The main objectives of the project were: - the drawing up of the inventory of marmots in the different countries; - analyzing the dynamics of the resource from field stations; - preserving the genetic diversity of Eurasian marmots in situ and ex situ. Six species of marmots were studied (Marmota bobac, M. baibacina, M. camtschatica, M. caudata, M. marmota, and M. menzbieri,). Two of them are considered as locally endangered (M. camtschatica, Red Book of Yakutia; M. menzbieri, Red Book of Kazakhstan). To set long term monitoring, 11 field stations were created, two in forest-steppe zone (M. Baibacina); five in steppe zone (M. Bobac); one in tundra (M. Camtschatica) and three in the Alps (M. Marmota). Capture-Marking-Recapture programmes were initiated. Six expeditions were carried out for collecting marmot tissue and ecological, behavioural and abundance data, three in bobac range (Orenburg region and Barkortosan republic), one in Kazakhstan (M. Baibacina), and one in Yakutia (Ust-lenky reserve). Distribution maps were actualized in Kazakhstan and in Russia. M. Bobac population increased when M. Camtschatica and M. Menzbieri decreased steeply. M. Caudata needed protection. Data bases were developed. The results obtained in two industrial husbandry (Moscow and Leningrad regions) were analyzed. Three experimental farm were maintained (Kamchatka, Yakutia, Ukraine) and a new one is in development in the Moscow region. Re-introductions were realized in Russia (M. Bobac, Volga region; M. Camtschatica, Kamchatka), in Ukraine (M. Bobac), in Kazakhstan (M. Baibacina). The colonization process of M. Marmota was monitored in three late re-introductions (Apennines, Italy; Spanish and French Pyrenees) and in a recent one (Drôme, France). Behavioural ecology data were collected on spatial and social organization. Ecophysiologic and flea data were analyzed in the maintenance of plague foci. Species and geographical variability in marmots were studied through morphometric, caryotypic, DNA and electro-acoustical analysis of alarm call. The existence of two sub-species of M. Bobac and three sub-species of M. Camtschatica was confirmed. The research has produced, between 1994 and 1996, 174 scientific and technical publications. Results were exposed in two International conferences on marmots and three national seminars.
