Mapping of terrestrial vertebrates focuses on linking a spatial representation of species-habitat matrices to geographic distribution. Each model is a combination of distribution from regional and state references in association with contiguous appropriate habitats. Ranges for all species were based on 8-digit HUCs. Habitats were based on a raster SWReGAP 1 acre MMU land cover data set, with hydrology habitats added in from USGS NHD dataset directly or through modeling. Habitat association information was obtained from various state, regional, and national references with updates from scientific literature. This portion of the Southwest Regional Gap Analysis Project produced predicted habitat distribution maps for...

This data set contains mark-recapture information for individuals of Dicamptodon tenebrosus and Ascaphus truei marked for individual recognition. Amphibians represented in this data set were captured in 14 first-order perennial and seasonally intermittent streams in the East Fork of the South Fork of the Trask River in the northern Oregon Coast Range. Individuals are larval and mature aquatic Dicamptodon tenebrosus and larval Ascaphus truei. Of the Ascaphus truei larvae only individuals thought to be in their first summer when first captured are included (these are individuals whose knees had yet to emerge from under the anal flap or fold).

The data presented includes chloride concentration and specific conductance in surface water collected from 33 wetlands in the Williston Basin of Montana and North Dakota, 2015-2017 as well as count data for three species of amphibians captured at each wetland. Data also includes concentrations of metals in bed sediment and larval amphibians collected from 32 and 12 wetlands, respectively in 2015-2016. Abundance of barred tiger salamanders (Ambystoma mavortium), boreal chorus frogs (Pseudacris maculata), northern leopard frogs (Lithobates pipiens) was estimated at 33 wetlands from 2015-2017. Surface water was collected in the summer from each wetland in 2015-2017 at the same time as the amphibian surveys and analyzed...
This Data Release represents geospatial and tabular data for a study investigating linkages between local terrain and wetland hydroperiod and was supported by the U.S. Geological Survey (USGS) Amphibian Research and Monitoring Initiative (ARMI). This dataset contains wetland water level data from Saint Marks National Wildlife Refuge (SMNWR). Data include records of water level and water temperature measurements from select wetlands beginning in July 2010 and ending in 2019. Not all wetlands span this entire period as different phases of studies resulted in different time periods of data collection. Instrumentation included a staff gage and a non-vented continuous logging pressure transducer that logged data at 1-hour...
Biological endpoints for three focal test species [Daphnia magna (mortality), Psuedacris maculata (mortality, growth, and development), and Lemna gibba (growth)] in response to exposure to reconstituted or field-collected water under laboratory conditions. Field-collected waters were collected from wetlands within the Prairie Pothole Region (PPR) of the United States. Reconstituted water was mixed to mimic some chemistry of surface water from brine contaminated PPR wetlands. Also included are water quality and chemical concentration data from all assays.
Conclusions: Few species were in fact influenced by grassland amount or fragmentation. In contrast, distance to edge and local vegetation characteristics had significant effects on densities and nest success of many species. Thresholds/Learnings: Great Plains toads thrive when >75% of the landscape is composed of native prairie components (i.e. shrubs, graminoids, riparian areas, lakes, wetlands, and trees) . Synopsis: In Alberta, Great Plains toads are found in the dry mixed grass of the southeastern corner of the province. Typical breeding habitat tends to be in shallow ponds with relatively fresh, clear water in sandy soil. In this report habitat suitability was evaluated for the Great Plains toad according...

This data set shows PFLCC's Freshwater Forested Wetland Priority Resource along with amphibian species taken from the 2011 Atlas of Reptiles and Amphibians (FWC) which shows occurrence records based on FWC data. Sensitive Species were selected (based on the Masters Thesis of J. Surdick, Jr, 2005 (University of Florida) that determined amphibian species.

The raster data in the geodatabase represent range-wide habitat suitability model predictions for five species of herpetofauna: gopher tortoise (Gopherus polyphemus), southern hognose snake (Heterodon simus), Florida pine snake (Pituophis melanoleucus mugitus), gopher frog (Lithobates capito), and striped newt (Notophthalmus perstriatus). Collectively, the habitat suitability rasters extend across the range of these species in the Southeast US, including areas in Louisiana, Mississippi, Alabama, Florida, Georgia, South Carolina, and North Carolina. This assessment was conducted by the USGS Cooperative Fish & Wildlife Research Unit at the University of Georgia in collaboration with other partners. Habitat suitability...

From 2002-2006, we used a variety of sampling techniques to survey the amphibians and water chemistry of Lower Suwannee National Wildlife Refuge in Florida’s Big Bend region. We recorded 23 amphibian species, 19 frogs and 4 salamanders. Species richness was lower than in areas of the coastal Big Bend region to the north. Amphibians occupied a wide variety of habitats and appeared tolerant of the generally acidic conditions of many of the wetlands. Although additional species may yet be found in LSNWR, this survey provides a historic baseline for assessing future status and trends of amphibian populations.

Background information. Settlement funds from the California Gulch Superfund site have been used to improve instream aquatic habitat and increase brown trout (Salmo trutta) populations in the Arkansas River. The upper Arkansas River Basin is a high-elevation mountain river that supports trout populations. Historically characterized by a relatively narrow channel with fast moving water, recent degradation of the upper Arkansas River due to historic land-use practices have contributed to an altered river channel and a decrease in important habitat features for trout, such as deep-water pools. This restoration project was designed to address three major issues: bank erosion, altered river channel morphology, and degraded...

These data represent occupancy surveys conducted in long-term monitoring sites in Yosemite National Park in 2018 for three anurans, the Yosemite Toad (Anaxyrus canorus), the Sierran Treefrog (Pseudacris sierra), and the Sierra Nevada Yellow-legged Frog (Rana sierrae). The data include independent double-observer surveys and time-to-detection data to calculate detection probabilities and account for false negatives, or the failure to detect a species at a site where it occurs. 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.

Data are the result of fixed-area, time-constrained searches for terrestrial salamanders within and nearby a wildfire-affected area of the Willamette National Forest, OR. The spatial extent of the study was within one kilometer of the border of the Clark fire that burned an area of 2,009 ha in 2003. Site surveys occurred during March and April, 2005. An important feature of the data is that 100m2 sub-plots (nested within plots) were repeatedly searched for terrestrial salamanders independently up to nine times so that variation in the probability of capture could be estimated and accounted for concurrent with estimates of occupancy probability.
There are two datasets included in this entry. The diurnal dataset contains 28 columns of data collected during transects surveys. The nocturnal dataset contains 52 columns. We randomly select 56 sites, each 50 m in length, from 37,968 m of transects spanning the island that were originally created for bird surveys in 1982 through the cooperative efforts of the U.S. Fish and Wildlife Service, the Department of Natural Resources of CNMI, and the U.S. Forest Service. For diurnal surveys, 56 transects were surveyed twice per day for 1–3 consecutive days resulting in six survey occasions. For nocturnal surveys, we surveyed 51 of the 56 transects 4 times per night for 1–3 consecutive nights resulting in 12 survey occasions....
