As Great Lakes lose ice, a UWindsor researcher makes the consequences visible — and wins an international prize for it

As climate change strips ice from the Great Lakes, something less visible is also changing: the underwater world of light that microscopic life depends on.  

When ice recedes, wind and water stir sediment, clouding the water and blocking the sunlight that drives photosynthesis at the base of the food web. What looks like a simple seasonal shift is, in scientific terms, a restructuring of habitat. 

UWindsor research shows surprising implications in fish farming

Some farmed fish are snubbing commercial fish food pellets in favour of naturally and freely available microscopic organisms and invertebrates.   

That is according to PhD candidate Dennis Otieno’s study which showed farmed tilapia in net-pen cages in Kenya were not significantly consuming the provisioned commercial fish feed – one of the highest costs of production. 

Local Tags to Global Impact: UWindsor Sharks in Landmark Study

Nigel Hussey’s shark research takes him around the world where he sees first-hand the critical nature of conservation work.  

Now, as part of a massive international study looking at the movement of threatened, large marine animals, he says we can see the harsh reality of global marine conservation.  

“The study shows we’re not protecting habitat for key functions for these species,” he says.
