Join Dr. James Lendemer on Feb. 3 2014 at 7 p.m. for an examination of how large-scale changes in the lichens of North America may be impacting large-scale forest health and the buffering capacity of ecosystems during periods of high environmental stress. It will highlight these issues and place them in the broader context of new assessments of lichen diversity in the United States. Monday, Feb. 3, 2014 - 7 p.m. at the University of Colorado Museum of Natural History Paleontology Hall
