About the Cover


(Top) White-tailed tropic bird, Phaethon lepturus lepturus; (lower left)adult scared ibis, Threskiornis aethiopica abbotti; and (lower right ) juvenile red-footed boobly, Sula sula rubripes. These birds are among the hundreds of species of animals and plants whose habitate may be destroyed if plans proceed for establishing a communications center on the island of Aldabra, northwest of Madagascar. Among the animals affected would be the almost extinct giant land tortoise.See page 8.[Roger Garmer, University of Bristol, England]
