Benthic Macroinvertebrate Collection (Taxonomy Subsample) (NEON-BMIC-TS)

This collection contains identified and pooled benthic macroinvertebrates, up to 300 individuals subsampled from each habitat (dominant and subdominant) for each sampling event (NEON sample class: inv_fielddata_in.sampleID, inv_persample_in.mixedInvertVialID). This collection does not contain Chironomids or Oligochaetes, which are removed and archived seperately. 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, but all samples are collected from the surface of the natural substratum in each habitat. Samples are preserved in ethanol in the field, returned to the domain support facility for a preservative change where a small volume of glycerol is added to help keep invertebrates from becoming brittle. Samples are shipped to a taxonomy lab for sorting and identification, including count of each taxon per size class (to nearest mm) and identification to lowest practical taxon (genus or species). Specimens are preserved in 95% ethanol and archived in a temperature (17-18°C) and humidity controlled environment. See related links below for protocols and NEON related data products.
