November 1999 NAWQA Diatom Taxonomy Harmonization Workshop

In a continuing effort to maintain taxonomic consistency between institutions, theAcademy of Natural Sciences (ANS) hosted a meeting with scientists from the Patrick Center forEnvironmental Research (PCER) Phycology Section, and Michigan State University (MSU).This is the second meeting in an ongoing series of consultations among scientists analyzing algalsamples for the USGS National Water Quality Assessment Program (NAWQA). In attendancewere senior scientists: Dr. Donald Charles (PCER) and Dr. Jan Stevenson (MSU); database andmanagement experts: Pat Cotter (PCER), Frank Acker (PCER), and Candia Knowles (PCER);and taxonomic specialists: Todd Clason (PCER), Lont Marr (PCER) and Kalina Manoylova(MSU).

One of the main products of the May 1999 meeting was a workshop report (ANS ReportNo. 99-14) that included a list of 500 names and authorities representing all diatom taxaobserved at >1% abundance in NAWQA study units analyzed by phycologists at the PCER andUniversity of Louisville (Jan Stevenson’s lab has since moved to MSU). This list also provided arating system to indicate the level of certainty regarding individual literature-based taxadesignations. The primary goal of the November workshop was to complete a final inventory ofall the taxa found in NAWQA 1994-start samples (collected in 1995-1998). The list includes1,131 taxa names, along with the master NADED ID numbers, and specific image citations(Appendix 1). While the list is immediately useful to taxonomists at the PCER and MSU, it isalso indicative of the large volume of synthesized data from both institutions that is nowaccessible through the PCER Phycology Section NADED database system. This information willbe a comprehensive resource for all NAWQA biologists having specific questions regardingparticular diatom taxa. It will also be a foundation for maintaining consistency amongtaxonomists. Finally, the ability to create specific taxonomic lists through database queries willgreatly facilitate discussions concerning taxonomic transfers over time, which will be animportant topic during the May 2000 workshop.

Another important accomplishment of the November meeting was the direct microscopicexamination of type material. Consultation of type material helps solidify taxonomic conceptsthrough examination of diagnostic features that are difficult to observe in photographs ordrawings. By performing this examination as a group, analysts could agree on which features aremost important and should be emphasized to achieve consistency. The ANS Diatom Herbariumis the largest in North America, and of prime importance in maintaining the quality of analysisoffered by PCER and MSU diatomists.

During the workshop, taxonomic analysts also examined unknown diatoms. “Unknowntaxa” are specimens either not yet described in the literature, or not yet designated with a specificreference by the analyst. Group examination of unknown material is crucial to avoid multipleunknown designations for single unknown species, and to solve taxonomic issues. Although itwas not a prime goal of the workshop, several problems concerning unknown taxa were rectifiedand subsequently amended in the database.


Analysts captured digital images of many of the specimens observed during theworkshop. These were added to the ANS algae image database for future reference. Notabletaxa are shown in Figure 1. The ANS has a growing number of digitized diatom images that arenow easily accessible by taxonomists from both the ANS and MSU via a web-based application.Capturing and databasing images at the ANS has been greatly expedited through direct entrywith Visual Basic database interfaces. This new image acquisition process minimizes time takenaway from slide analysis, and image data are immediately useful. Sharing of digitized imagespromotes taxonomic consistency and augments existing approaches for confronting taxonomicissues.

As the May 2000 workshop approaches, analysts will greatly benefit from the foundationlaid during previous meetings.
