Great Lakes untamed. [videorecording] / by McIntyre Media,distributor.;
In winter, Great Lakes animals must deal with extreme temperatures. Divers explore the lakebed where a colossal ice sheet once ground into North America's bedrock, leaving five giant lakes when it melted. Each year the ice returns, challenging life. A powerful jet stream dip creates huge ice storms, the world's largest freshwater waves, and lake effect snow. Life has adapted. Otters frolic beneath Lake Huron's ice surface; giant freshwater cod sing and mate in the frigid waters; ravens outwit bald eagles and wolves, feeding on a deer; snow provides insulation for new-born black bears; the huge paws of a Canadian lynx help it move in deep snow; and the ultra-violet fur of flying squirrels deters predators. But some creatures are suffering due to the shorter, warmer winters. A rare wolverine is threatened by the warming climate and Great Lakes moose are declining in numbers. Ice and snow created North America's Great Lakes and its species have evolved to survive the harsh elements. In this warming world, the future of life in the Great Lakes will be shaped by one species - us.E.DVD.

Great Lakes untamed. [videorecording] / by McIntyre Media,distributor.;
The Great Lakes watershed is one of the world's largest freshwater ecosystems. 4,000 kilometers of coastline and are home to more than 3,500 plant and animal species. Each of the lakes' ecosystems has a unique inter-relationship with wildlife. Beavers and wolves jointly control the purity and flow of water into Lake Superior. Loons hunt fish in its clear waters. Lake Michigan has the world's largest freshwater sand dunes and the endangered piping plover. Scientists work to prevent Michigan River's invasive silver carp from entering this ecosystem. Lake Huron has one of the largest concentrations of shipwrecks in the world. Lake Erie is a bi-annual stopping point for millions of migrating birds. Pelee Island shores shelter the endangered blue racer snake. Niagara Falls, the most powerful waterfall in the world, drains the lake. Lake Ontario has the world's largest population of cormorants. Huge amounts of clean water enter it from the Ottawa River (the 6th of the Great Lakes). In the river's vast underwater cave system, millions of mussels filter the water. It will take 200 years for a drop of water to flow from the source of Lake Superior to the mouth of the St. Lawrence River, the largest estuary on Earth.E.DVD.

Great Lakes untamed. [videorecording] / by McIntyre Media,distributor.;
Animals of the Great Lakes cope with the most extreme, unpredictable temperature changes on Earth - from summer highs of 40 degrees to winter lows of minus 40. This transformation creates mysteries and marvels of evolution, life uniquely adapted to change. This land of wonder has weird and unique animal behaviours. The world's largest mass spawning occurs near Lake Michigan. Wolves fish for white suckerfish to feed their pups. Massasauga Rattlesnakes swim between Lake Huron's 30,000 islands to give birth to live young. A mother moose dives to the bottom of the lake to feed her calf. A thirty-year-old female salamander, the world's only 'photosynthetic vertebrate', makes an epic migration across snow near Lake Huron. In Lake Erie, colourful redside dace have evolved to catch insects in the air. Parasitic mussels imitate minnows to lure their prey and biologists use innovative new science to battle invasive sea lamprey. The adaptation of wildlife to successfully live and thrive in the Great Lakes watershed gives us hope about the future of the world's greatest and most important freshwater ecosystem.E.DVD.
