Ever since the 1950s, Canadians have been applying 5-7 million tonnes of salt every winter to make our roads, parking lots, driveways, and other public areas safer for cars and pedestrians. When the snow begins to melt and the rain falls, all that salt leaches into the soil or washes into waterways and accumulates in […]

Amphibians – like other cold-blooded animals – endure the harshest winter conditions without an internal source of body heat. They have evolved some extraordinary mechanisms to survive. Amphibians brumate over the winter months. Similar to hibernation, brumating animals slow their metabolism and allow their body temperature to drop. Although the Biosphere’s amphibians all face similar […]

It is impossible to overstate the importance of phosphorus in the aquatic food web, as it forms the foundation of life in these waters. Everything from the tiniest phytoplankton all the way up to top predators like lake trout and loons rely on phosphorus. You may have heard the terms “nutrient-rich” and “nutrient-poor”. In the […]
Clusters of a sticky zooplankton (Holopedium glacialis) are crowding out a previously abundant and ecologically important species (Daphnia spp.) in many Ontario inland lakes. The name for this phenomenon is “jellification,” and it’s an apt description for the masses of clear jelly spheres afloat in many provincial waters. To be clear, Holopedium is not an […]

If you have been outside recently exploring the trails in your area or just getting out in your yard, you have probably encountered numerous caterpillars and their handiwork. These are LDD caterpillars, also called gypsy moth caterpillars. The LDD moth (whose acronym arises from its Latin name Lymantria dispar dispar) originates in Asia and Europe. […]
With air temperatures on the rise, it won’t be long before maple sap isn’t the only thing running. Each spring, as the ice on our lakes and rivers goes out, a number of fish species begin their spawning runs. Many people in the region are familiar with the spawning runs of rainbow smelt (Osmerus mordax) […]
Whether you skate on it, ice fish through it, or you simply take in its sights and sounds, ice is worth celebrating. For those who live in the Georgian Bay Biosphere, ice cover is important to our economy, recreation, as well as to native species and their habitats. But what happens if we start to […]
