Aquatic Taxonomy Services

Aquatic organisms are used as indicators in biomonitoring and ecological assessment studies. GLEC has the professional staff and laboratory resources to sample, enumerate and identify, and photograph periphyton, phytoplankton, zooplankton, macroinvertebrates, and fish. GLEC staff have been collecting and identifying aquatic organisms for over 25 years. GLEC taxonomists have processed over 6,000 benthic macroinvertebrate samples and are certified by the Society for Freshwater Sciences. GLEC fish taxonomists are specialists in identifying North American freshwater fish species. GLEC’s two algal taxonomists hold doctorates in algal taxonomy and ecology and a combined 30 years of algal identificaton experience. Our Traverse City, MI laboratory has a full complement of precision analysis equipment supported by a comprehensive taxonomic library and reference specimens and images.
