Title: Examination of the Use of Floating Individuals of Halodule wrightii (Ascherson, 1868) for Restoration.
Creator: Berninger, Jacob J., Hanisak, M. Dennis, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The goal of this study was to develop an alternative approach to typical seagrass transplantation techniques that damage the donor bed. Floating individuals of Halodule wrightii were collected in the Indian River Lagoon (IRL), Florida, during fall of 2013 and spring of 2014, with the fall collection planted in outdoor tanks. Only 25% of individuals collected in the fall survived the winter in the tanks. Individuals from both collections were deployed onto biodegradable mats in a capped dredge...
Show moreThe goal of this study was to develop an alternative approach to typical seagrass transplantation techniques that damage the donor bed. Floating individuals of Halodule wrightii were collected in the Indian River Lagoon (IRL), Florida, during fall of 2013 and spring of 2014, with the fall collection planted in outdoor tanks. Only 25% of individuals collected in the fall survived the winter in the tanks. Individuals from both collections were deployed onto biodegradable mats in a capped dredge hole in the IRL in March, 2014. Approximately 66% of the mats survived the six-month experiment, and the area covered by seagrass quadrupled. Growth in shoot count, average height, horizontal spread, and biomass was similar for both fall and spring treatments. Thus, time and effort of overwintering had no benefit over spring harvesting. The use of floating individuals can provide a more practical, environmentally friendly alternative to traditional transplanting for seagrass re storation.

Title: The Role Of Disturbance In The Genotypic And Morphological Diversity Of Halodule Wrightii.
Creator: Tiling, Kathryn A., Proffitt, C. Edward, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: Seagrasses are important foundation species in coastal ecosystems. Genetic diversity of seagrasses can influence a number of ecological factors including, but not limited to, disturbance resistance and resilience. Seagrasses in the Indian River Lagoon (IRL), Florida are considered to be highly disturbed due to frequent events, like algal blooms, that impair water quality, reducing available light for seagrass growth.

Show moreSeagrasses are important foundation species in coastal ecosystems. Genetic diversity of seagrasses can influence a number of ecological factors including, but not limited to, disturbance resistance and resilience. Seagrasses in the Indian River Lagoon (IRL), Florida are considered to be highly disturbed due to frequent events, like algal blooms, that impair water quality, reducing available light for seagrass growth. Halodule wrightii is a dominant seagrass throughout the IRL, but its genetic diversity has only been quantified in a few Gulf of Mexico and Florida Bay populations and little is known about its potential ecological consequences. I quantified the genetic variation of H. wrightii using microsatellite markers in the southern IRL to determine: (i) how disturbance history influenced genetic diversity, (ii) if morphology of clones was, in part, genetically controlled and related to disturbance history, and (iii) if genotypes showed phenotypic plasticity in response to disturbances. In the IRL, H. wrightii populations exhibited moderate genetic diversity that varied with disturbance history. The disturbance history of a population was classified by the variance in the percent occurrence of H. wrightii over a 16-year period. Genotypic richness and clonal diversity of H. wrightii increased with increasing disturbance histories. Other genetic diversity measures (e.g., allelic richness, observed heterozygosity) did not change with disturbance history. These findings suggest that impacts to seagrass coverage over time can change the genotypic composition of populations. When different genotypes of H. wrightii were grown in a common garden, differences in leaf characteristics among genotypes provided evidence that morphological trait variation is, in part, explained by genetic variance. The disturbance history of genotypes did not directly affect morphological traits. However, significant genotype x site (within disturbance history) interactions found greater variation in shoot density and below ground traits of H. wrightii genotypes from sites of intermediate disturbance history. Traits of H. wrightii were shown to be phenotypically plastic. Significant genotype x environment interactions for shoot density and height demonstrated that genotypes responded differently by increasing, decreasing, and not changing sizes in response to light reduction. Genetic diversity of H. wrightii has strong implications for ecological function in coastal communities.

Title: An ecological study of photoautotrophs in Lake Worth.
Creator: Bolter, Keren P., Charles E. Schmidt College of Science, Department of Chemistry and Biochemistry
Abstract/Description: Little Lake Worth (LLW) (800 m x 200 m x 8« m) is an artificially deep, monomictic marine basin. Pigments and other water quality parameters (O2, pH, T, S, NO3 -. etc.) were utilized to characterize phototrophic communities and water quality. The water column is dominated by diatoms except in the hypolimnon during stratification events (late Summer) when strong anoxia and H2S favors abundant Chlorobium sulfur bacteria.

Show moreLittle Lake Worth (LLW) (800 m x 200 m x 8« m) is an artificially deep, monomictic marine basin. Pigments and other water quality parameters (O2, pH, T, S, NO3 -. etc.) were utilized to characterize phototrophic communities and water quality. The water column is dominated by diatoms except in the hypolimnon during stratification events (late Summer) when strong anoxia and H2S favors abundant Chlorobium sulfur bacteria. Results indicate nitrate-enriched freshwater baseflow indicative of septic tank seepage during the wet season. This also appears to lead to the accumulation of concentrated organic matter in the sediment. LLW is a potential threat to the health of the ecosystem and the humans using it recreationally. More research is required to verify the effectiveness of restoration options. The spatial and temporal distribution of Chlorobium (phaeovibiroides tent.) and their Bacteriochlorophyll-e homologues is described and compared to similar studies.

Title: Relationships Between Eutrophication and Acidification in the Indian River Lagoon.
Creator: Kaiser, Bret R., Lapointe, Brian E., Florida Atlantic University, Charles E. Schmidt College of Science, Center for Environmental Studies
Abstract/Description: In the eutrophic waters of the Indian River Lagoon (IRL), decreases in overall shellfish size have been reported, which may be related to coastal acidification. To understand the relationship between acidification and eutrophication, water samples from 20 sites spanning the IRL were collected and analyzed for dissolved nutrients and omega values in spring (dry season) and fall (wet season), 2016-2017. Additionally, three sites were sampled weekly to observe temporal variability of nutrients...

To understand the relationship between acidification and eutrophication, water samples from 20 sites spanning the IRL were collected and analyzed for dissolved nutrients and omega values in spring (dry season) and fall (wet season), 2016-2017. Additionally, three sites were sampled weekly to observe temporal variability of nutrients and omega values. For the IRL-Wide sampling, sites with higher dissolved nutrient concentrations showed lower omega values with significant negative relationships. Both sampling programs showed an overall positive linear relationship between salinity and omega values. This work suggests that salinity and dissolved nutrients have implications for acidification in the IRL and must be considered for future water quality, shellfish and coral reef restoration.

Title: Oranges and inlets: an environmental history of Florida's Indian River Lagoon.

Abstract/Description: Nineteenth century settlers in Florida's Indian River Lagoon (IRL) region created an isolated fringe culture wholly dependent on the instable hydrological forces of the shallow lagoon system. These settlers were among the first to construct a built environment market by the dredging and filling that would define much of the twentieth century Sunshine State.

Show moreNineteenth century settlers in Florida's Indian River Lagoon (IRL) region created an isolated fringe culture wholly dependent on the instable hydrological forces of the shallow lagoon system. These settlers were among the first to construct a built environment market by the dredging and filling that would define much of the twentieth century Sunshine State. There has been no period when the liminal IRL ecosystem was not without shifting barrier islands and dramatically varying salinity levels due primarily to the oceanic interchange following the opening and closing of natural inlets. This paper suggests that attempts to "restore" the lagoon will necessarily declare an arbitrary historical form to be normative for the system. The first and last chapters provide an overview of the system's origins and recent history, while the core of the paper focuses on human-environment interaction of the lagoon in the late nineteenth and early twentieth century.

Title: Monitoring seasonal and annual changes in the mesozooplankton community of the Indian River Lagoon, Florida.
Creator: Kerr, Miranda Hoover., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: In estuaries, like the Indian River Lagoon, mesozooplankton have a vital role in the food web by connecting trophic levels. In this study, mesozooplankton abundance and species composition were monitored weekly on the incoming and outgoing tides from September 2006 to May 2009. For the incoming tide, the mean abundance was 2298.2 mesozooplankton/m3 (+/-325.2), and for the outgoing tide the mean abundance was 1180.0 mesozooplankton/m3 (+/-153.1). The mesozooplankton abundance on the incoming...

For the incoming tide, the mean abundance was 2298.2 mesozooplankton/m3 (+/-325.2), and for the outgoing tide the mean abundance was 1180.0 mesozooplankton/m3 (+/-153.1). The mesozooplankton abundance on the incoming tide was significantly greater than on the outgoing tide. The most abundant type of mesozooplankton was the copepod Acartia tonsa, representing 35.0% and 52.1% of the individuals on the incoming and outgoing tides respectively. Mesozooplankton abundance values were compared with environmental data obtained from the South Florida Water Management District. The strongest positive correlation was found between chlorophyll a concentrations and A. tonsa abundance, likely due to phytoplankton being the primary food source for A. tonsa.

Show moreSorites dominicensis is a common Foraminifera living on Thalassia testudinum seagrass blades in the Indian River Lagoon. This locality is unique because epiphytic diatoms, characteristic of Caribbean and temperate environments, are expected to make up the biofilm community. Diatoms compose a large part of the Foraminiferan diet. It is important to understand the cause and effect relationship of population variation between S. dominicensis and its preferred food source, since both are valuable bioindicators. We examined the selective feeding of S. dominicensis by first, identifying the diatom assemblage. Second, we utilized scanning electron microscopy (SEM) in order to identifying the remains of diatoms entrapped in pseudopodial nets and in debris piles. We found that Mastogloia and Cocconeis were the most prominent genera in the overall diatom assemblage. The food preference of S. dominicensis included Amphora, Berkeleya rutilans,Cocconeis, Licmophora dalmatica, Mastogloia, Odontella rhombus, Plagiogramma pulchellum var. pygmaeum, and Skeletonema.

Little is known about nitrogen (N) and phosphorus (P) limitation or the importance of morphological/physiological characteristics of bloom-forming macroalgae (Ulva lactuca, Hypnea musciformis, and Gracilaria tikvahiae) in the IRL. We hypothesized: 1) all species would proliferate in nutrient-rich Titusville, 2) opportunistic U. lactuca would dominate, 3) Rapid Light Curves (RLCs) would assess nutrient status, and 4) nutrient concentrations would regulate growth more than N:P ratios. Field studies showed rapid biomass doubling times of 2 days (U. lactuca; November 2012) in urbanized Titusville. RLCs in a guano-enriched island off Big Pine Key (BPK) and Titusville (Ulva spp.) were similar due to P-saturation. Laboratory studies showed three-fold higher RLCs and two-fold faster growth at high nutrient concentrations of N and P. Reductions of both N and P will be required to moderate future blooms.
