SAMPLES ARE CURRENTLY UNAVAILABLE. Please contact the NEON Biorepository for information about when these samples will become available. Genetic extracts from Jonah Ventures for homogenized zooplankton samples collected during zooplankton sampling in lakes (NEON sample class: zoo_dnaExtraction_in.dnaSampleID). Zooplankton are sampled at NEON lake sites three times per year at each site, roughly spring (bout 1), summer (bout 2), and autumn (bout 3). Samples are collected in the water column of lakes using the most appropriate sampler (vertical tow net or Schindler trap) for the depth of water. During each sampling bout, three samples are collected for morphological taxonomy and three samples for DNA. The DNA samples from bout 2 (summer) are sent to an external laboratory for metabarcoding. Genetic extracts in 96-well plates from Jonah Ventures are archived in the NEON Biorepository at -80 degrees Celsius. See AOS Protocol and Procedure: Zooplankton Sampling in Lakes and NEON Aquatic Sampling Strategy (https://data.neonscience.org/documents) for more information about this sample class. NEON datasets (https://data.neonscience.org/home) associated with this sample class include Zooplankton Collection and Zooplankton DNA Barcode. The metabarcoding analysis protocol used by Jonah Ventures is available in the NEON document library (https://data.neonscience.org/documents).
