Researchers predict that future climatic change is likely to cause declines in reindeer abundances and their distribution at rates rarely seen over the last 21,000 years.

Reindeer, also known as caribou in North America, are an Ice Age species that have survived many episodes of Arctic warming. They are uniquely adapted to Arctic environments, where they regulate ecosystems and sustain the livelihoods of many Indigenous Peoples.

Being common is rather unusual. It’s far more common for a species to be rare, spending its existence in small densities throughout its range. How such rare species persist, particularly in an environment undergoing rapid climate change, inspired a 15-year study in arctic Greenland from the ɫ��ɫ.

Melting Sea Ice May Be Speeding Nature’s Clock in the Arctic

Spring is coming sooner to some plant species in the low Arctic of Greenland, while other species are delaying their emergence amid warming winters. The changes are associated with diminishing sea ice cover, according to a study published in the journal Biology Letters and led by the ɫ��ɫ.
