Maynard Schaus received his B.S. in Biology from California Lutheran University and his Ph.D. in Zoology from Miami University (Ohio). Dr. Schaus's research on the role of fish in lake nutrient cycles has been published in several peer reviewed journals. He has conducted research in Florida on the effects of a large scale fish removal on the nutrient cycles of Lake Apopka. He has been involved with the campus green roof project, to examine the effects of green roofs on the nutrient content of runoff water. He has also worked with students on a variety of basic and applied ecology projects, including work on salt marsh bird community composition, nutrient uptake by stormwater management ponds, and the ecology of neotropical harvestmen. He has received funding from the St. Johns River Water Management District, and in collaboration with other Virginia Wesleyan faculty members has received funding from EPA and NSF.
