On the North North Coast, Norway, an unknown cave sat down to humans for more than 75,000 years. This distant field in the European Arctic is given the Hadithists specialists a glimpse of ancient animal societies that described this region as a home. Old residue with at least 46 species of animals helps researchers to re-examine the ecosystem in the last ice age-while it was a warning to the future. Their results were detailed in a study published on August 4 in The facts of the National Academy of Sciences ((pnas).
During the 1990s, Norway witnessed an increase in industrial mining projects. Many of these workers are required to build extensive tunnel systems in Mount Rocky. In 1991, efforts to excavate the local company unexpectedly revealed the deposit of 42.6 feet in the ARNE Ovamgrotta Cave. While Arne Ovamgrotta and the largest storsteinhola cave system are not naturally accessible to mining, they have been available to animals about 71,000 years ago, during the last iceberg.
ARNE Ovamgrotta has been largely unaccreditated for nearly 30 years until 2021. A research team led by the University of Oslo and Bournemouth University organized a drilling survey. They were hoping that any potential discoveries will help experts to develop the distant environmental past context in the region.
“We have very little evidence of what the Arctic life was in this period due to the lack of a preserved not exceeding 10,000 years.” A statement in a statement.
After months of drilling, BoesSenkool and the collaborators ultimately classified the oldest residue of the known animal in the region. It seems that humans have not visited the Ovamagrotta until the 1990s, but it is clear that a wide range of other types used the cave – often the place of the final comfort. In total, the researchers emphasized bones of 46 different types of mammals, birds and fish: ancient polar bears, Atlantic misery, cod, pronunciation, and bow whales .. Even the team discovered the remains of Collared boatsThe species have now become extinct throughout Europe and have not been documented before in the Scandinavian countries.
This diversity in animals indicates that the cave and coastal areas surrounding mostly have been dissolved 75,000 years ago. While it is still technically in the Ice Age at the time, The period was noticeably warmer. The temperatures were high enough to dissolve near icebergs and provide an animal home including migratory reindeer. The team close to Harbour Porpoise Bones by the team indicates that any sea ice was able to form it was seasons at best, because water mammals usually avoid them. Fresh water fish also revealed that tandra should guarantee rivers and lakes.
However, these residents ultimately cannot adapt as needed. The warming climate in the region was not 75,000 years ago the end of the ice age. Instead, the temperatures actually decreased again, leading to another era of ice water and ice boards. The entire animal communities died later when they were unable to migrate to various environmental systems. The additional DNA test did not appear any of the documented species with their cooler world.
“This highlights how the cold air -conditioned species are struggling to adapt to the main climate events. This is directly related to the challenges they face in the Arctic today with high temperatures at a rapid pace,” the first author of the study, Sam Walker.
Walker also warned the current animals that live in the region with “more broken” habitats that make survival more challenging. Meanwhile, BoesSENKool highlighted the outstanding details.
“It is also important to note that this was a turning more cold [climate]She said: “It is not a period of warming that we face today, and these are cold -conditioned types – so if they struggle to deal with more cold periods in the past, it will be difficult for these types to adapt to the warming climate.
By continuing to study these bones and similar discoveries, Walker and his colleagues hope to help animal preservation efforts in the world of warming – which is 12 percent of Norway types It is classified as threatened. Highlighting the weaknesses in its cold types can also help inform new ways to support their elasticity, and better understand the risk of extinction.
