This data release includes the data and computer code that we produced to fit two open-robust design removal models developed to simultaneously model population dynamics, temporary emigration, and imperfect detection: a random walk linear trend model (estimable without ancillary information), and a 2-age class integrated population model (IPM) that used prior information for age-structured vital rates and relative juvenile availability. To evaluate the effectiveness of management programs, we applied both models to a multi-year, removal trapping time-series data set of a large invasive lizard (Argentine black and white tegu, Salvator merianae) in three management areas of South Florida collected from 2016-1018....

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...

Argentine Giant Tegu lizard (Salvator merianae) trap effort and count data collected in southern Georgia, USA in 2019. Non-target species associated with the traps were also documented, as were type of bait used and condition of the traps during trap checks.
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...

The mating and reproductive ecology of the invasive Brown Treesnake (Boiga irregularis) were generated by reconstructing a multigenerational genomic pedigree based on 654 single nucleotide polymorphisms for a geographically-closed population established in 2004 on Guam (N=426). The pedigree allowed annual estimates of individual mating and reproductive success to be inferred for snakes in the study population over a 14-year period. These data are then merged with morphological data on each snake.
Manually photo-processed remote camera trap data of Brown Treesnakes on Guam at snake traps with live mouse lures. Records of snakes entering the field of view (FOV) and exiting the FOV by day, time, and trap location. Photos were further processed to retain only detections of snakes up to 1.83 meters from the camera, i.e., only records of snakes that were on or in front of the mouse-lure trap are retained in the data file.

Data fall into three types: 1) individual snake scanning data (PIT tag ID, time stamp, and device) downloaded from readers, 2) individual trait data (sex, size, etc) of tested brown treesnakes, and 3) detailed transcripts of videos of behavioral trial data as snakes interacted with the readers. All data were collected in an experimental arena in Dededo, Guam in August 2021.

These data were collected as part of several studies or efforts to remove brown treesnakes (Boiga irregularis) across three sites located in Guam, USA and one site in Cocos Island (Dano), Guam, USA. The various goals of projects were distinct and these data were applied to a more intensive, cross site comparison on the height snakes were detected during visual surveys as a function of their size or body condition.

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),...
