The dataset contains 3 components: (1) acceleration data logger (ADL) data, (2) GPS location data, and (3) body temperature data. We have ADL data from pythons in captivity (N = 2) and in free-ranging snakes (N=4). We have GPS data for 3 out of 4 free-ranging snakes. We have body temperature data for all 4 free-ranging snakes.

Temperature is an important factor in understanding biogeography and species composition. In south Florida, non-native fishes’ tolerance to low temperatures is a critical factor in delineating their geographic spread. We provide a literature review summarizing the current state of knowledge of low-temperature tolerances for all seventeen non-native fishes that have been found in Everglades National Park.

Bullseye snakehead, Channa marulius, was first detected in 2000 in the southern Florida town of Tamarac and has been expanding its geographic range. Environmental DNA (eDNA) analysis is a newly-developed technique used to non-invasively detect cryptic or low-density species, or those that are logistically difficult to study. Genetic material shed into the environment through tissue and body fluids is concentrated from water samples and analyzed for the presence of target species eDNA. To help delineate bullseye snakehead’s geographic range, we developed and validated a species-specific eDNA assay for both quantitative and droplet digital PCR (ddPCR). We then used ddPCR to assess 16 locations in southeast Florida...

Ecological models facilitate evaluation and assessment of alternative plans for restoring the Greater Everglades ecosystem. Modeling outputs were used in evaluations of alternative water control plans to be performed by the Combined Operational Plan (COP). The models used were: (1) Cape Sable Seaside Sparrow Marl Prairie Indicator in conjunction with (2) Cape Sable Seaside Sparrow Helper, (3) Florida apple snail (native) population model (EverSnail), (4) Wader Distribution Evaluation Modeling (WADEM), (5) Small-sized freshwater fish density, and (6) Alligator production probability (i.e., habitat suitability index (HSI)). These ecological models are used to examine potential impacts on the above listed flora and...

Restoration of the Florida Everglades, a substantial wetland ecosystem within the United States, is one of the largest ongoing restoration projects in the world. Decision-makers and managers within the Everglades ecosystem rely on ecological models forecasting indicator wildlife response to changes in the management of water flows within the system. One such indicator of ecosystem health, the presence of wading bird communities on the landscape, is currently assessed using three species distribution models that assume perfect detection and report output on different scales that are challenging to compare against one another. We sought to use current advancements in species distribution modeling to improve models...
Old World Climbing Fern (Lygodium microphyllum (Cav.) R. Br.) is an invasive plant species threatening South Florida ecosystems. In 1989 L. microphyllum was observed in the Arthur R. Marshall Loxahatchee National Wildlife Refuge. L. microphyllum has attributes that allow it to thrive in South Florida. It produces a huge number of small spores that are easily suspended by wind and dispersed, have a high germination rate, and gametophytes have a high rate of sporophyte production. Aerial dispersal allows it to spread to suitable germination sites and its ability to self-fertilize at such high rates promotes successful colonization. The intense, abundant spore production also assists in saturating most suitable colonization...
Water quality is a key aspect of the Everglades Restoration Project, the largest water reclamation and ecosystem management project proposed in the United States. Movement of nutrients and contaminants to and from Everglades peat porewater could have important consequences for Everglades water quality and ecosystem restoration activities. In a study of Everglades porewater, we observed complex, seasonally variable peat porewater chloride concentration profiles at several locations. Analyses and interpretation of these changing peat porewater chloride concentration profiles identifies processes controlling conservative solute movement at the peat–surface water interface, that is, solutes whose transport is minimally...
Ecological models facilitate evaluation and assessment of alternative approaches to restore the Greater Everglades ecosystem. However, the provision of useful and accessible models is a challenge because there is often a disconnect between model output and its use by decision makers. Joint Ecosystem Modeling (JEM) meets this challenge by providing ecological model output tailored to management decisions. JEM is a partnership among Federal and state agencies, universities, and other organizations. Ecological models (i.e., ecological planning tools) were used by the multi-agency REstoration, COordination and VERification (RECOVER) science team during the Central Everglades Planning Project (CEPP) and Interim Goals...

This data release provides data for filter-passing total mercury, filter-passing methylmercury, particulate total mercury, particulate methylmercury, and dissolved organic carbon concentrations calculated for USGS station 254543080405401: Tamiami Canal at S-12D Near Miami, FL. Five site-specific regression models were developed using continuously measured temperature, turbidity, specific conductance and or fluorescence of chromophoric dissolved organic matter and concomitant discretely collected dissolved organic carbon samples to calculate continuous concentrations of mercury and carbon.
These data were collected from Burmese pythons removed from the Florida everglades as part of invasive-species management. After euthanasia, we sexed (male or female) and measured the snout-vent length (SVL; cm) and total body mass (g) for each python. We also measured total fat mass (g) by removing all visible fat bodies from the coelomic cavity and weighing this mass. For a subset of specimens, we recorded whether the pythons were put on ice after euthanasia and measured within 24 hours ('fresh') or whether the pythons were frozen after euthanasia, thawed, and then measured ('frozen'). These data were used to validate several body condition indices in Burmese pythons.

Environmental DNA (eDNA) water samples were collected at 15 tree islands containing wading bird breeding colonies (order Pelecaniformes) and 15 empty control islands in the central Everglades of Florida in spring of 2017 (April through June) and analyzed for the presence of eDNA from invasive Burmese pythons (Python bivittatus). The Burmese python is now established as a breeding population throughout south Florida, USA. Pythons can consume large quantities of prey and may be a particular threat to wading bird breeding colonies in the Everglades. To quantify python occupancy rates at tree islands where wading birds breed, we utilized environmental DNA (eDNA) analysis—a genetic tool which detects shed DNA in water...

We used Sherman live traps to capture and mark rodents in the Picayune Strand State Forest between October 2014 and April 2016 (IACUC permit USGS/SESC 2014-12). We selected areas to trap small mammals within the major vegetative types within Picayune Strand State Forest: cypress, pine, hardwood hammock, and wet prairie. We trapped in paired “restored” and “unrestored” areas of each habitat type. Drainage canals in PSSF have been recorded to reduce the water table up from 1.6 – 4.8 km away (Chuirazzi and Duever 2008). Areas considered “restored” were within 1.4 km of Prairie Canal , which was plugged in 2007. Areas considered “unrestored” were at least 8.5 km from the easterly Prairie Canal, in areas that are heavily...
