New Publications and Events in the Lab
New paper with Jessica Mark Welch’s group on visualizing the kelp microbiome. See microbial diversity on the bull kelp.

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
Kelp studies and restoration featured in a Seattle Times article
Bitter, Kapsenberg, Silliman, Gattuso, Pfister. Magnitude and predictability of pH fluctuations shape plastic responses to ocean acidification. 2021. The American Naturalist 186:582–593.
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.
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.
