This study take into account a small number of social groups of marmots in a moderately high mountain (2300 m high) in the northern part of the village of Aussois (Savoie, Haute Maurienne). In this area the ecological conditions are diverse (slopes, exposure, vegetal cover, rocks). It is also diverse for the pressure exerted on marmots by visitors. We compared the different space occupations by marmots in relation with the fact that their home-range is close to a footpath or is free of human frequentation. A study using 30m quadrates, processed with the statistical programme ADE, showed that marmots adapted their behaviour to human pressure : the more disturbed marmots stayed closer to their burrow than less disturbed marmots.Compensation in feeding is obtained by a shift in the daily distribution of survival activities, particularly feeding.
