COVER A leafless tree (Ceiba trischistandra) in Machalilla National Park, Ecuador. This species is a characteristic element of Ecuadorean and northern Peruvian tropical dry forest, particularly during the dry season. The large differences in tree species composition found in dry forests across the American tropics indicate that many conservation areas will be required to protect the biodiversity of these threatened formations. See page 1383.
