Karen S. Oberhauser, Ph. D. University of Minnesota, Department of Ecology, Evolution and Behavior, Associate Professor, Department of Fisheries, Wildlife and Conservation Biology

The work of Karen S. Oberhauser is concentrated in invertebrate conservation and ecology. She has developed a decades long interest in the biology and the migration of monarch butterflies. She is known for encouraging the involvement of laypeople and students as "citizen scientists" who provide her and her researchers with data related to and ecological monitoring of the Monarch butterfly. This has resulted in the creation of a large number of participants with she considers a high degree of scientific and environmental literacy. She organizes and conducts many teacher training sessions.

Research

[edit]

The research of Karen Oberhauser focuses on several facets of monarch butterfly biology and (Danaus plexippus) ecology. Her work has been to develop theories of monarch reproductive ecology, fitness and mating patterns in both sexes, the prevalence and effects of a neogregarine protozoan parasite of monarchs, the distribution and abundance of immature monarch stages, and risks posed by global climate change.

Fostering environmental awareness

[edit]

she has developed programs to engage K-12 students and teachers in the study of science. Her program called Monarchs in the Classroom, conducts courses and workshops for teachers. She established nationwide Citizen Science project called the Monarch Larva Monitoring Project and distributes monarch eggs and larva at the classroom teachers.

She has been honored at the White House for her work with monarch butterflies. http://www.whitehouse.gov/champions/citizen-scientists/karen-oberhauser and http://discover.umn.edu/news/campus-community/white-house-honor-professor-karen-oberhauser-champion-change-citizen-science
