Fourteen teachers from throughout the Great Lakes basin embarked on the learning opportunity of a lifetime this month, taking part in a week-long workshop aboard the U.S. Environmental Protection Agency’s research vessel Lake Guardian. They explored first-hand Lake Huron’s geology, limnology (freshwater science), and ecology, with a special focus on the food web as it relates to Huron’s fisheries. 
 
The teachers worked side-by-side with scientists learning a great deal about what comprises research on the Great Lakes. They assisted with the collection of planktonic and benthic organisms, as well as gathering water quality data. They also explored Great Lakes curriculum and discussed how to integrate this information in their classrooms. You can see visit their blog and learn more at cossegreatlakes.net. This program is offered annually by EPA’s Great Lakes National Program Office and the Great Lakes Sea Grant Network. If you are an educator, consider applying next year for the cruise on Lake Ontario!

Join the Invasive Crayfish Collaborative for an exciting webinar featuring Dr. Chris Taylor from the Illinois Natural History Survey who will provide an overview of midwestern crayfish habitat requirements, feeding, reproductive biology, and life-history.Crayfishes in the Midwest occupy almost every type of aquatic and semi-aquatic habitat in the region. They function as critically important components of those ecosystems and in many cases represent a majority of invertebrate biomass. As “keystone” species, understanding their biology and roles in ecosystems is critically important. Register for the webinar at InvasiveCrayfish.org/events1 Or the link in bio.
