Researchers are usually unable to see every individual of a population or to even detect some entire populations. Ignoring this imperfect detectability can bias estimates of population characteristics, such as probability of occurrence, abundance, survival, recruitment, and population growth rate. Furthermore, the precision with which these population characteristics are estimated is dependent on detection probabilities (the probability that at least one individual of a species is detected during a survey, given that the species occurs where the survey is conducted) and capture probabilities (the probability that a given individual is observed or captured during a single survey); greater detection and capture probabilities result in less uncertainty about the values of population characteristics and a greater ability to evaluate the effects of variables or experimental treatments on the population characteristic(s) of interest.\nDetection and capture probabilities for giant gartersnakes (Thamnophis gigas) are very low, and successfully evaluating the effects of variables or experimental treatments on giant gartersnake populations will require greater detection and capture probabilities than those that had been achieved with standard trap designs. Previous research identified important trap modifications that can increase the probability of snakes entering traps and help prevent the escape of captured snakes. The purpose of this study was to quantify detection and capture probabilities obtained using the most successful modification to commercially available traps to date (2015), and examine the ability of realized detection and capture probabilities to achieve benchmark levels of precision in occupancy and capture-mark-recapture studies.", "description": "iv, 36 p.", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Halstead, Brian J. bhalstead@usgs.gov", "givenName": "Brian J.", "familyName": "Halstead", "email": "bhalstead@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-5535-6528", "url": "https://orcid.org/0000-0002-5535-6528"}, "affiliation": [{"@type": "Organization", "name": "Western Ecological Research Center", "url": "https://www.usgs.gov/centers/werc"}, {"@type": "Organization", "name": "Coop Res Unit Seattle"}]}, {"@type": "Person", "name": "Skalos, Shannon M. sskalos@usgs.gov", "givenName": "Shannon M.", "familyName": "Skalos", "email": "sskalos@usgs.gov", "affiliation": [{"@type": "Organization", "name": "Western Ecological Research Center", "url": "https://www.usgs.gov/centers/werc"}]}, {"@type": "Person", "name": "Casazza, Michael L. mike_casazza@usgs.gov", "givenName": "Michael L.", "familyName": "Casazza", "email": "mike_casazza@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-5636-735X", "url": "https://orcid.org/0000-0002-5636-735X"}, "affiliation": [{"@type": "Organization", "name": "Western Ecological Research Center", "url": "https://www.usgs.gov/centers/werc"}]}, {"@type": "Person", "name": "Wylie, Glenn D. glenn_wylie@usgs.gov", "givenName": "Glenn D.", "familyName": "Wylie", "email": "glenn_wylie@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-7061-6658", "url": "https://orcid.org/0000-0002-7061-6658"}, "affiliation": [{"@type": "Organization", "name": "Western Ecological Research Center", "url": "https://www.usgs.gov/centers/werc"}]}], "funder": [{"@type": "Organization", "name": "Western Ecological Research Center", "url": "https://www.usgs.gov/centers/werc"}], "spatialCoverage": [{"@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/6252001"}, {"@type": "Place", "additionalType": "state", "name": "California", "url": "https://geonames.org/5332921"}, {"@type": "Place", "additionalType": "unknown", "name": "Sacramento Valley", "url": "https://geonames.org/5389639"}, {"@type": "Place", "geo": [{"@type": "GeoShape", "additionalProperty": {"@type": "PropertyValue", "name": "GeoJSON", "value": {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[-122.33551025390625, 38.50519140240354], [-122.33551025390625, 39.61626788999701], [-121.4923095703125, 39.61626788999701], [-121.4923095703125, 38.50519140240354], [-122.33551025390625, 38.50519140240354]]]}}]}}}, {"@type": "GeoCoordinates", "latitude": 39.06072964620027, "longitude": -121.91390991210939}]}]}
