Abstract

fetched live from OpenAlex

Life-history research, commonly treated as the study of age and stage-dependent vital rates, often invokes a role for habitat but seldom in the context of theories of density- and frequency-dependent habitat selection. Merging life-history research with habitat selection theory is crucial because habitat and habitat selection modify the partial interactive effects of genetics, traits, demography, and environment on adaptive evolution. The density and frequency dependence of habitat selection feeds back onto life histories whenever the relationship between fitness and density varies among habitats and individuals occupy the habitat yielding highest fitness. Comparisons of life history and habitat selection in rodents, fishes, and fisheries support the habitat-dependent perspective but also reveal manifold processes in need of further theoretical and empirical study.

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.
