Jaguars, tapirs, giant anteaters and spider monkeys have become "virtually extinct" in Brazil's Atlantic forest, while other species are being lost faster than previously believed due to the fragmentation and emptying of the once dense canopy by farmers and hunters, according to research published.
About 90% of the original Atlantic forest, which once covered an area of about 1.5m km sq (about six times the size of Britain) has been converted to agriculture by cattle ranchers, cocoa farms and rubber plantations.
