial nests baited with fresh Japanese Quail and Zebra Finch eggs in conjunction with observations of natural nests to quantity the ettects ol nest height and vegetation on nest predation on St. Catherine's Island, a barrier island in southeast Georgia. Because of intense browsing by white-tailed deer. I predicted that lower, more exposed nests would be least successful. Artificial nests (n = 389) were placed in the field, and natural nests (n = 49) were observed, durintz April and May …
Temporal And Spatial Variation In Abundance Of Migratory Birds At Kennesaw Mountain, Georgia, Andrew Allen Kinsey
Temporal And Spatial Variation In Abundance Of Migratory Birds At Kennesaw Mountain, Georgia, Andrew Allen Kinsey
Legacy ETDs
Migratory birds spend a significant part of each year in transition between their breeding and resting grounds. During this transitional period migrants rely on stopover sites to provide them with the necessary habitat to replenish lost energy stores, rest, and wait for favorable weather conditions before continuing migration. The majority of stopover work related to passerines in North America has occurred along coastal migration routes. Meanwhile, relatively little work has been conducted at inland stopover sites, areas which may be equally important to migrating birds. Kennesaw Mountain is an isolated geographically prominent peak located in the foothills of the southern …

Detection Of Ehrlichia Chaffeensis In Ticks Of The Georgia Coast And Barrier Islands Using Polymerase Chain Reaction, John Edward Whitlock
Legacy ETDs
Human monocytic ehrlichiosis (HME) is an emerging, zoonosis transmitted to mammals by ixodid ticks. Prevalence of infected ticks and distribution of infection foci indicate relative risk of human exposure to ehrlichiosis and may be influenced by factors such as geographic isolation and human disturbance. To test this, individual and pooled lone star ticks, Amblyomma americanum (L.), collected from 3 populations from the coast and barrier islands of Georgia were screened for Ehrlichia chaffeensis Anderson, Dawson, Jone, and Wilson, the agent of HME. A species-specific, nested polymerase chain reaction (PGR) assay was used to amplify a 572 base pair fragment of …

Phenology And Bionomics Of Culicoides (Diptera: Ceratopogonidae) In Glynn County, Georgia, Lisa M. Westberry
Legacy ETDs
Seasonal abundance and population densities of Culicoides species from sites in Glynn County, Georgia were surveyed using 15 New Jersey light traps during a 9-month period from April-December 1990. Environmental effects on the abundances were also analyzed. The three primary species present were: Culicoides furens (Poey), C. hollensis Mellander & Brues, and C. melleus (Coguillett). C. furens were collected year round, but predominantly during the summer. C. hollensis had a bimodal abundance (spring and fall) . C. melleus also had a bimodal abundance (late summer and fall).
Larval habitats of the primary species were identified …
