Pattern found in world’s rainforests where 2% of species make up 50% of trees

From the Amazon to Africa and south-east Asia, diversity among rainforest species follows the same rule, study shows

Just 2% of rainforest tree species account for 50% of the trees found in tropical forests across Africa, the Amazon and south-east Asia, a new study has found.

Mirroring patterns found elsewhere in the natural world, researchers have discovered that a few tree species dominate the world's major rainforests, with thousands of rare species making up the rest.
