In the Ecuadorian River Valley, the “lost city of Amazon” added corn and planted the Elder trees for more than 1,200 years, but later a profession that lasted only 300 years was that changed the jungle environment.
A new research led by Professor Mark Bush at the Florida Institute of Technology and Professor Crystal McMyl at Amsterdam University was used by the Microphoselus from the lake of Lake Corner to provide the first detailed view of 2,700 years in the Valley of the Valley in the Valley.
“Amazon’s Lost City Environmental Ligas and Recent Maps” published today Nature communications.
His work is based on the current archaeological study, in which more than 7,000 structures hidden by the forests of the Valley are documents, which some researchers have described as the lost city of Amazon.
“Our study provides a better human activity timeline in the Valley,” said Bush, who led the World Environment Institute in Florida Tech, because we see that people go into and out of different styles of land and go out.
In about 750 BC, the Apunan civilization began their occupation of the valley. About AD 250, their influence on this area began to weaken about 550 before disappearing. The authors have denied a current idea that a major ashfall from the Singh volcano caused the abandonment, rather than that it was gradually decreased in several hundred years.

After abandoning, the forest closed on the signs of human presence until a new wave of occupants reached around 1500. They cultivated maize until they abandoned the land around 1800. The length of this jungle is rich in palms, which created a type of jungle that was not seen in Hazaria earlier.
The authors have concluded that the combination of climate change and human influence has created modern forests in the river Valley and although these forests look natural, they have been in their modern form for only 200 years.
“This task highlights the importance of seeing the past to understand the current,” said co -author McMyl.
The modern forests around Lake Carmourne are protected by Singh National Park.
