Genomic Analysis Of Acropora Cervicornis Mucus And Sediments In The Florida Keys Tavernier Nursery, Rachel Zimmerman Aug 2018

Genomic Analysis Of Acropora Cervicornis Mucus And Sediments In The Florida Keys Tavernier Nursery, Rachel Zimmerman

HCNSO Student Theses and Dissertations

White Band disease has devastated the staghorn coral Acropora cervicornis in recent decades, and it continues to impinge upon restoration efforts. The etiological agent(s) remain unknown as Koch’s postulates have yet to be satisfied, but disease may originate when opportunistic pathogens in the surface mucus layer exploit a stressed host. Using 16s rRNA sequencing, differences in the taxonomic diversity and relative abundances of bacteria within the mucus of A. cervicornis were documented between colonies of the same genotype, genotypes (n=8) categorized as having either high or low WBD susceptibility, and during a transplantation event. A. cervicornis colonies suspended from midwater …


A Comparison Of Benthic Habitats And Faunas Between The Miami Terrace (Proposed Calypso Pipeline Site) And The Pourtales Terrace (Coral Habitat Of Particular Concern), Laura Dell Aug 2018

A Comparison Of Benthic Habitats And Faunas Between The Miami Terrace (Proposed Calypso Pipeline Site) And The Pourtales Terrace (Coral Habitat Of Particular Concern), Laura Dell

HCNSO Student Theses and Dissertations

Quantitative photographs of benthic communities at two northern Miami Terrace sites, originally investigated as part of an environmental impact survey in advance of the proposed Calypso pipeline, and two Pourtalès Terrace sites, investigated as part of an exploration of deep-sea coral and sponge ecosystems (DSCEs) within the Pourtalès Terrace Deep-water Coral Habitat Area of Particular Concern (CHAPC), were reanalyzed and compared for similarities and differences. Both terraces are part of an elongated lithified platform that parallels the southeastern Florida coast at depths averaging between 250 and 450 m. Although both sites have similar geological origins and lie under the Florida …


Next Generation Sequencing Methods For Coastal Zone Water Quality Monitoring, Catherine Iskrenko Aug 2018

Next Generation Sequencing Methods For Coastal Zone Water Quality Monitoring, Catherine Iskrenko

HCNSO Student Capstones

When analyzing the water quality of the coastal zone, culture-based techniques have been utilized most often to identify Fecal Indicator Bacteria in samples. Since the advent of the Sanger Method for DNA sequencing, other techniques have arisen that provide significantly more information on the microorganisms in sample, but they are still not the mainstream for water quality analysis. This capstone reviews and compares culture-based techniques, DNA sequencing, RNA sequencing, qPCR for biomarker, and 16S rDNA sequencing to highlight their merits and shortcomings for analyzing environmental water samples. The technique presented that provides the broadest range of information (including the identification …


Meta-Analytic Summary Of Parasites And Diseases Of Elasmobranchs Found In Florida Waters, Alexis S. Modzelesky Aug 2018

Meta-Analytic Summary Of Parasites And Diseases Of Elasmobranchs Found In Florida Waters, Alexis S. Modzelesky

HCNSO Student Capstones

Elasmobranchs have conservational and commercial importance. There is a need for a more complete understanding of their health, due to their ability to shape trophic webs and their money-making potential with fishers and ecotourists. Sharks have been known to influence the strength of food webs, including reef ecosystems where many fish species are harvested for food. The investigation of pathogenic agents and diseases in elasmobranchs has been biased to favor those natural enemies that inhabit the digestive system and epidermal surfaces. Certain groups of parasites such as cestodes, copepods, and monogeneans, were most often recorded in this study. The bacterial …


Microbial Ecology Of South Florida Surface Waters: Examining The Potential For Anthropogenic Influences, Chase P. Donnelly Aug 2018

Microbial Ecology Of South Florida Surface Waters: Examining The Potential For Anthropogenic Influences, Chase P. Donnelly

HCNSO Student Theses and Dissertations

South Florida contains one of the largest subtropical wetlands in the world, and yet not much is known about the microbes that live in these surface waters. These microbes play an important role in chemical cycling and maintaining good water quality for both human and ecosystem health. The hydrology of Florida’s surface waters is tightly regulated with the use of canal and levee systems run by the US Army Corps of Engineers and The South Florida Water Management District. These canals run through the Everglades, agriculture, and urban environments to control water levels in Lake Okeechobee, the Water Conservation Areas, …

Marine & Environmental Sciences Faculty Articles

Benthic ctenophores, members of the family Coeloplanidae (Order Platyctenida, Phylum Ctenophora) are more widespread and abundant in tropical and subtropical marine environments than formerly recognized. Coeloplanid ctenophores are members of the most speciose family of benthic ctenophores, with 33 recognized species of Coeloplana and one species of the genus Vallicula (Mills 1998). The majority of coeloplanids are ectosymbionts of algae and diverse benthic invertebrates (Matsumoto 1999, Alamaru et al. 2015). Hundreds to thousands of individuals can occupy preferred habitats in < 1 m2 of substrate patches. Galt (1998) noted Vallicula multiformis inhabiting algae in Hawaii at population densities as high as 10,000 …

Using Facebook to create a participatory, arts-based online focus group, this study had two primary purposes: (1) to examine how mothers in academia present themselves as they transition from doctoral student mother (“DocMama”) to full time position as motherscholars and (2) to explore the use of a participatory, arts-based online focus group on Facebook to facilitate participant description of experiences and feelings. This study adds both to the research on online research by emphasizing a collaborative nature and art to share experiences, and also to the research about motherscholars, examining the oft overlooked transition from doctoral program to academic career …


Parasitic Indicators Of Foraging Strategies In Wading Birds, Sarah Gumbleton Jul 2018

Parasitic Indicators Of Foraging Strategies In Wading Birds, Sarah Gumbleton

HCNSO Student Theses and Dissertations

Feeding ecology and trophic interactions of six species of wading birds were explored through a combined analysis of stable isotope profiles and endoparasite communities. Stable isotopes broadly characterize the feeding preferences and geographic information, while parasite communities reflect long-term trends in feeding ecology. Deceased birds were obtained from four South Florida wildlife rehabilitation organizations. Of the 81 birds dissected, 73 contained parasites. Parasites were predominately found within the gastrointestinal tract. Host and range extensions were noted for several parasite taxa. Bird host species had a significant effect on the parasite community (P=0.001) while wildlife center location and maturity status did …

Little is known about pain and pain management in older adults who experience open reduction and internal fixation (ORIF) surgery. This qualitative descriptive phenomenological study explored two research questions: (a) What are the perceptions of pain and pain management in patients between 65 and 75 years of age, 48 hours after ORIF surgery in a community hospital? (b) What are the perceptions of adaptation after ORIF? A pilot study included four patients in two units of a Southern California hospital, followed by open ended, semi-structured interviews with 10 participants. Four themes emerged: (a) elderly patients experience different patterns of pain …


Visual Inspection Of Sequential Data: A Research Instrument For Qualitative Data Analysis, Alaa A. Aldahdouh Jul 2018

Visual Inspection Of Sequential Data: A Research Instrument For Qualitative Data Analysis, Alaa A. Aldahdouh

The Qualitative Report

Sequence analysis has been widely used to investigate the patterns of similarities and differences of sequential data in biology and sociology. However, the debate on the usage of sequence analysis in social sciences has not been settled yet. Among a long list, sequence analysis methods have been criticized for ignoring the qualitative information behind the sequences. This paper presents a new instrument for inspecting sequential data visually in qualitative studies. The method includes building a hierarchical tree of relations among the categories which is then used to recode the categories systematically. The recoding process is meant to give meaning to …

We assessed calling of SNPs, indels, copy number variation, and the speed of WGS throughput promised. Twenty separate QC analyses showed high similarities among the sequence quality and called genotypes. The ten genomes tested by the centers included eight …


Spatiotemporal Change In The Benthic Community Of Southeast Florida, Nicholas P. Jones Jul 2018

Spatiotemporal Change In The Benthic Community Of Southeast Florida, Nicholas P. Jones

HCNSO Student Theses and Dissertations

High-latitude reefs have been postulated as refugia, centers for resilience or the first areas to undergo re-organization under climate change. The Southeast Florida Reef Tract (SEFRT) is a high-latitude reef system (>25 °N) running parallel to the highly urbanized coastline of southeast Florida. With a benthic community comprised of a mixture of coral reef associated assemblages, the SEFRT is towards the northern limit of stony coral cover due to temperature constraints. This study analyzed spatial variations in benthic cover, spatiotemporal changes in the benthic community and the impact of spatial and temporal fluctuations in temperature on benthic cover on …

Dental calculus (calcified dental plaque) is prevalent in archaeological skeletal collections and is a rich source of oral microbiome and host-derived ancient biomolecules. Recently, it has been proposed that dental calculus may provide a more robust environment for DNA preservation than other skeletal remains, but this has not been systematically tested. In this study, shotgun-sequenced data from paired dental calculus and dentin samples from 48 globally distributed individuals are compared using a metagenomic approach. Overall, we find DNA from dental calculus is consistently more abundant and less contaminated than DNA from dentin. The majority of DNA in dental calculus is …

Ongoing Transposon-Mediated Genome Reduction In The Luminous Bacterial Symbionts Of Deep-Sea Ceratioid Anglerfishes, Tory Hendry, Lindsay L. Freed, Dana Fadera, Dante Fenolio, Tracey Sutton, Jose Lopez

Marine & Environmental Sciences Faculty Articles

Diverse marine fish and squid form symbiotic associations with extracellular bioluminescent bacteria. These symbionts are typically free-living bacteria with large genomes, but one known lineage of symbionts has undergone genomic reduction and evolution of host dependence. It is not known why distinct evolutionary trajectories have occurred among different luminous symbionts, and not all known lineages previously had genome sequences available. In order to better understand patterns of evolution across diverse bioluminescent symbionts, we de novo sequenced the genomes of bacteria from a poorly studied interaction, the extracellular symbionts from the “lures” of deep-sea ceratioid anglerfishes. Deep-sea anglerfish symbiont genomes are …

Past, Present, And Future: Narrative Reflections Of A Novice Researcher, Katie L. Laux

The Qualitative Report

In this article, I use an autoethnographical approach to explore how I identified my research interests of student voice, action research, and students as scientific researchers. My purpose was to identify some of the influences on my academic life. To achieve this goal, I used my writing as a method of both data collection and analysis combined with my parents’ interpretations of events to create narratives of my lived experiences. This process allowed me to make sense of how my lived experiences shaped my decision to become a doctoral student and the choices I have made as a novice researcher.


Characterization Of The Bioluminescent Symbionts From Ceratioids Collected In The Gulf Of Mexico, Lindsay L. Freed Jun 2018

Characterization Of The Bioluminescent Symbionts From Ceratioids Collected In The Gulf Of Mexico, Lindsay L. Freed

HCNSO Student Theses and Dissertations

Anglerfishes are easily one of the most popular deep-sea creatures due to their menacing appearance, extreme sexual dimorphism, parasitic mating approach, and eye catching bioluminescent lure. Unlike most bioluminescent fishes, which intrinsically generate light, female anglerfishes belonging to nine of the 11 families within the suborder Ceratioidei (deep-sea anglerfishes) have developed a symbiotic relationship with bioluminescent bacteria that are housed within the light organs. Previous molecular work had identified symbionts from two anglerfish species as novel and possibly unculturable taxa (Haygood et al., 1992), but nothing more has been revealed about the bioluminecent symbionts of ceratioids. As part of …

Hypocrisy And Corruption: How Disparities In Power Shape The Evolution Of Social Control, Omar T. Eldakar, J. Oliver Kammeyer, Nikhil Nagabandi, Andrew C. Gallup

Biology Faculty Articles

Altruism presents an evolutionary paradox, as altruistic individuals are good for the group yet vulnerable to exploitation by selfish individuals. One mechanism that can effectively curtail selfishness within groups is punishment. Here, we show in an evolutionary game-theoretical model that punishment can effectively evolve and maintain high levels of altruism in the population, yet not all punishment strategies were equally virtuous. Unlike typical models of social evolution, we explicitly altered the extent to which individuals vary in their power over others, such that powerful individuals can more readily punish and escape the punishment of others. Two primary findings emerged. Under …

We have previously reported the use of combinatorial chemistry to identify broad-spectrum antibacterial agents. Herein, we extend our analysis of this technology toward the discovery of anti-resistance molecules, focusing on efflux pump inhibitors. Using high-throughput screening against multi-drug resistant Pseudomonas aeruginosa, we identified a polyamine scaffold that demonstrated strong efflux pump inhibition without possessing antibacterial effects. We determined that these molecules were most effective with an amine functionality at R1 and benzene functionalities at R2 and R3. From a library of 188 compounds, we studied the properties of 5 lead agents in detail, observing a fivefold to eightfold decrease …


Heavy Metal Accumulation In Seagrasses In Southeastern Florida, Erin Smith Jun 2018

Heavy Metal Accumulation In Seagrasses In Southeastern Florida, Erin Smith

HCNSO Student Theses and Dissertations

Seagrass beds are among the most ecologically important systems in the marine environment. They provide the primary production to nearby coral reef and mangrove communities, and seagrasses comprise a large component of the diets of many marine organisms including fishes, small invertebrate species, and many protected species such as manatees and sea turtles. This consumption provides a pathway for many contaminants to enter the marine food web via the seagrasses. The coastal location of seagrass beds causes them to be especially susceptible to anthropogenic pollution, including accumulation of heavy metals, which has been shown to have many adverse health effects …
