This dataset includes stable Parameter-elevation Relationships on Independent Slopes Model (PRISM) climate model output (Band Interleaved by Line [.bil] image files) data from the All Networks 1981 monthly time step (AN81m) model. These have been extracted to the USGS 12-digit Hydrologic Unit (hereafter, HUC-12 basins) spatial grain. Yearly data is available for 83,304 HUC-12 basins in the United States from 1895-2017. Variables include annual precipitation, annual means of maximum and minimum daily average air temperature, maximum daily air temperature in August, minimum daily air temperature in January, daily mean dewpoint temperature, and minimum and maximum daily vapor pressure deficits.

This dataset contains the components of and resultant Rarity and Climate Sensitivity (RCS) values for 90 species of frogs and toads native to the conterminous United States. The RCS metric uses point occurrences to describe area of occurrence, quantifies the variation of climate conditions within that area, and combines and scales the two for a multispecies assessment of intrinsic sensitivity to climate change. The RCS metric was calculated at two geographic extents, the conterminous US and the North American continent. We also used two spatial grains: 1 km buffered occurrence points and small watersheds (Hydrologic Unit Code (HUC) 12 watershed boundaries within and HydroBASIN level 12 watershed boundaries outside...

Abstract (from ScienceDirect): Rarity and life history traits inform multiple dimensions of intrinsic risk to climate and environmental change and can help systematically identify at-risk species. We quantified relative geographic rarity (area of occupancy), climate niche breadth, and life history traits for 114 freshwater fishes, amphibians, and reptiles in the U.S. Pacific Northwest. Our approach leveraged presence-only, publicly available data and traits-based inference to evaluate area of occupancy, climate sensitivity (i.e., climate niche breadth), and a Rarity and Climate Sensitivity (RCS) index of all species across multiple geographic extents, grain sizes, and data types. The RCS index was relatively stable...

We present TRAD: Thermal traits of anurans database for the Southeastern United States, a database of thermal trait values related to physiological (critical thermal minima and maxima, preferred temperature, mass) and behavioral thermoregulation (activity period, retreat emergence temperature, basking temperature, foraging temperature minimum and maximum) for 40 anuran species found within the southeastern United States. Using a species-centric approach, we collated this database by first identifying trait values from large reservoirs of amphibian ecology and natural history and then searching the literature using primarily Web of Science to thoroughly identify available thermal trait data. The TRAD database provides...
