Conservationists Hope to Reintroduce Lynx to the UK

The nations of the United Kingdom have a lot going for them. They’ve got history, spectacular landscapes, and a unicorn mascot. But they haven’t got lynx, and some find that fact unacceptable. A group of feline conservation experts hope to bring the vanished cats back to the UK within the next ten years.

The Eurasian lynx (Lynx lynx) has piercing eyes and black-tufted ears. At about the size and weight of a large terrier, L. lynx is too small to be considered a big cat, but it’s certainly wild, hunting deer and other mid-size mammals for food. Lynx are solitary animals, which means that each adult needs its own territory. Many, many years ago, as human encroachment on lynx habitat increased throughout Europe, populations dwindled and some disappeared. The last time a lynx was seen in England was around the year 700. Which means, according to members of the Lynx UK Trust, it’s time to restore the missing lynx.

Species introduction programs have been around for a while, as people attempt to restore balance to damaged ecosystems. But with so many factors at play, early reintroduction efforts were more likely to fail than succeed. A lot of animals have died because well-meaning conservationists failed to account for unpredictable climate or new human threats.

Each failure is a lesson however, and today’s reintroduction programs are typically more sophisticated and more successful. About a dozen species, from bison to butterflies, have been re-established in the UK alone.

Members of the UK Lynx Trust have good reason to think a reintroduction program could work: It’s already working elsewhere. A captive breeding-and-release program in Spain has tripled lynx populations on the Iberian Peninsula. In 2014 and 2015, 124 captive-bred cats were released into the wild. Less than a year later, the lynx population numbered 400. Programs in Germany are off to a similarly promising start.

There are some hitches, of course. For one thing, the Spanish program focused on the Iberian lynx, not the Eurasian. The two species are quite similar, but they aren’t the same. For another, some UK citizens are less than thrilled with the idea of predators being released into nearby forests. "They're reputed to do a lot of their hunting within a 200–250m area surrounding woodland, and there is an awful lot of grassland grazed by sheep surrounding woodland," National Sheep Association chief executive Phil Stocker told the BBC.

Conservationists insist that the cats want deer, not livestock, and that they would be reluctant to leave the woods. “You will never see Eurasian lynx running across an open field," feline expert Paul O’Donoghue told the BBC.

The Lynx UK Trust is now in the process of identifying potential release sites. Once they’ve found those, the next step will be consulting experts—and the locals—to check if the plan is viable.

This High-Tech Material Can Change Shape Like an Octopus

Octopuses can do some pretty amazing things with their skin, like “see” light, resist the pull of their own sticky suction cups, and blend in seamlessly with their surroundings. That last part now has the U.S. Army interested, as Co.Design reports. The military branch’s research office has funded the development a new type of morphing material that works like an octopus’s dynamic skin.

The skin of an octopus is covered in small, muscular bumps called papillae that allow them to change textures in a fraction of a second. Using this mechanism, octopuses can mimic coral, rocks, and even other animals. The new government-funded research—conducted by scientists at Cornell University—produced a device that works using a similar principle.

“Technologies that use stretchable materials are increasingly important, yet we are unable to control how they stretch with much more sophistication than inflating balloons,” the scientists write in their study, recently published in the journal Science. “Nature, however, demonstrates remarkable control of stretchable surfaces.”

The membrane of the stretchy, silicone material lays flat most of the time, but when it’s inflated with air, it can morph to form almost any 3D shape. So far, the technology has been used to imitate rocks and plants.

You can see the synthetic skin transform from a two-dimensional pad to 3D models of objects in the video below:

It’s easy to see how this feature could be used in military gear. A soldier’s suit made from material like this could theoretically provide custom camouflage for any environment in an instant. Like a lot of military technology, it could also be useful in civilian life down the road. Co.Design writer Jesus Diaz brings up examples like buttons that appear on a car's dashboard only when you need them, or a mixing bowl that rises from the surface of the kitchen counter while you're cooking.

Even if we can mimic the camouflage capabilities of cephalopods, though, other impressive superpowers, like controlling thousands of powerful suction cups or squeezing through spaces the size of a cherry tomato, are still the sole domain of the octopus. For now.

According to the ASPCA, 3.3 million dogs enter shelters each year in the United States. Although that number has gone down since 2011 (from 3.9 million) there are still millions of dogs waiting in shelters for a forever home. October is Adopt a Shelter Dog Month; here are 25 benefits of adopting a shelter dog.
