BIOTIC
CONDITIONS
|
| Rodents abundance evaluation: |
high
|
|
|
Breeding conditions:
|
| High lemming density was also illustrated by patterns displayed by predators, with records of fledged Snowy Owls and Long-tailed Skuas and also reproduction among Arctic Foxes. The non-occurrence of an outbreak on Traill Island and this particular and deviating situation recorded from Ymers Island raise many new questions about lemming cycles in North East Greenland.
|
|
|
Rodent dynamics:
|
| Based on direct observations of lemmings, records of active burrows and greater aggregations of winter nests, there was evidence that lemmings had experienced an outbreak.
