The Eurasian Lynx entered North America across the Bering Land Bridge about 2.5 million years ago, in the first of two waves. Glaciers waxed and waned, alternately blocking and opening Beringia, as well as migration paths down to what would become the U.S. border and Canadian province areas, a classic example of how one species gets separated by changing land and sea features, the two groups then evolving in different directions, until representatives of one group can no longer mate, thus resulting in two species. The second wave, coming with melting of northern glaciers evolved into the Canadian Lynx.

Big cats such as panthers, tigers and lions are often featured in popular media. With their great strength, size, and seemingly endless confidence, these felines command attention. There are other members of the Felidae family however that go more unnoticed.
Bobcats (Lynx rufus), Canada lynx (Lynx canadensis), Eurasian lynx (Lynx lynx), and the Iberian lynx (Lynx pardinus), although dispersed throughout most of the world, appear to share a similar ancestor, Lynx issiodorensis or Issoire lynx, which went extinct more than 12,000 years ago. » Continue Reading.
In the northern forest, a big gray cat crouches silently in a dense thicket of fir along a snowshoe hare run. Its pointed ears, topped with long tufts of black hair, twitch as it listens intently. The cat’s face is framed by a fur ruff and its yellow-green eyes are alert for movement. Suddenly, the lynx pounces, killing its prey with one quick bite to the neck. As it pads away with the hare, the lynx’s broad furry paws act like snowshoes, supporting it in the deep snow. Its short tail is tipped with black.
The Canada lynx, once eliminated from most of New England by forest clearing and unsustainable hunting and trapping, is making a comeback. Though still listed as a federally threatened species, there is an expanding breeding population in northern and western Maine, smaller numbers of lynx in northern New Hampshire, and intermittently, cats have been found in Vermont. » Continue Reading.
A fellow carnivore scientist once showed Cristina Eisenberg the skeleton of an animal and asked her to identify it. Looking at the large hindquarters and feet, she guessed snowshoe hare. Told she guessed wrong, she took a closer look.
“I looked at the skull, and it was a lynx,” said Eisenberg, a scientist with Earthwatch Institute, an international environmental organization.
Eisenberg might be forgiven for her initial mistake: the Canada lynx and snowshoe hare have some anatomical similarities. “They have very big, soft feet that don’t punch through the snow,” she said. “Their feet are like snowshoes.” » Continue Reading.
