African Botany and Ecology Studies

The Birds and the Seeds When species are lost from ecosystems through local extinction, the pattern of ecological interactions changes. Galetti et al. (p. 1086 ) show how the loss of large fruit-eating birds from tropical forest fragments in Brazil affects the reduction of seed size in a palm species. A data set was compiled that consisted of >9000 seeds measured in 22 populations over a large area of Atlantic rainforest, including seven areas where large-seed dispersers (toucans, cracids, and large cotingas) were extinct and 15 areas where they are still common.
