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 include egg mass counts and adult capture-mark-recapture histories for Foothill Yellow-legged frogs (Rana boylii) at two streams in northern California. Data were collected from the South Fork Eel River and its tributary, Fox Creek, from 1993-2019. Data from Hurdygurdy Creek were collected from 2002-2008.

These data represent trapping effort and captures of deer mice at Point Reyes National Seashore, Marin County, California. Deer mice were captured and marked with ear tags to allow identification of individuals. The location of captures can be used in a spatially explicit capture recapture model to estimate density of mice and how mouse density varies by site and habitat type.

Desert spring wetlands host many endemic species that require aquatic habitat and are isolated by the surrounding xeric terrestrial habitat. The Dixie Valley Toad (Anaxyrus williamsi) is a recently described anuran species endemic to desert spring wetlands in the Dixie Valley, Churchill County, Nevada, USA. Given this species was only recently recognized as distinct from Anaxyrus boreas, little is known about its ecology and habitat requirements. These data represent the results of surveys for Dixie Valley Toads conducted from April 2018 to May 2021 in Churchill County, Nevada, USA and associated covariates from surveys and study sites. The potential wetland habitat for the Dixie Valley Toad was divided into 20...

These data include egg mass counts and adult capture-mark-recapture histories for Foothill Yellow-legged frogs (Rana boylii) at two streams in northern California. Data were collected from the South Fork Eel River and its tributary, Fox Creek, from 1993-2019. Data from Hurdygurdy Creek were collected from 2002-2008. This code and data support the following publication: Rose, JP, Kupferberg, SJ, Wheeler, CA, Kleeman, PM, and Halstead BJ. 2021. Estimating the survival of unobservable life stages for a declining frog with a complex life history. Ecosphere. 12(2):e03381.
Species distributions are governed by processes occurring at multiple spatial scales. For species with complex life cycles, the needs of all life stages must be met within the dispersal limitations of the species. Multi-scale processes can be particularly important for these species, where small-scale patterns in specific habitat components can affect the distribution of one life stage, whereas large-scale patterns in land cover might better explain the distribution of other life stages. Using a conditional multi-scale model, we evaluated which aspects of the landscape and local environment are most strongly related to occupancy patterns of western spadefoots (Spea hammondii). These data describe the survey, pool,...

Occupancy models provide a reliable method of estimating species distributions while accounting for imperfect detectability. The cost of accounting for false absences is that detection and nondetection surveys typically require repeated visits to a site or multiple-observer techniques. More efficient methods of collecting data to estimate detection probabilities would allow additional sites to be surveyed for the same amount of effort, which would support more precise estimation of covariate effects to improve inference about underlying ecological processes. Time-to-detection surveys allow the estimation of detection probability based on a single site visit by one observer, and therefore might be an efficient technique...

These data include field-collected observations of the occurrence of adult and larval amphibians at 174 sites in 14 watersheds at Yosemite National Park from 2007 through 2021. Also included in the data are potential variables affecting site occurrence, probability of reproduction, and probability of detection of amphibians, including static site-specific variables like site size and elevation, and dynamic variables including surveyors, when surveys occurred, and site- and year-specific weather variables. These data were used to fit the models in the accompanying publication and can be used with the associated code to replicate the results found in the publication. These data support the following publication:...
