NEON Biorepository Benthic Macroinvertebrate Collection (Fluid Preserved Oligochaetes)

Collected samples are separated into fluid-preserved general macroinvertebrates, fluid-preserved chironomids, fluid-preserved oligochaetes, and slide-mounted chironomids and oligochaetes. Taxonomic identifications are generated from subsamples of each group.

This sample type contains taxonomic identifications derived from subsample analysis of fluid-preserved oligochaetes. Sampling 3 sampling bouts per year (spring, summer, fall) 8 locations at each NEON site 5 in dominant habitat type (wadeable stream) or littoral area (lake and river) 3 in sub-dominant habitat type (wadeable streams) or pelagic area (lakes and rivers) 11 samples collected per bout total 8 morphology samples (1 per location) 3 DNA samples (3 dominant/littoral locations) Bouts 1 & 3 DNA samples archived unprocessed Bout 2 samples extracted and sequenced
