Birth of wild tapir offers hope for Brazil's endangered ecosystem

Researchers believe the calf was born in January and a second may be on its way

Hopes for a recovery of Brazil's most endangered ecosystem have been given a boost by the first birth of a wild tapir in Rio de Janeiro's Atlantic Forest for more than a century.

Scientists said video clips of the baby tapir proved the initial success of a re-introduction strategy for the threatened mammal, which is often described as "a forest gardener" because it plays a vital role in the dispersal of seeds.
