Fish Assemblages Of The Withlacoochee River Basin In South Georgia, Usa, Matthew J. Cannister, David L. Bechler Dec 2019

Fish Assemblages Of The Withlacoochee River Basin In South Georgia, Usa, Matthew J. Cannister, David L. Bechler

Georgia Journal of Science

An ichthyofauna review of literature prior to 2008 on the Withlacoochee River basin in south-central Georgia, USA, indicated that the fish fauna was underrepresented compared to other rivers, such as the Suwannee River basin in Florida of which the Withlacoochee River is a tributary. A survey would provide the state of Georgia potentially valuable additional information on the fish fauna within the basin. A 45-site survey within the eastern portion of the Withlacoochee River basin was conducted from 2008 to 2010 employing seines, gill nets, fish traps, trotlines, and creel surveys. Surveys yielded 51 fish species of which three, the …


Results Of A Fall And Spring Bioblitz At Grassy Pond Recreational Area, Lowndes County, Georgia., Emily Cantonwine, James Nienow, Mark Blackmore, Brandi Griffin, Brad Bergstrom, David Bechler, Timothy Henkel, Christopher A. Slaton, James Adams, Arthur Grupe, Malcolm Hodges, Gregory Lee Nov 2019

Results Of A Fall And Spring Bioblitz At Grassy Pond Recreational Area, Lowndes County, Georgia., Emily Cantonwine, James Nienow, Mark Blackmore, Brandi Griffin, Brad Bergstrom, David Bechler, Timothy Henkel, Christopher A. Slaton, James Adams, Arthur Grupe, Malcolm Hodges, Gregory Lee

Georgia Journal of Science

Two 24 h BioBlitzes were conducted in September, 2018, and April, 2019, at Grassy Pond Recreational Area in Lowndes County, Georgia. Teams of scientists, students, and public participants surveyed plants, insects, amphibians and reptiles, birds, mammals, fungi, lichens, and aquatic microorganisms. Both events included educational programs with informational walks and activities targeted to youth. In the fall, 654 species and 55 additional genera were recorded. In the spring, there were 581 species and 54 additional genera recorded. Two fungi and 38 lichens were first reports for Lowndes County; one fungus was a first for Georgia. One lichen may be a …


Dental And Mandibular Anomalies In White-Tailed Deer (Odocoileus Virginianus) From Central Georgia, Patrick M. Powers, Alfred J. Mead Oct 2019

Dental And Mandibular Anomalies In White-Tailed Deer (Odocoileus Virginianus) From Central Georgia, Patrick M. Powers, Alfred J. Mead

Georgia Journal of Science

The frequency of dental and mandibular anomalies in free-ranging white-tailed deer in the southeastern United States is not well documented. Characteristic irregularities include supernumerary and missing teeth, malocclusion, root abscesses due to bacterial infections, and tooth or bone damage due to trauma. In the present study, we examined 778 white-tailed deer dentaries collected from the Piedmont National Wildlife Refuge in central Georgia. All dentaries were inspected for lesions, tooth irregularities, developmental anomalies, and other pathologies. Thirty-two dentaries (4.1%) displayed signs of dental or bone abnormalities. More abnormalities were associated with infection or injury (22/778, 2.8%) compared to unusual tooth development …


Short Term Effects Of Hurricane Irma On The Phytoplankton Of Lake Louise, Georgia, Usa, Marque'l K. Gould, Adam J. Nienow, Anastasia V. F. Nienow, James A. Nienow Sep 2019

Short Term Effects Of Hurricane Irma On The Phytoplankton Of Lake Louise, Georgia, Usa, Marque'l K. Gould, Adam J. Nienow, Anastasia V. F. Nienow, James A. Nienow

Georgia Journal of Science

Natural disturbances such as fires and severe storms can have profound impacts on the hydrology and ecology of inland waters, potentially altering the structure and function of the ecosystem for extended periods of time. Studies of the initial impacts are, however, uncommon. Here we report on the short-term impacts of Hurricane Irma in the structure of the phytoplankton association in Lake Louise, a small blackwater lake in southern Georgia. Irma hit the region on September 11, 2017, with tropical storm force winds. The event corresponded to a period during which we were conducting routine weekly monitoring of environmental conditions in …


Turtles Of The Early Pleistocene Santa Fe River 1b Locality, Dennis Parmley, Robert Chandler, Linda Chandler Aug 2019

Turtles Of The Early Pleistocene Santa Fe River 1b Locality, Dennis Parmley, Robert Chandler, Linda Chandler

Georgia Journal of Science

The early Pleistocene (ca. 2.588–1.806 Ma) Santa Fe River 1B fossil site (SF1B) of Gilchrist County, Florida has yielded turtle fossils representing nine genera and at least 10 species. Of these, at least six genera are aquatic turtles (Macrochelys and/or Chelydra, Apalone, Trachemys, Pseudemys, Sternotherus, and Kinosternon) and three are terrestrial (Hesperotestudo, Gopherus, and Terrapene). Hesperotestudo and an undescribed cf. Trachemys are the only extinct turtles identified in the paleoherpetofauna. Overall, the generic composition of the turtle fauna is predominantly modern and indicative of the southeastern United States today.

A Tentative List Of The Land Snails Of Georgia, U.S.A., Zachary I. Felix, Michael A. Dubuc, Hassan A. Rana Jul 2019

A Tentative List Of The Land Snails Of Georgia, U.S.A., Zachary I. Felix, Michael A. Dubuc, Hassan A. Rana

Georgia Journal of Science

Because of their high ecological and conservation value, and because we know so little about the group, we compiled a systematic if tentative list of land snails from the state of Georgia. After gleaning a list of species from a monograph on the land snails of eastern United States, written by Leslie Hubricht in 1985, we realized that many species whose ecological requirements are found in Georgia had not been documented there. Therefore, we developed a qualitative model to predict the likelihood that these candidate species occur in Georgia and would eventually be documented. We tested the model with collections …


Eocene Terrestrial Mammals From Central Georgia, Parker D. Rhinehart, Alfred J. Mead, Dennis Parmley Jun 2019

Eocene Terrestrial Mammals From Central Georgia, Parker D. Rhinehart, Alfred J. Mead, Dennis Parmley

Georgia Journal of Science

Descriptions of fossils of Eocene terrestrial mammals from the southeastern United States are rare, and particularly so in the Eocene sediments of Georgia. Here we describe a small collection of fossilized teeth and tooth fragments representing four mammalian taxa. The fossils were recovered by surface collecting overburden sediments and screen washing in situ Clinchfield Formation sediments exposed in an inactive kaolin mine, Hardie Mine, in Wilkinson County, Georgia. The Clinchfield Formation has been described as a Late Eocene coastal unit with abundant gastropods, bivalves, sharks, and rays. This is the first detailed description of terrestrial mammals from this unit. Although …


Fire History Of A Georgia Montane Longleaf Pine (Pinus Palustris) Community, Nathan Klaus May 2019

Fire History Of A Georgia Montane Longleaf Pine (Pinus Palustris) Community, Nathan Klaus

Georgia Journal of Science

Montane longleaf pine forests, woodlands, and savannas are endangered, fire-dependent ecosystems of the Piedmont, Ridge and Valley, Appalachian, and Cumberland Plateau physiographic provinces of Georgia, Alabama, and North Carolina. Compared to other longleaf pine ecosystems, e.g., longleaf pine-wiregrass, little has been published about montane longleaf pine ecosystems. Understanding the historic fire regimes that once maintained montane longleaf pine ecosystems is an important first step toward achieving restoration and conservation goals for this ecosystem. I used two approaches to investigate historic fire regimes: 1) a dendrochronological study of fire scars on Sprewell Bluff Natural Area and 2) calculations of the average …


Identifying Roadkill Hotspots Using A Running Average, Kori A. Ogletree, Alfred J. Mead, Evan R. Boitet Apr 2019

Identifying Roadkill Hotspots Using A Running Average, Kori A. Ogletree, Alfred J. Mead, Evan R. Boitet

Georgia Journal of Science

The identification of roadkill hotspots is necessary prior to the consideration of wildlife road mortality mitigation measures. In a previous study, 178 roadkill specimens were tallied via a driving survey along 21.4 km (13.3 mi) on three connected roadways in Baldwin County, Georgia. Roadkill locations were recorded to the nearest 0.16 km (0.1 mi) using the vehicle odometer. In the current study, location data were used to generate three graphical displays of roadkill distribution: 1) a linear graph of roadkills per 0.16 km (0.1 mi) bin; 2) a linear graph of roadkills per 0.8 km (0.5 mi) bin; and 3) …
