Quaternary Plant Ecology Lab 
Stephen T. Jackson, University of Arizona

The Quaternary Plant Ecology Laboratory (QPEL) focuses on understanding ecological responses to environmental changes of the past, present, and future. In most of our work, we use archives of past ecological and environmental changes to inform knowledge of present and future ecosystems. We use a variety of paleo-archives, particularly tree-rings, woodrat middens, and sediments of lakes and peatlands. We are also concerned with improving understanding of how these paleo-archives record information on past ecosystems and environments.
