Burmese python acceleration and location data, Everglades National Park, 2010 – 2012 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.

Greater Everglades Burmese python stable isotope data, 2003-2012, and standard ellipse area literature review, 2018 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...

Stable isotope data and terrain variables for isoscape modeling around two submarine canyons in the western Atlantic sampled in 2012-2013 Terrain variables extracted from bathymetry were used in combination with stable isotope datasets to construct geospatially-explicit isoscapes that predicted variation in carbon and nitrogen isotopes across the canyon-slope seascape, providing insights into the distribution and flow of energy resources, relevant to understanding whole community function.

Green turtle (Chelonia mydas) stable isotope signatures from Dry Tortugas National Park, Florida, sampled 2008-2015 Stable carbon and nitrogen isotope data from green turtles sampled at Dry Tortugas National Park, FL. Dataset includes: date collected, length, tissue type, percent of isotopes, calculated values of isotopes.

Stable isotopic insights into Bathymodiolus childressi at two seeps in the U.S. Atlantic margin Chemosynthetic environments support distinct benthic communities capable of utilizing reduced chemical compounds for nutrition. Hundreds of methane seeps have been documented along the U.S. Atlantic margin (USAM), and detailed investigations at a few seeps have revealed distinct environments containing mussels, microbial mats, authigenic carbonates, and soft sediments. The dominant mussel Bathymodiolus childressi contains methanotrophic endosymbionts but is also capable of filter feeding. We used SIA (δ13C, δ 5N, and δ34S) and an isotope mixing model (MixSIAR) to estimate resource contribution to B. childressi and characterize food webs at two seep sites (Baltimore Seep: 400 m and Norfolk Seep: 1500 m depths) along...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
