Pfister Lab

Welcome to Cathy Pfister’s website

I am a Professor in the Department of Ecology and Evolution, The Committee of Evolutionary Biology, and the co-Director of The Microbiome Center at the University of Chicago

New Publications in the lab

Weigel & Pfister. The dynamics and stoichiometry of dissolved organic carbon release by kelp, Ecology

Brooke leads an experimental study, using stable isotope analyses, that shows that the bull kelp Nereocystis releases 16% of recently fixed carbon as dissolved organic carbon. Link

Bitter, Kapsenberg, Silliman, Gattuso, Pfister. Magnitude and predictability of pH fluctuations shape plastic responses to ocean acidification. The American Naturalist

Mark Bitter leads an experimental study that shows that populations differ in gene expression plasticity in response to fluctuating pH. Mussels from habitats with large pH fluctuations and low predictability display reduced phenotypic plasticity.

Weigel & Pfister. Oxygen metabolism shapes microbial settlement on photosynthetic kelp blades compared to artificial kelp substrates. Environmental Microbiology Reports

Brooke Weigel leads an in situ experimental study showing how the bull kelp surface entrains a unique microbial community. Link

Mark Bitter earns his PhD!

Brooke Weigel named Harper Fellow, 2020-2021

Brooke received the prestigious University of Chicago’s William R Harper award to recognize her dissertation.

Another publication from Mark Bitter's thesis:

Mark Bitter’s publication on mussel response to ocean acidification is published:

Bitter, M.C., Kapsenberg, L., Gattuso, J.-P., Pfister, C.A., 2019. Standing genetic variation fuels rapid adaptation to ocean acidification. Nature Communications 10, 5821.

Kudos to our Ecology class for safe and fun outdoor labs in Fall 2020. Read the UChicago story here
