Live fast, die young strategy spawned Amazon tree boom

A "live fast, die young" life history strategy could have been a key factor behind today's high tree diversity in the Amazon, scientists have suggested.

 

The researchers hope the findings will shed light on why some groups of trees in the biodiversity hotspot contain hundreds of species.

 

An estimated 16,000 tree species - about 30% of the recorded total worldwide - are found in the Amazon.

The results have been published in the journal Ecology Letters.

 

 

"One of the big questions about understanding the biodiversity of the Amazon rainforest is why have we got a range of groups of trees that contain so many species," explained co-author Tim Baker from the University of Leeds.

 

"There are genera - or groups - that are very species rich; some of them have 100, 200 or 300 species in them but we have not had a good reason for why these species-rich genera exist."
