data_small_mammal.RdThis dataset was derived from NEON data portal with data product ID 'DP1.10072.001'. Details about this data product can be found at https://data.neonscience.org/data-products/DP1.10072.001.
data_small_mammalA 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.
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.
year: Observation year.
month: Observation month.
n_trap_nights_per_bout_per_plot: Number of trap nights per bout per plot.
n_nights_per_bout: Number of nights per bout.
nativeStatusCode: Whether the species is a native or non-native species.
'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.
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.
plotType: NEON plot type in which sampling occurred: tower, distributed or gradient.
nlcdClass: National Land Cover Database Vegetation Type Name.
To process data we:
Remove all records that are designated as "dead", "escaped", or "nontarget".
Remove all records designated as recaptures (i.e., only first captures are retained)
