Description

Shellfish are an important component of our ecosystems. As sessile filter feeders, shellfish offer a valuable resource for revealing how the nearshore can be negatively influenced by anthropogenic activity and natural processes. Research in our lab focuses on using transcriptomic approaches to interrogate physiological responses, which in turn provides important insight into environmental conditions. Several projects will be presented including lab-based trials as well as efforts to characterize natural oyster populations in Puget Sound. More recently we have developed global epigenetic and proteomic approaches that could provide new insight into contaminant exposure and physiological impact. The potential for epigenetic approaches to reveal xenobiotic exposure will be discussed in a broader taxonomic framework as we are just beginning to understand the landscape and function of epigenetic mechanisms such as DNA methylation in shellfish. New approaches and application of shotgun proteomics will also be discussed. Currently these approaches are not realistic solutions for routine monitoring of nearshore water quality, but do offer an un-biased means to develop stressor specific, simple assays for general use.
