DIATOMS OF NORTH AMERICA: AN AUTHORITATIVE FLORA FOR TAXONOMISTS AND ECOLOGISTS

In 2010, the Diatoms of the United States was launched as an online flora documenting a handful of diatom genera and species. Since then, the website has grown to include over 150 genera and 860 species. It is a collaborative effort, with over 70 contributors (students, taxonomists, systematists) who provide content, with development and peer-review guided by an Editorial Review Board. Version 2 was completed in 2018, with design based on feedback from practitioners. The resource is gaining strength as the authoritative tool for consistent and correct diatom identification. Version 2 includes novel features such as filtering tools to select taxa by size and striae count. A list of names (and concept references) are included from the USGS BioData list. A revised "compare" section allows users to examine size and morphologic range of similar species. The project is a successful part of student training through the Ecology and Systematics of Diatoms field course at Iowa Lakeside Lab. For example, a number of taxon pages created by students have each received over 4000 visits. The website will next become the cornerstone for establishment of a taxonomic certification program for diatoms.
