Five concentrations of CO2 were administered to twenty-four test tanks at a water temperature of 5\u00b0C. Initially, Red Swamp Crayfish (Procambarus clarkii) were intended to be the test species used in the study. However, problems with obtaining a healthy population of RSC occurred, so Virile Crayfish (Faxonius virilis) were used instead. These datasets include water quality, biometric, behavioral observation, and CO2 titration data from two trials.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1RCZTPC", "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.684742dfd4be024da9d873d2.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_684742dfd4be024da9d873d2", "keyword": ["USGS:684742dfd4be024da9d873d2", "biota", "carbon dioxide", "invasive species", "pest control", "red swamp crayfish", "virile crayfish"], "modified": "2025-06-11T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-91.254845, 43.867719, -91.248965, 43.869389", "theme": ["geospatial"], "title": "Acute Toxicity of Carbon Dioxide to Crayfish"}
