This species often persists in habitat islands throughout much of its distribution due to extensive habitat loss and distance-limited\ndispersal. These data are from 102 individual Eastern Massasauga Rattlesnakes sampled at Bois Blanc Island, Michigan and genotyped at 15 microsatellite loci.  Samples were collected as part of a study to examine functional connectivity for the Eastern Massasauga. We found that the entire island population\nexhibited weak genetic structuring with spatially segregated variation in effective migration and genetic diversity.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9HJW59U", "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.5fc8f3b0d34e4b9faad8a119.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5fc8f3b0d34e4b9faad8a119", "keyword": ["Bois Blanc island", "Lake Huron", "Michigan", "USGS:5fc8f3b0d34e4b9faad8a119", "biological population management", "biota", "endangered species", "environment", "evolution", "genetic diversity", "genetics", "genotype", "loci", "microsatellite"], "modified": "2025-01-24T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-84.5940, 45.7162, -84.3503, 45.8216", "theme": ["geospatial"], "title": "Genotype Data for Eastern Massasauga Rattlesnakes (Sistrurus catenatus) from Bois Blanc Island, Michigan at 15 Microsatellite DNA Loci"}
