Meet the Marbled Crayfish
There’s an invasive species in Ontario that has wildlife experts on high alert. It reproduces asexually and can lay 500 eggs at a time. Meet the marbled crayfish.
The marbled crayfish was popular in the aquarium trade as both a pet and as fish food. Since 2022, it’s been listed as a prohibited species under Ontario’s Invasive Species Act, meaning it could not be bought, sold, traded, or kept in home aquarium. But that hasn’t stopped the marbled crayfish from invading Ontario’s waterways.
For more than 30 years, Ontario’s Invading Species Awareness Program has been on the frontlines in the fight against invasive species. Learn how they’re tackling this new threat to Ontario’s ecosystems.
Lake Superior’s Warming Waters
When describing Lake Superior, it’s not uncommon to use adjectives such as HUGE, DEEP, and most popular COLD. But climate change brings a surprisingly new descriptor to the list… WARM!
As daily average temperatures rise around the globe, the world’s largest lakes are feeling the effects of climate change. Here in the United States, Lake Superior – which is the largest, deepest, and coldest Great Lake – is among the fastest warming of the world’s large lakes. Join us as we investigate the effects and implications of our changing climate on Lake Superior.
In this segment, Filmmaker John Shepard of Hamline University’s Center for Global Environmental Education talks about his documentary A Sea Change for Superior: The Warming of the World’s Largest Lake. His film examines the vulnerability of Lake Superior and how the warming of its’ water impacts residents, scientists, and the ecology of the lake and surrounding ecosystems. Most notably resulting in less ice coverage in winter, extreme weather, and hazardous algal blooms.
