Sets of names used for analysis of algal samples in the USGS NAWQA, EPA NARS, and ANSP projects A common set of names is important for maximizing taxonomic consistency among analysts and comparability among datasets. Academy phycologists and collaborators, with support from the USGS, US EPA, and several state agencies, have developed and maintained a set of taxa names for use in agency sponsored projects and elsewhere. The current set of names (2011) has evolved from initial sets over the past 15-20 years. Many phycologists at several institutions have contributed to expanding and updating the names. Much of this work was supported by the USGS and documented in USGS NAWQA Workshop reports. The first set of names, or “taxonomic systems”, was developed in 1994. Names have been updated about every 3 years, typically as part of USGS NAWQA taxonomic workshops. More information on this dataset can be found in the Freshwater Metadatabase - BFE_73 (http://www.freshwatermetadata.eu/metadb/bf_mdb_view.php?entryID=BFE_73).
The ANSP Algae Image Database contains light micrograph images of diatom taxa from rivers throughout the USA. Many taxa are represented. There are multiple images of several to help represent within-taxon variability. The images were made primarily by ANSP Patrick Center Phycology Section staff as part of their routine analysis of algal samples. Purposes of the database are to: provide a set of reference images for ANSP algal analysts and collaborators to help them maintain consistency in taxonomic identifications help document names of taxa used in papers and reports by providing easy access to representative images make images available to other phycologists as a resource to help with identifications The set of images available here is not meant to be comprehensive or to be taxonomically definitive, but only to show representative specimens that can be used to supplement image resources in the published taxonomic literature. Read the documentation to learn more about the database and how to search for and view images. More images will be added on a regular basis. More information on this dataset can be found in the Freshwater Metadatabase - BFE_71 (http://www.freshwatermetadata.eu/metadb/bf_mdb_view.php?entryID=BFE_71).
