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.

Burmese pythons are an invasive species in the Greater Everglades Ecosystem. Burmese pythons captured in the ecosystem are euthanized, and in an effort to learn about this invasive species, all euthanized pythons are necropsied, during which time samples are collected. We analyzed the stable isotope ratios of carbon and nitrogen in muscle samples from 423 Burmese pythons euthanized and necropsied between 2003-05-01 and 2012-09-02, and after processing and QA/QC, we were left with isotope ratios for 410 samples, which we reported here. We used these data to estimate the size of the isotopic niche of the Burmese python, commonly measured using standard ellipse areas, or SEAs. To put these SEAs in context, we conducted...

This dataset contains tracking durations for several species of sea turtles tagged with satellite tags between 2008 and 2019. It contains information on species, turtle size, capture methods, tag type, how many days each tag transmitted, whether or not the tag was still attached upon recapture, fouling 'status' of the tag, and foraging region. This dataset thus allows estimation of tracking durations for four species of marine turtles tagged in different study sites in the Gulf of Mexico and Caribbean.
This dataset contains the capture histories for juvenile green (Chelonia mydas) and hawksbill (Eretmochelys imbricata) sea turtles tagged with an acoustic telemetry tag between 2012 and 2017. It contains information on how many days had passed since the tag was attached and whether or not the tag was still attached upon recapture. This dataset thus allows estimation of acoustic tag retention rates for these two species of sea turtle in our study site at Buck Island Reef National Monument (BIRNM), St. Croix, U.S. Virgin Islands (USVI).
This dataset contains all input parameters required to perform integrated step selection analysis (iSSA) to quantify marine turtle habitat selection relative to marine protected areas throughout coastal Florida and the Gulf of Mexico. The iSSA is a flexible approach to compare the environmental attributes of observed steps (the linear segment connecting two consecutive observed positions of an animal) against a group of alternative steps taken from the same starting location. Information contained in the dataset includes original PIT (passively induced transponder, a unique identifier for each turtle), step ID, step length and log of the step length, turning angle and cosine of turning angle, start and end date...

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...

Environmental DNA (eDNA) detection of invasive species can be used to delimit occupied ranges and estimate probabilities to inform management decisions. Environmental DNA is shed into the environment through skin cells and bodily fluids and can be detected in water samples collected from lakes, rivers, and swamps. In south Florida, invasive Burmese pythons occupy much of the Greater Everglades in mostly inaccessible habitat and are credited with causing severe declines of native species’ populations. Detection of Burmese pythons by traditional methods, such as trapping and visual searching, have been largely ineffective, making eDNA a superior method for differentiating invaded habitat. We adapted a quantitative...
