Abstract

fetched live from OpenAlex

A quarter century ago, the question was posed of whether a general hypothesis could explain population cycles of forest Lepidoptera. Since then, considerable progress has been made in elucidating mechanisms associated with cyclic dynamics of forest Lepidoptera. Delayed density-related parasitism and reduced fecundity during population peaks are common influences on population dynamics, although why fecundity declines is not understood. The hypothesis that sunspots explain cycles is rejected. The influences of delayed-induced plant defenses on populations are inconsistent, but interactions between plant chemistry, pathogens, and immunity remain rich areas for future study. Population dynamics of forest Lepidoptera can be synchronous over large geographic scales, and repeatable waves of spread of outbreaks occur for some species. Climate warming could modify species distributions and population cycles, but mechanisms have not been elucidated and changes in cyclic dynamics are not generally apparent. Integration of top-down and bottom-up influences on cyclic dynamics and quantification of dispersal are necessary for progress in understanding patterns of insect outbreaks.

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.
