This table contains a taxonomic list of benthic invertebrates collected from streams in the Upper Mississippi River Basin study unit as part of the USGS National Water Quality Assessemnt (NAWQA) Program. Invertebrates were collected from woody snags in selected streams from 1996-2004. Data Retreival occurred 26-JAN-06 11.10.25 AM from the USGS data warehouse (Taxonomic List Invert http://water.usgs.gov/nawqa/data). The data warehouse currently contains invertebrate data through 09/30/2002. Invertebrate taxa can include provisional and conditional identifications. For more information about invertebrate sample processing and taxonomic standards see, "Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory -- Processing, taxonomy, and quality control of benthic macroinvertebrate samples", at << http://nwql.usgs.gov/Public/pubs/OFR00-212.html >>. Data Retrieval Precaution: Extreme caution must be exercised when comparing taxonomic lists generated using different search criteria. This is because the number of samples represented by each taxa list will vary depending on the geographic criteria selected for the retrievals. In addition, species lists retrieved at different times using the same criteria may differ because: (1) the taxonomic nomenclature (names) were updated, and/or (2) new samples containing new taxa may Phylum Class Order Family Subfamily Tribe Genus Species Taxon Porifera Porifera Cnidaria Hydrozoa Hydroida Hydridae Hydridae Cnidaria Hydrozoa Hydroida Hydridae Hydra Hydra sp.
