To describe calling activity of Pseudacris crucifer in relation to temperature, precipitation, and wetland water levels, we programmed an acoustic recorder (Wildlife Acoustics) to sample seasonal amphibian calls remotely at study site SC4DAI2 in the St. Croix National Scenic Riverway from 2008 to 2012. We programmed the recorder to sample for five minutes at the top of every hour of every day from late winter/early spring through late summer. We used the Songscape option in Songscope software to generate annual summaries of all of our acoustic samples from SC4DAI2. These summaries included a median dB level for each prescribed frequency within each recording. Pseudacris crucifer, the spring peeper, inhabited SC4DAI2...
These data are associated with an article published in Global Ecology and Conservation (https://doi.org/10.1016/j.gecco.2020.e01173) that describes climate's cascading effects on disease, predation, and hatching sucess in the Yosemite toad (Anaxyrus canorus). The Yosemite toad currently is federally listed as threatened under the U.S. Endanered Species Act based upon reported population declines and vulnerability to climate and other global-change factors. The species occurs only in California’s central Sierra Nevada at medium to sub-alpine elevations. Lands throughout its range largely are protected from development, but climate and other global-change factors potentially can limit populations.

We produced this data set as part of a larger, integrated study to assess the statuses of populations of Anaxyrus canorus and the causes of observed effects on fitness at field sites, primarily in Yosemite National Park near Tioga Pass, from 1996 to 2001. To assess and document the depths to the tops of individual A. canorus and Pseudacris regilla egg masses and to the sediments, we measured water depths at masses of both species. We used a meter stick to measure the depth (nearest mm) where female A. canorus deposited individual egg masses, and the distance from the water’s surface to the tops of those masses, at several breeding sites across 1996, 1998, 1999, and 2000. We did the same for egg masses of P. regilla...

The comma-delimited fields in this dataset provide values for the remotely sensed variables analyzed for landscape blocks described in the paper, "Multi-year data from satellite- and ground-based sensors show details and scale matter in assessing climate’s effects on wetland surface water, amphibians, and landscape conditions," by Sadinski et al. (submitted). The field labeled “BlockSite” links the records in this file with a set of boundaries in a shapefile called “Study_Block_Boundaries.shp” The records represent weekly measurements of normalized difference vegetation index (BlockNDVI) values and total evapotranspiration (BlockETmm), as well as the annual snow-off date (BlockDOYsnowfree) for the study blocks from...
We produced this data set as part of a larger, integrated study to assess the statuses of populations of Anaxyrus canorus and the causes of observed effects on fitness at field sites, primarily in Yosemite National Park near Tioga Pass, from 1996 to 2001. ENCLOSURES We used field enclosures to test the hypothesis that exposure to ambient UV-B caused embryo mortality in 1996 and 1998. We covered the top of each enclosure with one or two types of thin plastic sheeting. One type was transparent to the solar spectrum. The other type filtered UV-B below 314 nm (UV-B<314) but was otherwise transparent to solar radiation. Laying both types together over the top of an enclosure did not alter the transmission characteristics...

We produced this data set as part of a larger, integrated study to assess the statuses of populations of Anaxyrus canorus and the causes of observed effects on fitness at field sites, primarily in Yosemite National Park near Tioga Pass, from 1996 to 2001. From 1999 to 2001, we deployed Optic StowAway Temperature loggers (Onset Computer Corporation; Bourne, Massachusetts, USA) to measure minimum daily air temperatures at various breeding sites during embryogenesis for A. canorus. These measurements enabled us to determine relations between air temperatures at individual breeding sites relative to air temperatures measured at the automated weather station in Dana Meadows (DAN) in the heart of our study area. We measured...

This data set contains information on detections of anuran (i.e., frogs and toads) species at six different management areas in the midwestern United States from 2002 to 2012. From 2002 to 2005 anuran communities were surveyed during the day using multiple methods at individual study wetlands—visual encounter surveys, dip net surveys, and calling surveys using multiple observers in most cases. Data are presented from each survey. From 2008 to 2012 amphibian communities were surveyed through detections of vocalizing anurans recorded by automated recording units. Automated recording units recorded five minutes at the top of every hour for the entire field season (typically April through October). Recorder data are...
To relate water levels in these individual wetlands to precipitation and amphibian calling activity
This comma-delimited dataset provides values for the remotely sensed status of snow on/off analyzed for field study sites described in the paper, "Multi-year data from satellite- and ground-based sensors show details and scale matter in assessing climate’s effects on wetland surface water, amphibians, and landscape conditions," by Sadinski et al. (submitted). These data provide an indication of snow presence at the spatial resolution of a 500-m square cell for each eight-day interval beginning in January and ending at the start July of each year from 2008-2012. The source for the data was the MOD10A2 snow product from the Terra Moderate Resolution Imaging Spectroradiometer (MODIS) satellite sensor. We extracted...
We produced this data set as part of a larger, integrated study to assess the statuses of populations of Anaxyrus canorus and the causes of observed effects on fitness at field sites, primarily in Yosemite National Park near Tioga Pass, from 1996 to 2001. We assessed the extent of annual mortality among embryos of A. canorus and Pseudacris regilla variously among breeding sites and years by measuring hatching success in as many individual egg masses as possible, given logistical constraints, at sites we surveyed annually from 1996 to 2000. We visually evaluated each individual embryo in an egg mass in situ while kneeling alongside it immediately before, at, or very soon after hatching (when individual capsules remained...

Telemetry data for 59 Northern Leopard Frogs (Lithobates pipiens) breeding in ponds in Houston and Winona Counties, MN; 2001-2002. Agricultural intensification is causing declines in many wildlife species, including Northern Leopard Frogs (Lithobates pipiens). Specific information about frog movements, habitat selection, and sources of mortality can be used to inform conservation-focused land management and acquisition. We studied Northern Leopard Frogs in southeastern Minnesota, part of the Driftless Area ecoregion, characterized by hills and valleys and a mix of agriculture, forests, small towns and farmsteads. In this area, small farm ponds, originally built to control soil erosion are used by the species for...

To better understand relations of annual calling phenophases for Pseudacris crucifer, and of the first calls of the season for Hyla chrysoscelis/versicolor, to the timing of the start of the calling season, we compared these dynamics for six wetlands in the St. Croix National Scenic Riverway from 2008 to 2012. We installed an acoustic recorder at each site prior to the start of each calling season and programmed it to record for five minutes at the top of every hour until late summer. We then used the Songscape option in Songscope software to generate annual summaries of all acoustic files recorded at each site. We created contour plots of the summarized median dB values across bandwidths in each recording and then...
To relate water levels in our study wetlands to temperature, precipitation, wetland water depth, and amphibian calling activity, we installed one pressure logger in the deepest spot we could find in each wetland. Soon after thawing conditions allowed, we drove a plastic pipe (anchor pipe) into the sediments at the deepest location and secured another pipe to it that contained one pressure logger (Global Water Model 14 and 15 [College Station, TX, USA] or Onset Computer Corporation Model U20-001-04 [Bourne, MA, USA]) suspended approximately 2.5 cm above the sediments. We installed additional individual pressure loggers in the upper part of the logger pipes (in air) at select locations to measure barometric pressure...

The polygons in this shapefile accompany the paper, “Multi-year data from satellite- and ground-based sensors show details and scale matter in assessing climate’s effects on wetland surface water, amphibians, and landscape conditions,” by Sadinski et al. (submitted). The paper describes relations between climate dynamics and key ecological conditions and processes on wetland-upland landscapes in > 30 sites distributed across four study areas in the midwestern United States. The variables studied included both ground- and satellite-based measures. The polygons in this shapefile pertain to the latter and provide the boundaries of 4-km2 blocks that subsume the field sites and provide a landscape perspective for the...

To help determine when winter conditions were changing to spring conditions annually in our four study areas, we determined the first eight-day interval (in accordance with the scale limitations of satellite data we used to assess the presence of snow) during which the first amphibian of the season called at each of our study wetlands in those areas. To do this, we examined contour plots of summaries of all the acoustic data we collected at that site in a given year to identify the unique call signatures of individual amphibian species by date and time. When necessary due to potential confounding on a contour plot, we also examined relevant individual five-minute recordings aurally and visually to confirm whether...

We produced this data set as part of a larger, integrated study to assess the statuses of populations of Anaxyrus canorus and the causes of observed effects on fitness at field sites, primarily in Yosemite National Park near Tioga Pass, from 1996 to 2001. We assessed the three general categories (early, mid, and late) for the developmental stage at which embryos of A. canorus died among various breeding sites from 1999 to 2001. We visually evaluated each individual embryo in an egg mass in situ while kneeling alongside it immediately before, at, or very soon after hatching (when individual capsules remained from hatched embryos and when any remnants of dead embryos typically still were visible). We did not assess...

To assess embryo mortality, we visually evaluated each individual embryo in an egg mass in situ while kneeling alongside it immediately before, at, or very soon after hatching (when individual capsules remained from hatched embryos and when any remnants of dead embryos typically still were visible). We did not assess mortality in any egg masses that had deteriorated too far to evaluate embryos. In 2001, a limited number of field personnel caused us to estimate...

We produced this data set as part of a larger, integrated study to assess the statuses of populations of Anaxyrus canorus and the causes of observed effects on fitness at field sites, primarily in Yosemite National Park near Tioga Pass, from 1996 to 2001. We conducted a field experiment in 1999 to test for effects of enclosing embryos of A. canorus and moving them to slightly deeper water, thereby reducing the potential for exposure to ice and freezing temperatures, on hatching success at five breeding sites. We split freshly laid egg masses approximately into halves. We left one indiscriminately chosen half of each mass where it was deposited originally (replicates of which were scattered among the shallow waters)...
