Genomic resource development for shellfish of conservation concern
We recently published the sequenced transcriptomes (suite of expressed genes) of pinto abalone and Olympia oyster in the journal Molecular Ecology Resources. The focus of this study was to identify genomic resources to aid conservation efforts for these two native shellfish species. Historic commercial exploitation has depleted native populations of pinto abalone and Olympia oyster along the west coast of the United States. Habitat degradation and climate change have contributed towards inhibited recovery of both species. A better understanding of the species’ transcriptomes and genomes...

If anyone is interested in what a tenure package looks like (I know I could have benefited from a few more examples) I am making mine available here. Below is one of the tables I included, an attempt to quantify online science...
Read MoreEnvironmental stress can influence Hsp70 expression in a discordant fashion
In this month’s issue of the Journal of Shellfish Research, results from a research project carried out in the lab section of FISH441: Integrative Environmental Physiology was published. David Metzger, a recent graduate from our lab, is the first author on the paper entitled: Characterizing the Effects of Heavy Metal and Vibrio Exposure on Hsp70 Expression in Crassostrea gigas Gill Tissue. Not only does this work demonstrate a role of HSPs in metal exposure, but nicely demonstrates that gene expression and protein expression can be inconsistent. An excerpt from the manuscript: This...
Read MoreCould lipid content in shellfish diet impact immune signaling?
Most people might only associate ceramide with a key ingredient in hand lotion, however Emma Timmins-Schiffman’s recent paper “Characterization of genes involved in ceramide metabolism in the Pacific oyster (Crassostrea gigas)” sheds light on a role for ceramide in responding to stress. Specifically, Emma examined the role of ceramide in adult oysters’ physiological response to being experimentally challenged with the pathogenic bacteria, Vibrio vulnificus. Two genes demonstrated increased expression during the bacterial challenge: a gene involved in hydrolytic...
Read MoreGenomic Resources for Pacific Herring
Our paper on gene discovery and SNP development in Pacific herring using 454 pyrosequencing just came out in PLoSone! Development of Genomic Resources for Pacific Herring through Targeted Transcriptome Pyrosequencing Summary: Pacific herring support commercially and culturally important fisheries but have experienced significant additional pressure from a variety of anthropogenic and environmental sources. In order to provide genomic resources to facilitate organismal and population level research, high-throughput pyrosequencing (Roche 454) was carried out on...
