Abstract

fetched live from OpenAlex

Monarch sommerfuglen (Danaus plexippus) er kjent for å migrere årlig fra Canada og nordlige deler av USA, til deres overvintrings sted i Mexico. For å finne frem på denne lange reisen, bruker sommerfuglene blant annet sola som et kompass. Siden været ikke alltid tillater at sola er synlig, så har jordas magnetfelt blitt foreslått som ett reserve kompass for sommerfuglene. Det er kjent at jordas magnetfelt blir brukt av migrerende og ikke migrerende dyr for orientering. Tidligere forskning gjort på Monarch sommerfuglene viser at de er sensitive til det magnetiske feltet, men lite er visst om hvordan jordas magnetiske felt påvirker de ikke-migrerende Monarch sommerfuglene. Ikke-migrerende Monarch sommerfugler beveger seg i mer avgrensede områder for å avle og finne mat. I denne studien, undersøker jeg om ikke-migrerende Monarch sommerfugler kan bruke jordas magnetiske felt til å holde en ønsket fly retning. For å teste dette, gjennomførte jeg adferds eksperimenter på festede sommerfugler i en flysimulator. Det magnetiske feltet ble manipulert ved bruk av et tredimensjonalt Helmholtz spole system. På gruppe nivå, fant jeg ingen resultater som tilsier at sommerfuglene bruker jordas magnetiske felt. Derimot, på individ nivå, var det en sommerfugl som endret sin fly retning nøyaktig med det magnetiske feltet. Derfor virker det som at de ikke-migrerende sommerfuglene kan bruke jordas magnetiske felt for holde en retning, men mer forskning burde bli gjort for tydeligere resultater. Dette prosjektet åpner for muligheten til å bruke ikke-migrerende Monarch sommerfugler til å forstå hvordan disse, og andre dyr bruker jordas magnetiske felt for orientering.

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.
