- LiDAR surveys over 4,430 km of flight in southwestern Amazonia revealed five times more earthworks than previously detected by satellite imagery, with 432 earthworks documented, of which only 36 were known before.
- The Aquiry civilization's geographical extent is now estimated at about 183,000 km², tripling earlier estimates, and the total number of earthworks in the region is projected to be 24,000–30,000.
- The population of the Aquiry civilization around 100–300 AD is estimated at 1.25–3 million people, based on earthwork counts, labor requirements, and comparisons with later mound villages.
- The study challenges previous assumptions about Amazonian population density, suggesting that the southern rim alone may have held up to 6 million people, requiring re-evaluation of precolonial demographics and environmental impacts.
