- Abstract/Description
-
The composition of marine bacterial communities from South Florida beaches were characterized using 16S rRNA sequence analysis. To compare cultivable and noncultured populations, community genomic DNA was extracted directly from sand and seawater samples and from two cultured equivalents. Only two ofthe 86 (2.3%) direct extracted sequences and 79 of 150 (52.6%) culture sequences belong to known isolates in Ribosomal Database (version 9.0) at 95% confidence level. At low stringency (p=0.70),...
Show moreThe composition of marine bacterial communities from South Florida beaches were characterized using 16S rRNA sequence analysis. To compare cultivable and noncultured populations, community genomic DNA was extracted directly from sand and seawater samples and from two cultured equivalents. Only two ofthe 86 (2.3%) direct extracted sequences and 79 of 150 (52.6%) culture sequences belong to known isolates in Ribosomal Database (version 9.0) at 95% confidence level. At low stringency (p=0.70), the populations cluster into several unknown clads with early divergence, indicating the presence of novel well established bacterial groups. Members of phylum Bacteroidetes, Firmicuites and Proteobacteria were identified, with the latter being the most prevalent in culture. Diversity indices rank Hollywood beach > Fort Lauderdale > Hobie beach. Taxonomic representation indicates marine water as more diverse compared to dry sand and wet sand. A combination of phylogenetic markers will be needed to define the immense diversity of this niche.

Show moreThe octocoral Eunicea fusca is the source of important anti-inflammatory compounds such as the diterpenes fuscol and the fuscosides. Evidence suggests that these compounds are being produce by bacterial sources that live in symbiosis with the coral. As part of an investigation to better understand the role of bacteria associated with E. fusca , the characterization of the bacterial community using two different techniques (culture dependent technique and culture independent technique) and sea water samples was done. Sea water samples were used as a control to determine how closely associated bacteria are to this octocoral. The polymerase chain reaction (PCR) with universal bacterial primers FC27 and RC 1492 specific to prokaryotic 16S rDNA gene sequences was used to characterize the total bacterial population when using both the culturable and the non-culturable approaches. The results indicate a diverse group of bacteria associated to E. fusca composed of 10 different groups. The pro teo bacteria group was the most predominant group when both techniques were used. The a-proteobacteria represented the highest percentage of bacteria associated to E. fusca.

Show moreForest ecosystems are critically important to biodiversity and the global carbon budget. Within forest ecosystems, dead wood has several ecological roles, including in carbon and nutrient dynamics and biodiversity conservation. However, surface fuels in forests also influence wildfire behavior and associated risks and hazards. Therefore, appropriate management of dead wood contributes directly to appropriate functioning of the forest ecosystem by conserving forest biodiversity, mitigating extreme wildfire events and pyrogenic emissions, and enhancing carbon sequestration. Using data extracted from peer-reviewed journal articles, geospatial, and field inventory data, and integrating meta-analytic, hierarchical regression, and vegetation simulation modeling approaches, this dissertation project examined the influence of dead wood on biodiversity, carbon, and wildfires in forest ecosystems. The meta-analysis results suggest that dead wood quantity is an indicator of forest biodiversity, while dead wood types and decay stages had varied relationships with biodiversity. Generalized linear and additive mixed effects modeling of geospatial and human observed data demonstrated the predominant influences of weather conditions and moderate effects of live and dead fuels on exceptionally large wildfires’ behavior in the western United States. Consistently dominant effects of temperature on wildfire behavior highlight and emphasize the pressing need to address climate change's impact on western US forests. Lastly, vegetation and wildfire simulation modeling of forest stand inventory data and post-modeling carbon computations suggested that physical harvesting of dead wood, an approach analogous to traditional practice of firewood collection, when combined with modern mechanical fuel reduction treatments in Sierra Nevada, CA, mixed conifer forests has great potential to mitigate wildfire hazards, reduce fire emissions, and enhance carbon sequestration.

Woods Hole Oceanographic Institution conducted two cruises to explore the New England Seamount chain in 2003. This study assessed fish species throughout Alvin submersible dives during these 2003 cruises. Digital video footage was converted to still photographs and video clips using the Macintosh movie program iMovie. Fishes were identified to the lowest possible taxonomic level using keys and literature. The habitat, depth and behavior of observed fishes were compared to the literature available. Geographical distributions of the species were considered. I assessed substrate preference by building a chart that reflects the different sediment regimes that fishes were found on. In all I identified 317 individuals representing 33 different taxa, including two species with new habitat range information Neocyttus helgae and Lepidion sp.

Show moreLoggerhead (Caretta caretta) and green (Chelonia mydas) turtles recruit to nearshore environments as juveniles. These often degraded habitats are associated with emerging diseases such as green turtle fibropapillomatosis (GTFP), however there are few studies on immune function in sea turtles. The objective of this research was to quantify phagocytosis of the innate immune system by flow cytometry and compare levels between animals from a degraded habitat (the Indian River Lagoon, FL) to a more pristine environment (the Trident Basin, Port Canaveral, FL), and across a range of temperatures. While in vitro temperatures did not alter rates of phagocytosis, it was higher in samples obtained in the summer than winter. Rates of phagocytosis in sea turtles with GTFP and from degraded environments with increased prevalence of GTFP were low compared to animals from the more pristine environment, suggesting that the environment can alter innate immunological function and thus contribute to the development of disease.

Show moreUnderstanding the link between indicator species and their environment is imperative to managing and conserving anthropogenically-altered ecosystems. Seasonally-pulsed wetlands are uniquely complex ecosystem where water-level fluctuations shape trophic interactions. Anthropogenic manipulation of water-level fluctuation threatens the integrity of these systems worldwide. Wading birds, a group of species sensitive to landuse changes and fluctuating habitat conditions, serve as important indicators for wetland health. I used wading birds in the Everglades, as a model system to address the challenges of environmental restoration within an ecosystem heavily impacted by anthropogenic activities. Specifically, I 1) identified the nesting response of Great Egret (Ardea alba), White Ibis (Eudocimus albus), and Wood Stork (Mycteria americana) to hydrologically-mediated changes in food availability and 2) quantified spatiotemporal foraging-habitat selection of Great Egrets, White Ibis, and Wood Storks to fluctuating hydrologic conditions. Collectively, model selection results suggest food availability, generated through dynamic hydrological conditions, is a strong predictor of the abundance of nesting birds in a given year. Great egret and white ibis produce the highest nests numbers in years when the frequency of days of rising water is low. Wood stork nest numbers are the highest in years with high prey production coupled with continuous prey availability. My study of resource selection indicated wading birds select foraging sites based on similar hydrologic parameters, but the response varies by species. Wood storks are more likely to forage in shallow cells (< 10 cm) drying with high recession rates (0.5-1.5 cm/day), and long time since last drydown (600 days). White ibises selected foraging cells with relatively shallow water depths (0-15 cm), intermediate recession rates (0.5-1.0 cm/day), and long time since drydown (600 days). Great egrets selected foraging cells with a wider range of water depths (0-20 cm) where recession rates were lower (0.5 cm/day). All species are more likely to forage in cells where water has not increased by more than 3 cm in the previous two weeks. These differences in resource selections correspond to morphological and behavioral differences in the species, whereby wood storks were more constrained hydrologically and would be more affected by water-level manipulation.
