Hypothesis

What selective forces favour natural chimerism in coral kin settlements?

Conclusion

The study suggests that gregarious kin settlements in corals provide benefits in terms of increased size of the multi-partner entities, despite varying survivorship rates.

Supporting Evidence

  • Multi-partner entities exhibited the highest growth rates in the first two months.
  • Single genotype entities had the lowest survivorship rate at 54%.
  • Mixed allogeneic responses were observed, including tissue fusion and rejection.

Takeaway

Coral babies that settle together can either stick together or push each other away, and those that stick together can grow bigger and survive better.

Methodology

The study involved monitoring the growth and survival of 544 coral larvae in controlled laboratory settings over one year.

Limitations

The study was conducted in a laboratory setting, which may not fully replicate natural conditions.

Participant Demographics

Coral larvae from 10 different maternal colonies were used.
