Résumé

Since 1989 a coordinated programme of research is performed on Alpine Marmot populations in order to define scientific basis for their management. 1. Sociospatial behaviour = living in family groups. We have shawn that marmots were ensocial animals - groups are composed of one male and only one reproductive female - the youngs of two or three former litter live together with the parents - reproduction seems to occur every two years - home range slightly overlap (10-15%) and range from 2 to 5 ha. Behaviour distribution show change according to time and space. 2. Settlment site selection. Main burrow systems are not dug at random - prefered ecological factors are medium slope, mixed vegetation and rock areas, southern exposure and a low anthropogenic pressure. A generalized linear model was defined for settelment. 3. Scent marking. Scent marking allow marmots to distinguish self-marked object from allo-marked object-frequency of scent marking is much higher near main burrow system than at the border of the home range - scent marking frequency decreases during sumner season - adults marked more than youngs. 4. Monitoring reintroduction. Marmot is the most often (re) introduced manmal in France - an assessment of reintroductions is in progress. Two (re) introductions sites are studied : one reintroduced last year, the other since 40s years. A new section of this programme is beginning including physiological, neurosensory, endocrinological, parasitological, socioeconomical and ethnobiological aspects - ten laboratories are working under my coordination with the support of the CNRS (equivalent in France of Academy of Sciences in Russia).
