For the better part of the last half-century, the Amazonian forests have been plagued by deforestation from human farming activities.

The city of Manila holds the human world record for the most densely populated space and now an international team of ecologists are seeking the natural equivalent, the most species rich area on earth.

Climate change, land use and other human-driven factors could pit savannas and forests against each other by altering the elements found by Princeton University researchers to stabilize the two.

Scientists report they have found that savannas prevailed most of East African sites where human ancestors and their ape relatives evolved for the past 6 million years.

Can a road-trip across eastern North America, ancient ice sheets, and DNA samples unlock the ancestral history of jack pine trees?
