We conducted a radio telemetry study of adult western spadefoots (Spea hammondii) at 2 sites in southern California to characterize their survival, behavior, and movements from breeding through aestivation to inform conservation and management for the species. These data support the following publication: Halstead, B.J., Baumberger, K.L., Backlin, A.R., Kleeman, P.M., Wong, M.N., Gallegos, E.A., Rose, J.P., and Fisher, R.N., 2021. Conservation implications of spatiotemporal variation in the terrestrial ecology of an ephemeral pool-breeding amphibian. The Journal of Wildlife Management.

These data consist of microsatellite genotype scores for all samples of Santa Ana sucker (Catostomus santaanae) used in the study. Scores represent the allele calls for each microsatellite locus (i.e. DNA fragment length containing the microsatellite repeats), with each locus containing two scores representing the two allele copies detected. Included are five tables: Full dataset (includes genotypes from all samples), Santa Clara River samples only (includes genotypes only from samples collected in the Santa Clara River), Convert File format key (explains the data file format), Population identifiers (translates the numerical population identifiers to actual collecting sites), CASA sampling points (one coordinate...

Comma-separated values (.csv) file containing data related to amphibian sampling across the United States between 2016 and 2021. Data files contain mercury concentrations in amphibian and dragonfly tissues, mercury concentrations in sediment, as well as amphibian morphometrics, and habitat and climate characteristics where the samples were collected.

This dataset provides the results of a national survey of the conterminous U.S. for the salamander chytrid fungus Batrachochytrium salamandrivorans (Bsal) conducted by the U.S. Geological Survey Amphibian Research and Monitoring Initiative from May 2014 to August 2017. Sites were sampled by capturing amphibians by hand or by traps or nets that were then swabbed individually using methods that prevent sample contamination. All swabs were then analyzed using a real-time TaqMan PCR for detection of B. salamandrivorans on the extracted DNA. The data consist of locality information and data on the individual sampled, as well as the result of the test for B. salamandrivorans. No cases of B. salamandrivorans were detected...

In February 2017, a population of California red-legged frog Rana draytonii was discovered in the southern foothills of the San Bernardino Mountains of Riverside County, California, near the edge of the species’ historic distribution. A few days after the first sightings of R. draytonii at the Whitewater Preserve, we conducted a visual daytime search for frogs, tadpoles and egg masses followed by a nighttime eye shine search for adult frogs. The captured frog weighed, measured (snout-to-urostyle [SU]), sampled for tissue and georeferenced using a GPS unit. Survey work was authorized by a U.S. Fish and Wildlife Service Recovery Permit and a California Department of Fish and Wildlife Scientific Collecting Permit....
