When HAB events require restrictions on fisheries, recreation, and drinking water uses of inland water bodies significant economic consequences result. Unfortunately, the magnitude, frequency, and duration of HABs in inland waters are poorly understood across spatiotemporal scales and differentially engaged among states, tribes, and territories. Harmful algal bloom impacts are not as predictable as those from conventional chemical contaminants, for which water quality assessment and management programs were primarily developed, because interactions among multiple natural and anthropogenic factors determine the likelihood and severity to which a HAB will occur in a specific water body. These forcing factors can also affect toxin production. Beyond site-specific water quality degradation caused di...

In other words, we don't always know exactly what these species indicate, and even when stress-response relationships are documented, we rarely know how the biotic signal is confounded by biogeography or local ecological circumstances. Recent data from a large scale study of Great Lakes coastal wetlands allows us to quantify stress-response relationships of birds, amphibians, invertebrates, fishes, diatoms, and wetland plants. As expected, different taxa respond to different stressors, and the nature of these responses is not uniform among species within the same taxonomic group. This finding implies that comprehensive environmental indicators based on species richness or related metrics are misleading or, at best, difficult to interpret. We propose an alternative approach that incorporates explicit stress or response relationships of species or ecological guilds. This maximum likelihood method is flexible and can generate multi-species metrics that incorporate information from a variety of taxonomic groups.

Tests took place at the GSI Land-Based Research, Development, Testing and Evaluation (RDTE) Facility located in the Duluth-Superior Harbor (DSH) of Lake Superior (Superior, Wisconsin, USA) during September and October of 2013. Test objectives were: • To provide reliable information on FS operational and biological performance in freshwater under controlled conditions, and to support limited performance comparisons across FSs; • To explore any trade-offs between operational and biological performance endpoints; and • To support FS, and thus ballast water management system (BWMS), freshwater performance improvements. The eight commercially available FS units GSI tested represented a range of filtering technologies and nominal pore sizes. Tests took place over a five week period, ...
