Life histories and niche dynamics in late Quaternary proboscideans from Midwestern North America: evidence from stable isotope analyses

This study uses stable isotope analysis of mammoth and mastodon remains to examine ecological and behavioral changes during the late Quaternary, revealing increasing niche overlap and seasonality as these species approached extinction.
