Overview

Examines thermal tolerance modulation in black-lip pearl oyster, suggesting implications for ecological conservation.

Key Points

  • The research aims to understand how early thermal environments affect later-life thermal tolerance in black-lip pearl oysters.
  • Two bi-parental progenies of Pinctada margaritifera were examined.
  • Embryos were incubated at control (28°C) or warm (32°C) temperatures before hatching.
  • Spat were raised for four months in common conditions at 28°C.
  • Thermal tolerance was assessed at a sublethal temperature of 34°C.
  • Family-specific effects were observed, enhancing thermal tolerance in one lineage and reducing it in another.
  • Main molecular pathways for heat stress response were conserved across families.
  • Network analysis revealed subtle environmental 'memory' through gene regulatory pathways.
