Abstract

fetched live from OpenAlex

Abstract Inversion polymorphism in populations of D. subobscura from a beech forest on Jastrebac mountain was studied in June 1990, 1993, and 1994, respectively. The same analysis was performed in 1990 for D. subobscura populations in a beech forest and an oak forest in the same region. Statistically significant differences in the frequencies of the gene arrangements of A, J and U chromosome were observed during the period of investigation. A tendency towards a decrease in the frequency of the standard gene arrangements was found for all chromosomes, but was particularly evident with chromosomes A and J. The frequency of the gene arrangements A1, A2, J1 and U1+2+6 increased at the same time. Differences in the frequency of the gene arrangements of A, J and U chromosomes were also observed when the populations from two ecologically different habitats (beech and oak forest) were compared in 1990. Zusammenfassung Der chromosomale Inversionspolymorphismus von Drosophila subobscura zeigt in Populationen von den Jastrebac-Bergen zeitliche und habitatsabhängige Veränderungen Der Inversionspolymorphismus von Drosophila subobscura von den Jastrebac-Bergen (Serbien) wurde im Juni 1990, 1993, und 1994 untersucht. Eine gleiche Analyse wurde 1990 in Populationen von D. subobscura in einem Birken- und in einem Eichenwald im selben Gebiet durchgeführt. Im Untersuchungszeitraum konnten statistisch signifikante Häufigkeitsverschiebungen für die chromosomalen Strukturtypen der Chromosomen A, J und U beobachtet werden. Eine Häunfigkeitsabnahme konnte für die Standardstrukturen aller Chromosomen, besonders aber für die der Chromosomen A und J aufgedeckt werden. Zur gleichen Zeit nahmen die Frequenzen der chromosomalen Strukturtypen A1, A2, J1 und U1+2+6 zu. Zwischen den Populationen aus den beiden ökologisch unterschiedlichen Arealen (Birken- und Eichenwald) zeigten sich ebenfalls Häufigkeitsunterschiede für die Strukturtypen der Chromosomen A, J und U.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
