Data include weekly collections from traps (unknown trapping range) and monthly collections from 1 sq. meter sampling grids.</p>\\n<p>Resources in this dataset:</p>\\n<ul>\\n<li>\\n<p>Resource Title: Monthly box sampling data\\nFile Name: boxdat_full2.csv\\nResource Description:\\npond: individual ponds sampled\\nbank: pond bank sampled/location\\nptype: FR = fingerling pond, FF = foodfish pond\\nsnail: snail taxa\\nmonth: month (as date) sampled\\nabundance: raw counts from snail traps (truncated at 100 individuals per taxa)\\ntemp: water temperature (C)\\noxygen: water dissolved oxygen (mg/L)\\ntan: total ammonia - nitrogen (mg/L)\\nno2: nitrite (mg/L)\\nchloride: total water chlorides (mg/L)</p>\\n</li>\\n<li>\\n<p>Resource Title: Weekly trap collections\\nFile Name: trapdat_full.csv\\nResource Description:\\nweek: week of sampling (typically occurred on Tuesday of that week)\\npond: individual ponds sampled\\nptype: FR = fingerling pond; FF = foodfish pond\\ntrap: pond bank location of trap (cardinal directions)\\nsnail: snail taxa\\nabundance: raw counts of snails collected from each trap (truncated at 100 individuals per taxa)\\nchloride: total chlorides in the water (mg/L)\\ntan: total ammonia - nitrogen (mg/L)\\nno2: total ammonia - nitrite (mg/L)\\nm_temp: mean water temp (C) across all ponds\\nm_oxy: mean dissolved oxygen (mg/L) across all ponds</p>\\n<div><br>Resources in this dataset:</div><br><ul><li><p>Resource Title: Monthly box sampling data.</p> <p>File Name: boxdat_full2.csv</p><p>Resource Description: pond: individual ponds sampled\\nbank: pond bank sampled/location\\nptype: FR = fingerling pond, FF = foodfish pond\\nsnail: snail taxa\\nmonth: month (as date) sampled\\nabundance: raw counts from snail traps (truncated at 100 individuals per taxa)\\ntemp: water temperature (C)\\noxygen: water dissolved oxygen (mg/L)\\ntan: total ammonia - nitrogen (mg/L)\\nno2: nitrite (mg/L)\\nchloride: total water chlorides (mg/L)\\n</p></li><br><li><p>Resource Title: Weekly trap collections.</p> <p>File Name: trapdat_full.csv</p><p>Resource Description: week: week of sampling (typically occurred on Tuesday of that week)\\npond: individual ponds sampled\\nptype: FR = fingerling pond; FF = foodfish pond\\ntrap: pond bank location of trap (cardinal directions)\\nsnail: snail taxa\\nabundance: raw counts of snails collected from each trap (truncated at 100 individuals per taxa)\\nchloride: total chlorides in the water (mg/L)\\ntan: total ammonia - nitrogen (mg/L)\\nno2: total ammonia - nitrite (mg/L)\\nm_temp: mean water temp (C) across all ponds\\nm_oxy: mean dissolved oxygen (mg/L) across all ponds</p></li></ul>\\n</li>\\n</ul><p></p>\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://ndownloader.figshare.com/files/44540213\", \"format\": \"csv\", \"mediaType\": \"text/plain\", \"title\": \"boxdat_full2.csv\"}, {\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://ndownloader.figshare.com/files/44540216\", \"format\": \"csv\", \"mediaType\": \"application/csv\", \"title\": \"trapdat_full.csv\"}], \"identifier\": \"10.15482/USDA.ADC/1529417\", \"keyword\": [\"ARS\", \"Biomphalaria\", \"Mississippi\", \"NP106\", \"Planorbella\", \"aquaculture\", \"catfish\", \"data.gov\", \"snails\"], \"license\": \"https://www.usa.gov/publicdomain/label/1.0/\", \"modified\": \"2026-03-24\", \"programCode\": [\"005:040\"], \"publisher\": {\"@type\": \"org:Organization\", \"name\": \"Agricultural Research Service\"}, \"spatial\": \"{\\\"type\\\": \\\"Polygon\\\", \\\"coordinates\\\": [[[-90.591064654291, 34.398978365558], [-90.977783538401, 33.948144962042], [-91.17114264518, 33.626741513272], [-91.144775189459, 33.223294872108], [-91.12719733268, 32.96558229362], [-90.617431439459, 32.995073490085], [-90.221923626959, 32.995073490085], [-89.826415814459, 33.098214777724], [-89.931884966791, 33.897093251214], [-90.591064654291, 34.398978365558]]]}\", \"temporal\": \"2021-05-23/2021-09-26\", \"title\": \"Data from: Evaluation of a snail trap prototype for monitoring the intermediate gastropod hosts of Bolbophorus spp. in commercial catfish ponds of the southeastern United States\"}","source_transform":null,"status":"success"}
