BIOTIC
CONDITIONS
|
| Rodents abundance evaluation: |
low
|
|
|
Breeding conditions:
|
| The spring 1995 was phenologically average and waders started breeding in average for the area dates with high density. Predation by Arctic foxes was weak in the first half of incubation, but increased dramatically in the second resulting in a low overall nest success about 10%.
|
|
|
Rodent dynamics:
|
| Lemming numbers were low, animals being occasionally met in mid June, and then almost completely dissappearing in July.

Rodent species recorded:
|
| Latin | Abundance |
|---|
| Lemmus sibiricus | rare |

Summary
of fauna studies: |
| The studies carried out from 1994 to 1997 were focused on relating wader numbers and breeding success to environmental conditions. These studies have shown that abiotic conditions on a season's start had controlled to substantial extent the wader breeding numbers, in particular these of nomadic species. Nest success of all species was primarily determined by abundance of lemmings as alternative prey for mammalian predators, in agreement with prey-switching hypothesis.
