The Comprehensive Everglades Restoration Plan (CERP) requires the use of ecological indicators to measure the success of restoration efforts. The Everglades amphibian community is ideal because amphibians are present in all habitats and under all hydrologic regimes. During Everglades restoration, hydrologic patterns will change and the response of ecological indicators will determine success. Fourteen amphibian species were detected through visual encounter surveys (VES), vocalization surveys and trapping methods throughout the study and the occurrence information collected in this project database.
The 1995 - 2007 Ecosystem History of South Florida's Estuaries Database contains listings of all sites (modern and core), modern monitoring site survey information (water chemistry, floral and faunal data, bottom type, etc.), and published core data. Three general types of data are contained within this database: 1) Modern Field Data (1995-2007), 2) Master list of location information on all modern sites, and 3) Core data - faunal assemblages and location information. Data are available for modern sites and cores in the general areas of Florida Bay, Biscayne Bay, and the southwest (Florida) coastal mangrove estuaries. Specific sites in the Florida Bay area include Taylor Creek, Bob Allen Key, Russell Bank, Pass...
Airborne electromagnetic (AEM) and magnetic survey data were collected in Big Cypress National Preserve, Florida as part of a larger survey. Data were collected during October 2001. The Big Cypress National Preserve part was the largest of three segments, totaling 2692.2 line-kilometers. Electromagnetic data were acquired with Dighem VRES frequency-domain system. Magnetic data were collected with a Scintrex CS2 cesium-vapor magnetometer. The line spacing was 400 m and several tie lines were flown. The nominal elevation of electromagnetic system was 30 m. This data release includes raw and processed AEM data. This release also includes unprocessed and processed magnetic data that have been drift corrected.

Airborne electromagnetic (AEM) and magnetic survey data were collected near Homestead, Florida as part of a larger survey. Data were collected during October 2001. The Homestead part of the survey consisted of 277.1 line-kilometers. Electromagnetic data were acquired with Dighem VRES frequency-domain system. Magnetic data were collected with a Scintrex CS2 cesium-vapor magnetometer. The line spacing was 400 m and a single tie line was flown in the middle of the survey area. The nominal elevation of the electromagnetic system was 30 m. This data release includes raw and processed AEM data. This release also includes unprocessed and processed magnetic data that have been drift corrected.

Remote sensing based maps of tidal marshes, both of their extents and carbon stocks, have the potential to play a key role in conducting greenhouse gas inventories and implementing climate mitigation policies. Our objective was to generate a single remote sensing model of tidal marsh aboveground biomass and carbon that represents nationally diverse tidal marshes within the conterminous United States (CONUS). To meet this objective we developed the first national-scale dataset of aboveground tidal marsh biomass, species composition, and aboveground plant carbon content (%C) from six CONUS regions: Cape Cod, MA, Chesapeake Bay, MD, Everglades, FL, Mississippi Delta, LA, San Francisco Bay, CA, and Puget Sound, WA....

This dataset contains four comma-delimited files collected to evaluate the utility of GPS biologging tags for studying the spatial ecology of large constricting snakes. The first file contains the dates that five Burmese pythons were deployed for tracking in Everglades National Park, FL. The second file contains the data from each of those five python GPS tags with all of the attempted GPS fixes and their result (success or fail). The third file contains deployment dates and true locations for seven GPS test-platforms deployed in Everglades National Park to assess the effect of habitat on fix success as well as accuracy and precision of the tags in situ. The final file contains the data from each of those seven...

Invasive Burmese pythons (Python bivittatus) have been reproducing in the Florida Everglades since the 1980s. Introduction of the species was either due to unintentional escapes or intentional releases from snakes obtained through the commercial pet trade. Burmese pythons have caused a precipitous decline in small mammal populations in south Florida. To better understand the invasive population, two mitochondrial loci (mtDNA; 1398 bps) were sequenced on 426 snakes and 22 microsatellites were genotyped on 389 snakes. Concatenated cytochrome b and cytochrome oxidase 1 mtDNA sequences produced six haplotypes with a nucleotide and haplotype diversity of π=0.002 and h=0.097, respectively. The dominant haplotype was highly...

This study was initiated to provide baseline data and to determine the utility of stable isotope analysis to evaluate the foraging strategies of an opportunistic reptile predator. Stable isotope ratios of carbon and nitrogen were evaluated from multiple tissues from terrapin populations to determine spatial or temporal variations in resource use within mangrove habitats in Southern Florida. We sampled Diamondback terrapin (Malaclemys terrapin) and potential resources within mainland and island habitats, and evaluated their δ13C and δ15N values. We fit linear regression models to determine the best predictors of isotopic values for both terrapins and their prey, and SIBER analysis to examine terrapin isotopic niche...

The study of Whiting Field Naval Air Station, Milton Florida requires numerical modeling of the groundwater system to determine the fate of contaminants released at the air station in previous decades. The MODFLOW-NWT modeling code (Niswonger and others, 2011) was applied for this purpose with field data defining a number of inputs including aquifer properties and timeseries. Lithologic logs were used to define aquifer material types and estimated hydraulic conductivities were redistributed based on these logs. Net recharge (precipitation minus evapotranspiration) is the primary flow input to the model and stream leakage is the primary flow output. The resulting model simulation has a grid spacing of 100 feet with...
