Replication requests

Does symbiont shuffling explain recovery after the 2024 heatwave?

The claim to test: colonies that shifted to clade D recovered 40% more marine cover within 12 months (the original authors, 2026). Any lab may register a plan; every attempt is recorded on the original paper.

The claim
Colonies that shifted to clade D symbionts recovered 40% more live marine cover within 12 months than colonies that did not.
