Corixids, or water boatmen, are wetland insects with oars for legs and wings that can carry them kilometers from their homes when it's time to migrate.
Stephen Srayko, a PhD in biology candidate at the University of Saskatchewan, has been studying that migration for years. He watches as the corixids lift off from marshes and land on the shores of the North and South Saskatchewan Rivers in swarms during the fall.
There white sucker, longnose sucker, and goldeye fish feed on the massive influx of food. In turn, they provide sustenance to the rivers' game fish.
Srayko thinks the corixids provide a near-invisible link between wetlands and the nearby rivers. They're one more reason why conserving wetlands helps a broader eco-system.
How did Canadian musician David Archibald spend his summer vacation? He did a musical tour of 31 Ontario provincial parks (and worked in an eight-day voyager canoe trip for R and R).
His campground concerts were aimed at kids and families and celebrated the history of the parks. But, with his often playful songs, he also educated his audience about the ecology and fragile nature of the habitats within park boundaries.
Ducks Unlimited Canada does its own educational outreach through our Wetlands Centres of Excellence and Wetland Heroes programs.
But this episode, we’re focussing on Archibald’s education through music.
Archibald has been interpreting natural spaces with his music for 29 years when Bon Echo Provincial Park hired him to celebrate the petroglyph-famous campground in song.
He has written for and performed on Sesame Street in New York and CBC's Mr. Dressup.
But he’s also a music producer (he gave Avril Lavigne her first shot at a studio microphone) and is currently the musical director for a show about Stompin’ Tom Connors.
That’s where we caught up with him for this episode.
