Résumé

The annual life cycle of marmots one may imagine consist of subordinate ecological cycles – monocyclic reproduction, seasonal cycles in consumption of definite forage plants, fat reserves expenditure and deposition. The important should be the terms of synchronization of cycle and involved trigger mechanism. The general synchronization of annual cycle in marmots performed by hibernation. At the same time may exist system of the triggers of more subordinate level responsible for the synchronization of the cycles including with those originated from external sources, for instance, the relation of cycles in marmots and their forage plants. The seasonal cycle in movement of reserve compounds (the pool) in plants most probably catch by marmots. The geophytes, plants with resting bud located under earth surface, are characteristic by the reserve organs as bulbs, rhizomes and tubers. The visible marmot consumption of geophytes in vernal and autumn time seems as one of examples of the synchronization of cycles in marmots and their forage plants.
