Aerial photo of Dipteryx oleifera trees (IMAGE) University of Texas at Austin Caption The spatial distribution of purple-blooming Dipteryx oleifera trees on Barro Colorado Island, Panama. Our analysis reveals that for this species, the distance between an adult tree and its nearest neighbor is 5.5 times as far as expected based on where the seeds fall, and each tree has only 2% of the neighbors expected within 20 meters. The average distance to which seeds are dispersed is estimated to be 16.8 meters.
