Abstract

fetched live from OpenAlex

A simple, yet highly promising method of quantifying temporal diversity dynamics is to use the ratio of mean species richness, S, to potential species richness, P (cumulative S at a locality). In a rock pool meta-community of aquatic micro-invertebrates, this ratio, which we call the dynamics index (I), proved reliable as a predictor of assemblage type. We calculated within-habitat diversity dynamics for each of 49 pools that differed in environmental variability. The resulting dynamics indices provide an easily quantified measure of the diversity dynamics at various scales and, specifically, provide a measure of within-habitat temporal turnover in habitats where P can be reliably evaluated.

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.

Teacher imitation

Not 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.
