Understanding the mechanisms by which individual organisms respond and populations adapt to global climate change is a critical challenge. The role of plasticity and acclimation, within and across generations, may be essential given the pace of change. We investigated plasticity across generations and life stages in response to ocean acidification (OA), which poses a growing threat to both wild populations and the sustainable aquaculture of shellfish. Most studies of OA on shellfish focus on acute effects, and less is known regarding the longer-term carryover effects that may manifest within or across generations. We assessed these longer-term effects in red abalone (Haliotis rufescens) using a multi-generational split-brood experiment. We spawned adults raised in ambient conditions to create offspring that we then exposed to high pCO2 (1,180 μatm; simulating OA) or low pCO2 (450 μatm; control or ambient conditions) during the first three months of life. We then allowed these animals to reach maturity in ... : Funding provided by: National Science FoundationCrossref Funder Registry ID: https://ror.org/021nxhr62Award Number: 1650042 Funding provided by: National Science FoundationCrossref Funder Registry ID: https://ror.org/021nxhr62Award Number: 1456724 Funding provided by: National Science FoundationCrossref Funder Registry ID: https://ror.org/021nxhr62Award Number: 1829976 Funding provided by: California Sea GrantCrossref Funder Registry ID: https://ror.org/02yn1nr06Award Number: NA18OAR4170073 Funding provided by: United States NavyCrossref Funder Registry ID: http://dx.doi.org/10.13039/100009896Award Number: N62473-2-0023 ...
