Abstract

fetched live from OpenAlex

Global climate change models predict an increase in the frequency and severity of extreme temperature events in temperate regions.I explored the effects of severe and fluctuating daily temperatures on aphid-parasitoid interactions, parasitoid life history, and community dynamics using both theoretical and experimental approaches.I first modelled the community level effects of daily maximum temperatures, the frequency of warmer-than-average days, and the autocorrelation of daily temperatures on a theoretical aphid-parasitoid community.Then I experimentally investigated influence of the frequency and amplitude of daily temperatures on trait-mediated indirect interactions between green peach aphids and A. matricariae.Finally, I assessed how development under extreme fluctuating temperature regimes influenced the life history characteristics of A. matricariae.The results from my studies suggest that increased frequency and severity of extreme warm temperatures can negatively impact populations, population interactions, and community dynamics.

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.
