Tracking the Pack

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, 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. (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, 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 The lanyard series is a grand collection of coordinating Travertine mosaics and listellos.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, 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.All realtimelocationsystem comes with 5 Years Local Agent Warranty ! 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.Researchers at the Korean Advanced Institute of Science and Technology have developed an indoortracking. 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. 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,We offers custom moulds parts in as fast as 1 day. 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.All our fridgemagnet are vacuum formed using food safe plastic.

The social network and photo sharing mobile app has been automatically geotagging users' photos even when they have completely disabled location services.

The bug was discovered by security researcher and hacker Jeffrey Paul who found that Path had geotagged a photo he published from his phone even though his location services had been disabled.

It turns out that the social network had taken the metadata from the photo (information embedded within the photo file that specifies the time it was taken, the location, the device it was taken on etc) and used it to geotag the post.

EXIF data can be removed from images but it's a bit of a pain, especially considering that users' have already asked for their location information not to be published.

The discovery comes about a year after Path was caught publishing users' entire address books and just days after Path paid an $800,000 fine for collecting information on its underage users without parental consent.
