Annotated bibliography of grazing effects on amphibians and their habitats (ver. 2.0, February 2022)

This database contains literature citations and associated summaries pertaining to livestock grazing effects on amphibians and their habitats, with an emphasis on the Oregon spotted frog (Rana pretiosa) and other listed/sensitive wetland-breeding amphibians in the western United States. This is not meant to be an exhaustive list, nor did we perform a systematic meta-analysis; rather, literature records were included based on topical relevance. *HINT: If you are looking for the database SEARCH TOOL, scroll down to 'Attached Files' and download 'Annotated_bibliography_with_search_tool.accdb.'

Comparative rates of rehydration from soil in two species of toads, Bufo boreas and Bufo punctatus

1. 1. The rates of rehydration from a varying soil particle size was investigated for two species of toads, Bufo boreas and Bufo punctatus. 2. 2. Both species of toads were found to gain comparatively equal rates of water per unit of surface area, about 40 mg/cm2 per hr. However, the larger surface area to volume ratio of B. punctatus allows this anuran to regain its deficit at a significantly faster rate than B. boreas. B. punctatus showed rates of about 3 per cent standard weight gain per hr while B. boreas showed rates of about 1.5 per cent standard weight gain per hr. 3. 3. It is proposed that a reduced size (i.e. increased surface area to volume ratio) may be an important adaptation to xeric environments. Published...

Site and Survey Data for Dixie Valley Toads in Churchill County, Nevada, 2019

These data include site- and survey-specific information for occupancy surveys of Dixie Valley Toads (Anaxyrus williamsi) collected in the Dixie Valley, Churchill County, Nevada, in May 2019. The data include both multiple surveys of the same sites and time-to-detection information to quantify detection probabilities and account for imperfect detection in assessments of Dixie Valley Toad occupancy. These data support the following publication: Schimel, D.S., 2018, Editorial: Ecological Applications, v. 28, no. 4, p. 869–870, https://doi.org/10.1002/eap.1735.

Amphibian Observations

The dataset contains the recorded locations of amphibians collected in Southeast Alaska from 1867 to 2002. The records were compiled from 15 university and museum collections in the US and Canada. The data contain records for the following species: Northwestern Salamander, Long-toed Salamander, Roughskin Newt, Western Toad, Pacific Chorus Frog, Columbia Spotted Frog, Wood Frog, and the Red-legged Frog.
