Title: Pigment-based chemotaxonomy of phytoplankton in Lake Okeechobee, Florida and effects of irradiance on cyanobacteria.
Creator: Skoog, Kathryn Owen., Florida Atlantic University, Louda, J. William
Abstract/Description: The phytoplankton community of Lake Okeechobee, Florida, has been studied and algal divisions were identified. Chemotaxonomy is a process that assigns taxonomic divisions based on ratios of biomarker pigments to chlorophyll, as measured by high performance liquid chromatography (HPLC). Microscopic counts of taxonomic groups were compared to chemotaxonomic groups for lake samples for one year. Lab cultures of cyanobacteria grown at irradiance of 2 to 500 micromoles photons m-2 s-1 (muEinsteins...
Show moreThe phytoplankton community of Lake Okeechobee, Florida, has been studied and algal divisions were identified. Chemotaxonomy is a process that assigns taxonomic divisions based on ratios of biomarker pigments to chlorophyll, as measured by high performance liquid chromatography (HPLC). Microscopic counts of taxonomic groups were compared to chemotaxonomic groups for lake samples for one year. Lab cultures of cyanobacteria grown at irradiance of 2 to 500 micromoles photons m-2 s-1 (muEinsteins) suggested that internal ratios of chlorophyll to both zeaxanthin and echinenone could be used to estimate abundance of cyanobacteria, as either alone missed certain populations. Lake water samples showed that both methods agreed that diatoms and cyanobacteria were the dominant groups, with moderate number of green algae and few dinoflagellates. HPLC evidence revealed cryptophytes more frequently than did microscopy. This suggested that cryptophytes may be more significant than has been previously reported.

Title: An evaluation of methodology, dispersal and habitat usage of largemouth bass (Micropterus salmoides floridanus) from a supplemental stocking on Lake Okeechobee, Florida.
Creator: Jordan, Alyssa., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The largemouth bass (Micropterus salmoides) fishery was at an all time low on Lake Okeechobee when experimental supplemental stockings were done to try and enhance local bass populations. Largemouth bass had never been stocked on a large lake like Lake Okeechobee. The objectives were to develop a methodology, study dispersal, and compare stocked versus wild bass habitat choices. The methodology underwent considerable changes between studies. Bass dispersed to the edges by the second sampling...
Show moreThe largemouth bass (Micropterus salmoides) fishery was at an all time low on Lake Okeechobee when experimental supplemental stockings were done to try and enhance local bass populations. Largemouth bass had never been stocked on a large lake like Lake Okeechobee. The objectives were to develop a methodology, study dispersal, and compare stocked versus wild bass habitat choices. The methodology underwent considerable changes between studies. Bass dispersed to the edges by the second sampling period, so a larger sampling area may be needed. Water depth and pH were found to be significantly different between wild and stocked bass. Hatchery bass are naèive about predators, which may have resulted in stocked bass not moving to shallower areas like wild bass. The pH was weakly correlated with depth, so differences may be partially due to the fact that as depth increases, pH may also increase.

Title: Investigating a Cryptic Iron-Nitrogen Cycle in Lake Okeechobee Sediments`.
Creator: Silvera, Owen, Beckler, Jordon, Florida Atlantic University, Department of Marine Science and Oceanography, Charles E. Schmidt College of Science
Abstract/Description: The overall objective was to elucidate the effect of iron (Fe) on nitrogen (N) diagenesis in Lake Okeechobee. Somewhat counterintuitively, sediment ammonium (NH+4) inventories decreased during algal growth as dissolved organic nitrogen (DON) inventories increased. Whole core incubations were staged for denitrification experiments using isotopic N tracer. Core incubations showed the percentage of sediment N removal increase between summer (25 ± 21 %) and winter (39 ± 13 %). The amendment of...
Show moreThe overall objective was to elucidate the effect of iron (Fe) on nitrogen (N) diagenesis in Lake Okeechobee. Somewhat counterintuitively, sediment ammonium (NH+4) inventories decreased during algal growth as dissolved organic nitrogen (DON) inventories increased. Whole core incubations were staged for denitrification experiments using isotopic N tracer. Core incubations showed the percentage of sediment N removal increase between summer (25 ± 21 %) and winter (39 ± 13 %). The amendment of Fe2+ enhanced this seasonal effect likely via dissimilatory nitrate reduction to ammonium (DNRA). The isotopic signature of N2 flux also suggested an additional, sedimentary, N2 source via Fe coupled anaerobic oxidation of ammonium (feammox). Sediment slurry incubations supported the occurrence of both DNRA and feammox, showing first that nitrate (NO3−) was converted to NH4+ via DNRA, which contributed 23-26% of overall NO3− reduction. Fe amendment in slurries similarly stimulated the feammox process. However, aged Fe minerals accumulated linearly with N bound to Fe (Fe-N) in a subseasonal sediment time series, suggesting Fe-organic matter aggregation may lower the sediment NH4+ equilibrium concentration and benthic flux.

Title: Sedimentary characteristics of Sugar Ridge and their implications for sediment transport in Lake Okeechobee, Florida.
Creator: Badiali, Matthew Joel., Florida Atlantic University, Gallagher, Jacqueline
Abstract/Description: Lake Okeechobee is one of the largest lakes in the United States, yet its formation, circulation, and geomorphology are not well known. The ridges that occur on the eastern and northern shorelines of the lake have not been studied. Sugar Ridge is the closest ridge to the lake on the central part of the eastern shoreline. It is composed of medium- to fine-grained quartz (sugar sand) sediments in a dynamic form, superimposed upon organic peat and muck layers. It contains centimeter-scale...
Show moreLake Okeechobee is one of the largest lakes in the United States, yet its formation, circulation, and geomorphology are not well known. The ridges that occur on the eastern and northern shorelines of the lake have not been studied. Sugar Ridge is the closest ridge to the lake on the central part of the eastern shoreline. It is composed of medium- to fine-grained quartz (sugar sand) sediments in a dynamic form, superimposed upon organic peat and muck layers. It contains centimeter-scale bedding that exhibits many sedimentary structures typical of an accretionary barrier beach. Wind waves are considered the most likely cause of transport of the clastic sediments to the study area. Variations in lake level and wind in the region are such that conditions were favorable for development primarily in the winter. That is when lake levels were high enough to reach the ridge and the winds were strong enough to cause waves to transport sediment. Sediment was transported from the mouth of the Kissimmee clockwise around the northern perimeter. However, today the lake is completely enclosed and its levels are constantly manipulated.

There are many missing values and out-liers in this data. To impute the missing values, three different methods are used: Nearby window average imputation, Jones imputation using Kalman filter, and EM algorithm imputation. To detect outliers and remove impacts, we use ARIMA models of time series. Innovational and additive outliers are considered. It turns out that EM algorithm imputation is the best method for our wind speed data set. After imputing missing values, detecting outliers and removing the impacts, we obtain the best models for all four stations. They are all in the form of seasonal ARIMA(2, 0, 0) x (1, 0, 0)24 for the hourly wind speed data.

A spatial analysis of environmental factors affecting the growth of Melaleuca quinquenervia is conducted, and an analysis of the validity of such statistical inferences for use in future decision making is examined. Results indicate that managed water levels inside Lake Okeechobee did indeed have an effect on the rate of growth of Melaleuca quinquenervia.

The objective of this thesis is to examine the factors affecting these regulatory relationships, and explore alternatives for resolving intergovernmental conflict. Several consensus building tools are examined, including Resource Planning and Management Committees as authorized by Chapter 380, Florida Statutes, as well as committees created through gubernatorial executive orders. By analyzing and comparing these tools, as well as theories of intergovernmental relations, this study will identify the best available method for fostering intergovernmental coordination in the Lake Okeechobee region and its surrounding areas.

I examined food availability and nesting habitat of wading birds in South Florida. Evaluating prey availability and prey used by two small heron species demonstrated the ability for small herons to maintain consistent diets through fluctuating environmental conditions, within and across different wetland types. Small herons may be able to cope with environmental changes by altering foraging locations and strategies. Regarding nesting habitat, man-made sites may provide habitat comparable to natural sites, at least in the short-term. The nest’s position can influence its susceptibility to increased temperatures and predators, particularly for. Climatic conditions such as rainfall can also impact nesting success by altering foraging conditions and fish behavior. Understanding the effects of hydrologic regimes on biota can have practical applications since ecosystems around the world share similar problems with competing demands for resources, and there is a concern for how use can affect the quality of the resource.

Here, I compared the reproductive responses of two ecologically similar species, Snowy Egret and Tricolored Heron, to foraging conditions influenced by water management and examined the effect of nestling island type on the reproductive success of three wading bird species. Reproductive responses to foraging conditions were broadly similar between Snowy Egrets and Tricolored Herons, however this study revealed specific-specific differences that could lead to different population dynamics in response to management over the long-term. I also found that these two species had lower productivity at spoil islands than marsh colonies, whereas Great Egret productivity did not vary by colony type. This study demonstrates the importance of establishing species-species relationships between productivity and environmental conditions

Title: INFLUENCE OF HYDROLOGICAL VARIATION ON WADING BIRD DIETS AND REPRODUCTION IN A LACUSTRINE WETLAND.
Creator: Essian, David A., Gawlik, Dale E., Florida Atlantic University, Department of Biological Sciences, Charles E. Schmidt College of Science
Abstract/Description: Wetlandscape topography creates spatial variation in hydroperiod, which in turn creates spatial variation in biotic communities. Such spatiotemporal variation occurs on a large scale in some of the most productive wetlands in the world, including those of south Florida, U.S.A. Wading birds (Pelicaniformes and Ciconiiformes) are iconic, top-level consumers of such ecosystems. Infrequent drying is necessary to maintain the primary nest substrate (Salix caroliniana), and prey availability is...
Show moreWetlandscape topography creates spatial variation in hydroperiod, which in turn creates spatial variation in biotic communities. Such spatiotemporal variation occurs on a large scale in some of the most productive wetlands in the world, including those of south Florida, U.S.A. Wading birds (Pelicaniformes and Ciconiiformes) are iconic, top-level consumers of such ecosystems. Infrequent drying is necessary to maintain the primary nest substrate (Salix caroliniana), and prey availability is regulated by production of prey biomass in the wet season and the subsequent concentration of prey biomass into shallow pools during the dry season. The goal of this dissertation was to explicitly model wading bird nest abundance and survival as functions of water-level fluctuations, which were spatially nested (i.e., the effects of water-level fluctuations that occurred over a large scale were measured separately from the effects of water-level fluctuations that occurred over a small scale). In Chapter 2, I modeled colony-specific effects of wetlandscape water level fluctuations on wading bird nest abundance. Modeling the response at the colony level allowed the inclusion of important parameters that cannot be measured at the wetlandscape scale. For instance, each colony had its own optimal range of lake stage, which depended on local topography. I used the models to predict cumulative nest abundance under six hydrologic scenarios that were based on potential water management actions at Lake Okeechobee. I found that increasing water levels at the lake would marginally benefit the Great Egret but would substantially reduce long-term Snowy Egret and White Ibis populations. In Chapter 3, I modelled spatiotemporal distributions of fish biomass density in Lake Okeechobee’s littoral zone as a function of hierarchically nested hydrological variables. These models were consistent with the dynamic landscape connectivity model previously described in the literature. I modified the models to predict a binomial response which could then be linked to wading bird foraging threshold. The model predictions were used to estimate the number of available patch days during the breeding season, which was highly correlated with the number of nests for the great egret (Ardea alba), the snowy egret (Egretta thula), and the white ibis (Eudocimus albus). In Chapter 4, I used spatial statistics to better understand how interannual variability in resource wave patterns in the littoral zone influenced wading bird nest abundance. I found that more birds nested in years when the drying edge of the marsh moved further across the landscape. Great egret nest survival increased also, but small heron nest survival decreased. This decrease was likely because small herons continued to nest late into the season in years with longer waves, and, as with most bird species, nests that are initiated later in the season. In Chapter 5, I compiled conventional nestling diet data from 5 wading bird species sampled in 4 wetland types from 2010 to 2020 (not every wetland type was sampled in every year). This chapter provides a comprehensive, broad description of wading bird diets in south Florida, and quantifies interspecies, spatial, and interannual variation in nestling diets. By using a model-based approach to quantify the relative biomass of prey species and prey traits in nestling diets, I provide the first diet analysis that is fully reproducible across the large sympatric range of the wading bird species in the study (great egret, snowy egret, tricolored heron [Egretta tricolor], little blue heron [Egretta caerulea], and wood stork [Mycteria americana]).

Ecological data assembled in many formats is very difficult to reuse. This thesis develops a database model that supports the storage of heterogeneous data in standardized formats. Ecological data standardization is solved with the specification of a structure conversion system. Because input formats cannot be predicted, a scientific data description language was created to control the execution of the conversion system. System analysis is based on interviews with South Florida Water Management District scientists conducting ecosystem research, and ecological data collected at Lake Okeechobee, Florida, during a five-year study. Object-oriented and structural methods were used for analysis. Development is complemented with an introduction to user interfaces.

Show moreWater samples from Lake Okeechobee, Florida have been analyzed in order to relate pigment fingerprints to temporal and spatial variations. Chemical taxonomic identification of predominant photoautotrophs was based on pigment profiles evolved from literature reports and analysis of specific cultures. Carotenoids and chlorophylls were analyzed using high performance liquid chromatography (HPLC) and ultra-violet visible spectra obtained with a photo diode array detector (PDA). Pigments were identified by coincident matches of retention time and UV/Visible spectral properties. Chemical taxonomic identification was determined by comparison with known photoautotrophic pigment 'fingerprints'. Experimental results show pigment arrays indicative of chromophytes, chlorophytes and cyanophytes as well as photoautotrophic bacteria present in Lake Okeechobee. The lake was also found to be heterogeneous and dynamic in terms of pigment composition. Major pigment groups changed as a function of location in the lake and as a function of season. A greater pigment diversity was found to exist in the benthos due to the presence of degradation products. HPLC-PDA pigment analysis for chemotaxonomic typing of photoautotrophic communities is attainable and can be used as a rapid viable alternative to microscopic examination of plankton and epiphyte samples. Also, taxonomic typing of organic matter and photoautotrophic communities of sediments, including bacterial populations, can be accomplished using this method.
