NEON Biorepository Benthic Macroinvertebrate Collection (Unsorted Bulk Sample)

Unprocessed macroinvertebrate samples collected from wadeable streams, rivers, and lakes. Samples from bouts 1 and 3 are archived without analysis. Samples from bout 2 are sequenced, and the resulting DNA extracts are archived. Sampling 3 sampling bouts per year (spring, summer, fall) 8 field locations per NEON site 5 in dominant habitat (wadeable streams) or littoral zone (lakes/rivers) 3 in sub-dominant habitat (wadeable streams) or pelagic zone (lakes/rivers) 11 samples collected per bout total 8 morphology samples (1 per location) 3 DNA samples from dominant/littoral locations Bouts 1 & 3 DNA samples archived unprocessed Bout 2 samples extracted and sequenced Methods Habitat-appropriate sampling gear (e.g., Surber, Hess, corer, kicknet, D-frame sweep, petite ponar) Samples collected from natural substrate surface Preservation Preserved in 70-95% ethanol Maintained in temperature- and humidity-controlled storage
