El Niño Southern Oscillation (Enso) Enhances Co2 Exchange Rates In Freshwater Marsh Ecosystems In The Florida Everglades, Sparkle L. Malone, Christina L. Staudhammer, Steve F. Oberbauer, Paulo Olivas, Michael G. Ryan, Jessice L. Schedlbauer, Henry W. Loescher, Gregory Starr

This research examines the relationships between El Niño Southern Oscillation (ENSO), water level, precipitation patterns and carbon dioxide (CO2) exchange rates in the freshwater wetland ecosystems of the Florida Everglades. Data was obtained over a 5-year study period (2009–2013) from two freshwater marsh sites located in Everglades National Park that differ in hydrology. At the short-hydroperiod site (Taylor Slough; TS) and the long-hydroperiod site (Shark River Slough; SRS) fluctuations in precipitation patterns occurred with changes in ENSO phase, suggesting that extreme ENSO phases alter Everglades hydrology which is known to have a substantial influence on ecosystem carbon dynamics. Variations in …
Applying Downscaled Global Climate Model Data To A Hydrodynamic Surface-Water And Groundwater Model, Eric Swain, Lydia Stefanova, Thomas Smith
Applying Downscaled Global Climate Model Data To A Hydrodynamic Surface-Water And Groundwater Model, Eric Swain, Lydia Stefanova, Thomas Smith
FCE LTER Journal Articles
Precipitation data from Global Climate Models have been downscaled to smaller regions. Adapting this downscaled precipitation data to a coupled hydrodynamic surface-water/groundwater model of southern Florida allows an examination of future conditions and their effect on groundwater levels, inundation patterns, surface-water stage and flows, and salinity. The downscaled rainfall data include the 1996-2001 time series from the European Center for MediumRange Weather Forecasting ERA-40 simulation and both the 1996-1999 and 2038-2057 time series from two global climate models: the Community Climate System Model (CCSM) and the Geophysical Fluid Dynamic Laboratory (GFDL). Synthesized surface-water inflow datasets were developed for the 2038-2057 …
Genetic Evidence For Multiple Sources Of The Non-Native Fish Cichlasoma Urophthalmus (Günther; Mayan Cichlids) In Southern Florida, Elizabeth Harrison, Joel C. Trexler, Timothy M. Collins, Ella Vazquez-Domínguez, Ulises Razo-Mendivil, Wilfredo A. Maramoros, Christian Barrientos

The number and diversity of source populations may influence the genetic diversity of newly introduced populations and affect the likelihood of their establishment and spread. We used the cytochrome b mitochondrial gene and nuclear microsatellite loci to identify the sources of a successful invader in southern Florida, USA, Cichlasoma urophthalmus (Mayan cichlid). Our cytochrome b data supported an introduction from Guatemala, while our microsatellite data suggested movement of Mayan Cichlids from the upper Yucatán Peninsula to Guatemala and introductions from Guatemala and Belize to Florida. The mismatch between mitochondrial and nuclear genomes suggests admixture of a female lineage from Guatemala, …
The Relationship Between Water Level, Prey Availability And Reproductive Success In Roseate Spoonbills Foraging In A Seasonally-Flooded Wetland While Nesting In Florida Bay, Jerome J. Lorenz
FCE LTER Journal Articles
The coastal wetlands of northeastern Florida Bay are seasonally-inundated dwarf mangrove habitat and serve as a primary foraging ground for wading birds nesting in Florida Bay. A common paradigm in pulse-inundated wetlands is that prey base fishes increase in abundance while the wetland is flooded and then become highly concentrated in deeper water refuges as water levels recede, becoming highly available to wading birds whose nesting success depends on these concentrations. Although widely accepted, the relationship between water levels, prey availability and nesting success has rarely been quantified. I examine this paradigm using Roseate Spoonbills that nest on the islands …
Effect Of Water Management On Interannual Variation In Bulk Soil Properties From The Eastern Coastal Everglades, R. M. Chambers, R. L. Hatch, T. M. Russell
Effect Of Water Management On Interannual Variation In Bulk Soil Properties From The Eastern Coastal Everglades, R. M. Chambers, R. L. Hatch, T. M. Russell
FCE LTER Journal Articles
We examined interannual variation in soil properties from wetlands occurring in adjacent drainage basins from the southeastern Everglades. Triplicate 10-cm soil cores were collected, homogenized, and analyzed during the wet season 2006–2010 from five freshwater sawgrass wetland marshes and three estuarine mangrove forests. Soil bulk density from the Taylor Slough basin ranged from 0.15 gm-cm−3 to 0.5 gm-cm−3, was higher than from the Panhandle basin every year, and generally increased throughout the study period. Organic matter as a percent loss on ignition ranged from 7 % to 12 % from freshwater marshes and from 13 % to …
A Review Of The Effects Of Altered Hydrology And Salinity On Vertebrate Fauna And Their Habitats In Northeastern Florida Bay, Jerome J. Lorenz
A Review Of The Effects Of Altered Hydrology And Salinity On Vertebrate Fauna And Their Habitats In Northeastern Florida Bay, Jerome J. Lorenz
FCE LTER Journal Articles
Estuarine productivity is highly dependent on the freshwater sources of the estuary. In Florida Bay, Taylor Slough was historically the main source of fresh water. Beginning in about 1960, and culminating with the completion of the South Dade Conveyance System in 1984, water management practice began to change the quantity and distribution of flow from Taylor Slough into Northeastern Florida Bay. These practices altered salinity and hydrologic parameters that had measurable negative impacts on vertebrate fauna and their habitats. Here, I review those impacts from published and unpublished literature and anecdotal observations. Almost all vertebrates covered in this review have …

There is observational evidence that global sea level is rising and there is concern that the rate of rise will increase, significantly threatening coastal communities. However, considerable debate remains as to whether the rate of sea level rise is currently increasing and, if so, by how much. Here we provide new insights into sea level accelerations by applying the main methods that have been used previously to search for accelerations in historical data, to identify the timings (with uncertainties) at which accelerations might first be recognized in a statistically significant manner (if not apparent already) in sea level records that …
Seasonal Evapotranspiration Patterns In Mangrove Forests, Jordan G. Barr, Marcia S. Delonge, Jose D. Fuentes
Seasonal Evapotranspiration Patterns In Mangrove Forests, Jordan G. Barr, Marcia S. Delonge, Jose D. Fuentes
FCE LTER Journal Articles
Diurnal and seasonal controls on water vapor fluxes were investigated in a subtropical mangrove forest in Everglades National Park, Florida. Energy partitioning between sensible and latent heat fluxes was highly variable during the 2004–2005 study period. During the dry season, the mangrove forest behaved akin to a semiarid ecosystem as most of the available energy was partitioned into sensible heat, which gave Bowen ratio values exceeding 1.0 and minimum latent heat fluxes of 5 MJ d1. In contrast, during the wet season the mangrove forest acted as a well-watered, broadleaved deciduous forest, with Bowen ratio values of 0.25 and latent …
