Education and Career

She completed a bachelor of arts degree in biology at Harvard College, a bachelor of science degree in natural science education at the University of Wisconsin–Madison, and a PhD in ecology and behavioral biology at the University of Minnesota.^[2] Oberhauser is an adjunct professor in the Fisheries, Wildlife and Conservation Biology department and former director of the Monarch Lab at the University of Minnesota.^{[1] [3]} In October, 2017, she became the Director of the University of Wisconsin–Madison Arboretum, located in Madison, Wisconsin.

Research

A strong proponent of citizen science, as well as environmental and scientific literacy, Oberhauser has been studying monarch butterflies since 1984.^[4] Her research has addressed many aspects of monarch butterfly (Danaus plexippus) ecology, including reproduction, parasites, factors influencing immature monarch distribution and abundance, and impacts of insecticides, global climate change, and genetically-modified crops.^[5]

In addition to authoring many publications in scholarly journals, she was also co-editor for two books published by Cornell Press:

• The Monarch Butterfly: Biology and Conservation {{ISBN|978-0-8014-4188-2}}
• Monarchs in a Changing World: Biology and Conservation of an Iconic Butterfly {{ISBN|978-0-8014-5315-1}}^[6]

In 2013, she was named a Champion of Change for Citizen Science by the White House.^[7] "Professor Oberhauser represents the best and the brightest in our faculty here at the University of Minnesota. Her work with citizen scientists, teachers and elementary school students exemplifies the deep importance we place on public engagement, which is a core part of the University’s land grant mission," stated UMN President Eric Kaler in a UMN Press Release.^[8]

Oberhauser has been director for the Monarchs in the Classroom Program, president of the Monarch Butterfly Sanctuary Foundation^[9] and director of the Monarch Larva Monitoring Project.^[7]

In 2014, Oberhauser and a colleague published a scientific article examining how usage of Monsanto's Roundup herbicide on farmland in North America contributes to the decline of milkweeds, important food sources for the butterflies.^[10] They found that the size of populations of milkweed were smaller in areas of increased Roundup use, suggesting that the loss of this food source may contribute to the decline of monarchs. The milkweed limitation hypothesis as this has become known, has been tested by other groups of scientists finding conflicting results.^[11] Thus, the actual contribution of Roundup use and loss of populations of milkweed to the decline of monarch butterflies is still unclear.

Personal life

Oberhauser grew up in Wisconsin and married Don Alstad in 1985; the couple has two daughters. Don died in April 2014 at the age of 67.^[12]
