Abstract

fetched live from OpenAlex

Although hydrostatic pressure is one of the most prominent abiotic drivers of faunal \nbathymetric ranges, it is one of the least understood. As climate change drives warmer \ntemperatures, it is hypothesized that benthic communities may undergo vertical shifts \nfrom shallow to deeper depths. Expanding our understanding of the impact of pressure on \nmarine organisms is therefore important. Here, I first synthesized and analyzed >130 \nstudies reporting survival of >260 shallow and deep-sea taxa after exposure to non-native \npressure. Many deep-sea species survived and bred under low or atmospheric pressure \n(slightly below sea surface depth), especially those from higher latitudes, and tolerance in \nadults was influenced by phylum. Next, I used high-pressure chambers to test the \nresponse of several subtidal echinoderms to various pressure levels, durations and pH \nconditions. Responses to acute pressure shifts suggest that deep-sea species are relatively \ntolerant to depressurization, but shallow-water species are less likely to maintain critical \nbehaviours if moved to pressures beyond their current bathymetric ranges.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
