Their isolation arises from the geography: they live in a complex landscape of fjords on the very edge of their range on the southern tip of Greenland, well below the Arctic circle, with nowhere to go. Unlike their cousins, the Southeast Greenland polar bears were found to be homebodies, seldom straying far to hunt. "We know that this population has been living separately from other polar bear populations for at least several hundred years." Thought to number a few hundred individuals, "they are the most genetically isolated population of polar bears anywhere on the planet," said co-author Beth Shapiro, a geneticist at the University of California, Santa Cruz and investigator at the Howard Hughes Medical Institute, in a statement. ![]() The team tagged the bears with satellite tracking devices and collected genetic samples by either capturing bears or firing biopsy darts into their rumps. Fuel depots had to be staged along the route in advance down the coastline, creating a hopskotch-like commute to work. They then began their own field work, which lasted from 2015 to 2021, in a harsh region that was long understudied because of its unpredictable weather, heavy snowfall and jagged mountains.Įach year, the team would spend one month in springtime, staying in the nearest settlement Kuummiit, which is a two-hour helicopter ride from where the bears live. Laidre and colleagues first spent two years interviewing Inuit subsistence hunters who provided input and ecological knowledge, including harvest samples for analysis. "I think that bears in a place like this can teach us a lot about where those places might be." "One of the big questions is where in the Arctic will polar bears be able to hang on, what we call 'persist,'" first author Kristin Laidre, a polar scientist at the University of Washington and Greenland Institute of Natural Resources told AFP. Their findings, described in the journal Science on Thursday, open up the tantalizing possibility that at least some pockets of the species might be able to survive further into this century when Arctic sea ice is expected to disappear completely during the summer months. What is your favorite panorama photography tip? Let us know in the comments below.Polar bears face an existential threat from the rapid decline of Arctic sea ice, which they rely on as platforms to hunt seals.īut in a new study, scientists have identified an isolated subpopulation of polar bears in Southeast Greenland that instead make use of freshwater ice pouring into the ocean from the region's glaciers, suggesting this particular habitat is less susceptible than others to climate change. And towards the end of the video, Mackie also takes you through a convenient way to stitch the panorama using Lightroom. Each of the orientations has its own set of advantages. As Mackie demonstrates in the video, you can easily do this by using manual exposure mode and manual focus respectively.įurther in the video, you’ll also get to know when to take vertical panorama versus horizontal panorama. Similarly, make sure you lock the focus to one desired distance. You should also ensure that the camera does not change its exposure settings every time you press the shutter. If your camera has an in-built level gauge, you can use that too. You can see in the video how Mackie ensures proper balance by using a bubble spirit level. Make sure to balance your camera throughout the panning range this is very important, otherwise, you will end up cropping a huge portion of your image when aligning your images. Otherwise, simply follow the tips that Mackie shares in the video, and the results will still come out looking brilliant.Ī basic check you need to make is to ensure that your tripod and camera are well balanced. If you are really serious and have the time, you can use the nodal-point method. He shows how you can take beautiful panorama photographs simply using your camera and a tripod. The process that Mackie shares in the video is quite simple. If you are looking to getting started with photographing panoramas or improve your skill, check out the video below: photographer Tom Mackie explains everything you need to know about panoramic photography. You do this by taking multiple shots across the scene and later merging them in post-production. ![]() Panorama photography is the best way to captures wide-angle views.
