Ecological legacies and recent footprints of the Amazon’s Lost City

Mark B. Bush, Rachel K. Sales, David Neill, Bryan G. Valencia et autres

Once considered pristine forests, the mid-elevational forests of the eastern Andean flank are now known to have long histories of human occupation. Past habitations, such as the ‘Lost City of the Amazon’ in the Upano Valley of eastern Ecuador, were societally and …

A palaeoecological perspective on the transformation of the tropical Andes by early human activity

Mark B. Bush, Angela Rozas-Dávila, Marco Felipe Raczka, Majoi N. Nascimento et autres

Palaeoecological records suggest that humans have been in the Andes since at least 14 000 years ago. Early human impacts on Andean ecosystems included an increase in fire activity and the extinction of the Pleistocene megafauna. These changes in Andean ecosystems coincided …

Potential distributions of pre-Columbian people in Tropical Andean landscapes

Rachel K. Sales, Crystal N. H. McMichael, Suzette G. A. Flantua, Kimberley Hagemans et autres

Much has yet to be learned of the spatial patterning of pre-Columbian people across the Tropical Andes. Using compiled archaeological data and a suite of environmental variables, we generate an ensemble species distribution model (SDM) that incorporates general additive models, random forest …

Chitinozoan Biodiversity in the Ordovician of Gondwana: An Interval-Free Approach Using the Quantitative Stratigraphic Correlation Program CONOP9

Rachel K. Sales

The purpose of this study is to examine the biodiversity patterns of a group of fossil organisms called chitinozoans. Chitinozoans are organic-walled, planktonic microfossils that first appear in the Early Ordovician Period (488 million years ago) and diversify rapidly through the Paleozoic …
