Brazil rainforest deforestation leads to seed shrinkage
By Rebecca Morelle
Science reporter, BBC World Service
The destruction of tropical rainforests is having an even greater impact on the environment than was previously thought, a study suggests.
Scientists have found that deforestation in Brazil is causing trees to produce smaller, weaker seeds that are less likely to regenerate.
They believe this has been triggered by the loss of large birds from the forests, which have beaks big enough to feed on and disperse the seeds.
The study is published in Science.
