Assessing the Biological Health of Freshwater Ecosystems
Studying freshwater invertebrates since 1984
Aquatic Biology Associates is the longest established independent laboratory in western North America providing consulting services for aquatic invertebrates. By choice, Aquatic Biology Associates remains a small lab so we can give personal attention to all phases of your project. We help clarify project objectives and assess your data needs to deliver cost-effective quality results.
Robert Wisseman, Senior Scientist, is closely involved in developing national and state bioassessment protocols for evaluating the health and integrity of freshwater ecosystems. Mary Jo Wevers, CEO, has nearly five decades of experience working as an aquatic ecologist.
Our Technical Services
We are experts in freshwater macroinvertebrate identification, having analyzed tens of thousands of macroinvertebrate samples from streams, rivers, springs, wetlands, ponds, and lakes throughout western North America and Hawaii.
Our technical services include field sampling, endangered invertebrate species surveys, quantitative analysis of macroinvertebrate communities, and fish and bird food web analysis. We provide statistical data analysis in a variety of formats, interpretation of results to meet your needs, and prepared reports.
Our Experience
Aquatic Biology Associates has completed over one thousand projects from freshwater, terrestrial, and estuarine habitats in western North America, from the coast of the Arctic Ocean in Alaska and Canada south into Arizona.
Our projects have ranged from a single sample to over 1,000 samples in size. The U.S. EPA has retained us to consult on developing Biological Condition Gradient models for the Pacific Northwest and actively work on standard taxonomic effort issues in western North America through PNAMP and SAFIT.
