Welcome to the Dept. of Plant Biology, Ecology, and Evolution!

We are a dynamic department devoted to understanding plant biology, from molecules to ecosystems. Our faculty have comprehensive research programs in Ecology & Evolutionary Biology and in Cell & Molecular Biology.   We regularly publish in top tier journals and are committed to excellence in teaching.  We provide opportunities for research experiences for our undergraduates through our B.S. Botany and B.S. Biological Science programs. Our Graduate Program offers an M.S. in Plant Biology and a Ph.D. in Plant Sciences. 

The Department of Plant Biology, Ecology, and Evolution Office is located in 301 Physical Sciences. Faculty have offices and labs in Physical Sciences, Life Science East basement, or the Henry Bellmon Research Center (Faculty Directory). The OSU Herbarium is in the LSE basement.

Regents Professor Dr. Michael Palmer recently completed a four-year term as a Vice President of the International Association for Vegetation Science (http://iavs.org/Home.aspx). This organization has European roots, but has expanded to represent the discipline from all continents (including a few scientists studying Antarctic plants!)  A benefit of the association is the annual symposium, which has recently been held in Estonia, Korea, Australia, Czechia, Mexico, and France. The symposium features not only formal talks, but excursions to visit natural vegetation and cultural landscapes.  The US has more IAVS members than any other county – and one of Mike’s largest challenges is to encourage these members to be more active in the affairs of the society. In particular, relatively few American students take advantage of the generous travel support offered by IAVS. Another challenge is to expand membership in underrepresented regions such as Asia and sub-Saharan Africa. Mike initiated the IAVS FaceBook Group (https://www.facebook.com/groups/iavs.org/), which has become an active site for sharing job announcements, events, and photographs of vegetation from around the world. Mike continues as editor of the Forum section of the two journals published by IAVS:The Journal of Vegetation Science and Applied Vegetation Science. Forum papers are meant to be an outlet for creative ideas that could be controversial or speculative, but which are also likely to spur future discussion and research. Mike engages the Young Vegetation Scientist section of IAVS in reviewing manuscript submissions to IAVS journals. This June he will lead a workshop in Brazil on how to write an effective manuscript review in Vegetation Science.
