Contrasting effects of climate warming on host-parasitoid interactions: insights from Rocky Mountain aspen leaf miners and their parasitoids
Bibliographic record
Abstract
Because temperature has pervasive effects on biological rates, climate warming may alter the outcomes of interactions between insect hosts and their parasitoids, which, for many host species, constitute the single largest source of mortality. Many studies report that climate warming is depressing the performance of parasitoids more than that of hosts. We examined this consensus by assessing the thermal ecology of a host-parasitoid interaction in the Rocky Mountains using wild populations of the aspen leaf miner (Phyllocnistis populiella) and a set of eulophid wasps that attack them. Host and wasp development rates were differentially sensitive to temperature. In addition, upper thermal limits in adult wasps were lower than those of host caterpillars, and wasps preferred low temperatures in choice experiments. When coupled to simulations of leaf microclimates in aspen canopies, these observations suggest, contrary to expectations, that climate warming is likely to benefit parasitoids at the expense of hosts.
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.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
