Article Description

On Ile de la Possession, as on all the subantarctic islands, major compounds of organic nutrients are provided by avifauna. The presence of Wandering Albatrosses (Diomedea exulans) induces great perturbations in the environment at the site of their nest building activities: physical and chemical modifications of the soil (by removal of litter material for nest building, trampling and accumulated organic deposits) as well as microbiological, botanical and faunal changes. These perturbations are very localized in extent. The pedological changes have been described in terms of morphological modifications. The influence of Wandering Albatrosses on the vegetation and the invertebrate fauna has been assessed and shows a decrease in the number of plant species and an increase in the number of invertebrate species. The role of some of these as indicator species is discussed. © 1987 Springer-Verlag.
