Successional Processes In The Benthic Invertebrate Communities At Gray’S Reef National Marine Sanctuary, Alexis A. Bivens
Successional Processes In The Benthic Invertebrate Communities At Gray’S Reef National Marine Sanctuary, Alexis A. Bivens
Honors College Theses
While the process of community development has been studied in terrestrial habitats since the turn of the 20th century, similar information is not as readily available in marine systems. Understanding patterns of community development is essential to predicting recovery potential and to designing effective marine protected areas. In the South Atlantic Bight, invertebrate communities on hard substrata can differ significantly from one rocky outcrop to another, but the factors driving these differences are not well understood. I documented the initial development of the benthic invertebrate community at Gray’s Reef National Marine Sanctuary (GRNMS) to address the prediction that this system …
Testing Viability Of Oligonucleotide Primers On Microsatellite Markers Amplified By Polymerase Chain Reaction On Dermacentor Variabilis Samples From The Bulloch County Region Of Georgia, Usa, Danielle Souza
Honors College Theses
Dermacentor variabilis, more commonly known as the wood tick, or the American dog tick, can be found all over North America. D. variabilis is a common tick in Bulloch county, Georgia, USA, and little is known about the population structure of this population of the species. Microsatellite markers are able to locate sections of the genome and can aid in estimating relatedness among individuals in a population. Six different oligonucleotide primer pairs were published for D. variabilis, however, published and non-published works indicated that not all of those primer pairs were working equally well for PCR. This study is …
Predictors Of Fish Assemblage Structure And Dynamics In Atlantic Coastal Plain Streams, Rebecca Scott
Predictors Of Fish Assemblage Structure And Dynamics In Atlantic Coastal Plain Streams, Rebecca Scott
Electronic Theses and Dissertations
Effective management of freshwater fishes requires a mechanistic understanding of the drivers of assemblage composition; in other words, what determines who is where and when. Stream fish assemblages are potentially influenced by environmental factors that act on multiple spatiotemporal scales, but the relative influence of these drivers may vary between geophysically distinct regions. This study sought to determine the patterns and drivers of fish taxonomic and functional assemblage composition in the coastal plain, a region possessing unique hydrologies, faunas, and physiochemical conditions. I addressed this goal using two complementary chapters, both of which utilized environmental and biotic data collected from …
Comparison Of Three Benthic Macroinvertebrate Passive Sampling Devices For Non-Wadeable Streams, Kelsey A. Laymon
Comparison Of Three Benthic Macroinvertebrate Passive Sampling Devices For Non-Wadeable Streams, Kelsey A. Laymon
Electronic Theses and Dissertations
Rivers and streams provide essential ecosystem services to the degree that the monitoring and maintenance of these systems becomes imperative. Biomonitoring provides managers and policymakers with the tools to make informed decisions, and macroinvertebrates are often the object of biomonitoring because they are ubiquitous in most systems and are known to be good indicators of water quality. However, methods for sampling macroinvertebrates in non-wadeable streams (i.e., large rivers) have not been standardized across states and regions and an established method for macroinvertebrate biomonitoring in large rivers of Georgia is not currently available. My study compared macroinvertebrates collected with three types …
