Abstract

The effect of the Antarctic tourism, as anthropogenic factor, on a total abundance and breeding success of the gentoo penguin, Pygoscelis papua, in the region of the station Academic Vernadsky (Archipelago the Argentina islands) was researched. The total abundance of these penguins for the last decade has increased almost twice on a background of triple increase of a number of tourist visitations of this locale. We mark a stable high breeding success of this species, which does not depend on a level of recreational usage of region. The augmentation of elimination of brooding by predators (skuas) in colonies, which are visited by the tourists, is absent. The obtained results do not give the basis to consider tourism (in its existing forms) as the factor, which essentially influences abundance of gentoo penguins.
