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 …

Macroinvertebrates are sensitive to environmental conditions, giving them the ability to be utilized in studies indicating the health of their environment. Additionally, macroinvertebrates are an important food source for vertebrates and invertebrates. Since macroinvertebrates play such significant roles in the ecosystem, it is important to identify and document their presence. In order to begin documenting the macroinvertebrates in central Georgia, aquatic macroinvertebrates were collected from ten sampling sites along a transect of central Georgia. Live specimens were imaged, preserved, identified, and sequenced. COI mitochondrial DNA and 18s nuclear DNA and 3D images of the organisms were made publicly available. The …

Escherichia coli and enterococci were enumerated in water collected biweekly for one year at ten stations in the Alapahoochee River system. The concentrations of E.coli were usually below a standard of 576 colony forming units (cfu) per 100 ml, except after heavy rain. At five stations the concentrations of enterococci were generally above a standard of 151 cfu/100 ml. Concentrations of both groups showed a direct but weak correlation with pH. For quality control, 772 colonies typical of E. coli and 773 colonies typical of enterococcus were tested by the appropriate verification procedures. Sixty-six (8.5%) of the former, and 57 …
