About Me

Amy Zyck

I am a recent Ph.D. graduate and a current postdoctoral researcher in the Puritz Lab of Marine Evolutionary Ecology at the University of Rhode Island. My research focuses on how benthic marine organisms adapt to multiple human-driven environmental stressors. During my doctoral studies, I combined seascape genomics with laboratory seawater manipulation experiments to understand how stressors, like coastal acidification and hypoxia, can impact the early life-stages of oysters and, in turn, shape the connectivity of oyster populations. I utilized Expressed Exome Capture Sequencing (EecSeq) to identify and analyze putatively adaptive regions of the eastern oyster genome under exposure to multiple coastal stressors. By comparing adaptive responses across larval, juvenile, and adult oyster stages, I assessed the adaptive potential of oyster populations in the face of ongoing climate change. Committed to scientific rigor and transparency, I ensure all protocols and code from my current and future projects are openly available via this website and my GitHub account.

My Projects

Investigating how larval response to multiple coastal stressors shapes the distribution of genomic variation of adult oysters

A project using a seascape genomics approach to link larval oyster responses to multiple coastal stressors, adult oyster population genomics, and environmental data to determine how environmental stressors shape the adaptive divergence of wild oyster populations in Narragansett Bay, RI through selective pressures imposed on the larval stage.

Evolutionary responses of oyster larvae to prominent coastal stressors

A project using single-generation seawater manipulation experiments to investigate genomic and phenotypic responses of larval oysters to high-intensity, diel-cycling pH and dissolved oxygen exposures.

...   ...

Ecological and evolutionary implications of coastal stressor effects on interconnected life stages in the eastern oyster

A project using a single-generation, mutli-life stage seawater manipulation experiment to investigate how larval oyster exposure to high-intensity, diel-cycling pH and dissolved oxygen conditions impact the genomic and physiological responses of juvenile oysters under continued exposure.
