A brown tide bloom of the pelagophyte Aureoumbra lagunensis caused significant impacts to north Indian River Lagoon (IRL) in 2012-2013, including seagrass die-offs, fish kills, and reduced growth and grazing of ecologically important bivalves. There is potential for another pelagophyte, Aureococcus anophagefferens, to expand into this system. Filtration rates (FR) of the pleated tunicate Styela plicata exposed to Aureoumbra lagunensis and Aureococcus anophagefferens were measured against...
Show moreA brown tide bloom of the pelagophyte Aureoumbra lagunensis caused significant impacts to north Indian River Lagoon (IRL) in 2012-2013, including seagrass die-offs, fish kills, and reduced growth and grazing of ecologically important bivalves. There is potential for another pelagophyte, Aureococcus anophagefferens, to expand into this system. Filtration rates (FR) of the pleated tunicate Styela plicata exposed to Aureoumbra lagunensis and Aureococcus anophagefferens were measured against exposure to a control alga (Tisochrysis lutea) in order to determine its potential use as a bioremediator against these harmful algal blooms (HABs). In addition, whether S. plicata might serve as a vector of HABs was studied by culturing fecal deposits. Short-term exposure to HABs significantly reduced FR, whereas long-term exposure indicates comparable cell removal compared to the control. Vector potential of S. plicata was inconclusive. Results warrant further research to determine whether S. plicata can acclimate or respond to HAB conditions over time.

Show moreThe Indian River Lagoon (IRL) FL, USA, is an Estuary of National Significance due to its economic and high biodiversity. Microbial populations are understudied in the IRL despite their numerous ecological services. A two-year, nineteen-site Lagoon-Wide Survey (LWS) was conducted to provide the first 16S rRNA amplicon sequencing data on the microbiome of the sediment in the IRL and determine how the microbiome changed in response to environmental and anthropogenic factors. The most influential variables that explained the variability between microbiomes were porewater salinity, total organic matter (TOM), and copper (Cu). These results correlated with some of the anthropogenic pressures the IRL faces such as freshwater discharges from St. Lucie Estuary (SLE), trace metal contamination, and the accumulation of fine-grained, highly organic sediment known as “IRL muck” (muck). Research then focused on determining the microbial differences between three sets of sample types: sediment from the IRL versus the SLE; sediment that had three muck characteristics versus those with zero; and high TOM sediment that had high Cu versus high TOM sediment that had low Cu. Differentially abundant prokaryotes between sample types were determined with novel indicator analysis techniques. One technique tested the effectiveness of an indicator list to separate samples based upon the product of the sensitivity and specificity of partitioning around medoids clustering in comparison to metadata classifications. The other technique allowed for the tracking of changes in the entire indicator microbiome. These new indicator analysis techniques were created using the original LWS data and tested to determine how sediment microbiomes responded during two opportunistic surveys: dredging of muck from an IRL tributary (Eau Gallie River) and Hurricane Irma. These studies have filled the knowledge gap regarding the unknown microbiome of the IRL and how sediment microbiomes respond to extreme events such as dredging and a hurricane. They also led to the development of new indicator analysis techniques that can be used by to track changes in the entire indicator microbiome.

Very little is known about the Florida east coast diamondback terrapin (M. t. tequesta). This study examined wild terrapins in the central Indian River Lagoon to establish baseline population parameters for the species in this region. Morphometrics were assessed for the sampled animals, reinforcing findings of sexual dimorphism for the species. Acoustic monitoring was used to investigate terrapin occupancy and habitat use. Occupancy differed seasonally, with the highest occupancy in the summer and fall, lower occupancy in the spring, and the lowest occupancy in the winter. Terrapins were detected most commonly and spent a high percentage of their time in the southern portion of the study site. Reference blood chemistry values were established for the population. This study provided baseline information on a Species of Greatest Conservation Need in Florida.

Show moreSponges (Phylum Porifera) are hardy organisms persisting and predicted to become more dominant world-wide under climate change scenarios. However, we lack baseline knowledge on sponge biodiversity in transitional areas (subtropical to warm-temperate) that are more susceptible to climate change such as The Indian River Lagoon (IRL) (estuary) and Saint Lucie Reef (northern most coral reef) ecosystems in south Florida. The aims of this master’s thesis are to 1) evaluate if sponge assemblages reflect the previously defined ecotone between subtropical and warm-temperate biomes in the IRL (Chapter one), 2) determine how porifera communities are associated to their respective environment (temperature, water velocity, photosynthetically active radiation, carbonate chemistry, and nutrients) in the IRL and St. Lucie Reef (Chapter two), and 3) establish a distribution baseline for future studies aiming to assess Porifera range shifts during climate change (Chapter one and two). Porifera biodiversity surveys across the IRL and Saint Lucie reef were carried out at different spatial and time scales. Environmental parameters (ocean acidification, temperature and eutrophication) were obtained and compared for sites in Fort Pierce Inlet and St Lucie Reef. Chapter one results show that sponge assemblages do not reflect the previously defined ecotone between subtropical and warm-temperate biomes in the IRL, instead they structure in relation to the inlets (distance from the inlet). The most diverse sponge assemblages are found in Sebastian, Fort Pierce, and Jupiter Inlets, and are significant different among habitats; oyster reefs host a unique assemblage of excavating sponges.

Show moreEutrophication of urbanized estuaries is a global issue that continues to worsen as coastal development increases. The Indian River Lagoon (IRL) on Florida’s east-central coast is a eutrophic estuary that is experiencing harmful algal blooms of macroalgae and phytoplankton, as well as widespread seagrass losses. This is concerning as seagrasses provide many ecosystem services, including the provision of essential habitat. These alterations in benthic cover can have ecosystem level effects and require further investigation. Thus, drivers and effects of primary producer alterations in the IRL were investigated through analysis of long-term monitoring data, field surveys of faunal densities inhabiting macroalgae and bare bottom habitats, and stable nitrogen isotope (δ15N) analyses of primary producers, primary consumers, and secondary consumers. Long-term monitoring data from the northern IRL (NIRL) and Banana River Lagoon (BR) demonstrated there have been major seagrass losses coupled with increases in occurrence of the rhizophytic green macroalgae Caulerpa prolifera, which is now the dominant benthic cover in many locations. Multivariate analyses of long-term monitoring data spanning 2011-2020 suggested that the carbon to phosphorus ratio (C:P) of macroalgae is an important factor related to annual changes in benthic cover in the NIRL and BR; increased P-availability is correlated with these primary producer shifts. In situ collections of macroinvertebrates and resident fishes showed the current function and importance of macroalgae as habitat in the NIRL and BR, particularly in the relative absence of seagrass.
