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:
A COVID-era outdoor and mobile field lab for studying kelp performance in Washington coastal waters. Fits in the back of a minivan.
