From 2004 to 2006, we used a variety of sampling techniques to survey the amphibians of Savannah National Wildlife Refuge (SNWR), a large protected area straddling the lower portions of the Savannah River on the border between South Carolina and Georgia, USA. We documented 22 amphibian species, 15 frogs and 7 salamanders, with a possible 23rd species present. Amphibians occupied a variety of habitats and appeared tolerant of the mildly acidic and low oxygen conditions of many of the wetlands. This initial survey provides a historic baseline for monitoring amphibian populations as areas adjacent to the refuge.

Approximately 90% of pine rockland habitat in South Florida and the Florida Keys, USA, has been lost, fragmented, and degraded due to urbanization and other anthropogenic disturbances. Low-lying islands and coastal areas are also becoming increasingly vulnerable to sea-level rise and high tide flooding, which is rapidly increasing in frequency, depth, and extent, putting these areas and the pine rockland habitat they contain at particular risk to these threats. We evaluated changes in habitat under future sea level rise conditions and human development for two species of snakes that are endemic to the pine rocklands, Rim Rock Crowned snake (Tantilla oolitica) and Key Ringneck snake (Diadophis punctatus acrinus),...
This dataset provides the results of a national survey of the conterminous U.S. for the salamander chytrid fungus Batrachochytrium salamandrivorans (Bsal) conducted by the U.S. Geological Survey Amphibian Research and Monitoring Initiative from May 2014 to August 2017. Sites were sampled by capturing amphibians by hand or by traps or nets that were then swabbed individually using methods that prevent sample contamination. All swabs were then analyzed using a real-time TaqMan PCR for detection of B. salamandrivorans on the extracted DNA. The data consist of locality information and data on the individual sampled, as well as the result of the test for B. salamandrivorans. No cases of B. salamandrivorans were detected...

These data are meant to support a publication "Disentangling direct and indirect effects of extreme events on coastal wetland communities" in the Journal of Animal Ecology. This dataset contains both amphibian and fish observations based on our use of plastic minnow traps. Additionally we present (specific) conductance values observed during our trapping periods.

Sand beaches are dynamic, making it difficult to accurately predict habitat loss from sea level rise (SLR). We mapped sand beach habitat based on two datasets - a remotely sensed land cover and hand-digitized aerial imagery collected concurrently with digital elevation data. Data include the predicted area of beach habitat still above water (units = number of pixels) from SLR per decade, for 3 SLR scenarios, based on two mapping methods, for 12 barrier island beaches and 4 control islands off Florida's Gulf Coast.
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.

Hurricane Michael impacted the gulf coast of the southeastern USA in October 2018. During this storm, St. Marks National Wildlife Refuge, located along the northern Gulf of Mexico’s coast in the panhandle region of Florida, experienced storm surge that was 2.3 to 3.3 m above sea level. Storm surge pushed sea water into some ephemeral freshwater ponds used for breeding by the federally-threatened Frosted Flatwoods Salamander (Ambystoma cingulatum). Not all breeding wetlands were inundated by storm surge but, of those that were, conductivity was 11.2 to 216.7 times greater than in spring 2018. After the storm, specific conductance varied from 80 to 23,100 µS/cm (compared to 75 to 445 µS/cm in Spring 2018), setting...
The striped newt (Notophthalmus perstriatus) is a small salamander that occurs in xeric habitats (e.g. scrub, sandhill, and dry flatwoods) of the lower coastal plain and northern peninsular Florida. Like most North American amphibians, the striped newt has a biphasic life cycle (i.e., aquatic egg and larval stages, as well as terrestrial juvenile/eft, and adult stages, and requires wetlands for reproduction. Striped newts, and a few other salamanders, are capable of adding an alternative life history pathway called paedogenesis; i.e.,larvae develop gonads and are able to reproduce without leaving the water. Paedomorphs can still transform into terrestrial forms at later time. Paedomorphosis affords benefits...

This dataset includes hydrological measurements of 300 US temporary wetlands from 2004-2014.
The primary habitats for insular mole skinks in Florida are sand beaches, beach berms, and dunes, making them particularly vulnerable to sea level rise (SLR) and storm surge. We used the most recent SLR projections, high resolution lidar-based digital elevation models, a combination of a comprehensive land cover and hand-digitized aerial imagery, and the latest storm surge simulations to predict the impact of SLR and storm surge on habitat for insular mole skinks in Florida, by decade, from 2030 – 2150 using a modified bathtub model. Data include the predicted area of mole skink habitat still above water (units = number of pixels) from SLR per decade for 3 SLR scenarios, for the Florida Keys Mole Skink (Plestiodon...
