Description:
As part of a webinar round-table discussion of invasive species and ballast water research, Dr. Trebitz will be giving a short overview of the research that she and co-PIs Jack Kelly, Joel Hoffman, and Greg Peterson are conducting in this area. Key findings from the 2005-2007 sampling effort in the invasion-prone Duluth/Superior harbor are that 1) detecting NIS while they are still rare is inherently resource intensive; 2) designs need spatial coverage with variety of habitats and sampling gear, 3) complete counts and taxonomy are needed to fully evaluate performance, 4) optimizing sampling design requires system-specific knowledge, and 5) as-yet undetected NIS are likely out there because most systems have not been examined intensively. These findings are being validated and extended to additional taxonomic groups and additional systems via ongoing research .
