Short summary

We studied the responses of larvae of Macoma balthica to a range of future CO₂ scenarios using large mesocosms encompassing the entire pelagic community. We focused on the growth and settlement process of M. balthica when exposed to future CO₂ levels, and found the size and time to settlement to increase along the CO₂ gradient, suggesting a developmental delay. The strong impact of increasing CO₂ on early-stage bivalves is alarming as these stages are crucial for sustaining viable populations.
