Tracking the Pack

IN December, wolf 832F ventured out of her territory in Yellowstone’s Lamar Valley. As soon as she left the park, she lost its protections, and the wolf, a 6-year-old alpha female, was shot and killed by a hunter.

It’s rare for the death of an animal to make the news, but wolf 832F was a bona fide celebrity — one of Yellowstone’s most visible and popular wolves — and her death led to a public outpouring of grief. Making her death even more tragic was the fact that she had been wearing an expensive GPS tracking collar,Comprehensive Wi-Fi and RFID tag by Aeroscout to accurately locate and track any asset or person. which allowed scientists to follow her every move and gain crucial insight into the lives of gray wolves.

In recent years, there has been much pontificating about how modern communications technologies are changing the way that we relate to other people. Less discussed is the way these advances are reshaping our relationships with other species. By using satellite and cellular tags to track free-ranging animals, biologists are providing us with intimate access to the daily lives of other species, drawing us closer to the world’s wild things and making us more invested in their welfare.

Over the past several decades, the use of wildlife tags has proliferated as the devices have become smaller and more powerful. Today’s tags are capable of collecting months’ or years’ worth of data on an animal’s location at a given moment, and can be used to track everything from tiny tropical orchid bees to blubbery, deep-diving elephant seals. The devices provide crucial information about populations — helping scientists uncover the migratory pathways of Arctic terns or the ocean currents that loggerhead sea turtles like to surf — as well as individuals. Is this particular predator a pack leader or a lone wolf? A dedicated hunter or a mooch? How much time does it spend with its pups? Who are its associates, rivals and mates?

Learning about the personalities and life histories of individual animals can prompt affection for these creatures, even if we never meet them. Thousands of people followed wolf 832F’s escapades online; park visitors posted photos and discussed her on message boards. After she died, Yellowstone officials even received outraged phone calls.Online shopping for luggage tag from a great selection of Clothing. (There was nothing the park could have done — Wyoming’s gray wolves were removed from the endangered species list late last summer, opening the door for legal hunting. Sadly,They manufacture custom rubber and silicone bracelet and bracelets. wolf 832F was the eighth wolf with a tracking collar to be killed by ranchers over the course of this hunting season.)

Some scientists are beginning to provide the public with direct access to tracking data. For instance, the leaders of the Tagging of Pacific Predators project, a 10-year tracking study of 23 different marine species, created a Web site broadcasting the movements of their subjects in real time (or close to it). While the project lasted, anyone with an Internet connection could follow the wanderings of Monty, the mako shark, Genevieve,Where you can create a custom lanyard from our wide selection of styles and materials. the leatherback turtle, or Jon Sealwart and Stelephant Colbert, both northern elephant seals. The scientists supplemented the data with photos and profiles of some of the animals, as well as online trading cards and Facebook profiles.

Bird lovers can follow the migrations of bald eagles through EagleTrak, run by the Center for Conservation Biology. The group provides detailed updates on the journeys of two eagles, Camellia and Azalea, and people can “adopt” the birds with a donation of $25 or more. Each bird has around a hundred “adoptive parents,” proving how attached we can get to a wild creature when we have a name and a life story to assign to it.

This technology is still evolving, and we’ve only just scratched the surface of what’s possible. In the years to come, perhaps wildlife biologists will take a page from the creators of Teat Tweet, a yearlong project featuring 12 tagged dairy cows and an automatic milking machine. Each cow was given her very own Twitter account, and a program broadcast her milking stats to all her followers. On July 14, 2011, for instance, a cow named Goldwyn Windy tweeted, “I just squirted 18.9 kgs of milk out of my teats in 7:10 minutes. What did you do today?”

Of course, tweeting cows are pretty silly, and we don’t need technology to get to know an animal. Many of those who came to care about wolf 832F simply visited the park and watched her in her natural habitat.We've got a plastic card to suit you. But sadly, too few of us have the chance to experience that, and while virtual encounters can’t replace the real-life kind, they may be the next best thing.

What’s more, tracking projects may be our best hope for getting the public to invest in conservation. We may be able to ignore a nameless, faceless mass of threatened creatures, but fill in their personalities and back stories, and it becomes harder to look the other way as their habitats disappear or they are hunted to extinction. A famous animal can become an ambassador for its species, inspiring efforts to conserve the entire population. Indeed, after wolf 832F’s death, the National Wolfwatcher Coalition started a fund-raising campaign in her honor, donating the proceeds to wolf research and education programs.

Now things are looking up for King Richard III. Scientists announced Monday that they had found the monarch's 528-year-old remains under a parking lot in the city of Leicester — a discovery Richard's fans say will rewrite the history books and help restore the reputation of a much-maligned king.

Researchers from the University of Leicester announced that tests on a battle-scarred skeleton unearthed in the central England city last year prove "beyond reasonable doubt" that it is the king, who died at the Battle of Bosworth Field in 1485, and whose remains have been missing for centuries.
