This dataset was derived from NEON data portal with data product ID 'DP1.10022.001'. Details about this data product can be found at https://data.neonscience.org/data-products/DP1.10022.001.

data_beetle

Format

A data frame (also a tibble) with the following columns:

  • location_id: Location id.

  • siteID: NEON site code.

  • plotID: Plot identifier (NEON site code_XXX).

  • unique_sample_id: Identity of unique samples, usually it has location and date information.

  • trapID: Identifier for trap.

  • observation_datetime: Observation date and time.

  • taxon_id: Accepted species code, based on one or more sources.

  • taxon_name: Scientific name, associated with the taxonID. This is the name of the lowest level taxonomic rank that can be determined.

  • taxon_rank: The lowest level taxonomic rank that can be determined for the individual or specimen.

  • variable_name: The variable name(s) represented by the value column.

  • value: Value of the variable(s) specified by variable_name.

  • unit: Unit of the values in the value column.

  • boutID: Identifier for bout.

  • nativeStatusCode: The process by which the taxon became established in the location. 'A': Presumed absent, due to lack of data indicating a taxon's presence in a given location; 'N': Native; 'I': Introduced; 'UNK': Status unknown.

  • release: Version of data release by NEON.

  • remarks: Remarks (techinical notes) of record.

  • samplingProtocolVersion: The NEON document number and version where detailed information regarding the sampling method used is available; format 'NEON.DOC.######vX'.

  • trappingDays: Decimal days between trap setting and collecting events.

  • latitude: The geographic latitude (in decimal degrees, WGS84) of the geographic center of the reference area.

  • longitude: The geographic longitude (in decimal degrees, WGS84) of the geographic center of the reference area.

  • elevation: Elevation (in meters) above sea level.

  • nlcdClass: National Land Cover Database Vegetation Type Name.

Details

To process data we:

  1. Remove all non-carabid bycatch samples.

  2. Use the most expert taxonomy when available.

  3. Update abundances based on new taxonomy.

  4. Create a boutID that identifies all trap collection events at a site in the same bout (replacing eventID).

  5. Update collectDate to reference the most common collection day in a bout, maintaining one collectDate per bout.

  6. Create a new trappingDays column for the number of days a trap was set before being collected.

  7. Correct trap days to account for entries where the trap set date was not updated based on a previous collection.

Note

Details of locations (e.g. latitude/longitude coordinates can be found in neon_location).
