Dr. Theodose joined the Biology Department at USM in 1995. She is a plant ecologist with expertise in salt marsh communities.

Dr. Theodose regularly teaches courses in general ecology (BIO 203), plant ecology (BIO 383), and botany (BIO 231). She also teaches the second semester course, which focuses on organismal biology (BIO 107), in the introductory biology sequence, as well as the biology lab course for nonmajors (BIO 102).

Research Interests

I am interested in how nutrient levels influence plant community dynamics within ecosystems.  I have a special interest in ecosystems that are stressful to plant growth, such as alpine areas, peatlands, and salt marshes.  Current work in my lab is focused on invasive species and how anthropogenic eutrophication influences their abundance at the expense of that of native species.
