Description :
The consumption of Mountainepine seeds by small vertebrates before their dispersal was studied in a forest of the Eastern Pyrénées (Osseja, 42o 23' N, 2o E). Seed production was estimated and predation signs (exploited cones, seed wings) convertible into numbers of seeds eaten by each identified consumer, were counted. The total rate of predation on the 1981 production ranged from 20 % in the densest areas to 32 % in the clearings.
