Abstract
This research investigated the life history and demographics of exploited, tropical seahorses. My thesis was designed to use the unusual morphology of seahorses (Hippocampus comes and H. spinosissimus in the central Philippines), to test the life history structure and strategies of tropical reef fishes. I then made direct use of ecological findings in order to evaluate risk associated with the capture of tropical seahorses for active and growing international markets. Hippocampus comes has a broadly bipartite life history comprising three biologically distinct phases; planktonic newborns, settled juveniles and adults. Most vital rates that govern the population turnover of H. comes confer low susceptibility to risk. Simultaneously, aspects of abundance (range and distribution), developed parental care, behaviour and susceptibility to fishing, increase the species' inherent vulnerability. Stage-structured matrix models examined the outcomes of temporal closures and size-based harvesting for managing artisanal seahorse fisheries. Simulations showed that when fishing occurred throughout the year at relevant intensities, slot sizes provided better protection for populations than minimum size limits, as well as greater cumulative catches over 10 year time horizons. The ontogenetic ecology of tropical seahorses is comparable to most warm-water reef fishes, sharing: 1) a broadly bipartite life history, 2) dispersal likely to confer demographic connectivity at the scale of 10s-100s of km, 3) young that advect passively early in the pelagic phase, and 4) ontogenetic habitat associations that segregate benthic individuals into multiple ecologically distinct stages. Unusually, seahorses have: 1) a pelagic phase inferred to last between 5-

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.
