Selezione dell'habitat da parte di Marmota marmota nelle alpi orientali della Svizzera. Habitat selection of Marmota marmota in the eastern Alps of Switzerland [Sélection de l'habitat de M. marmota dans les alpes orientales de Suisse].

Résumé

Marmota marmota is widely distributed in the study area. It is only lacking where human settlements are found, in the fertilized meadows lower down and in the forest. The serpentin arrea on the Totalp is very sparsly inhabited. The marmot can be found at heights between 1800 and 2900 metres above sea level, most of them being found between 2100 and 2600.Southerly slopes are generally not preferred. The marmot may be found in nearly all types of vegetation above timber line. The complexity of the vegetation is very important for the occurence of the marmot. In the study area the marmot has only been marginally influenced by tourism.
