ABSTRACT: Traditional taxonomic identification keys are limited by new species introductions (intentional and unintentional), minor errors during publication, updated corrections for taxa and the fact that regional keys can’t cover all freshwater environments. Hardbound publication costs have sometimes restricted publication batches and access to important resources. Scientists have therefore relied on outdated, multiple keys to process samples from freshwater systems. Recently available, web-based key platforms provide flexibility for updates/corrections, expansion, inclusion of high-resolution images, and greater identification precision as additional taxonomic characters are developed. Under a project funded by the Electric Power Research Institute (EPRI), a collaborative effort was initiated to develop an open-access, web-based version of the seminal taxonomic key, Identification of Larval Fishes of the Great Lakes with Emphasis on the Lake Michigan Drainage (Auer, 1982). This updated open-access taxonomic resource includes larvae and eggs for fishes found within the Great Lakes region, as well as other freshwater environments. The key includes a total of 153 species from 25 families and is intended to assist taxonomists with an update and expanded resource for identifying this challenging life stage. The key was designed using Lucid3 software and is available at http://www.EPRIlarvalfishid.com. The key functions as a multi-access diagnostic tool as opposed to a traditional dichotomous key. This format allows the user to specify multiple features in any order. As known taxonomic features are entered, the list of possible individuals is narrowed and the tool identifies the species that have been eliminated along with an explanation as to why a species was eliminated. Thumbnail images are clickable and bring up a slide viewer to show multiple images and a larger view. The expanded view also provides metadata for the image including size, collection location, and author/copyright information. This presentation will include a brief description of key development and a step-by-step example demonstration of functionality.
