Freshwater Macroinvertebrate Communities In Baldwin County, Georgia, Heath Michael Ghioto, Michelle K. Murdock, Nadya S. Gutierrez, Kristine N. White Ph.D.
Freshwater Macroinvertebrate Communities In Baldwin County, Georgia, Heath Michael Ghioto, Michelle K. Murdock, Nadya S. Gutierrez, Kristine N. White Ph.D.
Georgia Journal of Science
Freshwater ecosystems are critical habitats for maintaining biodiversity, often providing refuge for organisms especially in urban settings. Baldwin County, GA is home to many freshwater lakes that are part of the Oconee River watershed. Despite ongoing water quality monitoring, aquatic macroinvertebrates are under studied in the area. Aquatic macroinvertebrate diversity of one forested and one residential lake in Milledgeville, GA was documented for the first time. Despite low sample size, community composition was significantly different between lakes, with 27 families in Lake Laurel (forested), 44 families in Lake Oliver Hardy (residential), and only 19 families collected from both lakes. Seasonal …

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 …
Fire History Of A Georgia Montane Longleaf Pine (Pinus Palustris) Community, Nathan Klaus
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 …
Effects Of A Prescribed Burn On The Adult Butterfly Assemblage Of A Coastal Grassland, J. Nicole Desha, Joseph Colbert, Kimberly M. Andrews, Scott Coleman, C. Tate Holbrook
Effects Of A Prescribed Burn On The Adult Butterfly Assemblage Of A Coastal Grassland, J. Nicole Desha, Joseph Colbert, Kimberly M. Andrews, Scott Coleman, C. Tate Holbrook

Coastal grasslands are globally threatened by development and natural succession. In the southeastern United States, these increasingly rare ecosystems are being managed using prescribed fire, but ecological responses to fire management are largely unknown, particularly among nontargeted species. We tested for short-term effects of controlled burning on the abundance and species richness of adult butterflies, which utilize coastal grasslands for nectaring resources and as migratory stopover sites. In February 2015, four plots of coastal grassland on Little St. Simons Island, GA were burned and paired with unburned (control) plots of equal size. Throughout the following summer-fall flight season, we conducted …
Population Genetic Divergence Of Isle Royale Pearl Dace, Margarita Margariscus (Cyprinidae)., John F. Elder Jr., Jack R. Martin, Isaac J. Schlosser, Larry Kallemeyn
Population Genetic Divergence Of Isle Royale Pearl Dace, Margarita Margariscus (Cyprinidae)., John F. Elder Jr., Jack R. Martin, Isaac J. Schlosser, Larry Kallemeyn
Georgia Journal of Science
In 1949, Hubbs and Lagler described morphological variation among pearl dace (Margariscus margarita) of inland lakes on Isle Royale, Michigan. For Harvey Lake, Hubbs and Lagler, proposed that pearl dace were sufficiently morphologically distinct to warrant subspecific status. They argued that divergence of the Harvey Lake pearl dace was due to allopatric differentiation in isolation from lower elevation lakes. Harvey Lake has been isolated by elevation from lower elevation lakes for approximately 10 to 15 thousand years. No genetic studies have been done on Isle Royale pearl dace to evaluate this hypothesis to date. Here we report the analysis of …
