Subsample of Carabid adults from pitfall sampling (NEON sample class: bet_archivepooling_in.subsampleID.bet). Ground beetle abundance and diversity are sampled via pitfall trapping at regular intervals by NEON field technicians at core and relocatable terrestrial sites. Following trap collection, all beetles from the family Carabidae are sorted by NEON technicians and identified to species or morphospecies. A subset of collected Carabidae are pointed or pinned, while other specimens (non-pinned/non-pointed carabids, invertebrate bycatch, and vertebrate bycatch) are stored in 95% ethanol for archiving, and may be pooled into a single archive vial per plot. Regardless of storage method, all collections data are reported at a per trap resolution. A subset of pinned ground beetles (up to 467 per site per year) are sent to an expert taxonomist for secondary identification. Identifications performed on these individuals may be used to estimate uncertainty in parataxonomist identification by NEON technicians.See TOS Protocol and Procedure: Ground Beetle Sampling and TOS Science Design for Ground Beetle Abundance and Diversity (https://data.neonscience.org/documents) for more information about this sample class.
