data_beetle.RdThis 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_beetleA 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.
To process data we:
Remove all non-carabid bycatch samples.
Use the most expert taxonomy when available.
Update abundances based on new taxonomy.
Create a boutID that identifies all trap collection events at a site in the same bout (replacing eventID).
Update collectDate to reference the most common collection day in a bout, maintaining one collectDate per bout.
Create a new trappingDays column for the number of days a trap was set before being collected.
Correct trap days to account for entries where the trap set date was not updated based on a previous collection.
Details of locations (e.g. latitude/longitude coordinates can be found in neon_location).
