Algae are an important part of a properly functioning natural aquatic system, but when algae become abundant, water uses and habitat are often impaired. Toxicity of algae has become a “hot button” issue, and other water quality implications and aesthetic considerations remain prominent issues. All algae were not created equal, however, and proper collection and identification are essential to selecting a management strategy. This workshop is intended to provide information on how to collect and recognize common genera within major groups of algae, with emphasis on taxonomic detail and identification approaches. Participants are encouraged to bring any algae samples with which they would like identification help. The workshop also covers basic algal ecology and the methods used to control algae, but with only 8 hours, we can only introduce participants to issues and options.

The workshop is taught by Drs. Ken Wagner, Ann St. Amand, Andy Chapman and Barry Rosen, all experienced algal taxonomists and ecologists working in applied fields. Collectively they have many years of experience assessing algal problems, evaluating impacts and causes of algal nuisances, and developing algal management programs.

Presenters

Ann St. Amand (co-chair) holds a Ph.D. in Aquatic Ecology from the University of Notre Dame. She has 37 years of experience identifying and enumerating over 45,000 algal samples from all over North America. Her company uses a unique proprietary mounting method, and custom software containing information on nearly 34,000 different aquatic organisms. She is particularly interested in rapid assessment of recreational and drinking waters for human and environmental health.

Ken Wagner (co-chair) holds a B.A. in Environmental Biology from Dartmouth College and M.S. and Ph.D. degrees in Natural Resource Management from Cornell University. He has taught an algal workshop in association with the North American Lake Management Society for 25 years, working cooperatively with expert phycologists and ecologists.

Barry Rosen has a B.S. in Botany from University of Connecticut, Storrs, M.A. in Biology from St. Cloud State University, Minnesota, and Ph. D. in Biology from Bowling Green State University, Bowling Green, Ohio. He has worked in algae in freshwater ecosystems for the past 40 years. He has been affiliated with several universities, the private sector, state and federal government and most recently Florida Gulf Coast University. He has lived in several states including Virginia, Nebraska, Florida, Oregon, Vermont, Michigan, North Carolina and now Florida, working on a HABs nationwide.

Andrew Chapman has been a phycologist with GreenWater Laboratories since its inception in 2001. Received B.S. in Biology from Susquehanna University in 1990 and a M.S. in Botany from the University of Oklahoma in 1993. Masters research was on freshwater dinoflagellates. Since moving to Florida in 1993 has been particularly interested in the ecology and taxonomy of potentially toxic cyanobacteria.
