These raster data represent the results of a case study in Arizona on how vertebrate richness metrics can be used with existing state and federal guidance in wind and solar energy facility siting. Each of the four geodatabases (see Cross References) contain eight native terrestrial wildlife group models in Arizona: 1) all vertebrates, 2) amphibians, 3) reptiles, 4) birds, 5) mammals, 6) bats, 7) raptors and 8) long-distant migratory birds. An XML workbook is included that lists all terrestrial native vertebrate species in Arizona which cross-walks these species to the name of the National Gap Analysis Project species distribution model.
The data contained in child items of this page were developed to support the Species Status Assessments conducted by the U.S. Fish & Wildlife Service and conservation planning for State, Federal, and non-government researchers, managers, landowners, and other partners for five focal herpetofauna species: gopher tortoise (Gopherus polyphemus), southern hognose snake (Heterodon simus), Florida pine snake (Pituophis melanoleucus mugitus), gopher frog (Lithobates capito), and striped newt (Notophthalmus perstriatus). These data were developed by the USGS Cooperative Fish & Wildlife Research Unit at the University of Georgia in collaboration with other partners. The three child items contain the following data: (1)...

The dataset consists of two csv files one for adult snakes and one for captive-reared juvenile snakes. The data contains start times (when snakes entered the study) and end times (when snakes died or were censored from the study) for survival analysis. The data also contains general information about the individual snakes (id, snout-vent length, treatment group, whether or not they were translocated), sex (juveniles only since adults were all female), surface activity (and data needed to calculate surface activity), and average distance moved between telemetry resighting. The above information was used as covariates in the survival models. These data support the following publication: Nguyen, A.M., Todd, B.D....

Observations (reduced to detected/not detected) of 45 vertebrate species (seven mammals, seven amphibians, and 31 reptiles) across Southern California pitfall sampling projects conducted between 1995 through 2015. Habitat patch locations of every pitfall sampling project presented in a shapefile. Habitat patches were measured based on the size when pitfall sampling began within each. Sampling projects within the same geographic area may have different sized patches based on date of project sampling and if patch erosion occurred. A matrix of whether each species was expected within each habitat patch's species pool based on range maps and published records is also included. These data support the following publication:...

Conversion and fragmentation of wildlife habitat often leads to smaller and isolated populations and can reduce a species’ ability to disperse across the landscape. As a consequence, genetic drift can quickly lower genetic variation and increase vulnerability to extirpation. For species of conservation concern, quantification of population size and connectivity can clarify the influence of genetic drift in local populations and provides important information for conservation management and recovery strategies. Here, we used genome-wide single nucleotide polymorphism (SNP) data and capture-mark-recapture methods to evaluate the population structure, genetic diversity and abundance of seven focal sites of the endangered...
This dataset contains the results from 80 visual encounter surveys at two wetlands in Palmetto Island State Park, Vermillion Parish, Louisiana from August 2015 to April 2019. These surveys mainly targeted snakes but small turtles and anoles were also opportunistically captured. Captured animals were swabbed to determine the prevalence of Ophidiomyces ophiodiicola, the causative agent of Snake Fungal Disease. Physical measurements were taken on all captured individuals. This dataset also includes environmental data such as temperature, water level, and humidity at the study site.
The size and sex of each of the Burmese pythons swabbed in this study for the SFD-causing (snake fungal disease) Ophidiomyces ophiodiicola pathogen is given along with the real time PCR swab result.

A study comparing reintroduction scenarios for the San Francisco gartersnake (Thamnophis sirtalis tetrataenia), an endangered subspecies native to San Mateo County and Santa Cruz County in northern California. Models for snake survival, growth, fecundity, and reproductive status were used to construct a demographic population model. Data are posterior distributions for demographic parameters from Markov Chain Monte Carlo sampling in hierarchical Bayesian models. These data support the following publication: Rose, J.P., Kim, R., Schoening, E.J., Lien, P.C., and Halstead, B.J., 2023.

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.

Capture-mark-recapture data from San Francisco Gartersnakes at five sites in San Mateo County, California in 2018. These data include capture histories, snout-vent lengths, and sex for individual snakes. R files included with the data fit closed capture-mark-recapture models to estimate the abundance of adult snakes at each site in 2018.
Data are from biological and physical environmental assessments conducted during 2018 in the lower Rouge River, MI. Sites were located upstream, downstream, and within the concrete channel section of the lower Rouge River. Water quality parameters, riparian zone characteristics, reptiles and amphibians, fishes, invertebrates, and river channel characteristics (water depth, flow, velocity) were assessed during 2018 from June-October. Previously established standardized sampling methods were used during all assessments.
These data represent the interaction between two male individuals of California Kingsnakes in Apache Junction, northern Pinal County, Arizona. The interaction was observed, recorded on video, and documented. The dataset is a time series description of the interaction and behaviors of two male California Kingsnakes (Lampropeltis californiae; the two individuals are labeled "B" and "D" for purposes of description) which was used to describe aspects of the interaction in the accompanying publication. Second-by second breakdown of the video sequence provided the "time-stamped" descriptions contained in the data table. These data support the journal article "Lampropeltis californiae (California Kingsnake) behavior, male...
These datasets include occurrence points and trait data for freshwater fishes, amphibians, and reptiles native to Oregon State. Occurrence data were extracted from the VertNet database and include points within Oregon, Washington, and Idaho, as well as points found within ecoregions that overlap with Oregon state (U.S. EPA Level III EcoRegions). Occurrence points include records from years 1930-2002, and only records with associated museum voucher specimens were included. Database was updated to include one record per species, per year, at a given location. Records were evaluated by taxonomic experts for each species, and suspicious records were either verified or excluded. Trait data were gathered from published...
These data were acquired from 7 study sites distributed across the range of Gopherus agassizii. Data were collected from 1997 to 2002 as part of three separate studies, although data were not collected at all sites in each year. Radio-transmitters were attached to the carapace of 151 females and VHF radio-telemetry was used to relocate animals to assess reproductive status. Egg production was determined from X-radiographs taken weekly/biweekly intervals (depending on the study) using a portable X-ray machine between April and July or August of each year. In addition, the mean carapace length (MCL) of each tortoise was measured at each time of capture or recapture using calipers (mm). A nesting event was recorded...

These data were compiled to evaluate reproductive output of Agassiz's desert tortoises (Gopherus agassizzi) in relation to environmental and individual-level variables. We collected data from four study sites in the Sonoran Desert of California, including two separate populations within Joshua Tree National Park, one population located on the northern versant of the Orocopia Mountains, and one population located at the extreme western end of the Coachella Valley. These data represent eight reproductive seasons that spanned over 20 years (1997-2000, 2015-2018). These data were compiled and added to a larger database with additional records collected by other scientists from eight other study sites in order to detect...
The Mogollon Narrowheaded gartersnake (Thamnophis rufipunctatus) and the Northern Mexican gartersnake (Thamnophis eques megalops) are both listed as Threatened under the Federal Endangered Species Act. Both species have a strong association with aquatic habitats, and these habitats have been highly altered from impoundments, land-use changes, and the introduction and spread of non-native aquatic species, which have contributed to declines in Arizona and New Mexico over the last 30-40 years. We characterized 125 microsatellite loci per species to generate genetic toolsets for use in long term genetic monitoring of populations. We evaluated microsatellite loci for missing data and several variability thresholds, which...
