WEATHER CONDITIONS

Season phenology: early

Weather conditions:

Within southern and typical tundras, spring was exceptionally hot and quick: on 23 May air temperature exceeded +20øC and it was the same up to the end of June. The ice on rivers broke-up on 26-31 May, all seasonal phenology took place about one month earlier (!) than usual. Summer was cool and wet with summer-floods, especially intensive in mid-July.

BIOTIC CONDITIONS

Rodents abundance evaluation:

high

Breeding conditions:

The density of Arctic Foxes was high in the northern part of the area and low in the south. Snowy Owl, Rough-legged Buzzard, Hen Harrier and skuas bred numerously and successfully.
 

Rodent dynamics:

Within typical tundras and in northern part of southern tundras the number of both lemming species (Siberian Lemming and Collared Lemming) and Narrow-skulled Vole was maximal. In the southern part of the southern tundras, the abundance of Siberian Lemmings was high, it was maximal for Narrow-skulled and Ruddy Voles, and it was also high for some other small mammals (Short-tailed Vole, Ground Vole and Arctic Shrew).
