Population ecology of geese in relation to natural and human predation pressure

Ziel



Three goose species, the dark-bellied brent goose, the red-breasted goose, and the lesser white-fronted goose nest almost exclusively on the Taymyr-peninsula in northern Siberia. All three species were endangered in the recent past, and only the population of the first one has recovered in numbers since the 1970s. This joint study is a follow-up of a study of the factors determining the breeding success of brent geese (condition of the birds built up on the wintering grounds, predation by arctic foxes and herring gulls mediated by three-year-cycles of lemmings) on the Taymyr-peninsula, extended to comparative research on the two other (still endangered) species.

All three goose species have in common that they are small, and thus vulnerable to predation by arctic foxes. This important arctic predator will therefore be studied in great detail. Fox movements will be studied by using modern satellite transmitters. In order to understand the predatory behaviour of arctic foxes, alternative prey, particularly two species of lemmings, will be studied as well.

The study will be conducted during the summer months on three different locations on the Taymyr Peninsula. The field work will be carried out in close co-operation with the administrations of the Great Arctic Reserve in Dudinka and of the Taymyr State Nature Reserve in Khatanga.
