Jon Doubek

Jonathan joined the Carey Lab in Fall 2013. His primary research focus is quantifying how multiple stressors (e.g. land use changes, climate change, invasive species and nutrient loading) affect lake planktonic communities, which have resulting consequences for lake water quality and human use. He combines field research, laboratory experiments, and ecosystem modeling to examine how each of these aspects individually influences lake food webs, but also how these different stressors can interact for combined effects.

Jon developed an early appreciation for freshwater science while growing up in the Upper Peninsula of Michigan. He earned his B.S. and M.S. from the University of Michigan -Ann Arbor in the fields of Ecology, Evolution and Conservation Biology. His M.S. thesis utilized isotope spectrometry in examining zooplankton food web relations in the Laurentian Great Lakes. In addition, he explored how land use changes and nutrient loading affect lake cyanobacterial dominance and how phytoplankton biovolume and composition can influence lakeside property values.

During his education at the University of Michigan, Jon worked with the City of Ann Arbor for a few summers. He collected and analyzed weekly water samples in the lab and provided the City with a final report to help inform management decisions. He aided the Huron River Watershed Council (HRWC) by directing and educating volunteers in water quality monitoring and environmental stewardship, and by providing feedback and updates to Michigan governmental agencies on the water quality status of the Huron River. Jon also collaborated with research scientists from the United States Geological Survey on historical zooplankton food webs in the Great Lakes region.
