Carrie J. Blakeslee, Stephanie Sweet, Heather S. Galbraith, Dale C. Honeyfield
2015, Journal of Great Lakes Research (41) 516-519
Thiamine (vitamin B1) deficiency in the Great Lakes has been attributed to elevated levels of thiaminase I enzyme activity in invasive prey species; however, few studies have investigated thiaminase activity in native prey species. Some of the highest levels of thiaminase activity have been measured in invasive dreissenid mussels with...
