Hypothesis
The evolutionary response of larval development rates in coastal invertebrates to ocean acidification can be quantified.
Conclusion
The sea urchin Strongylocentrotus franciscanus may evolve faster than the mussel Mytilus trossulus in response to future ocean acidification conditions.
Supporting Evidence
- The study found that S. franciscanus has greater genetic variation for larval size under future CO2 conditions.
- Simulations indicated that S. franciscanus could reach low CO2 phenotype within 50 years of selection.
- Maternal effects were significant in both species, influencing larval size regardless of CO2 conditions.
Takeaway
This study looks at how two sea creatures, a sea urchin and a mussel, might change over time as the ocean gets more acidic. The sea urchin can adapt faster than the mussel.
Methodology
A full-factorial breeding design was used to measure larval development rates under different CO2 conditions.
Potential Biases
Potential biases may arise from the specific environmental conditions and limited geographic sampling.
Limitations
The study primarily focuses on two species and may not represent all marine invertebrates.
Participant Demographics
The study involved larval development of two species: Strongylocentrotus franciscanus and Mytilus trossulus.
