Green turtle genetics in the Gulf of Mexico, 2006-2019
Mitochondrial DNA markers have elucidated patterns of connectivity between green turtle nesting populations (rookeries) and juveniles foraging in neritic nursery habitats. However, missing rookery baseline data and haplotype sharing among populations have often impeded inferences, including ascertaining origins of Gulf of Mexico juveniles. We sequenced the mitochondrial control region and additional informative mitogenomic single nucleotide polymorphisms of juveniles foraging in Port Fourchon, Louisiana (LA, n = 127) and Santa Rosa Island, Florida (SRI, n = 47). We collected additional genetic data for previously characterized neritic aggregations in southern Texas (TX, n = 167), St. Joseph Bay, Florida (SJB, n = 174) and southwestern Florida (SWFL, n = 96). We assessed genetic structure among these sites, incorporating published data from a surface-pelagic (SP) aggregation offshore of Louisiana through Florida and a neritic aggregation from the Big Bend region of Florida (BB). We estimated source contributions to aggregations with new genetic data using a Bayesian many-to-one mixed stock analysis (MSA) approach. This data set contains passive induced transponder (PIT) tag number, sampling site information, capture date, control region (CR) haplotype, mitochondrial short tandem repeat (mtSTR) haplotype, and mitogenetic haplotype for each turtle.

Green sea turtle age, growth, population characteristics (NCEI Accession 0159273)
공공데이터포털
Morphology, sex ratio, body condition, disease status, age structure, and growth patterns were characterized for 448 green sea turtles cold stunned in St. Joseph Bay, Florida during January 2010
Satellite tracking data for post-nesting green turtles from Northwest Florida (2002-2020)
공공데이터포털
This dataset includes processed satellite tracking data collected from green turtles between July 2002 and October 2020 in the Gulf of Mexico. Tracks were located along the west coast of Florida from the Florida Keys to the Gulf Islands National Seashore. Output from the state-space model (SSM) described in Lamont et al. (2023) is included, as are inter-nesting and foraging centroids calculated using kernel density estimates and minimum convex polygons.
Turtle Reproductive Ecology Data, New Mexico, 2012-2013
공공데이터포털
These data represent reproductive ecology characteristics for 4 species of mature female turtles captured at Elephant Butte Reservoir on the Rio Grande River in New Mexico, during two field survey periods in June 2012 and 2013. Data were collected on female reproductive ecology including clutch size, egg size, timing of egg production, and the percentage of reproductive females using X-radiography. The purpose of these data are to add to the deficient information on the reproductive ecology of four turtle species at the Elephant Butte Reservoir on the Rio Grande and Black River in New Mexico. Data contained in this worksheet were analyzed to determine clutch and egg sizes for four native species of turtles (Apalone spinifera, Chrysemys picta, Pseudemys gorzugi, and Trachemys gaigeae gaigeae).
Nesting and non-nesting emergences for four species of imperiled sea turtles derived from acceleration data loggers, 2012-2017
공공데이터포털
These data contain acceleration, pitch, yaw, roll, and ancillary data collected by acceleration data loggers (ADL) attached to four sea turtle species: green (Chelonia mydas) sea turtles, hawksbill (Eretmochelys imbricata) sea turtles, Kemp's ridley (Lepidochelys kempii) sea turtles, and loggerhead (Caretta caretta) sea turtles. A total of 54 nesting events and 76 non-nesting emergence events were identified in the data and validated by satellite tag location data for three of the four species (i.e., Kemp's ridley spatial data not included) and researcher observations.

Tagging date, site, turtle size, and migration and foraging behavioral data for loggerheads (Caretta caretta) nesting at three sites in the Gulf of Mexico from 2011–2019
공공데이터포털
Tagging information, including migration and foraging behavioral data, for female reproductive loggerhead marine turtles (Caretta caretta) that were satellite tagged at nesting beaches at Gulf Shores (Alabama [AL]), Dry Tortugas National Park (DRTO, Florida [FL]), and Everglades National Park (ENP, FL) from 2011–2019. Variables include the tagging date, tagging site, the curved carapace length-notch (CCL-n, cm), the size category (≤ 87 cm CCL-n or > 87 cm CCL-n), and the first and last date of satellite tracking. Migration and foraging behavioral data include the first and last migration dates, the number (no) of days in migration mode, the length (distance) of the migration path distance (km), the mean depth along the migration path (m), the total number of days the turtle exhibited a stopover during migration, the first and last foraging dates, the no of days in foraging mode, the depth at the foraging centroid (m), the distance to shore from the foraging centroid (km), and the total number of days the turtle exhibited a migration foray during foraging.
