Recent data show a historical and dramatic decline in the Arctic summer sea ice extent. This is believed to be bad news for marine organisms living under the ice. But new research show that perhaps some of the species actually have adapted to minimal ice cover in summer… Recent studies predict that the Arctic Ocean will have ice-free summers within the next 30 years which presents some unprecedented challenges for the ecosystems in the high north. Not least the ice-associated crustaceans generally considered to spend their entire life on the underside of the Arctic sea ice. However, at least for some of the keystone ice associated organisms, the implications may not be as obvious and detrimental as assumed until now, according to a new article published in Biology Letters.
