Never heard of glacier mice? Actually, they are small moss balls forming on glacier surfaces. New research by UNIS and Nottingham Trent University shows that there is “hopping” life in these fluffy balls. Invertebrates such as springtails and water bears literally thrive (and survive) in this ice-cold environment.

A new study based on a 30-year period show that the ocean floor communities of both Kongsfjorden and Smeerenburgfjorden have changed dramatically. Existing organisms are replaced by warmth- and light-loving species. – A biological tipping point, according to the authors.

Calanus glacialis (Arctic feed) is a copepod species considered to be a key element in the Arctic ecosystem. It contains up to 80 % fat, but that’s not why we compare it to the avocado. Both the copepod and the avocado might be regarded as biological anachronisms; adapted to an environment that no longer exists.

There are over 500 species of insect, mite and other creepy crawly recorded from Svalbard. They play a vital role in the ecosystem, and it is therefore important to understand the biodiversity present in Svalbard so as to better understand ecosystem function and provide a baseline for future environmental change studies.

UNIS researchers have recorded large amounts of Norwegian spring spawning herring in Adventfjorden and Isfjorden. This represents the northernmost mass-occurrence of herring, and a significant extension of its northern distribution limits.

A warmer ocean climate has resulted in Atlantic cod and haddock extending further into Arctic waters, presenting a potential threat to the native polar cod which is an important part of the high Arctic ecosystem. However, a new study by scientists in Svalbard and Tromsø reveals there is little competition for food between the invaders and the polar cod.
