Abstract

fetched live from OpenAlex

This work aims at describing benthic bacterial, archaeal, and metazoan communities along a geographical gradient to assess the effects of a shrimp farm (releasing organic matter such as uneaten feed and faecal pellets) on these communities. The samples were collected in several benthic stations from 0 m to 200 m from the farm cages, as well as in another station located several kilometers from the study area. This study includes two datasets: one based on 16S rRNA gene sequencing, which characterizes the bacterial and archaeal communities, and the other based on 18S rRNA gene sequencing, which describes the metazoan communities.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
