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...
The Gopher Tortoise Focal Area represents an area of interest pertaining to the gopher tortoise under the U.S. Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS) Working Lands for Wildlife (WLFW) Wildlife Habitat Incentive Program (WHIP).Working Lands for Wildlife is a partnership between NRCS and the U.S. Fish and Wildlife Service (FWS) to use agency technical expertise and financial assistance from the Wildlife Habitat Incentive Program to combat the decline of seven specific wildlife species whose decline can be reversed and will benefit other species with similar habitat needs. The WLFW project will target species whose decline can be reversed and will benefit other species with...
These data depict reptile species richness within the range of the Greater Sage-grouse. Species boundaries were defined as the total extent of a species geographic limits. This raster largely used species range data from "U.S. Geological Survey - Gap Analysis Project Species Range Maps CONUS_2001", however in order for a more complete picture of species richness, additional sources were used for species missing from the Gap Analysis program.
Habitat use of breeding green turtles Chelonia mydas tagged in Dry Tortugas National Park: Making use of local and regional MPAs
Use of existing marine protected areas (MPAs) by far-ranging marine turtles can be determined using satellite telemetry. Because of a lack of information on MPA use by marine turtles in the Gulf of Mexico, we used satellite transmitters in 2010 and 2011 to track movements of 11 adult female breeding green turtles (Chelonia mydas) tagged in Dry Tortugas National Park (DRTO), in the Gulf of Mexico, south Florida, USA. Throughout the study period, turtles emerged every 9–18 days to nest. During the intervals between nesting episodes (i.e., inter-nesting periods), the turtles consistently used a common core-area within the DRTO boundary, determined using individual 50% kernel-density estimates (KDEs). We mapped the...
Time to First Detection of Northwestern Pond Turtles and Red-eared Sliders by Bait Type in the Sacramento Valley, California, 2018
These data provide the time to first detection in days of Northwestern Pond Turtles (Actinemys marmorata) and Red-eared Sliders (Trachemys scripta elegans) by trapping location and bait type in the Sacramento Valley, California, in 2018. Bait types evaluated include sardines and dry cat food. Only location, species, and bait type combinations that resulted in captures are included. These data are supported by the following publication: Fulton, A.M., Rose, J.P., and Halstead, B.J., 2022. Are sardines or dry cat food more effective as bait for capturing Northwestern Pond Turtles (Actinemys marmorata) and Red-eared Sliders (Trachemys scripta elegans)?

Units dividing the Columbia Basin in to BC Hydro reservoir-based watersheds
Number of turtle and crocodilian species, by freshwater ecoregion. We generated the map of freshwater turtle and crocodilian species richness—the number of species present in each ecoregion—from species distribution maps, primarily drawing on the sources listed below. Distribution maps for 260 freshwater turtle species were provided by Buhlmann et al. (2007). The original distribution maps represented coarse ranges of where species were thought to be present in the wild; however, they were not exact ranges. Buhlmann et al. compiled data from museum and literature records. They correlated verified locality points with GIS-defined hydrologic unit codes (HUCs) and subsequently created “projected” distribution maps...
These data are compiled from published studies of various subspecies of the slider turtle (Trachemys scripta) from throughout the native range of the species in the United States. Data include sample sizes of adult male and female turtles as well as various estimates of their body size as noted in the Comments column.
