WEATHER
CONDITIONS

|
|
|
Weather conditions: |
| Huge snowbanks under coastal scurs melted completely only in August, which is indicative of higher snow accumulation during winter compared with the previous year. The period from 25 June to 15 July was colder and more rainy than in 2000, while period from 15 July to 2 September was, probably, slightly warmer than in the previous year. Emergence of mosquitos occurred in the middle of July which is a week later than in 2000.

Breeding conditions:

As in previous year Snowy Owls and Rough-legged Buzzards were never seen in the period of studies. Long-tailed Skuas were notably less abundant than in 2000, but wandering Arctic and Pomarine skuas were common in June-July, while in 2000 two latter species were not recorded. Arctic Foxes, Ravens, Glaucous and Herring gulls were common predators in the sea-side area (coast, stony talus and sea-side tundra).
First chicks in Thick-billed and Common murres appeared on 25 and 29 July, respectively, which did not actually differ from 2000 dates. Hatching in Crested and Least auklets was recorded on 28 and 26 July, which was 2 and 4 days earlier than in 2000. Reproduction in Thick-billed and Common murres and in Crested and Least auklets was successful. In contrast, breeding conditions were extremaly unfavourable for Kittiwakes, which nested in very low numbers, and hatching was recorded in a single nest on 14 August only.

Rodent dynamics:
|
| Voles were generally less abundant in tundra than in 2000, but they were still common, in particular Cletrionomys sp. in coastal stony talus and on the shore.
