A combination of methods were used to assess the movement of salamanders to and from the breeding pond. Environmental variables such as air and water temperature, water salinity, and relative humidity were also collected during the study. A traffic counting device was also installed at the edge of the study area to monitor the number of vehicles passing through the area during migration events. Surveys to quantify egg masses in the breeding pond were also completed during the study.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9Q3NJPY", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.5ed54dc382ce2832f047ef9a.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5ed54dc382ce2832f047ef9a", "keyword": ["Amphibian", "Habitat fragmentation", "Hinds County", "Human impact", "Mississippi", "Reproductive behavior", "Salamanders", "Seasonal movements", "USGS:5ed54dc382ce2832f047ef9a", "United States"], "modified": "2025-03-25T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-90.7200, 32.0500, -90.0600, 32.5600", "theme": ["geospatial"], "title": "Data from a road ecology study of Spotted Salamanders along the Natchez Trace Parkway, Mississippi, in 2012-2013"}
