SERC Research Reports
The work on CERP monitoring item 3.1.3.5 (Marl prairie/slough gradients) is being conducted by Florida International University (Dr Michael Ross, Project Leader), with Everglades National Park (Dr. Craig Smith) providing administrative support and technical consultation. As of January 2006 the funds transferred by ACOE to ENP, and subsequently to FIU, have been entirely expended or encumbered in salaries or wages. The project work for 2005 started rather late in the fiscal year, but ultimately accomplished the Year 1 goals of securing a permit to conduct the research in Everglades National Park, finalizing a detailed scope of work, and sampling marsh …

Assesing The Impact Of Local Incentives On Capital Cost: The Case Of The Indiana Era Program, Esteban G. Dalehite
Assesing The Impact Of Local Incentives On Capital Cost: The Case Of The Indiana Era Program, Esteban G. Dalehite
Department of Public Administration
Public policy makers and administrators around the world recurrently face the question of whether to grant tax privileges to businesses in order to promote investment, jobs, or economic development in general. This article analyzes a very popular form of local incentive, the property tax abatement, and its ability to reduce capital cost. The research question is: By how much do property tax abatements reduce the capital cost of business and homes? Results show that abatements can account for quite a large range of possible percentage reductions in the price of investment for firms. The findings provide public administrators and policy …

Mayoral Leadership And Political - Administrative Relationships In Two Ukrainian Cities, Natalya Kolisnichenko, Valentina Krivtsova, Allan Rosenbaum
Department of Public Administration
The article that follows examines the role of mayoral leadership in two large cities in Ukraine - Kiyv and Odessa. It begins with an examination of the various roles and resources typically found in the office of mayor, as well as a review of some of the unique characteristic of local governance in Ukraine. It then examines the activities of recent mayors in the two cities. It concludes by suggesting a somewhat expanded set of mayoral roles based on the Ukrainian experience.

Entral-Local Administrative And Governance Relationships In Two Ukrainian Cities: Kyiv And Odessa, Natalya Kolisnichenko, Allan Rosenbaum
Department of Public Administration
The institution of local self-government occupies an increasingly important position in Ukrainian society. However, the contemporary system of local self-government in Ukraine is still not consistent with the principles of the European Charter of Local Self-government. In areas such as access to sources of revenue, policy initiation and citizen involvement in local governance, municipal governments in Ukraine frequently fall significantly short of expected European standards. In part, this is due to the lingering influence of the Soviet totalitarian past on the mentality of both the Ukrainian legislators and the representatives of local governments who are working to create democratic principles …

FCE LTER Journal Articles
We examined periphyton along transects in five Everglades marshes and related compositional and functional aspects to phosphorus(P ) gradients caused by enriched inflows. Results were compared to those of a P-addition experiment in a pristine Everglades marsh. While the water total P (TP) concentration was not related to P load in the marshes or experiment the concentration of TP in periphyton was strongly correlated with the distance from the P source. Increased P concentration in periphyton was associated with a loss of biomass,p articularly of the calcifying mat-forming matrix, regardless of the growth form of the periphyton (epiphytic, floating,or epilithic). …

We determined the rate of migration of coastal vegetation zones in response to salt-water encroachment through paleoecological analysis of mollusks in 36 sediment cores taken along transects perpendicular to the coast in a 5.5 km2 band of coastal wetlands in southeast Florida. Five vegetation zones, separated by distinct ecotones, included freshwater swamp forest, freshwater marsh, and dwarf, transitional and fringing mangrove forest. Vegetation composition, soil depth and organic matter content, porewater salinity and the contemporary mollusk community were determined at 226 sites to establish the salinity preferences of the mollusk fauna. Calibration models allowed accurate inference of salinity and vegetation …

Hydrologic Measurements And Implications For Tree Island Formation Within Everglades National Park, Jose Bazante, Gary Jacobi, Helena M. Solo-Gabriele, David Reed, Sherry Mitchell-Bruker, Daniel L. Childers, Lynn Leonard, Michael Ross
FCE LTER Journal Articles
Tree islands in the Shark River Slough of the Everglades National Park (ENP), in the southern state of Florida in the United States, are part of a wetland system of densely vegetated ridges interspersed within relatively open sloughs. Human alteration of this system has had dramatic negative effects on the landscape of the region and restoration efforts will require adjusting the hydrology of the region to assure the preservation of these important ecologic features. The primary objectives of this study were to document the hydrology in the vicinity of tree islands in ENP by measuring velocities in time and space …

We examined the spatial extent of nitrogen (N) and phosphorus (P) limitation of each of the major benthic primary producer groups in Florida Bay (seagrass, epiphytes, macroalgae, and benthic microalgae) and characterized the shifts in primary producer community composition following nutrient enrichment. We established 24 permanent 0.25-m2 study plots at each of six sites across Florida Bay and added N and P to the sediments in a factorial design for 18 mo. Tissue nutrient content of the turtlegrass Thalassia testudinum revealed a spatial pattern in P limitation, from severe limitation in the eastern bay (N:P > 96:1), moderate limitation in …

The Contribution Of Leaching To The Rapid Release Of Nutrients And Carbon In The Early Decay Of Wetland Vegetation, Stephen E. Davis, Dan Childers, Gregory B. Noe
FCE LTER Journal Articles
Our goal was to quantify the coupled process of litter turnover and leaching as a source of nutrients and fixed carbon in oligotrophic, nutrient-limited wetlands. We conducted poisoned and non-poisoned incubations of leaf material from four different perennial wetland plants (Eleocharis spp., Cladium jamaicense, Rhizophora mangle and Spartina alterniflora) collected from different oligotrophic freshwater and estuarine wetland settings. Total phosphorus (TP) release from the P-limited Everglades plant species (Eleocharis spp., C. jamaicense and R. mangle) was much lower than TP release by the salt marsh plant S. alterniflora from N-limited North Inlet (SC). For most species and sampling times, total …
Coastal Groundwater Discharge – An Additional Source Of Phosphorus For The Oligotrophic Wetlands Of The Everglades, René M. Price, Peter K. Swart, James W. Fourqurean
Coastal Groundwater Discharge – An Additional Source Of Phosphorus For The Oligotrophic Wetlands Of The Everglades, René M. Price, Peter K. Swart, James W. Fourqurean
FCE LTER Journal Articles
In this manuscript we define a new term we call coastal groundwater discharge (CGD), which is related to submarine groundwater discharge (SGD), but occurs when seawater intrudes inland to force brackish groundwater to discharge to the coastal wetlands. A hydrologic and geochemical investigation of both the groundwater and surface water in the southern Everglades was conducted to investigate the occurrence of CGD associated with seawater intrusion. During the wet season, the surface water chemistry remained fresh. Enhanced chloride, sodium, and calcium concentrations, indicative of brackish groundwater discharge, were observed in the surface water during the dry season. Brackish groundwaters of …
Assessing The Net Effect Of Anthropogenic Disturbance On Aquatic Communities In Wetlands: Community Structure Relative To Distance From Canals, Jennifer S. Rehage, Joel C. Trexler
Assessing The Net Effect Of Anthropogenic Disturbance On Aquatic Communities In Wetlands: Community Structure Relative To Distance From Canals, Jennifer S. Rehage, Joel C. Trexler
FCE LTER Journal Articles
Anthropogenic alterations of natural hydrology are common in wetlands and often increase water permanence, converting ephemeral habitats into permanent ones. Since aquatic organisms segregate strongly along hydroperiod gradients, added water permanence caused by canals can dramatically change the structure of aquatic communities. We examined the impact of canals on the abundance and structure of wetland communities in South Florida, USA. We sampled fishes and macroinvertebrates from marsh transects originating at canals in the central and southern Everglades. Density of all aquatic organisms sampled increased in the immediate proximity of canals, but was accompanied by few compositional changes based on analysis …

FCE LTER Journal Articles
This article outlines an approach, based on ecosystem services, for assessing the trade-offs inherent in managing humans embedded in ecological systems. Evaluating these trade-offs requires an understanding of the biophysical magnitudes of the changes in ecosystem services that result from human actions, and of the impact of these changes on human welfare. We summarize the state of the art of ecosystem services-based management and the information needs for applying it. Three case studies of Long Term Ecological Research (LTER) sites--coastal, urban, and agricultural-- illustrate the usefulness, information needs, quantification possibilities, and methods for this approach. One example of the application …

Characteristics Of Surface-Water Flows In The Ridge And Slough Landscape Of Everglades National Park: Implications For Particulate Transport, Lynn Leonard, Alexander L. Croft, Dan Childers, Sherry Mitchell-Bruker, Helena Solo-Gabriele, Michael S. Ross
FCE LTER Journal Articles
Over the last one hundred years, compartmentalization and water management activities have reduced water flow to the ridge and slough landscape of the Everglades. As a result, the once corrugated landscape has become topographically and vegetationally uniform. The focus of this study was to quantify variation in surface flow in the ridge and slough landscape and to relate flow conditions to particulate transport and deposition. Over the 2002–2003 and 2003–2004 wet seasons, surface velocities and particulate accumulation were measured in upper Shark River Slough in Everglades National Park. Landscape characteristics such as elevation, plant density and biomass also were examined …
Flux Of Organic Carbon In A Riverine Mangrove Wetland In The Florida Coastal Everglades, Melissa M. Romigh, Stephen E. Davis Iii, Victor H. Rivera-Monroy, Robert R. Twilley
Flux Of Organic Carbon In A Riverine Mangrove Wetland In The Florida Coastal Everglades, Melissa M. Romigh, Stephen E. Davis Iii, Victor H. Rivera-Monroy, Robert R. Twilley
FCE LTER Journal Articles
Short-term (daily) and seasonal variations in concentration and flux of dissolved organic carbon (DOC) were examined over 15 tidal cycles in a riverine mangrove wetland along Shark River, Florida in 2003. Due to the influence of seasonal rainfall and wind patterns on Shark River’s hydrology, samplings were made to include wet, dry and transitional (Norte) seasons. We used a flume extending from a tidal creek to a basin forest to measure vertical (vegetated soil/water column) and horizontal (mangrove forest/tidal creek) flux of DOC. We found significant (p < 0.05) variations in surface water temperature, salinity, conductivity, pH and mean concentration of DOC with season. Water temperature and salinity followed seasonal patterns of air temperature and rainfall, while mean DOC concentration was highest during the dry season (May), followed by the wet (October) and ‘Norte’ (December) seasons. This pattern of DOC concentration may be due to a combination of litter production and inundation pattern of the wetland. In contrast to daily (between tides) variation in DOC flux between the mangrove forest and tidal creek, daily variations of mean water quality were not significant. However, within-tide variation of DOC flux, dissolved oxygen content and salinity was observed. This indicated that the length of inundation and water source (freshwater vs. saltwater) variation across tidal cycles influenced water quality and DOC flux in the water column. Net DOC export was measured in October and December, suggesting the mangrove forest was a source of DOC to the adjacent tidal creek during these periods. Net annual export of DOC from the fringe mangrove to both the tidal creek and basin mangrove forest was 56 g C m−2 year−1. The seasonal pattern in our flux results indicates …

User Interface Design For Semantic Query Expansion In Geodata Repositories, Hartwig H. Hochmair, Zhaohui (Jennifer) Fu
GIS Center
Semantic query expansion is the process of supplementing a user query with additional terms that interpret and extend the user's information needs. This work presents the results of an empirical study that investigates user preferences for different designs of user interfaces that provide semantic query expansion for data search from geo-data repositories. The study assesses further whether it is possible to map qualitative gradations of semantic relatedness between geographic key terms to ranges of numerical similarity values.
