▼ Heavy metal pollution is a widespread environmental problem worldwide. In the USA, ~80% of superfund sites are contaminated with toxic heavy metals including mercury. Mercury (Hg) is of serious concern due to its strong ability to bio-accumulate and bio-magnify in food chains and its adverse impacts on living organisms. Unfortunately, the development of cost-effective and environmental-friendly remediation techniques for Hg-contaminated soils remains challenging. In this study, a readily available waste material with little to no adverse effects on soils, the aluminum based drinking water treatment residuals (Al-WTRs), is evaluated for use in the immobilization of Hg in contaminated soils. In a first set of experiments a combination of selective sequential extraction (SSE), X-ray photoelectron spectroscopy (XPS), X-ray diffraction spectroscopy, energy dispersive spectroscopy (EDS) and solid phase thermal decomposition (SPTD) techniques were used to investigate solid-phase Hg formed by reacting aqueous Hg solutions with Al-based adsorbents to identify the different sites of Hg sorption in Al-WTRs. Results from these analyses willconfirm if mercury immobilization by Al-WTR occurs due to predominantly Hgsorption onto amorphous aluminum oxy-hydroxides, the main components of Al-WTR’s, in order to understand the long-term stability of Hg–(Al-WTR)complexes formed. In addition columns leaching experiments were performed to study the effect of fluctuating pH and dissolve organic matter on the stability of formed Hg–(Al-WTR) complexes. Preliminary results show that: (1) Al-WTR successfully immobilizes the water soluble and easily exchangeable soil-Hg fractions and Hg forms strong and stable complexes with Al-WTRs; (2) the presence of dissolved organic matter in the leaching solution decreases the ability of Al-WTR to adsorb Hg released from soil particles, due to the high affinity of Hg for organic ligands; and (3) soil Hg speciation dictates the need and efficiency of Al-WTRs. Additionally, treated and non-treated Hg-contaminated soils were incubated under anoxic conditions to assess the potential of Al-WTR to limit methyl-Hg production, which is used here as asurrogate for Hg bioavailability to Hg-methylating microorganisms. Based on preliminary data we expect mercury will have minimal desorption from Al-WTR complexes under anoxic conditions, limiting its bioavailability to microorganisms and transformation into more toxic forms.

▼ Regional curves, which relate bankfull discharge and channel geometry (cross-sectional area, width, and mean depth) to drainage area in regions of similar climate, geology, and vegetation, have greatly aided in creating target natural channel designs for stream restoration efforts. Regional curves were developed for peninsular Florida based on cross-sectional and longitudinal survey data collected at 17 gaged and 28 ungaged as near-to-natural streams, ranging in drainage area from 0.2 to 311 square miles and valley slope from 0.02 to 2.27%. Based on an analysis of prevalence among sites, slopes, and hydrologic data, the elevation of the flat floodplain was determined to be the most reliable bankfull indicator at sites with a wetland floodplain, while the elevation of the inflection on the bank was the most reliable indicator at sites with an upland floodplain. Analysis of bankfull indicator slopes further revealed that a water slope threshold of approximately 0.5% exists, above which bankfull indicators appear to more reliable, suggesting that slope-area techniques for calculating the bankfull discharge may be unreliable in peninsular Florida streams with a water slope less than 0.5%. The dataset was further divided based on physiography (flatwoods versus highlands), geography (northern versus southern peninsula), and floodplain types (wetland versus upland and cypress-dominated versus non-cypress-dominated) to determine if significant differences exist in the bankfull regressions and/or various dimensionless ratios (sinuosity, width-to-depth, maximum depth-to-mean depth, valley slope, and maximum discharge-to-mean annual discharge) among various peninsular Florida stream subsets. Streams with wetland floodplains were found to have a significantly greater bankfull area and bankfull width than streams with an upland floodplain. Also, streams with cypress-dominated floodplains had a greater width-to-depth ratio than streams with non-cypress-dominated floodplains. Further, streams draining flatwoods physiographies were found to be flashier. These differences may be important considerations when designing natural channels in peninsular Florida. Annual peak flow data for the gaged sites were analyzed to estimate the bankfull discharge return interval using Log Pearson Type III distributions. The bankfull discharge ranged from less than one year to 1.44 years, which is more frequent than the average 1.5-year return interval often cited in the literature. Based on analysis of the flow duration at gaged sites, bankfull discharge for peninsular Florida streams is equaled or exceeded approximately 21% of the time on average, or about 77 days per year. On average, the bankfull discharge is roughly four times that of the mean annual discharge and is 35% of the 1.5-year discharge. Lastly, the regional curves developed for peninsular Florida were compared to regional curves previously developed for other regions of the southeastern United States Coastal Plain. Peninsular Florida bankfull channels were found to have a lower… Advisors/Committee Members: Wise, William R. (committee chair), Crisman, Thomas L. (committee member).

▼ The Apalachicola River has the greatest discharge of any river in the State of Florida, and has one of the largest forested floodplains of any river in the southeastern US. Rapid urbanization of the upper ACF basin, as well as several extensive droughts in the region have resulted in increased demands for water withdrawals and flow regulation for municipal, commercial, and agricultural uses throughout the basin. This has positioned the states of Florida, Georgia, and Alabama, along with several federal agencies, in a surface water allocation and management conflict. Of particular concern are minimum flows and levels required to maintain healthy biotic communities during periods of regional drought, when water demands are at their highest, and the resource is most limited. Very low flows confine the primarily sandy-bottomed Apalachicola River to its main channel, where snags serve as the only stable structural habitat for the riverine fauna. This study aimed to assess the ecological importance, and quantify the amount of snags submerged in the Apalachicola River as a result of variations in flow regime. Additionally, the distributions of snags based on river-bank habitat and geomorphological characteristics were also examined to assess their role in snag habitat availability. Traditional aquatic snag quantification methods were not feasible in the exceedingly turbid, high-order Coastal Plain river; therefore, a novel method using digital imaging analysis techniques was developed for analysis. Area and percentage of available snag habitat submerged were analyzed at 0.5-m elevations above water level for 60 sampling stations along the Apalachicola River at a relatively-low river discharge. Snag area values generated using the novel methods presented in this study were credible for steep sloping bank, gentle sloping bank and dike field habitat types, but were erroneously-elevated for sandbar stations. Snag quantities of non-sandbar stations were found to be greatest within the first 1.0 m of exposed bank for nearly all sites surveyed, while steep sloping banks typically exhibited the most uniform vertical snag distribution. In most cases, geomorphic classifications demonstrated no considerable effect on non-sandbar habitat snag distribution; however, the outer banks of river bends exhibited a more balanced vertical distribution of snags than inner banks of river bends or along the banks of river straightaways. Limitations and proposed modifications to the digital imaging methods are discussed, and recommendations are provided in support of increased water flows for ecological sustainability in the Apalachicola River.

▼ Clay Settling Areas (CSAs) occupy large areas in the post-phosphate mining landscape. Portions of these structures develop depressions, as a result of clay settling and post-mining topography, which tend to act as wetlands by holding water and supporting wetland vegetation. These areas exist in a state of arrested ecological succession, commonly dominated by pioneer and invasive species, as most CSAs are spatially disconnected from naturally occurring wetland communities and consequently lack desirable seed sources. As a result, the introduction of wetland herbaceous and woody species on CSAs may increase overall species richness and result in more fully functional wetland communities. Five wetland areas were designed and implemented with a high diversity of herbaceous and tree species on sites exhibiting a range of hydrologic conditions and existing vegetation. Open water depressional features with no canopy were planted at two sites with herbaceous marsh species and a periphery of trees and shrubs. Twenty-three species of wetland tree seedlings were planted under an existing Salix caroliniana-dominated canopy at three sites. A variety of herbaceous species were observed that were suited for wetland revegetation in open depressional marsh features including Scirpus californicus (giant bulrush), Saggitaria lancifolia (bulltongue arrowhead), and Pontederia cordata (pickerelweed) in deeper areas, Eleocharis cellulosa (club-rush) and Cladium jamaicense (saw-grass) in moderately flooded areas, and Spartina bakeri (sand cordgrass), Juncus effuses (common rush), Peltandra virgnica (green arrow arum), and Cladium jamaicense in shallow and transitional wetland areas. Canopy and subcanopy tree species from a variety of wetland ecosystems common to southwest Florida, including bay swamps, floodplain forests (river swamps), cypress domes, hydric hammocks, and mixed hardwood swamps, were able to successfully establish at planting sites, however for most species, seedling survival was greater under a stable canopy than in full sunlight likely due to less competition from volunteer species and a more suitable microclimate. Lack of success by several planted species should not indicate a general inappropriateness of these species for CSA wetlands due to the severe drought conditions experienced over the period of record. Several herbaceous and tree species exhibited trends in growth and survival based on available moisture along the sites? hydrologic gradient, most apparent at sites with a steep slope and greater sand content in soils. Composition and structure of volunteer and recruited vegetation was strongly influenced by hydrologic conditions and shading, most notably at marsh planting sites where minimal inundation and lack of canopy shade allowed the encroachment of upland and transitional wetland species including Imperata cylindrica (cogon grass), Ludwigia peruviana (Peruvian primrose willow), Eupatorium capillifolium (dog fennel), and Baccharis halimifolia (eastern baccharis).

▼ Constructed wetlands are increasingly being used worldwide to facilitate nutrient removal, in particular, phosphorus in Florida, from agricultural runoff or conventional wastewater treatment plant effluents. Two-dimensional (2-D) flow dynamics, solute transport, and phosphorus dynamics models are developed to simulate spatio-temporal variations of flow and/or phosphorus dynamics in constructed wetlands. The MIKE 21 hydrodynamics (HD), advection-dispersion (AD), and ECO Lab models were adopted as the basic framework with modifications and enhancement of phosphorus kinetic pathways to incorporate ecosystem dynamics among water column, floc and upper soil layers, and vegetative communities including emergent aquatic vegetation (EAV), submerged aquatic vegetation (SAV), and periphyton. The models were calibrated and validated for two constructed wetland systems in Florida: the Orlando Easterly Wetland (OEW) Cell 7 and the Stormwater Treatment Area (STA) 5 northern flow-way. The spatio-temporal water level fluctuations, tracer (bromide/chloride), and phosphorus concentration profiles were reasonably simulated through linkages between the HD and the AD or ECO Lab model, and key model parameters were estimated. The OEW modeling study is focused on impacts of topographic and vegetative heterogeneity on short-circuiting flow through sensitivity analysis deduced during model calibration on a bromide breakthrough curve. The short-term simulation results show that relic ditches or other ditch-shaped landforms and the associated sparse vegetation along the main flow direction intensify the short-circuiting pattern, considerably reducing hydraulic efficiency. In the northern flow-way of STA 5, the HD model calibration for six long-term monitoring sites accurately represented observed annual variations in hydroperiod. On average, the root-mean-square error (RMSE) for predicting daily water level was less than 0.10 m. Manning?s roughness coefficients for dense EAV and SAV areas, which were estimated as a function of vegetation type and density, ranged from 0.67 to 1.0 s/m1/3 and 0.12 to 0.15 s/m1/3, respectively. The AD model calibration for four long-term monitoring sites agreed very well with the measured annual variations in chloride concentration with the average RMSE of 13.48 mg/L. Longitudinal dispersivity was estimated to be 2 m and was over an order of magnitude higher than the transverse one. Results of conservative phosphorus transport simulation confirm the findings of recent STA studies that the EAV systems are less efficient for phosphorus retention compared to the SAV systems and current STA system is not sufficient for reducing dissolved organic phosphorus (DOP) concentration to very low levels. Linked with the HD model, the calibrated ECO Lab phosphorus dynamics model better simulated observed annual variations in soluble reactive phosphorus (SRP) and DOP level than particulate phosphorus (PP) level, which is primarily due to uncertainty of model parameters on spatio-temporal variations of mass transfer mechanisms… Advisors/Committee Members: Wise, William R.

▼ The interaction between irrigation and stream systems near Palo Verde National Park, Costa Rica provided an opportunity to investigate critical concepts in stream ecology: ecohydrology, riparian patch ecology, and the river continuum concept, while addressing water management issues. This study integrated these components by exploring: 1) Effects of canals on stream community structure and function, and 2) Whether canals and streams have similar structure and function at the landscape level. The ecohydrology investigation compared intermittent and perennial tropical dry forest streams. It provided details on their aquatic communities and demonstrated the strong influence of streamflow on the colonization, development, and succession of aquatic biota. Furthermore, this investigation increased knowledge of tropical dry forest stream ecosystems, which have been studied very little and exist within a threatened forest ecosystem. It also revealed that impacts of irrigation canals on tropical dry forest streams included increased habitat during the dry season, habitat fragmentation, channel scouring, and water quality changes. The riparian patch investigation compared four distinct stream environments resulting from canal management at a site where an irrigation canal crossing is maintained without riparian vegetation and canal water is directly discharged into the stream. Some differences in physical-chemical characteristics and the biotic community were found between the deforested stretch and the adjacent upstream and downstream forested stretches, but that small-scale riparian deforestation ( < 35 m) may not have severe detrimental effects on the stream community and may actually provide a greater diversity of habitats and resources that enhances biotic richness. In addition, perennial discharge from the canal into the stream may provide refugia in the dry season and a source of colonizers for the seasonal stream reach. The canal continuum investigation analyzed the size classes of irrigation canals that diminish in size over their longitudinal gradient both to determine their structure and function and to examine whether canals follow predictions of the River Continuum Concept (RCC), but in reverse order. As a whole, the canals did support an aquatic community whose structure and function did change over their longitudinal gradient, and the canals did follow some RCC predictions.

▼ High-resolution projections of temperature and precipitation changes in Florida during January and July through the year 2100 were produced by GIS-based geostatistical downscaling of general circulation model outputs provided by the Community Climate System Model 3.0 (CCSM) for IPCC benchmark scenarios B1, A1B and A2. Calibration methods designed to assess and correct for CCSM biases were evaluated and implemented. Results indicate mean statewide temperature anomalies ranging from +1.32degreeC to +2.64degreeC during January by the end of the century. All scenarios reveal a weakening of the latitudinal climatic gradient during winter. The northwestern panhandle is projected to experience the greatest warming, with anomalies decreasing towards the southeast. July anomalies range from +1.22degreeC to +3.38degreeC with little regional differentiation except for scenario A2, which projects Florida to become more isothermal than is presently the case. Only scenario B1 projects greater warming in January than July. Mean statewide precipitation anomalies for January are near-zero for all scenarios, whereas during July, anomalies range from -21 mm to -42 mm. Panhandle precipitation is expected to remain similar to present conditions or slightly wetter. South Florida is projected to experience highly significant drying, with some areas projected to receive as little as 23.6% of current rainfall under scenario A2. Projected patterns of change strongly suggest increasing temperature stress for temperate and warm-temperate taxa near the southern margin of their distribution, while barriers to northward expansion of subtropical and tropical taxa are reduced due to the decreasing slope of the latitudinal winter temperature gradient. As they expand the northern margin of their range, warm-adapted species are likely to successfully compete with and exploit resources made available by failing temperate and warm-temperate communities. Subtropical and tropical species in south Florida will experience increasing water stress due to sharply reduced summer precipitation, favoring drought-tolerant species in novel ecological communities without present analogs.

▼ Riparian zones act as filters for nutrients and sediment, and provide food and habitat for terrestrial and aquatic organisms. Preserving riparian structure in headwater streams is critical to protecting local and downstream aquatic biota. Forestry practices along streams are capable of degrading riparian zone function, leading to increased sediment and nutrient inputs, limiting organic matter availability, and altering light and temperature levels in streams. The effects of forestry practices on aquatic invertebrate communities were evaluated in coastal plain streams by experimentally manipulating two harvest regimes in headwater streams based on Georgia?s best management practices. Though the primary goal of the study was to relate anthropogenic disturbances to water quality, a drought occurring prior to the study created degraded streams with low invertebrate abundance and diversity. The drought resulted in streambeds with large amounts of stored organic matter and nutrients, that became available with re-wetting. A core set of species appeared immediately following drought in the streams, reflecting a shared species pool. These species shared resilient traits, including short life cycles and resistance to desiccation, which allowed for rapid recovery from disturbance. However, temporal shifts in biological traits reflected a more stable hydrologic regime over time. As communities recovered, a shift occurred from individuals that were small, sclerotized, and abundant in drift, to those that were larger, soft-bodied, and rare in drift, indicating that the habitat was more favorable. Thus, such shifts in trait structure and the role of natural disturbances need to be accounted for when bioassessment programs are implemented. To evaluate the effects of logging on streams, macroinvertebrates were sampled in reference and harvest streams before and after an experimental harvest. In response to harvest, communities shifted from detritivores to herbivores, following a shift in the food source from organic matter to algae and macrophytes. This change was most apparent in the thinned SMZ, where chlorophyll a was 50-100% higher than in the intact SMZ and reference streams. In general, changes in community structure were most apparent the first year following the harvest and began to follow a trajectory of recovery over the next four years. Interestingly, multimetric indices of water quality based on macroinvertebrates suggested more favorable conditions in the most disturbed treatment (Thinned SMZ). This relates to increases in food quality, due to an increase in algae and macrophytes, and a decrease in C:N ratios in terrestrially derived leaves. However, invertebrates in the thinned SMZ were represented by species preferring to live in sand, highlighting the increased isolation of patches apparent in these reaches. Observational and experimental field work was used to determine the effects of altered habitat amount and type on macroinvertebrate colonization and movement patterns. Macrophyte patches were more complex,… Advisors/Committee Members: Crisman, Thomas L. (committee chair), Holt, Robert D. (committee member), Wise, William R. (committee member), Bolker, Benjamin M.
