| Outline of Final Research Achievements |
This study examined the effectiveness of seed dispersal by animals for the two species of large-seeded plants in a tropical dry forest in northwestern Madagascar. Both tree species depended only on a largest frugivore, the brown lemur, for seed dispersal. Brown lemurs removed 60-90% of produced seeds by mother trees of Astrotrichilia asterotricha (Meliaceae). The two tree species showed different survival rate and growth rate because of the specific fruiting periods, morphological traits of seeds, and germinating patterns. Therefore, significance of seed dispersal by the brown lemur diversified in the reproductive strategies of plants.
