A Temporal Analysis Of The Microbiota And Biofouling Development On Artificial Substrates In The Port Everglades Inlet, Florida, Denise Swack
All HCAS Student Capstones, Theses, and Dissertations
A pilot project was deployed in Port Everglades Inlet, Florida that aimed to evaluate the biofilm composing the microbiome on ecologically engineered artificial substrates used to build Coastal Marine Infrastructure. In April of 2017, an Articulated Concrete Block Mattress comprised of an ecological engineered concrete substrate and a standard smooth surface control substrates were compared. This study will provide a profile on the microbiome community on artificial substrates within Port Everglades Inlet on bio-enhancing concrete-based solutions in our Coastal Marine Infrastructure. To study the microbial community, the 16s rRNA technology was used in Illumina’s high-throughput DNA sequencing. Samples were collected …
Investigation Of Sulfur Cycling In Marine Sponge Cinachyrella Spp. From A South Florida Reef, Shelby K. Cain
Investigation Of Sulfur Cycling In Marine Sponge Cinachyrella Spp. From A South Florida Reef, Shelby K. Cain
All HCAS Student Capstones, Theses, and Dissertations
Symbionts within marine sponges are actively participating in the biogeochemical cycles. Among them, the role of symbiont microbes in the sulfur cycle remains a mystery. This study measured the abundance of microbes within the genus Cinachyrella before and after exposure to hydrogen sulfide. A four-part study was conducted: a) five-hour drop experiments, b) vertical distribution experiments, c) five-hour uptake experiments, and d) long-term exposure experiments. The five-hour drop experiment utilized a microsensor to measure sulfide levels, which was lowered 1.0 mm every thirty minutes for a total of 5 hours. Three trials were performed, each with one sponge and a …
Characterization Of Bacterial Communities In Biscayne Bay Through Genomic Analysis, Eric Fortman
Characterization Of Bacterial Communities In Biscayne Bay Through Genomic Analysis, Eric Fortman
HCNSO Student Theses and Dissertations
Biscayne Bay is a shallow oligotrophic estuary in Southeast Florida. Channelization of rivers, and dredging of canals has greatly altered the historical flow of fresh water into the bay. This, coupled with the rise of a sprawling urban & suburban development, has greatly increased the nutrient load in the bay. This study examined the bacterial community at 14 stations throughout Biscayne Bay —6 stations were located at the mouths of canals; 1 upstream-canal station; 6 stations in the center of the bay; and one ocean influenced station, located near the entrance to the bay. One liter, surface water samples were …
Microbiome And Bacterioplankton Rrna Gene Sequence Data Collected From Gulf Of Mexico Seawater Samples, Cruises Dp03 And Dp04 From April - August 2016, Cole Easson, Lindsey Freed
Microbiome And Bacterioplankton Rrna Gene Sequence Data Collected From Gulf Of Mexico Seawater Samples, Cruises Dp03 And Dp04 From April - August 2016, Cole Easson, Lindsey Freed
DEEPEND Datasets
Seawater was collected and filtered for microbiome and bacterioplankton sequencing and analyses at various depths during planned DEEPEND cruise expeditions to the GOM in 2016. Filters were stored and then processed for total environmental genomic DNA according to standard methods (see earthmicrobiome.org). 16S rRNA amplicon libraries covering the V4 hypervariable regions were generated with universal PCR primers and then sequenced on an Illumina MiSeq DNA sequencing platform. Raw paired-end sequences were joined and quality filtered in the bioinformatics program, QIIME. Vertical baseline characterizations will track alpha and beta diversity at different depths ranging from 0 – 1500 m, assess seasonal …
Characterization Of The Marine Sponge Amphimedon Compressa Microbiome Across A Spatial Gradient, Renee Michelle Potens
Characterization Of The Marine Sponge Amphimedon Compressa Microbiome Across A Spatial Gradient, Renee Michelle Potens
HCNSO Student Theses and Dissertations
Diverse and ecologically important microbial communities (microbiomes) are symbiotic within marine sponges. In this study, the microbiome of Amphimedon compressa from three sample locations (Broward and Dade Counties, Southeast Florida, USA and the Southern Caribbean, Bocas del Toro, Panama) is characterized using 16S rRNA Illumina sequencing. The predominant taxa are Proteobacteria and Cyanobacteria, as expected for Low Microbial Abundance sponges, accounting for over 53% of the total microbiome community. The numbers of Operational Taxonomic Units (OTUs) decrease from Broward County (2,900) to Dade County (2,300) and then Bocas del Toro (1,200). The correlates to a decreasing north-south gradient of …
