Information for contributors

As the online taxonomic and ecological resource grows, we are seeking new contributors to submit taxon pages. This project depends on the involvement of many people working on the diverse diatom flora of streams, rivers, wetlands, lakes, springs, soils and estuaries of the country. We hope, eventually, to include the thousands, or tens of...  Read More >

Planning for the future of Diatoms of the United States

In September (16-20), members of the Editorial Review Board, Environmental Protection Agency representatives and web designers will gather at INSTAAR, University of Colorado, to discuss planning for the future of the project. Many of our users (you) have responded to requests for feedback on both the content and features of the website. Some of...  Read More >

Prioritization of taxa for funding

We aim to provide taxon records, that is, to “populate” the online flora for diatoms with additional species pages. Since our launch in 2010, we have increased both the number of expert contributors and taxa, and our goal is to reach 3000 (or more) species pages to document the diatom flora of North America. It is also important to the success...  Read More >

The Glossary Project: Illustrated terms, with style

Rob Kimmich, a new Contributor to Diatoms of the United States, and I have been revising the project glossary over the last couple of months. We have edited existing definitions, added new definitions, created illustrations for terms, and provided hyperlinks to direct you to related terms. For example, you can click on frustule, and follow the...  Read More >

Visualizing Diatom Evolution

There is currently a disconnect between the system of diatom names, or taxonomy, and the evolutionary relationships of diatoms, or phylogenies. Teo Nakov, a doctoral candidate at University of Texas, Austin, is working to change that. Teo has launched a website to serve as a repository for diatom phylogenies, expressed as evolutionary trees.

The...  Read More >

Summer Field Course on Diatoms

ECOLOGY AND SYSTEMATICS OF DIATOMS
19 May – 13 June 2014
Instructors: Sarah Spaulding, Mark Edlund

This course, now in its 51st year, will introduce students to field and laboratory study of freshwater diatoms. We will visit diverse aquatic habitats of the Upper Midwest to make live and fossil collections of most freshwater diatom genera....  Read More >

E.F. Stoermer Diatom Scholarship

The Eugene F. Stoermer Diatom Scholarship was established by Gene’s family, friends, and colleagues following his passing in 2012. Over $6,500 of the endowed scholarship was raised by students and colleagues at the 2013 North American Diatom Symposium held in Bar Harbor, Maine. A single $500 scholarship will be awarded annually to an advanced...  Read More >

How are striae measured in centric diatoms?

The number of striae, or other rotational elements of centric diatoms, such as fascicles, costae, spines, rimoportulae, fultoportulae and other valve features are often repeated on a diatom valve. This type of symmetry is called rotational symmetry (Theriot 1988). The number and position of a rotational element may be an important morphologic...  Read More >
