Abstract

fetched live from OpenAlex

La compréhension des mécanismes par lesquels les parasites peuvent influencer les espèces non hôtes est devenu un objectif capital dans le domaine de l'écologie évolutive.Cependant, la complexité des communautés naturelles, l'hétérogénéité de l'environnement, et l'histoire évolutive de l'hôte peuvent chacun exercer des effets importants et parfois imprévus sur les interactions hôte-parasite.Les résultats de la présente thèse représentent une illustration frappante d'une telle communauté naturelle.En déployant une combinaison de travail d'expérimentation et de manipulation sur le terrain je démontre que Gyrodactylus peut avoir des effets importants sur les traits d'histoire de vie des guppy, mais que ces effets n'influencent pas nécessairement les espèces non-hôtes, notamment en raison de la capacité de l'hôte de limiter ces effets.Attendu qu'aucune étude actuelle ne propose une analyse de l'impact de la coévolution guppy-Gyrodactylus sur la faune coexistante, je crois que ce travail a posé les bases pour de futures recherches portant sur à la pertinence écologique de Gyrodactylus.

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.
