Intracellular acid-base regulation mediates a trade-off between shell and somatic growth in a clam under ocean acidification

Year: 2026

Type: article

Abstract: -ATPase (NKA) was synergistically upregulated, suggesting an evolved adaptive pathway. Dynamic energy budget (DEB) modeling, calibrated with experimental data, revealed that this cellular compensation carries a high energetic cost, leading to a significant reallocation of resources: Shell growth was maintained, but somatic growth was severely suppressed. These results elucidate a conserved cytoprotective mechanism that enables short-term tolerance of OA at a substantial somatic cost, redefining resilience to include energetic trade-offs.
