The Effects Of Hydrologic Heterogeneity On Harmful Algal Blooms In Freshwater Reservoir, Lake Sinclair, Georgia, Margaret Blackledge
The Effects Of Hydrologic Heterogeneity On Harmful Algal Blooms In Freshwater Reservoir, Lake Sinclair, Georgia, Margaret Blackledge
Biology Theses
Aquatic habitats are frequently studied after a major water quality problem like the occurrence of an algal bloom. In this study, A proactive rather than a reactive response was considered, where the complexity of conditions conducive to uncontrolled cell growth were studied before a bloom took place by sampling regularly. This study aimed to monitor water quality by monthly sampling of algal communities for approximately one year. As the base of the aquatic food web, algae are a highly diverse group of organisms with varying sensitivity to physical and chemical changes in the environment. Four shallow sites were monitored at …
Soil Macroinvertebrates Responses To Wildfires In The Blue Ridge Mountains, Usa, Madeline Olliff
Soil Macroinvertebrates Responses To Wildfires In The Blue Ridge Mountains, Usa, Madeline Olliff
Biology Theses
Fire has been a prevalent disturbance on Earth for millions of years. Around the globe there are several regions that have become fire adapted, including the Southeastern United States. There have been few studies examining the effects of wildland fires on soil macroinvertebrates in the Blue Ridge Mountains, in spite of the importance of these animals to soil processes and their contributions to the biodiversity of these ecosystems. During the fall of 2016, the Southeastern USA experienced numerous, large wildfires. These fires offered an opportunity to study the effects of wildland fire on soil macroinvertebrates. We sampled sites from three …
Molecular Detection Of Pathogenic Leptospira And Microbial Source Tracking Of Fecal Pollution In San Juan, Puerto Rico, Taylor I. Chapman
Molecular Detection Of Pathogenic Leptospira And Microbial Source Tracking Of Fecal Pollution In San Juan, Puerto Rico, Taylor I. Chapman
Biology Theses
Leptospirosis, caused by pathogenic Leptospira, is endemic to tropical regions. Leptospira is released into the environment through the secretion of urine from animals, making it easily transmissible through water sources. The estuarian environment surrounding the area of San Juan, Puerto Rico and its high density of urban development creates ideal conditions for transmission of Leptospirosis. The goal of this study was to determine the presence of Leptospira in these surface waters and use Microbial Source Tracking (MST) to identify the possible source of pathogenic Leptospira. Eighty-seven water samples were collected during the dry (44) and wet (43) seasons. …
Terrestrial Soldier Crab (Coenobita Clypeatus, Fabricius 1787) And Cerion Spp. (Röding 1798) Shell Relationship On San Salvador Island, Bahamas, Harley Hunt
Biology Theses
The Caribbean terrestrial soldier crab, Coenobita clypeatus(Fabricius 1787), coexist and utilize the shells of numerous species of land and marine gastropods. Soldier crabs rely on gastropod shells for protection as the crabs have a soft abdomen, leaving them vulnerable for predation and desiccation, threatening their survival. This creates a strong pressure to obtain well-fitting shells that provide adequate protection against water loss. Cerion of Röding (1798) shells are one of the most commonly used shells among living colonies of C. clypeatuson San Salvador Island. This study is interested in the frequency of shell use by C. clypeatus crabs …
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 …
