Description

The goal of this project is to experimentally explore two mitigation approaches that may allow the shellfish industry to adapt in the face of worsening ocean acidification conditions. The first mitigation approach would be the expansion of the portfolio of cultured species to include those inherently resilient to OA. The second mitigation strategy would be to use husbandry practices that promote acclimation or adaptation of larvae via environmental priming of the parental generation. Parental priming, or parental carryover effects, occur when environmental stressors experienced by the parental generation have phenotypic effects on their offspring. 

The objectives of this project are: (1) Assess OA sensitivity of the native littleneck clam versus the non-native Manila clam in adult and larval stages under laboratory conditions and (2) Identify molecular mechanisms underlying parental carryover effects by comparing the transcriptional profile of gametes from clams conditioned in high pCO2 versus control conditions.

Biologists with bivalve husbandry experience, strong writing and communication skills, and experience analyzing transcriptome data are preferred.
