7,363 sites: river distance is the dominant occupation predictor
- what the source states
- "We updated previously published models of the likely distributions of pre-Columbian people using 7,363 locations within Amazonia sensu stricto from the AmazonArch database." "Distance from river… was the most important predictor variable and accounted for 21.5% of the permutation importance in the pre-Columbian model." The updated models "differentiate probabilities of occupation in interfluvial areas that were more sparsely populated than those close to rivers."
- limitations
- Site databases inherit survey-effort bias toward accessible riverine areas.
