Benthic Macroinvertebrate Collection (Unsorted Bulk Sample) (NEON-BMIC-UB)

SAMPLES ARE CURRENTLY UNAVAILABLE. Please contact the NEON Biorepository for information about when these samples will become available. This collection contains unsorted bulk benthic macroinvertebrate samples collected in the field (NEON sample class: inv_fielddata_in.geneticSampleID). Benthic macroinvertebrate samples are collected three times per year at wadeable stream, river, and lake sites during aquatic biology bout windows, roughly in spring, summer, and fall. Samples are collected using the most appropriate sampler for the habitat type, including Surber, Hess, hand corer, modified kicknet, D-frame sweep, and petite ponar samplers. Macroinvertebrates are sampled using a percent-based macrohabitat approach. In wadeable streams, samples are collected in the two most dominant habitat types (e.g. riffles, runs, pools, step pools) within each 1 km-long wadeable stream site. In lakes, samples are collected near the buoy, inlet, and outlet sensors using a petite ponar, and in littoral areas using a D-frame sweep. In rivers, samples are collected near the buoy and two other deep-water locations using a petite ponar sampler, and in littoral areas using a D-frame sweep or large-woody debris sampler. Field protocols differ depending on the habitat and substrate being sampled. However, all samples are collected from the surface of the natural substratum in each habitat. Samples are preserved in ethanol in the field, and returned to the domain support facility for a preservative change prior to shipping. The DNA samples from bout 2 (summer) are sent to an external laboratory for metabarcoding. The unsorted bulk DNA samples from bout 1 (spring) and bout 3 (autumn) are archived for future research. Unsorted bulk macroinvertebrate samples are preserved in 70-95% ethanol and archived in a temperature (17-18°C) and humidity controlled environment.
