This dataset contains morphometric information from Burmese pythons collected from an invasive population in southern Florida between 1995-2021. Scientists from the U.S. Geological Survey and the National Park Service curated this dataset as a repository for records of Burmese pythons found on or nearby federal lands in southern Florida, including Everglades National Park, Big Cypress National Preserve, Biscayne National Park, and Crocodile Lake National Wildlife Refuge. As such, numerous entities actively or incidentally involved in python research or management activities contributed specimens and/or data to this dataset, including but not limited to the U.S. Geological Survey, National Park Service, U.S. Fish...
Digestive tract contents were identified to provide an account of Burmese python diet. Diet contents came from 1716 pythons collected by cooperators during 1995-2020 from public and private lands across southern Florida, primarily within the Greater Everglades Ecosystem. Burmese pythons consumed 76 species of fauna across three taxonomic classes (Aves, Mammalia, and Reptilia).

Available active surveillance efforts for Brown Treesnakes on the island of Saipan via nocturnal visual encounter surveys and trapping from 1999-2018 were collected and summarized into 3 csv files (TRAP1999, BTSRRTSaipanTRAP, and BTSRRTSaipanVISUAL). Location and date of non-confirmed reports of snakes 1982-2013 via passive surveillance were compiled into a fourth file (Saipan BTSSightings1980_2020.csv) with their associated credibility score of 1-5 (5 = completely credible) defined by a panel or small group of Brown Treesnake experts. Trapping surveillance efforts used a modified minnow trap as a snake trap. Traps are suspended horizontally from natural vegetation or fences 1-1.5 meter (m) off the ground. Within...
Nocturnal visual encounter surveys for Brown Treesnakes were collected and summarized into 4 plain text files (csv format): CapturesLure, SurveysLure, CapturesScent, and SurveysScent. Capture files contain unique Passive Integrated Transponder (PIT) tag identification and measurements of snakes with dates and locations of capture. Survey files contain the dates of transect sampling and treatment application for each transect (Transect ID). Each project used a different type of attractant, either a live-mouse lures in snake traps or liquid fish fertilizer scented spray. Surveys were conducted in a 5-ha geographically closed population on Guam. Teams of two observers conducted night-time surveys from February 1 to...

Invasive Argentine Black and White Tegu lizards (Salvator merianae) are trapped with chicken eggs when populations are discovered in the United States. Unfortunately, non-targeted mammals are trapped in tegu lizard traps which reduces trap efficacy. We evaluated if non-target mammal captures could be reduced by coating the chicken eggs with a known irritant to mammals (capsaicin) while maintaining a highly desired bait for tegu lizards. The data set quantifies trap disturbance by non-targets species and efficacy of capsaicin coated eggs as bait in live traps set for Argentine Black and White Tegu lizards (Salvatore merianae). The dataset consists of three live trapping experiments to test if 1) trap disturbance...

We provide four datasets: Mark recapture and trapping effort, Grid layout, Chew cards, and Trail camera validation. Mark recapture and trapping effort has one row for every live-trap night, including the unique grid identification code, date of trap check, cumulative rain amount from the 24-hr period before the trap check, unique trap identification, trap status, unique individual rat identification (ID) and associated morphometrics, and rat fate. Grid layout includes the unique grid identification code, unique trap identification, and GPS coordinates of the traps. Chew cards has one row for every chew-card night, including the unique grid identification code, date of chew-card check, unique chew-card identification,...

The presence of serpentoviruses in Burmese pythons (Python bivittatus) and native snakes were collected and compiled to characterize serpentovirus in wild free-ranging pythons and free-ranging native snakes within the invasive range of the pythons in southern Florida. Virus presence was tested in 318 pythons and 219 Native snakes, primarily within the Greater Everglades Ecosystem of south Florida. When available, variables collected from submitted samples used for analysis included sampling date, sampling season (Summer/Fall/Winter/Spring), capture date, sample number (if tested more than once), reverse transcription polymerase chain reaction (rtPCR) result (positive/negative), virus type (categorical), sex (male/female),...
