The efficacy of such mutualisms can be crucial to the population dynamics of one or both partners, particularly where survival bottlenecks occur at early life stages. In laboratory and field outplant experiments, we explored determinants of the onset of mutualistic interactions between early stages of branching corals and their trapeziid crab partners. We confirmed that recently settled crabs are capable of providing housekeeping services to their young coral partners (as has been reported for older crabs and corals), and the presence of a crab in areas of high sedimentation conferred growth benefits ~3 times as strong compared with low sediment conditions. We also showed that recruitment of post-larval crabs to very young corals increases with morphological complexity of the coral, which relates to the ability of the host to provide micro-refugia for its crab symbiont, and indicates the potential for selective pressure for traits that attract and retain crabs during this high-mortality bottleneck life stage. These findings provide insight into the recruitment process and ontogenetic constraints that influence the onset of mutualistic interactions between corals and their associated symbionts.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
